Overview

Pure-Flo® Supreme 55 by Oil-Dri is a surface-modified bleaching earth developed for edible-oil refining, process-oil clarification and moderate color reduction. It is positioned for processors seeking dependable routine purification, practical treatment economics and consistent filtration across compatible fats and oils.

Supreme 55 provides a useful bleaching-earth option where moderate adsorption activity is appropriate. Its fine mineral-powder form promotes close contact with the oil during bleaching before the spent adsorbent is removed through compatible filtration equipment.

Bagged pallet configuration: 40 × 50 lb (22.68 kg) bags — 2,000 lb (approximately 907 kg) net per pallet.

Bulk format: 2,000 lb (approximately 907 kg) supersack available by request. Contact Sorbents Direct for current pricing and availability.

Freight is calculated at checkout using live LTL rates for eligible configurations.

Where Pure-Flo® Supreme 55 Fits

Edible oils & fats: Routine bleaching, polishing and moderate color reduction of compatible vegetable oils and animal fats.
Vegetable-oil refining: Reduction of compatible color bodies and selected polar impurities during bleaching operations.
Specialty oils & ingredients: Clarification of plant-based lipids, waxy fractions and other compatible process oils where finished appearance and stability are important.
Industrial process oils: General clarification and decolorization where practical filtration and treatment economics are priorities.
Multi-oil processing facilities: A broad-use Oil-Dri bleaching-earth option for facilities handling multiple compatible oil types.

Supreme 55 is best viewed as a routine bleaching-earth grade - not a selective pretreatment media.

Its role is most closely associated with general oil purification and moderate color reduction. For targeted treatment of soaps, trace metals or phosphorus-related impurities ahead of downstream processing, compare Pure-Flo® Select 350 and Pure-Flo® Select 450.

Application Guidance

Appropriate bleaching-earth dosage depends on the incoming oil, initial color, contaminant profile, desired finished-oil specification, operating temperature, vacuum, residence time and filtration equipment.

Begin with controlled bench trials using the actual oil or feedstock.
Evaluate multiple dosage rates rather than assuming one universal treatment level.
Measure color reduction, clarity and relevant impurity reduction.
Track filtration rate, differential pressure and cake behavior.
Evaluate oil retention and finished-product yield along with purification performance.
Confirm that treated oil meets downstream process and final-product requirements.

Manufacturer documentation does not establish one universal Supreme 55 dosage for every oil. Final treatment conditions should be established through representative process testing.

Filtration, Yield & Process Economics

Supreme 55 is positioned around practical routine bleaching, so its value should be evaluated using the complete treatment cycle rather than color reduction alone.

Process Variable	Why It Matters
Adsorbent dosage	Controls media consumption and contributes to spent-filter-cake volume.
Color reduction	The clay must deliver the required finished-oil quality without unnecessary over-treatment.
Filtration rate	Influences production throughput and cycle time.
Differential pressure	Excessive pressure buildup can shorten filtration cycles.
Oil retention	Valuable oil retained in the spent clay can reduce process yield.
Spent-earth volume	Affects handling, disposal and overall operating cost.

The strongest bleaching clay is not automatically the lowest-cost bleaching clay.

A grade that achieves the required finished-oil quality at a practical dosage while maintaining filtration throughput and limiting retained product can be economically preferable to a more aggressive adsorbent.

Spent bleaching-earth safety: Bleaching earth that has contacted unsaturated oils can retain significant organic material. Under unfavorable conditions, spent filter cake can self-heat and potentially create a combustion hazard.

Manage spent material according to the current Oil-Dri SDS, process-specific plant procedures and applicable environmental requirements. Avoid handling or storage practices that allow heat to accumulate in spent cake.

When oil is purged from spent filter cake, excessive air exposure may increase oxidation and heat-generation potential. Follow the current Oil-Dri recommendations and site-specific procedures for cake handling, purging, temporary storage and disposal.
