Problems solved by technology

Because the copper tube is in line contact with the cylinder wall, the contact area is very small. At the same time, the contact between the copper tube and the cylinder wall will also cause contact thermal resistance, and the uncontacted part is filled with materials with low thermal conductivity such as air or insulation materials. Therefore, this The heat transfer coefficient of the evaporator is low, and the required heat transfe

Example Embodiment

[0023] In order to better explain the preferred embodiment of the ice mushroom machine of the present invention, firstly, refer to the cross-sectional side view of the first embodiment of the present invention shown in FIG. 1. This picture shows the basic structure of the ice mushroom machine. The evaporator 8 is placed in the beverage box 3 near the bottom of the box. Refer to the front view of the ice scraper 5 shown in FIG. 5: the ice scraper 5 has a threaded hole 14 and a plurality of through holes 13. Refer to the cross-sectional view taken along the line AA shown in Fig. 2: The evaporator 8 is composed of a plurality of metal straight pipes 4, where the straight metal pipe 4 passes through the wall of the beverage box is sealed with a sealing device 10, and the straight metal pipe 4 is in front of the entrance There is a refrigerant distributor 12, and an ice scraper 5 with a plurality of through holes 13 as an ice scraper is sheathed on the evaporator 8. The straight metal ...

Abstract

The invention is concerned with the soft ice machine, includes the beverage box, the feeding opening, the discharge opening, the refrigeration system, the refrigeration system consists of the metal tubes, the evaporator is layed at the bottom of the middle box of the beverage box or the location closing to the bottom of the box, the blowing ice parts touches with the metal tube or with a small gap, the blowing ice parts moves by the power steeing. It is: the refrigerant evaporates in the metal tube in order to freezing the beverage out of the metal tube, the evaporator is not only low cost but also high heat transfer coefficient, and moreover, it is simple structure and higher guidable plot ratio.

Description

Technical field [0001] The invention relates to an ice cream machine. Background technique [0002] The ice cream machine is a device that freezes and scrapes part of the water in the beverage into ice crystals, so that the original liquid beverage becomes a semi-fluid state, so the refrigeration system and the ice scraping system are its key systems. The ice scraping system includes ice scraping parts and a power unit. [0003] Chinese patent application number is that the invention patent of 97126214.2 discloses a kind of slush machine that adopts dry type evaporator. The evaporator is a circular drum, and there is a spiral flow channel in the drum for the refrigerant to pass through. Since the liquid beverage outside the evaporator is directly frozen, this evaporator has a high heat transfer coefficient and a good heat transfer effect. However, the production process of the drum with such a spiral flow channel and the tight fit between the flow channel wall and the inn...
