A simulation‐guided tri‐spiral condenser design for enhancing lemongrass essential oil recovery.

We present a groundbreaking achievement in essential oil extraction, showcasing the development of a highly efficient tri‐spiral condenser for use in microwave‐assisted extraction (MAE) setups. This innovative condenser is specifically designed to swiftly cool vapors, optimizing oil yield during the MAE process. Our investigations demonstrate a notable improvement in oil purity, attributed to the expedited condensation facilitated by the tri‐spiral design. Traditional heat exchangers, like the Liebig condenser, fall short in efficiently handling the high vapor production rates of MAE. In response to this challenge, our tri‐spiral condenser design enhances condensation speed, resulting in a remarkable 12.2% increase in oil yield compared with the Liebig condenser (2.1% with tri‐spiral vs. 1.87% with Liebig), as validated by Gas Chromatography–Mass Spectrometry. Beyond elevating oil purity, our design holds promise for diverse applications requiring rapid cooling. This work not only advances laboratory practices but also contributes to the broader societal need for efficient and sustainable methods in the essential oil extraction industry. Practical applications: The innovative tri‐spiral condenser design, as elucidated in this article, presents significant practical applications, especially in the realm of lemongrass essential oil recovery. This breakthrough technology holds promise for the fragrance and cosmetics industries, where lemongrass essential oil is a valuable ingredient. The novel condenser design enhances extraction efficiency, leading to a higher concentration of essential oil with improved aromatic compounds. Cosmetic manufacturers can benefit from a more potent and fragrant lemongrass oil for skincare and aromatherapy products. Additionally, the pharmaceutical sector could leverage this advancement for developing therapeutic products harnessing the medicinal properties of lemongrass. By optimizing essential oil recovery, the tri‐spiral condenser design not only caters to the needs of the fragrance, cosmetic, and pharmaceutical industries, but also aligns with a broader trend towards sustainable and efficient manufacturing practices, ensuring the accessibility of high‐quality lemongrass essential oil for diverse applications.
