Cold ethanol extraction equipment

Cold ethanol extraction equipment is used to extract compounds from plant material using ethanol as a solvent. This equipment is commonly used in the production of dietary supplements, essential oils, and other products made from plant-based materials.

In the cold ethanol extraction process, the plant material is soaked in ethanol for a specific length of time, typically at a low temperature. The solvent is then filtered and separated from the plant material, and the extract is collected. The extract may then be further processed to remove the solvent and concentrate the extracted compounds.

Cold ethanol extraction equipment is used to facilitate this process by providing the necessary vessels, filters, and other tools to hold, filter, and evaporate the solvent and extract. The specific equipment used will depend on the specific needs of the extraction process, such as the size and type of plant material being used, the desired purity and concentration of the extract, and the available resources and budget.

Q How long does the ethanol centrifuge extraction cycle take?

A The ethanol extraction cycle includes: entering ethanol --> low-speed rotating extraction --> high-speed rotating spin drying --> reclaiming. Most customers choose 30mins as the time for a batch of extraction. There are also customers who choose 40mins or 20mins. The longer the extraction time, the higher the yield of the extract. However, the lower the proportion of CBD in the extract, the processing difficulty and product purity of the back-end will of course be affected. The choice in the process is all up to you.

Q Customers want to evaporate ethanol, what equipment can be recommended?

A We can choose to rising film evaporator, wiped film evaporator, falling film evaporator, rotary evaporator. The rising film evaporator has high efficiency, and the size of the evaporator is smaller under the same processing capacity, which is conducive to saving space and improving efficiency. The solvent collection rate of wiped film evaporator is high, no waste, and sometimes even can be passed over again, so the speed is fast. Falling film evaporator usually has to be repeated twice, and there will be more waste and residues, need to be further removed by the decarboxylation process. The price of rotary evaporator is economical & affordable, 1L-100L wide capacity range can be freely selected, but the overall speed is slower compared with the first three types evaporators . If be used in laboratory or home, then rotary evaporator is recommended.

Q What is the general process for the start of cryogenic ethanol extraction?

A The dried hemp flower leaves are crushed and dried --> Cryogenic ethanol extraction process (The CBD extraction rate is about 90%) --> Multi-stage filter to remove cellulose and FAT --> Rising film evaporator for desolventize, also be called alcohol recovery --> Decarboxylation to remove residual ethanol, convert CBDA to CBD --> Wiped film molecular distillation equipment for separation & purification to get pure cbd oil --> Crystallization, Repeated crystallization filtration or adding chromatographic treatment after crystallization filtration can increase the purity to 99% --> Get CBD dry powder through vacuum drying oven.

Q What is the general process for the start of CBD supercritical extraction?

A Co2 Supercritical extraction --> Dewaxing and impurity removal (wax refers to macromolecular organic impurities) --> Evaporation to remove solvent --> Decarboxylation --> Short path wiped film distillation equipment for separation --> Crystallization filtration --> Chromatographic separation (optional) --> Drying (vacuum drying oven).

Q How is biomass put into the centrifugal extractor? In a bag?

A The filter bag has a zipper, just put the biomass directly into the filter bag, and then put the filter bag directly into the extraction chamber. We provide filter bags.
