Description

Searching for a mustard oil expeller machine manufacturer and supplier in Delhi, India? Our dedicated mustard oil expeller is engineered specifically for the unique properties of mustard seeds, which are smaller, harder, and oilier than many other oilseeds. Mustard oil production demands a machine that can handle high oil content, fine seed size, and the pungent volatile compounds that define the flavour and aroma of genuine mustard oil. Generic oil expellers often struggle with mustard seeds, producing low oil yield, excessive residue in the cake, or inconsistent extraction. Our machine solves these problems with purpose-built components designed for mustard seed processing. Every unit is manufactured at our Nangloi, Delhi factory with attention to the specific requirements of mustard oil producers.

What is a mustard oil expeller machine? A mustard oil expeller machine is a mechanical screw press designed to extract oil from mustard seeds by crushing them under high pressure between a rotating screw and a stationary barrel. As the screw pushes the seeds through a narrowing cavity, the oil is squeezed out through small openings in the barrel and collected below, while the crushed, de-oiled cake exits from the far end. This cold or warm pressing process preserves the natural pungency, colour, and nutritional value of mustard oil without the use of chemicals, which is exactly what consumers who buy pure mustard oil expect.

Key Features and Build Quality. The barrel and screw are made from case-hardened alloy steel that resists the abrasive wear caused by the hard mustard seed hulls. The screw has a special profile with varying pitch and depth zones that progressively compress the seeds, first cracking them, then squeezing the oil, and finally compacting the cake for clean discharge. The barrel is perforated with precision-drilled oil drainage slots that are sized specifically for mustard seed particles, preventing fine cake material from passing through with the oil. A heavy-duty gearbox with hardened gears transmits power from the motor to the screw shaft, and the entire assembly sits on a welded steel frame with anti-vibration mounts. The hopper has a magnetic separator built into its throat to catch any tramp metal before it enters the pressing chamber, protecting the screw and barrel from damage. A temperature control option allows you to gently warm the seeds to 40 to 60 degrees Celsius before pressing, which improves oil flow and yield without reaching temperatures that would degrade the oil quality.

How does the mustard oil expeller machine work? Clean mustard seeds, ideally dried to 6 to 8 percent moisture content, are fed into the hopper. The rotating screw draws the seeds into the pressing chamber and begins moving them forward. As the screw pitch decreases along the barrel length, the space available for the seeds shrinks, and pressure builds. The seeds are crushed, and the oil is forced out through the barrel drainage slots. The oil drips into a collection tray below and flows through a filter screen into a holding tank. Meanwhile, the de-oiled cake, now compressed into hard flakes or pellets, emerges from the nozzle at the end of the barrel. The nozzle diameter and spring tension can be adjusted to control how much pressure is applied and how dry the cake comes out. For mustard oil, a moderate pressure setting with a slightly open nozzle produces the best balance between oil yield and cake quality. A single pass extracts roughly 85 to 90 percent of the oil content from the seeds, and the remaining oil stays in the cake, which is then sold as cattle feed or used in other applications.

Technical Specifications. Our standard mustard oil expeller has a processing capacity of 20 to 30 kilograms per hour of mustard seeds. The motor is 7.5 HP, three-phase, 415V, 50 Hz. The screw diameter is 60 mm with a working length of 500 mm. The barrel is 600 mm long with replaceable liner sections in the high-wear zones. The gearbox ratio is 15:1, providing high torque at low screw speed for efficient pressing without excessive friction heat. The oil collection pan is made from stainless steel and includes a removable mesh filter. The machine footprint is approximately 1400 mm by 500 mm by 900 mm. Weight is around 350 kilograms. An optional pre-heater attachment can be fitted to warm the seeds before they enter the pressing chamber, and this is recommended for winter operation or when pressing cold seeds straight from storage.

Applications and Industries. This machine serves mustard oil mills in North India, Punjab, Haryana, Rajasthan, and UP where mustard is a primary oilseed crop. It is used by cold-press oil producers who market premium kachi ghani mustard oil, by oil extraction units that supply refined mustard oil to packaging companies, by rural oil mills operated by cooperatives and self-help groups, and by food manufacturers who use mustard oil as an ingredient in pickles, marinades, and processed foods. The cake by-product is valuable as animal feed, so the machine serves a dual economic purpose.

Benefits of Choosing Our Mustard Oil Expeller. The dedicated design for mustard seeds means you get higher oil yield compared to a general-purpose expeller. The oil comes out clean with minimal suspended solids, reducing the load on your downstream filtration equipment. The pungent flavour compounds in mustard oil are preserved because the machine operates at controlled temperatures, which is a major selling point for consumers who want authentic mustard oil. The robust construction handles the abrasive nature of mustard seed hulls without frequent breakdowns. The adjustable nozzle lets you fine-tune the pressing parameters for different mustard varieties such as yellow mustard, brown mustard, or toriya, each of which has slightly different oil content and seed hardness.

Maintenance and Care. Drain the gear oil after the first 100 hours of operation and replace it, then change it every 500 hours thereafter. Inspect the screw and barrel liners every 200 hours for wear, especially if you are pressing large volumes, and replace them when the oil yield drops noticeably. Clean the barrel drainage slots regularly using the provided cleaning pins to prevent clogging. Lubricate the main bearings every week with a lithium-based grease. Check the belt tension if your model uses a belt drive, and adjust or replace as needed. Keep the collection pan and filter screen clean to maintain oil quality and prevent rancidity from residue buildup.

Frequently Asked Questions. What is the price of a mustard oil expeller machine? Pricing varies with capacity, motor size, and optional accessories like the pre-heater. Contact us for a detailed quotation. What is the oil recovery rate? You can expect 85 to 90 percent extraction in a single pass. Can this machine press other oilseeds? It can press rapeseed and similar small seeds effectively, but for larger seeds like mustard is specifically optimised. Is cold pressing possible? Yes, the machine operates without the pre-heater for cold press production, yielding raw kachi ghani oil. Do you offer a complete oil mill setup? Yes, we supply the expeller, filter machine, storage tanks, and bottling equipment as a complete turnkey solution.
