    [0004] The present invention relates to a machine for encapsulating a product by means of an outer casing-forming fluid. It also refers to a process for encapsulating a product by means of an outer envelope-forming fluid and to the product directly obtained by said process.
    [0006] Background of the invention
    [0008] Processes for the encapsulation of products are known, such as that described in document US2015118365, where a product containing calcium is precipitated in the form of a drop in a sodium alginate solution placed in a tank. Once the droplet of calcium-containing product is introduced into the sodium alginate solution, it reacts chemically, thereby hardening the outer layer of the droplet of calcium-containing product. Said procedure has the drawback that encapsulation is not immediate, so that the drops must remain between 2 and 4 minutes in the sodium alginate solution for their outer layer to harden. During these minutes, the drops can settle to the bottom of the tank. This fact causes the drawback that the drops are not completely encapsulated, take an unsuitable shape or are arranged on other drops in formation, causing imperfections in the outer layer.
    [0010] Other procedures also comprise a stage in which the sodium solution is removed once the drops have been introduced. Said step is carried out by means of a tool, so that the drops containing calcium move inside the deposit favoring encapsulation throughout the outer layer. This stage of the procedure has the drawback that the drops can collide with each other, with the tank walls or with the tool, causing imperfections in the outer layer, or even breaking them.
    [0012] Document US4119739 describes a drop encapsulation process that comprises a previous stage of forming a film on the drops, and a second stage in which said drops preformed with the film are introduced into a solution with calcium ions located in a tank to finish hardening the outer layer. This deposit It has a device that creates bubbles in an area coinciding with the impact zone of the falling drops, so that the impact of these drops on the surface of the solution is mitigated. Therefore, imperfections are not created by the impact of the drop with the surface of the solution. However, the machine described in document US4119739 has the drawback that the definitive hardening of the outer layer occurs within the tank as the drop moves freely, being able to contact the walls of the tank or precipitate to the bottom creating imperfections in the outer layer of the drops in formation. Another drawback of the drop encapsulation technique lies in the fact that it does not make it possible to achieve spheres with a diameter greater than 10 mm due to the physical limitations of air-liquid surface tensions (Tate's law).
    [0014] It is therefore clear the need to have a machine that allows obtaining a product such as a sphere, with a section with a diameter greater than 10mm, in an easy way and without imperfections.
    [0016] Description of the invention
    [0018] The objective of the present invention is to solve the aforementioned drawbacks by developing a machine and a method to encapsulate a product by means of a fluid that forms an outer envelope.
    [0020] In accordance with this objective, according to a first aspect, the present invention refers to a machine comprising at least one conduit containing a fluid that forms the outer casing, said conduit comprising a first section provided with an inlet for introducing the product , and a second section provided with an outlet to extract the product once encapsulated. Said machine is characterized by the fact that it includes drive means to actively impel inside the conduit, a flow of fluid forming the outer casing directed toward the inlet section, at least one intermediate section of said conduit comprising means of interference arranged to generate a fluid flow of turbulent regime capable of keeping the product in oscillating movement in the intermediate section of conduit for a determined time.
    [0022] According to the same objective, according to a second aspect, the present invention refers to a process for encapsulating a product, by means of the claimed machine comprising the steps of;
    [0023] a) introduce a product into the duct through the inlet section, b) impel a flow of fluid forming the outer casing inside the duct directed towards said inlet section,
    [0024] c) during step b), generating a turbulent flow of the envelope-forming fluid in at least one intermediate section of the interior of the conduit,
    [0025] d) keep the product in oscillating motion in the intermediate section with turbulent flow for a determined time to form a layer of the outer casing, and
    [0026] e) modifying the speed of the casing-forming fluid flow to allow the advance of the product towards the outlet section.
    [0028] According to the same objective, according to a third aspect, the present invention relates to a product obtained by the claimed process. Preferably, said product is characterized by the fact that once encapsulated, it has a diameter equal to or greater than 15mm.
    [0030] In the present invention, encapsulation means the formation of an outer shell on a product. For example an envelope obtained by gelling by means of a gelling substance. This encapsulation technique is commonly known as “spherification” or “spherification”, (Alicia and elBullitaller. Gastronomic scientific lexicon. (2006), p. 28).
    [0032] Optionally, the gelling substance is contained in an outer shell-forming fluid, which is capable of reacting with a component of the product to be encapsulated. Preferably, the hydrocolloid gelling substance is, for example, sodium alginate. However, the outer shell-forming fluid can be a fluid with a gelling substance selected from iota, furcelarate, kappa, xanthan, and agar-agar.
    [0034] The product to be encapsulated is preferably a product containing a calcium component, for example calcium salts, capable of reacting with, for example, sodium alginate at an optimum operating temperature of between 10 and 50 degrees centigrade. Preferably, between 20 and 40 degrees centigrade. The reaction between the calcium component of the product and the gelling substance creates a gel-like envelope that envelops the product. Optionally, the product to be encapsulated is previously frozen for easy handling and so that the formation of the envelope occurs progressively as the product thaws. For greater efficiency of the reaction and greater uniformity of the outer envelope, the product to be encapsulated is immersed in the fluid forming the outer wrap.
    [0036] In the present invention, thanks to the fact that a flow rate of fluid forming the envelope is propelled inside the conduit, turbulent flow of fluid is created in the intermediate sections that include the interference means, allowing the product to be moves through the interior of the conduit is stopped, so that it moves in an oscillating manner while the flow rate of fluid forming the envelope is constant. This oscillating movement allows to create the outer casing of the product in a uniform way and without the product contacting the walls of the duct so that imperfections are not created in the outer casing. However, by modifying the casing-forming fluid flow rate, for example by reducing it, the product can advance to the next leg to reach the outlet.
    [0038] Thus, a machine and a process are obtained to encapsulate a product that allows to quickly and easily create an outer casing in a solid or liquid product, frozen or not. Likewise, during the creation of the outer casing, the product to be encapsulated does not contact elements that may cause imperfections. Furthermore, the claimed machine allows the outer casing to be created automatically, without the intervention of an operator.
    [0040] The product obtained from the procedure has a geometry with an outer envelope without imperfections. Additionally, encapsulated products can have diameters equal to or greater than 15mm, since the process is not affected by the physical limitations of surface tensions described according to Tate's law.
    [0042] Some embodiments of the machine and method according to the dependent claims described below are described below.
    [0044] Preferably, the machine comprises a plurality of intermediate sections of conduit, each provided with interference means arranged to generate, in each of said intermediate sections, a turbulent flow capable of maintaining a product in oscillating movement. In this way, a plurality of outer casings to a plurality of products can be simultaneously created in a conduit. The interference means are distributed in a determined way along the conduit through which the product to be encapsulated advances. The product to be encapsulated advances through the conduit, overcoming a certain number of interference means where the turbulent flow until reaching the outlet section.
    [0046] In the intermediate sections provided with the interference means, the flow of fluid forming an outer envelope creates a turbulent regime of the fluid, so that it stops the advance of the product to be encapsulated by causing it to move in an oscillating manner in the vicinity of the intermediate sections. Additionally, the constant flow rate allows the outer shell to be created uniformly over the entire outer surface of the product.
    [0048] According to a preferred embodiment, the interference means comprise a restriction of the section of the duct in the intermediate section, the product being capable of overcoming the restriction and advancing towards the outlet section when the flow speed of the fluid forming the envelope is modified. Exterior. For example, the interference means may comprise a constriction provided in the lumen of the intermediate length of conduit. Thus, when the speed of the outer casing-forming fluid flow is changed, for example when it is reduced, the casing-forming fluid flow allows the product to advance to the outlet. However, when the casing-forming fluid flow is constant and, with certain characteristics, an intermediate section of turbulent flow is created in the restriction that does not allow the product to advance to the outlet section.
    [0050] Preferably, the machine comprises a plurality of conduits containing outer shell-forming fluid, each of the conduits including at least one section provided with interference means arranged to generate a turbulent flow of the outer shell-forming fluid. In this way, the machine makes it possible to encapsulate a plurality of products in a plurality of conduits simultaneously, making it efficient and increasing its productivity.
    [0052] Advantageously, the machine comprising a collecting tank arranged to receive the products at the outlet of the duct, or plurality of ducts, the collecting tank including a determined volume of fluid forming the outer shell.
    [0054] In this way, the collection of encapsulated products is simplified by being concentrated in a single tank, where all the encapsulated products are deposited. Thus, the machine is provided with a container into which to pour the encapsulated product to later be processed, for example packed and / or labeled. The collection tank contains a volume of fluid that forms the envelope exterior, so that a direct impact on a solid surface is avoided, which during the pouring phase of the product can create imperfections in the outer casing.
    [0056] According to a preferred embodiment, the outlet section of each of the conduits comprises a pivoting gate arranged to receive the product once encapsulated and pour it into the tank. In this way, the gate makes it possible to isolate the conduit through which the flow of fluid forming the outer casing circulates from the rest of the machine, minimizing losses of fluid forming the outer casing. Optionally, the gate comprises an opening sized for inserting the product into its interior and a means of rotating said gate for the discharge of said product into the collecting tank.
    [0058] According to an alternative embodiment, the pivoting gate is arranged submerged in the fluid of the collecting tank. In this way, in the event of loss of fluid forming the outer casing, these are poured into the collecting tank. Additionally, a gas or other fluid is prevented from being introduced into the conduit.
    [0060] Preferably, the conduit, or plurality of conduits, containing the outer shell-forming fluid are arranged substantially vertically in a frame of the machine. In this way, the force of gravity moves the product down the inside of the duct without the need for it to be moved by another element or device. Optionally, when the flow rate is constant, the product stops its advance in the intermediate sections as a turbulent flow of fluid forming the outer envelope is created in the intermediate sections.
    [0062] Advantageously, the product to be encapsulated is a food product containing a calcium component capable of forming an outer gel-like envelope with the fluid forming the envelope. For example, the product is a drink with alcohol such as whiskey, gin, rum, vodka, beer among others, or a non-alcoholic drink such as fruit and / or vegetable juice, a soft drink, a soup, a cream or milk among others or a combination of both.
    [0064] Preferably, the drive means comprise a pump and a hydraulic circuit for recirculation of the flow of fluid forming the outer casing. In this way, a hydraulic circuit is created to recirculate the fluid that forms the outer casing, taking advantage of the fluid to encapsulate more than one product.
    [0065] According to an alternative embodiment, the machine comprises a reserve tank where the liquid that forms the outer envelope accumulates from the circulation through the conduit which is subsequently driven again, by means of the drive means, through the conduit. In said alternative embodiment, the recirculation conduit is arranged between the reserve tank and the conduit.
    [0067] According to the claimed process, before step a) the solidification step of the liquid fluid of the product to be encapsulated is carried out. In this way, the product adopts a state that allows it to be manipulated and encapsulated with greater ease and efficiency. Said solidified product can be, for example, in the shape of a hemisphere. In this way, it is avoided that the product is divided into smaller portions that can mix with the fluid that forms the outer casing, creating a solution that is not suitable for the correct operation of the machine. In the same way, said portions of product can become encapsulated in the conduit and damage the next cycle of products to be encapsulated.
    [0069] In a preferred embodiment, the product is a frozen liquid. In this way, it progressively thaws on contact with the outer shell-forming fluid and the outer shell is created as the product thaws. For this embodiment, the machine comprises a heating device for the fluid forming the outer casing that maintains the temperature of the fluid forming the outer casing at an optimal working temperature. In this way, it is avoided that the constant introduction of products in the frozen state from cooling the fluid that forms the outer shell and, as a consequence, that the product to be encapsulated is not properly encapsulated and must be discarded.
    [0071] According to one embodiment of the method, step c) comprises generating a turbulent flow in a plurality of intermediate sections of conduit. In this way, the conduit through which a flow of fluid that forms an outer envelope is circulated has a plurality of intermediate sections where turbulent flows are generated. Optionally, in said intermediate sections with turbulent flow regime is where the product is kept to form the outer envelope of the product. So, if a greater thickness of the outer casing is desired, the product must simply be kept submerged for a longer time in the outer casing-forming fluid, specifically in the intermediate section where a turbulent flow will be generated so that the product remains in oscillating motion.
    [0073] Advantageously steps c), d) and e) of the process comprise progressively repeating the following sub-stages until the product reaches the outlet section;
    [0074] d1) keep the product in oscillating motion in an intermediate section for a certain time to form a first layer of the outer casing, e1) modify the speed of the casing-forming fluid flow to allow the advance of the product towards a consecutive intermediate section, Y
    [0075] c1) again generating a turbulent flow of the envelope-forming fluid in the consecutive intermediate section to be able to form a second outer envelope layer.
    [0077] In this way, a conduit having a plurality of intermediate sections will progressively create the outer envelope in a multitude of intermediate sections, so that in each intermediate section a portion of said outer envelope will be formed.

    [0093] Description of a preferred embodiment
    [0095] A preferred embodiment of machine 1 will now be described with reference to Figures 1 to 5.
    [0097] In said embodiment, the product to be encapsulated is a previously frozen liquid comprising a calcium component. Furthermore, said product can be a product suitable for consumption. Additionally, the product to be encapsulated has a sphere-shaped geometry after it is frozen. Optionally, the outer shell-forming fluid is a fluid comprising sodium alginate and is at a temperature of 30 degrees centigrade.
    [0099] The machine 1 of the present invention comprises a plurality of conduits 2 through which a fluid forming the outer casing is circulated. These conduits 2 comprise in the upper part a first section 2a with an inlet 3 to introduce the product 7 to be encapsulated and in the lower part a section 2e with an outlet 5 for the extraction of the already encapsulated product 7. Additionally, the conduits 2 include intermediate sections 2b, 2c, 2d provided with restrictions 4 that create a turbulent flow of fluid forming the outer envelope when a constant flow is circulated through conduit 2. In these sections 2b, 2c, 2d intermediates, the product 7 is capable of remaining in oscillating motion while there is a turbulent flow of the fluid forming the outer shell (see Figures 3 to 5), in this way the outer shell is created in a uniform and without the product suffering imperfections.
    [0101] The described embodiment also has a hydraulic pump (not shown), as drive means, to actively impel inside the conduit 2 a constant flow rate of fluid that forms the outer envelope towards the inlet section 2a. 3 of conduit 2.
    [0102] As can be seen in Figures 3 and 4, a multitude of restrictions 4 are uniformly distributed along the ducts 2. These comprise dimensioned constrictions, so that the product 7 can overcome them by moving towards the outlet section 2e 5 when the speed of the flow of fluid forming the outer envelope that circulates inside the conduit 2 is modified (see figure 4). In the embodiment described, the duct 2 has an internal diameter of at least twice the diameter of the product 7 to be encapsulated, and the constraints 4 define a passage channel with a passage width 2 mm greater than the diameter of the product. 7 to encapsulate.
    [0104] The ducts 2 are distributed along the same plane and arranged vertically on a frame of the machine 1, so that the force of gravity acts on the product 7, moving it inside. Additionally, in the upper part of the ducts 2, a mechanism for inserting the products 7 is located, coinciding with the inlets 3. This mechanism comprises a driving element 10 attached to a shaft 11, so that when it rotates it drives a connecting rod 12 which in turn vertically displaces a plate 13 with protrusions 14. This plate 13 with protrusions 14 is guided by rods 15 so that during vertical movement, said protrusions 14 contact a mold 16 located in the lower part of the insertion mechanism. Previously, the products 7 have been arranged in the mold 16 to be frozen. The protrusions 14 when contacting the mold 16 cause the products 7 to be separated from the mold 16 and introduced into the conduits 2 through their respective inlets 3 of the section 2a (see Figures 1 and 2).
    [0106] In the lower part of the conduits 2, specifically attached to the section 2e of the outlets 5 of the conduit 2, there are gates 8 that act to pour the encapsulated product 7 into a collecting tank 6. The preferred embodiment that is described comprises a single tank 6 where the products 7 from a multitude of pipes 2 are poured. However, the discharge of the products 7 can be carried out in collecting tanks 6 of smaller dimensions located at the bottom of each pipe. two.
    [0108] In the embodiment described, the gate 8 is located above the level of fluid forming the outer envelope of the interior of the collection tank 6. The gate 8 comprises an opening 17 dimensioned for the insertion of the product 7 in its interior and of some means of rotation, specifically a shaft 18 connected to a multitude of gates 8 moved by a motor 19, for the pouring of the product 7 into the tank 6 collector. Gate 8 is rotatably displaced from a position where the gate The opening 17 is arranged coincident with the outlet 5 of the section 2e of conduit 2 to receive the encapsulated product 7, to a position in which the opening 17 is located opposite the outlet 5 of the section 2e of conduit 2, so as to allow the discharge of the product 7 to the collecting tank 6, and vice versa (see figure 4).
    [0110] In a preferred embodiment not shown, the machine 1 comprises a recirculation conduit for the fluid forming the outer casing, where one of its ends is located in the inlet section 2a 3 of the conduit 2. In this way, the evacuation of the fluid is allowed. Former of the outer casing that has already been used to encapsulate the product 7, and where the opposite end of said recirculation conduit is located so that the fluid forming the outer casing is poured into a collecting tank 6 to be reused by urging it new inside the conduit 2. However, in an alternative embodiment not shown, the opposite end of said recirculation conduit is located, so that the fluid forming the outer envelope is poured into a reserve tank to be reused by pushing it by means of driving back into duct 2.
    [0112] According to an alternative embodiment not shown, the machine 1 comprises a heating device (not shown) for the fluid forming the outer casing to maintain the temperature of the fluid forming the outer casing at an optimum operating temperature. Preferably, the heating device (not shown) is located before the impulse means (not shown), so that the outer shell-forming fluid that is forced into the conduit 2 has the appropriate operating temperature.
    [0114] The following describes the encapsulation procedure of a product 7 by means of a machine 1 of the described embodiment, according to Figures 1 to 5.
    [0116] In a first stage, the product to be encapsulated is frozen, preferably in a mold 16. Subsequently, an operator places the mold 16 with a multitude of products 7, on the machine 1, so that the products 7 are placed coincident in the entrances 3 of the sections 3b of the ducts 2 (see figure 1).
    [0118] The insertion mechanism is then operated, so that the plate 13 with protrusions 14 moves vertically until it contacts the mold 16. Separating the multitude of products 7 and introducing them into the respective entry sections 2a 3 (see figure 2).
    [0120] Simultaneously, inside the conduit 2 a flow of fluid forming the outer casing is impelled at a constant flow rate and directed towards the inlet section 2a 3, that is, in the opposite direction to the downward movement of the product 7 to be encapsulated. The flow of fluid forming the outer envelope decreases the speed of movement of the product 7 to be encapsulated, until it is located in a first intermediate section 2b of turbulent flow rate of fluid forming the outer envelope generated in a first restriction 4. The product 7 is kept in oscillating motion in the vicinity of the restriction 4, so that it does not touch the walls of the duct 2 and a first outer shell layer is created (see Figures 3 and 4).
    [0122] After a certain time, the turbulent flow regime is modified by reducing its velocity, so that the product 7 advances towards the intermediate section 2c of the turbulent regime flow. Subsequently, the turbulent flow of fluid is modified to the initial conditions and a second product 7 is simultaneously introduced into the conduit 2, through the inlet 3 of the section 2a. Said second product 7 will start a new production cycle.
    [0124] After advancing to the intermediate section 2c and with the initial conditions of the turbulent flow regime of fluid, the product 7 of the first cycle repeats the process of maintaining an oscillating movement in the vicinity of the restriction 4, so that it does not touch the walls of duct 2 and a second outer shell layer is created (see Figures 3 and 4). The previous process steps are repeated until the product 7 reaches the section 2e of outlet 5.
    [0126] Once the product 7 reaches said outlet section 2e, it advances until it enters a gate 8 through the opening 17 located coincident with the outlet 5 of section 2e located in the lower part of the duct 2. When the product 7 is introduced In gate 8, the outer layer is formed so that it does not suffer from imperfections. Said gate 8 is operated by means of rotation, specifically a motor and a shaft, so that it moves from a position in which the opening 17 is arranged coincident with the outlet 5 of the conduit 2 to receive the encapsulated product 7, to a position in which the opening 17 is located opposite the outlet 5 of the conduit 2, so as to allow the product 7 to be poured into the collecting tank 6 (see figure 4).
    [0127] Subsequently, an operator extracts the already encapsulated products 7 from the collecting tank 6.
    [0129] Despite the fact that reference has been made to a specific embodiment of the invention, it is obvious to a person skilled in the art that the machine and processes described are susceptible to numerous variations and modifications, and that all the mentioned details can be substituted by others technically equivalents, without departing from the scope of protection defined by the appended claims. For example, although an encapsulation in which the product is frozen has been described, this could also be a fluid in a liquid state. Similarly, although it has been described that the formation of an outer envelope by means of a gelling substance comprising sodium alginate, this could also be formed by a gelling substance selected from iota, furcelarate, kappa, xanthan and agar-agar. Similarly, although gelling has been described in which the product is in the shape of a sphere, it could also have a different geometry than a sphere and determined for its subsequent encapsulation.
