Single, double effect, rising or falling film thin film evaporation device

1、 Main purpose
Suitable for the concentration of thermosensitive dilute liquids in industries such as pharmaceuticals, food, light industry, and chemical engineering.
2、 Device features
This device has the characteristics of high efficiency, energy saving, small size, low cost, continuous production, and convenient cleaning. The evaporator adopts a rising film or falling film type, and the liquid stays in the heating tube for only a few seconds. The liquid storage capacity in the tube is small, which can avoid the thermal decomposition of the liquid. Therefore, this device is an ideal equipment for the evaporation of thermosensitive dilute liquid.
The parts and equipment that come into contact with the liquid in this device are made of stainless steel to prevent contamination of the liquid.
This device is divided into two forms: single effect evaporation and double effect evaporation. In single effect evaporation (see Figure 6), secondary steam is used for preheating the feed, thereby improving thermal efficiency. In double effect evaporation (see Figure 7), secondary steam is used for heating evaporation, greatly saving steam. The steam consumption of double effect evaporation is 51% lower than that of single effect evaporation.
The top of the evaporator is equipped with a quick opening cover plate for easy cleaning of the heating tube. There are light holes and mirrors on both sides of the top for easy observation during operation.
3、 Production capacity
When the viscosity of the liquid is below 50CP, the 500 type single effect evaporation device -500kg water/h
500 type double effect evaporation device -1000 kg water/h
4、 Device composition
This device, whether single effect or double effect, has the same specifications and sizes for its evaporator and separator. Other auxiliary equipment such as measuring tanks and concentrated liquid storage tanks are provided by the user, and our company can also process and supply them according to the user's requirements.
