blast freezer
The noise level emitted by a blast freezer can vary depending on the specific model and its design. Generally, blast freezers can produce noise levels between 70 to 90 decibels while in operation. It is recommended to check the manufacturer's specifications for the exact noise level of a particular blast freezer model.
There are several compartmentalized freezers, including the DGS Ultra-Low Temperature Blast Freezer Chamber Series (DGS-65A), the AH Series Chiller (AH003), the OC Compartmentalized Multi-Temperature Logistics System (01), and the EK Series-Counter-Style Freezer and Chiller (EK180).
The usual temperature in a freezer is at or below 32 degrees. Most home freezers are set at 28 degrees. This will put the food temperature at about the same as the freezer temperature.
You can put your gelato in a regular freezer, you may just have to wait a few more hours, such as overnight because a blast freezer quickly freezes the gelato in a short amount of time so you can eat it quicker. ( about 5 min)
To calculate the correction factor for a freezer, you need to compare the setpoint temperature of the freezer to the actual temperature inside. The correction factor is the difference between the setpoint and actual temperature. Adjust the setpoint temperature by this correction factor to ensure the freezer maintains the desired temperature consistently.
The normal freezer temperature is typically set at -18 degrees Celsius.
To make your freezer colder, you can adjust the temperature settings by turning the dial or pressing the buttons to a lower temperature setting. This will help maintain a colder temperature inside the freezer.
If it's been in the freezer long enough, it will have the same temperature of the freezer. Thermal energy is transferred from warmer objects to cooler objects until there is an equilibrium, which in this case is the temperature of the freezer.
A blast freezer becomes necessary for making gelato in the event the gelato is not going to be served right away. This allows the gelato to be frozen below the ability of most freezers and keeps the product useable longer.
Freezer trucks maintain a low temperature by being very well insulated. Freezer trucks use the same concept as a stationary freezer to work but they are specially designed to move about.
Normally, the ice cream out from machine (ice cream batch freezer) is about -6 degrees to -8 degrees. The best temperature for hard ice cream / gelato is about -18 degrees. Use one unit blast freezer for fast freezing ice cream. It can let the ice cream fast reach to target temperature to prevent crystallization. And the final step is storage ice cream in the display freezer, about -16 to -20 degrees. MEHEN FOOD MACHINE
