Vacuum in chemical processing industry play a vital role and is seen in variety of applications. Most commonly seen usage of vacuum is in distillation and drying applications. With the FDA norms coming in, technology is now shifting from the legacy based liquid ring vacuum pumps to dry type vacuum pumps.
HHV Pumps offers a widespread variety of pumps ranging from the conventional rotary vane principle to complete dry vacuum pump.
Some of the major applications are:
-
Effluent Treatment
Column Distillation
Column Distillation method is used when the mixture contains one more fractional material. Packed columns are used to separate the material under vacuum.
-
Filtration
Agitated Nutsch Filter and Dryer (ANFD)
ANFD is an advanced system of solvent separation in the reactor. Vacuum Filtration & Drying through a membrane helps in saving energy. In the conventional system, Solvent Distillation and Drying are done separately and it requires more time.
-
Formulation
Capsule Filling
Shell of capsules are held under vacuum while the drug gets filled in from the other side
Deaeration/Degassing
Removal of trapped air molecules from high viscous materials like tooth paste, lotion, moisturiser etc.
Packaging
Create a sterile atmosphere with the help of vacuum
-
Material Transfer
Sludge, Liquid & Powder Transfer
Vacuum helps in transporting the material (Powder, Sludge or Liquid) from one place to another. For example, transporting of fine sugar powder from silo to the reactor for syrup/further manufacturing process.
-
Vacuum Distillation
Short Path Distillation
High vacuum distillation is mainly applicable to distil materials that are heavy in molecular weight. One of the well-known applications is Vitamin E (Tocopheraol), Fatty acid extraction from Soya, Corn, Palm Oil.
Agitated Thin Film Evaporator (ATFE)
ATFE method of distillation is used when the distillates molecular weight is less than 400 Gms/mole
Kettle – Column Distillation
Used during recovery of solvent after the reaction process in API plants
-
Vacuum Drying
Freeze Drying
Dehydration of sensitive substances like biological samples, high value chemicals, vaccines etc. under vacuum in a closed chamber or smaller vials connected to a vacuum system
Tray Dryer
Complete drying of material under vacuum in placed on trays kept inside a vacuum chamber. Drying under vacuum ensures 100% removal of moisture from the substrate material.
Roto-Cone Dryer
Complete drying of material under vacuum in a rotatable conical shaped vessel. Drying under vacuum ensures 100% removal of moisture from the substrate material.
Rotary Tumbler Dryer
Complete drying of material under vacuum in a rotatable cylindrical shaped vessel. Drying under vacuum ensures 100% removal of moisture from the substrate material.
