0.4mm 0.5mm Flat Plate Heat Exchanger Milk Pasteurization

High Quality Sanitary Stainless Steel Plate Heat Exchanger For Milk Pasteurization

Description

Plate heat exchanger is a new type of high efficiency heat exchanger which is composed of a series of corrugated metal sheets. Thin rectangular channels are formed between various plates through which heat is exchanged. Plate heat exchanger is an ideal equipment for liquid-liquid and liquid-vapor heat exchange.

Specifications

Feature

The heat transfer coefficient of the plate heat exchanger is high because the different corrugated plates are inverted to each other, forming a complex flow channel, so that the fluid flows in a rotating three-dimensional flow in the flow channel between the corrugated plates, and can be used at a lower Reynolds number (generally Re=50~200) Turbulent flow is generated at the bottom, so the heat transfer coefficient is high, which is generally considered to be 3 to 5 times that of the shell-and-tube type.

The plate heat exchanger has a large logarithmic average temperature difference and a small end temperature difference. In a shell-and-tube heat exchanger, the two fluids flow in the tube side and the shell side respectively. Generally, the flow is cross-flow, and the logarithmic average temperature difference correction coefficient is small. Most of the plate heat exchangers are co-current or counter-current, and the correction coefficient is usually around 0.95. In addition, the flow of cold and hot fluids in the plate heat exchanger is parallel to the heat exchange surface and has no side flow.
