Spray Coolers

Nozzle Atomizer Type Spray Coolers

Product Details:
  • Efficiency: 99.95%
  • Minimum Particle Size: 0.5
  • Applications: chemical, food, and pharmaceutical industries

Nozzle Atomiser Type Spray Coolers is used to spray the melt formed particles of spherical shape by spraying the melt into a cooling chamber through which ambient or cooled, low-temperature air is passing.

These are applied in the chemical, food, and pharmaceutical industries. This has proven to be a most convenient method of transforming melted feedstock into free-flowing particulates of controlled particle size.

Rotary Atomizer Type Spray Coolers

Approx Price: Rs 10 Lakh / Piece 
Minimum Order Quantity: 1 Piece
Rotary Atomizer Type Spray Coolers is defined as a process by which a melt is formed into particles of spherical shape by spraying the melt into a cooling chamber through which ambient or cooled, low-temperature air is passing. Rotary (wheel) atomisers and nozzles are used to spray the melt. Spray cooling finds applications in the chemical, food, and pharmaceutical industries. It is a most convenient method of transforming melted feedstocks into free-flowing particulates of controlled particle size.

 

Reference Products: spray cooler is used for following products

  • Fats Glycerides Hydrates
  • Inorganic/organic melts
  • Stearic acid/stearates
  • Glycerol Monostearate (GMS)

 

 

The selection of a spray cooling plant design depends upon the particle size specified as well as the need for post-cooling / crystallisation for the cooled product

 

Fine particle products with mean particle size 50-150 micron; co-current conical based cooling chamber with high-speed rotary atomization.

 

Coarse particle products with mean particle size 150-300 micron; conical based cooling chamber with fountain nozzle.

 

Utilising closed cycle spray cooling enables optimisation of cooling energy requirements and product quality

 

Main Components of Spray cooler-

  • Cooling Chamber
  • Conveying Duct
  • Cyclone Separator
  • Centrifugal fans
  • Heat exchanger
  • Feed tank- Jacketed
  • Feed Pump
  • Feed line and spraying nozzle
  • Instruments- Pressure Switch, SRV, Temperature controller, VFD
  • Working Principle of the spray Cooler-
  • Hot melt is sprayed in the cooling chamber consists of cool air.
  • Heat transfer takes place between the hot particle and cool air, forming a fine powder.
  • Proper cooling and particle hardening of particle take place in conveying duct.
  • In cyclone separator, air and powder get separated and powder is discharged through the rotary valve.
  • Air containing less amount of fine particles comes to centrifugal fan.
  • The air gets chilled in the heat exchanger and again supplied to the chamber.
  • Salient features of spray cooler manufactured by Supreet-
  • Single point collection of powder. This ensures less handling of finish product.
  • No mitre bends in the ducting avoids material deposition in the system.
  • Pressure from 10 kg/cm2 to 200 kg/cm2 can be achieved.
  • Thick slurries can be handled and sprayed by giving high pressure.
  • Very low maintenance is required (periodical cleaning of heat exchanger tubes).
  • All valves are jacketed only- avoids external heating of valve body during start up.
  • The total plant is automatic and no man interference is required. Only one man for the powder collection is required
