Puffing combination pump apparatus used for ice cream makers, and ice cream maker

Abstract

The invention discloses a puffing combination pump apparatus used for ice cream makers. The apparatus comprises fixed boxes, combination pumps arranged in the fixed boxes, tee pipe joints, and feeding assemblies and discharging assemblies which are respectively connected with the combination pump; and every combination pump comprises a liquid pump and an air pump which are integrated into one, the feeding openings of liquid pumps are connected with the feeding assemblies, the discharging openings of liquid pumps are in threaded connection with the tee pipe joints, and the air outlets of the air pumps are connected with the discharging assemblies through the tee pipe joints. The puffing combination pump apparatus can effectively improves the puffed rate of ice cream to 55-65%, has a very substantial and stable puffing effect, makes ice cream made by using the apparatus have fine, soft and smooth mouthfeel, and has the characteristics of simple structure, low cost, convenient cleaning and detaching, good reliability, greenness and environmental protection. The invention also discloses an ice cream maker.

Description

technical field [0001] The invention relates to the field of frozen food machinery and equipment, in particular to an expanded composite pump device for an ice cream machine. The invention also relates to an ice cream machine. Background technique [0002] The puffing device is a very important device in the ice cream machine. It mixes a large amount of air into the ice cream slurry to expand the volume of the slurry, so as to obtain fluffy ice cream products with high quality, fine and smooth taste and attractive appearance. Ice cream machines are generally equipped with puffing tubes or puffing pumps as the puffing device. The puffing effect of the puffing tube is limited, the air cannot be fully and evenly mixed, and the puffing rate is low and unstable, which does not meet the high-quality puffing rate requirements. At present, most ice cream machines sold on the market use gear pumps or plunger pumps as puffing pumps to improve the puffing pump of ice cream and improve...

AI Technical Summary

Problems solved by technology

In order to meet a certain relationship between pressure and flow, a certain amount of air is added into the cylinder, and at the same time, the slurry in the cylinder cannot flow backwards. Therefore, the intake pipe of the plunger pump is generally thicker, and the size of the pump is relatively large. , the machining accuracy and installation accuracy of the piston in the cylinder are high, which is not conducive to frequent assembly and disassembly

In addition, the plunger pump has an empty stroke problem during operation, and the work efficiency is low

If the seal of the piston is worn, it will lead to the failure of normal suction
