Device and method for automatically removing shrimp lines

Abstract

The invention belongs to the field of mechanical design and relates to a device and method for automatically removing shrimp lines. According to the device and the method, by the use of a color difference between a shrimp section and the surrounding and the adoption of an optical fiber sensor for color recognition, a cutter is precisely located to a penultimate shrimp section from the shrimp tail.A special cutter is adopted, which has an arc-shaped edge fitted to the shape of the shrimp back; a small opening is formed in the shrimp back, and then the shrimp line is hooked out from the side ofthe shrimp with a shrimp line hook. The shrimp line hook is made of a shape memory alloy, and the shrimp line hook is in an open state at normal temperature and is in a closed state at a high temperature; when the shrimp line hook hooks the shrimp line, the temperature of the shrimp line hook is raised, and the shrimp line hook is closed to slightly clamp the shrimp line. The device is simple instructure and convenient to use and can ensure that the shrimp line cannot fall off in the hooking process and guarantee the integrity of a shrimp.

Description

technical field [0001] The invention belongs to the field of mechanical design, and relates to a device and method for automatically removing shrimp lines. Background technique [0002] In recent years, people's quality of life has been gradually improved, and people's requirements for food are getting higher and higher. Not only the taste of food is pursued, but also the beauty of food is valued. At the same time, food hygiene and safety are also paid more and more attention. Shrimp is delicious and has high nutritional value, and is loved by more and more people. The shrimp line is the intestine of the shrimp, which is located on the back of the shrimp and is black or light in color. Shrimp thread belongs to the excrement of shrimp, which contains a lot of bacteria, sediment, heavy metals and other dirty things. If the shrimp line is not removed and cooked directly, it may cause symptoms such as diarrhea for people with weak resistance. At the same time, the shrimp thr...
