What is the drying material of the freeze dryer

As a core component of compressed air post-treatment equipment, the realization of its drying function depends on the material selection and process design of key components. The oil-free compressed air output by Granklin air compressor puts forward higher requirements for cleanliness and corrosion resistance on the materials of supporting drying equipment.

1. Material of core drying parts
The evaporator and precooler of a freeze dryer are the core components to achieve heat exchange, and are usually usedStainless steel or high-purity aluminumMade. This material has the following characteristics:

  1. corrosion resistance: It can resist the corrosion of trace acid substances or condensed water that may be contained in compressed air and ensure long-term stable operation of the equipment.
  2. hygiene: The surface is smooth and free of pores to avoid impurities residue. It is especially suitable for medical treatment, food and other scenes where air cleanliness requirements are strict.
  3. heat conduction efficiency: The high thermal conductivity of metal materials can quickly complete the air cooling and moisture condensation process, improving drying efficiency.

2. Material of separation and drainage components
The built-in air-water separator and automatic drain valve in the dryer are mostly usedEngineering plastics and food grade siliconeComposite structure. These materials have:

  1. tightness: Ensure that condensed water and compressed air are effectively separated to prevent secondary carrying.
  2. low temperature resistance: Maintain elasticity in low temperatures to avoid freezing or leaking of the drain valve.
  3. non-polluting: When in contact with oil-free compressed air, it will not release any substances that may affect the quality of the gas.

3. Adaptability with Granklin compressors
Granklin air compressor outputs completely oil-free compressed air through water lubrication technology, and the supporting freeze dryer does not need to process oil pollutants, so material selection can be focused onWater corrosion resistance and high cleanlinessdirection. The overall equipment adopts modular design, and the drying parts are accurately matched with the output pressure and flow parameters of the compressor to ensure maximum system operating efficiency.

The material design of the freeze dryer is based on the characteristics of oil-free compressed air. Through the combined application of corrosion-resistant metals and food-grade non-metallic materials, it provides an efficient and clean drying solution for Granklin air compressors, meeting the needs of medical, industrial and other fields. Strict requirements for the quality of compressed air.
