Multistage conditioner for feed processing

Abstract

The invention discloses a multistage conditioner for feed processing. The multistage conditioner sequentially comprises a primary conditioning tank, a buffer storage tank and a secondary conditioningtank which are connected from top to bottom, control valves are arranged on connectors at the upper end and the lower end of the buffer storage tank, speed regulators are vertically installed in the primary conditioning tank and the secondary conditioning tank, a plurality of layers of speed reducing pieces are arranged on the side walls in a radial mode, and the speed regulators are provided withmultiple layers of paddles which are staggered with the speed reducing pieces and are opposite in inclination direction; steam jackets are arranged outside the primary conditioning tank and the secondary conditioning tank; a plurality of spray pipes connected with the steam jackets are uniformly arranged on the inner walls of the primary conditioning tank and the secondary conditioning tank; an outlet is formed in the bottom of the secondary conditioning tank, the steam jacket of the secondary conditioning tank is connected with an air inlet pipe, the top side of the secondary conditioning tank is connected to the steam jacket of the primary conditioning tank through an air guide pipe, and a feeding pipe and an exhaust pipe are arranged on the top side of the primary conditioning tank. The scattered gelatinization is adopted, the efficiency is higher, the scattering time can be adjusted, and the water content can be changed.

Description

technical field [0001] The invention relates to the technical field of feed processing, in particular to a multistage conditioner for feed processing. Background technique [0002] In the process of feed processing, it is generally necessary to gelatinize the raw materials, that is, to gelatinize the starch by steam, and due to the needs of granulation, the water content after gelatinization should not be higher than 15%, and the water content of the raw materials themselves is about 12%, that is, absorbing steam. The water vapor should not exceed 3%, but the water content needs to be sufficient during the gelatinization process, otherwise it is not conducive to the progress of gelatinization, which is very contradictory. The common method is to use lower temperature steam to increase the gelatinization time. And all adopt the mode of injecting steam in tank, the contact area of ​​raw material and steam is little, and the efficiency of gelatinization is low. Contents of th...

[0002] In the process of feed processing, it is generally necessary to gelatinize the raw materials, that is, to gelatinize the starch by steam, and due to the needs of granulation, the water content after gelatinization should not be higher than 15%, and the water content of the raw materials themselves is about 12%, that is, absorbing steam. The water vapor should not exceed 3%, but in the process of gelatinization, the moisture content needs to be sufficient, otherwise it is not conducive to the progress of gelatinization, which is very contradictory. The common method is to use lower temperature steam to increase the gelatinization time

Moreover, they all adopt the method of injecting steam into the tank, the contact area between raw materials and steam is small, and the efficiency of gelatinization is low
