SU1183010A1 - Method of postharvest treatment of seeds - Google Patents

Abstract

1. A method for post-harvesting of seed treatment, including temporary preservation, two-stage drying, cleaning and storing, characterized in that, in order to improve processing quality while reducing energy consumption, the seeds after the first stage of drying are divided into dry, wet and raw, then the raw seeds are returned to the first stage of drying, the wet ones are sent to the second stage of drying, cleaning and storage, and the dry ones - to cleaning and storage. 2. A method according to claim 1, characterized in that the separation by humidity is carried out in an electric field.

oo

The invention relates to agriculture, in particular to technological processes of seed treatment, mainly grain crops.

The purpose of the invention is to improve the quality of processing while reducing energy consumption.

The drawing shows the scheme by which the proposed method is carried out.

The diagram shows the following operations: 1 - reception of seeds; 2 - temporary preservation, 3 - the first stage of the tree, 4 - separation of seeds into dry, wet and raw, 5 - the second stage of the tree, 6 - cleaning, 7 storage.

The post-harvest treatment of seeds takes place as follows.

Harvested seeds are received at reception 1 of it for temporary conservation 2, after which they pass the first stage of the tree 3. The seeds, dried in the first stage, are divided (4) into three streams — dry, wet and raw. The dried seeds are sent directly to the cleaning 6 and storage 7, wet to the second stage of drying 5, followed by cleaning 6 and storage 7. The raw seeds are recycled by the same steps as the temporary seeds that were preserved.

Technically, the proposed method can be carried out as follows.

Seeds brought from the floor go through a scoop of mu and noria to a pre-cleaning machine, for example, MPO-50, after which they are fed into active ventilation bins, for example, BV-40. Passing temporary conservation in ventilated bunkers, the seeds are fed to the substance in the shaft dryer SZSh-16, configured for consistent work of the mines. Having passed the first stage of drying in the first shaft, the seeds go to a moisture separator, for example, an electric separator, which, by means of an electric field, seeds are separated by moisture into three streams. Dry seeds from the mine to the second dryer shaft come to the seed cleaning line, including, for example, the ZVS-20 primary cleaning machine, the SVU-5 secondary cleaning machine and the BT-5 triyer block and then to the storage depot.

Wet seeds are fed to the dry stock in the second bed of the sushki, and raw seeds are returned to the first bed of the dryer.

Claims (2)

1. METHOD FOR POST-HARVESTING TREATMENT OF SEEDS, including temporary preservation, two-stage drying, cleaning and storage, characterized in that, in order to improve the quality of processing while reducing energy consumption, the seeds after the first stage of drying are divided into dry, wet and raw, after which raw seeds return to the first stage of drying, wet sent to the second stage of drying, cleaning and storage, and dry - for cleaning and storage. 2.
