    DEVICE FOR OPTIMIZING FRUIT WASHING
    DESCRIPTION OBJECT OF THE INVENTION
    The invention consists of a new device that optimizes the washing of fruits and the like by spraying, such as vegetables, in post-harvest treatment facilities, where the fruit is subjected to different washing and disinfection, rinsing and drying processes. .
    The invention describes a new device that provides a washing and disinfection of the fruit that improves current systems, especially in terms of water consumption per unit of washed product, which also results in significant savings in the subsequent drying phase, to get to treat the product with less water. BACKGROUND OF THE INVENTION
    In fruit stores, fruits intended for fresh consumption are subjected to different treatments to improve their presentation, eliminating the dirt they can drag from the field and to protect them from the attack of fungi and other microorganisms, thus allowing a better conservation of Fruit properties and longer storage periods. These treatments mainly consist of showers and baths with detergents and fungicides.
    For this, it is known to use systems in which the fruit, previously selected by size, is arranged on a transport line on which it comprises transversely a conduit comprising nozzles, to spray water mixed with soap and perform its washing. These systems consume a large amount of water, with average consumption between 2000 and 2500 liters / hour, which constitutes an inconvenience for the environment, both due to the increase in the price of water and the obligation to condition its discharge to the parameters established by the law.
    In this regard, the application U201231146, belonging to the same holder as the present invention, which describes a device for application of spray products of the type described above in which the quantity of product to be applied is regulated according to the quantity of product can be cited that circulates on the transport line and the weight of each piece of product that circulates on a transport line, which reduces the consumption of water in the wash. At this point it is important to point out that in the state of the art it is envisaged that after rinsing a rinse will be carried out, for which conventional devices have rinsing means that comprise a conduit with nozzles transversely to the transport line, for spray water mixed with fungicide, to rinse the previously washed fruit. This rinse is not performed optimally since its configuration does not allow optimization.
    Additionally, the application U200501944 can be cited, which describes a device for the purification of wastewater resulting from the washing and rinsing of the fruit and the like. DESCRIPTION OF THE INVENTION
    In order to achieve the objectives and solve the aforementioned drawbacks, the invention provides a new fruit washing device that optimizes the washing process by reducing the amount of water needed to perform the washing and rinsing, which
    It also reduces the amount of energy needed to dry the fruit, having the fruit washed and rinsed a smaller amount of water deposited on its surface.
    The invention is applied in devices comprising a conveyor line in which the fruit to be washed is deposited and on which it includes at least means for rinsing the fruit, which are provided with electronically adjustable nozzles by means of a controller configured to generate a signal of frequency proportional to the amount of fruit deposited on the conveyor line, and perform the proportional application of flow rate depending on the fruit deposited on the conveyor line.
    The main novelty of the invention is that the rinsing means comprise at least two rinsing pipes, each provided with nozzles governed by the controller. The rinsing pipes are connected to a common network of constant pressure water; to provide by means of said nozzles a homogeneous rinse flow rate proportional to the amount of fruit deposited in the transport line.
    In the preferred embodiment of the invention, the nozzles of each of the two rinse lines are arranged to the three-pin, and separated a distance without overlapping in the spray covering the entire width of the conveyor line. These nozzles are of the flat cone type of great taper to cover a larger spray surface. The described configuration avoids wasting water spray between the brushes of the conveyor line that is currently produced. As for the drop size, a small droplet size was selected that allows low flow rates to be used without compromising its maintenance by unwanted emboces. This achieves greater uniformity in consumption per nozzle providing greater uniformity in application.
    The invention provides that on the conveyor line, and before the rinsing means, it comprises washing means, provided with at least one washing line that includes electronically controllable nozzles, so that the conduction of said washing means is connected to the network common water at constant pressure, so that said nozzles provide a wash flow proportional to the amount of fruit deposited in the transport line, so that both the washing and the rinsing achieve a reduction in the amount of water consumed.
    The invention also provides that the water network and prior to its connection with the rinse lines, comprises a fungicide application dispenser, such as biocide, and the wash line comprises a detergent application dispenser. In this way, the fungicide application dispenser and the detergent dispenser are connected to the controller to regulate its individual application in the wash and rinse in proportion to the amount of fruit deposited in the conveyor line. This configuration, apart from saving water, also saves the amount of fungicide and detergent to be applied.
    Finally, it should be noted that the controller is also configured to record the consumption of water, detergent and fungicide for subsequent statistical treatment, which allows the control of these parameters. This provides a lower consumption of reagents and products for water treatment, controls, savings in handling and purification.
    Therefore, the invention consists in the use of two rinsing lines with electrically operated nozzles arranged next to each other, which are actuated by electric opening or closing signals, whose operating frequency determines the application flow, said frequency being of actuation a function of the values detected by the system described in the utility model U201231146, and which in any case assumes
    not to exceed 100 liters per hour of water as a whole, compared to 2100 liters consumed by current washing systems.
    Consequently, the invention minimizes the flow of water with detergents proportionally to the flow of the fruit. In accordance with the above, it also minimizes the flow of water with fungicides.
    In addition to the described configuration, the pre-drying tunnels can be programmed at a lower temperature than the current systems, since the washed and rinsed fruit comes out with a smaller amount of water on its surface, allowing economic savings around the 5% for each degree of reduction.
    By having a lower water consumption, the CO2 emission and the minimization of wastewater are also reduced.
    Next, in order to facilitate a better understanding of this specification, and as an integral part thereof, a single figure is attached in which the object of the invention has been shown as an illustrative and non-limiting nature. DESCRIPTION OF AN EXAMPLE OF EMBODIMENT OF THE INVENTION
    Figure 1.- Shows a diagram of an embodiment of the device of the invention. DESCRIPTION OF AN EXAMPLE OF EMBODIMENT OF THE INVENTION
    A description of the invention based on the above-mentioned figure is given below.
    The invention is applied in transport lines 1 in which the fruit 2 to be washed is deposited, so that it comprises a controller 3 which, from sensors 4, is configured to detect the amount of fruit deposited in the conveyor line 1 and generate a frequency signal proportional to the amount of fruit deposited on said conveyor line 1. An example of the controller 3 may be that described in the Spanish utility model with application number 201231146, so it is not described in greater detail.
    On the conveyor line 1 it comprises washing means 5 constituted by a washing line 6 with nozzles 7, of electronic opening / closing and connected to the constant pressure water network 8. The nozzles 7 are connected to the controller 3, to govern the opening / closing of the nozzles 7, so that it provides a spray rate proportional to the amount of fruit deposited on the conveyor line 1 by generating a nozzle drive signal whose frequency determines the flow of application of showering of the fruit, since said frequency is proportional to the quantity and volume of the pieces to be washed that are introduced into the machine.
    Following the washing means 5 it comprises rinsing means 9 that have a novel configuration that facilitates the rinsing of the fruit, and which comprises two rinsing pipes 10 with nozzles 7, the operation of which is also governed by the controller 3. Said lines rinse 10 are connected to the water network 8, so that they provide a spray rate proportional to the amount of fruit deposited on the conveyor line 1.
    The water network 8, before the washing line 6 of the washing means 5, is connected to a detergent dispenser 11, and before the two rinse lines 10 of the rinse means 9, is connected to a dispenser 12 of biocide, which together with the detergent dispenser 11 is governed by the controller 3, so that the detergent and biocide are applied proportionally to the frequency of the generated signal of opening of the nozzles and therefore depending on the amount of fruit deposited on the conveyor line
    one.
    The nozzles 7 of each of the lines 10 of the rinsing means 9, are arranged one after the other and according to a three-pin configuration, and separated a distance without overlapping in the spray to cover the entire conveyor line 1.
    The configuration described minimizes the flow of water with detergents and biocide proportional to the flow of the fruit, which in any case means not exceeding 100 liters per hour of water as a whole, compared to the 2100 liters consumed by current washing systems .
    A nozzle with electronic regulation in on-off cycles, of flat cone type and high taper was selected, which allows covering the largest possible area with the smallest number of nozzles 7 applying the water sprayed on all the brushes that constitute the conveyor line, which avoids wasting water spray between brushes that is currently produced. As for the drop size, a small droplet size was selected that allows low flow rates to be used without compromising its maintenance by unwanted emboces. This achieves greater uniformity in consumption per nozzle providing greater uniformity in application.
    All consumptions, both water and soap and biocide are registered by controller 3 for subsequent statistical treatment. This provides a lower consumption of reagents and products for water treatment, controls, savings in handling and purification, since the residual water resulting from the washing and rinsing performed is collected in a tank 13 for purification by means of a purification device 14, such as for example, the one described in the patent with application number 200501944, whereby a smaller amount of water, detergent and biocide is consumed, facilitates and simplifies its purification.
    Once washed and juagada, the fruit is dried, so that with the described configuration it is allowed that the drying tunnels can be programmed at a lower temperature than the current systems, allowing an economic saving of around 5% for each degree of reduction. This is because the washed and rinsed fruit comes out with a smaller amount of water on its surface.
