Problems solved by technology

The demand for burley tobacco dryers in major domestic tobacco factories mostly depends on imports, the import price is high, and it is not suitable for the market of domestic tobacco factories. In terms of the performance of the equipment, the fan is arranged on the side, which requires a special drying side room and humidification. Side chamber, which makes the structure of the machine complex and bulky, and because of the side air intake, the wind parameters of the tobacco leaves and the temperature of the discharge are not uniform
It is not conducive to accurate control of tobacco leaf processing process parameters

Embodiment Construction

[0009] See attached figure 1 A in the figure is the spreading device, B is the drying section, which is composed of several drying chambers, C is the cooling section, and D is the dampening section, which is composed of several dampening chambers. The tobacco leaves are evenly laid on the mesh belt by the laying device A, and the setting process is carried out through the drying section B, the cooling section C and the dampening section D sequentially with the movement of the mesh belt. The spreading device (see attached figure 2 ) adopts a variable speed belt conveyor 13, a variable speed flat-push scraper 9 and a group of laying rake rollers 14 to work in coordination. The scraper 9 is driven by a timing belt 8, a timing pulley 11 and a double-speed reducer 12. The scraper The swing is controlled by cylinder 10. When the tobacco leaves are continuously conveyed forward by the variable speed belt conveyor 13, the scraper 9 is dragged by the synchronous belt 8 to do a recip...

Abstract

A dryer is set with fan and air heater or air humidifier symmetrically at top and bottom position of net belt to make hot air or wet air directly form circulation at top and bottom of material layer in box based on existing machine so no need of drying side chamber and humidifying side chamber.

Description

technical field [0001] The patent relates to a burley tobacco dryer, in particular to a symmetrical burley tobacco dryer with uniform wind parameters and uniform discharge temperature, which is conducive to accurate control of the tobacco leaf treatment process. It belongs to the field of tobacco machinery. Background technique [0002] The existing burley tobacco dryer is mainly composed of a material spreading device, a drying section, a cooling section and a dampening section. A drying side room is arranged next to the drying room of the drying section, and an air heater and a fan are arranged in the drying side room; There is a humidification side room next to the moisture recovery room, and the humidification side room is equipped with an air humidifier and a fan; the burley tobacco leaves are evenly laid on the mesh belt by the laying device, and the mesh belt moves through the drying section, cooling section and Resurrection section for process treatment. The demand...
