Rapid crayfish pretreatment device

Abstract

The invention relates to the technical field of lobster breeding, and discloses a rapid crayfish pretreatment device. The device comprises a framework, a first water pipe and a second water pipe; a first crayfish frame is arranged on the front side of the top of the framework; a second crayfish frame is arranged on the rear side of the top of the framework; the first crayfish frame is composed ofa plurality of crayfish chambers, filter plates, partition plates and filter screens; the filter screens are fixedly installed at the bottom ends of the crayfish chambers; and the filter plates are fixedly installed at the front ends of the crayfish chambers. Crayfish is placed in the crayfish chambers, sawdust in a sawdust layer simulates sludge, the crayfish is fed rice grains as food, temporarysubstances in crayfish lines are changed, discharge of the crayfish flows out through the filter screens and the filter plates, the crayfish needing to be delivered is placed and fed one day in advance, and a certain proportion of saline water is added into clear water on the framework, so that dirt in the crayfish lines is replaced by the rice grains, the crayfish lines are prevented from beingdrawn out to influence the taste of the crayfish, and meanwhile, gills and viscera substances of the crayfish are completely discharged.

Description

technical field [0001] The invention relates to the technical field of lobster culture, in particular to a rapid pretreatment device for crayfish. Background technique [0002] Crayfish are freshwater economical shrimps, which are popular because of their delicious meat. Because of its omnivorous nature, fast growth and strong adaptability, it has formed an absolute competitive advantage in the local ecological environment. Its feeding range includes aquatic plants, algae, aquatic insects, animal carcasses, etc., and can kill each other when food is scarce. Crayfish has become an important economic aquaculture species in China in recent years. Escape should be strictly prevented in the process of commercial farming, especially escape into inaccessible original ecological water bodies. It causes destructive harm to the ecological competitive advantage of local species [0003] At present, there is an existing patent (announcement number: CN105941585A) and a rapid pretreat...

Problems solved by technology

[0003] At present, there is an existing patent (notification number: CN105941585A) and a fast pretreatment device for crayfish. This patent improves the method of removing gastric pouch and gut, and solves the problem that crayfish restaurants need to manually process a large number of crayfish every day, and the workload is very high. large, and the hands of operators are easily injured by crayfish. However, as the scale of crayfish farming in my country is getting larger and larger, how to increase the sales volume of lobster has become a problem that lobster farmers need to consider. Because the breeding environment of crayfish is relatively dirty , so that there are a lot of sand and stones inside and outside the crayfish, especially the shrimp thread, but the shrimp thread is buried in the meat of the crayfish. If the shrimp thread is pulled out directly, the meat inside will become soft and the crayfish will be lost. The elasticity of the meat makes the taste of the crayfish shop worse, and because of the complicated growth environment of wild crayfish, heavy metals are easy to accumulate in the shrimp line, so the shrimp line needs to be removed, and with the vigorous development of crayfish farming in my country, farming It is difficult for crayfish to come into contact with heavy metal water, but the shrimp line is still dirty
