Abstract

The invention relates to agricultural machinery, in particular to devices for treating fruits with protective solutions and cooling them before being put into storage. The purpose of the invention is to increase plant capacity while reducing energy consumption. The plant for treating fruits with solutions contains a roller conveyor, a solution tank with a sump and discharge hose, a centrifugal pump with a filter, and a shower device with curtains. New in the installation is the supply of the tank with an inclined tray installed in the tank for movement of impurities in the discharge zone, as well as the installation of cooling elements in the discharge line filter. This allows the sludge to be drained without stopping the process and reducing energy costs for cooling fruits. by eliminating pre-cooling of the solution. 3 il. about SS CO

Description

The invention relates to agricultural machinery, in particular, devices for treating fruits with protective solutions with their cooling before storage.

The purpose of the invention is to increase plant capacity while reducing energy consumption.

FIG. 1 shows the proposed installation, the general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

The installation contains a roller conveyor 1 with freely rotating | set rollers

fruit containers 2, shower device 3 with curtains 4 that prevent splashing and solution loss, a centrifugal pump 5 and a filter 6 in which the cooling elements 7 of the tank 8 are installed with a sump 9 and the drain sleeve 10. Inclined sump 11 for directional movement of the solution with impurities placed in the tank 8 with the formation of the chamber 12 for placing the solution free of impurities, while the chamber 12 communicates with the cavity of the tank 8 through the holes made in the upper part of the wall 13 of the chamber 12 placed before sediment

com 9, and the suction inlet of the centrifugal pump 5 with filter 6 is installed in the chamber 12 for the solution free of impurities.

The installation works as follows.

In the tank 8 pour pre-cooked solution. On the roller conveyor 1, containers 2 are mounted with a forked loader, and the promotion of containers 2 along the roller conveyor 1 is provided by pushing another container over the previous ones. Through the filter 6, the centrifugal pump 5 supplies the solution, cooled by cooling elements 7, from the bottom of the tank 8 to the openings of the shower device 3, through which the solution is sprayed onto the containers 2. The fruits are simultaneously washed, cooled and covered with a protective solution film washed away impurities through fruits, containers and curtains 4 flows into the upper part of tank 8. In the discharge zone, runoff of solution residues into tank 8 provides an inclined drip 1 ". On an inclined drip 11, impurities roll into a sump 9, accumulate here, and are subsequently removed with a portion of the solution through the drain hose 10 down the drain. The circulation of the solution is carried out through the holes in the wall 13. After removing the sludge, the level of the solution is adjusted to the desired level. The supply of the tank 8 with the pallet 11 allows the latter to be used as a coarse filter for the liquid by changing the flow direction in the zone of the settling tank, which is also introduced into the design of the tank

ara. In this case, the filter itself is used as a fine filter. Such a design allows the sludge to be drained without stopping the process. Placing the cooling elements directly in the filter avoids pre-cooling the entire volume of the liquid. As a result, the shift time utilization rate increases and, consequently, the productivity. Since energy is consumed to cool the liquid only in the pressure line, a positive result — sufficient cooling of the fruit — is achieved at a lower cost.
