SUBSTANCE: machine has bed, container for washing solution, conveyor, washing brush, drive and transmission system for moving conveyor and washing brush, water supply system for supplying water to conveyor, drying system, feeding and discharge trays, with said parts of machine being mounted on bed. Conveyor is made in the form of immovable cylindrical screw and guiding cylinder concentrically located within cylindrical screw. Washing brush is located concentrically within guiding cylinder on single shaft for rotating of washing brush and guiding cylinder at different velocities. Immovable cylindrical screw is formed as spiral, with space between coils of cylindrical screw providing retarding of eggs. Guiding cylinder is equipped with slots having size corresponding to that of eggs, said slots extending in parallel with axis of rotation.

EFFECT: reduced metal usage and power consumption, enhanced reliability in operation and improved quality of sanitary treatment of eggs.

Description

The invention relates to the field of poultry and can be used for the sanitary processing of eggs in the egg warehouses of poultry farms, in the melange workshops of poultry plants and in confectionery factories.

Known egg washing installation YAMU-F-10A, including a six-row roller conveyor, feeding eggs under the brush, which, making reciprocating movements in a vertical plane, cleans the eggs. Eggs are wetted through nozzles mounted motionless above the brush block. The cleaning solution is piped through the pump. (Technical description and operating instructions for NMU-F-10A. TO Ufa Agricultural Engineering Plant, Ufa, 1988).

The disadvantage of the installation is that the design of the brush mechanism allows only reciprocating movement of the brushes relative to the object being cleaned, which leads to the formation of holes in the pile, which in turn leads to a decrease in the quality of cleaning, to an increase in egg breakage and frequent brush changes.

Closest to the claimed technical essence and the achieved result is an egg sanitizing machine containing a roller conveyor located above the conveyor and rigidly mounted on one shaft with the possibility of rotation in the horizontal plane of the brush mechanism made of two or more coaxially intersecting pairs of cylindrical brushes, and an irrigation device containing nozzles located above the brushes, a main container for washing solution, a fan for drying (RF Patent No. 2202880, Bull. No. 12, 2 04/07/03).

The disadvantage of this machine is the complexity of the design, high weight, the complexity of manufacturing.

The proposed invention solves the problem of reducing material consumption and energy consumption, increasing the operational reliability of the machine with appropriate quality.

To achieve a technical result in an egg sanitizing machine containing a bed, a washing solution tank mounted on it, a conveyor, a washing brush, a drive and a transmission system to ensure the movement of the conveyor and the washing brush, a water supply system to the conveyor, a drying system, and outlet trays, the conveyor is made in the form of a fixed cylindrical screw and a concentrically guiding cylinder located inside it, the washing brush is located concentrically inside the guiding cylinder with respect to it on a common axis with the possibility of rotation of it and the guide cylinder at different speeds, while the stationary cylindrical screw is made in the form of a spiral, the step of which corresponds to the size of the egg, and the guide cylinder contains slots with a width corresponding to the size of the egg, and directed parallel to the axis of rotation .

The invention is illustrated by drawings, where

figure 1 shows the proposed machine, front view;

figure 2 is a top view.

The egg sanitation machine consists of a bed 1, a container 2 for washing solution, a filter 3, a heater 4, a pump 5, a protective casing 6, a drive 7, a brush 8, an electric air heater 9, and a conveyor consisting of a fixed cylindrical screw 10 and located inside a concentric guide cylinder 11. To supply the washing solution from the tank 2 to the conveyor, a pipe is arranged 12. The flow of water through the openings of the pipe in the washing zone 13 is indicated by arrows 14, the flow of hot air in the drying zone 15 is indicated by arrows s 16. The brush 8 is rigidly secured to axle 17 which rotates in bearings 18, the guide cylinder 11 rotates in the bearings 19. Thus, the brush 8 and the guide cylinder 11 can be rotated on the same axis at a different rate. For the rotation of the brush 8, a pair of pulleys 20 with a belt drive 21. For rotation of the guide cylinder 11, two pairs of gears 22 and 23 are used with chain transmissions 24 and 25. The fixed cylindrical screw 10 is fixed rigidly to the frame 1 using connections 26. Eggs for washing come to the fixed cylindrical screw 10 along the supply tray-slide 27, and exit the receiving tray-slide 28. To drain the washing solution from the tank 2, a tap 29 is used. In the guide cylinder 11, longitudinal grooves 30 are made parallel to the generatrix of the cylinder. The width of the grooves 30 should provide free passage of the egg, and the distance between the turns of the spiral of the screw 10 should hold the egg (except for the joints with the tray-slides 27 and 28). Thus, the egg 31 through the longitudinal grooves 30 with a brush 8 is pressed against the spiral of the screw 10.

Machine for sanitary processing of eggs is as follows.

The egg enters (feeds) through the slide tray 27 into the longitudinal groove 30 of the guide cylinder 11, rotating at a speed of ~ 30 rpm, while rotating the egg at a speed of ~ 500 rpm inside the guide cylinder, the brush 8 is pressed against the inner surface of the screw spiral 10 and forcibly rolled along the inner helical surface of the spiral, being in the longitudinal groove of the guide cylinder 11.

In this case, the egg makes a complex movement:

1) rolling along the inner surface of the spiral, rotates around its axis;

2) rotates along the internal helix of the screw spiral 10;

3) performs translational movement along the longitudinal groove 30 of the rotating guide cylinder horizontally.

First, the egg is subjected to comprehensive cleaning with a rotating brush 8, while washing it and the brush with a heated detergent solution in zone 13. Upon further passage through the conveyor, the egg enters the drying zone 15 by a stream of heated air from an air electric heater (air heater) 9. Then, leaving the zone of operation of the spiral conveyor, an egg from the groove 30 of the rotating guide cylinder 11, under the action of its own weight, is fed to the receiving table by means of its own slip tray 28 for further processing of the equipment (marking, weighing I, calibration, packing in containers, etc.).

The proposed machine for the processing of eggs has high performance. Thus, the economic effect of the proposed machine for washing eggs is due to a decrease in material consumption (total weight is 3-5 times less than in the prototype), energy consumption and, accordingly, lower production and operation costs with the corresponding quality of egg washing.
