The pasteurisation unit (HTST pasteuriser) is designed for the thermal treatment of milk and dairy products as well as other food products as soft drinks and. For more than 30 years REDA S.p.A. has been acting in the milk pasteurization process, using and constantly developing the plants of the series HTST (High. This innovation in HTST pasteurization is poised to transform the capabilities of dairy processors, allowing them to offer pasteurized milk that is farm-fresh and.

Turn off the air supply and the main electric switch at the panel. With operator control, changes can be made to the program which might affect CCP’s; the system is not easily sealed.
Milk HTST Pasteurizer
Ice-water connection if required: Fill the hot water tank, start the hot water pump and inspect the tank after min for the level. If required, the unit must be provided with glycol water for cooling and with hot water or industrial steam at 3 bar.
Alarm system with optical and acoustical signals for temperature and pressure differences Security switch-over valve, one-seat version, for alarm cases, leading the product without pasteurization pasreurizer to the receiver tank.
Periodical inspection of individual plate surface and gaskets must be done when the pasteurizer is dismantled for manual cleaning. Once the chilling temperature is reached, the plant will pasteuriezr itself to forward flow.
Pasteuriser HTST – Heat treatment INOXPA
The pasteurizer should be inspected every day for any leakage and for ensuring cleanliness. The package constitutes a tested filter system and a circulation cleaning system.
Auxiliary Equipment Booster Pump It is centrifugal “stuffing” pump which supplies raw milk to the raw regenerator for the balance tank. At the pasteurized product discharge is a vacuum breaker which breaks to atmospheric pressure. This gives rise to a need for specific regulations or computer controlled CCP’s of public health significance: It monitors, controls and records the position of the flow diversion device FDD and supplies power to the FDD during forward flow.
DT Lesson WORKING OF HTST PASTEURIZER
A centrifugal pump with magnetic flow meter and controller may also be used see below. The pump, then controls the flow rate of product through the system and its holding time in the holding tube.
This step requires power. Start the air compressor.
The panel includes a temperature regulator. The plant must be sterilized. It governs the rate of flow through the holding tube. There are two types of FDD:.
To kill bacteria including pathogens. This system does not use a control valve but rather the signal from the magnetic flow meter is transmitted to the AC variable frequency control to vary the speed of the centrifugal pump.
The filter cloth or filter bag must be changed at regular intervals. Any loose or broken gasket must be replaced, using proper adhesive.
Stop the milk and hot water pumps. All recording instruments, thermometers etc.
Control devices with all necessary switches and regulators Electric boiler with hot water circulation pump Two product pumps: In operation, the electrical signal is sent by the magnetic pasteuriizer meter to the flow controller, which determines what the actual flow is compared to the flow rate set by the operator.
Plate heat exchanger module according to the capacity, involving 3 sections like heat recuperator, heater and cooler. DN10, Cooling supply requirements: Hyginox SE centrifugal pump. It ensures pasteurizr nothing downstream is creating suction on the pasteurized side. Place a hose in the balance tank and flush the plant thoroughly with water until the discharge from outlet becomes clear.
If the heat exchanger has a regeneration stage, the treated product is used to preheat the feed material, losing heat in the process, this, reducing the energy required to reach the pasteurising temperature and in reducing the cooling required.
Application of the magnetic flow meter hhtst the dairy industry has centered around its replacing the positive displacement timing pump as the metering device in HTST pasteurizing systems, where with certain products the timing pump rotors reportedly wear out in a relatively short period of time. All air-operated equipment should be supplied paxteurizer clean dry air. No computer program can be written completely error free in large systems; as complexity increases, so too do errors.
