Fish cooking blancher: even, safe cooking with controlled steam
Trolley-loaded design with a space-saving vertical door
Precooking fish (blanching) before cleaning and can filling is one of the key stages in canned tuna production. If cooking is uneven, some fish stay undercooked while others are overcooked; the result is lower meat quality, harder separation of skin and bones, and more waste. The Nano Machine fish cooking blancher uses controlled steam cooking to make this stage even, safe and repeatable.
In this machine, operators easily guide trolleys carrying trays of portioned fish into the blancher with the help of stainless steel guide rollers. The space-saving vertical door then closes automatically, and smart steam valves feed steam into the chamber precisely and under control, so every piece of fish is cooked under the same conditions.
How does a fish cooking blancher work?
Cooking in this machine is done with steam, which transfers heat quickly and evenly to every surface of the fish. To learn more, see the steam article on Wikipedia.
Loading the trolleys
The operator pushes trolleys carrying trays of portioned fish into the machine with the help of the stainless steel guide rollers.
Closing the vertical door
The space-saving vertical door closes and locks automatically.
Controlled steam inlet
The smart steam valves open and steam enters the chamber precisely.
Even cooking of the fish
The fish are cooked evenly at the set temperature and time, while the safety valves keep the pressure safe.
Unloading the trolleys
At the end of the cycle the door opens and the trolleys are taken out for cooling and cleaning of the fish.
Fish cooking blancher price

Fish cooking blancher technical specifications
The Nano Machine fish cooking blancher is built with a capacity of 1000 kg per cycle, dimensions of 3200 × 1800 × 3500 mm and a weight of about 1300 kg. The capacity, number of trolleys and steam system can be customised to suit your daily production volume and fish type.
Safety in steam cooking: safety valves and door lock
Working with steam demands a high level of safety. The Nano Machine fish cooking blancher is equipped with safety valves and a vertical door locking system: the safety valves prevent excessive pressure build-up, and the door lock stops the door from opening during cooking. This design protects operators and keeps the cooking process stable.
The smart steam valves feed steam into the machine precisely and under control, so steam consumption is optimised and the chamber temperature stays constant throughout the cycle. The result is even cooking on every tray and lower energy use.
Space-saving vertical door and stainless steel rollers: easier work in the hall
Ordinary hinged doors take up a lot of space in front of the machine and get in the way of trolley traffic. Instead of swinging forward, the space-saving vertical door moves upward, so it needs less room and makes access to the machine easier. The stainless steel guide rollers keep the trolleys moving smoothly and prevent them from hitting the body and damaging the machine or the product.

Applications of the fish cooking blancher
The Nano Machine fish cooking blancher is used in any plant that cooks portioned fish before processing or packaging, including:
Canned tuna factories
Precooking tuna and longtail tuna before cleaning, meat separation and can filling.
Ready-made seafood production
Even cooking of fish for ready meals, frozen foods and semi-prepared products.
Industrial kitchens
Preparing large volumes of cooked fish with consistent quality in a short time.
Secondary processing industries
Processing fish into by-products and raw materials for the food industry.
How the fish cooking blancher improves quality and productivity
Even, controlled cooking preserves the colour, texture and flavour of the fish and makes it easier to separate skin and bones during cleaning, which means a higher yield of usable meat and less waste. The machine's fast, efficient operation shortens process time, and correct, timely cooking extends the shelf life of the finished product.
For best maintenance, we recommend regular inspection of the safety valves and steam valves, checking the door seal, and cleaning the chamber and rollers after every shift. During commissioning, the Nano Machine after-sales team trains operators on the optimal cooking time and temperature for your fish type and on the maintenance schedule.
Cooking time and temperature depend on the fish species, the size of the pieces and their fat content; larger fish or thicker pieces need more time. Recording the settings that work for each fish type and loading the trays evenly ensures that every cycle of the fish cooking blancher gives the same result. Arranging the pieces in a single layer on the trays, without overlapping, also helps steam penetrate evenly and keeps the centre of the pieces from staying undercooked.
Why choose the Nano Machine fish cooking blancher?
Nano Machine builds complete canned fish production lines, from the fish cooking blancher to tuna fillers, the tuna oil dosing machine, the brine dosing machine and the exhaust box. The fish cooking blancher 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
The quality of canned tuna is shaped at the precooking stage. With a capacity of 1000 kg per cycle, even steam cooking, a high level of safety and a space-saving design, the Nano Machine fish cooking blancher preserves meat quality, reduces waste and raises the productivity of your line.
