Centrifuge, also called Centrifugal extractor, used for low-temperature extraction of hemp or other plant cytoplasm, with the function of spin-dry the extraction liquid.
DOVMXtech centrifuge is specially optimized for ethanol extraction of hemp oil or plant essential oil.
These Basket centrifuges have been upgraded for plant oil extraction. All units have been upgrade for cold temps( -60*C) with special seals, coolant jackets and more. The units come with explosion proof motors and anti static belts. Bi-directional...work like big washing machines.
These Basket centrifuges are perfect for extracting precious alcohol from the extracted plant matter.
The units come with explosion proof motors and anti static belts.
Cannabinol soak extraction centrifuge uses special structure for dehydration; During soaking, the solid will move and mix at a low speed in the rotating drum, so that hemp biomass can be fully immersed in the soaking solution, and can be fully reacted and extracted in the rotating drum. Each jacketed centrifuge is equipped with explosion-proof motor. It is mainly applicable to the soak and extraction of hemp Biomass. The soak solution is ethanol, the soak temperature is - 40 ℃ to - 60 ℃, and the machine shell is double-layer, which is mainly used to extract cannabinol; Cannabis soak extraction centrifuge is a closed and intermittently operated filtering equipment with upper discharge.
Put the hemp biomass into the filter bag and put them into the rotary drum, then inject ethanol for soaking. When soaking, rotate forward and reverse at low speed. After extraction, under the action of centrifugal force field, the liquid phase passes through the filter medium and is discharged out of the machine, and the solid phase is trapped in the filter bag, with the water content less than or equal to 5%. After shutdown, open the machine cover and take out the filter bag.

EXTRACTION CYCLE
DOVMXTECH Alcohol Extraction Machine offers 3 Program cycles: 1. Spray wash; 2. Agitation wash; 3. Spin dry cycle.
Operator fills filter bag with milled plant material and places it in the machine.
The Alcohol Extraction Machine is then flooded, and bi-directional agitated for full target compound removal.
After the wash, the plant material undergoes a medium duty spin dry till high speed spin dry to remove the liquid as much as possible.
The alcohol wash is then collected to a tank for further processing.
WORKING STEPS
- System loading: A pre-loaded closed filter bag is placed into the basket and the system is sealed to begin the cycle.
- Program Menu: The 'Spray Wash' or Agitation Wash' program is selected on the program manu where the RPM and cycle times are set to the operators specifications.
- Alcohol Fill: Alcohol is pumped from source tank into the centrifuge via an inlet valve or spray nozzle.
- The Wash cycle: The plant material undergoes either a spray wash or an agitated wash with a set number of bi-directional agitations.
- System Draining: When the wash cycle is complete, the outlet valve is manually opened and the liquid drained. The alcohol wash is pumped to a properly rated storage tank for further processing.
- Spin Dry Cycle: The Spin Dry program is selected on the program and the drying cycle is started. The wet plant solids are spun dry of the remaining alcohol mixture within.
- System Unloading: when the dry cycle is complete, centrifuge is unloaded by taking the filter bag out from the basket
- Repeat Process.

Daily maintenance of centrifuge
1. Before the centrifuge runs, cut off the power supply and release the centrifuge brake first, and then try to turn the drum manually.
2. Check other parts for looseness and abnormality.
3. Turn on the power supply and start in clockwise direction (usually it takes about 40-60 seconds from static state to normal operation).
4. Generally, each equipment must operate for about 3 hours without any abnormality after arriving at the plant.
5. The materials should be placed evenly as far as possible.
6. The operation shall be carried out by specially-assigned person, and the capacity shall not exceed the rated quantity.
7. It is forbidden to overspeed the machine to avoid affecting its service life.
8. After the machine is started, if there is any abnormality, it should be stopped for inspection, and it should be disassembled, washed and repaired.
9. The centrifuge operates at high speed, so it is not allowed to touch the drum with your body to prevent accidents.
10. The mesh number of the filter cloth should be determined according to the size of the solid particles of the separated material, otherwise the separation effect will be affected.
11. In addition, the filter cloth and sealing ring shall be embedded into the sealing groove of the drum during the installation of the filter cloth.
12. In order to ensure the normal operation of the centrifuge, please refuel and maintain the rotating parts every 6 months.
13. At the same time, check the running lubrication of the bearing for wear.
14. Check whether the components in the brake device are worn, and replace them if they are serious, and check whether the bearing cover has oil leakage.
15. After the machine is used, clean it and keep it clean.
16. In addition, operate in strict accordance with equipment requirements and regulations. Non-explosion-proof centrifuges must not be used in flammable and explosive situations.
