Flow pasteurizer PP 1000 EL PRO

Pasteurization is a thermal treatment of milk that destroys pathogenic microorganisms and allows products to last longer.

Product: milk / cheese
Efficiency = 1000 l/h
Pasteurization at a temperature = 75°C
Temperature cycle: 5-60-75-20-5°C / 5-60-75-20°C (heating to 32°C in cheese kettle)
Holding time: 20 seconds
Energy recuperation: 80%

Buffer tank
It maintains a constant flow during the pasteurization process and allows the preparation of a washing solution.
It contains:
- cover for view,
- inlet connection
- pressure relief valve
- spray ball for washing
- outlet butterfly valve
- probes detecting min and max levels.
Specification:
- Capacity: 80 liters
- Materials:  W.Nr. 1.4301 (AISI 304)
- Inlet connection: DN 32

Feed pump
The centrifugal pump transfers the product from the balance tank to the heat exchanger. The pump is designed to meet the hygienic requirements of
the dairy industry and provides gentle product handling. Internal structure around the impeller and mechanical seal allows simple maintenance with
no special tools needed. The pump is mounted on stainless steel feet, and cover protection is placed around the electrical motor. It is a centrifugal
high pressure and low flow pump. The flow rate is adjusted by a frequency inverter through the controller.
Specification:
- Rotor material:  W.Nr.1.4401 (AISI 316)

Plate heat exchanger
A sealed plate heat exchanger ensures efficient heat transfer. The unit has a flexible design and is easy to operate and maintain.

Max. working pressure: 10 bar
Max. design temperature: 100°C
Production:
Milk efficiency = 1000 l/h
T pasteurization = 75°C
T hot water = 78°C
Flow of hot water = 2000 l/h
T cooling water =  1°C
Flow cooling water = 2000 l/h
Thermal cycle = 5-60-75-20-5°C / 5-60-75-20°C
Energy recuperation: 80%

PIPE
Holding pipe is designed with consideration of installation efficiency and holding time.
Specification::
- Holding time: 20 seconds
- Material: W.Nr. 1.4301 (AISI 304)

FD VALVE
Pneumatic flow diversion valve diverts the insufficiently heated milk back to the balance tank at the request from the controller in case milk is
not properly pasteurized or if the pressure difference is less than 0,5 bar. Valve is EHEDG certified and designed in accordance with the highest
hygienic requirements.
- Material: W.Nr.1.4401 (AISI 316)
- Seals: EPDM

HOT WATER PREPARATION - EL
Consists of:
- water circulation pump,
- temperature probe Pt 100,
- manometer,
- safety valve
- filling valve,
- expansion vessel.
Specification:
Heating type: EL - electric heaters
Heating power: 24 kW
Working pressure: 2 bars

CONTROL PANEL STAINLESS STEEL
The control panel is made from stainless steel and has an IP65 rating. It includes a controller with a 5'' touch screen, all electrical components, an emergency button and visual signalization.

Recorder Professional
Recorder Professional records the temperature values, the position of the divert valve and the flow of the media for the whole process time. The controller has graphical interface for viewing the recording in real time as well as all past recorded processes. The data is stored on a portable memory card and can be used for process and quality control.
Record Parameters:
- temperature pasteurized milk,
- temperature hot water,
- position of the divert valve,
- pressure difference,
- product flow,
- temperature of the milk at the exit from the process,
- date and time.
Power supply:  400V 3N 50Hz; 27 kW
Measurements: (L) 2200 x (D) 1200 x (H) 1800 mm
