Frying Oil Purification & Complete Filtration Systems: Extending Oil Life, Cutting Costs, Improving Quality
Created on 08.26
Introduction: Extending Oil Life, Reducing Cost, Improving Quality
In food processing, frying oil is one of the most significant operating costs. As oil is repeatedly heated, it undergoes chemical degradation — free fatty acids increase, peroxides form, color darkens, and harmful compounds accumulate. The result is shorter oil life, higher replacement costs, and potential food safety concerns.
The global frying oil filter machine market is growing steadily, valued at approximately USD 124 million in 2024 and projected to reach USD 164 million by 2031, at a CAGR of 4.2%. The broader cooking oil filter market is even larger, estimated at USD 2.18 billion in 2025 and projected to reach USD 4.48 billion by 2033, growing at a CAGR of 9.4%.
Dongying Jusen Chemical is pleased to announce that we now supply frying oil purification and complete filtration systems through our equipment manufacturing partners — expanding our equipment portfolio alongside our existing silica gel and oilfield chemical product lines.
Part I: About Our Equipment Manufacturing Partners
1. Who We Work With
Our frying oil purification equipment is manufactured by a specialized environmental equipment company based in Shandong Province, China. The company focuses on the design, production, installation, and commissioning of energy-saving and environmental protection equipment, with a core focus on:
- Frying oil purification systems
- Edible oil refining complete solutions and equipment
- Automatic slag-discharging refining centrifuges
- Centrifugal and axial flow fans
- Electrostatic field cleaning machines
- Oil fume purifiers
Our partner holds national invention patents for its frying oil purification technology, including a patented "Frying Oil Purification Treatment Device." The equipment is designed to extend frying oil service life, reduce operating costs, and improve food quality and safety.
Part II: Key Product — Frying Oil Purification System
1. The Problem: Frying Oil Degradation
In commercial frying operations — from restaurants and fast-food chains to industrial snack production — frying oil degrades through a combination of hydrolysis, oxidation, and polymerization. The consequences are well documented:
- Acid value (AV) increases
— indicating the accumulation of free fatty acids
- Peroxide value (POV) increases
— signaling oxidative rancidity
- Color darkens
— from golden to dark brown
- Off-flavors develop
— affecting product taste and aroma
- Harmful compounds form
— including polar compounds and polymers
Without effective treatment, oil must be replaced frequently, driving up costs and generating waste oil disposal expenses.
2. Patented Purification Technology
Our frying oil purification system uses a multi-stage physical and chemical treatment process to remove degradation products from used frying oil. The system integrates:
Stage 1: Pre-treatment & Filtration
Hot oil is drawn from the fryer and passes through a pre-pressurized filter that captures large particles, food debris, and suspended solids. The pre-filter protects downstream components and improves overall system efficiency.
Stage 2: Chemical Treatment & Separation
The oil is treated with food-grade purification agents in a series of reaction vessels. A patented four-phase separator efficiently separates oil, water, sludge, and treatment agents. This step neutralizes free fatty acids and reduces peroxide compounds.
Stage 3: Decolorization & Fine Filtration
The oil passes through a single-layer multi-cycle filtration decolorization unit. This design reduces internal pressure on the machine, achieving better filtration results and extending the overall service life of the equipment.
Stage 4: Final Polishing
The purified oil is returned to the fryer or storage tank, ready for continued use with significantly improved quality parameters.
3. Performance Data
Laboratory testing provides clear performance data for the purification system. Using palm oil repeatedly fried with batter cakes, the following results were recorded:
Parameter | Before Purification | After Purification | Reduction |
Acid value (KOH), mg/g | 12.3 | 0.3 | 97.6% |
Peroxide value, mg/g | 0.52 | 0.04 | 92.3% |
Cost efficiency: Operating cost for the purification process is approximately 200 RMB per ton of oil. With an efficiency of 90%, one ton of used oil generates 10.8 tons of qualified oil — a return that far exceeds the treatment cost.
These results demonstrate that the purification system can restore heavily degraded frying oil to near-fresh quality, dramatically extending oil life and reducing replacement frequency.
Part III: Key Product — Complete Filtration & Purification Systems
Beyond frying oil purification, we supply complete filtration and purification systems for edible oil processing and industrial applications.
1. Edible Oil Refining Complete Solutions
We provide turnkey edible oil refining equipment covering degumming, deacidification, decolorization, and deodorization processes. These systems are suitable for:
- Vegetable oil processing (soybean, rapeseed, peanut, sunflower, palm)
- Used cooking oil regeneration
- Biodiesel feedstock pretreatment
2. Automatic Slag-Discharging Centrifuges
The automatic slag-discharging refining centrifuge is a core component of the purification systems. It provides continuous separation of solids from liquids, enabling:
- Uninterrupted operation without manual cleaning
- Consistent separation efficiency
- Reduced labor requirements
- Longer equipment life
3. Integrated Filtration Systems
We design and supply integrated filtration systems that combine multiple treatment stages into a single coordinated unit. These systems are engineered to meet specific customer requirements for throughput, filtration precision, and target oil quality.
Filtration precision: Our systems can achieve filtration down to 5 microns, effectively removing fine particles, carbonized material, and suspended impurities from frying oil.
Part IV: How Equipment and Chemicals Work Together
Our frying oil purification equipment pairs naturally with our existing product lines:
Treatment Stage | Equipment | Chemical |
Pre-filtration | Pre-pressurized filter | Filter material cleaning agent |
Chemical treatment | Reaction vessels, four-phase separator | Food-grade purification agents |
Decolorization | Multi-cycle filtration decolorization unit | Silica gel sand (for industrial oil decolorization) |

Part VI: Market Context — Why Frying Oil Purification Matters
1. Regulatory Pressure
Food safety regulations worldwide are tightening restrictions on frying oil quality. In China, GB 2716-2018 (National Food Safety Standard for Vegetable Oils) sets limits on acid value, peroxide value, and polar compounds in frying oil. Similar regulations exist in the EU, US, and other major markets.
2. Cost Pressure
Edible oil prices have experienced significant volatility in recent years. For food processing operations that consume tons of oil daily, extending oil life by even 20–30% translates into substantial annual savings. Our purification system, with an operating cost of approximately 200 RMB per ton, offers a compelling return on investment.
3. Sustainability
Waste frying oil disposal is an environmental burden. By extending oil life and recovering used oil, purification systems reduce waste generation and support circular economy objectives.
