In recent years, the instant noodle industry is also the end customer of the Spiral Plate Heat Exchanger. Because the instant noodles use palm oil, there is a uniform single channel in the Spiral Plate, with a high flow rate and eddy current state, therefore, dirt is not easy to accumulate. If there is foreign matter precipitating somewhere, the passage will be narrowed immediately. As the flow rate of the fluid itself remains unchanged, the flow rate will increase, thus scouring the dirt there, achieve self-cleaning.
