Cannabis / Hemp Filtration

Filtration often goes hand-in-hand with winterization. The fats, waxes, and lipids that precipitate during the winterization step are removed via filtration systems.

Filtration

Removal of unwanted compounds and refinement of cannabis extract

Solvent Recovery

Reclaim solvent to perform further extractions, winterization, or other post-processing techniques

Degas/Decarb

Polish and activate crude oil for further refinement

Distillation

Purification into a highly concentrated and refined cannabinoid oil

Isolation

CBD isolate is used for herbal supplement and end-product applications

Remediation

THC, heavy metal, pesticide, and color remediation

Formulation

Preparation into tinctures, topicals, vaporizer cartridges, water-solubles, and other consumer focused end-products

Extraction

Crude oil is extracted directly from plant material

Winterization

Precipitation of inactive compounds

Filtration Solutions

FP1 Filter Press

The FP1 is an industrial-scale filter press.

The FP1 is ideal for the post-winterization filtration of crude oil. Utilizing positive pressure, the FP1 can remove fine particles and small particulate from winterized crude solutions efficiently.

  • Advantage

    Easier to use, less labor-intensive, and higher throughput compared to candle or bag filters

  • Certifications

    C1D1, GMP Compliant

4-Stage Lenticular Filter Skid

This optimized 4-stage filtration skid is designed for filtering ethanol solution from biomass extraction.

The lenticular filter includes four different types of filters in one filtration assembly skid to handle all types of filtering needs. It can be used for pre-filtration, particulate and haze removal, fat and wax removal, decolorization, and fine particulate removal.

  • Filtration Type

    2x Lenticular Housing, Bag & Cartridge Housing

  • Standard Features

    Air-driven Diaphragm Transfer Pump

Filtration

Creating viable cannabis consumer products requires the removal of unwanted fats, waxes, lipids, and pigments that would otherwise ruin the taste, flavor, and appearance of these extracts and end products. Filtration and color remediation are two processing steps that allow for the removal of these unwanted compounds while also refining the cannabis extract to make it more appealing for consumers.

Cannabis & Hemp Filtration

Filtration is often associated with the winterization step in the chain of cannabis processing. During winterization, fats, waxes, and lipids will coagulate and must be filtered from the solution before moving onto the solvent recovery step. But, there are other steps in the process that might require filtration. During the initial extraction process, there are often one or more in-line filters that are utilized for fine particulate removal.

Types of Filtration Systems

To achieve efficient filtration or color remediation, it is important to utilize the right type of equipment. There are several styles of filtration systems and it is important to select the right type of system to achieve the desired results.

The most common type of filtration system is the vacuum-assisted Buchner Funnel. This type of filtration system comes in a variety of sizes and is most commonly used in laboratory-scale cannabis production. Buchner funnels can be used for a variety of types of filtration and work well for both fat and wax removal as well as color remediation using media. The only downside with Buchner funnels is they do not scale very well. In processing facilities that need to filter hundreds of gallons of solution, a Buchner funnel would be too time-consuming to be efficient.

Another common type of filtration system is a bag-style filter. Bag filters usually include a pumping mechanism as well to quickly move the solution through the filter. Bag filters are a great choice for fine particulate removal or removing media from a solution. Bag filters can handle large amounts of solution.

Another similar type of filtration system is a lenticular filter. Lenticular filters have many of the same strengths as bag-style filters in that they can handle high throughput and remove a variety of compounds from the solution. Lenticular filters take this a step further by maximizing the surface area of the filter, meaning more solution can be passed through the filter before it needs to be cleaned or replaced.

Lastly, filter presses are another type of common filtration system used in the cannabis industry. Filter presses utilize plates that are pressed together using a hydraulic pump. The solution is passed through the filter by a pumping mechanism and creates a cake on the filter plates. Filter presses can handle large amounts of solution and work well for very fine filtration applications.

Filtration Conclusions

Filtration is a very important aspect of cannabis processing. Without effective filtration, it will be impossible to create viable end products for consumers. The best types of filtration systems usually utilize multiple types of filters to increase throughput as well as fine filtration capabilities. At Lab Society, we offer a variety of types of filtration systems such as those described above. It is best to identify what compounds need to be removed from the solution to properly choose the type of filtration system needed. Whether you are trying to remove fats, waxes, lipids, particulates, or pigments, we have a filtration solution to match your throughput and processing capabilities.
