Fresh-pressed oil leaves the press hot — and hot oil darkens, loses aroma and ages fast. Cooling machines bring 50 kg charges from 100°C to 60°C in 8–25 minutes; the 500 kg stainless cooling tower chills full production batches for low-temperature filtering, so you can press today and sell bright, premium oil tomorrow.
Heat is the enemy of finished oil: every hour spent hot costs color, flavor and shelf life, and warm oil cannot be fine-filtered — waxes and fats stay dissolved, only to cloud later in the bottle. Controlled rapid cooling locks in quality and prepares the oil for low-temperature filtration in one step.
Three options match mill size: the air-cooled unit handles 50 kg charges in 15–25 minutes; the triple-cooling unit does the same charge in about 8 minutes; the 500 kg cooling tower with built-in refrigeration chills a full day's pressing for the press-today-sell-tomorrow workflow.
| Model | Charge | 100→60°C Time | Size |
|---|---|---|---|
| Air-cooled unit | 50 kg | 15–25 min | 58×58×120 cm |
| Triple-cooling unit | 50 kg | ≈8 min | 100×70×110 cm |
| Cooling tower | 500 kg | batch chilling | with built-in cooling unit |
Purpose-built heat exchange brings oil to filtering temperature in minutes — not the hours of open-air cooling.
Rapid cooling halts the darkening and aroma loss that hot storage causes; oil reaches the shelf brighter.
Output temperature is matched to cold filtering, so cooled oil flows straight to the filter line.
All oil-contact surfaces stainless steel; simple to clean between oil types.
From 50 kg workshop units to the 500 kg tower for full production batches.
Ambient cooling takes hours, during which hot oil oxidizes, darkens and loses aroma — and open vessels collect dust and moisture. Machine cooling does the job in minutes inside closed stainless steel.
Properly cooled, filtered and stored oil keeps its color and flavor for months. The biggest single factor is how fast it got from press temperature down to storage temperature — which is exactly what this machine controls.
Filtering oil after it has been chilled, so waxes and high-melting fats have already crystallized and are removed by the filter instead of clouding the bottle later. Cooling capacity is the prerequisite.
Match your daily output: 50 kg units suit workshops pressing a few hundred kg per day; the 500 kg tower suits mills running a 125 or 140 press at full shift.
No oil is lost in cooling — it is a closed heat-exchange process. What you gain is sellable quality: clearer color, better aroma and longer shelf life at the same volume.
