Why Is Efficient Citrus Oil Dewaxing and Lipids Removal Important?

 

Most citrus essential oils are extracted by cold pressing the rinds of citrus fruits. Naturally occurring waxes that originate in the citrus peels are solubilized during extraction and have a negative impact on the quality of the citrus oil, causing cloudiness upon precipitation. Various processors of citrus oils employ a variety of methods to separate the wax solids, including centrifugation, tank settling, diatomaceous earth (DE, Kieselguhr) filtration and depth filtration with cartridges, lenticular filters or filter sheets.

 

Insufficient final product quality, which often necessitates reprocessing of the oils in multiple passes through the filters, and impacts productivity. Process flow rates are often very low, or the installations require large sizing. Filters downstream often plug quickly. Replacing the disposable filters to allow batch completion is time-consuming, labor-intensive, and costly.

 

Proven and cost-effective solutions for de-waxing citrus oils

 

SUPRApak™ Plus Modules

SUPRApak Plus is the second generation of our SUPRApak filter series. Using advanced sealing technology to seal infiltrate to filtrate channels, its higher mechanical stability optimizes process safety while the high dirt holding capacity increases process time, reducing OPEX and improving the availability of the filter line.

 

SUPRApak PW Modules

Use for standard processes, the SUPRApak PW Series is available in multiple grades suitable for applications requiring fine, clarifying and coarse filtration.

 

SUPRApak PH Modules for ion-sensitive processes to prevent precipitation of crystals in the filtrate.

 

SUPRApak PZ Modules for lowest possible impact on high-quality products using 100% pure cellulose sheet media. 

 

Benefits of these solutions include: 

 

  • Reduction in process time compared to the use of depth filter cartridges

  • Single SUPRApak filter housing, providing improved filtration

  • Higher flow capacity and throughput consequences to “edge flow” configuration
