Description

Flesh of fish subtracts decreases and adopts meat device

Technical Field

The invention relates to a fish flesh loss reducing and meat collecting device, and belongs to the technical field of fish flesh processing machinery.

Background

The minced fillet is an intermediate raw material for minced fillet products, which is prepared from fish meat by the procedures of meat collection, rinsing, fine filtration, chopping, mixing, adding an anti-freezing agent and the like. The degree of tissue damage of the fish meat during the meat-cutting process determines the sensory quality of the fish meat in the minced fillet product. The smaller the breakage, the better the original tissue retention of the fish meat, and the stronger the fibrous feeling of the fish meat of the prepared minced fillet product, otherwise, the stronger the adhesive feeling. The traditional fish meat collecting device utilizes mutual friction between a rolling meat collecting cylinder and a transmission conveyor belt to extrude fish meat into the meat collecting cylinder, and fish skin and fish bones are left outside the meat collecting cylinder, so that preliminary separation of the fish meat, fish bones, the fish skin and the like is realized.

The traditional meat-picking device enables the processing of minced fillet to be produced in a large scale, but is limited by the processing principle of the minced fillet, and the device mainly has the following problems in the meat-picking process: (1) the meat particles obtained by squeezing and picking the meat are small, and the fiber is seriously damaged; and because the fish meat has fishbone, the fishbone is removed through a fine filtration step, so that the fish tissue is further damaged and becomes a erosive state. This is contrary to the new trend of consumption of pursuing the feeling of fish fiber; (2) the belt of the traditional meat collecting device is tightly attached to the roller, the abrasion problem exists in the operation process, the damage to the conveyor belt is serious, the service life is usually 3-5 months, the conveyor belt needs to be frequently replaced, and resources are wasted.

Patent publication No. CN205409379U discloses a fish flesh separator, which reduces the introduction of fish bones by reducing the diameter of small meat-separating holes, but only leaves hard and large fish bones in the fish outside, and soft and small fish bones in the fish flesh enter the meat-separating cylinder along with the fish flesh under the mutual pressing movement of a meat-separating roller and a conveyor belt, so that the aim of removing the fish bones in the meat-separating step cannot be achieved. Meanwhile, the smaller the aperture of the collected fish is, the larger the damage degree of the fish fiber is.

Patent publication No. CN107333862A discloses a flesh separator for fish, this flesh separator sets up two pressure running rollers, can make things convenient for the fish piece to get into between flesh separator and the belt, plays the guide effect to the feeding of material through this mode, avoids taking place the putty phenomenon, can also play the effect of pre-compaction to the fish piece simultaneously, still need to adopt the flesh through the mutual extrusion force of adopting meat cylinder and conveyer belt, therefore the wearing and tearing problem of conveyer belt is not substantively solved, and life still is shorter.
