Abstract

This invention relates to agricultural equipment and can be used for post harvest. tobacco leaf processing. The purpose of the invention — an increase in the yield of tobacco — is achieved through the rational use of heat in the process of air exchange between languishing zones, drying the leaf plate, drying the vein and moistening the tobacco in the cells. 1 il.

WITH

The invention relates to agricultural equipment and can be used for post-harvest processing of tobacco leaves.

The purpose of the invention is to reduce tobacco

The drawing shows a functional diagram of the device for implementing the proposed method of post-harvest treatment of tobacco leaves.

The device consists of located - iK parallel cameras I and I; each of which is divided into four zones; languor (l) j drying sheet plate (

The device operates as follows:

 The tobacco in the bush ndah enters zone 1 of chambers I and II5 where leaves languish at 30–40 ° C and a relative humidity of 78–95% for 12 hours. “Then the tobacco leaves are fed to zones 2 of chambers I and II, where Over the next 12 hours, the plates are dried at 40–50 ° C and relative air humidity of 50–78%. At the same time, fresh tobacco is served in zones 1 of languor. After 12 hours, the tobacco is moved to the next zones of chambers I and II, i.e. from drying zones 2 —to the table are served in zones 3 of drying veins, and from zones 1 to zones 2 of drying B pastinio In zone 3, the roots of the veins are dried at 50-60 С and relative E | 20-30% over the next 12 h. Then tobacco again, and in zones 4, the tobacco is moistened at 25–30 ° C and relative humidity of 95–100%. After that unload,

In the process of languishing, with (ears of the plate, drying of the vein and moistening, mutual interchange of air between adjacent chamber chambers is actively used. Thus, in zone 1 of chamber 1, the tobacco languishing is produced, while in the adjacent zone 4 of chamber II 1 | It is humidified. Moist air from the languid zone enters the humidification zone. Similar air exchange, but in the opposite direction

direction occurs between zone 1 of chamber II and zone 4 of chamber I,

Air is also exchanged with area 3 (drying of the vein) of chamber I and zone 2 (plate drying) of chamber IIJ, zone 3 of chamber II and zone 2 of chamber 1 "

It is possible to transfer air from the languor zone or the plate drying zone to the tobacco wetting zone, as well as from the drying zone of the vein to the plate drying zone.

In addition to the described processing mode of tobacco leaves, a mode is also possible. In this process, each process (languishing, drying, drying and moistening) is carried out in all areas of the device simultaneously, i.e. the tobacco is fed into chamber I without being divided into zones. At the same time in all areas of the chamber support the same mode of heating tobacco. After 12 hours of tobacco languor change the temperature and humidity conditions in the chamber from the languor to the drying plate, and then the drying of the vein is carried out for the same time. Simultaneously with the last process, tobacco is placed in chamber II and spent languishing. In the future, with the same duration (12.h), processes are alternately carried out simultaneously in both chambers; in chamber I - moistening, in chamber II - drying of the plate, in chamber I - languishing, in chamber II - drying of the vein, in chamber I - drying of the plate, in chamber II - humidification and tod. Thus, the processes in chambers I and II are shifted in time into two stages. In this mode of operation of the device, the energy-intensive process in chamber I is combined with the low-power process in chamber II and vice versa.

The shift between processes in chambers I and II can also be in one or three stages.

The active use of air exchange between zones and chambers with various technological processes provides savings of heat and electric energy, which leads to the acceleration of the entire technological process of processing tobacco leaves and an increase in dry tobacco code.

Claims (1)

Invention Formula The method of post-harvest processing of tobacco leaves, providing alternately languishing, drying the leaf plate, drying the vein, moistening the tobacco, characterized in that, in order to increase the tobacco output, it is moistened using air coming from the languor zone, drying the leaf vein using air coming from the moistening zone and drying the plate sheet air coming from the zone. dosushki veins.
