Cooling device for feed pelletizing

Abstract

The invention discloses a cooling device for feed pelletizing. The cooling device comprises a shunting guide plate, a fine hole diameter sifting net and a rough hole diameter sifting net, wherein a connecting rotating shaft is arranged at a central position of the shunting guide plate; shunting rods which are in array distribution are arranged on the periphery of the connecting rotating shaft; the shunting guide plate is fixed to the inner wall of a housing; the left end and the right end of the rough hole diameter sifting net are separately fixed to the inner wall of the housing through limiting heads; a returning connecting rod is connected to the lower end of the center of the rough hole diameter sifting net through a fixing column; the left side of the returning connecting rod is arranged on a rotating shaft in a sleeving manner through a fixing sleeve; a wind sucking device is arranged on the left side housing of the rough hole diameter sifting net; an inner cavity layer is arranged on the inner wall of the outer side housing of the fine hole diameter sifting net; a water inlet pipe is arranged at the lower end of the left side of the inner cavity layer; and a water outlet pipe is arranged at the upper end of the right side of the inner cavity layer. Through the adoption of the cooling device for feed pelletizing disclosed by the invention, the problems of poor sifting effect and low speed of radiating and cooling caused by the situation that feeds added through a charging opening are easy to accumulate are solved; and the sifting efficiency is high, the cooling effect is good, and the output rate of qualified products is high.

Description

technical field [0001] The invention relates to a cooling device, in particular to a cooling device for pelletizing feed. Background technique [0002] Feed is the general term for the food of animals raised by all people. In a narrower sense, general feed mainly refers to the food of animals raised in agriculture or animal husbandry. The feed includes more than ten varieties of feed materials such as soybean, soybean meal, corn, fish meal, amino acid, miscellaneous meal, additive, whey powder, oil, meat and bone meal, grain, and sweet sorghum. Pellet feed is one of the compound feed products, which is a kind of granular feed made of full-price mixed feed or single feed (grass, cake, etc.) through extrusion. Usually cylindrical, they come in various sizes depending on the species of animal being fed. [0003] In the production process of pellet feed, the powdered feed is first pelletized, which will generate a lot of heat. The temperature of the feed pellets just out of th...

AI Technical Summary

Problems solved by technology

[0003] In the production process of pellet feed, the powdered feed is first pelletized, which will generate a lot of heat. The temperature of the feed pellets just out of the mold is very high, and the feed needs to be cooled, but the feed added through the feeding port is easy to accumulate and cause sieving. The problems of poor separation effect and slow heat dissipation and cooling, and at the same time, there are large particles and defective and broken defective products in the pellet feed after successful pelleting
