Development of new method of placing tobacco leaves for improve the technology of post-harvest processing of tobacco
The analysis of the impact of the type of placing tobacco leaves on the efficiency of drying is conducted. It is shown that the length and quality of drying leaves, energy and labor costs are closely associated with the physical condition of the tobacco mass and individual leaves in the conduct of production processes for handling, transport, storage. Type of placing is responsible for the success of the transport work and storage, and the method of drying the placing tobacco is responsible for the technology of this process. In All-Russian scientific research institute of tobacco, makhorka and tobacco products studies on the development of new technologies, equipment and work organization in the post-harvest processing of tobacco, in which the drying of tobacco leaves is the main technological process. Experiments were carried out with the use of new types of placing tobacco leaves, where the main element is a twin double-sided needle. Presents the procedure for placing the leaves using a new set of devices in the technology of post-harvest processing of tobacco. The stages of placing include: the formation of bundles of leaves at harvest; stringing the bundles of leaves on the twin double-sided needle; placement of the twin double-sided needle on hanger for double sided needles; the formation of the party consisting of several hangers for drying leaves in natural or artificial conditions; sealing the tobacco mass on the hanger in 2-2,5 times on account of twin double-sided needles to conduct completing of drying fibres and subsequent wetting of leaves; placing of dried tobacco into bales for temporary storage with a hydraulic press.
