Leading Extraction Chiller Manufacturers

The four types of chillers used in the extraction process are evaporation, compression, condensation, and expansion. As with all chillers, these types of chillers manipulate the characteristics of a vapor. The function of a chiller is to remove heat from a fluid using a heat exchanger. The collected heat is removed using the fans of an air cooled chiller, or the water of a water cooled chiller.

The extraction process involves the basic elements of a chiller, which are high temperature and high pressure with a liquid solvent. There are various extraction processes, each of which is a different method for performing the same process and includes ethanol extraction, solvent extraction, and CO2 extraction.

Extraction Chiller Types

Extraction chillers are capable of reaching the extremely low temperatures that are required for the extraction process. They are designed to extract various chemicals and oils from plants to produce medicines, cosmetics, and dietary supplements. The types of materials extracted by extraction chillers have given them the name botanical chillers.

During the extraction process, various solvents, CO2, or ethanol are cycled through the fibers of plants at subzero temperatures, which have to be maintained at a constant and steady setting to avoid damage to the plants. Regardless of the process, all forms of extraction begin with leaves, roots, or the stems of plants.

Carbon Dioxide Extraction Chiller

Carbon dioxide extraction is a complex extraction method that is highly advanced and reliable. It uses a closed-door extractor with three chambers, with the first chamber containing CO2 in a solid form. The second chamber has leaves and plant material. The third chamber is the key chamber where the separation process occurs.

The process begins with the release of CO2 into the second chamber with the material to be separated. Then, in the third chamber, the CO2 rises and leaves the separated material at the bottom of the chamber. With carbon dioxide extraction, temperature and pressure are used to create phase changes in the carbon dioxide. As a tunable solvent, carbon dioxide can extract many types of substances. As it is manipulated, it causes compounds to separate from their plant material.

There has been a growing interest in CO2 extraction, especially in the production of THC and CBD. The process is completed using a liquid solvent that passes through the cannabis plant material. Under stable temperature conditions, the process preserves the non-psychoactive attributes of the THC and CBD materials.

Ethanol Extraction

Ethanol extraction uses ethanol as the solvent, which is combined with biomass, where the ethanol pulls out the desired compounds. The extracted elements are in the form of crude oil. The process of ethanol extraction has been used for centuries since ethanol evaporates quickly, leaving the extracted oils.

The process of ethanol extraction is safe and offers outstanding results. The main focus of ethanol extraction is immersing the plant material in ethanol. Then, the blended plant material and ethanol are left in the extraction chiller overnight at radically low temperatures. During the mixing, blending, and combining process, separation happens, and the desired compounds are extracted.

Solvent Extraction

Solvent extraction is a simple and cost-effective method that uses ethanol and butane. The plant material is dissolved in the solvent that dissolves the oil and washes the oilseeds using chemical extraction. The process is referred to as liquid-liquid extraction (LLE), which is the extraction of one liquid from another. It is an ideal method for large-scale production.

The process of solvent extraction is similar to ethanol extraction. As with ethanol extraction, the plant material is soaked in petroleum ether, methanol, or hexane to separate the botanical oils. The substances and chemicals extracted from plants are part of the pharmaceutical, fragrance, food, and medical industries. Solvent extraction is an ancient process that goes back thousands of years. It has been enhanced and made safer in the modern era using the controlled environments created by extraction chillers.

Major Features of Extraction Chillers

Chillers are initially divided into air cooled and water cooled. Air cooled chillers require a great deal of power but are compact and portable. Water cooled chillers are less expensive but have a cooling tower and take up a great deal of space. Aside from these basic aspects of chillers, there are other considerations regarding extraction chillers.

• Temperature – The temperature range is an essential part of extraction chillers and must be between -40 °F to -80 °F (-40 °C to -62 °C).
• Size – The sizing process can be difficult and necessitates careful consideration. An undersized chiller will not supply sufficient cooling, while an oversized one can be inefficient.
• Refrigerant – The most recent trend in refrigerants has been toward natural refrigerants due to environmental considerations.
• Compressor Size – The heat load and coolant temperature determine the size of the compressor. A higher heat load and lower-set point temperatures can result in extreme power consumption and cost.
