Description

Technical Field

[0001] The utility model relates to the field of lobster head removal, in particular to a head removal device used for crayfish processing. Background Art

[0002] Crayfish, also known as Procambarus clarkii, red crayfish and freshwater crayfish. It is a freshwater economic shrimp with a shrimp-like shape but hard shell. It is widely popular because of its delicious meat. It has an absolute competitive advantage in the local ecological environment because of its omnivorous nature, fast growth rate and strong adaptability. Therefore, it is suitable for large-scale artificial breeding, and crayfish series dishes have become popular. However, an important reason why crayfish has been frequently exposed as unsafe in recent years is the unsanitary production. When making crayfish, restaurants usually need to manually clean the crayfish, such as spitting out dirt and removing mud, etc., and these steps take a lot of time and cost. Therefore, a considerable number of stores will only simply clean the crayfish, so that it still carries a lot of pollutants, especially its head is the part where heavy metals accumulate the most, which still poses a threat to the diners' health. Therefore, the long cleaning time and high labor costs have become an important factor affecting its hygienic production.

[0003] After searching, a crayfish head removal and cleaning device with a publication number of CN201811065726.8 is disclosed, which specifically includes a machine body, a working groove connected to the left and right, a clamping mechanism for fixing the crayfish and a driving mechanism for dragging the clamping mechanism to move left and right in the working groove, the lower end of the driving mechanism is fixedly connected to the upper end of the clamping mechanism, a cleaning mechanism and a cutting mechanism for cooperating with the clamping mechanism and both arranged on the moving path of the clamping mechanism are installed at the bottom of the working groove, the cutting mechanism is driven by the driving mechanism, a flushing mechanism is provided in the machine body, the flushing mechanism is connected to the external water supply equipment, and the flushing mechanism is located directly below the clamping mechanism. The advantages are: the present invention can quickly and effectively clean multiple crayfish at the same time so that the restaurant can reduce labor costs, and at the same time, the heads of the crayfish can be cut off, saving time in making dishes.

[0004] However, the above-mentioned device still has certain defects. For example, crayfish are often manually de-headed during processing, which often consumes a lot of labor and has low production efficiency. When removing the lobster head, the existing lobster de-heading tool will leave a large amount of blood and stains in the lobster body. If it is not cleaned quickly, the tool will stink and rot, which is not conducive to de-heading the lobster in the later stage of the processing device.

[0005] Therefore, it is necessary to invent a head removal device for crayfish processing to solve the above problems. Utility Model Content
