Descrição

一、Overview of plate heat exchanger

1. Plate heat exchanger is an ideal equipment for indirect heat exchange and cooling by two kinds of fluids with different temperatures through the plate surface. It has the characteristics of high heat exchange efficiency, high heat recovery rate, small heat loss, small floor area, flexible combination and assembly, simple operation, convenient installation and disassembly, long service life, low investment and safe use.

2. Plate heat exchanger is used in food and beverage processing ：

(1) All kinds of dairy products: fresh milk, milk powder, milk beverage, yogurt,etc;

(2) Plant protein beverage: peanut milk, milk tea, soybean milk, soybean milk

beverage, etc;

(3) Juice drinks: fresh fruit juice, fruit tea, etc;

(4) Cool tea drinks: tea drinks, reed root drinks, fruit and vegetable drinks, etc;

(5) Condiments: soy sauce, rice vinegar, tomato juice, sweet and spicy sauce,etc;

(6) Brewing products: beer, rice wine, rice wine, wine, etc.

3. Application in other industrial liquid treatment:

Pharmaceutical, printing and dyeing, heating and ventilation, chemical industry, power station, bath heating, petroleum, metallurgy Domestic hot water, ships, machinery, papermaking, textile, geothermal utilization, environmental protection, refrigeration.

4. Compared with other heat exchangers:

Under the same pressure loss, the heat transfer coefficient of plate heat exchanger is 3-5 times higher than that of tube heat exchanger, the floor area of plate heat exchanger is only one third of that of tubular heat exchanger, and the heat recovery rate can be as high as 90%

二、 Structure of plate heat exchanger

The structural components of plate heat exchanger are double support frame type: mainly plate, heat exchanger rubber, fixed pressing plate, movable pressing plate, upper / lower guide rod, strut, clamping screw assembly, rolling parts, connecting pipe, etc.

三、Plate of plate heat exchanger

1. How many plates are needed in a plate heat exchanger depends on its

type and square area. The gap between adjacent plates forms the channel of

fluid.

The plate is made of SUS304 stainless steel or SUS316L stainless steel

or special plate after cutting and pressing into various corrugated shapes,

generally including wavy and herringbone plates.

These waves have the following three functions:

（1）Increase the effective heat transfer area；

（2）After the plates are assembled, the corrugated plates contact with each other to form

numerous contacts, which enhances the

The steel and hardness of the plate make it able to bear the large pressure difference

between the two channels.

（3）It makes the medium easy to be turbulent in the flow channel and slows

down the formation speed of dirt.
