New extrusion type food puffing machine

The product of the utility model is an extrusion type food puffing machine to solve the technical problem that the existing extrusion type food puffing machine has poor puffing effect on food.

This extrusion type food puffing machine includes extrusion type food puffing equipment and a decompression module, and the decompression module is arranged at a matching position at the puffing outlet of the extrusion type food puffing equipment, so that the air pressure at the puffing outlet is lower than the environment air pressure.

First of all, the decompression module includes ventilation equipment, the suction port of the ventilation equipment is set at the matching position of the puffing outlet, and the exhaust port of the ventilation equipment is set at a position away from or away from the puffing outlet, so that the ventilation equipment can discharge the puffing outlet. The high-temperature water vapor is extracted; or, the decompression module includes blowing equipment, the air outlet of the blowing equipment is arranged at the matching position of the puffing outlet, and the air inlet of the blowing equipment is set at a position away from or away from the puffing outlet, so that the blowing equipment can Blow away the high-temperature water vapor at the puffing outlet.

Secondly, the decompression module includes an annular branch pipe, and an air port is arranged inside the annular branch pipe, and all puffing outlets of the extruding food puffing equipment are arranged in the ring of the annular branch pipe.

The product also includes a cutting device. The cutting device includes a cutter group. The cutter group includes a knife seat and a cutter installed on the knife seat. The cutter is arranged at a matching position at the puffing outlet to cut the extruded Puffed food.

Compared with the prior art, the beneficial technical effects of the utility model include:

(1) The decompression module can reduce the ambient air pressure at the puffing outlet of the extruded food puffing equipment, that is, form a relatively low-pressure environment lower than the ambient air pressure at the puffing outlet. In a low-pressure environment, the puffing effect of the food is good, which not only helps to improve the puffing effect of the food at the puffing outlet, but also reduces the pressure requirements on the puffing chamber of the extrusion food puffing equipment. Furthermore, the pressure in the expansion cavity of the extrusion food puffing equipment is formed by high-temperature compressed water vapor, and its temperature is generated by the joint action of friction and extrusion, so the pressure on the extrusion food puffing equipment is reduced. The pressure requirements in the puffing cavity can also reduce the temperature of the food in the puffing cavity, and the damage to the nutritional components of the food is low in a low-temperature environment, so the nutritional content of the puffed food produced by the extrusion food puffing machine has a high retention rate.

(2) The use of ventilation equipment or blowing equipment can speed up the airflow velocity at the puffing outlet. In fluid mechanics, the position where the flow velocity is fast has low pressure, which can form a relatively low-pressure environment lower than the ambient air pressure; and increasing the airflow velocity can speed up the puffed food. The evaporation rate and cooling rate of the water inside are beneficial to the preservation of puffed food.

(3) The rotating cutting device has little influence on the extrusion and expansion process of food at the puffing outlet, and can cut food of uniform size.
