Industrial Freeze Drying Systems

HUCHUAN® Industrial Freeze Drying Systems save space, maximize productivity and reduce production costs. Carefully designed according to your site layout, our industrial freeze drying system will be perfectly connected with your production process.

1.Overhead rail transport system

The operator quickly transports the product to the required area by means of a sliding trolley on the overhead rail. The whole process is rationally designed, and the freezing room, drying chamber and product pallet loading and unloading areas are connected by the overhead rail, forming a close production process, saving labor and time.


2.Product freezing system

Products are quickly frozen in the freezing room, and a 6~8 hour preparation shift can provide enough freeze-dried products for 24 hours. Freezing adopts the principle of “first in, first out”.


3.Drying sublimation system

Automatic control of drying cycle for each batch. Just close the door of the drying chamber, set the process parameters and press the start button to enter the drying process, minimizing manual intervention and supervision.


4. Heat supply system

The controlled temperature range from room temperature to 90°C is precisely monitored and controlled to optimize the drying process.


5. Vacuum system

High efficiency, high flow vacuum pumps typically reach the required vacuum level in less than 15 minutes. For products with a low freezing point, even more precise control is possible.

High efficiency, high flow vacuum pumps typically reach the required vacuum level in less than 15 minutes. For products with a low freezing point, even more precise control is possible.


6. Refrigerationg system

Adoption of industrial compressor with high efficiency cooling. When multiple units are operated in parallel, each condenser can share a common system, staggered operation, significant energy saving.


7.De-icing system

By using water flushing batch type ice melting, utilizing the batch interval time, the ice melting will be finished in about 40min without taking up the drying time. The water flushing de-icing system is low cost and easy to operate.


8.Control system

Advanced PLC industrial control system, support manual/automatic switching, with real-time operation parameter control and process curve printing function, all data can be stored and retrieved. The control system can ensure that the freezing, drying and related heating, vacuum and cooling systems work efficiently and harmoniously, so that the machine is in the best operating condition.


Standard Features


  • All subsystems are independently designed, shipped separately and assembled on site.
