Performance advantages of spiral plate heat exchangers in instant noodle production

Since instant noodles use palm oil, the spiral plate has a uniform single channel with a high flow rate and a vortex state, so dirt is not easy to accumulate. If foreign matter settles somewhere, the channel will become narrower due to the fluid. If the flow rate remains unchanged, the flow rate will increase, thereby scouring the dirt and achieving self-cleaning effect. According to the feedback from the instant noodle factory, they regularly maintain the equipment. Under normal circumstances, there is no need to clean it. Even during the annual maintenance period, solvent cleaning fluid is used for cleaning. It is simple and easy to operate. The spiral plate will not be blocked and will not be blocked. Long lasting use.

Since the structure of the product is double helix, when properly installed and used, the palm oil that needs to be heat exchanged during the production of instant noodles will reach turbulent flow at a lower Reynolds coefficient, so the heat transfer coefficient is much higher than that of the fluid in the straight pipe. , achieving efficient heat exchange. In previous studies on the heat transfer coefficient, that is, K, the unit is W/(㎡*℃), the Shanghai Research Department has conducted comparative tests. The K value of the Spiral Plate Heat Exchanger is 40 times greater than the K value of the Shell And Tube Heat Exchanger. -70%; in the statistics of the instant noodle production line of Guangzhou People's Machinery Factory many years ago, a 60-square-meter Spiral plate heat exchanger was also used, and the efficiency reached the practical effect of the original 100-square-meter spiral Plate Heat Exchanger, effectively improving the Steam utilization, reducing energy costs.
