Description

Technical Field

[0001] The utility model relates to the field of chitosan production, and more specifically to a shrimp and crab shell decalcification reaction device for chitosan production. Background Art

[0002] The shrimp and crab shell decalcification reaction device for chitosan production plays a vital role in the production process of chitosan. The device is mainly used in chitosan production to decalcify shrimp and crab shells to remove the calcium salt components. The decalcified shrimp and crab shells are easier to further process and improve the extraction efficiency and purity of chitosan.

[0003] Existing shrimp and crab shell decalcification reaction devices are often large in size, which directly leads to some difficulties for operators when performing daily observation and maintenance on them. Especially in the absence of convenient up and down passages, operators often need to rely on unstable auxiliary equipment, such as makeshift ladders, which not only increases the risk of operation but also greatly reduces work efficiency. Even if some reaction devices are equipped with ladders, the ladders are often fixed. Due to the large size of the shrimp and crab shell decalcification reaction device, there are many locations that need to be observed or maintained. The fixed ladder limits the operator's range of movement to a certain extent and cannot meet the operator's needs for observation and maintenance at multiple locations. Utility Model Content
