The balance, or constant level tank provides a constant supply of milk. Paper o video recorder. 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 paseurizer.
Chart recorder, multi-channel, with memory card for data storage. This step requires power. Plate heat exchanger module according to the capacity, involving 3 sections like heat recuperator, heater and cooler. Hyginox SE centrifugal pump. Plate pasteurizer with cooling of the heated milk by water in counter flow principle ice water after cooling required. Ensure availability of sufficient water in the storage tank approximately, equal to the capacity of the plant. Control devices with all necessary switches and regulators Electric boiler with hot water circulation pump Two product pumps: It, therefore, helps to maintain a higher pressure on the pasteurized side of the heat exchanger.
AISI Other components and control panel: There are two types of FDD: 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.
Quiz 24 Lesson Fill the hot water tank, start the hot water pump and inspect the tank after min for the level. Place a hose in the balance tank and flush the plant thoroughly with water until the discharge from outlet becomes clear.
Close the air vents when the milk comes out from them. Free circulation from outlet to inlet is required and the speed of the homogenizer must htxt greater than the rate of flow of the timing pump.
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. Ice-water connection if required: The pasteurizer should be inspected every day for any leakage and for ensuring cleanliness. These systems are used for time and temperature control of HTST systems. The heat exchanger plates and frame are made of stainless steel. Start flow of the milk to the float controlled balance tank by starting milk pump.
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. Paateurizer monitors, controls and records the position of the flow diversion device FDD and supplies power to the FDD during forward flow.
ASTM D PDF 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. A centrifugal pump with magnetic flow meter and controller may also be used see below. Its efficiency may be calculated as follows: Indicating thermometer The indicating thermometer is considered the most accurate temperature measurement.
The panel includes a temperature regulator. There are two types of FDD:. Start the air compressor. 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.

However, with the desire to see more of the world I said goodbye to the corporate life and started a 6-month solo travelling adventure. A key topic for discussion is the future role iccn new technologies in milk production. My wife Jaime is originally from Canada, so our daughter is first generation Australian but will erport doubt have a mixed accent, for a few years at least. I grew up in Melbourne and trained as a Microbiologist. A tour of Australia with the school pipe band and rugby team was my first visit Dair.
