Embodiment 1

[0021] 1. Select the feed liquid according to the quality characteristics of the original tobacco and the formula requirements, and select the suitable feed liquid (such as biological preparations, the specific composition is: neutral protease 2wt‰; cellulase 5wt‰; glucoamylase 4wt‰; melanoid 8.9 wt%; tobacco leaf pre-fermentation extract 20wt%; purified water 70wt%), determine the application ratio: feed liquid: tobacco leaves = 40kg: 10000kg.

[0022] 2. According to the concentration of the feed liquid and the volume of the high-pressure water tank, the concentration of the feed liquid added to the tobacco leaves is calculated as 0.4%, and the feed liquid in the liquid storage tank is prepared according to the concentration.

[0023] 3. Use the existing plunger high-pressure pump and high-pressure nozzle system of the re-roasting machine for feeding, and feed in the re-moisture section of the re-roasting machine. Use 4MPa high-pressure water to carry the material liquid thro...

Abstract

The invention relates to a feeding method in processes of tobacco leaf threshing and re-drying. Feed liquid is selected according to quality characteristics of tobacco leaves and added into a moisture regain section of a re-drying machine according to the 0.4% proportion of tobacco leaf weight, high-pressure water is used for carrying the feed liquid to be sprayed on the tobacco leaves of the moisture regain section after sprayer nozzle atomizing, and the temperature at the moisture regain section is controlled to be 55-65 DEG C. The feeding method is even in feeding, high in feed liquid utilization rate and good in feeding effect and keeps a biological agent active, and therefore the purposes that tobacco leaves are safely stored, the quality of the tobacco leaves is improved, and use value of the tobacco leaves is improved are achieved. The feeding is performed on the moisture regain section of the re-drying machine, so that feeding evenness and tobacco lamina safety are guaranteed.

Description

technical field [0001] The invention relates to a method for adding a biological agent in the process of threshing and redrying tobacco leaves in the tobacco industry, which improves the quality defects of tobacco leaves and improves the use value of tobacco leaf raw materials. Background technique [0002] Tobacco leaf rebaking feeding is the process of threshing and rebaking production, the feed liquid is accurately and uniformly applied to the surface of the material, and is fully absorbed by the material, so as to play the role of the feed liquid in improving the quality defects of tobacco leaves and improve the use value of tobacco leaf raw materials . Its purpose is to cover up the inherent quality defects of tobacco leaves in a targeted manner, make the additive material react with the components of tobacco leaves itself during the alcoholization process, improve the quality of tobacco leaves, and thus increase the usability of tobacco leaves. In recent years, the te...
