Process for shredding tobacco stems by dry ice

Abstract

The invention provides a process for shredding tobacco stems by dry ice. According to the process, the tobacco stems are loaded into a special container, in addition, carbon dioxide is filled into the container, tobacco stem dry ice blocks are manufactured through a dry ice producing device, the tobacco stem dry ice blocks are shredded according to requirements, the tobacco stem shreds are obtained after the carbon dioxide is sublimated, and the sublimated carbon dioxide is recovered and utilized.

Description

technical field [0001] The invention relates to a shredded tobacco processing technology, in particular to a dry ice shredding technology of tobacco stems. Background technique [0002] At present, the known tobacco stems can be used to make cigarettes, which account for 25% of the whole tobacco leaf. When the tobacco factory shreds, only the thicker parts can be used. The thinner and shorter tobacco stems cannot be cut into shreds and are wasted. Cutting thin tobacco stems into shreds is a major problem in the cigarette industry. Contents of the invention [0003] In order to overcome the problem of cutting thin and short tobacco stems, the present invention provides a process for cutting tobacco stems. The process uses carbon dioxide and tobacco stems to condense into dry ice and then shreds. The carbon dioxide is sublimated to obtain shredded tobacco stems. Retained, sublimated CO2 is recycled. [0004] The technical solution adopted by the present invention to solve ...
