This invention will benefit the SMEs because they may use the immersion freezer to store a maximum volume capacity of 1,000 liters. This looks bigger than the usual home freezer or chest freezer of a grocery store. The freezing capacity can be up to 60 kilograms per hour. Water soaked with salt is being used in the freezer which brings cool air through its cooling coils then it lets the contents to be frozen. Business owners are advised to seal the food properly to prevent brine spilling into it. Just like a fridge, temperature can be adjusted based on the food requirements.
