Stirring shaft, homogenizing and aging machine and sterilizing, homogenizing and aging integrated machine

Abstract

The invention discloses a stirring shaft for stirring ice cream pulp, which comprises a transmission shaft and a lower stirring device arranged at the lower end of the transmission shaft, wherein the lower stirring device comprises a lower stirring body vertically arranged on the transmission shaft and a lower stirring blade arranged on the lower end face of the lower stirring body; an upper stirring device is also arranged on the transmission shaft; and the upper stirring device comprises an upper stirring body vertically arranged on the transmission shaft and an upper stirring blade arranged on the lower end face of the upper stirring body. The invention also discloses a homogenizing and aging machine and a sterilizing, homogenizing and aging integrated machine provided with the stirring shaft. The stirring shaft can prevent the slurry from forming a material layer on the cylinder wall of a cylinder body of the homogenizing and aging machine or the sterilizing, homogenizing and aging integrated machine. The homogenizing and aging machine or the sterilizing, homogenizing and aging integrated machine adopting the stirring shaft has the advantages of strong refrigerating capability, short refrigerating time, long service life, low energy consumption and low cost.

Description

technical field [0001] The invention relates to a stirring shaft for stirring ice cream slurry. [0002] The invention also relates to a homogeneous aging machine and a sterilizing homogeneous aging integrated machine using the stirring shaft. Background technique [0003] The sterilizing and homogenizing aging machine or the homogenizing aging machine is a device for homogenizing and aging the pasteurized ice cream slurry to above 0°C for use in ice cream machines. The agitating shaft currently used in the above-mentioned method comprises a transmission shaft and a stirring body arranged at the lower end of the transmission shaft, and a group of stirring blades is arranged on the agitating body. [0004] There are following problems in adopting the above-mentioned stirring shaft: after aging and refrigeration, the side wall of the cylinder body of the equipment is easy to form a thick material layer (or ice cream layer, ice layer), and this material layer must be melted by...

AI Technical Summary

Problems solved by technology

[0004] There are following problems in adopting the above-mentioned stirring shaft: after aging and refrigeration, the side wall of the cylinder body of the equipment is easy to form a thick material layer (or ice cream layer, ice layer), and this material layer must be melted by reheating or waiting for the temperature to rise It can be used for ice cream machines only after it has become a liquid slurry. This material layer will also affect the cooling effect, prolong the cooling time, waste energy and increase production costs.
