PPTD Sealed Filter-Bag Centrifuge (Botanical Extraction + Dewatering)
Application: Ethanol-based botanical extraction; filtration and dewatering in one unit
Process: Load dry biomass into a zipper filter bag → add solvent → bi-directional agitation for extraction → drain → high-speed spin-drying for solid–liquid separation
Closed Operation: Helps reduce solvent evaporation and odor escape
Control & Drive: Explosion-proof motor, VFD for adjustable speed profiles, PLC + touchscreen HMI for repeatable recipes
Build: Food-grade stainless-steel wetted parts for corrosion resistance and cleaning
Operation Options: Standard manual valve setup; optional electric valve for automatic operation
Capacity Range: Multiple models covering 6–520 lbs per batch (dry plant)
- The whole operation process is controlled by frequency conversion, you can choose manual or automatic operation, the loading and dehydration speed can be set according to different materials for the best, ,it can separate many varieties of mixture if choosing suitable filter medium.
- It can be used according to the requirement, applicable to the airtight, explosion-proof, poisonous, harmful and flammable materials.
- It is widely used in plant extraction, medicine, pharmaceutical intermediates, vitamin, Chinese medicine, amino acids, antibiotics, pesticides, herbicides, etc;
- The part of contacting materials adopts stainless steels, it has a good corrosion resistance, the material can use titanium, PE-RT,2205 duplex stainless steels etc if containing chlorine ion and other special materials.
- Easy maintenance: Simple structure for easy cleaning and upkeep, reducing operating and maintenance costs.
- Food-gradematerials: Every machine uses food-grade materials and durable, hygienic stainless-steel welded construction. This ensures easy cleaning and supports operation in a sanitary washing environment. Compatible with multiple CIP detergents/cleaning agents.

What is the typical cycle time?
About 30 minutes per 40 lbs run depending on biomass preparation, spin profile, and target solvent recovery.
Can I run cryogenic ethanol with this centrifuge?
Yes. The unit is compatible with cryo-range ethanol processes to preserve cannabinoids and terpenes. Pair with insulated lines and an appropriately sized chiller for best results.
Do you offer installation or some operatation help?
The installation and operation of the centrifuge are very simple—don’t worry!If you encounter any issues, we can offer remote guidance via video to help you through the process.
Is the motor explosion-proof?
Yes — the drive system uses an explosion-proof motor. Follow all local codes and ventilation requirements.
DISCLAIMER: Our closed-loop systems are intended for legal purposes only. Operate in a well-ventilated area and in accordance with all local, state, and federal laws. Qualified professionals should install and operate this equipment.

Double-layer stainless-steel
The centrifuge features a double-layer jacket that allows circulation of cooling media for precise temperature control. During cannabis ethanol extraction, low temperatures help minimize impurities, improve extract purity, and reduce solvent evaporation, ensuring a safer and more stable process.

Food-grade materials
Every machine features food-grade 304 stainless steel and durable, hygienic welded construction. This ensures easy cleaning and reliable operation in sanitary wash-down environments. The design withstands temperatures as low as -40°C or below.

easy operation
Built for cannabis ethanol extraction, our centrifuge features an explosion-proof motor with VFD, plus a PLC-controlled touchscreen that keeps every run stable and repeatable. The integrated control system delivers precise speed regulation, fully automated cycles, and real-time data monitoring—all while keeping operators safe in hazardous environments. Designed for repeatable results and full regulatory compliance.
