| Liquid from the top of the liquid distribution device evenly into the heating tube, under the action of gravity, liquid material along the inner wall of the pipe into the membrane decreased, evaporating, the bottom entering the vapor liquid separator, a concentrated solution by separator bottom discharge, escape from the top by two steam separator. As a result of the two steam flow and material flow, so the liquid material along the inner wall of the pipe downward movement and distribution into a film, play a further role.

- The heating system of steam heating equipment due to uniform, liquid for the liquid film flow evaporation, so it has high heat transfer efficiency of short heating time, main features. If the configuration of heat pumps, more energy saving, low steam consumption, cooling water circulation etc..
- Material along the inner wall of the pipe downward acceleration of pressurized flow evaporation, adapted to high viscosity liquid evaporation.
- Because the material in each tube film type evaporation, liquid heating time is very short, so special about food evaporation is very beneficial, larger preserved food nutritional ingredients.
- Under the action of vacuum evaporation process, not only guarantees materials hygiene requirements, but also ensure the environmental protection requirement, and reduce the evaporation temperature, together with the configuration of heat pumps, part two by steam pressure pump to suction and steam mixing, saving steam, and the steam is sprayed by hot pump the mist into the heating shell, steam rapid diffusion, liquid heating temperature, so the concentration of thermal sensitive materials.
- Device for foaming material evaporation, the liquid in the heating tube film type evaporation, which formed a vapor-liquid separation, while in effect body bottom, most of which feed liquid is pumped out, only a few part of feed liquid and all two steam enters the separator intensifying separation, liquid whole process not form too big shock, to avoid the bubble formation.
- Evaporation and concentration equipment for food, can also have the function of sterilization, the material with a preheating, then into the sterilizer, reaching 94 degrees or higher, maintained for 24 seconds, enter a effect of effect of body temperature, material quickly flash, a transient decline.
- Equipment can be equipped with CIP cleaning system, realize the complete set of equipment cleaning, convenient operation, no dead angle.
- Continuous feeding device.
- Devices can be configured automation systems, to realize feeding quantity automatic control, automatic control of heating temperature, feed concentration automatic control, cleaning and automatic control, also can be equipped with sudden power failure, failure to sensitivity materials protection measures. Other security, alarm, automatic operation control.

Widely applicable to glucose, starch sugar, maltose, sorbitol, oligosaccharides, milk, fruit juice, vitamin C, malt dextrin water concentration of solution. And can be widely used for alcohol, monosodium glutamate, such as fish meal industry waste water treatment.
The device under vacuum and low temperature conditions for continuous operation, has high evaporation capacity, energy saving, low running cost, can maximally keep processed material original color, flavor, and composition. In food, pharmaceutical, food processing, beverages, light industry, environmental protection, chemical industry and many other water or organic solvent solution evaporation concentration have been widely applied.
