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

Abstract

The invention discloses an expanded composite pump device for an ice cream machine, which comprises a fixed box, a composite pump arranged in the fixed box, a three-way pipe joint, a feed assembly and a discharge assembly respectively connected with the composite pump; The composite pump includes a liquid pump and an air pump fixed as one, the feed port of the liquid pump communicates with the feed assembly, the discharge port of the liquid pump is threadedly connected with the three-way pipe joint, and is connected with the discharge port of the air pump. The air port communicates with the discharge assembly through the three-way pipe joint. The puffing compound pump device of the present invention can effectively increase the puffing rate of ice cream within the range of 60%±5%, and the puffing effect is very significant and stable, so that the prepared ice cream has a delicate and smooth taste, and has the advantages of simple structure and low cost. , Easy to clean and disassemble, good reliability and green environmental protection. The invention also discloses an ice cream machine.

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
