Pet food raw material grinding device

Abstract

The invention relates to the technical field of pet food production equipment, and particularly discloses a grinding device for pet food raw material, which comprises a box body, a grinding cylinder is rotatably connected to the box body, a rotating shaft is connected to the box body, the rotating shaft is extended into one end of the grinding cylinder and fixed with a first grinding layer, the inner wall of the grinding cylinder is provided with a second grinding layer, the top of the box body is provided with a feeding hopper, the top of the feeding hopper is connected with a cover plate, and a discharging valve is arranged at the bottom of the box body; a planetary gear set is connected between the grinding cylinder and the rotating shaft, which comprises a sun wheel fixed on the rotating shaft, a planet carrier fixed on the box body, a planet wheel connected with the planet carrier, and further comprises an annular gear; A cavity is arranged in the rotating shaft, a first air outlet one-way valve is further arranged on the rotating shaft, a piston and a piston rod are arranged in the cavity, the piston is in threaded connection with the inner wall of the cavity, and the pistonrod is splined to the rack. By adopting the device, after primary grinding is carried out on the raw materials, the first crushed raw materials can be continuously crushed without sieving treatment, the process is continuous, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of pet food production equipment, in particular to a pet food raw material grinding device. Background technique [0002] Pet food refers to food specially provided for pets and small animals, high-grade animal food between human food and traditional feed. Among them, the raw materials of pet food mainly include grains, meat and other nutritionally balanced substances. Among them, the raw materials of grains mainly include rice, corn, wheat, oats, etc., while the raw materials of meat mainly include chicken, fish, beef, meat and bones, etc. [0003] The finished products of pet food are distinguished according to the shape, and generally can be divided into dry pet food, such as: fish food, dog food, cat food, leisure snacks; semi-dry pet food, such as: pet canned food; liquid pet food, such as: Pet meat sauce, pet nutrition porridge, etc. Among them, dry pet food mostly adopts pet puffed dry food processi...

Problems solved by technology

[0004] Usually, after the raw material is pulverized once, there are still larger particles whose fineness does not meet the requirements, and the raw material powder with larger particles will make the internal pore structure of the finished product inconsistent after puffing treatment, resulting in a large size difference between the finished products and The appearance of the finished product is not fine enough, so it is necessary to sieve the conventionally crushed raw material powder, and then continue to carry out secondary crushing for larger particles that do not meet the fineness requirements, which increases the crushing process and increases Investment in equipment reduces production efficiency

[0005] In addition, for factories with small output, in order to shorten the process flow, the pulverizer is usually used to complete the pulverization of raw materials at one time, but for factories with large output, if the raw material is pulverized for the first time, micro pulverization is used, although the process is shortened. process, but this will increase the working pressure of the existing micro-pulverizer, and the material will be heated to a higher temperature during the pulverization process, which may cause the raw material powder to form agglomerates. Therefore, an improved process equipment is needed to overcome the existing Insufficiency of the crushing process, after crushing the raw materials, the raw material powder with fineness meeting the requirements can be obtained
