On-line feeding method and device, and expanded shredded tobacco production system

Abstract

The invention discloses an online feeding method and device, and an expanded shredded tobacco production system. The method includes: collecting in real time the current cut tobacco flow rate of the electronic belt scale set in front of the primary dampening machine; according to the current cut tobacco flow rate and the predetermined feeding ratio K 0 Determine the theoretical applied flow rate of the material liquid; obtain the working frequency f of the metering pump associated with the theoretical applied flow rate of the material liquid; output the working frequency f to the metering pump so that the metering pump works at the working frequency f, and convert the theoretical The feed liquid with the applied flow rate is transported from the storage barrel to the nozzle, and sprayed on the shredded tobacco in the primary conditioning machine, wherein the feed liquid includes a humectant. The present invention installs the on-line feeding device at the primary dampening drum, which can reduce the loss of aroma components and other components of shredded tobacco during the expansion process under the premise of maintaining the normal expansion effect of shredded tobacco, thereby improving the sensory quality and physical moisture retention of shredded tobacco performance.

Description

technical field [0001] The invention relates to the field of cigarette processing, in particular to an online feeding method and device, and an expanded shredded tobacco production system. Background technique [0002] Currently CO 2 Shredded tobacco expansion technology is one of the important means for the domestic tobacco industry to reduce harm, reduce coke, and reduce cigarette consumption. CO 2 The principle of shredded tobacco expansion technology is to soak shredded tobacco with carbon dioxide liquid at a certain temperature and pressure, so that carbon dioxide can fully penetrate into the shredded tobacco, and then quickly depressurize it, so that the liquid carbon dioxide in the shredded tobacco can be solidified into solid carbon dioxide, and then use high-temperature airflow to quickly heat the shredded tobacco, so that The carbon dioxide sublimates, the volume expands rapidly, and the shrunken tobacco cell wall is opened, so that the volume of the tobacco beco...

AI Technical Summary

Problems solved by technology

This leads to sensory defects such as insufficient aroma of shredded tobacco, obvious miscellaneous gas, and increased stimulation. It also causes the problems of reduced flexibility, lower processing resistance, and lower physical moisture retention performance of shredded tobacco.
