Drying (Tray Dryers, Rotary Dryers, Tumble Dryers, Conical and Freeze Dryers)

Drying is a low-cost, relatively low-temperature process that evaporates liquids from solids by reducing vacuum degree, without biological or active ingredients damaged, degraded, oxidized.

When drying medical or biological products, except for removing solvents and water, etc., the vacuum degree should be less than 1torr. After drying, the remainder is granular formulation, which will be compressed into tablets. The remaining moisture level is low, which can prolong the shelf life of the product.


Reproduction & Reactor Drying

Reactors are used in the fine chemical, medical and fragrance industries. Vacuum equipment is used to reduce or control reaction temperature, remove reactants, reduce costs and control or improve product quality and make product.

Pumps are used for many chemical reactions and applications, including medical semi-finished products, neutralization and adsorption chemistry, hydrocarbons and other chemical products desorption or cracking and synthesis of compounds.



Distillation is the separation of two or more layers or parts with different temperatures, pressures, compositions and phases. As the distillation column approaches equilibrium, fractions have different concentrations and can be separated from mixed species. The distillation column provides the gas pressure to separate the different liquid components by modifying the vacuum and temperature.

The vacuum system removes non-condensables, water and light hydrocarbons from the system, allowing the material to be separated through a distillation column. The gas discharged from the top of the distillation column is condensed, and the liquid is returned to the distillation column for further separation. This is typically used in fatty acids, one-component glycerol hydrochloric acid, vitamin (A, E), oil, grease, paraffin, pesticides and plasticizers, etc.



Degassing is the removal of dissolved/retained gas in a liquid or product. Vacuum equipment can remove gases from liquids, improve their physical properties, improve product quality and avoid cross-contamination or corrosion.

Degassing Applications

Degassing oil to improve purity (hydrocarbon oil, insulating oil, turbine oil, brake fluid and hydraulic brake oil, etc.)

Degassing glues, pastes and paints to remove excess gas that can lower product quality.

Degassing polymers in extruders for higher product quality or for foam-free parts.

Degassing water in medicine, food and boilers.


Crystallization & Vaporization

Crystallization is the evaporation and cooling of supersaturated liquids to form crystals. These crystals are convenient to carry, store and sell. for this application, our vacuum pumps are perfect for controlling evaporation/cooling rates over all pressure ranges, reducing the boiling point of liquids so as to reduce manufacturing cost.

These applications include:

Concentration: distillation, discharge, radioactive waste, black liquor, sugar, sugar beets.

Restoration of gold plating raw materials and solutions for photography.

Production of ammonium nitrate and sodium hydroxide, etc.

Crystal sugar, salt, sanitary balls, aniline, urea, calcium sulfate, potassium carbonate, amino acids, penicillin and antibiotics.


Filling and or Material Transfer

When milky or paste product is injected into the pipeline, it is necessary to discharge the air inside. This can be done by a small liquid ring pump on the dispenser or by a rotating impeller pump to complete.
