Embodiment Construction

[0050] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0051]In view of the inaccurate spraying accuracy and uniformity of the feed liquid in the current blade feeding process, which may easily cause inconsistent quality of tobacco leaves within or between batches and affect the quality of tobacco, the present invention provides a feed liquid control method and system for blade feeding In the same batch, by setting the PID feedback control model to adjust the steam injection volume of the feed liquid to control the water content at the outlet, it solves the problem of inaccurate control of the spraying accuracy and uniformity of the feed liquid when feeding the existing blades, and can improve the quality of each batch. The consistency of blade feeding uniformity imp...

Abstract

The invention provides a feed liquid control method and system for blade feeding, and the method comprises the steps: setting the hot air temperature and circulating air volume of a blade feeding machine according to a set value, and setting a target value of the outlet moisture content of a blade feeding process; obtaining an actual measurement value of the outlet moisture content of the blade feeding process, and obtaining a target deviation value of the outlet moisture content according to the target value and the actual measurement value; and establishing a PID feedback control model for adjusting the feed liquid steam injection amount according to the target deviation value so as to carry out feedback control on the outlet moisture content, so that the outlet moisture content of the blade feeding process in the batch is controlled according to the target value. The consistency of the charging uniformity of each batch of blades can be improved, and the quality control capability inthe production process is improved.

Description

technical field [0001] The invention relates to the technical field of tobacco processing, in particular to a method and system for controlling feed liquid of blade feeding. Background technique [0002] Leaf feeding is an important process in the production and processing of tobacco. According to the formula requirements, that is, the material liquid is applied to the tobacco according to the feeding ratio, and the irritation and miscellaneous gas of the tobacco are reduced through the feeding process, and the sensory quality and physical quality of the tobacco are improved. characteristic. At present, the feeding control is that the feeding system applies the feed liquid to the tobacco according to the blade flow rate and the feeding ratio during the production process. Since the precision and uniformity of the feeding liquid directly affect the quality of the tobacco, it has a great influence on the smoking taste of the cigarette. Existing feed liquid control usually di...
