Food freeze dryer utilizes FD freeze drying technologyFreeze crystallize water containing foods and then sublimate and dry them in a vacuum environment to remove moisture, resulting in freeze-dried foods with very little water content. They are widely used in various fruit and vegetable freeze-drying and meat freeze-drying processes. Among them, seafood abalonecontainHigh protein, low-fat foods，taste delicious，nutritious.In order for abalone to be stored at room temperature for a long time without damaging its original nutritional components, color, aroma, taste, and body shapeThe food freeze dryer is applied to the freeze-drying processing of seafood and abalone, changing the traditional drying or sun drying methods.

Selected fresh abalone undergoes processing and cleaning, followed by pre-treatment processes such as cooking, cooling, soaking, color protection, and draining. It is then loaded onto a tray and placed in the material compartment of the food freeze dryer for further processing3~5Hour by hour-45Low temperature in-situ pre freezing at ℃, followed by10One hour drying, temperature controlled at-30~+30℃, the vacuum degree is controlled to40PALeft and right, dry to remove stray water, and then perform analytical drying operation8About an hour, the sublimation drying temperature is controlled at35~60℃, the vacuum degree is controlled to30PALeft and right, remove bound water to obtain water content2~5%Dried abalone. Because abalone crystallizes into solid water at low temperatures in a vacuum environment and directly sublimates into a gaseous state for removal, it does not damage its original structure or undergo oxidation reactions, greatly preserving its original structure and nutritional components. After being processed by a food freeze dryer, it contains very little water and can be stored at room temperature for a long time. It also has good rehydration properties and can restore the original appearance of abalone after rehydration.

The freeze-dried abalone processed by a food freeze dryer changes the traditional processing method and provides a consumer market for more additive free, natural, and nutritious abalone food, making it more convenient for people to enjoyDelicious taste and rich nutritionAbalone.Food freeze dryers are widely used simultaneouslyUsed for processing and production of vegetable freeze-drying, fruit freeze-drying, meat freeze-drying, fish freeze-drying, tea freeze-drying, and traditional Chinese medicine freeze-drying.
