Medium-sized FD dryer
The HTFD type (350L, 500L, 750L, 1000L, 1200L) is mainly suitable for small and medium-sized enterprises, with high added value, small production capacity, and high quality products, such as health products, cosmetics, Chinese herbal medicine, etc., for freeze-drying deep processing. Drying area, moisture treatment, etc. are more suitable. The ice melting process uses hot shelling and warm water defrosting, and after the second cycle, it melts for less than 20 minutes and is discharged.
Workshop Design Cases
Prepare to freeze the warehouse
6-8 hours per batch, fully meeting the 24-hour freeze-drying production process, using a "first in, first out" cycle.
Suspended material truck rail transportation
The material tray of the hopper car is equipped with predetermined weight of raw materials, which enter the drying device. After drying, the hopper car exits the discharge, and the system is simple, hygienic, and safe for feeding.
HTFD type freeze-drying machine
Automatic/manual control, each drying cycle only needs to close the cabin door, set the process parameters, press the start button, and enter the drying process.
Heating system
Radiation heating, with a temperature range from room temperature to 120 ℃, and precise control of the drying process, ensures high-quality product quality.
Vacuum system
By selecting an imported vacuum pump with high efficiency and large flow rate, the required vacuum degree can be achieved within 15 minutes.
Ice melting system
Batch ice melting, utilizing batch interval time, ends the ice melting within<30min between discharge and input time, without occupying drying time.
Refrigeration system
Adopting a large unit parallel system, each condenser shares a common system, with staggered operation and energy saving and consumption reduction.
PLC/PC control system
The Siemens PLC module control system is selected to ensure the optimal working state of the freeze-drying process, material freezing, drying, heating medium, vacuum, and refrigeration systems. Remote devices can also be installed to achieve remote control.
