Vacuum Freeze Dryer Machine|Chips Dates Meat Freeze Drying Oven

Vacuum freeze dryer machine full name vacuum freeze dryer, also known as freeze dryer, is a drying technology that uses the principle of sublimation to dehydrate materials. After the material is rapidly frozen, it is heated in a vacuum environment to analyze the water in the material, and then the water is frozen and stored by the water trap, and the material warehouse is kept in a dry state until the moisture in the material is completely sucked out to achieve vacuum freezing. The freeze drying machine can process chips, dates, berries, potato, banana, sweet potato, mushroom, carrot, green beans, maize or corn, tofu etc

Suitable scope of the vacuum freeze dryer machine:

1. High-grade instant noodles and convenient rice ingredients in the convenience food field. Dried, dried diced meat, shrimp, eggs and shallots, carrots, parsley, etc. have been used in color, aroma and taste.

2. In the instant soup field, all kinds of soups with lyophilized foods are mixed with boiling water, which is delicious, convenient and hygienic.

3. In the field of granular vegetables, a variety of freeze-dried vegetables are selected, which are reasonably matched according to the nutritional needs of the human body to form granules. This vegetable granule contains natural chlorophyll, vitamins, carotene and essential trace elements, which are especially suitable for children, the elderly, patients and some people who have difficulty eating vegetables.

4. Freeze-dried dehydrated vegetables: Carrots, rapeseed, mushrooms, onions, garlic, green beans, corn, spinach, etc.

5. Freeze-dried dehydrated meat: Beef, pork, chicken, etc.

6: Freeze-dried dehydrated aquatic products: Shrimp, fish fillets, crab meat, etc.

7: Fruit and vegetable chips: Because the freeze-dried food has almost no water-containing porous structure, it is both brittle and crisp. Using this property to make flaky fruits and vegetables freeze-dried products (tablets, pieces, grains) is a good high-end leisure. food. Its color, aroma, taste and preservation time are incomparable for the chips made by other processes on the market.

Advantages of the fruit vacuum freeze dryer machine:

1.The nutrients are basically unchanged. Because it is dried under low temperature and poor (vacuum) conditions, the nutrients are almost undestroyed, especially heat sensitive substances.

2.The shape is basically unchanged. Because it converts water directly from the solid state into a gaseous state, the food structure does not change, but the space occupied by ice crystals forms voids.

3.The color is basically unchanged. Since the drying is carried out under low temperature and poor conditions, the physical and chemical properties of the food change little, mainly because the ability to respond to visible light does not change much after rehydration. The possibility of oxidation and enzymatic change is small, so the original color is easy to maintain.

4.The fragrance is basically unchanged. Because the fragrant ingredients in the food remain in the amorphous concentrated part during the freezing process, the scent does not escape with the ice crystals vaporized.

5.The quality of solid materials is basically not lost. Since the moving speed of the sublimated water vapor is small, the object is basically at a static state, and the mass loss of the solid matter is negligible.

6.Excellent rehydration and easy to eat. Since the water leaves a large amount of pores after drying, the rehydration is good, up to 95%, and the water is frozen and frozen, and can be completed in a few seconds to several tens of seconds.

7.Easy to store and long shelf life. Due to the high dehydration rate, no preservative is needed, and there is a long shelf life at room temperature.If the packaging is good, the shelf life can be more than five years. The product is light in weight, does not require cold chain storage, is convenient to store, and has low recurring cost.
