Description

Air-entrapping type ice cream machine

Technical Field

The utility model belongs to the technical field of ice cream machine, specifically a gas filling type ice cream machine.

Background

At present, the making process of ice cream is generally as follows: adding liquid slurry into a refrigerating cylinder of the ice cream machine through a feeding cylinder of the ice cream machine, refrigerating and condensing an evaporator in the refrigerating cylinder, and stirring the liquid slurry by a stirrer in the refrigerating cylinder; after a certain time, the liquid slurry is solidified and formed to form the ice cream, and the formed ice cream is ejected through the discharging switch. However, the taste of the ice cream is not good because the ice cream is not puffed, and the ice cream made of the same number of raw materials is less than that made by puffing, so that the raw materials are puffed firstly and then put into an ice cream machine at present, when a customer wants to eat the ice cream, the ice cream is made through a discharge port, and because the raw materials are not puffed during the ice cream making process, the taste is still unsatisfactory, and the puffing effect is not ideal.

In order to solve the above problems, some ice cream makers use air added into a cooling cylinder to achieve the expansion effect of ice cream, but the following problems are generally encountered: (1) the air-entraining device is usually started immediately after the ice cream machine is started, namely the air-entraining device, the compressor and the stirrer are started simultaneously, and because the slurry just added into the refrigeration cylinder is liquid slurry and has low viscosity, the added air is difficult to be absorbed by the slurry and basically escapes from the slurry, the air entraining has little expansion effect on the ice cream at the moment, and even the feeding is possibly influenced; (2) the air-entrapping device continuously entraps air into the refrigerating cylinder at the maximum flow rate, so that excessive air is easily injected into the ice cream machine, and the prepared ice cream has high expansion rate, soft tissue and poor stability.

In order to facilitate better understanding of the utility model, the process and characteristics of making ice cream by the ice cream maker are introduced below:

during the preparation process of the ice cream, the ice cream slurry in the refrigerating cylinder of the ice cream machine is continuously stirred by the stirrer while being refrigerated and condensed, the temperature of the ice cream slurry is gradually reduced, and the ice cream slurry is gradually condensed into a semi-solidified state with fine and smooth taste. In the process that the ice cream slurry is changed into a semi-solidified state, the resistance borne by the stirrer is increased along with the gradual increase of the forming proportion, and the working current of a stirring motor of the stirrer is increased due to the increase of the load; along with the forming output of the ice cream, the hardness of the ice cream slurry is reduced, the temperature and the rotating speed are increased again, and the current value is adjusted to be small. When the set parameters, such as temperature, rotating speed, current or working time, reach the set values, the ice cream machine stops refrigerating; when the set stop time is reached or the material beating work is carried out in the middle, the ice cream machine enters the refrigerating state again.
