The principle of operation of the ice cream maker
Ice cream became popular and affordable in the second half of the 20th century, when industrial production was adjusted. The first recipe of frozen delicacy to Europe from the countries of the East was brought by the great traveler Marco Polo, and the technology was improved on the island of Italy in Sicily. A modern product to prepare in catering. When cooking, in addition to natural ingredients, manufacturers add dyes, food additives, preservatives and other harmful ingredients. Therefore, many users think about how to prepare a fruit dessert at home, how the ice cream maker works and works.

Cooking technology
In the XIX century, ice cream was prepared using wooden tubs: a container with a mixture was put into it. Then they covered salt with ice. After that, the master set in motion the device, slowly turning the knob. Constant intensive rotation prevented the formation of large crystals. As a result, the mixture was cooled evenly, and the consistency became homogeneous. If the ice melted, his stock in the tub replenished. The cooking process took about 60 minutes.
The technology itself has not changed over time, only the cooling system has been improved: the mechanical design with a handle was replaced by an electric motor. A bucket of salt and ice replaced a double-walled tank, between which a coolant is installed.
The modern scheme of dessert preparation consists of the fulfillment of two conditions:
- Saturate the main ingredients (cream, milk, fruit, egg yolks) with air due to mixing, as a result, bringing the consistency of the mixture to a whipped mass.
- Gradually cool the emulsion to a low temperature. The mixture should be homogeneous consistency.
Types of ice cream makers
A modern ice cream maker consists of a container for mixing products. The super-powerful camera cools the mixture in a short time to a low temperature.
Manufacturers offer two main types of devices:
- Mechanical. This device must be rotated manually. As a result, the preparation time of the dessert increases. The cooler is salt and crushed ice.
- Electric. The device has an electric motor that automatically rotates the mixture using a whorl.
Electric models are semi-automatic and automatic (with a compressor).
Device and principle of operation of mechanical ice cream makers
Mechanical models are rarely available. They consist of a container into which a special bucket with ice and salt is inserted. Ice is needed to freeze the mixture, and salt - so that it does not melt.
The principle of operation of a mechanical type ice cream machine is that a person periodically manually rotate the blades, thanks to which the consistency becomes homogeneous and freezes. After 30-40 minutes, when it becomes hard to rotate, the dairy product is ready. The cost of time and effort made the technique of this type unpopular.
Device and principle of operation of electric ice makers
Electric semi-automatic freezer equipped with a container for ingredients, which has double wall, and has the following principle of operation.
- A special substance (carboxymethylcellulose) is placed in the space between the two walls, which is able to accumulate cold.
- The bowl is pre-placed in the freezer for 8-12 hours. The temperature of the freezer should be -180C ... -250WITH.
- After the container is removed and placed inside the mass for ice cream.
- Top fix mixing blade and close the lid.
- The device is ready for operation. The cooking process takes about half an hour.
Ice cream maker with a compressor is the most convenient technique for making a dairy dessert. The principle of operation is that the freezer module freezes the mixture and is inside the device, and the fluoroplastic blade mixes the products to a uniform consistency thanks to an electric motor. The devices provided electronic control with LCD display and additional functions: timer, pre-cooling, maintaining a low temperature.
Important! When choosing a semi-automatic model, consider the size of the removable bowl: it should fit in the freezer.
What ice cream to choose
Among the variety of models, the user is sometimes lost. To make it easier to focus on the market of household appliances, you can use the comparative characteristics of two types of ice cream makers - semi-automatic and with a compressor.

As can be seen from the table, automatic and semi-automatic ice cream makers have their pros and cons.You can choose a specific model depending on the requirements for the functionality of the device and personal preferences.
Manufacturers of ice cream makers offer a huge range of products. Mechanical and electrical models have a different mechanism of work. Automatic ice cream maker with a compressor is the most advantageous option. Compressor design allows you to prepare a delicious dairy dessert at minimal cost.
