Freeze dryer is a modern food preservation equipment that, after special technical treatment, can freeze and evaporate the moisture in food, keeping the original nutritional content and taste of the food. It is widely used in food processing, pharmaceutical industry, laboratories and other fields.

1. Working principle

The core working principle of a freeze-drying machine is to utilize low-temperature solidification and water evaporation in a vacuum environment. When food is placed in a freeze-drying machine, the low-temperature environment will quickly freeze the moisture in the food and produce ice crystals. Next, in a vacuum environment, through the heating process, ice crystals will directly transform from solid to gas, which is called sublimation. During the sublimation process, the water in the food is evaporated while maintaining its original structure and composition, achieving the effect of preservation.

2. Usage

Using a freeze-drying machine is very simple. First, put the food that needs to be preserved inside the machine. Next, start the machine, set the temperature and time, and the machine will automatically start working. Throughout the process, the machine will automatically monitor temperature and vacuum level to ensure that the freeze-drying process of food can proceed according to the set requirements. Once the freeze-drying process of the food is completed, the machine will sound a prompt, and you can take out the food for packaging and storage.

3. Advantages

Compared to traditional food preservation methods, freeze-drying machines have many advantages. Freeze dryer can maintain the original nutritional content and taste of food, making it less affected by heat treatment and freezing, making it healthier and more delicious. Secondly, freeze-drying machines can greatly reduce the volume of food, reducing storage and transportation space, making it easy to carry and sell. In addition, freeze-dried food does not require the addition of preservatives and other chemicals, making it safer and more reliable.

4. Application field

Freeze drying machines are widely used in various industries. In the field of food processing, freeze-drying machines can freeze dry fruits, vegetables, meat and other ingredients, used to make various dried fruit snacks and health products such as dried fruits, dried vegetables, and dried meat. In the field of medicine, freeze-drying machines can be used to make herbal powders, drug tablets, etc., making drugs easier to store and take. In the laboratory field, freeze-drying machines can be used to prepare samples, preserve cells and microorganisms, etc. In the field of outdoor sports, freeze-dried food, as a compact and portable food, is highly favored by mountaineering and travel enthusiasts.

In summary, freeze-drying machine is a multifunctional, efficient, and energy-saving food preservation equipment. It is simple and convenient to use, can maintain the original quality and nutritional content of food, and is widely used in food processing, pharmaceutical industry, laboratories and other fields. If you also want to taste the charm of fresh food, you may consider purchasing a freeze-drying machine, which will bring convenience and health to your life.
