In medium and large egg tart processing factories, there are multiple freezing machines to transport the finished egg tart shells to the freezer machine. After quick freezing, the taste of the egg tart is maintained.
After freezing, the egg tart shells can be stored for a longer period of time in the freezer, and consumers can still eat the egg tart skin with the same taste after a few months.
How does the Freezer Machine Work
The freezer machine, also known as a freezer or freezer unit, is an appliance used to lower the temperature of food to below their freezing point, typically to preserve them for longer periods. The basic principle behind the functioning of a freezer machine is the removal of heat from the enclosed space, thereby reducing the temperature and causing the items inside to freeze.
- Compressor: The process begins with a compressor, which is typically located at the back or bottom of the freezer. The compressor is powered by electricity and its main function is to compress and increase the pressure of a refrigerant gas.
- Condenser: Compressed refrigerant gas, which is at high pressure and temperature, flows into the condenser coil behind the tart shell freezer. The heat is then dissipated, and the refrigerant condenses into a high-pressure liquid.
- Expansion valve: High-pressure liquid refrigerant passes through the expansion valve, which restricts the flow of the refrigerant and reduces its pressure, allowing it to expand rapidly.
- Evaporator: After the refrigerant expands, it becomes a low-pressure gas and absorbs heat from the surrounding environment, including the contents of the freezer. This is the cooling process. The evaporator coil provides a large surface area for heat exchange, reducing the temperature inside the egg tart shell freezer machine.
- Fan: To ensure efficient cooling, most freezers have a fan that circulates air over the evaporator coils. This helps to distribute the cold air throughout the freezer compartment, maintaining a consistent temperature and preventing hot spots.
By continuously cycling the refrigerant through these processes, this egg tart shell freezing machine can maintain a consistently low temperature, allowing food and other items to freeze and remain preserved for extended periods. If you want to know more about this machine, welcome to contact us.
