Abstract

The invention relates to the field of agricultural engineering and can be used to clean the coriander. The purpose of the invention is to reduce the loss of coriander, improving the quality and performance of cleaning. The method is implemented on an installation consisting of pneumatic channels 1-3, collecting chambers 4-6, fans 7, 8, bunker a-feeder 9, sluice gate 10, a sieve mill 11, dust collector 12 and a grater apparatus with elastic layers 14 and 16. The grain mixture is pre-divided by air flow into two equal in weight coriander fractions, from which only the fraction with dodder is rubbed, and incompletely destroyed dashboard boxes from the rubbed material are separated by airflow and mixed with the fraction to be rubbed. Hard - x: elastic material of one of the grinding surfaces is 12-22 units of Shore A, and the hardness of the material of the adjacent surface is 65-80 units of Shore A. 3 Il.

FIELD OF THE INVENTION The invention relates to agricultural machinery and can be used in essential oil production for coriander gstha.

The purpose of the invention is to reduce the loss of coriander, improving the quality and performance of cleaning.

FIG. 1 shows a flow chart of an installation for carrying out the method of cleaning seed coriander, general view; in fig. 2 - distribution curves of coriander fruits and dodder boxes according to the speed of vitani; in fig. 3 - curves of probabilities of destruction of the fruits of coriander and dodder boxes depending on the length of the rubbing path.

The method of cleaning the coriander seed from the dodder is carried out at the plant, which consists of pneumatic channels 1-3, settling chambers 4-6, fans 7 and 8, feed hopper 9, sluice gate 10, sieve mill 11, dust collector 12 and drum grating apparatus, including the shaft 13, wrapped with a layer 14 of dense rubber and deck 15, covered with a layer 16 of elastic sponge rubber. Layer 14 of dense rubber has a hardness in the range from 65 to 80 units of Shore A, and layer 16 - from 12 to 22 units of Shore A.

The method of cleaning seed coriander from dodder is carried out as follows.

The coriander seed mixture and dodder from the feed bin 9 enters the pneumatic channel 1. The lower part of the pneumatic channel is a pneumatic conveyor and therefore the particles of the grain mixture are raised by air flow to the upper part, where the particles of a grain mixture having a soaring speed of more than 5.3 m / s are deposited in chamber 4, and the rest enter chamber 5. From chamber 4, the grain mixture passes through the lock gate 10 to the mining camp 11. From chamber 5, the grain mixture particles enter the grater apparatus, where they are ground between the surfaces of the deck and the drum. After grinding, the grain-mixture particles enter the permeable channel 2, where fine dust (remains of the shells of poviliki boxes) and incompletely destroyed povilis are released by air riOTOKOM. The isolated material of the pneumatic canal 2 of the pneumatic canal 2 is inserted into the os4.4.1, chamber 5, where incompletely destroyed dodder boxes are deposited and mixed with the light fraction of the raw material, which is used for grinding, and fine dust is carried out of the chamber 5 through the air flow through the fan 7 into dust collector 12. Particles of the grain mixture, which have been milled and cleaned in pneumatic channel 2, are fed to the Mill P, where sifting of small particles of the grain mixture occurs, which include seed seeds of crushed bolls and Coriander luplodic. The descent from the sieve mill 11, consisting of peeled coriander fruits, undergoes additional pneumatic cleaning in channel 3 and enters the

2 exit 17, and waste in exit 18.

Experiments show that to completely separate the bolls of the dodder, the separation of the grain mixture should be carried out by air flow at a speed of 5.6 m / s. at the same time, half of the coriander fruit should go to the light fraction together with the dodder boxes (Fig. 2).

With more favorable cases for the distribution of the bolls of dodder and coriander fruit, the distribution curves

. they are more distant from each other (Fig. 2) and therefore the complete selection of dodder boxes is accompanied by a somewhat smaller separation of coriander fruits.

Experimental studies (this refers to the expediency of using materials with a hardness of 12 to 22 units of H. O. A. And the hardness of the material of the adjacent surface is from 65 to 80 units of Shor A.
