Tobacco sheet stem powder raw material pretreatment mixing and stirring device

Abstract

The invention relates to a tobacco sheet stem powder raw material pretreatment mixing and stirring device which is a device for blending and stirring the prepared dry materials to be uniformly mixed before tobacco sheet stem powder raw materials are leached, belonging to the technical field of tobacco machinery. The device is mainly characterized by comprising a vertical mixing spiral shaft arranged in a tank body, a reducing motor outside the tank body, a feeding and discharging material level detector on the tank body, and a frame, wherein the reducing motor fixed on the frame drives a spindle in the vertical mixing spiral shaft; when the tobacco sheet stem powder raw materials are mixed, the tobacco stems and tobacco powder are vertically conveyed to the upper part of the tank through the vertical mixing spiral shaft, the materials are thrown to the periphery through the effects of spiral stirring blades which extend outwards and a throwing hopper, and the materials drop along the interior of the tank. When sliding to the bottom of the tank body, the tobacco stems and tobacco powder are lifted upwards by the vertical mixing spiral shaft again. The tobacco stems and tobacco powder are repeatedly recycled until the materials are uniformly mixed. The device is simple in structure and convenient to operate, and the batching uniformity can be met.

Description

technical field [0001] The invention relates to a mixing and stirring device for the pretreatment of tobacco sheet tobacco stem powder raw materials, which is a device for preparing and mixing dry materials of tobacco sheet tobacco stem powder raw materials before leaching to achieve uniform mixing , belongs to the technical field of tobacco machinery. Background technique [0002] In the production process of reconstituted tobacco sheet by papermaking method, raw material pretreatment is to pre-mix the formula raw materials to a certain extent to ensure the internal chemical composition stability of raw materials, and the uniformity and consistency of raw material feeding between batches. In the previous production of tobacco flakes, the pretreatment of raw materials was mixed by transporting raw materials from different origins, batches, and dates according to the formula requirements to the formula storage cabinet for layer-by-layer distribution and mixing. Therefore...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a kind of pretreatment mixing and agitating device for raw materials of thin tobacco stems, which solves the above-mentioned many shortcomings in the existing formula storage cabinets for layer-by-layer distribution and mixing of interlayers. It is required to prepare single tobacco stems or shredded tobacco chips and tobacco powder raw materials from different origins, different batches, and different dates, so that the raw materials of tobacco stems and tobacco powder can meet the uniformity of ingredients
