Our engineer team who focuse on C B D field has upgrade the Column chromatography system, the result is that we will use very little amount of solvent and to remove more THC compound from the C B D crude oil, means that the content of THC residue becomes lower by using our new column chromatography system.
Dried hemp biomass---low temperatrue solvent extractor---falling film evaporator(solvent recovery)---winterizatioin(remove wax)---decaboxylation---short path distillation---chromatography column system(remove THC)---falling film evaporator---finished product of broad spectrum C B D oil---crystallization to get C B D isolate
Successful project cases:
Zhejiang Shuangzi Intelligent Equipment Co.,Ltd has 4 sucessfull project cases of C B D oil field, we have mature echnica experience for C B D oil production line. And we have another 2 lines are building for our USA customers.
The C B D oil extraction production line we already built and are going to build, according to our customers` requirements, to produce different finished product, the finished products are:
1. C B D isolate
2. C B D Crude oil(after the process of decaboxylation, gold oil)
3. Broad spectrum C B D oil(without THC)
Finished products test report:
Our customers C B D oil production lines run well, and they inform us that there finished product test well too.
The key date of the THC residual quantity content in C B D isolate and Broad spectrum oil is perfect, in C B D isolate, the THC content is less than 0.05%, some batch test result is THC free
Application of separation and purification of natural products
Development of small-scale test technology, magnifying research of pilotscale test technology, preparation of phytochemical standard products and contrasting products. Widely suitable for separating phenol, aldehyde, alkaloid, amino acid, steroid, terpene, flavone, quinine, organic acid, glycoside, glucide, nucleotide etc. pure products, such as: paclitaxel, tea polyphenol, ginkgo flavone, bamboo leave flavone and vitamin E etc.

Our factory has studied on C B D oil field for more than 3 years, we have our own professional experience to do the process of C B D oil extraction.
We adopt low temperature of solvent and ultrosonic continuous counter current extractor to extract C B D oil, equipped with ultrasonic facility, which has very high performance of extraction efficiency, also avoid to extract WAX.
Q3: What is the difference between C B D oil and hemp oil?
C B D oil and hemp oil come from different parts of the canabis plant. C B D oil comes from the whole industry hemp, mainly from the leafs and flowers, while hemp oil comes from its seeds.
Do the process of cold pressing on the seeds will get hemp oil.
C B D oil will adopt extraction process.
Q4: What is the difference of C B D, THC, full spectrum C B D oil and broad spectrum C B D oil?
After we get crude oil from the extraction process, we do winterization process and decarboxylation process, and then we get full spectrum C B D oil.
And then we do the process of short path distillation and column chromatography, the remove the THC, finally we get broad spectrum C B D oil.
Means that full spectrum C B D oil= broad spectrum C B D oil + THC
THC is the abbreviation of tetrahydrocannabino, which is one of the active compounds of industry hemp
C B D is is the abbreviation of cannabidio, which is one of the active compounds of industry hemp
Q5: Do your company supply turnkey project of C B D oil extraction?
Yes, we can manufacture and supply the complete set of C B D oil extraction production line.
We already has several successful projects of C B D oil extraction production lines.
Q6: What production capacity of your C B D oil production line?
Our factory ZHEJIANG SHUANGZI INTELLIGENT EQUIPMENT CO.,LTD can supply large rang of production line, from 50Kg per hour to 2000Kg per hour of dried biomass process capacity. Especially we have technical advantage for large scale production capacity.
Q7: How long of the lead time?
4-5 month.
Q8: Does your factory have C B D oil extraction project case?
Yes, we have. We have successful project cases in our local market, as well as in USA market.
For USA market, there are 6 engineers and 5 workers has visa of USA, they can easily visit USA for technical support and equipment installation.
