Freeze dryers for sale worldwide. These are drying equipment or dehydration equipment that remove water from materials. The difference between freeze dryers and other dryers is that the water in the material is transferred from a solid state (ice) to steam, while other drying methods are from liquid water to steam.
The advantage of freeze drying technology is to optimize the quality of freeze dried materials. Freeze dryer for sale is mainly applied to process fruits and vegetables. The food that is sublimated and dried by the food freeze dryer has almost no nutrient loss. After freeze drying, the shape will not change, and the color will not change. It can be stored for a long time without adding preservatives and additives.
Freeze dryer for sale has been widely used in the fields of injection, protein, bacteria and other medicine or biological field.
Nowadays, food freeze dryer for sale is developing rapidly. As the name implies, the vacuum freeze dryer has both vacuum equipment and refrigeration equipment. At the same time, it also needs heating equipment to provide the required heat for product sublimation. Since the internal space of the main body of the freeze dryer for sale is in a vacuum state during operation. There is pressure difference between the inner and outside atmosphere is -0.1Mpa. Therefore, the vacuum freeze dryer is a negative pressure container. In order to enable the vacuum freeze dryer to withstand the pressure difference, generally speaking, the container is designed in a cylindrical shape to maximize its compressive strength. If a rectangular design is adopted, reinforcing ribs must be used on the outside of the rectangular chamber to ensure its compressive strength.
There are two types of freeze dryer for sale:
1. According to the output capacity, there are experimental freeze dryers and production freeze dryers. The experimental freeze dryer requires complete functions, low noise, and can use single-phase power. The production freeze dryer requires large production capacity, high production efficiency, energy saving and environmental protection.
2. From the point of use, there are pharmaceutical freeze dryers, food freeze dryers and household freeze dryers. Pharmaceutical freeze dryers are required to comply with FDA and GMP; food freeze dryer for sale is required to meet food-grade hygiene standards and economical and efficient; household freeze dryers require small size, low noise, and energy saving.
