Abstract

The main indicators characterizing the quality of etching are the completeness of etching and the degree of coating of the surface of the seeds with the preparation. It is also important to reduce mechanical damage to seeds and drug consumption, eliminate harmful effects on humans and the environment. Currently, the etching of cotton seeds with chemical preparations is carried out centrally in specialized seed preparation workshops at cotton gins. This article presents the data of the studies carried out as a result of which a new design of a pickler of pubescent and bare seeds with a hexagonal mixing drum was developed and manufactured. The subsequent free movement of the seed under the influence of gravity with an initial velocity directed at an angle to the horizon along the inclined tray of the etcher is considered after several strokes, the equation determining the kinetic and potential energies of the rolling seed on an inclined surface is derived. The results of experimental studies conducted on the manufactured pickling of pubescent and bare seeds are also presented.
