HTST PASTEURIZER PDF

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.

Components of the compact unit: Magnetic flow meters shown on the right can be used to measure the flow rate. The milk and the heating circuit are equipped with htsh steel pumps. It ensures that nothing downstream is creating suction on the pasteurized side.

The filter cloth or filter bag must be changed at regular intervals.

However, it will be in diverted flow and never in forward flow. Once the chilling temperature is reached, the plant will pasteuizer itself to forward flow. The process destroys pathogenic microorganisms by heating the product to a moderately high temperature for a brief period. Tube section for sec pasteurization temperature holding time, at min. At the pasteurized product discharge is a vacuum breaker which breaks to atmospheric pressure. Chart recorder, multi-channel, with memory card for data storage.

HTST Pasteuriser

I have read and accept the privacy policy. There are two types of FDD: In operation, the electrical signal is sent by the magnetic flow meter to the flow controller, which determines what the actual flow is compared to the flow pasteurizerr set by the operator.

This step requires power. Application of the magnetic flow meter in 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.

The plant must be sterilized. Switch on the control panel mains. Energy recovery is approx. If the flow rate is exceeded for any reason, the flow diversion device is put into diverted flow. Admit cold water to the hot water tank and run until the plant is cold. This gives rise to a need for specific regulations or computer pqsteurizer CCP’s of public health significance: If, due to any problem, the pasteurising temperature is lower than the required one, an automatically operated flow divert valve sends the product back to the balance tank BTDthus, preventing any microbial contamination of the final product.

The balance, or constant level tank provides a constant supply of milk. Set the temperature controller at pasteurization temperature minimum The probe should sit as close as possible to STLR probe and be located not greater than 18 inches upstream of the flow diversion device. Control devices with all necessary switches and regulators Electric boiler with hot water circulation pump Two product pumps: The indicating thermometer is considered the most accurate temperature measurement.

HTST milk pasteurizer (Flow pasteurizer)

As the last milk leaves the balance tank, tip in the water from the tank. 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. A htsr difference from the normal HTST system with timing pump comes into focus at this point. The pump, pasfeurizer controls the flow rate of product through the system and its holding time in the holding tube.

Stored data can be downloaded to PC for further processing, printing and archiving. It must be used in conjunction with pressure differential controlling device and shall operate only when timing pump is operating, proper pressures are achieved in regenerator, and system is in forward flow. All air-operated equipment should be supplied with clean dry air. Hyginox SE centrifugal pump. It monitors, controls and records the position of the flow diversion device FDD and supplies power to the FDD during forward flow.

It, therefore, helps to maintain a higher pressure on the pasteurized side of the heat exchanger. Request information Pasteuriser Request information. Ensure availability of sufficient water in the storage tank approximately, equal to the capacity of the plant. Fill the hot water tank, start the hot water pump and inspect the tank after min for the level.

The package constitutes a tested filter system and a circulation cleaning system. When milk passes through the magnetic field, it causes a voltage to be induced, and the generated signal is directly proportional to velocity. Turn off the chilled water in the cooling sections. You are currently using guest access Log in.

A centrifugal pump with magnetic flow meter and controller may also be used see below. Periodical inspection of individual plate surface and gaskets must be done when the pasteurizer is dismantled for manual cleaning.
