Seafood freeze-drying machine uses FD freeze-drying technology to freeze and crystallize water containing foods, and then sublimates and dries them in a vacuum environment to remove water, resulting in freeze-dried foods with low water content. It is widely used in various fruit and vegetable freeze-drying and meat freeze-drying processes. Among them, seafood abalone contains high protein and low-fat foods, with a delicious taste and rich nutrition.
Seafood freeze dryerIt is the use of FD freeze-drying technology to freeze and crystallize water containing foods, and then sublimate and dry them in a vacuum environment to remove water, resulting in freeze-dried foods with low water content, which are widely used in various fruit and vegetable freeze-drying and meat freeze-drying processes. Among them, seafood abalone contains high protein and low-fat foods, with a delicious taste and rich nutrition. In order to preserve abalone at room temperature for a long time without damaging its original nutritional components, color, aroma, taste, and body shape, a food freeze-drying machine is applied to the freeze-drying processing of seafood abalone, changing the traditional drying or sun drying methods.
The selected fresh abalone undergoes processing and cleaning, followed by pre-treatment processes such as ripening, 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 3-5 hours of low-temperature in-situ pre freezing at -45 ℃, followed by a 10 hour drying process. The temperature is controlled at -30~+30 ℃, and the vacuum degree is controlled at around 40PA. The dried abalone is then subjected to analytical drying for about 8 hours, with sublimation drying temperature controlled at 35~60 ℃ and vacuum degree controlled at around 30PA. After removing bound water, a freeze-dried abalone product containing 2-5% water is obtained. 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, preserving its original structure and nutritional components. After being processed by a food freeze dryer, abalone can be stored at room temperature for a long time with low water content and good rehydration properties. After rehydration, it can restore the original characteristics of abalone.
The freeze-dried abalone processed by seafood freeze-drying machine changes the traditional processing method and provides a more additive free, natural, and nutritious abalone food for the consumer market, making it more convenient for people to enjoy the delicious and nutritious abalone. Food freeze-drying machines are widely used in the 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.
