A filter drier captures moisture and contaminants during the recovery process of the extraction solvent as it passes through the molecular sieve on its way to the condenser coil or recovery tank. This filtering process combines the micro-porous 2500 mesh (5 micron) gasket which excludes dust particle contaminants. The remaining vapor passes through the gasket into the stainless steel cannister which is commonly filled with a dessicant to remove moisture. A drier filter cannister typically consists of:
A molecular sieve relies upon a method called physical adsorption (as opposed to absorption - chemical integration). Adsorption is when one substance is held inside another by a physical bond. In a porous dessicant such as silica gel, activated clay or charcoal, water is removed through the attraction of thin layers of water molecules to the surface of the dessicant. Dessicants by their nature are very porous and thus have a lot of surface area to attract a large volume of water molecules.
Glacier Tanks makes every attempt to comply with both state and federal laws. Because marijuana and cannabis extraction is prohibited by federal law, Glacier Tanks is not able to offer advice or support regarding cannabidiol (CBD) or tetrahydrocannabinol (THC) extraction. Glacier Tanks' extraction equipment is appropriate for a broad range of botanical extracts such as lavender and essential oils. However, Glacier Tanks expressly does not guarantee that its equipment is suitable for or will perform in any particular way with regard to cannabis (CBD or THC) extraction.
