Background

In the existing cold drink processing equipment, especially an ice cream machine, a stirring shaft is usually adopted to stir ice cream in a stirring cylinder body, so that slurry of the ice cream in the stirring cylinder body is conveyed from the rear end to the front end in the stirring and mixing process, and the mouth feel of the ice cream sprayed out of a nozzle of the ice cream machine is better.

However, the existing stirring shaft mostly adopts a solid shaft, so that the flow of the ice cream slurry in the cylinder body is in a one-way circulation flow, and part of the ice cream slurry is in a frozen state for a long time, thereby destroying the taste and texture of the ice cream slurry. In addition, in order to prevent the cylinder body from freezing, when the blades of the solid stirring shaft rotate, the gap between the blades and the inner wall of the cylinder body is extremely small, so that slurry cooled on the inner wall cannot be scraped in time, the cooling efficiency of the cylinder body is seriously influenced, and adverse effects are generated. And once the phenomenon of freezing the cylinder for a long time occurs, the stirring shaft is likely to be scrapped due to deformation and damage.

Therefore, the utility model with the publication number CN202536032U discloses a stirring shaft, and the stirring efficiency of the stirring shaft is improved by replacing the solid shaft with a hollow shaft composed of a plurality of parallel supporting pillars and providing a plurality of spiral blades on the outer surface of the hollow shaft, so that the ice cream can flow back during the stirring process to realize the circulation flow.

In addition, the ice cream is conveyed from the rear end to the front end, so that the ice cream at the rear end of the stirring cylinder body is easily adhered to the inner wall of the stirring cylinder body for a long time, and the phenomenon of freezing the cylinder is easily caused.
