Hemp Extraction Centrifuge

A hemp extraction centrifuge is a bowl centrifuge designed to extract the hemp biomass from the alcohol. It uses a centrifugal force of over 3,000 Gs to spin out the biomass solids from the ethanol. The separated biomass and ethanol are continuously discharged from separate discharge ports.

The exponential growth of the hemp industry has seen a variety of hemp extraction centrifuges for sale. Basket type (washing machine style) centrifuges are suitable for small-scale producers whose primary consideration is cost. Product losses are not a significant consideration at lower batch volumes.

Industrial hemp extraction centrifuge needs to be durable and heavy-duty to allow continuous processing with minimum labor involvement and production-related losses.  Also, processing equipment downtime is not desirable for industrial-scale hemp extraction processors.

An industrial centrifuge is a heavy-duty separator that is proven over time to be highly reliable and durable across all industries. Additionally, an industrial hemp centrifuge exerts a much higher centrifugal force, which leads to higher production efficiency and minimum product losses.

Industrial-scale Hemp Centrifuge Process

There are multiple ways to extract CBD oil from hemp. Typically it is a 4-step extraction process that is also used in the cannabinoid oil extraction process.

Step 2 is where the hemp biomass (from step 1) is separated from the carrier fluid by a centrifuge or other separation methods. The separated ethanol (or carrier fluid) now has the Cannabinoid Oil dissolved in it.

Step 3 is the polishing process to remove the remaining small biomass particles and waxes, etc.. This is achieved by a high-g, self-cleaning type centrifuge (or filter) to produce clarified carrier fluid.

Step 4 is the final phase wherein this carrier fluid is distilled or evaporated to produce pure Cannabinoid Oil.

Centrifuges, if designed and used effectively, are ideal for the production of CBD Oil continuously to produce a high-quality, consistent product.

Ethanol Extraction Centrifuge

decanter centrifuge is highly efficient as an ethanol extraction centrifuge. Designed for the Hemp CBD Oil industry, our decanter centrifuges come with Class 1 Div 1 or Div 2 Explosion Proof motors with VFD control. Separated hemp biomass can be as low as 10% ethanol meaning high recovery efficiency.

Industrial food-grade centrifuges and decanters are also well suited to extract flavoring oils from herbal plant matter. Mechanical separation avoids the use of filtration, which reduces operating costs and labor.

Ethanol Wax Centrifuge

Self-cleaning, Disc type centrifuges offer the maximum amount of centrifugal force to separate the wax, lipids, and other suspended particles from the ethanol.

Hemp CBD Oil centrifuges reduce the need to filter the fine solids to purify hemp extract. This is essential to reduce post winterization filtration load. 

Dolphin Centrifuge has developed a custom-designed line of Hemp CBD Oil Centrifuges to clarify the ethanol from the previous step of biomass separation using an explosion-proof centrifuge, as shown here.

Warm Ethanol Extraction

Warm ethanol extraction of CBD oil from hemp uses alcohol that has not been super chilled. The ethanol extracts the CBD oil from the hemp biomass and is distilled to obtain CBD oil. This process reduces the energy consumption of the ethanol chillers lowering production costs.

The inherent limitation of decanter centrifuges is the inability to process below the freezing point of water (32 F). This limitation is due to the possibility of environmental moisture condensing and freezing on the rotating centrifuge components.

Warm ethanol extraction removes this limitation and allows the use of decanters for the biomass separation process.
