The Pladot Mini-Pasteurizer is built to the PMO specs. It pasteurizes milk by heating it to a specific temperature, maintaining it at that temperature for 16-20 seconds, and then cooling it to the proper temperature for producing different kinds of products, such as drinking milk, yogurt, butter, ice cream, and a wide variety of cheeses.
- The Mini-Pasteurizer is specially designed for small and medium-sized producers.
- The system controls temperature and flow using manual or PLC-controlled devices, ensuring a high-quality end product.
The basic configuration of the system is set to flow rates shown below:
- Capacity: 850-1,000 liters/hour (1,700-2,200 lbs./hour)
- Heating: 60 kW (6 elements of 5Kw each)
- Milk pump: 2 HP, 380V/460V, 3 Phz, 50 Hz / 60 Hz
- Water pump: 0.3 HP, 240V, 1 Phz, 50 Hz / 60 Hz
- Air pressure: 6 bars, 10 liters (2.5 gallons)/minute
- Dimensions: 220 cm x 80 cm x 170 cm (88" x 32" x 68")
- Weight: 500 kg (110 lbs.)
- Balance Tank
The balance tank controls the flow to the milk pump, maintaining it at a constant level. It is also used for cleaning the pasteurizer by circulation during the CIP process. The level control system controls the pneumatic feeding valve and the feeding pump.
- Milk Pump
The milk pump sucks the milk from the balance tank and pumps it to the plate heat exchanger: raw regenerator, heater, and pasteurized regenerator. The bypass valve allows the hot temperature in the outlet product.
- Plate Heat Exchanger
The plate heat exchanger heats the milk to the desired pasteurization temperature and cools it after pasteurization. This is accomplished by heat exchange between the two fluids that pass on either side of a stainless steel plate. Most of the heat exchange is between the cold milk inlet, the hot milk outlet, and finally between milk and hot water.
- Holding Tube
The holding tube is a long stainless-steel pipe which holds the milk at the pasteurization temperature for 16-20 seconds, before re-cooling in the regenerator.
- Hot Water System
The hot water system is used for the final pasteurization of the milk. It includes electric heaters, a circulation pump, piping, and a control board. This panel includes all of the electrical components that operate the pumps, heating system, temperature recorder, and temperature controls. The PLC indicates proper function and operating status of the different elements. The diversion valve diverts the unpasteurized milk automatically to the balance tank.
