    [0001]
    [0002] Industrial method of continuous processing of particulate food ingredients.
    [0003]
    [0004] SECTOR OF THE TECHNIQUE
    [0005]
    [0006] The present invention belongs to the field of the food industry.
    [0007]
    [0008] In particular, it refers to a new system for processing particulate solid ingredients that can be applied in many industrial processing processes, being especially indicated for the rehydration, cooking and sterilization of legumes and cereals, and for the sterilization of fruits and vegetables.
    [0009]
    [0010] BACKGROUND OF THE INVENTION
    [0011]
    [0012] The use of legumes in food is a millenary tradition that comes from human prehistory, including under this denomination a great variety of seeds of plants that are classified in Botany as legumes, among which stand out the beans, chickpeas, lentils, peas and lupines.
    [0013]
    [0014] Traditionally, in the domestic kitchen it is customary to leave the vegetables to soak for several hours (usually during the night) before being cooked. In this process of hydration, the legume absorbs a large amount of water, normally increasing its weight to more than twice its initial dry weight, which allows to reduce the time necessary for the correct cooking of the legumes and to obtain a final texture uniform and soft.
    [0015]
    [0016] With the development of the food industry, this same hydration process has been transferred to an industrial scale, and it is usual for factories that produce cooked vegetables or other food products based on legumes to have specific facilities for the previous hydration of legumes. dry, which is normally done in tanks or rafts in which the vegetables are placed and are flooded with water during the time required to complete the hydration.
    [0017]
    [0018] The main drawback of this hydration process is that it usually requires a relatively long time, greater than 8 or even 12 hours, which requires accumulating a very large volume in the hydration tanks to maintain industrial production, and these conditions of work with long times and large volumes generate significant complications and costs in the industrial process, which requires a large amount of human labor, consumes large amounts of energy and water, and affects the quality of the final product because of not being able to precisely control the conditions and hydration times and microbiological risks during the process, and that the humidity and temperature conditions are ideal for microbial proliferation.
    [0019]
    [0020] There are few inventions specifically referring to methods that improve the hydration of legumes or reduce the time required for this, since most of the patents registered so far describe or protect specific hydration conditions that are adequate to confer a certain quality to the legume treated, as it may be that of rapid cooking, or that improves its digestibility, etc., but methods or machinery are not defined to improve or accelerate the hydration process itself. However, we can cite as background of our invention:
    [0021]
    [0022] - The patent US3869556A, which proposes a process of treating chickpeas and red beans to be quick cooking, in which certain hydration conditions are specified for a time of 24 hours.
    [0023]
    [0024] - The patent US4729901A, which proposes a canned legume manufacturing process in which a specific formulation of additives in the water of hydration is specified.
    [0025]
    [0026] - The patents US6355291B1, US6465031B1 and US20060198934A1 describe methods of preparation of legumes to improve their digestibility and reduce the generation of flatulence, for which several stages of hydration are described with different temperatures and chemical compositions for purposes other than the optimization of hydration itself , and without defining the industrial machinery used in the process.
    [0027]
    [0028] - The patent US3869556A, which proposes a process of treating chickpeas and red beans to be quick cooking, in which certain hydration conditions are specified for a time of 24 hours.
    [0029]
    [0030] - The patent US8003154B2, in which a refritos bean manufacturing process is proposed in which a nonspecific hydration step is included.
    [0031] - The patent US6033692A, which proposes a method of hydration of legumes with the purpose of reducing the hydration time thanks to an enzymatic treatment performed by certain agents added to the water of hydration.
    [0032]
    [0033] Regarding the industrial cooking of legumes and the thermal treatments of fruits and vegetables, there are many methods already established, some of them specifically defined for continuous production, but none anticipates the inventive novelty that is the subject of this patent application. Anyway, we can cite as background of this invention:
    [0034]
    [0035] - The patent US4214013A, in which a method of cooking legumes with a process liquid in a process vessel is proposed, from which both components are extracted together.
    [0036] - Patents US4155293A and US4561347A, propose methods that use continuous cooking vessels, but are horizontal containers.
    [0037]
    [0038] - The patent US5374435A, in which a method of cooking particulate products with a process liquid in a process vessel is proposed, but it does not work continuously.
    [0039]
    [0040] - The patent DE19805773A1, which defines a method of sterilization of particulate products without process liquid.
    [0041]
    [0042] - The patent US20010047814A1, which defines a method of sterilizing fruit continuously by immersion in a liquid through a horizontal container.
    [0043]
    [0044] - Patent EP0272087B1, which proposes a method of continuous sterilization of a particulate product that advances together with a process liquid.
    [0045]
    [0046] EXPLANATION OF THE INVENTION
    [0047]
    [0048] The new industrial method of processing object of this invention is based on a very simple principle that, however, has not been used until now in the processes of industrial processing of particulate solid food ingredients: the ability to make a liquid flow through solid particles that move in the opposite direction of the liquid.
    [0049]
    [0050] Taking advantage of this principle, according to this new method, the solid ingredient is introduced continuously through the upper part of a vertical process vessel and descends through the interior of the container, while a process liquid is also introduced continuously by the bottom of the container and going up in countercurrent flowing between the solid particles of the ingredient.
    [0051]
    [0052] The processed solid ingredient is extracted continuously as it reaches the bottom of the process vessel, while the process liquid is extracted from the top of the process vessel, also continuously.
    [0053]
    [0054] For the introduction of the solid ingredient by the upper part of the vertical process vessel use the appropriate means, such as conveyor belts, pneumatic transport, etc. that discharge into the upper part of the process vessel.
    [0055]
    [0056] For the extraction of the solids from the bottom of the process vessel, a pumping system is used, followed by a possible total or partial reintroduction of the extracted process liquid together with the solids.
    [0057] Along the vertical process vessel, there may optionally be output and inlet connections of process liquid, at different height levels. This makes it possible to modify the conditions of the process liquid that flows inside the container, to increase or reduce its temperature (by passing it through an external heat exchanger), modify its composition (adding or removing components or additives) or vary its flow (adding new liquid or removing part of the extracted liquid).
    [0058]
    [0059] In this way, specific process conditions can be regulated at each level of height along the process vessel.
    [0060]
    [0061] For the introduction, reintroduction or extraction of the process liquid in the lower part, in the intermediate levels and in the upper part of the process vessel, the appropriate means are used, normally centrifugal impulse pumps.
    [0062]
    [0063] This new method that we have just described makes it possible to simplify and precisely control various manufacturing processes that are very common in the food industry, such as washing, hydration, cooking or sterilization of particulate ingredients, separately regulating the inflows and outflows of the products. solid ingredients and the process liquid, and controlling at each stage of the process their specific conditions, which improves the quality of the final product, while reducing process times and water and energy consumption, so this method It is very appropriate for the growing global demand for industrially processed foods.
    [0064]
    [0065] PREFERRED EMBODIMENTS OF THE INVENTION.
    [0066]
    [0067] A first preferred embodiment of the described method allows the hydration of legumes, reducing very significantly the time necessary to complete the hydration process, based on the behavior of legumes when they are subjected to temperature changes during hydration, precisely the alternating contact with hot water and cold water which accelerates the process of hydration of the legume.
    [0068]
    [0069] For this preferred embodiment, two intermediate levels of reconditioning of the process liquid are established in the vertical process vessel, so that hydration water at a temperature of around 80 ° C is introduced through the lower part of the vertical vessel. extracted in the first intermediate level to be cooled and reintroduced at a temperature around 35 ° C, and is extracted again in the second intermediate level, to be heated again up to a temperature around 80 ° C.
    [0070]
    [0071] In this way, the vegetables that are being hydrated, as they descend through the interior of the process vessel are first in contact with hot water, then, in a second stage of the process they are in contact with cold water and finally, in a third stage of process are again in contact with hot water.
    [0072] A second preferred embodiment of the invention allows the cooking of pulses in a continuous line, with separate obtaining of the aquafaba (liquid phase resulting from cooking).
    [0073]
    [0074] In this second embodiment, the pulses are introduced continuously into the vertical process vessel, where they are cooked while they descend inside, in countercurrent with the cooking water that advances in the opposite direction, the cooking temperature being controlled and regulated to along the process vessel by injecting steam at various intermediate height levels of the vessel.
    [0075]
    [0076] In this case, the vertical process vessel can be pressurized to allow the cooking of the legume at a temperature higher than 100 ° C, having a suitable system to allow the introduction of the legumes in the pressurized container.
    [0077]
    [0078] At the upper part of the process vessel, the cooking water that has completed its path through the container is extracted continuously. This vegetable cooking water is known as aquafaba and has a growing demand in the market as a natural and vegetable substitute for egg white.
    [0079]
    [0080] The container can also have a final cooling section of the cooked vegetables before they are extracted from the lower end of the container. For this, it is simply necessary that the cooking water introduced by the lower part of the container between cold, since it will be preheated by the own vegetables that are being cooled and later will reach the adequate temperature for the cooking of the vegetables thanks to the injection of steam at intermediate height levels of the process vessel.
    [0081]
    [0082] A third preferred embodiment of the invention which also has a great potential for use in the food industry is the continuous sterilization of chopped fruits and vegetables, for which the pieces are introduced by the upper part of the vertical process vessel and are subjected to to a first stage of heating until reaching the desired sterilization temperature, then continue its descent by the process vessel in a second stage of maintaining its temperature and finally go through a third stage of cooling before being extracted from the process vessel .
    [0083]
    [0084] In this third preferred embodiment, the process water entering through the lower part of the vertical process vessel may have been previously sterilized, to avoid contamination of the pieces that are being cooled after having been sterilized, so that said pieces may be directly packed in aseptic conditions.
