A conditioning method and device

Abstract

The invention discloses a tempering method and device, which is characterized in that after the material processed by the pre-conditioned layer enters the quality-preserving layer, it is further mixed with steam in the quality-preserving layer for conditioning and quality-preserving, and the rotor of the quality-preserving layer runs forward and backward. The material flows back and forth in the quality-preserving fuselage to obtain sufficient heating and tempering time. Under the joint action of the heating and heat preservation system and steam, the temperature rises rapidly. After the temperature rises to the set value, the material is discharged downstream for granulation. The device includes pre-conditioning layer, preservation layer, pre-conditioning drive system, heating and heat preservation system, pre-conditioning rotor, pre-conditioning body, steam addition system, preservation drive system, preservation rotor, preservation body, material temperature sensor ,Temperature Sensor. The invention can reduce the discharge of the head material during the start-up process, simplify the layout of the production process, improve the utilization rate of raw materials and feed safety and sanitation, reduce the energy consumption of the granulator, and reduce the labor intensity of workers.

Description

technical field [0001] The invention relates to a tempering method and device, belonging to the technical field of grain and feed processing equipment. Background technique [0002] Feed needs to be subjected to steam high-temperature conditioning treatment on the powder before pelleting. The equipment for conditioning treatment is called a conditioner, which uses steam to sterilize the powder at high temperature, eliminates the anti-nutritional factors in the raw material, improves the degree of maturity, and achieves Excellent breeding effect. During the tempering process, the small particles of the powder absorb water, soften the core, and make subsequent granulation easier. Temperature, moisture, and time are the three key indicators to measure the tempering effect. In order to achieve a good tempering effect, it is usually achieved by increasing the tempering temperature and prolonging the tempering time. However, when the production is just started, the temperature of...

Problems solved by technology

The waste generated during the start-up process usually weighs tens to hundreds of kilograms. It is necessary to design a separate process for conveying, storing, and processing the waste. Workers need to transport this part of the material to the waste disposal site, which is time-consuming and laborious.
