Method and special device for implementing tobacco leaf product online cooling in threshing and re-drying production

Abstract

A method and special device for implementing tobacco leaf product online cooling in threshing and re-drying production are characterized in that a plastic sleeve film packaging box with cigarette blanks is pre-pressed and re-weighed, and enters to a packaging process; vacuum-pumping treatment is performed on the cigarette blanks in the plastic sleeve film packaging box while packaging, the temperature of a cigarette packet is decreased, and a gap between the cigarette blanks and the plastic sleeve film is removed; when the system performs vacuum pumping and a preset temperature is reached, a temperature sensor feeds information back to the system, the system stops vacuum pumping, a pressing head raises, and the cigarette blanks move along a roller channel and enter a sealing process. The packaging machine has a vacuum pumping function, the air pressure in the cigarette blanks is reduced through vacuum pumping, the water boiling point is decreased, water in the cigarette blanks are evaporated, heat is brought away, the products are cooled, and then a packet cooling process can be canceled. The method can balance product water; the air pressure in the sleeve film is reduced through vacuum pumping; the gap between the cigarette blanks and the plastic sleeve film is automatically eliminated; moisture condensation on the inner wall of the sleeve film can be avoided; mildew of the cigarette blanks can be prevented; and the safety of the products can be ensured in storage and transportation.

Description

technical field [0001] The invention relates to reducing the temperature of leaf products in the process of threshing and redrying in the tobacco industry, in particular to a method and a special device for realizing online cooling of leaf products in the production of threshing and redrying. Pack temperature, balance leaf product moisture. Background technique [0002] In the threshing and redrying production of the tobacco industry, the temperature and moisture of the product leaves are very important process quality indicators, and their level directly affects the safety of the finished product during storage: if the temperature and moisture are too low, the processing resistance of the tobacco leaves will be reduced , During the pre-pressing and packaging process, a lot of debris is formed, which reduces the use value of the product; if the temperature and moisture are too high, the product is prone to mildew during storage and alcoholization (generally about 2 years), a...

AI Technical Summary

Problems solved by technology

Because the leaves are packaged with a plastic film, and the film will expand during the vacuuming process, increasing the gap between the tobacco billet and the film, and the treatment effect is very limited, so this technology has not been popularized.
