    OPTIMIZATION SYSTEM OF THE TREATMENT BALANCES IN POSTCOSECHA PROCESSES

    DESCRIPTION
     5
    OBJECT OF THE INVENTION

    The present invention, as expressed in the statement of this specification, refers to a system for optimizing treatment broths in post-harvest processes, where the use and reuse of water 10 used in the treatment in which washing of agricultural products is carried out, such as fruits and vegetables, for example, among others.

    The novelty of the invention focuses on the use of means for filtering broths used for washing agricultural products, so that it is not necessary to discard so much water to the drainage network, even avoiding spillage .

    In line with what has been said in the previous paragraph, the invention comprises a first continuous filtering medium that operates in parallel to the washing process of agricultural products 20, and a second filtering medium for the recovery of liquid that normally acts in downtime, although there is also the possibility that both filtering means, first and second, work simultaneously if necessary, thus achieving in this case a saving of time and therefore greater performance.
     25
    Therefore, an object of the invention are means for being able to carry out a continuous purification of the broths during the process of washing agricultural products and also means of the invention are means for recovering liquid from the broths used in washing, emphasizing that the liquid recovery process can be carried out simultaneously to the washing process, and also independently.

    BACKGROUND OF THE INVENTION

    Different systems for the treatment of products are currently known 35
    agricultural as described in the Technological Report with reference P5854, which cites, among others, three documents with publication number: CN 20072092082Y (D01), US 5783096 (D02) and DE 4428878 (D03).

    Document D01 refers to a wheat washing system 1 whose output is driven 2 5 to perform a centrifugal separation in a hydrocyclone 3 to separate in a stream the densest fraction in which the grain is collected. The current output with the shell is conducted to a filter 4 and the current with the grain is conducted to a sedimentation tank 5, both in order to recover the water and recycle it to the washing stage 1 by pumping means 6 , 7. 10

    Document D02 refers to an installation for recovering sugar beet particles that could be in the beet wash water. The washing water that may contain sand together with the beet particles to be recovered is driven 2 towards two hydrocyclones 5 in parallel, separating a denser stream with the sand 6 and another lighter stream with the beet particles 7. The heaviest fraction is passed again by another hydrocyclone 11 that performs a new separation recovering another small fraction of beet separated from the current that contains the sand.
     twenty
    Document D03 refers to a vegetable washing device in which water is recovered through a channel 4 since the vegetables are transported by an endless belt 2 that acts as a filter.

    It is also known the invention patent with application number in Spain P 200930841 25 referred to a recovery system for the treatment of harvested products, where the broths come from an installation 2 in which the treatment of harvested products takes place, of so that the broth is pumped into a filter-press 8 in which the filtering and corresponding dehydration of the broth takes place from where the broth is sent to a clarification tank 17 to which 30 disinfectant is injected from a dosing container 18 for disposal of spores, said broth being clarified and disinfected by recirculating again to installation 2, after injection of phytosanitary products by means of a dosing device.

    DESCRIPTION OF THE INVENTION

    The optimization system for the treatment broths in post-harvest processes that constitutes the object of the invention is applicable to an installation in which the treatment of agricultural products takes place by means of a shower device that projects clean broths in the form of rain. on agricultural products, so that said clean broths integrate water among their elements in combination with phytosanitary substances; where after applying the clean broths on agricultural products, dirty broths are generated that fall by gravity into a receiving raft; counting the system with a dosing device for phytosanitary substances and with a filtering medium that cleans the dirty broths to recover clean water.

    The system of the invention further comprises a first means of continuous filtration with hydrocyclone after washing of agricultural products, which operates in parallel during the process of washing agricultural products themselves; where the dirty broths collected in the receiving tray are driven through a first circuit that flows into the shower device, previously passing through the hydrocyclone that cleans the dirty broths and which is interspersed in that first circuit.
     twenty
    It also comprises a second discontinuous filtering means that integrates a band filter between its elements; recovering this second means of filtering clean water from the dirty broths; where the dirty broths collected in the receiving tray are driven through a second circuit that flows into the receiving raft itself; incorporating that second circuit at least the band filter. 25

    This second filtering medium can also be realized by other conventional filtering elements that already exist, or are developed in the future, and that are proven to be as effective or more than the band filter.
      30
    The second circuit integrates a dirty water tank, a clean water tank, a previous filter, a second drive pump and the band filter; where the dirty broths coming from the receiving tray are collected inside the dirty water tank and then passed to the previous filter, after which the second drive pump that pumps the flow of the liquid fluid to the band filter is located, for 35
    finally reaching the clean water tank, whose contents are drained to the receiving basin by previously opening a drain solenoid valve inserted in a terminal section of the second circuit.

    At the outlet of the dirty water tank there is a lower opening and closing solenoid valve, whose opening releases the exit of said dirty water tank to carry out the cleaning of the dirty broths through the previous filter and band filter in order to recover the clean water inside the clean water tank.

    The dosing device provides the phytosanitary substance to the liquid fluid contained within the clean water tank and also to the inside of the receiving raft by means of a first pipe and a second pipe, respectively.

    The first circuit and the second circuit share a common section of pipe in which a first drive pump is intercalated, so that in an area of 15 confluence, that common section of pipe branches into two branches: a first branch that is continuation of an entrance duct to the hydrocyclone, and a second branch that is part of the second circuit. In the first branch a first solenoid valve is inserted, and in the second branch a second solenoid valve is inserted, the two being able to adopt a closed position and an open position. twenty

     In a first option, only the process of washing agricultural products is operated, in this case the first solenoid valve is open and the second solenoid valve is closed.
     25
    In a second option, only the clean water recovery and cleaning process is operated, in this case the first solenoid valve is closed and the second solenoid valve is open.

    In a third option both processes are activated simultaneously in which both 30 solenoid valves: first and second are open.

    It is therefore a question of carrying out a cleaning and sanitizing of the broths of the installation (drencher) in order to extend its life and reduce the spills to be purified and managed.
     35
    The cleaning of the broths is carried out by means of the continuous recirculation of the broths of the receiving raft through the hydrocyclone that will retain a large part of the suspended solids and sedimentable matter. Purges are automatically carried out of the sludges retained in the hydrocyclone to deposit them in their storage tank. The supernatant of these sludges is managed or recovered to the receiving raft. 5

    The sanitation of the broths is carried out automatically and proportionally to the volume of water (with phytosanitary substance) that is replenished after the bathing of each pallet of agricultural products. This disinfection consists of the referred chemical treatment based on the phytosanitary substance (biocide) that is harmless after the reaction, but of high efficacy to eliminate the microbial load and reduce the contamination of the broths.

    Next, in order to facilitate a better understanding of this descriptive report and forming an integral part thereof, a single figure is attached in which the object of the invention has been illustrated with an illustrative and non-limiting nature.

    DESCRIPTION OF AN EXAMPLE OF EMBODIMENT OF THE INVENTION

    Considering the numbering adopted in the figures, the optimization system of the 25 treatment broths in post-harvest processes is applicable to an installation (drain) in which the treatment of agricultural products takes place by means of a shower device (1) that projects in the form of rain clean broths on agricultural products, so that these broths integrate water and phytosanitary substances.
     30
    After applying the clean broths on the agricultural products, dirty broths are generated that fall by gravity into a receiver raft (2), so that the dirt from the agricultural products passes the broths.

    Starting from this premise, the invention comprises a first means of filtering in
    continuous with hydrocyclone (3) after the washing of agricultural products, which operates in parallel during the process of washing agricultural products; and a second discontinuous filtering means that integrates between its elements a band filter (4), where this second filtering means has the mission of recovering clean water from the dirty broths while acting normally in the dead times 5 when the first filter medium is deactivated and the washing process interrupted; although there is also the possibility that both filtering means, first and second, work simultaneously if necessary, thus achieving in this case a saving of time and therefore greater performance.
     10
    The invention is complemented by a dosing device (5) of a phytosanitary substance on the broths and / or clean water; and with means to recycle the wash water to incorporate it again successively into the receiving raft (2).

    During the washing of agricultural products, the broth contained within the receiving raft 15 (2) is driven by a first pump (6) to the hydrocyclone (3) intercalated in a first circuit that flows into the shower device (1) which projects the broths in the form of rain on agricultural products, so that the hydrocyclone (3) is intercalated in that first circuit, the hydrocyclone (3) having an inlet duct (7), an upper outlet duct (8) which connects with the shower device (1), and a lower outlet duct (9) through which sludges from the broths that are collected in a previous tray (10) flow.

    In order to carry out the recovery of the clean water, the broth contained within the receiving raft (2) is driven to a second circuit in which the cleaning of the broth is carried out and which flows into the receiving raft itself (2), so that this second circuit integrates a dirty water tank (11), a clean water tank (12), an additional filter (13), a second drive pump (14) and the band filter (4).

     In line with what was said in the previous paragraph, the broth from the receiving tray (2) 30 is collected inside the dirty water tank (11) and then passed to the additional filter (13), after which the second one is located discharge pump (14) that pumps the flow of the liquid fluid to the band filter (4), to finally reach the clean water tank (12), whose contents are drained to the receiving pool (2) by previously opening a solenoid valve drain (15) interspersed in a terminal section of 35
    second circuit At the outlet of the dirty water tank (11) there is a lower opening and closing solenoid valve (16), whose opening releases the exit of said dirty water tank (11) to carry out the cleaning of the dirty water through the filter additional (13) and band filter (4).
     5
    This band filter (4) incorporates a lower conduit (17) in which a third drive pump (18) is interleaved to collect in a rear tray (19) the sludge retained by said band filter (4). In turn, the additional filter (13) retains the larger particles.
     10
    The dosing device (5) provides the phytosanitary substance to the water contained within the clean water tank (12) and also inside the receiving raft (2) by means of a first pipe (20) and a second pipe (21), respectively.

    In the embodiment shown in the only figure 1, the first circuit and the second circuit share a common section of pipe (22) in which the first drive pump (6) is intercalated, so that in a zone of confluence, that common section of pipe (22) branches into two branches: a first branch (23) that is a continuation of the inlet duct (7) to the hydrocyclone (3), and a second branch (24) that extends until it flows in the dirty water tank (11). twenty

    In the first branch (23) a first solenoid valve (25) is sandwiched, and in the second branch (24) a second solenoid valve (26) is sandwiched, the two being able to adopt a closed position and an open position, so that when it is Only the first solenoid valve (25) is open and the second one (26) closed, while the only cleaning process and water recovery is in operation when dirty broths circulate through the second circuit, the first solenoid valve (25) is closed and the second one (26) open.

    However, when both processes are active simultaneously, the two electrovalves (25) and (26) are open.
