The industrial centrifuge adopts a closed structure, and the seal is made of PTFE; The explosion-proof motor, frequency changer, PLC, touch screen and other devices can be used to achieve the sealed explosion-proof requirements.
Industrial centrifuge can be used to extract and filter centrifuges for cannabis and other plants. The series of centrifuges extract the active ingredients in plants through a built-in program, which is single-handed, easy to use and large in capacity.
Working Principle
The operator fills the filter bag with ground plant material and places it in the machine. Then, ethanol is added until the plant material is submerged, and the program is set to bidirectional (positive and reverse alternating) rotation to fully extract the active ingredients in the plant. The bottom valve is opened to release the extract, and then the plant material is subjected to high-speed rotary exhaustion of fluid to completely recover the extract.

Installation & Adjustment
1.The machine must be kept in storage before and after installation. Pay attention to the moisture protection of the motor and pay attention to the protection of the electronic control system.
2.Safety must be taken during lifting to prevent the machine from being damaged by collision.
3.The centrifuge installation must be horizontal and the reference surface is the upper plane of the machine base (level ≤ 3mm).
4.There should be sufficient space between the equipment and other equipment installed adjacent to the centrifuge and the centrifuge to prevent the machine from colliding with it and causing damage or noise, and to facilitate inspection and maintenance of the machine.The space required for the use and maintenance of the centrifuge should be considered during the installation position of the centrifuge.There should be a pedestrian passage of not less than 1 meter around the centrifuge main unit. There must be more than 2 meters of assembly and disassembly maintenance space above the centrifuge main unit.
5.Because the centrifuge has slight vibration during high-speed operation, the pipe (feeding pipe, outlet pipe, washing pipe, exhaust pipe, cable pipe, etc.) connected to the centrifuge must be flexibly connected, and the connection must be reliable. Sealed or insulated to ensure no leakage and safe use of electricity. The diameter of the external outlet pipe shall not be less than the diameter of the machine outlet pipe, and shall not have dead bends or blockages. The pipe arrangement shall be lower than the height of the outlet pipe outlet and have a certain height difference so that the liquid discharge is unblocked.

Precautions for Use
1.Select the appropriate filter cloth type to make the filter bag according to the characteristics of the separated materials. And ensure the filter bag and the drum body have a good fit according to the filter bag provided by the manufacturer.
2.The electrical wiring is connected by an electrician according to the electrical control schematic diagram of the PP series centrifuge to wait for the operation and adjustment of the centrifuge.
3.After the centrifuge is installed, turn on the motor power, adjust the tension of the motor’s V-belt, and prepare for the test run.
Warnings
7.1 The cover must be covered and locked before the machine is running!
7.2 Do not open the cover when the machine is running!
7.3 It is strictly forbidden to use rigid connection among the feeding tube, the washing tube and the liquid discharging tube on the main machine of the centrifuge, so as not to affect the vibration damping system of the main machine itself and damage the machine.
Industrial Centrifuge Used
1 Power supply and motor
a. Power supply: three-phase or single-phase 220V/60Hz; see the technical parameters for motor power.
b. The motor must be grounded reliably to ensure safe use of electricity.
c. The connection between the centrifuge and the power source is wired according to the electrical control schematic diagram (Fig. 3). The electrical model and specifications are configured according to the motor power and rated current, and are configured according to the relevant electrical control standards to prevent electrical overload and effective. Implement overload protection.
2 Drag and control
a. The drum of the centrifuge is driven by an explosion-proof AC motor, and the inverter or clutch is activated.
b. The brakes are in the form of variable frequency energy brakes.
3 Industrial centrifuge operation
3.1 Preparation before starting up
a、Clean working place before starting up in order to eliminate obstacles, and check the parts below;
b、Turning the drum by hand shall not cause seizure or seizure;
c.、The bolts of all parts should be tightened without looseness;
d、Check whether the filter bag meets the material deliquoring requirements and must not be damaged;
e、The cover of the cabinet cover should be flexible and reliable;

3.2 Starting up and operation
3.2.1 Frequency conversion start
(1) Turn on the power, open the control cabinet and the operating cabinet power supply. Then the inverter runs according to the preset parameters (starting time, speed section, braking time, speed display, etc.) (parameters can be modified, refer to the inverter manual), and the panel of the operation cabinet is shown in the figure.
(2) Now, the extracted material is loaded into the filter bag, and the zipper is pulled into the centrifuge to check whether the charge is even. The upper part of the display is the display area and the lower part is the operation area.
(3) Close the top cover of the centrifuge and press the crimp. Make sure the outlet valve is closed, open the inlet tube valve, and add alcohol to the material that has not been extracted.
(4) Set up separating parameters, which includes the extraction forward rotation time (generally 60 seconds) extraction forward rotation speed (generally 200RPM), extraction reversal time (generally 60 seconds) extraction reversal speed (generally 200RPM), the number of cycles (generally 5 times), dehydration time (usually take 5 minutes), dehydration speed (take the corresponding model maximum speed), forward and reverse waiting time (usually take 30 seconds).
(5) Press the start button.
(6) Open the outlet valve after the extraction cycle to finish. And after all the extract is discharged (after it has to be drained), press the dehydration start button and the machine starts dehydration.
(7) After the dehydration is completed, release the lock handle after the device stops, open the flip cover of the centrifuge, and manually remove the filter bag. Pay attention to the protection of the filter cloth when unloading, in order not to cause damage to the material and vibration during the next use.
(8) Make sure the filter bag is intact, reload the extracted material, cover the cover and lock the handle to start the second working cycle.
(9) Notes: The speed increase (start) time and speed reduction (braking) time of the inverter are set internally. The users can make appropriate adjustment according to the actual situation, but it must be set by professional personnel. Please refer to the instruction manual of the inverter for the specific setting method.
