Falling Film Concentrator of Evaporation Equipment

Falling Film Concentrator of Evaporation Equipment

Our falling film concentrator of evaporation equipment has three types for your choices, including the single effect falling film concentrator of evaporation equipment, the double effect falling film concentrator of evaporation equipment, and the three effect falling film concentrator of evaporation equipment.

Single Effect Falling Film Concentrator of Evaporation Equipment
The single effect falling film concentrator of evaporation equipment is mainly used for concentration of fluid with a small amount of suspended matters or thermal sensitive materials contained water or organic solvent. It is particularly suitable for cryoconcentration of plant extracts, preconcentration of juice and milk, dealcoholization of beers, and concentration of organic products.

Working Principles
The liquid materials will first flow into our single effect falling film concentrator of evaporation equipment through the upper parts of tube nest. Then it flows into each tube through sparger and forms films on the surface of inner wall of tubes. After heated, the boiling liquid will flow downwards in high speed, and enter gas-liquid separators for concentration.

Our single effect falling film concentrator of evaporation equipment has high heat transfer coefficient, short residence time of liquid materials, and low evaporating temperature.

Double Effect Falling Film Concentrator of Evaporation Equipment
The double effect falling film concentrator of evaporation equipment is suitable to concentrate thermal sensitive materials with low viscosity. It is widely used for waste water treatment, concentration of juice, drinks, milk and liquid materials, and extraction and separation of organic matters.

Working Principles
The double effect falling film concentrator of evaporation equipment has similar working principles with the single effect falling film concentrator of evaporation equipment. However, the difference is the fluid in double effect falling film concentrator of evaporation equipment will be heated twice, and the secondary stream will be used again.

The liquid material is firstly heated in forewarmer. When it is going to boil, it will flow into single effective evaporator to heat continuously. After boiled, the water will flow downwards in high speed and enter into gas-liquid separator.

The secondary steam produced in process of first evaporation will be used as heat source of double effect evaporator. The separated liquid materials will be heated in double effect evaporator again. The secondary steam produced in process of second evaporation will enter condenser for cooling. After that, the concentrated liquid will flow out from the pump.

Three Effect Falling Film Concentrator of Evaporation Equipment
The three effect falling film concentrator of evaporation equipment is particularly designed for concentration of a large of quantity of liquid materials. It is extensively applicable for waste water treatment, or concentration of dairy products, fruit and vegetable, syrup, organic acid, and starch products.

Working Principles
The multiple-effect evaporation system is composed of several single effect evaporators. The operating pressure of third effective evaporator is lower than that of second effective evaporator. The operating pressure of first effective evaporator is the highest.

The steam will only be delivered to first effective evaporator. The secondary steam produced in process of first effective evaporator will be used as heat source of double effect evaporator. The third effect effective evaporator is running under vacuum, and the secondary steam will be cooled in it by cooling medium.

The consumption of steam and cooling water will be obviously reduced as a result that the secondary steam is used for several times.

Features
Compared with other evaporators, the falling film concentrator of evaporation equipment has properties of high heat transfer coefficient, low cost and low power consumption. It is particularly suitable for the concentration of liquid materials with little suspended matters, large evaporation capacity, and big concentration factor.
