Embodiment 1

[0025] The mixed material is extruded through the extruding and extruding processing equipment equipped with an enlarged ripening zone.

Embodiment 1

[0026] Embodiment 1 comparative test:

[0027] A) Utilize a single-screw extruder of prior art to carry out production test, obtain relevant parameters. The power of the main motor of the prior art puffing machine is 160 kilowatts, the diameter of the screw is 165 mm, and the length-to-diameter ratio of the screw is 13:1, and the screw configuration area is divided into a feeding area, a kneading area, and a final aging area;

[0028] The formula of the material is shown in Table 1, and the crushing fineness of the material is 95% through the 80 mesh sieve, 99.5% through the 60 mesh sieve, and 100% through the 50 mesh sieve. The material is first pre-cured in a common conditioner. After passing through the conditioner, the gelatinization degree of the material is 45%, the temperature of the material is 95°C, and the moisture content of the material is 19%.

Abstract

The invention discloses equipment and a method for producing high curing extruded products in the field of grain feed machinery, which are used for reducing the input of extruded mechanical energy and improving the input of relatively cheaper heat energy. A conical amplifying segment, a large diameter segment and a conical shrinking segment are arranged at the front part of an extruded cavity of the equipment for producing the high curing extruded products, corresponding screws are respectively a conical amplifying screw, a large diameter screw and a conical shrinking screw, and a steam interface is respectively at the rear part of a feeding cavity and on the periphery wall of an amplifying curing region. The method for producing the high curing extruded products comprises the following steps: firstly tempering materials, respectively adding steam at the rear part of a feeding region and the amplifying curing region, increasing the pressure and temperature of the materials at a tail curing region to realize high gelatinization degree, and finally extruding the materials from the mould holes of a discharging mould and cutting the extruded materials into grains. The production equipment and the production method can lead the materials to have less dependency on mechanical energy in the curing process, and can improve the production capacity under the condition of unchanged inputof the mechanical energy.

Description

technical field [0001] The present invention relates to a kind of equipment for producing puffed products, in particular to a kind of equipment for producing highly mature extruded products; the present invention also relates to a production method of puffed products, especially to a method for producing highly matured extruded products . Background technique [0002] In the prior art, in order to obtain extruded products with a high degree of gelatinization, the material is firstly tempered with water and steam through a conditioner. The material is fully contacted and penetrated with water and steam in the conditioner. After a period of time, the material A certain degree of pregelatinization is obtained. At this time, the gelatinization degree of the material is generally between 35% and 50%. The pregelatinized material is then put into the screw extruder for extrusion.
