Small Milk pasteurizer Machine Milky FJ 30 (230V)

Product Information

A constant pasteurization temperature is maintained by a temperature controller acting on the steam regulating valve (2) in Figure 7.2. Any tendency for the product temperature to drop is immediately detected by a sensor in the product line before the holding tube. The sensor then changes the signal to the controller, which opens the steam-regulating valve to supply more steam to the water. This increases the temperature of the circulating water and stops the temperature drop in the product. Holding Standardization is necessary to ensure that all the customers are catered for. Again, it is during the process of standardization that you get to separate the butterfat that is used for making cream and other fat-based products such as butter and ghee. When changes in the composition, processing and use of the product are proposed, the necessary changes to the scheduled heat treatment should be established and a qualified person should evaluate the efficiency of Actuation is essentially as follows: a pneumatic signal from a controller is supplied to a proportioning device, a positioner, at the top of the valve. The positioner ensures that the position of the plug, in relation to the seat, always is proportional to the regulating signal. When the signal corresponds to the pre-set value, the positioner balances the pressures on either side of the piston so that the position of the plug remains constant. In this balanced condition the pressure drop over the valve is exactly what is required, and the measured value registered by the transmitter coincides with the pre-set value.

The flow diversion valve is located between the holding cell and the booster pump. If the temperature drops, the valve diverts the flow. The booster pump is not stopped, but other valves around the heat exchanger will automatically be positioned so that the milk in the regenerative and cooling sections will be circulated to maintain the right pressure in the plant. This also preserves a proper temperature balance. When the heating conditions are acceptable, the process can be resumed without intermediate cleaning. The process is intended to destroy or deactivate microorganisms and enzymes that contribute to food spoilage or risk of disease, including vegetative bacteria, but most bacterial spores survive the process. [1] [2] Care must be taken to avoid any risk of contamination of the pasteurized product by unpasteurized product or cooling medium. If any leakage should occur in the pasteurizer, it must be in the direction from pasteurized product to unpasteurized product or cooling medium. Most transmitters, however, operate indirectly. They measure the changes in a physical quantity, which has a constant relation to the process parameters to be controlled. This type of transmitter was shown previously in connection with the transport of liquid through the line, where a required flow rate is maintained by controlling the pressure of the product at the pump outlet. On the other hand, in turbulent flow the particles have an irregular motion and intermix intensively with each other.

Thermization: Heat the milk to between 57°C to 68°C and hold for 15 minutes. Thermization targets pathogenic bacteria while leaving the good bacteria in the product. The low temperatures do not alter the structure and taste of the milk. An alternate view on the alleged safety of pasteurized vs. natural milk from Johns Hopkins University: Realmilk.com, Webmaster (12 August 2015). "The Johns Hopkins Raw Milk Study – A Campaign for Real Milk". A Campaign for Real Milk. After regenerative cooling of pasteurized milk, it moves to the cooling section of the PHE where chilled water/PHE coolant lowers the temperature of pasteurized milk to 4°C.

Flash pasteurized milk will keep for between 16 and 21 days. For commercial reasons, some manufacturers intentionally reduce the number of days to push the products out of the shelves. The demand for service media (steam, water and ice water) is also calculated, as this substantially influences the choice of valves for steam regulation and ice water feed. If the product pressure drops, the transmitter reduces its signal to the regulator. As the measured value now no longer coincides with the pre-set value, the regulator reacts by increasing its signal to the valve actuator. The positioner then increases the pressure on the upper side of the piston, moving the plug towards the seat. The resulting increase in the valve flow resistance increases the product pressure and the reverse cycle of operations is initiated, retarding the downward movement of the piston. The milk is replaced by water and the pasteurizer shuts down when circulation has continued for a pre-determined time. Feed pumpa b Haug, Anna; Høstmark, Arne T; Harstad, Odd M (25 September 2007).

The regulator in Figure 7.15 is the brain of the temperature control system and the controller is available in many different forms. According to a previous definition, a regulator is a device that continuously compares the measured value with a reference or pre-set (set point) value. Any differential causes the regulator to transmit a corrective signal to the regulating unit, which then adjusts its setting accordingly. The corrective process continues until the measured value and the set point value coincide again. To begin the process, you need to clean the work area, wash your hands and sterilize the jars in which you’re going to keep the milk. You can sterilize containers by boiling them for a couple of minutes. For a flow rate of 20 000 litres per hour, the product velocity in a 76 mm (3") pipe will be 1.25 m/s. The velocity will be 2.75 m/s if a 51 mm (2") pipe is selected. A centrifugal clarifier (not the one used for standardization) is used to remove all soil and sediments from milk.
