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.

With operator control, changes can pasteuriezr made to the program which might affect Ntst the system is not easily sealed. The face of the plate bar and the tightening spindle should be kept lightly coated with grease. 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. The milk and the heating circuit are equipped with stainless steel pumps.

The package constitutes a tested filter system and a circulation cleaning system. An integrated after cooling with ice water is optionally available. Components of the compact unit: Ice-water connection if required: 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. The homogenizer may be used as timing pump. This gives rise to a need for specific regulations or computer controlled CCP’s of public health significance:.

It is essentially a short piece of tubing approximately 25 cm long surrounded by a housing, inside of which are located coils that generate a magnetic field. It is a positive pressure pump; if not, then it cannot supplement flow. Close the air vents when the milk comes out from them.

Switch on the control panel mains. This system can be operated at a flow rate greater than residence time less than the legal limit.

The STLR records the temperature of the milk and the time of day.

AISI Pump mechanical seal: Parts in contact with lasteurizer product: There are two types of FDD:. It governs the rate of flow through the holding tube. 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. Control devices with all necessary switches and regulators Electric boiler with hot water circulation pump Two product pumps: The process destroys pathogenic microorganisms by heating the product to a moderately high temperature for a brief period.

A centrifugal pump with magnetic flow meter and controller may also be used see below. Admit cold water to the hot water tank and run until the plant is cold. 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.

Milk HTST Pasteurizer

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. 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.

These systems are used for time and temperature control of HTST systems. The product arrives to a balance tank BTD and is pumped to a plate heat exchanger. The plant must be sterilized.

Basic Component Equipment of HTST Pasteurizer

Stored data can be downloaded to PC for further processing, printing and archiving. The pump, then controls the flow rate of product through the system and its holding time in the holding tube. If the flow rate is exceeded htet any reason, the flow diversion device is put into diverted flow. It must be located greater than 12 inches above the highest point of raw product in system. Pasteurizee 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.

DN10, Cooling supply requirements: Magnetic flow meters shown on the right can be used to measure the flow rate. All recording instruments, thermometers etc. Free circulation from outlet to inlet is required pasteurixer the speed of the homogenizer must be greater than the rate of flow of the timing pump.

HTST Pasteuriser

This FDD can be cleaned in place and is more suited for automation. The indicating thermometer is considered the most accurate temperature measurement.

It pasteuruzer that nothing downstream is creating suction on the pasteurized side. The balance tank provides a means for recirculation of diverted or pasteurized milk. This step requires power. Once the chilling temperature is reached, the plant will set itself to forward flow.
