Sampling device for energy-saving efficient threshing and redrying system

Abstract

The invention discloses a sampling device for an energy-saving efficient threshing and redrying system. The device comprises a movable support frame, wherein a lifting adjusting mechanism is mounted at an upper end of the movable support frame, a lifting connecting piece is connected to the lifting adjusting mechanism, a mounting cross rod is connected to the lifting connecting piece, and three groups of sampling structures are uniformly distributed at a lower end of the mounting cross rod; and a lifting mechanism connected with the sampling structure is mounted on the mounting cross rod. The device is reasonable in design and stable in structure, three parts can be sampled at the same time by using the device by one person, manpower is effectively saved, sampling point positions are the same, sampling is synchronous, and detection errors are greatly reduced.

Description

technical field [0001] The invention belongs to the field of tobacco product processing equipment, and in particular relates to a sampling device for an energy-saving and high-efficiency leaf threshing and redrying system. Background technique [0002] Tobacco leaf rebaking in the leaf threshing and rebaking process is an important process for tobacco leaves to transform from agricultural products to industrial production raw materials. It is a very important link in the overall tobacco processing. Its main purpose is to adjust the moisture content of tobacco leaves to prevent mildew, remove dust, The purpose of purifying aroma, killing insects and sterilizing bacteria, facilitating storage and fermentation, keeping the color of tobacco leaves bright and improving the quality of tobacco leaves. Leaf rebaking is mainly through the three processes of drying, cooling and rehydrating the leaves after threshing and separation, so that the moisture and temperature of the leaves ca...

AI Technical Summary

Problems solved by technology

Leaf rebaking is mainly through the three processes of drying, cooling and rehydrating the leaves after threshing and separation, so that the moisture and temperature of the leaves can reach the specified technical indicators. After the leaves are rebaked, the moisture control is too small, which will lead to Severely broken, the rate of large and medium pieces of the finished product is reduced, and the moisture control of the leaves after rebaking is too high, which will lead to local mildew of the finished leaves during storage. If the temperature of the leaves after rebaking is too high, the core temperature will be too high. In the storage process, it is easy to burn the buns and cause carbonization and deterioration, which will eventually reduce the quality of the finished product

The rebaking machine is equipped with a sampling room at the front and back of the cooling zone. There is a window for sampling operation on the side of the sampling room. The function of the sampling room is to observe whether the air flow in the cooling part is balanced and to observe the state of the material on the conveying net. Whether it is consistent with the feeding state, so as to facilitate the adjustment of the air volume of the circulating fan. The second is to take samples to detect the moisture and temperature of the dried tobacco sheets. At present, when sampling operations, it is necessary to manually hold the long-handled sampling cup on the conveyor belt network Along the width direction of the board, at least three parts of the left, middle, and right are sampled at the same time, which requires three people to cooperate at the same time, which wastes manpower. In addition, during the sampling process, there will be different sampling points and out-of-sync sampling, which will lead to detection The result error is large
