Development of technology for the hemp stalks preparation

Abstract


Getting high-quality trusts in modern technology for growing technical hemp is one of the most labor-intensive processes.

The main factors that cause loss of quality of hemp are determined by the level of perfection of the harvesting stage of the production process. It is precisely at this stage that the basic processes of product quality management are concentrated, the main physical and technological losses are taking place.

The main drawbacks of the known methods of obtaining the trusts of technical hemp include the dependence of the process of forming its qualitative indicators on weather conditions, the unevenness of the separation and strength of the fiber on the entire mass of the sent layer, the length of the technological process, which determines the quantitative loss of production.

The article presents the results of research on the development of resource-saving technology for the production of technical hemp trusts due to the addition of an outlet with improved water drains with reeds and finger-wheels and the direct effect of their constructive parameters on the quality indicators of the trust.

Mechanized technological processes are carried out thanks to the developed unit, which includes: a modernized corrugated water pump, hay rakes and a roll baler.

It was noted that an increase in the number of mechanical influences on the hemp strap ribbon leads to a corresponding decrease in its height and mass. The loosening process reduces the weight of the tape to 2.1 kg per linear meter. Under these conditions, the height of the windrow increases to 35.0 cm. Techniques for obtaining a hedge trustee make it possible to reduce the time of process implementation at the initial stages of its preparation for primary processing, intensifies the process of purification due to the additional mechanical drive with improved aggregates. The short fiber obtained from the hemp trust for the technology developed meets the existing requirements.
