Evaporating alcohol from oil without heat is possible and can be done in several ways. One way is to let the alcohol sit in an open container in a well-ventilated area for a few days. The time it takes to evaporate depends on the method used and the environment. Another way is to use a fan to increase airflow and speed up the evaporation process. However, it is important to note that direct sunlight can break down molecules, so it is recommended to keep the setup away from direct sun exposure. Building your own airflow evaporation system, such as an Alcohol Vanishing Apparatus (AVA), can also be a simple and cost-effective solution.

What You'll Learn
Using a well-ventilated room
Evaporating alcohol from oil without heat is possible, but it will take a while. One way to do it is to place the oil in a well-ventilated room. This method can be done by simply leaving the oil uncovered in a well-ventilated room for a few days. This technique eliminates the increased risk of flammability associated with using heat, but it is important to avoid inhaling the fumes.
To speed up the evaporation process, a fan can be placed in the room to increase airflow. This will help the alcohol to evaporate more quickly. However, it is important to ensure that the fan does not blow dust into the oil, as this could contaminate it.
When evaporating alcohol in a well-ventilated room, it is important to consider the air temperature and humidity levels. Warmer air will increase the volatility of the alcohol, causing it to evaporate faster. However, warmer air also tends to have higher humidity levels, which can slow down the evaporation process. Therefore, it is ideal to have warm, dry air in the room.
Additionally, the surface area of the oil exposed to the airflow will impact the evaporation rate. Increasing the surface area by using a shallow dish or tray can help speed up the process. It is also recommended to place the oil in a sunny spot, such as a windowsill, to take advantage of the heat from the sun. However, direct sunlight should be avoided as it can break down certain molecules in the oil.

Running a fan over the oil
It is important to note that direct sunlight should be avoided as this can break down longer molecules such as THC. Instead, the oil should be placed in a well-ventilated area, with the fan blowing over it, to ensure the alcohol evaporates. This method can be used to evaporate alcohol from tinctures, which are alcohol extractions used in herbal medicines.
One source suggests that a fan should not be used as it will introduce dust to the oil. However, other sources recommend using a fan to speed up the evaporation process. It is also recommended that the oil be placed in a warm place, such as a sunny window sill, to help speed up evaporation.
Evaporating alcohol at room temperature without heat removes the risk of flammability, but there are still risks involved. It is important to ensure the vapour is not inhaled, and to avoid introducing the vapour to an open flame, as this could cause a fire or explosion.

Using an Alcohol Vanishing Apparatus (AVA)
Prepare the Tincture
Start by preparing an alcohol-based tincture using a high-proof food-grade ethanol such as Everclear. Common tinctures include Green Dragon, Golden Dragon, THCA tincture, CBDA tincture, or cannabis root tincture. Ensure that you properly strain the tincture to remove any solid particles.
Set Up the AVA
The basic structure of AVA consists of a cube-shaped frame made from wire bookshelves. Obtain two wire bookshelves, each measuring 24" wide by 12" deep x 24" tall. Arrange them to form a cube that can accommodate trays of tincture. Make sure the shelves are made of wire to allow for adequate airflow while providing support for the trays.
Obtain Trays and Liners
Acquire large aluminum baking trays that are at least 2" deep. Avoid using pans with grease or strength ridges; instead, opt for flat-surfaced trays. These trays will hold your tincture during the evaporation process. Get a Teflon sheet to line the trays and protect them from the tincture.
Use a Fan for Airflow
Place a box fan at the bottom of the AVA structure. Set it to its lowest setting to ensure quiet operation. The fan will provide airflow, aiding in the evaporation process without generating excessive noise. Seal any gaps between the fan and the structure using weather stripping or foam to ensure an airtight seal.
Load the Trays
Fill your trays with the tincture, being careful not to spill any. Place two trays inside the AVA structure, ensuring they are securely positioned on the shelves. You can adjust the number of trays depending on your batch size, but it's recommended to not overload the AVA.
Evaporate the Alcohol
Turn on the fan and let the AVA do its work. The airflow from the fan will facilitate the evaporation of the alcohol from the tincture. The time required for complete evaporation will depend on various factors, including temperature, airflow, and the initial volume of tincture.
Collect the Concentrate
Once the alcohol has fully evaporated, you will be left with a potent cannabis concentrate. Scrape the concentrate from the trays and process it according to your desired end product. You can press it flat between parchment paper or store it in an airtight glass container, depending on your intended use.
Using AVA is a safe and effective method for evaporating alcohol from tinctures without heat. It is important to follow the instructions carefully and ensure proper airflow and ventilation during the process. Always be cautious when working with flammable liquids and avoid open flames or heat sources that could ignite the vapors.

Leaving the oil in direct sunlight
If you do choose to use this method, it is important to place the oil in a well-ventilated area to avoid an explosion. A fan can also be used to speed up the evaporation process, but be aware that this may introduce dust to the oil.
There are alternative methods to evaporating alcohol from oil without heat that may be more effective and safer. One method is to create an airflow evaporation system by following these steps:
- Wrap a wire bookshelf with plastic wrap, leaving the bottom and one side open for the fan and access.
- Seal the plastic wrap with duct tape and apply Velcro to the perimeter of the open side.
- Cut a square out of the plastic wrap and apply Velcro to the perimeter to create a door.
- Place a fan inside the bookshelf and put your oil in front of the fan to increase evaporation.
Another method is to freeze the oil and then mix and stir it for 30-45 seconds before filtering and evaporating. This method can also be combined with the airflow evaporation system to increase effectiveness.

Placing the oil in a warm spot
To evaporate alcohol from oil without applying heat, one method is to place the oil in a warm spot. This method can be done by placing the oil in a sunny spot, such as a windowsill, or near a heater or radiator. It is important to ensure that the oil is in a well-ventilated area to facilitate evaporation. A fan can also be used to increase airflow and speed up the evaporation process.
When using this method, it is crucial to consider the humidity levels in the air. Warmer air tends to have higher humidity, which can negatively impact the evaporation rate. Additionally, direct sunlight should be avoided as it can break down certain molecules in the oil.
It is worth noting that the time it takes for the alcohol to evaporate will depend on various factors, including the temperature, airflow, and initial amount of oil. By placing the oil in a warm spot and ensuring good ventilation, the evaporation process can be effectively carried out without the use of heat.
