Curd Milk Heater Module Capacity : 3000LPH

CURD MILK HEATER MODULE Cap-3000 LPH

Basis of Design:

 Product: Whole Milk, 16.5%., Capacity: 3000 LPH, Temp Program: 3-42 +_1 deg C.

 Process Operation: Pasteurization temperature control (by PID controller) and flow rate (by mechanical flow controller in case of milk pasteuriser) will be automatic. Flow will be diverted automatically with alarm if temp is below the past temp. Sequencing of production, sanitisation and CIP will be manual. Detergent addition in the balance tank and concentration monitoring will be manual. CIP flow rate will be approximately 1.2 times of the product flow rate.

Utilities Required (Approx):

Hot Water: 4500 Lph Approx.

Total power: 5 kW, (3.7 kW Prod. Pump, 1.1 kW HW Pump) 415V, 3 PH, 50 Hz

Process water: 5500 LPH during CIP

CIP flow: 5500 LPH Instrument Air, 6bar: 625 NL/Hr.

• The volume of the storage (tank) for compressed air should approximately 6 times the required capacity/h.
