Description

Technical Field

[0001] The utility model belongs to the technical field of fermentation equipment, and in particular relates to a mixing and fermenting device for processing feed. Background Art

[0002] Feed is a general term for food for raised animals. In a narrower sense, feed mainly refers to food for animals raised in agriculture or animal husbandry. Feed includes more than ten varieties of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, oils, meat and bone meal, grains, and feed additives.

[0003] At present, more and more livestock are being raised. With the progress of society, the artificial breeding industry has developed greatly, and the demand for feed is increasing. The process of feed production includes raw material cleaning, crushing or grinding, mixing, granulation, drying and packaging. In the process of feed production, fermentation equipment is needed to ferment the raw materials into feed that is easier to digest and has higher nutritional value, so as to improve the quality of feed, reduce costs and improve safety. The quality of fermentation is related to temperature and humidity, pH value and ventilation.

[0004] The existing fermentation device often adopts static fermentation during use, and it is difficult for the feed to fully combine with the fermentation microorganisms, so that the fermentation time is long. Moreover, during the fermentation process, the microorganisms will first ferment the surface of the material and then penetrate downward. Therefore, static fermentation will cause the fermentation speed of the upper and lower parts of the material to be inconsistent, prolonging the fermentation time of the feed and causing the feed to ferment unevenly; in addition, the fermentation process of some feeds requires contact with air. When the feed is accumulated in the fermentation container, the material at the bottom of the container cannot be exposed to fresh air, which easily leads to slower fermentation of the material at the bottom, affecting the fermentation effect of the material; in addition, after the feed is fermented, there will be residual feed attached to the inner wall of the fermentation container. The existing fermentation device is not convenient for scraping the residual material adhered to the inner wall of the fermentation container, which is easy to affect the subsequent fermentation use and increase the labor intensity of the staff. Therefore, it is urgent to design a mixed fermentation device for processing feed to solve the above problems. Utility Model Content

[0032] The present embodiment also includes an electric control console, which includes a PLC controller and a touch screen connected to the PLC controller. The PLC controller is connected to a power supply circuit. The control ends of the auger motor 1 and the rotary motor 19 in the present embodiment are connected to the control end of the PLC controller.

[0035] Working principle:

[0036] Feed and additives are added into the fermentation tank body 16. After the feeding and dosing operations are completed, the feed port 18 is closed, and the PLC controller starts the rotating motor 19 to drive the operating shaft 14 to rotate, and then drives the multiple groups of stirring connection components 13 installed thereon to rotate synchronously to achieve the purpose of stirring the materials. Among them, the rotating linkage mechanism that rotates synchronously with the operating shaft 14 can drive the two groups of stirring mechanisms installed thereon to revolve and rotate at the same time, thereby performing a large-scale and efficient stirring operation on the materials, so that the microorganisms in the additives can fully contact with the materials, shortening the fermentation time of the feed, and avoiding uneven fermentation and inconsistent speed of the feed caused by static fermentation; during the stirring operation, the rotating linkage mechanism that rotates synchronously with the operating shaft 14 can drive the connecting rod mechanism installed thereon to revolve synchronously, and then drive the scraper 10 to revolve, scrape the inner wall of the fermentation tank body 16, and avoid the material adhering to the inner wall of the fermentation tank body 16, which is inconvenient for subsequent cleaning operations;

[0037] After fermentation is completed, the auger motor 1 is started to drive the discharging auger 3 to rotate for discharging operation. After the fermentation tank body 16 is emptied, the cleaning liquid is sprayed into the inner cavity of the fermentation tank body 16 through the cleaning water inlet pipe 17, and the rotating motor 19 is started to make the scraper 10 scrape off the residual material adhering to the inner wall of the fermentation tank body 16, thereby achieving the purpose of cleaning the inner wall of the fermentation tank body 16 and facilitating subsequent fermentation operations.
