2、 Slurry evaporatorEquipment principle:
The falling film evaporator belongs to the natural circulation liquid film concentration equipment, with high heat transfer rate and short heating time, suitable for the production of fruit juice and dairy food.Its structure is that the liquid is added from the top of the heater body, and the liquid flows downwards in the form of a liquid film along the inner wall of the pipe under the action of gravity. Due to the downward acceleration, the pressure overcome is smaller than that of the rising film type, and the boiling point rise is also smaller. The temperature difference between the heating steam and the liquid is large,So the heat transfer effect is better. The vapor and liquid enter the evaporation and separation chamber for separation. The secondary vapor is discharged from the top of the separation chamber, while the concentrated liquid is extracted from the bottom.
In order to evenly distribute the liquid material in each heating tube and flow down along the inner wall of the tube, a falling film distributor and distribution plate are installed at the top or inside the tube. It is a porous plate with holes staggered between the heater tubes. The falling film distributor plays a significant role in providing its heat transfer effect.
After evaporation, the liquid flowing down from the falling film feed reaches the required concentration. So, the pipe must have sufficient length to ensure heat transfer efficiency. Because the heating time of the feed liquid is short, it is conducive to the protection of food nutrients. Secondly, when it evaporates, it is carried out in the form of a film, which can avoid the formation of foam and is easier to clean.

3、 Performance characteristics:

oneSteam heating is uniform and has the characteristics of high heat transfer efficiency and short heating time;

twoWaste heat can be used as a heat source to reduce the amount of steam used;

threeThe material is evenly distributed in each heating tube of the evaporator through the distribution device. Under the influence of gravity, vacuum induction, and airflow, the material forms a film and flows from top to bottom. During the movement, it exchanges heat with the heating steam on the outer wall of the heating tube and evaporates;

fourThe evaporation process takes place in a vacuum environment, with a relatively low evaporation temperature, making the evaporator less prone to scaling;

fiveIt is suitable for evaporation and concentration of foaming materials. Since the feed liquid evaporates in a film form in the heating tube, vapor liquid separation is formed. At the same time, at the bottom of the effector, most of the feed liquid is pumped away. Only a small part of the feed liquid and all the secondary steam enter the separator to strengthen separation. The whole process of the feed liquid does not form too much impact, avoiding the formation of foam;

sixFor the evaporation and concentration of fruit juice or dairy products, the equipment can also have sterilization function. The material is preheated first and then enters the sterilizer, which can achieve90-125Degree, maintain30-60In about seconds, the material enters the effect body and rapidly flashes, causing the temperature to drop instantly.

sevenEquipment can be equipped withCIPThe cleaning system achieves on-site cleaning, and the entire equipment is easy to operate with no dead corners.

eightCan be equipped with a steam jet pump to reduce steam consumption and save operating costs.

nineContinuous feeding and discharging of equipment.

tenThe equipment can be configured with an automatic control system, which has complete configuration, operation, monitoring, and control functions. The system includes communication interfaces, display alarms, print reports, control, and other parts to achieve automatic control of feed volume, heating temperature, discharge concentration, and cleaning.
