Cannabidiol (CBD) is a compound that has been used in a variety of medical applications including pain relief, relieving anxiety, and many other ailments. Since CBD industry is growing rapidly, the need to process larger quantities of CBD Oil. A filter press is a low-cost, effective solution to help filter CBD Oil out of a slurry of hemp and cannabis.
There are many methods to extract cannabidiol or hemp oil. Ethanol Extraction is one common method that utilizes a maceration process where ground-up hemp or cannabis is mixed with a solvent such as ethanol. The solvent strips out the CBD Oil of the plant fibers, and then the maceration is run through a filter press as a slurry. The solvent is then distilled, resulting in crude cannabidiol oil. With ethanol extraction, the filter press can be clean and used to help Remove Chlorophyll by using activated carbon. This oil can then be further distilled and purified.
CO2 Extraction is another popular way to extract CBD Oil out of cannabis. During the winterization & filtration stage, a filter press can be used to Remove Lipids and Waxes. Usually, this step is done with a Buchner Funnel in the lab, but when your production grows, a filter press will act like a Large Scale Buchner Funnel or an Industrial Buchner Funnel. A Met-Chem Filter Press is the ideal piece of equipment to remove plant waxes and fatty lipids.
It is common for CBD Oil Extraction systems to come with a Buchner Funnel, however these Funnels are typically not able to handle the amount of solids used in a standard CBD or Hemp Oil Extraction process. Because of this, it is common for these filters to clog up very quickly and not allow for the complete filtration of a batch. This can cause many issues, mainly related to the low temperature needed to run the extraction process. The down time for cleaning out the Buchner Funnel can cause issues with the final quality of the CBD or Hemp Oil.
A Met-Chem Filter Press has the advantages of a larger volume of holding capacity for holding the captured solids. This allows the Extraction System to run a complete batch without having to stop and clean out the Buchner Funnel. Due to the high-pressure flowrate of a filter press, we can also use tighter Micron Rating Filters, thus not only improving the CBD or Hemp Oil Extraction Process, but improving the quality of the final product. Another benefit of the higher volume holding capacity, the higher overall feed rate, and pressure is that the filter press will have dryer solids so more of the oil will be removed and not left over in the captured solids.
A filter press used for Ethanol extraction can quickly and efficiently separate biomass from the crude extract. A maceration of ground-up hemp or cannabis is mixed with a solvent such as ethanol. The solvent strips out the CBD Oil of the plant fibers, and then the maceration is run through a filter press as a slurry. The biomass is captured between the plates, and the extracted cbd oil can be purified and distilled.
The same filter press that is used for Ethanol Extraction can be used to Remove Chlorophyll. After the filter press is cleaned, Activated Carbon is added as a body feed or as a filter press precoat. The extract is run through the filter press capturing the Chlorophyll and Activated Carbon.
If you are using CO2 Extraction and a Buchner Funnel is slowing you down. A filter press will provide a better and more efficient method to remove unwanted waxes and lipids. Typically a filter aid is added to the slurry as a body feed or as a filter press precoat. This will help prevent blinding on the filter cloths. It also should be noted, that a Met-Chem Filter Press is designed to handle Very Cold Temperatures.
Met-Chem can manufacture a new filter press to help extract CBD oil. Each filter press will be designed to your specifications. The manifold and piping can be constructed using, but not limited to CPVC, Stainless Steel, and Food Grade Stainless Steel. As your business grows, our filter presses can be expanded by adding additional filter plates, reducing the need to purchase new costly equipment.
