KFJ-200 Vacuum Emusifier

● Description, Appearance and Instruction

1. Model KFJ-200 vacuum emulsifying mixer is a coaxial and triple type mixer, suitable to stable homogenizing and emulsifying, the finished granular is very small. The quality of emulsifying depends on the disperse of the granular on the preparation stage. The smaller the granular is, the weaker the trend of accumulation to the surface becomes, thus the smaller the opportunity for the emulsifying to be broken becomes. Relying on mixing of reversed impeller, under the condition of homogenizing turbine and vacuum status, you can get the high-quality effect of emulsifying and mixing.

Description of Whole Machine

1. Low speed mixing system

1.1 Two reversed low-speed mixing systems are composed of a hanging bracket full of scrapers as well as intermediate impeller.

1.2 The full automatic movable scraper's surface is made of PTFE, only working under the condition with material. It's easy for disassembly and cleaning.

1.3 Dynamic balancing coaxial shaft

1.4 Outer hanging brackets and inner impellers are made of stainless steel SUS316L.

1.5 The timing is controlled by PLC to facilitate the setting of working time. The mixer will not work if the time is not set.

1.6 The speed of the equipped reducer motor can be controlled directly by transducer to0-40 rpm.

1.7 The low-speed mixing system produces two independent countercurrent flows inside the material.

1.7.1 One vertical fluid along the center can force material flow to the bottom of container. Its function is to convey the material to the bottom of homogenizing-turbine rapidly.

1.7.2 Another circle flow forces the material encircle the inner wall of the mixing container to facilitate the material to make heat-exchange during heating or cooling stage, which can prevent the material from being damaged due to overheat or overcooling.

2. High speed homogenizing mixing system  

2.1 High-speed homogenizing-mixing activity is accomplished by one turbine installed on the center bottom of tank.

2.2 Turbine is composed of dentate stator and rotor with impeller.

2.3 Turbine is made of stainless steel SUS304 or SUS316L, rotating parts pass the dynamic balancing coaxial shaft.

2.4 The timing is controlled by PLC to facilitate the setting of working time. The mixer will not work if the time is not set.

2.5 Adjust speed by frequency control: 1150-3500 rpm

This kind of structure i.e. executing on the turbine not from the bottom can assure high cleanness of the process project. The reasons are as follows:

a. The material will not be polluted without the influence of motor flange connection.

b. Turbine is made easy for cleaning, maintenance, assembly and disassembly.

c. The bottom of tank is completely smooth without connection and is easy to clean.

d. Assemble a central valve for discharging.

e. The mixing and homogenizing motors are installed on the top of the tank, which is far from the processing area.

f. Strictly ensure the safety of the operators.

3. Heating/cooling system

3.1   Electricity heating

3.2  The temperature of material in the container may be controlled

through temperature sensor signal from the PLC.

3.3   Temperature control is composed of PLC temperature module and temperature sensor installed at the bottom of the tank. Actual temperature of material may be read correctly.

3.4   Cooling is directly accomplished by the external cold water through the jacket.

4. Vacuum system(-0.09Mpa)

4.1 Liquid ring vacuum pump is equipped with solenoid control valve

at the water entrance.

4.2 Vacuum gauge indicates the vacuum in the container.

The vacuity may be set by using the vacuum gauge with max value and min. value.

4.3 Vacuum safety switch is designed to keep the upper cover from opening

at the state of vacuum.

4.4 Air tightness of upper cover is ensured by the silicon filling material on the flange.

5. Upper cover lifting system

The lifting of upper cover is fulfilled by a series of hydraulic devices. The device is fitted with a safe limit system, which can keep the upper cover stopping at any expected position.

6. Tilting system of container

Tilting system of container used for discharge is accomplished by a series of mechanical devices and stops at any angle.

7. Feeding system

7.1 Directly add the material to the tank after opening the cover.

7.2 Under the vacuum condition, the material will be absorbed into the tank by the suction valve through the strainer. Under the vacuum condition, the additive (powder) will directly enter the turbine through the hoper for excipient and additive mounted on the upper cover or the valve at the center bottom of tank so as to shorten the dispersing time.

8. Discharging system

8.1 Discharge the material from the container.

8.2 Discharge the material by compressed air to positive pressure. (less 0.05Mpa)

8.3 Discharge through cam rotor pump. (Extra purchase)

9. Process system

Observation window is equipped with wind board and lamp with good inner visibility.

10. Safety system

10.1 If the upper cover is not completely aligned with the container without enough tightness, stop using it.

10.4 If the upper cover is not perfect in conformity with the container, the discharging performance stops.

10.3 If the upper cover is not lifted entirely, stop using tilting function.

10.4 When the upper cover is open, stop using the mixing and homogenizing motors and vacuum pump.

10.5 Limit micro switch automatically executes the ON/OFF of the upper cover.

Note: Different parameters can be altered to the request of users to reach optimal performance.
