Lyophilizer For Food Industry

Freeze-dried food produced by freeze dryer has "many benefits"

Vacuum freeze-drying technology is widely used in the pharmaceutical industry. It can significantly improve the quality and grade of products. Western medicine freeze-drying has been developed in China. Many large pharmaceutical factories have freeze-drying equipment. In terms of traditional Chinese medicine, vacuum freeze-drying technology is mainly limited to the freeze-drying of a small amount of traditional Chinese medicine such as ginseng, pilose antler, yam, and Cordyceps Sinensis. In addition, freeze-drying technology is also widely used in the field of biomedical products.

Of course, vacuum freeze-drying technology has the disadvantage of high cost. Because it needs vacuum and low-temperature conditions, the freeze dryer needs to be equipped with a set of a vacuum system and a low-temperature system, so the investment cost and operation cost are relatively high. This can be seen from the fact that vacuum freeze-drying is mainly used inexpensive medicinal material. When the downstream small and medium-sized enterprises apply the equipment, they must be subject to capital affordability.

In addition, lyophilizer also has important applications in the food industry. People use sun drying, drying, freezing, salting, and other methods. After these methods have been used by humans for thousands of years, scientists found that sun drying, drying, salting, and other methods have greatly damaged the nutrition of food, and these anti-corrosion methods will bring harm to human health. The freeze-drying technology can quickly freeze at - 40 ℃, and then empty the air in the freeze-drying bin into a vacuum oxygen-free state. This is that the frozen water formed after food freezing sublimates and the food becomes a "dry" state. Compared with sun drying, air drying, and drying, freeze-drying technology completely retains the original active nutritional structure of food, and there is no need to add any chemical preservatives. Food can be stored for 3-5 years at room temperature, and the weight of freeze-dried food is usually only 1 / 10 or less of the original fresh state.

Why Freeze-dried food better

1. Retention of nutrients:
The food's moisture rapidly changes from a solid to a gaseous state at low temperatures during the freeze-drying process, shielding nutrients from being destroyed by high heat. Freeze-dried foods better retain their vitamins, minerals, and other vital components.

2. Flavor & Taste:
Because the process does not alter the food's cell structure, freeze-dried food has a higher chance of retaining its original flavor and taste. By adding water to it, food that has been freeze-dried can be rehydrated and restored to almost-fresh state.

 

3. Compact and simple to store:
Because the moisture has been removed, freeze-dried food is extremely light and perfect for storage and transit. Moreover, freeze-dried food is smaller than regular food, saving storage space.

4. Extended shelf life
Freeze-dried food contains almost no moisture, which significantly reduces the activity of microorganisms and enzymes and delays the deterioration and rotting process. This explains why, with proper wrapping, freeze-dried goods can last for years or even longer.

 

5.No additives required:

Food is kept more pure and natural since freeze-drying technology is capable of maintaining food quality on its own without the need for additional preservatives or chemicals.
