Stirring device of ice cream machine

Abstract

The invention relates to a stirring device of an ice cream machine. The stirring device comprises a stirring shaft and a stirring blade fixed on the outer surface of the stirring shaft, wherein the stirring blade comprises two groups of flaky blades arranged along the axial direction of the stirring shaft and a stripe blade arranged at the tail end of the stirring shaft. The stirring device further comprises a scraper assembly arranged between the two groups of flaky blades, wherein the scraper assembly comprises a first mounting seat and a scraper arranged on the first mounting seat, and the scraper is in pinned connection with the first mounting seat; in the limited range of the first mounting seat, the scraper slides in a way of contacting the first mounting seat and rotates by taking the back of the scraper as a shaft. By using the stirring device of the ice cream machine, delivery and scraping of slurry can be completed independently, the position of the scraper can be adjusted according to the clearance between the stirring device and the wall of a stirring cylinder so that the scraper can be clung to the inner wall of the cylinder and scrape all slurry, and therefore, a series of problems caused by the clearance between the stirring device and the inner wall of the cylinder are overcome, and the stirring device has the effects of being good in scraping effect, strong in thrust and convenient for changing the scraper.

Description

technical field [0001] The invention relates to the technical field of frozen food processing, in particular to an ice cream machine stirring device. Background technique [0002] The stirring device is an important part of making ice cream in the ice cream machine. When the ice cream machine is working, the ice cream slurry is stirred by the rotation of the stirring device and transported from the rear end of the cylinder to the front end. At the same time, the refrigeration device placed on the periphery of the mixing cylinder The ice cream slurry in the mixing cylinder is cooled, so that the refrigerated ice cream slurry is finally sent to the discharge device to make delicious ice cream. In the ice cream machine of the prior art, the stirring device includes a hollow continuous spiral structure and a broken spiral structure. When the stirring device of the hollow continuous spiral structure is used, the ice cream slurry can be fully refluxed and circulated, but the stirr...

AI Technical Summary

Problems solved by technology

In the ice cream machine of the prior art, the stirring device includes a hollow continuous spiral structure and a broken spiral structure. When the stirring device of the hollow continuous spiral structure is used, the ice cream slurry can be fully refluxed and circulated, but the stirring is insufficient and the thrust is small. It is not conducive to extrusion molding, which affects the working efficiency of the ice cream machine. The working thrust of the stirring device with a broken spiral structure is large enough to meet the efficiency requirements of the ice cream machine. However, due to the gap between the outer periphery of the stirring device and the inner wall of the mixing cylinder There is usually a relatively tight clearance fit between them. Therefore, during the process of rotating the stirring device to stir and transport the ice cream slurry, a layer of ice cream slurry will inevitably remain on the wall of the mixing cylinder, and this part of the remaining slurry will be frozen hard. Afterwards, it is easy to produce the phenomenon of freezing the cylinder, which will gradually affect the cooling efficiency of the ice cream machine and the taste of the ice cream

[0003] In the working of the ice cream machine, due to the center of gravity of the stirring device itself, the stirring shaft will gradually sag and cause eccentricity. The eccentricity of the stirring shaft will gradually increase the gap between the stirring device and the upper end of the mixing cylinder, and the lower end gap shrink gradually

When the gap between the stirring device and the upper end of the mixing cylinder body exceeds a certain level, more slurry cooled on the inner wall of the cylinder cannot be scraped off in time, which is prone to freezing the cylinder, and is also likely to cause damage to the stirring shaft and possibly Seriously affect the overall cooling efficiency of the cylinder; and when the gap between the stirring device and the lower end of the stirring cylinder is reduced, friction between the stirring device and the wall of the stirring cylinder will occur, and the stirring device will wear out day by day, reducing the service life of the stirring device. Moreover, the friction between the stirring device and the cylinder wall increases the resistance of the stirring device to rotate, which may cause the motor to stop rotating in advance, thereby affecting the normal use of the ice cream machine
