The falling film evaporator has a very efficient control system. The falling film evaporator of beyond adopts the PLC of Siemens as the control master station, realizing the control function of high cost performance. The whole production process realizes the PLC function. It can avoid material loss and production equipment damage caused by human factors.


Detailed display of control system
Liquid level control of material balance tank

The balance tank is equipped with a liquid level gauge, and the pneumatic valve is controlled by PLC, so that the real-time liquid level can be seen on the operation interface, and the high or low level alarm can also be carried out.


Automatic water make-up control of feed balance tank

When the water level in the balance tank is too low, the water make-up gas valve will automatically open to make up soft water, thus avoiding the dry burning of the evaporator.


Control of evaporator feed rate

There is an electromagnetic flowmeter in the evaporator to measure the materials, and the relevant data information will be displayed on the PLC system, so that the operator can always know the entry of materials and control them in real time.


Temperature control

The temperature signal is detected by the temperature sensor, the steam valve is adjusted by the signal transmission, and the sugar content information is measured by the sugar content meter, so as to control the temperature and sugar content well.


Level control 

There is a liquid level transmitter at the bottom of the tank, through which the liquid level signal is transmitted to the PLC system, so as to prevent the situation of high liquid level or idling due to lack of material.


Vacuum control

Measure the vacuum degree of the evaporator through the vacuum pressure transmitter, and adjust the vacuum through the regulating valve to keep the vacuum degree of the whole equipment constant.


Automatic cleaning control

The direction of the cleaning pipeline and the material pipeline shall be the same. Spray balls shall be installed in the separator and separation bin to control the times and time of cleaning through the degree, so as to achieve the goal of automatic cleaning.
