Stainless steel auger of ice cream machine

Abstract

The invention provides a stainless steel auger of an ice cream machine, which comprises a stainless steel mixing barrel, wherein an auger shaft and an auger blade are installed in the stainless steel barrel; the auger shaft comprises a positioning shaft and an auger fixing shaft; a bottom plate is connected between the positioning shaft and one end of the auger fixing shaft; a material pushing impeller is connected at the other end of the auger fixing shaft; the auger blade is a spiral blade made of stainless steel; a fixing shaft of the material pushing impeller is installed at a side of an edge between the bottom plate and the material pushing impeller; a plastic scrapper which can swing freely is arranged at the outer part of the fixing shaft of the material pushing impeller; and the plastic scrapper is matched with the inner wall of the stainless steel mixing barrel. In operation, the positioning shaft is driven to rotate through a driving force, and drives the bottom plate, and the fixing shaft of the stainless steel auger connected on the bottom plate; the spiral blade made of stainless steel is installed on the fixing shaft of the auger; particularly the plastic scrapper which can swing freely is arranged at the outer part of the fixing shaft of the material pushing impeller, therefore, the plastic scrapper always adheres to the inner wall of the mixing barrel, and materials on the inner wall of the mixing barrel can be scraped cleanly in time.

Description

technical field [0001] The invention relates to an ice cream machine, in particular to a stainless steel auger for an ice cream machine, which belongs to cold drink machinery. Background technique [0002] Ice cream has the characteristics of smooth and delicate, cool and delicious. Especially in summer, people like to eat more. The ice cream machine mainly includes a refrigeration system and an extruding system, and the extruding system includes power, a variable speed transmission mechanism and an extruding device. The extrusion device includes a mixing drum in the evaporator, an auger installed in the mixing drum, an extrusion die matched with the mixing drum, and the like. The auger includes an auger shaft, an auger scraper mounted on the auger shaft, and a pushing impeller. When working, when the various materials for making ice cream enter the mixing drum, they are cooled on the one hand, and on the other hand, the auger stirs, puffs and mixes them, and continuously...

AI Technical Summary

Problems solved by technology

The auger of the existing ice cream machine adopts the agitator shaft and the scraper made of plastic as a whole. All the stirring, pushing and scraping are all based on the scraper. In the actual product, there is at least a certain gap between the auger and the mixing drum. Since the mixing drum works under refrigeration conditions, when the material sticks to the wall of the drum and cannot be scraped off in time, even a thin layer of ice will greatly reduce heat transfer and increase energy consumption

On the other hand, the mixing uniformity of the plastic auger is poor, which affects the quality of ice cream
