Organization of the technological process of hemp treatment processing with chaotic arrangement of stems at the hemp plant

Abstract

The aim is to study the possibilities of processing hemp with a chaotic arrangement of stems on the technological equipment of a hemp plant, to determine the quality indicators of the produced fiber. A brief description of the work performed. The technological processes of processing hemp with a chaotic arrangement of stems on the equipment of hemp growers with the separation of the fiber into long and short and its receipt in the total mass were studied. It was established that during the processing of this raw material on a milling and heating unit, the produced long fiber has a low yield of 6 to 11%, depending on the characteristics of the trust in a roll with its length from 110 to 160 cm. Its production is carried out with frequent stops of the technological process with the reasons why a significant part of the stems do not fall under the clamp of the transporting conveyor, which cause clogging of the pneumatic conveying system. At the same time, about two-thirds or more of the total mass is short fiber. With such obtained indicators, the production of a long fiber from a trust with a chaotic arrangement of stems is impractical. When producing hemp fiber in the total mass on the equipment of the hemp grower, the gear-type ball forming mechanism is excluded from the technological process, and the raw material after passing is transferred to the short fiber line by the pneumatic transport system through the inspection window of the first section of the heating drums when they are turned off. The produced fiber in total weight can mostly correspond to the second or third grade depending on its breaking load. Conclusions. The possibilities of processing hemp with a chaotic arrangement of stems on the technological equipment of the hemp plant and indicators of the quality of the produced fiber are determined.
