Zhejiang DaYu Light Industrial Machinery Co., Ltd. |
Our single-effect or multi-effect falling film evaporator is ideal for continuous evaporation and concentration at low temperature in such industries as milk, glucose, starch, xylose, pharmaceutical, chemical, bioengineering, environmental engineering, waste liquor recovery, and some others.
This product is prominently characterized by highly efficient heat transfer, and short heat-up time of material, among others. Therefore, it is especially suitable for heat-sensitive materials, viscous materials, foam materials, and more.
System Components
The falling film evaporator consists of the evaporator, separator,
condenser, steam ejector, sterilizer, insulating tube, vacuum
system, the fluid transfer pump, condensed water drainage pump,
operating platform, the electrical equipment and instrument control
cabinet, as well as valves, pipelines, and some others.
Prominent Characteristics
1. The steam heating is uniform, and the liquid material takes
advantage of film evaporation. Consequently, our falling film
evaporator remarkably features high heat-transfer efficiency, short
heat-up time, and some others. If equipped with a steam ejector, it
will offer such advantages as energy saving, low steam consumption,
and the low volume for circulating cooling water, among others.
2. The material is evaporated at high speed and high pressure,
while it flows down along the inner wall of the pipe. Our product
is suitable for the evaporation and concentration of the
large-viscosity liquid material.
3. In each pipe, the material is evaporated in the form of thin
film. Additionally, the heat-up time of liquid material is rather
short. Hence, the evaporation and concentration of food can be
significantly facilitated, and most of the nutritious ingredients
can be preserved.
4. The evaporation process in vacuum environments can not only
guarantee the environmental requirements and the hygiene
requirements of the material, but also enormously lower the
evaporation temperature.
Through the steam ejector, a part of secondary steam will be utilized again for being mixed with live steam. This can save the consumption of live steam. Simultaneously, the steam will enter the heated housing through the steam ejector in the form of spray mist. The steam will be diffused rapidly, and the liquid material is gently heated. Thus, our product is proper for the concentration of heat-sensitive materials.
5. Moreover, this falling film evaporator is applicable for
evaporating and concentrating the foam materials. The film
evaporation inside pipes allows the liquid material to achieve
vapor-liquid separation. Meanwhile, most of the liquid materials
will be pumped from the bottom of our product. Only a small portion
of liquid material accompanied with all secondary steam will be
sent to the separator for enhanced separation. The whole process
can avoid the formation of foam.
6. In food industry, this falling film evaporator offers such
functions as evaporation, concentration, and sterilization. The
material must be preheated prior to entering the sterilizer. After
being heated to over 94 degrees Celsius for approximately 24
seconds, the material will enter the single-effect machine. Flash
evaporation of the material will occur, and the temperature will be
decreased instantly.
7. Our machine can be fitted with CIP system to realize cleaning in
place. This full set of equipment features convenient operation and
no dead corner.
8. This product is able to get materials in and out continuously.
9. The falling film evaporator can be configured with an automated
system to automatically control the feed quantity, heating
temperature, the discharging concentration, and the cleaning
process. Furthermore, this product can be equipped with the
sensitive-material protection system. It can also achieve the
automatic operation and control of the security alarm and other
systems.
