A feed conditioning device

Abstract

The invention relates to the feed processing machinery field, and aims at providing an efficient feed conditioning device. The adopted technical schemes includes that the feed conditioning device comprises a conditioner with a feed port and a discharge port respectively formed in the upper end and the lower end, a gas distribution plate is arranged in the conditioner, and separates the conditioner into a steam cavity and a conditioning cavity, a hollow main shaft is arranged in the conditioner, a hole is formed in a portion of the main shaft, located in the steam cavity, blades arranged in spiral mode are arranged on another portion of the main shaft, located in the conditioning cavity, one end of the main shaft is connected with a motor, the other end of the main shaft is connected with a steam generator, a preheating roller is arranged above the conditioner, a gear wheel is arranged on the main shaft of the conditioner, and connected with a round rack on the outer peripheral face of the preheating roller, a discharge end of the preheating roller is communicated with the feed port of the conditioner, and a feed end of the preheating roller is connected with a scattering mechanism and a hot air conveying pipe. The feed conditioning device is simple in structure, uniform in air distribution, and efficient in conditioning by adopting a mode of combining preheating with conditioning.

Description

technical field [0001] The invention relates to the field of feed processing machinery, in particular to a feed conditioning device. Background technique [0002] With the rapid development of the breeding industry, the demand for feed is increasing, and the processing of feed is becoming more and more important. Conditioning is an important step in feed processing. It refers to adding steam, liquid additives, etc. to the feed in the conditioning device before pelleting, and stirring and mixing at the same time, so that the feed is matured under humid and hot conditions, so as to facilitate pelleting and granulation. Improve the quality of pellets, improve the palatability of the feed, increase its digestibility, and kill bacteria in the feed, etc. [0003] In the prior art, single-stage or multi-stage paddle-type conditioners are used for the conditioning treatment of feed, and superheated steam is passed into the conditioner. On the one hand, the temperature of the feed i...

Problems solved by technology

[0003] In the prior art, single-stage or multi-stage paddle-type conditioners are used for feed conditioning, and superheated steam is passed into the conditioner. On the one hand, the temperature of the feed is increased. On the other hand, the superheated steam However, it takes time to heat up and condition the feed. Directly feeding superheated steam consumes a lot of energy, which is not conducive to the full use of heat. Secondly, the current way to feed superheated steam into the conditioner is The first method is to directly feed superheated steam through the pipeline, and the second is to use a hollow stirring shaft and open holes on the shaft so that the steam enters the conditioner from the pores, but this method is likely to cause feed to block the pores on the shaft
