With the cannabis extraction machine, you have a tool that focuses on tasking out cannabinoids and other ingredients from the cannabis plant and allows you to add them together in the oil mix. 

One of the many similarities between cannabis oil extraction and other manufacturing processes is that there’s not necessarily a singular approach that guarantees success. 

At the same time, the fact that you have different extraction methods also means that there are different types of cannabis oil extraction machines for home use. And, each type will come with its own bespoke components. Here’s a quick breakdown of the different types and what makes them up: 

Parts Of A Cannabis Extraction Machine

Closed-Loop Extraction Machines

Probably the most popular type of weed oil extractor machine is the closed-loop system. This machine comes with the following components: 

  • An Extractor Apparatus: Here, you have the vessel where you place the cannabis plant and get it ready for extraction. It needs to be sealed since it will hold both the plant material and the solvent.
  • A Solvent Tank: This is the tank where you store the solvent that will be used in the process. And as you can imagine the solvent will be very useful in the extraction process. 
  • The Recovery Pump: When you’re done with the solvent, you’ll need to get it back. This is where the recovery pump comes in. 
  • A Collection Chamber: Finally, you have the collection chamber. Once the solvent is evaporated and you’ve gotten the cannabis oil, you keep it here and send it out for collection.

CO2 Extraction Machines:

CO2 collection has also quite emerged as a popular method for cannabis oil extraction. The weed oil extractor machine used in this method tends to consist of the following parts: 

  • The Extraction Vessel: As expected, this part holds the carbon that will be used for extraction. 
  • The Separator Component: Once the extraction process is done, you’ll need to place the extracted compounds and the carbon in separate places. And, this is where the separator comes in handy. You’ll need to recycle the carbon for additional use, but that’s a different step.
  • A Collection Vessel: Like the previous types of machines, you also need a collection vessel where you place the oil that you’re left with.

Rosin Press:

The rosin press makes use of heat and pressure to handle cannabis extraction. If you’re working with this cannabis extraction machine, you generally have some of the following components to work with: 

  • Heat-Infused Plates: These are plates that generate heat energy. When they are activated, they generate enough heat and pressure for you to simply apply on the plant. This method squeezes out the plant, allowing you to harvest the oil you need.
  • Collection Plates: As soon as you have your cannabis oil, you can collect it without stress using this component.

A Rotary Evaporator

Another interesting way to get the cannabis oil you need from the plant is to spin it. And this is where the rotary evaporator cannabis extraction machine comes in. The machines are very effective, and they come with the following parts: 

  • A Spinning Flask: First, you have a container that holds your plant and your solvent. The container looks like a flask, hence the name. And once you spin it, heat is generated to really kickstart the extraction. 
  • The Heating Bath: You also have a heating bath that provides the right amount of heat energy of the solvent to evaporate and the oil to be separated. 
  • The Condenser: The evaporation process is done, but you don’t need to throw the solvent away. A condenser allows you to collect it, and then make use of it time and again. So, it’s also resource-efficient. 

Ultrasonic Solvent Extractor 

If you want to go by this process without any heat content, then you could get the ultrasonic THC extractor instead. They come in two major parts: 

  • The Ultrasonic Probe: This component provides ultrasonic waves, which help to disintegrate cell walls and make the extraction process much quicker. 
  • Extraction Tank: As usual, you place both the solvent and cannabis plant material here so they can be extracted and further processed. 

Why You Need A Cannabis Extraction Machine

Machines have become a critical part of production. And as you can imagine, the marijuana oil maker has also been able to make cannabis oil extraction faster. Sure, you could do things manually – but, here are a few reasons why you would need a machine: 

Improving Operational Efficiency 

The first and most important reason why machines are vital is that they make your work easier and faster. Would you rather extract cannabis oil by hand or use a machine to improve speed?

Your Product Is More Consistent 

A machine also provides a way for you to ensure a more consistent product. And in a world where consumers are especially perceptive, this can be very important. 

Make Different Product Samples 

With extraction machines, you will also be able to create different cannabis products. Sure, cannabis oils are popular – but, manufacturers can also create pills, tinctures, waxes, and much more.

Control The Creation Process

Another important benefit of cannabis oil extraction machines is that they allow you to better adjust and control the important factors that affect the extraction process. From solvent ratios to temperature and more, accurate control over these factors makes work incredibly easier for you. 

Scale At Your Pace

A cannabis oil extraction machine makes it very easy for you to produce the exact number of cannabis you want. Whether you’re fine with small-scale production or want to expand, you’re free to do that when you want. 

How Cannabis Extraction Machines Work

Just as we pointed out, you don’t have to follow a singular extraction process. You have different options to consider, and each of them has its workflow. 

Solvent-Based Extraction 

For most people, the solvent-based, closed-loop process is what they go with first when they want to extract cannabis oil. So, what is the process here? Well, we’ve provided that below

Your First Step Is Loading The Extractor 

Well, before you put the cannabis into the THC extractor vessel, you need to make sure that the plant is of the highest quality. When you ascertain that, feel free to add it to the vessel.

Add The Solvent To The Mix

The next step is to make sure that your solvent is properly added to the plant. Considering that the solvent tends to be what makes the reaction possible, you can understand that it is very important. 

Some manufacturers choose carbon or butane. But, whatever you select, ensure that it can properly dissolve the components in the plant. Once it is added, you can move on

Let The Extraction Begin

As soon as the solvent moves through the entire plant material, it should be able to dissolve the compounds and create the right solution. For this extraction to work, you will need to maintain proper control over parameters like pressure, temperature, etc. Then, it should be easier for the marijuana oil maker to work.

Separate The Solvent From The Compound

Following the extraction process, you will now need to separate the solvent from the plant material. Remember – the solvent here will already contain the dissolved cannabinoids and other associated compounds. 

For the separation to work, you will need to properly combine temperature adjustments and pressure differentials. 

Take The Byproducts Separately

You’ll need to collect the extracted compound and the solvent. Do this in different chambers, but you want to leave a little bit of time for the concentrated cannabis oil to accumulate. 

Get Your Solvent Back 

The beauty of the cannabis oil machine in the closed-loop system is that you can also collect the solvent. This process allows you to use the solvent again in a different extraction cycle, thus increasing efficiency to a considerable degree. 

We Recommend Purifying Your Product

This isn’t compulsory per se, but if you want to improve the quality of your end product, you’ll need to ensure that you take out residual solvents and impurities from the oil.

Package & Collect Your Product

Your cannabis oil is now ready! All you have to do is package it, and you can ship it out for collection.  

CO2 Extraction Process

Another popular method for cannabis oil extraction is CO2 extraction. The method is especially popular because it allows you to create quality oils without necessarily leaving any harmful residues behind. 

For this process to work, here are the steps you will need to keep in mind:

Prepare Your Cannabis & Load It Up 

Just as you would do with the closed-loop method, you can find your cannabis and place it in the right vessel. Remember that the vessel here is designed to handle high pressures, and it functions as part of the entire system. 

Add Pressure To The Mix

Next, you will need to pressurize carbon dioxide to a critical state for the weed oil extraction machine to work. Here, the carbon will show properties of both a gas and a liquid, thus making it a highly effective solvent for extracting the CBD compound and others needed to form the oil. 

Follow The Extraction Process

Introduce your supercritical CO2 to the extraction vessel. This interaction will cause the cannabinoids and other materials to be dissolved, thus creating the cannabis solution. 

Separe Your Byproducts

Pass both the compounds and the CO2 into a separation vessel. Here, you would need to adjust both pressure and temperature conditions to separate both components. The compound is left in the vessel, while the CO2 is taken back to the CO2 reservoir to be reused if necessary 

Collect Your Cannabinoids

Now that the cannabinoids and terpenes are in a vessel, you can collect them and allow the concentrated CBD oil to accumulate. 

Process Your Solution 

In some cases, you might need to perform steps like winterization to take out lipids and waxes from the solution even after the cannabis oil machine has worked. You ensure that these unwanted components can leave the solution, and then you can filter it out one last time. 

At the end of it all, you’re left with a concentrated cannabis oil product that will have both CBD and terpenes. You can control the specific composition of the extract by adjusting formulation parameters, but that shouldn’t be much of an issue for you. 

Considerations for Choosing a Cannabis Oil Extraction Machine

Given that you have so many options available to you when it comes to a cannabis oil extraction machine for home use, it is important to make the right choice when deciding. With that in mind, here are a few important things to consider:

How Are You Extracting The Oil? 

Before anything else, you want to make sure that the weed oil extraction machine you choose works well with your chosen extraction method. Choose the machine that is most effective and safe, so you won’t have any challenges.

How Much Oil Are You Producing? 

Your scale of production will also determine what you work with. There are different sizes of machines available, so work with one that meets your production scale. 

Think Of The Automation Features

An abundance of automation and control features means that you will be able to get a more seamless, effective production process overall. 

Available Safety Protocols

You want to make sure that your machine has the right safety features. This is especially true if you’ll be working with flammable solvents. The very last thing you want is for an accident to spoil things, and your machine can help you prevent that.

How Do You Recover Your Solvent? 

It’s important to examine the available solvent recovery system. The more efficient the system is, the easier it will be to reuse the solvent and save money. 

How Easy Is It To Use? 

As you would imagine, we’d recommend that you work with a machine that won’t be much of a chore to use. At the same time, consider the machine’s maintenance structure and choose a machine that won’t stress you too much from this standpoint. 

How Much Is It?

Working with a budget? Then make sure you choose a machine that works within it. Remember – the fact that a machine is cheaper doesn’t necessarily mean it is the right choice. Focus more on quality than anything else.

Techniques For Cannabis Oil Extraction Processes

Finally, let’s take a quick look at some popular techniques that manufacturers tend to employ when trying to separate the cannabis plant from the desired product. Here, you generally have two main categories: solvent-based and non-solvent-based operating methods. 

Solvent-Based Cannabis Oil Extraction Processes

Under this incredibly broad category, we have some of the following options: 

CO2 Extraction 

With CO2 extraction, the objective is to make use of supercritical CO2 as a solvent. The application of this material leads to the removal of cannabinoids and terpenes from the cannabis plant, leaving you with your oil byproduct. 

CO2 extraction is beneficial because it improves extract quality while also providing you with better control over the parameters of the process. That said, you also need to get a  lot of pricey CBD machinery and equipment, and the process needs some time to master and get used to. 

Hydrocarbon Extraction Process

Here, you get a hydrocarbon – maybe propane or butane – as the solvent. It dissolves the terpenes and cannabinoids from the material, which you can go ahead to process. 

This process is beneficial because it is efficient and can be achieved pretty quickly. But, you also need to be careful with flammable hydrocarbons and ensure that you handle the equipment well. 

Ethanol or Alcohol-based Extraction 

The use of ethanol requires contact with the cannabis plant. You let the plant soak, allowing the ethanol to squeeze the cannabinoids from the plant. 

Ethanol extraction is beneficial because the dangers are relatively low. At the same time, you don’t necessarily need to spend so much on equipment. That said, you would need to be careful not to extract compounds like chlorophyll as part of the process. 

Non-Solvent Extraction Processes

As for the extraction processes that work without the need for a solvent, you have some of the following: 

Using The Rosin Press

With this process, you apply adequate levels of heat and pressure to the cannabis plant. This pressure squeezes the oil, leaving you with a suitable byproduct. 

The rosin press is pretty simple, and it can be a quick process. Plus, if you’re handling a small-scale production plant, then this machine is quite ideal. But, the fact that yields tend to be lower means that this process might not be so scalable. 

Ultrasonic Extraction 

When you employ this process, you’re essentially making use of ultrasonic waves to reduce the walls of the cells in the cannabis plant. As the walls break down, you will find it considerably easier to extract the compound and be done with the whole process. And, you get to do that without adding any solvent. 

You get a great deal of speed from this process. But, you also have to deal with overly expensive equipment


Cannabis oil extraction is a critical step in the process of ending up with the CBD oil that many of us love. The process can be varied, and you will need to consider a lot of actors when conducting it. But, when done right, the results are quite impressive.
