What are rosin bags for?

In the context of plant oil extraction, a rosin bag refers to a specialised tool used in the process of making rosin, a solvent-less concentrate. Rosin is created by applying heat and pressure to plant material, causing the trichomes (resin glands) to release their essential oils.

A rosin bag is typically a small, heat-resistant bag made of mesh or fabric that contains the plant material. The bag acts as a filter during the extraction process, allowing the essential oils to pass through while holding back plant material and other impurities. The use of rosin bags helps produce a cleaner and more refined rosin concentrate.

Here's a general overview of the rosin extraction process using a rosin bag:

Material Preparation: Plant material is placed inside the bag.

Heat and Pressure Application: The rosin bag containing the plant material is then subjected to heat and pressure using a specialised rosin press. This process may involve using a hydraulic or pneumatic or automatic press.

Extraction: The combination of heat and pressure causes the trichomes to release their oils, which pass through the mesh of the rosin bag.

Collection: The extracted rosin is collected on a surface (such as parchment paper) beneath the rosin bag.

Using rosin bags in the extraction process helps to improve the purity of the final rosin concentrate by minimising the presence of plant material and contaminants. It's a popular method among extraction enthusiasts who prefer solvent-less extraction methods for their simplicity and the absence of potentially harmful solvents.
