Leaf storage cabinet

Abstract

The invention provides a leaf storage cabinet. The cabinet comprises a cabinet body, at least one first air supply pipe, connecting pipes and a temperature and humidity detector. A first air outlet isformed in each first air supply pipe, an included angle is formed between the air outlet direction of each first air outlet and the inner wall where the corresponding first air supply pipe is installed, and outgoing air is suitable for forming an air curtain above materials in the cabinet body so as to isolate the external environment and avoid heat and humidity exchange with the external environment. A row of microporous air ports are formed in each first air supply pipe, the microporous air ports blow modulated air-conditioning air towards materials below the air curtain, and the hole diameters of the microporous air ports are increased along with increase of the distance between the microporous air ports and the connecting ends, connected with the first air supply pipes, of the connecting pipes. Through variable-diameter arrangement of the air ports, the air outlet amount of the air ports far away from the connecting ends is guaranteed, and the air amount in the cabinet body is more uniform. The first air supply pipes are directly arranged in the cabinet body, so that the temperature and humidity of materials in the cabinet body are more directly and stably controlled.

Description

technical field [0001] The invention belongs to the technical field of storage equipment, and in particular relates to a leaf storage cabinet. Background technique [0002] Tobacco is a substance that is very easy to absorb moisture and lose temperature and moisture in a short period of time. In order to ensure the processing quality of tobacco products and reduce shredding and tobacco dust, 18-21% is generally used in the leaf and leaf shred treatment process of the cigarette shred production line. High moisture content. At present, the silk production line of Chinese tobacco manufacturing enterprises generally adopts the design of fully air-conditioned environment-controlled leaf storage room, and the temperature required by 2.8.3 "Environmental Conditions" of the 2016 "Cigarette Process Specification" is 35-40±2°C. The relative humidity is controlled at 70±5%. [0003] There are multiple groups of leaf storage cabinets arranged in the leaf storage room, which are used f...

AI Technical Summary

Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is that the overall temperature and humidity stratification in the existing leaf storage room is serious, and the material temperature and humidity in each leaf storage cabinet cannot be guaranteed.
