Introduction

Plate And Frame Heat Exchanger has been commonly used in many industries. In Europe, the United States, South Africa and India, many sugar applique the Plate Heat Exchanger in the clear juice heating, percolation method of thin juice heating, syrup molasses into the tank before the heating, as well as the final cooling of molasses (into the waste honey tank before), the effect is good, some sugar mills and trial in the mixed juice heating. Some examples of good applications are listed below.

Heat Exchanger Unit for clear juice heating

A sugar plant in South Africa, with 44 pieces of plate, each heating area of 0.79m2. 130t / h of clear juice flow, from 92 ℃ to 104 ℃ heating, the use of waste steam saturation temperature of 111 ℃, the heat transfer coefficient of 3400W/m2.K, clear juice through the heat exchanger pressure drop of 76kPa; the use of steam valve is not fully open, that is, the actual use of the temperature difference is also smaller, the heat transfer coefficient is also higher.

Clear juice heater open after five weeks of continuous operation, there are some sludge deposits inside, the plate surface with a black film, it is easy to wash away with water. South Germany sugar plant, beet juice volume of 600t / h, clear juice into the evaporation tank before the use of four plate heat exchanger in four stages of heating, respectively, the use of 1 to 4 effect of evaporation tank juice vapor as a heat source, each level of heating to reach the temperature of only 3 ℃ lower than the juice vapor temperature, and finally reached 127 ℃.
