Instant Chilling Plant


A) Basis Of Design

  • No. of units - One
  • Ref. Capacity of Unit – 10 TR at 5 Deg C SST & 55 Deg C SDT
  • Fluid to be chilled - Water
  • Chilled water temp. at chiller inlet - 14 Deg.C
  • Chilled water at chiller outlet - 10 Deg.C
  • Refrigerant - R-22
  • Electric supply available - 415 V, 50 Hz 3PH
  • Fouling factor for chiller - 0.0001 sq. m. / hr. deg. C / L. Cal

B ) Scope Of Supply

  • 1.0 1 NO 17 TR CAPACITY AIR –COOLED CHILLING UNIT COMPRISING OF


Benefits

  • Low cooling cost is most important benefit (about 20-25%).
  • By using ICP quality of milk is maintained against bacterial formation.
  • Quick cooling time is key advantage of Instant Chilling Plant.
  • It helps in improving milk quality, by preventing the initial increase of bacteria in the milk by quickly cooling the milk after milking or after collection.
  • We can get the milk having temperature of approximately 15°C immediately by instant chiller.
  • As mentioned above temperature is goes down from 34°C to 15°C immediately thereby quality of milk is maintained.
  • Less Power consumption cooling period is most important factor of ICP, which helps us to save chilling cost.
  • No chances of ice formation in bulk milk cooler during milk collection process, as we are not starting BMC at the time of collection.
  • After collection of the milk by instant chiller, we can start the BMCU for getting temperature from 15°C to 4°C, so ice formation in milk can be avoided.
