Carapace pretreatment device and equipment for recycling crustacean solid wastes

Abstract

The invention belongs to the technical field related to the recycling of crustacean solid wastes, and discloses a carapace pretreatment device and equipment for recycling crustacean solid wastes. Thecarapace pretreatment device includes a feeding hopper, a first pulverizing mechanism, a first solid-liquid separating mechanism, a second pulverizing mechanism, a second solid-liquid separating mechanism, and a first liquid collecting chamber, wherein the first pulverizing mechanism is connected with the feeding hopper and the first solid-liquid separating mechanism; the second pulverizing mechanism is connected the first solid-liquid separating mechanism and the second solid-liquid separating mechanism; the first solid-liquid separating mechanism, the second pulverizing mechanism and the second solid-liquid separating mechanism are all housed in the first liquid collecting chamber; and the first pulverizing mechanism and the second pulverizing mechanism are used for secondary pulverization of the crustacean raw materials to obtain solid materials and liquid substances for chitosan and protein extraction respectively. The device improves the efficiency and the degree of automation, and has high applicability.

Description

technical field [0001] The invention belongs to the technical field related to the recycling and utilization of crustacean solid waste, and more specifically relates to a crustacean pretreatment device and equipment for recycling and utilizing crustacean solid waste. Background technique [0002] With the rapid growth of consumption of shrimp and crab aquatic products in recent years, crustacean solid wastes such as shrimp shells and crab shells have piled up like mountains. According to incomplete statistics, at present, various crustacean solid wastes produced by the consumption of aquatic products in my country exceed 8.5×10 5 Ton. These wastes are usually directly discarded as domestic garbage, and huge natural resources are not only wasted in vain, but also cause serious pollution to the ecological environment. It is reported that currently only a very small part of the carapace has been recycled, such as the preliminary processing of shrimp and crab shells into shrim...
