Description

Dextran biomacromolecule finished product automatic collection, crushing and packaging system

technical field

The utility model belongs to the field of biomacromolecule production, in particular to a system for automatically collecting and crushing dextran biomacromolecule finished products.

Background technique

In the process of producing dextran biomacromolecules, a collection and packaging device is required to collect, transport and package the materials. During the production process, we found the following problems in the dry packaging process of dextran biomacromolecules: ①Generally, bags or trucks are used to receive materials at the discharge port of dryers, which will cause dust and secondary pollution; Crushing can only be carried out after feeding, and there are also problems of dust generation and labor intensity; ③biological macromolecules have high viscosity and are easy to absorb moisture. It is easy to form a gelatinous cake and has strong adhesion, so the pulverization speed is slow with a pulverizer, and the yield loss is large (normally, the loss is 2-3%). At the same time, the gelatinous cake has a high hardness after solidification, and it is easy to damage the pulverizer equipment; ④The cleanliness of the original process environment is high and the floor area is large. The whole set of equipment, including drying equipment, crushing and mixing equipment, and packaging equipment, needs to be built in a clean area to ensure product quality (especially the limit of microorganisms); Dust gathers, and on equipment and facilities, when encountering moisture in the air, it quickly absorbs moisture and turns into a gelatinous cake, and it is difficult to clean;
