In addition to gas
Degassing is the removal of dissolved/trapped gases in a liquid or product. Vacuum devices can remove gases from liquids, improve their physical properties, improve product quality, and avoid cross-contamination or corrosion.
Here is a simple list of USES:
For oil removal, improve purity (hydrocarbon oil, insulating oil, turbine oil, brake fluid, hydraulic brake oil, etc.)
Remove excess gas that may harden or reduce the quality of the product
The polymer is degassing in the extruder to achieve higher product quality or to get no foaming
Remove air from water in medicine, food and boiler.
Add and/or transfer of material
When the milk and paste are injected into the pipe, the air is expelled. This can be done by adding a small liquid ring pump or rotating impeller pump. Vacuum pump is used to add the liquid to the box, then it is expelled through the compressor, so that the transfer of liquid can be achieved through a series of vacuum pumps.
Crystallization is the evaporation and cooling of an oversaturated liquid, forming a crystal. These crystals are convenient for carrying, storing and selling. For this kind of application, our vacuum pump is an ideal product that can be used to control the evaporation/cooling rate in all pressure ranges and reduce the production cost by lowering the boiling point of liquid.
These applications include:
Concentration: distillation, discharge, radioactive waste, black liquor, sugar, beets
Restoration of gold-plated raw materials, photographic solution
Production of ammonium nitrate and sodium hydroxide and so on
Crystal sugar, salt, health ball, aniline, urea, calcium sulfate, potassium carbonate, amino acids, penicillin and antibiotics
Fine chemicals, medical and aromatic chemicals are used in reactors. Vacuum devices are used to reduce/control reaction temperature, remove reactants, reduce costs and control/improve product quality, and capture products.
Many chemical reactions and the application of dry pump techniques, including medical semi-finished products, neutralization and adsorption chemical reactions, hydrocarbon and other chemical product desorption/cracking and compound synthesis.
Drying (tray, rotating, turning, conical and freeze-dryer)
Drying is a process with low cost and relatively low temperature. By reducing the vacuum degree, the liquid is vaporized from the solid. The biological component or active ingredient is not damaged/reduced/oxidized. Dry the medical/biological products, remove solvents and water, and especially require that the final drying part be less than 1 torr. After drying, the remaining parts are granulated and made into tablets. The remaining humidity level is low, which can prolong the shelf life of the product.
Distillation is the separation of two or more layers or parts of different temperatures, pressures, components and phases. As the distillation column approaches equilibrium, each part has a different concentration, which can be separated from the mixed species. The distillation column provides a pressure to separate the different liquid components, separating the vacuum and the temperature.
The vacuum system removes noncondensate, water and light hydrocarbon from the system, allowing the material to be processed through the distillation column to realize the separation. For the expulsion of gas from the distillation column to A condenser, liquid return distillation tower, in part from, typical applications in fatty acids, one-component glycerin hydrochloric acid, vitamins (A, E), oil, grease, paraffin wax, pesticides and plasticizer, etc.
