A method for judging the use end point of film-forming liquid

Abstract

The invention relates to a method for judging a use end point of film forming liquid, and belongs to the technical field of preparation of tobacco brittle capsules. In the process of preparing the tobacco brittle capsules by recycling the film forming liquid, a viscosity of the film forming liquid is measured at time intervals; a change curve of the viscosity along with time is drawn, and when the viscosity reaches the minimum value and then is rebounded, time corresponding to the minimum value is judged as the use end point of the film forming liquid. When the film forming liquid is judged to reach the use end point according to the method, the film forming liquid is replaced. The method disclosed by the invention is rapid and accurate to detect, is good in reproducibility, simple to operate, and convenient to implement, and particularly can achieve online detection, the use end point of the film forming liquid can be more timely judged, and the conditions that mechanical strength of the product does not reach the standard and a defective rate is risen are prevented.

Description

technical field [0001] The invention relates to a method for judging the use end point of a film-forming liquid, and belongs to the technical field of preparation of brittle capsules for cigarettes. Background technique [0002] The concentration of alginate solution in the film-forming liquid during the preparation of crisp capsules for cigarettes by the single-hole method is related to the mechanical strength of the final capsules, and the capsules with too low mechanical strength do not meet the acceptance criteria of the final product. The average mechanical strength of the produced capsules showed a downward trend after the film-forming liquid was thoroughly recycled for many times. How to quickly and accurately judge the use end of the film-forming liquid, prevent the mechanical strength of the product from failing to meet the standard and the rate of defective products, and ensure that the film-forming liquid is replaced in time before the quality of the film-forming ...

AI Technical Summary

Problems solved by technology

[0005] The present invention aims to solve the problem of wasteful use of the current film-forming liquid, and provides a method for judging the recycling end point of the film-forming liquid in the dripping process of brittle capsules for cigarettes by using the viscosity, so as to replace the film-forming liquid in time and ensure the quality of the film-forming liquid. Prevent the mechanical strength of the product from failing to meet the standard and the rate of defective products from increasing
