Round Bucket Frying Cooking Oil Filter Purifier Machine Stainless Steel is an integrated oil purification equipment designed for small and medium-sized fryers and oil pans. The cooking oil filter machine effectively removes residues in the oil through vacuum pre-extraction and five-stage filtration to prevent the oil from becoming sour and breeding harmful substances. The machine body and the oil receiving bucket are made of high temperature resistant and corrosion-resistant food-grade 304 acciaio inossidabile, which meets international health and safety standards.

In commercial kitchens and catering chains, Round Bucket Frying Cooking Oil Filter Purifier Machine Stainless Steel achieves continuous removal of bread crumbs, carbonized particles and tiny suspended matter in the oil through an efficient five-stage filtration system and vacuum alarm function, thereby greatly extending the service life of the oil and maintaining the consistency of food taste. The equipment uses 100% SUS304 food grade stainless steel mesh screen, which is resistant to high temperature and corrosion, easy to clean and durable. It not only integrates vacuum suction and automatic circulation to ensure the stable operation of the cooking oil filter machine under high load environment, but also can be moved by casters or fixed installation to flexibly meet the needs of different kitchen spaces.

Macchina per filtro dell'olio da cucina per parametri tecnici friggibili

The Round Bucket Frying Cooking Oil Filter Purifier Machine operates by drawing hot cooking oil from the fryer into a sealed filtration unit, passing it through multi-stage filter elements to remove coarse and fine particulates, then using a vacuum chamber to dehydrate and de-gas the oil, and finally recirculating purified oil back to the fryer—under full PLC control to ensure continuous, efficient operation.

1. Oil Suction and Intake
The machine’s oil pump creates suction to draw used oil from the fryer into the filter unit .Some models employ a positive-displacement or gear pump to maintain steady flow regardless of oil viscosity variations.

2. Multi-Stage Filtration
2.1 Coarse (Surface) Filtration
First, oil passes through a coarse mesh or metal screen that captures large crumbs and carbonized debris (>200 µm)

2.2 Fine (Depth) Filtration
Prossimo, oil flows through depth-filter cartridges—often cellulose or fabric layers—that trap smaller solids (10–100 µm) within the filter medium’s thickness

2.3 Specialty Media (Adsorption / Emulsion Breaking)
In advanced units, activated carbon or molecular sieve beds remove free fatty acids, color bodies, and emulsified water, improving oil clarity and stability

3. Vacuum Dehydration & Degassing
The partially filtered oil enters a vacuum chamber where system pressure is reduced to around –0.06 MPa, lowering water’s boiling point to facilitate rapid moisture evaporation .Under vacuum, dissolved gases (oxygen, CO₂) also evolve out of solution, reducing oxidative degradation pathways in the oil .

4. Pressure-Driven Flow Through Filter Media
A controlled pressure differential (up to 0.4 MPa) across filter elements forces oil through pore structures, ensuring fine particulates remain on the upstream side while clean oil exits downstream.

5. Continuous Recirculation
Once dehydrated and de-gassed, the purified oil is pumped back into the fryer vessel, establishing a closed-loop circulation that maintains oil quality during prolonged frying operations .

6. Control System & Safety Features
Built-in sensors monitor vacuum level, oil temperature, and differential pressure across filters; automated alarms or shutdowns occur if thresholds are exceeded to prevent filter overload or pump cavitation .Many units use PLC logic to sequence valve actuation, pump speed, and heater elements, enabling one-button operation and remote diagnostics

Through this combination of suction, staged particulate removal, vacuum dehydration, and pressure-driven flow—under automated control—the Round Bucket Frying Cooking Oil Filter Purifier Machine delivers continuous, high-efficiency oil purification, extending oil life, improving food quality, and reducing operating costs.

Facile da pulire, no oil residue, no blockage;

Use positive pressure to maximize filtration efficiency;

The oil after air pressure filtration is clear and pure, which prolongs the service life of frying oil and saves production costs;

Improve food quality: stabilize oil temperature and cleanliness, so that fried food has golden color and crispy taste;

Extend the use cycle of oil: remove tiny particles, greatly reduce the speed of oil rancidity, and reduce the frequency of replacement;

Reduce operating costs: save procurement costs and waste oil treatment costs through continuous filtration and recycling of oil;

Come sappiamo, il processo di produzione alimentare richiederà molto tempo per friggere l'olio , e la qualità diminuirà gradualmente. i prodotti fritti appaiono neri, l'odore dell'olio, alto contenuto di olio, il valore di acidità e il valore di perossido vengono superati, fumo e così via. Influiscono notevolmente sulla percezione del cibo da parte del cliente. E portano anche problemi di igiene e sicurezza alimentare. Perciò, l'olio di frittura deve essere sostituito dopo un periodo di utilizzo, Tuttavia, spesso la sostituzione dell'olio di frittura comporta un aumento dei costi di produzione. L'uso delle apparecchiature di filtraggio dell'olio di frittura HFD sarà in grado di risolvere i problemi di cui sopra. La macchina per il filtro dell'olio per frittura può prolungare la durata dell'olio, risparmiando sul costo del petrolio.
