Problems solved by technology

However, during the puffing process of the extruder, the material will move in the screw sleeve with the rotation of the screw. Due to the change of the thread depth on the screw, the pressure on the material will continue to increase. During this process, the screw sleeve It is very easy to cause blockage and high temperature in the puffing sleeve; moreover, the quality of puffing depends on the press

Embodiment Construction

[0019] In order to clearly illustrate the technical features of the solution, the solution will be described below through specific implementation modes.

[0020] Such as Figure 1-3 As shown, the present embodiment is a mold for a feed extruder, including a disc body 2 arranged at the end of the screw extruding mechanism 1, and a flange 3 is arranged at the end of the screw extruding mechanism 1, and the flange 3 is connected to the The disc body is connected by bolts.

[0021] The disc body 2 is provided with a die hole 4, and the die hole 4 axially corresponds to the cavity of the screw extrusion puffing mechanism 1 and is evenly distributed on the disc body 2; the end of the die hole 4 facing the axis of the screw extrusion puffing mechanism 1 is narrow, and the back One end is wide toward the axis line of the screw extrusion puffing mechanism 1; the die holes 4 are evenly distributed around the axis line of the screw extrusion puffing mechanism 1.

[0022] The disc body 2...

Abstract

The invention discloses a feed expansion machine mold. A disc body with mold holes is provided; orifice pressure induction and adjustment devices are arranged corresponding to the mold holes, so that excessive pressure can be released relatively quickly according to the sizes of pressure adjustment orifices; and the orifices are decreased to guarantee feed expansion quality when the pressure is insufficient. Pressure adjustment of the orifice pressure induction and adjustment devices is mainly accomplished by springs and orifice adjustment blocks pushed by the springs. The mold has the benefits that the mold is simple in structure and reasonable in design; the adjustment of maximum pressure in a helical extrusion expansion mechanism is achieved; when the pressure is excessive, the orifices can be enlarged to avoid blocking and release the pressure; when the pressure is reduced, the orifices can be decreased to guarantee the feed expansion quality; the quantitative adjustment of the maximum pressure can be achieved; and the mold is very significant for improving production safety and the product quality.

Description

technical field [0001] The invention relates to feed production equipment, in particular to a feed extruder mold. Background technique [0002] Feed extruder has been widely used in the field of food and feed processing. Expansion is a technological operation in which the material is humidified, heated and tempered, and extruded out of the die hole or suddenly ejected out of the pressure vessel, and the volume is expanded due to a sudden drop in pressure. Extrusion technology has been widely used in the field of food and feed processing. In the prior art, in order to obtain extruded puffed products of various sizes and densities with high gelatinization degree, the material is firstly passed through a conditioner using water and steam for conditioning, and the material is mixed with water, water and steam in the conditioner. The steam is fully contacted and penetrated, and after a certain period of time, the material is pre-gelatinized to a certain extent, and the pre-ge...
