Design and Application of Case Storage System for Strips of Single Grade

In order to meet the technology requirements for pretreatment of single grade strips during primary processing and overcome the shortcomings of traditional silo system, such as large site area, a great number of silos of variform silo types, a case storage system for single grade strips was configured via designing of case filling means, storage means, case tipping means and case structure, and incorporating real-time moisture content conversion and static balance metering. The results of application showed that:the storing capacity of the system was up to 1900 cases (120-150 kg/case), which satisfied the need of fine tobacco processing and accurate blending of various strips, and the blending precision raised by 0.29 percentage points. Coal consumption reduced by 546 tons per year, the rate of tobacco breakage decreased by 0.17 percentage points; it ensured the accuracy of tobacco blend and effectively raised the storage density per unit space of the system, and made strip storing and blending a flexible process.
