Fish brain sucking method without affecting fish appearance

Abstract

The invention discloses a fish brain sucking method without affecting fish appearance. A frame, a rotary position-changing mechanism, four clamping mechanisms and a suction mechanism; the frame is provided with an inclined end; the rotary position-changing mechanism is arranged on the inclined end; the four clamping mechanisms are arranged on the rotary position-changing mechanism and distributedin a cross pattern; and the suction mechanism is arranged on the frame. The beneficial effects of the method are as follows: fish can be fixed through the clamping mechanisms; the suction mechanism can be punctured into the cavity of the fish brain from the upper jaw inside the fish mouth to suck out the fish brain. As the bones from the upper jaw to brain cavity of the fish are very thin and soft.

Description

technical field [0001] The invention relates to the technical field of fish processing equipment, in particular to a fish brain suction method that does not affect the appearance of fish. Background technique [0002] At present, in fish processing and production, leftovers such as fish heads, viscera, and fish bones account for a high proportion. At present, such leftovers are mainly used as raw materials for animal feed, and their economic benefits are extremely low. If we can make full use of the by-products produced by fish processing and develop their refined processing methods, the economic benefits of the fish processing and production industry can be improved. Fish brains account for about 1% of fish weight and are rich in cephalin and other biologically active substances. , the price of high-purity cephalin on the market is very expensive, and the utilization of fish brain will open up a new way for the whole fish processing and production industry. [0003] In the...

Problems solved by technology

[0003] In the prior art, the main technique for extracting fish brains is to take the brains from the top of the fish’s brain, first drill a hole from the top of the brain, and then move a specific position to carry out the brain suction operation; this operation actually has two disadvantages: one is the production efficiency Low, each time the fish must be drilled first, and then moved to a specific location for brain suction operations; the second is to take the brain from the top of the skull, because the top of the skull is very hard and thick, it needs to be drilled, which is not safe, and it is drilled from the brain , which greatly affects the appearance and quality of the fish, which is not conducive to re-sale
