Application Analysis of Dynamic Ice Slurry System in Precooling of Fruit and Vegetable

Abstract

Ice slurry precooling technology is a preservation technology that has unique advantages in the preservation of fruits and vegetables. It can make fruits and vegetables quickly drop to a suitable storage temperature. This paper summarizes the preparation methods of ice slurry, including the wall scraping method, undercooling method, vacuum method, fluidized bed method, and direct contact method. The wall scraping method, which has been widely used in industry and commerce, is the main method to design the dynamic ice slurry system between the buffer of fruit and vegetable air conditioning storehouse. Finally, this paper summarizes the characteristics and application of ice slurry precooling and makes a summary and prospect.
