Extraction Equipment for Plant Compounds & Carrier Oils

Winterisation and residual solvent removal

When it comes to the field of essential oil and natural product extraction, the processes of winterisation and purification play crucial roles in ensuring the quality and safety of crude extracts.

Winterisation is a procedure primarily used to remove lipids, waxes, and other impurities from crude oils or extracts. This is typically accomplished by cooling the extract to a low temperature, where undesired components solidify and can be filtered out, leaving behind a purer product. The equipment designed for winterisation needs to provide consistent cooling and efficient filtration, allowing for the maximal retention of desirable compounds while minimising losses.

Another essential aspect of processing crude extracts is the removal of residual solvents, which can be potentially harmful if left in the final product. Solvent removal processes involve various techniques that vary in complexity and efficiency, depending on the type of solvent and the nature of the extract. Common techniques include rotary evaporation, vacuum distillation, and thin film evaporation, each of which has unique benefits and challenges.

The equipment used in these processes must be carefully designed and operated to ensure that all residual solvents are eliminated effectively, guaranteeing the safety and integrity of the final product. Properly managing both winterisation and solvent removal is vital in producing high-quality, safe extracts that meet industry standards.
