Technical Field

The invention belongs to the technical field of ice cream equipment, and particularly relates to an evaporator.

Background

Definition of soft ice cream: the soft ice cream is a semi-flow solid frozen dessert produced by a soft ice cream machine, and the soft ice cream has a very fine, smooth and fragrant mouthfeel because the soft ice cream is not hardened. Soft ice cream of good quality should melt immediately in the mouth if left unmelted at room temperature for a long time due to the addition of stabilizers (firming agents) to the ice cream mix to meet the consumer demand. The addition of proper stabilizer can make the ice cream be formed for a long time and properly improve the taste of the ice cream. Clearly the more stabiliser the lower the quality of the ice cream. The high-quality ice cream is melted in the mouth and does not melt for a long time.

The soft ice cream machine is an automatic electromechanical equipment specially designed for producing soft ice cream. The structure of the soft ice cream machine comprises: compressor, condenser, evaporimeter (three are called refrigerating system together), agitator motor, material jar, circuit board and whole frame and shell.

The slurry enters an evaporator, and is extruded to form a soft ice cream finished product after being cooled. The evaporator needs two functions, one is to cool the inside and cool and shape the slurry; one is heating to sterilize the internal slurry and the evaporator itself at high temperatures.

The realization of the heating function of the existing evaporator is that the copper pipe is wound on the outer wall of the inner pipe, and then heated air is introduced into the copper pipe through the compressor to heat the ice cream slurry inside the inner pipe of the evaporator and the inner pipe per se, so that the evaporator is sterilized and disinfected. Such an approach has a problem of low efficiency. The copper pipe is the pipe, and it is on the outer wall of inner tube with winding mode, and the contact mode with the inner tube outer wall is line contact, leads to area of contact very little, and the efficiency of heat transfer just becomes very low, leads to the heating effect not good.
