Abstract.
 The article provides information 
on the post-harvest processing of cereal and seeds of 
leguminous crops, which takes an important place in ensuring the safety of the crop and 
bringing it to marketable condition, as well as in the preparation of high-quality seed material. 
The t
echnical solution and information presented
 on the design and principle of operation of an 
experimental model of an energy and resource-saving device for cleaning seeds of cereals and 
leguminous crops from various impurities and weed seeds by separating them into fractions 
using an air flow. An experimental sample of the device was made according to the developed 
design documentation. Experimental studies on cleaning seeds of cereal and leguminous crops 
from various impurities and seeds of weeds were carried out on an experimental model of the 
device. Experimental studies have found that when cleaning wheat seeds, the cleaning efficiency 
from various impurities and weed seeds, respectively, is 98.0 and 96.0%, and when cleaning 
mung bean seeds, respectively, it is 100.0 and 98,0 %. 
 
Keywords
: seeds of cereals, seeds of leguminous crops, energy and resource-saving device,

INTRODUCTION. 
Cleaning grain and seeds of agricultural crops from impurities is the 
most important method in processing grain and seeds, significantly affecting the stability of the 
quality of their storage; improving the quality of consignments of grain and seeds of agricultural 
crops transferred for processing; increasing the efficiency and productivity of technological
