Tuna oil dosing machine: precise oil dosing that preserves the taste and texture of canned tuna
Piston system with pressure control
Oil is one of the main components of canned tuna: it affects the taste and texture of the meat and makes up a significant share of raw material costs. If the amount of oil varies from can to can, product quality will not be consistent, and overdosing oil at high volumes costs the factory a great deal. The Nano Machine tuna oil dosing machine uses a piston system with precise timing to dose a fixed, set amount of oil into every can.
The machine's pressure control mechanism regulates the oil pressure precisely, so dosing happens without splashing or overflow; no oil is wasted, and the can body and line conveyor stay clean. The machine body is made of 316 and 304 stainless steel, which resists corrosion and contact with food and extends the service life of the machine.
How does a tuna oil dosing machine work?
In a canning line, the tuna oil dosing machine sits after the filler and before the exhaust box and seamer, and it doses all kinds of edible oil, from vegetable oil to olive oil. To learn more, see the olive oil article on Wikipedia.
Setting the oil quantity
The operator sets the amount of oil needed for each can through the machine's control system.
Pressure control
The pressure control mechanism keeps the oil pressure within the optimal range.
Piston dosing
The piston system, with precise timing, doses a fixed volume of oil into every can.
Synchronisation with the line
Dosing is synchronised with the movement of the cans on the conveyor, so no can passes without oil or with too much oil.
Can discharge
The oil-dosed cans move on to the next stage for exhausting and seaming.
Tuna oil dosing machine price
The price of a tuna oil dosing machine depends on the capacity you need, the number of nozzles, the can size and any customisation.

Tuna oil dosing machine technical specifications
The Nano Machine tuna oil dosing machine is built with a capacity of 150 cans per minute, a power rating of 2 kW, dimensions of 2500 × 2000 × 2300 mm and a weight of about 1100 kg. The technical specifications can be customised to suit your line capacity, can size and type of oil.
Less oil waste: direct savings on material costs
In a canning line running at 150 cans per minute, even a few extra millilitres per can add up to hundreds of litres of wasted oil by the end of the month. With precise piston dosing and pressure control, the Nano Machine tuna oil dosing machine keeps the amount of oil exactly in line with the production recipe and eliminates this hidden waste.
Preventing oil splashing and overflow also keeps the can rim clean, which matters for sound seaming and a complete seal, and reduces the risk of leaks and product returns.
For example, in a line that produces tens of thousands of cans of tuna a day, cutting overdosing by just two millilitres per can can save several barrels of oil a month. That is why the accuracy of the tuna oil dosing machine is one of the fastest ways to recover investment in a canning line, and most factories see a noticeable drop in raw material costs within the first months after replacing older methods.
316 and 304 stainless steel: hygiene and durability in contact with food
The parts that come into contact with oil and food are made of 316 and 304 stainless steel, materials used in the food industry for their corrosion resistance and hygiene. This choice ensures the machine's durability in continuous operation, makes washing simple and lowers maintenance costs.
- Precise, even dosing with a piston system and precise timing
- Pressure control mechanism that prevents splashing
- 316 and 304 stainless steel body
- Less oil waste and lower material costs
- Better product taste and texture
- Simple to use and maintain

Applications of the tuna oil dosing machine
The Nano Machine tuna oil dosing machine is used in any line where products are packed in cans with oil, including:
Tuna canned in oil
Dosing vegetable oil or olive oil into cans of tuna and longtail tuna.
Other canned fish
Oil dosing for canned kilka (sprat), sardines and other seafood products.
Canned chicken and ready meals
Adding oil to canned meat products and canned ready meals.
Other food products
Precise oil dosing for food products packed in cans.
Impact on quality and productivity
Precise, even oil dosing keeps the taste and texture of the tuna the same in every can, eliminates oil waste and raises line speed. Combined with low maintenance costs, these benefits lower the cost per can and increase the profitability of the line.
For best maintenance, we recommend cleaning the nozzles and oil path at the end of each shift, regular inspection of the pistons and seals, and checking the dosing volume at the start of each shift. In cold weather, oil temperature also matters, because oil viscosity affects dosing accuracy. The Nano Machine after-sales team covers these points during commissioning, and spare parts are available for up to ten years.
For producers that make both oil-packed and brine-packed canned products, using the Nano Machine oil dosing machine and brine dosing machine together in one line allows fast product changeovers without long stoppages.
Why choose the Nano Machine tuna oil dosing machine?
Nano Machine builds complete canned fish production lines, from the fish cooking blancher and the horizontal tuna filler to the oil dosing machine, brine dosing machine, exhaust box and can washing machine. The tuna oil dosing machine is designed to work in step with this equipment, and its design draws on experience from projects in Iran and exports to Turkey and the Persian Gulf countries.
Summary for production managers
With a precise piston system, pressure control, a stainless steel body and a capacity of 150 cans per minute, the Nano Machine tuna oil dosing machine keeps the amount of oil in every can constant, eliminates waste and ensures the quality of your canned tuna.
