If you start using CBD oil, you may be asking yourself, "How is CBD oil made?" After all, if you're using something, you should know how it's made. Manufacturers currently use a variety of different equipment to create CBD oil. Different devices also have different characteristics depending on the method they choose.
 
When evaluating the dizzying array of CBD products on the market, you only need to know which process was used to narrow down your decision. For example, if you want to make sure that the pure CBD you use is free of any harmful substances, then you should use CBD that has been made through isolation methods. So do you know how to choose CBD oil manufacturing equipment?
 
The extraction line products provided by ZZKD include supercritical CO2 extraction equipment for sale, molecular distillation, stainless steel reactor, centrifuge, large cake filter, and cryogenic pump. Among them, in the manufacture of CBD oil, supercritical carbon dioxide extraction equipment, molecular distillation,lab scale Falling film evaporator and stainless steel reactors are the most commonly used. This article will focus on the advantages of these types of equipment in the manufacture of CBD oil.

Carbon Dioxide Extraction of CBD Oil

CO2 extraction equipment for sale:

CO2 extraction equipment for sale:Extracting CBD oil using supercritical carbon dioxide extraction technology is the most common commercial method, and one of the safest, to isolate CBD and other cannabinoids from hemp biomass. At room temperature, carbon dioxide is a gas. But under high pressure and temperature fluctuations, carbon dioxide liquefies while still maintaining the gas's hydrodynamic properties. In this "supercritical" state, carbon dioxide acts like a solvent, flushing the active ingredients out of the plant matter.
 
This method is very efficient because each compound can only be extracted by carbon dioxide under certain conditions. In the supercritical state, slight changes in temperature or pressure can fine-tune the extraction of CBD and other desirable botanical components. As the pressure dropped, a crude waxy substance rich in CBD, which was golden yellow, separated from the gas and deposited into a collection vessel. Afterwards, the golden oil undergoes a process known as "winterization", which purifies and refines the extract to enhance its quality and value. Vegetable waxes that are not suitable for inclusion in certain kinds of products are filtered out, resulting in a safe, clean, CBD-rich oil that is free of chlorophyll.
 
Supercritical carbon dioxide extraction requires expensive equipment and a lengthy operational learning curve. But unlike flammable solvents like ethanol or butane, carbon dioxide poses no fire or explosion hazard.
 

Solvent extraction method to extract CBD oil

The process uses ethanol to remove CBD from plants. It is faster than CO2 extraction method and does not require complicated equipment, ZZKD can provide you with simple and flexible equipment.
 

Falling Film

Lab scale Falling film evaporator is to add feed liquid from the upper tube box of the heating chamber, and evenly distribute it to each heat exchange tube through the liquid dispensing film forming device. Through the downward flow process, it is heated and vaporized by the heating medium on the shell side, and the generated vapor and liquid phase enter the separation chamber of the evaporator together. After the vapor and liquid are fully separated, the vapor enters the condenser for condensation (single effect operation) or enters the next effect evaporator as a The medium is heated to achieve multi-effect operation, and the liquid phase is discharged from the separation chamber.


The feed liquid of the falling film evaporator is added from the top of the evaporator, and descends in a film-like shape along the tube wall under the action of gravity, and evaporates and thickens in the process, and the concentrated liquid is obtained at the bottom. Falling film evaporators can evaporate materials with higher concentration and higher viscosity. Since the solution flows in a film-like manner in the single-pass type evaporator, the heat transfer coefficient is high. Low temperature differential evaporation can be used because the process fluid flows only by gravity and not by high temperature differentials.
 

Stainless Steel Reactor:

The stainless steel reaction kettle is to provide a reaction place and maintain certain conditions. The chemical reaction process is carried out in a predetermined direction to obtain a qualified reaction product. Almost all process equipments contain reactors, so how to choose a suitable series of reactors, establish better operating conditions, and design reasonable and reliable stainless steel reactors is of great significance to meet the growing needs of the process industry.


One is thermal evaporation heating: when the heating temperature of the reactor is lower than 100°C, steam below atmospheric pressure can be used for heating; the saturated steam temperature is between 100 and 180°C; when the reactor temperature is higher, it can be used High pressure superheated steam.
Plumbing: When the required temperature is not high, it can be used. The heating system is divided into two types: open type and sealed type. Open type, composed of circulating pump, water tank, pipeline, regulating valve, etc. When high-pressure water is used, the mechanical strength of the equipment is high. A serpentine tube is welded on the surface of the reaction kettle, and there is a gap between the serpentine tube and the kettle wall, which increases the thermal resistance of the reaction kettle and reduces the heat transfer effect.
 

Molecular Distillation

Short path distillation lab equipment is a distillation method in high vacuum. At this time, the mean free path of vapor molecules is greater than the distance between the evaporation surface and the condensation surface, so that the difference in the evaporation rate of each component in the feed liquid can be used to separate the liquid mixture. . Moreover, the distillation temperature of molecular distillation is low, and molecular distillation is operated at a temperature far below the boiling point. As long as there is a temperature difference, the separation purpose can be achieved. This is the essential difference between molecular distillation and conventional distillation. The distillation vacuum degree is high, and the molecular distillation device can obtain a high vacuum degree inside. Usually molecular distillation is operated at a very low pressure, so the material is not easily oxidized and damaged, and the degree of separation is higher. Molecular distillation can separate conventional and difficult to separate. substance.
