Why Is Efficient Wax and Lipids Removal Important?
Most citrus essential oils are extracted by cold-pressing the rinds of the citrus fruits. Naturally-occurring waxes which 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 necessitate reprocessing of the oils in multiple passes through the filters, are 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 is the second generation of our SUPRApak filter series. Using advanced sealing technology to seal unfiltrate to filtrate channels, it’s higher mechanical stability optimizes process safety while the high dirt holding capacity increases process time, reducing OPEX and improving availability of the filter line.
Use for standard processes, the SUPRApak PW Series are available in multiple grades suitable for applications requiring fine, clarifying and coarse filtration.
SUPRApak PH Modules for ion sensitive processes to prevent percipitation of cristals in the filtrate.
SUPRApak PZ Modules for lowest possible impact on high quality products using 100% pure cellolose 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
