Description

Technical Field

[0001] The utility model relates to the technical field of puffing equipment, in particular to a discharging mechanism of an puffing machine. Background Art

[0002] Extrusion puffing technology has long been widely used in the field of bait processing. In existing puffing equipment, in order to obtain extruded puffed products of various sizes and densities with high gelatinization, the material is first tempered with water and steam in the conditioner. The material is fully contacted and penetrated with water and steam in the conditioner. After a certain period of time, the material is pre-gelatinized to a certain extent. The pre-gelatinized material then enters the screw extruder for extrusion. When the extruder is working, the pre-ripened material moves toward the discharge die through the rotatable screw. During the journey from the feed port to the discharge die, the material is subjected to strong mechanical energy when passing through the rotatable screw in the extruder. The temperature and pressure of the material gradually increase. When the material reaches the discharge die, the gelatinization degree of the material reaches the highest state. Then the material is extruded from the discharge die, and then cut to obtain an extruded granular product with a high gelatinization degree.

[0003] When the existing bait extruder is working, the extrusion holes on the extrusion template are often easily blocked, the bait produced is uneven, and the extrusion template is prone to mold explosion, resulting in a short service life of the extrusion mold, a short maintenance cycle, and high maintenance costs. For this reason, we have redesigned the extruder discharge mechanism. Utility Model Content

A hand plate 9 is provided above the screw rod 8, so that the screw rod 8 can be rotated by rotating the hand plate 9.

[0031] A blocking block 6 is provided on the screw rod 8. In the present embodiment, the blocking block 6 is in the shape of a rectangular parallelepiped, and the shape of the blocking block 6 is adapted to the shape of the guide slide cavity 5, so that the lifting and lowering of the blocking block 6 can be controlled by rotating the screw rod 8, thereby preventing the tube 3 from being opened and closed.
