Ethanol Extraction Centrifuge

Hemp Extraction Centrifuge

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 who’s 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.

In step 1, the hemp is crushed/pulverized and mixed with ethanol (or other suitable liquid media). This mixing allows the media to dissolve the CBD Oil from the hemp biomass – popularly known as ethanol extraction or solvent extraction.

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 high quality, consistent product.

Ethanol Extraction Centrifuge

A 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 for the extraction of flavoring oils from herbal plant matter. Mechanical separation avoids the use of filtration, which reduces operating costs and labor.

Winterization Centrifuge

Winterization of ethanol containing the CBD oil is a process of chilling the ethanol to about -40 F to solidify the waxes, lipids, and other dissolved impurities. The subsequent filtration of the cold ethanol removes these impurities prior to the distillation process.

A ‘self-cleaning’ disc stack centrifuge cannot process fluids before the freezing point of water (32 F). However, the  CBD carrying ethanol cab be processed through our centrifuge at a temperature slightly above 32 F.

A high-speed disc centrifuge offers the maximum amount of centrifugal force to separate the wax, lipids, and other suspended particles from the ethanol. Hemp CBD Oil centrifuges eliminate the need to filter the fine solids to purify hemp extract.

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.
