从生物质中提取CBD的三种最常见方法

CBD提取我们看到越来越多的业务more frequently among our customers. That is no surprise, given that the federal government legalized industrial hemp and CBD products in the 2018 farm bill. A general acceptance of medical marijuana in most states only increases the need for reliable CBD extraction methods.

从生物质中提取最大的CBD比挂接植物油提取器并按下一些按钮更为复杂。另一方面，原则上并不是非常复杂。几代人已将CBD提取的三种最常见方法用于其他形式的植物油提取方法。这些方法是：

• 溶剂萃取
• steam distillation
• 二氧化碳提取。

If your company is involved in processing industrial hemp for the purposes of extracting CBD, we invite you to contact us to learn more about our equipment. In the meantime, you will find a brief discussion of all three extraction methods below.

1.溶剂提取

溶剂提取是通过将生物量与某种形式的溶剂混合而分离其理想成分的数百年历史的实践。溶剂是一种破坏植物寿命的材料，从而释放了其中的化合物。

Olive oil and similar botanical oils are natural solvents known for centuries. More recently, extraction operators turned to ethanol due to its greater efficiency. Modern operators prefer synthetic solvents thanks to their lower cost. Butane and hexane are two popular options.

溶剂提取的两个优势是效率和相对安全。不利的一面，溶剂提取通常会导致CBD油一致。与蒸汽蒸馏和二氧化碳提取相比，溶剂提取也更加细腻。

2.蒸汽蒸馏

蒸汽蒸馏还可以追溯到几个世纪以来。这是一个非常简单的过程，结合了热量和水以产生蒸汽。将蒸汽引入蒸馏箱中的生物质。热量导致植物材料释放其理想的化合物，而蒸汽则将这些化合物带到冷凝器等待的水箱顶部。

冷凝器产生由CBD化合物以及蒸汽中的冷凝水组成的混合物。最后，将所得液体蒸馏以分离液体混合物。您最终会获得与蒸馏水完全分开的全光谱CBD产品。

Steam distillation is preferred by operators looking for a low-cost option that is easy to implement. Unfortunately, steam distillation does not provide consistent results. It’s also not very efficient.

3.二氧化碳提取

二氧化碳提取可以说是三种CBD提取方法中最复杂的。它涉及使用超临界二氧化碳，这是一种二氧化碳的形式，它既显示气态和液体特性。超临界二氧化碳有效地渗透生物质，以相当有效地提取其理想化合物。

Where steam distillation relies on heat and steam, CO2 extraction relies on heat and pressure. Supercritical CO2 acts almost as a solvent to separate CBD oil from plant material. Then it’s a matter of capturing the resulting liquid and separating it into its various components.

CO2提取需要大量的知识和经验。这也是提取CBD的最一致的方法。最后，二氧化碳提取效率且快速。最大的缺点是需要昂贵的提取设备。如果您要依靠二氧化碳提取，请为大量投资做好准备。
