CBD Extraction and Oil Filtration Machine

Sanitary Heat Exchangers for CBD

The extraction of cannabis oil is a meticulous process that demands precision and control, especially in thermal management. In the CBD extraction industry, heat exchangers' primary function is to regulate processing temperatures with high accuracy, preserving cannabinoids, terpenes, and other delicate compounds in the product. Sanitary-grade shell and tube heat exchangers are widely used due to their efficiency and reliability.

These units are custom-designed to meet the specific needs of cannabis oil production, enabling precise cooling and heating during extraction and post-extraction processes. This setup provides optimal control of the extract’s temperatures, effectively preventing thermal degradation and ensuring consistent quality in the final product.

The robust construction of shell and tube exchangers ensures they withstand the rigorous demands of continuous operation and meet the stringent sanitation standards required for product safety. The versatility of these heat exchangers allows for customization of materials, sizes, and configurations to suit various extraction methodologies. Consequently, they are an indispensable component in the CBD extraction industry, where effective heat transfer is key to producing a high-quality product.

CBD extraction involves several critical steps using advanced equipment to ensure high-quality product yield and efficiency:

CBD extraction involves several critical steps using advanced equipment to ensure high-quality product yield and efficiency:

  • Preparation: Raw cannabis material is prepared by grinding or milling to increase surface area for extraction.
  • Extraction: CBD is extracted using solvents like ethanol or hydrocarbons in specialized extraction vessels.
  • Cryogenic Cooling: Solvents are chilled to subzero temperatures using heat exchangers (e.g., plate or tubular) to maximize extraction efficiency.
  • Evaporation: After extraction, solvents are evaporated in heat exchangers, separating CBD oils from the solvent.
  • Condensation: Vapors from the evaporation process are condensed back into liquid form for solvent recovery and reuse.
  • Filtration: CBD oil undergoes filtration to remove plant waxes and impurities, enhancing purity.
  • Distillation: Further purification through distillation separates CBD from other cannabinoids and compounds.
  • Winterization: CBD oil is mixed with ethanol and frozen to remove fats and lipids.
  • Decarboxylation: Heating converts cannabinoid acids (e.g., CBDA) into active cannabinoids (e.g., CBD).
  • Testing: Final CBD extract is tested for potency, purity, and contaminants before packaging.

Each stage requires precise temperature control and specialized equipment like heat exchangers to optimize extraction efficiency and product quality in the CBD extraction process.

CBD extractors are specialized machines used to remove cannabis oil (CBD) from hemp or cannabis plants. They use CO2, ethanol, or hydrocarbon extraction, to isolate CBD and other beneficial compounds from plants. The quality, potency, and purity of the CBD product are all impacted by the extraction process.



CBD extraction heat exchangers are used to regulate processing temperatures and to maintain cannabinoids, terpenes, and other delicate chemicals in finished CBD products. They stop heat degradation and enable producers to acquire a concentrated form of CBD while eliminating contaminants. CBD extractors are essential for the production of oils, tinctures, candies, and other CBD products. Additionally, CBD heat extraction devices adhere to stringent safety regulations.

Cannabis extraction machines require the precise control and accuracy heat exchangers provide. The goal is to create a pure and consistent concentrated product. CBD extraction machines use different methods to achieve this including:


  • CO2 Extraction: This method extracts CBD without the use of solvents by using pressurized carbon dioxide. To extract CBD from plant material without leaving residues, CO2 is transformed into a supercritical fluid that functions as both a gas and a liquid.
  • Ethanol Extraction: CBD and other cannabinoids are extracted from plant material using ethanol as a solvent. The ethanol later evaporates, leaving potent CBD behind. Large quantities of CBD extract are produced using this quick and efficient process.
  • Hydrocarbon Extraction: This technique extracts CBD by using hydrocarbons as solvents. Strong, premium extracts can be obtained using hydrocarbon extraction, but handling the finished product carefully is necessary to eliminate all solvents.
  • Oil Extraction: In this easier technique, CBD is extracted into an oil by heating plant material with a carrier oil (like coconut or olive oil). This process is used for small batches.
  • CBD extraction machines maintain proper temperatures, pressures, and purification steps for each system. Extracted CBD is then refined and purified to create CBD products.

Filtration of CBD oil is regarded as a critical refinement step following extraction rather than the most effective extraction technique. CBD is extracted from plants using the best extraction techniques, such as CO2 and ethanol extraction.



The extract is then purified using filtration. By filtering out contaminants like plant waxes, chlorophyll, and other undesirable substances, the purity, appearance, and flavor of the final CBD oil is improved. Filtration enhances the extraction process by yielding a pure, superior CBD product, even though it is not truly an extraction method.

By maintaining the proper temperatures during the extraction process, a CBD extraction chiller preserves the strength and quality of CBD. Maintaining a low temperature during processes like ethanol extraction minimizes the extraction of undesirable substances like chlorophyll, which compromise the end product's purity and flavor.



Chillers provide a more concentrated extract by preventing heat buildup, which can break down delicate terpenes and cannabinoids. Chillers improve performance for large-scale operations by accelerating the extraction process and lowering the need for further refinement by maintaining a regulated cool environment. CBD extraction chillers support higher-quality CBD extracts with fewer impurities.

The optimal CBD degradation temperature is around 320°F to 356°F. Exposing CBD to temperatures within or above this range for extended periods can cause degradation, resulting in less potency and reduced effectiveness. To preserve CBD’s therapeutic properties, keep it below this temperature range during processing, storage, and usage. Lower temperatures, especially in extraction and storage, maintain CBD’s integrity, ensuring a more potent product.
