SRD series freeze dryer

  • Detail
  • Parameters
  • Large area evaporator design improves the purification and drying efficiency of the equipment.

  • Compared with the traditional equipment, the energy consumption of the whole machine is more than 30%.

  • Fully closed wood packaging and independent forklift hole design to ensure the safety of product transportation.

  • Advanced and efficient stainless steel plate heat exchanger is combined with traditional fin evaporator, which is more suitable for domestic use.

  • The maintenance cost is low and the replacement is convenient. The display of the control panel of the whole machine is complete and clear, the operation is simple, and the equipment starts automatically to save energy and increase efficiency.

  • The unique design of the cyclone type orifice gas-water separator adopts the unique orifice trap capture technology to lock and discharge the condensate and mixture firmly, so as to ensure the stability of the dew point of the product gas.

  • The condenser with large area and small fan ratio is used to ensure the superheat of the refrigerant, and the pressure controller is equipped to start and stop the fan, so that the superheat of the refrigerant is stable under different ambient temperatures, and the operation cost is reduced.

  • The precooler adopts stainless steel plate heat exchanger, which has high heat exchange efficiency, small temperature difference between air inlet and outlet, strong anti-corrosion ability, effectively absorbs the heat of air, reduces the load of evaporator, and enhances the processing capacity of equipment.
