Description

Segmented baking machine for threshing and redrying

Technical Field

The utility model relates to a threshing and redrying equipment technical field in tobacco processing, concretely relates to threshing and redrying is with sectional type roast machine.

Background

In the redrying production and processing process generally adopted in China at present, the blade redrying machine comprises a feeding system, a transmission and conveying device, a drying section, a cooling section, a moisture regain section, a water vapor system and an electrical control system.

The domestic leaf redrying production process comprises the following steps: tobacco flakes after threshing and air separating are pumped to a blanking device through an air pipe, tobacco leaves are distributed to a leaf cabinet through a transverse straight carriage and stored, after the tobacco leaves are stored to a certain degree, the discharged tobacco leaves pass through a foreign matter removing machine and then enter a lower air inlet area of a leaf baking machine for drying, then enter an upper air inlet area of drying, then enter a cooling section for cooling, then enter a moisture regain area for moisture regain processing, enter a packaging link for packaging and boxing, and are sent to a tobacco shred making processing link.

The drying section of the existing baking machine is used for drying the leaves to the required moisture content. The drying section is divided into a lower air inlet part and an upper air inlet part. The lower air inlet part accounts for about 75% of the length of the drying section, and air moves upwards from the lower part of the material layer, so that the most main baking work is completed. Hot air required by drying is provided by a heat exchanger and a drying fan, an adjusting hood is arranged on an air guide ring of an air inlet of the fan and can adjust the air quantity, an air guide screen plate is arranged in a drying chamber, and an adjusting plate is arranged at the narrow end of the air guide screen plate and can adjust the air speed distribution of a screen surface. In the drying process, because the moisture evaporates, the relative humidity of air increases, consequently is equipped with the moisture system of arranging, gets rid of the higher air of partial water content, and the rethread shutter replenishes fresh air, gets into the drying chamber through the heat exchanger heating, and circulation so to guarantee the drying condition, prevent to produce the comdenstion water in the aircraft bonnet. The upper part of the lower air inlet part is provided with a baffle vane screen plate which has the function of preventing the air flow from being taken away and falling onto a heat exchanger, so that the ventilation resistance is increased, the drying air volume is reduced, and the drying speed is influenced. Once the majority of the tobacco leaves are dried in the first portion and the air passage resistance is not great, the upper air intake portion will primarily bake the uppermost surface of the tobacco leaf layer. The upper inlet portion forms a separate part with independent temperature and relative humidity regulation.

However, after the tobacco flake materials are subjected to threshing, large tobacco flakes, medium tobacco flakes and small tobacco flakes are mixed, in a drying section of a traditional leaf roasting machine, air can only be supplied through a fan and passes through an air guide screen plate, an adjusting plate at the narrow end of the air guide screen plate is arranged, the air speed distribution of the screen surface is adjusted, large, medium and small tobacco flakes are mixed together, the same hot air enters roasting, the large tobacco flakes are not roasted, the small tobacco flakes are too dried, the tobacco leaves which are not dried are easy to mildew and influence the quality and the quality of products, the dried tobacco flakes are easy to break and influence the taste of the products, and meanwhile, due to the different factors of modules, weights and proportions of the threshing and redrying production materials, the processing effect of the traditional leaf roasting machine is not ideal, and the effect is poor for threshing and redrying which require stable quality and efficient homogenization processing requirements.
