Multi-effect countercurrent, downstream and falling film evaporator series equipment are special equipment for evaporation and concentration of corn syrup, fermented sugar juice industry, fruit juice, beverage industry, milk liquor, liquor tank filtrate, pharmaceutical industry, fermentation feed, and high concentration organic or chemical wastewater. It has the advantages of short heating time, suitable for evaporation, concentration and concentration of materials with high viscosity, and can also obtain high-quality deionized water to meet the needs of industrial boiler water. It can also be combined into double-effect, three-effect, four-effect and five-effect evaporation systems. The waste steam at the top of the tube bundle or disc dryer and other low calorific value heat sources (such as condensate steam) can also be used as the heat source of the evaporator to become a waste heat evaporator, which can greatly reduce the consumption of raw steam and achieve a large effect. When there is sufficient supply of waste heat steam, the steam generation can be completely eliminated and significant economic benefits can be achieved.

working principle:
The material is evenly distributed to each evaporator tube through the distributor. The material flows from top to bottom in a spiral film shape under the action of gravity and the secondary steam in the form of self-evaporation. At the same time, the material film exchanges heat with the steam on the outer wall of the tube, so that the water in the material is heated and evaporated. The stable temperature difference and heat transfer area form a stable water evaporation capacity. The secondary steam formed by the evaporated water is used for many times, Maximize the use of heat energy, reduce steam consumption, and form the design principle of multiple evaporation.

Performance characteristics:
The distribution plate of the evaporator is spiral, the material distribution is particularly balanced, and the liquid falls in film form along the inner wall of the tube, which is suitable for sugar concentration
The top cover of the evaporator is flat for easy cleaning and maintenance.
If the production volume does not require large evaporation. The heat exchange area can be changed.
The vacuum system can be selected by the user, either water ring vacuum pump or water jet pump.
Condensate can be recycled.
When the evaporation capacity is 3900kg/h, the steam consumption is 1300kg/h.
Small heat dissipation, especially secondary steam.
Convenient operation and small floor area.
