Heat exchanger & preheater

In beverage production and dairy processing, liquids are heated to a specified temperature through heat exchange and then rapidly cooled to kill pathogens and extend shelf life. Multiple processes such as heating and cooling malt extract ensure that beer reaches the appropriate temperature and yeast cultivation is carried out. Whether it is a cooler or a preheater, it is necessary to monitor the temperature in the cooling and preheating pipes and the pressure in the food pipeline.

Application Challenge:

1. Frequent temperature fluctuations in preheaters and heat exchangers, especially during rapid heating and cooling processes, may lead to unstable transmitter readings, affecting accuracy and control.

2. In acidic fruit juices, dairy products, or fermentation processes, transmitters come into contact with corrosive media, which can affect equipment lifespan and measurement accuracy.

3. In the heat exchanger, food residues, dairy protein, or other substances can easily form contaminants or scales on the sensor surface, leading to inaccurate measurements and even equipment malfunctions.

4. Food processing workshops typically have complex electrical and mechanical equipment that may generate strong electromagnetic interference, affecting transmission and leading to unstable measurements.

Solution advantages:

1. Each factory transmitter can use temperature compensation technology to ensure the stability of measurement results at different temperatures.

2. The sanitary pressure transmitter uses food grade stainless steel 316L material, whether it is the shell, process connection, or liquid receiving part, to cope with corrosion from different media.

3. The sanitary pressure transmitter has obtained 3A and EHEDG certification, with a simple design, no dirt or grime accumulation, easy cleaning, and a structure without dead corners.

4. Single crystal silicon sensing technology has strong anti-interference ability, and can choose digital signal transmission with stronger anti-interference ability, such as MODBUS, HART, etc.
