Abstract
Description
Technical Field
[0001] This utility model relates to the field of pellet meal production technology, specifically to a dust collection and recovery system for pellet meal workshops. Background Technology
[0002] The sugar production process consists of the following steps: beet washing, shredding, leaching, pressing, pellet production, ash addition, saturation, filtration, evaporation, crystallization, and packaging. The pellet production section mainly involves sending the waste beet shreds from the pressing section to a dryer for drying. After drying, the shreds are granulated into pellets for use as livestock feed.
[0003] Dust is generated during the drying process in the pellet production section of the dryer, and dust is also generated during the discharge process at the pellet mill outlet. In order to ensure the working environment of the operators and meet environmental protection requirements, dust reduction measures are required to reduce the health threats to the operators. At the same time, yeast needs to be added for special pellets to increase their nutritional value. Currently, yeast is added by mixing yeast powder with the pellets during the pelleting process, but the mixing effect is not good and the yeast powder is unevenly distributed. Utility Model Content
