1results about How to "Achieve preheating" patented technology

This utility model discloses an extrusion puffing machine with a heating structure, including an upper tube body. A reduction motor is fixedly connected to the left side of the upper tube body, and a screw shaft is movably connected to the left side inside the upper tube body. The output end of the reduction motor extends into the interior of the upper tube body and is fixedly connected to the screw shaft. A heating structure for preheating the raw material is provided on the left side of the top of the upper tube body. This extrusion puffing machine with a heating structure has a heating tank. During processing, the raw material is introduced into the heating tank through the feeding port. The electric heaters on both sides of the heating tank are activated, conducting heat to the inside through the heat-conducting layer, thereby heating the raw material inside the heating tank. Simultaneously, the drive motor is activated, driving multiple sets of stirring rods to rotate via a rotating shaft. The rotation of the stirring rods stirs the raw material inside the heating tank, improving heating uniformity and solving the problem of not being able to preheat the raw material.
