Abstract

The invention relates to the food industry. The purpose of the invention is to increase the productivity and quality of cleaning vegetables. The vegetables to be cleaned, moving in the sleeve within the flow of foreign abrasive bodies, move along a closed path due to helical vibrations, and simultaneously interact with surfaces of different abrasive shapes and sizes. The ratio of the minimum size of vegetables to the size of abrasive bodies is (1: 0.25) - (1: 0.5). The vegetables to be cleaned due to the components of the screw oscillations with a frequency of 20-25 Hz, amplitude of 0.003-0.005 m and the angle of inclination of the vibration direction relative to the vibrating table 12-45 ° are rotated in two mutually perpendicular planes, which greatly intensifies the process of abrading the peel. 2 sec. and 2 z. p. f-ly, 1 ill.

Description

The invention relates to the food industry and can be used in public catering and other industries related to the processing of vegetables.

The aim of the invention is to increase the productivity and quality of peeling vegetables.

FIG. 1 schematically shows a device for carrying out the method of peeling vegetables.

The device contains a vibrating table 1 mounted on springs 2 and driven in an oscillatory motion along a helical path by a vibrator 3. On the vibrating table I, a working chamber 4 is installed, made in the form of an annular groove, inside which a sleeve 5 is placed along its entire length connecting the unloading nozzle 6 of the working chambers 4 and the outlet of the loading hopper 7 installed above the working body along its central axis on vertical guides 8. Above the working chamber 4 along its entire length a shower device 9 is installed, and under whose chamber 4 is an annular collector 10 with an outlet II for pulp and used water. The sleeve 5 is made of rods 12, curved along a helical trajectory. The discharge pipe 6 is above the lower level of the gutter for removal of the peeled vegetables without abrasive bodies.

In addition, the hopper 7 is mounted on vertical guides 8 with the possibility of vertical movement relative to the working chamber.

The method of peeling vegetables is carried out as follows.

Calibrated vegetables (beets, radish, potatoes, etc.) are loaded into a hopper 7 mounted on vertical guides 8 connected to a vibrating table 1 supported by springs 2. Under the action of helical vibrations created by the vibrator 3, vegetables come from the outlet of the bunker 7 into a n-coal sleeve 5. Then, under the action of .m. vertical components of helical oscillations, as well as the actual weight of the vegetable column in the ring

The working chamber 4 inside the stream of abrasive bodies along the annular groove of their abrasive bodies simultaneously interacts with surfaces of abrasives of various shapes and sizes. As a result of intensive abrasion of the rind with abrasives 0, the vegetables are cleaned with simultaneous rinsing of the rind with water with the help of the perfuming device 9 and removal through the perforation of the trough of the working chamber 4

parts of the sleeve 5, raised above the working chamber 4, and the vertical component of the helical vibrations.

To increase the quality of cleaning vegetables and intensify the process of rubbing their skin, and also to move the entire flow through the annular chute, it is advisable to carry out the vibration process along a helical trajectory with an oscillation frequency of 20-25 Hz with an amplitude of 0.003-0.005 mn followed by entering the ring the angle of inclination of the vibration direction, relative collection 10, and through the output vibration table 1 from 12 to 45 °. pipe 11 - in the sump. PurifiedAlso, high quality cleaning

It is provided at a ratio of the minimum size of vegetables to the size of abrasive bodies from 1: 0.25 to 1: 0.5 by eliminating excessive wear of the vegetables and the loss of their presentation.

The proposed method and apparatus for cleaning vegetables allows for a continuous cleaning process with high quality cleaning.

Claims (4)

1. The method of peeling vegetables by interacting with abrasive bodies while irrigating at the same time horizontal circular and vertical linear oscillations, different in the radial direction of the points of the annular trough of the working body 4 are different in amplitude and direction in order to increase productivity and quality of cleaning, abrasive bodies are moved due to oscillations along a circular trajectory in a horizontal plane and straight lines - in a vertical plane, with fluctuations, therefore, abrasive bodies, which are located in this movement of vegetables, are made closer or farther from the vertical through the center of the flow of abrasive bodies over the axes of the vibrating table 1 will have a lower or greater proper relative speed of movement. This velocity difference across the cross section of the groove, created by the component of horizontal circular oscillations, causes the vegetables to rotate in a horizontal plane. On the other hand, vibrations from the bottom of the chute are transmitted to the lower layer of abrasive bodies, and 40 helical path. 2.
