Abstract
Description
Technical Field
[0001] The utility model relates to the field of fresh food processing devices, in particular to a crayfish shelling machine. Background Art
[0002] China is the world's largest producer of shrimp products and a major trading country for shrimp products in the world. Shrimp meat is rich in protein, and the meat is soft and easy to digest, making it a delicious ingredient. However, every time you eat shrimp, you have to peel the shrimp shell, which is very troublesome, and the manual removal of the shrimp thread is even more cumbersome, so a shrimp peeling machine was born. Existing shrimp peeling machines generally use a pretreatment device to first separate the shrimp shell and shrimp meat from the frozen crayfish by centrifugation, and then send them to the shrimp peeling machine for final separation. However, since the shrimp shell of the crayfish is relatively hard and the shrimp body will curl up after death, the existing shrimp peeling machine cannot be directly used for shelling. At the same time, even if the crayfish is pretreated, it is more difficult to peel the shell than conventional shrimp, and the crayfish cannot be peeled at the shelling speed of ordinary shrimp. Therefore, a new type of crayfish peeling machine is urgently needed to solve the above problems. Utility Model Content

[0043] ① In this utility model, reference is made to Figure 1 and 2The caught shrimps are first pre-treated by ice water freezing, stirring, etc., so that the shrimp shells and shrimp meat are initially separated. The device for pre-treatment is a stirring tank. The shrimps are stirred by a stirring paddle in the stirring tank, so that the shrimp shells and shrimp meat are initially separated. In order to improve the pre-treatment effect, ice water can be added to the stirring tank. The ice water can shrink the shrimp meat and further improve the effect of the initial separation. The pre-treated shrimps are transported to the feeding device 30 through the feeding device 20. The feeding device 30 has two functions, one is to transport the crayfish, and the other is to make the crayfish in the feeding device 30 change from a curled state to a straight state. Specifically, the feeding device 30 includes a receiving device The hopper 31 has a material receiving trough 311 therein; a plurality of material discharging cylinders 32 are arranged on the material receiving trough 311 and connected to the material receiving trough 311; a first auger 33 is arranged in the material receiving trough 311 and extends along the length direction of the material receiving trough 311; a second auger 34 is arranged in the material discharging cylinder 32 and extends along the length direction of the material discharging cylinder 32; a first driving assembly 35, an output end of which is connected to the first auger 33; a second driving assembly 36, an output end of which is connected to the second auger 34; after the action of the first auger 33 and the second auger 34, the crayfish are not only roughly corrected to a straight state, but also fall one by one onto the shelling device 40.
[0044] ②Reference Figure 1 and 3 In the shelling device 40, the shelling device 40 includes a fixed frame 41; a plurality of groups of shelling rollers, each group of shelling rollers includes a large roller 42 and a first small roller 43 and a second small roller 44 arranged above the large roller 42 and located on both sides of the large roller 42, and one end of the large roller 42, the first small roller 43 and the second small roller 44 is connected to one end of the fixed frame 41 through a bearing; a fourth driving assembly 45 is arranged at the other end of the fixed frame 41 and connected to the other ends of the large roller 42, the first small roller 43 and the second small roller 44; specifically, the feeding device 30 transports the crayfish between the first small roller 43 and the large roller 42 and between the second small roller 44 and the large roller 42, wherein the fourth driving assembly 45 drives the large roller 42, the first small roller 43 and the second small roller 44 to rotate, so that the crayfish rub between the first small roller 43 and the large roller 42 and between the second small roller 44 and the large roller 42, so that the shrimp shells are peeled off and fall under the shrimp peeling rollers, and after being collected by the collecting trough, they fall into the shrimp shell box under the impact of the water flow, and the shrimp meat falls onto the discharging device 60 under the impact of the water flow.
