  • Product Details

Purpose: The equipment is especially suitable for continuous evaporation and concentration of heat sensitive, viscous and foaming materials, such as fermentation liquid, juice juice, glucose, fresh milk, amino acid, xylitol, starch sugar, maltodextrin, corn pulp, etc. It is also suitable for evaporation and concentration of water or organic solvent in medicine, food, chemical industry, light industry and other industries.


Product specification: 0.2-40T/H, can be customized according to capacity.


Working principle: Material from the top of the heater to join first, after liquid distributor evenly into heater within the heat exchange tube, and then in under the action of gravity and vacuum induced force and air flow, homogeneous membrane along the inner wall of the heat exchange tube shed, in the process of flow, the shell side heating medium boiler steam heating evaporation, the steam produced together with the liquid into the separator, The steam is then separated in the separator. The steam rises into the condenser to condense into liquid (single-effect operation), which is collected in the condensing tank. The separated liquid phase is discharged from the bottom of the separator, resulting in concentrate. In multi-effect evaporator, the secondary steam generated by one effect heater can enter the next effect heater as heating medium and get heat energy utilization, so as to achieve the purpose of saving energy consumption.


The complete set of falling film evaporator system mainly includes heater, separator, condenser, condensate tank, condensate pump, vacuum pump, material pump, equipment platform, electronic control system, pipeline system, etc. In order to save steam energy consumption, the equipment has single effect, double effect, triple effect and multiple effect.


1. Heater: used for heating materials, evaporation and concentration.

2. Separator: used for vapor-liquid separation between the secondary steam generated after heating and the concentrated liquid.

3. Condenser: used to condense the secondary steam into liquid for easy recovery and utilization.

4. Condensate tank: used for collecting and buffering condensed water

5. Condensate pump: Used to discharge the liquid in the condensate tank and transport it to the collection pool or discharge.

6. Vacuum pump: used to ensure that the whole system runs in vacuum

7. Material pump: multiple pumps can be used for feeding, transferring, discharging and circulating transmission of processed materials.

8. Equipment platform: mainly used for load-bearing, observation, operation and maintenance of heater, separator, condenser and other components.

9. Electric control system: used for operators to control the operation of pumps and other electrical in the system.

10. Piping system: internal steam piping, material piping, condensed water piping, vacuum piping, etc.

Technical features:


1, the material heating time is short, suitable for the processing of heat-sensitive materials, continuous feeding, discharging, the material in the equipment through one time can reach the concentration requirements, heating time is not more than 3 minutes.

2, compact structure, combined with the production process. The equipment includes the preheating of the material, a continuous completion of preheating and concentration of two processes, saving the supporting preheating equipment, avoiding the opportunity of product pollution, but also reduce the area of equipment.

3, suitable for high concentration, high viscosity material processing.

4, save heating steam. Use gauge pressure 4.5-5kg force.

5, equipment equipped with CIP cleaning pipeline, can realize local cleaning, easy to operate, no dead Angle.

6, large concentration ratio, falling film evaporation, high heat transfer coefficient, so that the viscosity of the material liquid flow evaporation, short concentration time.

7, low steam consumption, can be designed to use jet hot pressure pump, more efficient and energy saving.

8, the material liquid is heated gently, heated for a short time, low evaporation temperature, suitable for the concentration of heat sensitive materials.

9, special design by simple operation can achieve switching effect, to adapt to the production of different products.

10, continuous operation in and out of the material, the material liquid in the equipment through once can reach the required concentration.

11, all power control through the control cabinet to achieve and can be installed according to user requirements automatic control system.

12, concentrator special pump, reliable sealing, stable performance, smooth operation.


Packing: foam film or plastic film, wood support or wood frame fee need to be confirmed.


Control: button control or PLC online control can be used.


Our company provides 1-40 tons/hour double effect falling film evaporator, three effect falling film evaporator continuous vacuum concentrator.
