Description

Technical Field

[0001] The utility model belongs to the technical field of rice processing equipment, in particular to a device used in an extruder to prevent extrudates from sticking. Background Art

[0002] Recombinant rice, also known as artificial or engineered rice, is made primarily from broken rice, rice flour, or other starch-based raw materials. This product is crushed, tempered, extruded, re-granulated, and dried. Compared to regular rice, recombinant rice offers significant advantages in terms of convenience and quality.

[0003] During the traditional extruded reconstituted rice production process, a cutter is in close contact with the die to cut the extrudate into rice grains. However, this direct cutting method can easily cause the extrudate to stick between the die and cutter, hindering granulation. This problem is particularly prominent when producing rapidly reconstituted reconstituted rice, which has high moisture content and gelatinization degree. Furthermore, research on rapidly reconstituted reconstituted rice has found that soaked and pre-frozen extruded reconstituted rice exhibits superior reconstitution time and edible quality compared to untreated reconstituted rice. However, the addition of soaking and pre-freezing complicates the production process, thus requiring improvement. Utility Model Content

DETAILED DESCRIPTION

[0020] Example 1, see attached Figure 1-4 , a device for preventing extrudate from sticking in an extruder, comprising a cylindrical shell 1, a screw push rod 2 and a spray chamber 3, wherein the screw push rod is matched and installed in the cylindrical shell, and a propulsion motor 21 connected to the screw push rod 2 is installed on the end face of the cylindrical shell 1, and the propulsion motor drives the screw push rod to rotate in the cylindrical shell 1 to push the material forward, and a feeding hopper 11 is provided at the inlet of the cylindrical shell 1, and the raw material is fed into the cylindrical shell 1 from the feeding hopper 11, and a die head 12 is provided at the outlet end, and the die head 12 and the cylindrical shell are connected. The shell 1 is provided with a tapered lead-out section, and the upper part of the outer surface of the spray chamber 3 is provided with a docking hole. The die head 12 is fixedly mounted in the docking hole. A cutter 4 is correspondingly provided at the die head 12. The knife shaft 41 of the cutter 4 crosses the spray chamber 3 from the middle. A cutter motor 42 connected to the knife shaft 41 is installed on the outer side of the spray chamber 3, and the knife shaft 41 and the cutter 4 are driven to rotate at high speed by the cutter motor 42; the upper part of the spray chamber 3 is provided with an upper nozzle 31 facing the extrusion hole 121 of the die head 12, and the lower part is provided with a lower nozzle 32 aligned with the side wall of the spray chamber 3.

[0021] A support base 421 is provided on the outer side of the spray chamber 3, and the motor is fixedly installed on the support base. A reinforcing plate is provided between the support base 421 and the spray chamber 3. The cutter motor 42 is fixedly installed through the support base 421 to ensure safe and stable operation of the cutter motor 42.

[0022] A funnel-shaped discharge port 33 is provided at the lower end of the spray chamber 3 . The purpose of designing the funnel-shaped discharge port 33 is to facilitate the smooth collection of the extrudate.

[0023] The cutter 4 includes two blades that can cover the extrusion end face of the die head 12. The two blades have the same size. The blade shaft 41 is set at the center position between the two blades to ensure stable rotation of the blades. The two blades rotate at high speed on the end face of the die head 12.

[0024] When the device is working, the propulsion motor 21 is started to drive the spiral push rod 2 to rotate in the cylindrical shell 1, pushing the material forward and extruding the material from the extrusion hole 121 of the die head 12. At the same time, the cutter motor 42 drives the cutter 4 to rotate at high speed to cut the extruded material into rice-shaped reconstituted rice. During the granulation process, a nozzle is installed in the spray chamber 3 at the die head 12 to form a spray system. The spray flushing prevents the extrudate from sticking between the die head 12 and the cutter 4, thereby ensuring the granulation effect. At the same time, the reconstituted rice that may adhere to the inner wall of the spray chamber 3 can be removed to prevent its accumulation on the inner wall, thereby ensuring the clean operation of the device.

The differences are as follows: the upper nozzle 31 is a columnar nozzle capable of spraying liquid in a columnar shape. Two upper nozzles 31 are arranged side by side. The total number of nozzles is four, which are respectively arranged at the two corners of the upper part of the spray chamber 3. The purpose of setting the columnar nozzle is to quickly reduce the temperature of the extrudate, thereby reducing its viscosity and effectively preventing adhesion; the lower nozzle 32 is an umbrella-shaped nozzle capable of spraying liquid in an umbrella shape. Two umbrella-shaped nozzles are arranged side by side, respectively arranged at the two corners of the lower part of the spray chamber 3. The umbrella-shaped nozzles are not directly aimed at the extrusion port. Their function is to remove the recombinant rice that may adhere to the inner wall of the spray chamber 3 and prevent it from accumulating on the inner wall, thereby keeping the equipment clean and running efficiently.
