Experimental determining method of retention in tobacco material roller in processing flow

Abstract

The invention discloses an experimental determining method of the retention in a tobacco material roller in the processing flow, comprising the following steps of: continuously determining the real-time mass flow of materials flowing through the front part and the rear part of the roller by using electronic belt scales which are respectively arranged at the front end and the rear end of roller equipment; acquiring and recording the mass flow data determined by the electronic belt scales by a data acquisition system; continuously acquiring the mass flow information of the materials at the front end and the rear end of the roller at the material head or tail stage; meanwhile, determining the delay time that the materials are transmitted to a roller inlet from the preposed electronic belt scale and transmitted to the post-positioned electronic belt scale from a roller outlet; acquiring the mass flow information of the materials at the roller outlet according to the mass flow information of the materials at the front end and the rear end of the roller and corresponding delay time; and calculating the retention of the materials in the roller at certain moment by the data acquisition system according to the flow of the materials at the inlet and the outlet of the roller at different moments.

Description

technical field [0001] The invention relates to the field of tobacco processing, in particular to an experimental method for measuring the retention volume in a drum during the drum processing of tobacco materials. Background technique [0002] The drum device is a processing equipment commonly used in unit operations such as drying, cooling, combustion, mixing, and humidification. Due to the advantages of large processing capacity, flexible handling of various materials and relatively low operating costs, in the process of tobacco shredded processing, drum equipment is widely used in processing procedures such as loosening and rehydrating, moistening leaves, drying shreds, and adding spices. [0003] Drum material retention refers to the amount of material held inside the drum when the material flows through the drum processing equipment. Drum material retention is an important parameter that reflects the processing load of drum equipment in the production process. In the...

Problems solved by technology

Since this method requires downtime operation, and all the materials in the drum need to be manually collected and weighed, the operation is cumbersome

At the same time, for the production stage where the material flow rate changes continuously, such as the material head and material tail stage, since the material retention of the drum changes continuously with the change of the inlet material flow, the direct measurement method cannot determine the change information of the material retention of the drum in the above continuous process
