Description

Technical Field

[0001] The invention relates to a casing shrinking process. Background Art

[0002] Edible casings are a widely used raw material in the meat processing industry. In the production of casings, the casings need to be shrunk, then cut into sections according to filling requirements, and finally the cut shrunk casings are packaged for transportation or subsequent filling.

[0003] Some casings need to be salted before shrinking so that fine salt adheres to the outer surface of the casing. In order to improve production efficiency, the casings are salted online during the shrinking process. Specifically, in the process of conveying the casings to the shrinking mechanism through the rotating rollers, fine salt is sprinkled on the outer surface of the casing so that the fine salt adheres to the outer surface of the casing.

[0004] However, the conveying speed of the rotating roller to the casing shrinking mechanism is not constant. The rotating speed of the rotating roller will be faster or slower with the action of the casing shrinking mechanism, so that the conveying speed of the casing is coordinated with the action of the casing shrinking mechanism. The amount of salt sprayed is fixed, which will result in insufficient salt sprayed on the outer surface of the casing when the rotating roller rotates fast, and too much salt sprayed on the outer surface of the casing when the rotating roller rotates slowly, which will affect the quality of the final casing product. Summary of the invention

[0005] In order to solve the defects of the prior art, the present invention provides a casing shrinking process, in which casings are conveyed to a shrinking mechanism by a rotating roller, and a salting device is used to apply salt to the casings during the conveying process, the shrinking mechanism shrinks the casings after salting, and then the shrunken casings are cut into sections according to the filling requirements, and finally the cut shrunken casings are packaged for transportation or subsequent filling use; a salting cylinder with salt outlets evenly distributed on the inner circumferential wall of the salting device is provided, and a pair of inner cylinders for closing the salt outlets are provided in the salting cylinder; the casings are allowed to pass through the salting cylinder, and the positions of the pair of inner cylinders are controlled according to the rotation speed change of the rotating roller; When the speed of the rotating roller slows down, the pair of inner cylinders blocks more salt outlets, thereby reducing the output of fine salt and avoiding excessive salting on the outer surface of the casing; When the speed of the rotating roller becomes faster, more salt outlets are not blocked by the pair of inner cylinders, thereby increasing the output of fine salt and not enough salt is sprinkled on the outer surface of the casing.

[0006] Preferably, the salt-spreading device includes: a flat salt-spreading cylinder provided between a rotating roller and a sleeve shrinking mechanism and sleeved on the periphery of the casing, salt outlets evenly distributed on the inner circumferential wall of the salt-spreading cylinder, a salt supply pipe externally connected to the outer circumferential wall of the salt-spreading cylinder, an annular cavity provided inside the salt-spreading cylinder and connecting each salt outlet with the salt supply pipe, a pair of inner cylinders sleeved on the periphery of the casing, coaxial with the salt-spreading cylinder, respectively provided at the axial ends of the salt-spreading cylinder, and the outer circumferential walls of the salt-spreading cylinder being in contact with and slidingly matched with the inner circumferential walls of the salt-spreading cylinder.

[0007] Preferably, the salt spreading device further comprises: a pair of push-pull rods which are separately arranged at the outer ends of a pair of inner cylinders and fixedly connected to the corresponding outer ends of the inner cylinders.

[0008] Preferably, the salt spreading device further comprises: a bidirectional telescopic cylinder which is arranged in parallel to the outside of the salt spreading barrel, is located between a pair of push-pull rods, and has telescopic ends on both sides fixedly connected to the pair of push-pull rods respectively.

[0009] Preferably, the pair of inner cylinders are symmetrically arranged.

[0010] Preferably, the pair of push-pull rods are symmetrically arranged.

[0011] Preferably, the telescopic ends on both sides of the bidirectional telescopic cylinder are symmetrically arranged.

[0012] Preferably, the salting treatment of the casings during transportation by using a salting device comprises the following steps: The casing passes through the salt spreading cylinder, and fine salt is supplied to the annular cavity of the salt spreading cylinder through the salt supply pipe, and the fine salt is sprayed out from the salt outlets evenly distributed on the inner wall of the salt spreading cylinder, so that the outer surface of the casing passing through the salt spreading cylinder is adhered to the fine salt; And the spacing between a pair of inner cylinders is controlled according to the change in the rotation speed of the rotating roller; When the speed of the rotating roller slows down, the two-way telescopic cylinder drives a pair of inner cylinders to approach each other through a pair of push-pull rods, so that the pair of inner cylinders block more salt outlets, thereby reducing the output of fine salt and avoiding excessive salting on the outer surface of the casing; When the speed of the rotating roller becomes faster, the two-way telescopic cylinder drives the pair of inner cylinders away from each other through a pair of push-pull rods, so that more salt outlets are not blocked by the pair of inner cylinders, thereby increasing the output of fine salt and preventing insufficient salt from being sprinkled on the outer surface of the casing.

[0013] The advantages and beneficial effects of the present invention are: providing a casing shrinking process, which can salt the casing before shrinking so that fine salt adheres to the outer surface of the casing; and can control the salt output according to the rotation speed change of the rotating roller to avoid excessive or insufficient salting on the outer surface of the casing, thereby ultimately improving the quality of the casing product.
