The quick-freezing process includes fruit selection→sepal removal→fruit washing→sterilization→rinsing→water control→arrangement→quick freezing→packaging→refrigeration.

2. Fruit washing and disinfection. Put the strawberries into the strawberry washing machine for cleaning. The strawberries can be rubbed and washed to remove impurities and pesticides on the surface of the strawberries.

Before placing on the plate, the water on the surface of the fruit should be controlled and dried, or the strawberry air dryer generally used in industrial processing should be used for air drying, so as to avoid water or adhesion on the surface of the frozen product. Then put the fruit flat on the plate for quick freezing, and some need to add sugar before quick freezing. During quick freezing, keep the temperature below -25°C until the core temperature reaches -15°C.

Send the packaged quick-frozen strawberries to the freezer for storage. It can be refrigerated for 12-18 months under the condition of -18℃ in the cold storage.
