Application of freeze dryer in food industry

Freeze dryer is a kind of equipment specially used for drying biological samples, medicines, food and other substances. It works by freezing water-containing samples at low temperatures and then sublimating them in a vacuum environment, thereby removing the water in the samples.

In the food field, vacuum freeze dryer is mainly used to prepare and protect food, such as coffee, tea, preserved fruits, meat products, etc., mainly in the following aspects:

1. Maintain the color, aroma, and taste of food: Freeze dryers dry food under low-temperature vacuum conditions, which can effectively maintain the original color, aroma, and taste of food. This drying method will not destroy the nutrients of the food and can maintain the quality and taste of the food.

2. Extend the shelf life of food: The freeze dryer can evaporate the water in the food, thereby reducing the growth environment of microorganisms such as bacteria, mold and yeast, and effectively extending the shelf life of the food. Freeze-dried food can be stored at room temperature for months or years without losing its original nutrition and taste.

3. Food preparation: The freeze dryer can dry coffee, tea, fruits, etc. to make food. This drying method will not destroy the original nutrients and flavor of the food, and can increase the market value of the food.

Food freeze dryers are widely used in the food industry and can provide important technologies for food processing, storage and sales to meet the needs of different consumers for food quality and shelf life.
