[0002] The powder granulation machine is applied in the powder and noodle production line. The function of the powder granulation machine is to extrude granular powder through a screw barrel and a screw. For example, a powder granulation machine with the Chinese patent publication number CN216605160U includes more than one granulation unit and a driving mechanism for driving the granulation unit; the granulation unit includes a screw barrel, a screw arranged in the screw barrel, an extrusion head arranged at the output end of the screw barrel, and a rotary cutter. A through hole for the screw to extend out is arranged in the middle of the extrusion head, and a plurality of extrusion holes are arranged on the extrusion head. The end of the screw extends out of the extrusion head through the through hole and is connected to the rotary cutter, and the rotary cutter cooperates with the outer side surface of the extrusion head. In this kind of granulation machine, the powder mass is immediately cut into granules by the cutter after extrusion. Since the viscosity of the vermicelli extruded from the just-cooked powder mass is relatively high, the powder is prone to adhesion during cutting, and the granulation effect is not ideal, which will affect the stability of the next extremely crucial wire extrusion process. Summary of the Invention

The vermicelli granulation machine includes an anvil roller, a knife roller, a cutter, and a granulation driving mechanism for driving the anvil roller and the knife roller to rotate. The principle of the utility model: the powder mass is extruded into a long strip shape by the powder mass strip extrusion machine, the vermicelli is conveyed by the vermicelli conveyor and cooled, and the cooled vermicelli is cut into granules by the vermicelli granulation machine; since the powder mass is not granulated immediately after extrusion, but is cooled to reduce the viscosity and then granulated, the adhesion of the powder during granulation is reduced, and the granulation effect is more ideal.

[0006] As an improvement, the extrusion driving mechanism includes a motor, a speed reducer and a transmission shaft. The motor drives the speed reducer through a belt, the output shaft of the speed reducer drives the transmission shaft through a coupling, and the transmission shaft drives the extrusion screw through gear meshing.

[0011] The beneficial effects brought by the present utility model compared with the prior art are as follows:

[0012] Since the cooked powder mass after cooking is not granulated immediately after being extruded into vermicelli by the vermicelli extruder, but is granulated after the viscosity of the vermicelli is reduced by cooling, the adhesion of the powder during granulation is reduced, the granulation effect is more ideal, the powder particles are loose, and it is avoided that the powder mass still adhered together after granulation enters the next extremely critical wire extrusion process, resulting in instability.

In this embodiment, there are two extrusion units in total, which can increase the output. The extrusion unit includes an extrusion barrel 14, an extrusion screw 15 arranged in the extrusion barrel 14, an extrusion driving mechanism 11 for driving the extrusion screw 15 to rotate, a blanking hopper 12 arranged at the input end of the extrusion barrel 14, and an extrusion die head 16 arranged at the output end of the extrusion barrel 14.

A support seat 162 for supporting the end of the extrusion screw 15 is arranged in the middle of the front end of the extrusion die head 16. The rear end of the extrusion die head 16 is connected to an extrusion template 161, and extrusion holes 163 are arranged on the extrusion template 161. A sandwich layer is arranged outside the extrusion barrel 14, and a water inlet and a water outlet are arranged on the sandwich layer. A thermometer is arranged at the water outlet; by injecting cooling water into the extrusion barrel 14, the temperature of the dough is controlled, and further the quality of the extruded vermicelli is controlled so as to meet the processing requirements of subsequent equipment. As Figure 5 shown in the figure, the extrusion driving mechanism 11 includes a motor 111, a speed reducer 112 and a transmission shaft 114. The motor 111 is connected to the input shaft of the speed reducer 112 through a belt. The output shaft of the speed reducer 112 is connected to the transmission shaft 114 through a coupling 113. Two first gears 115 are arranged on the transmission shaft 114, and second gears 116 are respectively arranged on the two extrusion screws 15. The first gear 115 meshes with the second gear 116.

A material loosening shaft 13 is arranged in the blanking hopper 12. The power of the material loosening shaft 13 can be derived from the extrusion driving mechanism 11. When the dough enters the extrusion barrel 14, it is evenly dispersed and enters through the material loosening shaft.
