Product details
Large-capacity vacuum freeze dryers are suitable for processing plants for large-scale freeze-drying production lines. Its characteristics are that it is suitable for the production of single variety, complex products with huge output and sufficient raw materials, especially suitable for the production of pulp and granular products. Adopt high-quality materials widely accepted in the industry and import configuration of main components. At the same time, it is equipped with a high-tech manufacturing process that meets international standards.
Operating principle of large capacity vacuum freeze dryer:
Vacuum freeze-drying technology (referred to as freeze-drying technology) is to study the process, characteristics and laws of heat and mass transfer in the drying of frozen materials in a vacuum environment. It is an interdisciplinary comprehensive technology. The development of freeze-drying technology needs the support of vacuum refrigeration, heating, mechanical transmission, automatic control and other technologies.
The principle of vacuum freeze-drying is based on the three-phase diagram of water. Below the triple point pressure of water (610.5Pa), there is no liquid water, and solid ice can be directly sublimated into water vapor. If a certain amount of heat is provided at this time, Ice can absorb heat and sublime into a gaseous state, thereby dehydrating the material, so it is also called freeze-sublimation drying.
Advantages of large capacity vacuum freeze dryer:
1. High efficiency
The refrigeration system can adopt high-quality imported compressor units according to customer requirements, with high refrigeration efficiency and convenient maintenance.
2. Stable performance
The vacuum system adopts the dual system design of the pre-pumping unit and the maintenance unit, which improves the stability and durability of the system operation.
3. Multiple protection
Water shortage and power failure protection, lack of compressed air alarm, bass operation.
The equipment is easy to realize automatic control, which simplifies manual operation and management. This series of freeze dryers adopts standardized production, which is satisfied with the processing and production of various foods, Chinese herbal medicines and industrial raw materials. For the needs of large-scale production of freeze-dried products, we can provide customers with whole-plant solutions, including pre- and post-processing of materials and professional freeze-drying solutions.
