BEYOND'S falling film evaporators are specially designed to obtain
high quality concentrated juice, whey, pharmaceutical liquids and
other heat sensitive materials. The evaporator operates under
vacuum and low temperature, which is the key factor in maintaining
the organoleptic properties of the processed products. The multiple
effects design allows energy savings thus reducing operating costs.
In falling film evaporators, liquid and vapors flow downwards in
parallel flow. The liquid to be concentrated is preheated to
boiling temperature. An even thin film enters the heating tubes via
a distribution device in the head of the evaporator, flows downward
at boiling temperature, and is partially evaporated. This
gravity-induced downward movement is increasingly augmented by the
co-current vapor flow.
Features:
1. Adjustable and controllable direct contact heat treatment units.
2. Shortest possible residence time, presence of a thin film along
the entire length of the tubes reduces holdup and residence time.
3. Special design of liquid distribution systems to ensure correct
tube coverage. The feed enters at the top of the calandria where a
distributor ensures film formation on the inside surface of each
tube.
4. The vapor flow is co-current to the liquid and the vapor drag
improves the heat transfer. The vapor and the remaining liquid are
separated in a cyclone separator.
5. Efficient design of separators.
6. Multiple effect arrangement provides steam economy.

In the field of beverage, falling film evaporator is widely used to concentrate glucose, starch sugar, maltose, milk, fruit juice, vitamin C and other aqueous solutions. Vacuum continuous low-temperature evaporation saves energy and time, with low loss, which is convenient to maintain the color, taste and nutrition of the product. It can meet the requirements of continuous production.
Falling film evaporator structure
Falling film evaporator is composed of (first effect, second effect
and third effect) separator, evaporator and preheater, condenser
and vacuum pump, feed pump, circulating pump, discharge pump,
condensate pump, pipeline and accessories, equipped with CIP spray
cleaning ball, vacuum gauge, thermometer, pressure gauge, etc.
Characteristics of falling film evaporator
Evaporation capacity: from 500kg / h to 80t / h.
It can also be used together with forced circulation evaporator and
crystallizer to deal with the concentration of high viscosity and
easy scaling materials and product crystallization.
It has the characteristics of high heat conduction efficiency and
low power consumption.
It can widely use waste heat (such as hot air and flue gas of
dryer) and waste heat (condensate, process water and flash steam)
to form waste heat evaporation unit.
Large concentration ratio: falling film evaporation is adopted to
make the liquid with high viscosity easy to flow and evaporate, not
easy to scale, short concentration time, and the concentration
ratio can reach 1:5.
The equipment can realize automatic production and intelligent
system management.
Different technological processes can be designed according to
different characteristics of materials and different requirements
of users.
