Decanter For CBD Hemp Oil Extraction Process

Cannabidiol (CBD for short) is a light yellow or white crystal, and its structural formula is shown in Figure 1. Molecular formula: C21H30O2, molecular weight: 314.47, boiling point: 187 ℃~190 ℃, melting point: 66 ℃~ 67 ℃, density: 1.040 g/cm3, refractive index: 1.5404. Almost insoluble in water or 10% sodium hydroxide solution, soluble in ethanol, ethyl ether, methanol, benzene, petroleum ether and other organic solvents.

Cannabidiol compounds have unique medical properties, and many of them have been widely used in medical and clinical fields.

Clinical applications include Analgesic, anti-anxiety, antibacterial, anti-cancer, anti-spasm, and anti-depression. Anti-emetic, anti-inflammatory, anti-insomnia, neuroprotective, and appetite stimulant.

Marijuana has high economic value and medicinal value, and more and more countries begin to explore the legalization of marijuana. In 2018, recreational marijuana (the drug) was legalized in Canada; That same year, the British government approved the use of medical cannabis. As of November 2020, 35 U.S. states and the District of Columbia had legalized medical marijuana.

Thirty-four countries, including Germany, Australia, Israel and South Korea, have fully legalized medical marijuana. With the deepening of research on industrial hemp, the legalization of industrial hemp will become a general consensus of the international community. In recent years, research results on the medical and clinical application of CBD have been published in an endless stream, and the extraction technology and equipment of CBD are also constantly updated. At present, the extraction technology of CBD reported at home and abroad is mainly solvent extraction.

The solid phase of hemp biomass stems and leaves were dried, crushed and extracted by ethanol centrifugation at low temperature. Centrifuge equipment used to be mainly screw press or basket centrifuge. Due to the small capacity of these devices and the inability to operate continuously, decanter centrifuges are mainly used as separation equipment.

ZK decanter centrifuge has the following advantages:

PLC automatic control, easy operation, continuous operation, large processing capacity.
