Description

Searching for a cold press oil expeller machine manufacturer and supplier in Delhi, India? Our cold press oil expeller is designed for producers who prioritise oil quality, nutritional retention, and premium market positioning over sheer extraction volume. Cold press extraction means the oilseeds are pressed at temperatures that do not exceed 40 to 60 degrees Celsius, which preserves the natural flavour, aroma, colour, and heat-sensitive nutrients such as antioxidants, essential fatty acids, and vitamins that are destroyed during conventional hot pressing. This machine is the foundation of the growing cold-pressed oil segment in India, where health-conscious consumers are willing to pay a premium for oils that are as close to their natural state as possible. Manufactured at our Nangloi, Delhi factory, this expeller combines the low-temperature pressing capability with reliable construction and practical design for daily commercial use.

What is a cold press oil expeller machine? A cold press oil expeller is an oil extraction machine that crushes oilseeds using purely mechanical force at temperatures maintained below 60 degrees Celsius throughout the pressing process. Unlike conventional expellers where friction generates significant heat that can raise oil temperature above 100 degrees Celsius, a cold press machine uses a slower screw speed, a barrel design that minimises friction heat, and sometimes an external cooling system to keep the oil temperature low. The result is an oil that retains its natural colour, nutty flavour, and nutritional profile, which is why cold-pressed oils command premium prices in the Indian market, particularly for oils like groundnut, sesame, coconut, and mustard.

Key Features and Build Quality. The barrel is constructed with a cooling jacket through which ambient-temperature water circulates to absorb friction heat and keep the pressing zone below the critical temperature threshold. The screw operates at a lower RPM compared to hot press expellers, which reduces the rate of heat generation while still providing sufficient pressing force for effective extraction. The screw profile is specifically designed for cold press operation, with a gentler compression ratio that extracts oil gradually without the aggressive friction of a conventional screw. The barrel drainage slots are wider than on hot press models because cold-pressed oil is more viscous and needs larger openings to flow out freely. All oil-contact components are made from AISI 304 food-grade stainless steel to ensure purity and prevent any metallic taste from contaminating the oil. A digital temperature display mounted on the control panel shows the real-time oil temperature at the barrel outlet, allowing the operator to verify that the cold press threshold is being maintained. The machine frame is fabricated from welded steel with a powder-coated finish for durability in the production environment.

How does the cold press oil expeller machine work? Seeds are loaded into the hopper and fed into the pressing chamber by the rotating screw. As the seeds move through the barrel, they are compressed between the screw flights and the barrel wall. Oil is squeezed out through the drainage slots and collected in the tray below. The critical difference from a hot press expeller is that the cooling water circulating through the barrel jacket absorbs the heat generated by friction, keeping the oil temperature low. The operator monitors the temperature display and adjusts the feed rate or cooling water flow if the temperature begins to approach the upper limit. The de-oiled cake exits from the discharge end, and because the pressing was done at low temperature, this cake retains more of its natural nutrients and can be used as a high-value animal feed ingredient or even as a flour ingredient in some applications. The extracted oil flows through the collection tray into a filtration unit that removes fine particles without requiring heat-intensive refining, preserving the cold-pressed characteristics of the final product.

Technical Specifications. Our cold press oil expeller has a processing capacity of 10 to 25 kilograms per hour, which is intentionally lower than a hot press expeller of comparable size because the slower screw speed and gentler pressing action extract oil over a longer pressing duration. The motor is 5 HP, three-phase, 415V, 50 Hz, driving the screw through a gearbox that reduces speed to 18 to 25 RPM. The screw diameter is 60 mm with an effective pressing length of 480 mm. The barrel includes an integrated cooling jacket with inlet and outlet connections for a recirculating water system. The cooling system requires a small water pump, which is included in our standard package. The machine dimensions are approximately 1300 mm by 550 mm by 950 mm. Weight is around 280 kilograms. The temperature display reads from 0 to 150 degrees Celsius with a resolution of 1 degree. An optional chiller unit can be supplied for operations in hot climates where ambient water temperature is too high to maintain the cold press threshold.

Applications and Industries. This machine is used by cold-pressed oil brands that sell directly to consumers through retail outlets and online platforms, by organic oil producers who need to maintain cold-press certification, by health food companies that use cold-pressed oils as ingredients, by traditional oil mills that want to offer kachi ghani and cold-pressed options alongside conventional oils, and by gourmet food producers who value flavour and aroma in their oils. The machine is also popular among food entrepreneurs who sell cold-pressed groundnut oil, sesame oil, coconut oil, and mustard oil at farmer's markets and specialty stores, where the cold-pressed process is a key selling point.

Benefits of Choosing Our Cold Press Oil Expeller. The nutritional superiority of cold-pressed oil is the primary benefit, with studies showing that cold-pressed oils retain significantly more vitamin E, polyphenols, and unsaturated fatty acids compared to hot-pressed oils. The flavour and aroma are noticeably better, which is why cold-pressed oil tastes more like the seed or nut it came from. The premium pricing that cold-pressed oil commands in the market means you can achieve higher profit margins per litre even though the extraction rate per kilogram of seed is slightly lower than hot pressing. The cooling jacket system is simple to operate and does not add complexity to the machine. The stainless steel construction ensures that the oil meets food safety standards and maintains its purity from press to bottle.

Maintenance and Care. Flush the cooling jacket with clean water at the end of each production day to prevent mineral buildup in the water passages. Inspect the cooling water hoses monthly for leaks or cracks and replace them as needed. The screw and barrel should be inspected every 150 hours for wear, though the lower pressing speed means they last longer than in hot press applications. Clean the oil collection tray and filter after every shift. Lubricate the main bearings weekly with food-safe grease to prevent any lubricant from contaminating the oil. The temperature sensor should be calibrated periodically using a reference thermometer to ensure accuracy. Drain and replace the gearbox oil every 500 hours of operation. Store the machine in a clean environment and cover the hopper when not in use to keep out dust and insects.

Frequently Asked Questions. What is the price of a cold press oil expeller machine? Cold press models carry a premium over standard expellers due to the cooling system and food-grade stainless steel construction. Contact us for a detailed quote based on your capacity and oil type requirements. What is the maximum oil temperature during pressing? Our machine keeps the oil below 60 degrees Celsius under normal operating conditions, and the temperature display lets you verify this in real time. Is the extraction rate lower than hot pressing? Yes, typically 5 to 10 percent lower, but the premium price of cold-pressed oil more than compensates for the difference in most markets. Can I use this machine for coconut oil? Absolutely. Cold-pressed coconut oil is one of the highest-value products in this category and our machine handles copra and fresh coconut meat effectively.
