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.

When the last portion of water leaves the balance tank, turn the 3-way valve at the finished milk outlet so that the flow is diverted to the floor. Vacuum Breaker At the pasteurized product discharge is a vacuum breaker which breaks to atmospheric pressure.

Start flow of the milk to the float controlled balance tank by starting milk pump. The face of the plate bar and the tightening spindle should be kept lightly coated with grease. I have read and accept the privacy policy. Ice-water connection if required: It, therefore, helps to maintain a higher pressure on the pasteurized side of the heat exchanger. The timing pump draws product through the raw regenerator and pushes milk under pressure through pasteurized regenerator.

Tube section for sec pasteurization temperature holding time, at min.

It is centrifugal “stuffing” pump which supplies raw milk to the raw regenerator for the balance tank. 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. DN10, Cooling supply requirements: A centrifugal pump with magnetic flow meter and controller may also be used see below.

No computer program can be written completely error free in large systems; as complexity increases, so too do errors. The filter cloth or filter bag must be changed at regular intervals. Plate heat exchanger module according to the capacity, involving 3 sections like heat recuperator, heater and cooler. Magnetic flow meters shown on the right can be used to measure the flow rate. Next, the product passes through the holding tube that ensures the correct pasteurisation by holding the product at the required temperature for the specified period of time.

It monitors, controls and records the position of the flow diversion device FDD and supplies power to the FDD during forward flow. The balance, or constant level tank provides a constant supply of milk.

The heat exchanger plates and frame are made of stainless steel. Its efficiency may be calculated as follows: To kill bacteria including pathogens. As the last milk leaves the balance tank, tip in the water from the tank. Timing pump The timing pump draws product through the raw regenerator and pushes milk under pressure through pasteurized regenerator. Remove undesirable odours and flavours 4. Heating and cooling energy can be saved by using a regenerator which utilizes the heat content of the pasteurized milk to warm the incoming cold milk.

It also must be interwired so it only operates when FDD is fully forward or fully diverted, and must be “fail-safe”. Periodical inspection of individual plate surface and gaskets must be done when the pasteurizer is dismantled for manual cleaning. This step requires power.

Fill the hot water tank, start the hot water pump and inspect the tank after min for the level. 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.

Auxiliary Equipment Booster Pump It is centrifugal “stuffing” pump which supplies raw milk to the raw regenerator for the balance tank. Start the air compressor. The pasteurizer should be inspected every day for any leakage and for ensuring cleanliness.

This FDD can pasteurizfr cleaned in place and is more suited for automation. The overflow level must always be below the level of lowest milk passage in regenerator.

Basic Component Equipment of HTST Pasteurizer

Plate pasteurizer with cooling of the heated milk by water in counter flow principle ice water after cooling required. When milk passes through the magnetic field, it causes a voltage to be induced, and the generated signal is directly proportional to velocity. Another magnetic flow meter based system with an AC variable frequency motor control drive on a centrifugal pump is also possible in lieu of a positive displacement metering pump on a HTST pasteurizer.

Chart recorder, multi-channel, with memory card for data storage. Energy recovery is approx. Place a hose in the balance tank and flush the plant thoroughly with water until the discharge from outlet becomes clear.

Plate pasteurizer with cooling of the heated milk by cold milk in counter flow principle energy saving option. Since the magnetic flow meter continuously senses flow rate, it will signal the electronic controller if the actual flow exceeds the set flow rate for any reason.

At the pasteurized product discharge is a vacuum breaker which breaks to atmospheric pressure. The process destroys pathogenic microorganisms by heating the product to a moderately high temperature for a brief period.

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 back to the receiver tank.

However, it will be in diverted flow and never in forward flow. It governs the rate of flow through the holding tube. The pasteurisation unit includes all the necessary equipment for automatic pasteurisation of milk, as well as an automatic control system and an integrated temperature recorder.
