Double Drum Dryer | NutriForge – 02
The Double Drum Dryer NutriForge – 02 dries liquid materials using two rotating, chrome-coated cast iron drums. This Double Drum Dryer scrapes dry product from each drum with a knife, handling steam up to 5.5 bar and temperatures up to 162°C. It processes materials including foodstuffs, chemicals, pharmaceuticals, and pet foods. Required accessories include a mini steam boiler, vapor extraction system, and feed system.
The Double Drum Dryer NutriForge – 02 can be used for product development or instructional purposes, showing students the various uses for drum drying and flaking. This Double Drum Dryer supplies liquid into the space formed by two rotating drums, where a knife scrapes out the dry product. It is delivered fully assembled and prepared for site service hookup.
Product Overview
The device can be used for product development or instructional purposes, ideally showing students the various uses for drum drying and flaking. The machinery is delivered fully assembled and prepared for site service hookup.
The liquid that needs to be dried is supplied into the space formed by the two drums, where it is applied to the rotating drums. On each drum, a knife is used to scrape out the dry product. The stainless steel used in the unit’s construction ensures cleanliness and chemical resistance. In order to assure maximum heat transfer and the capacity to scale up results to production-sized equipment, the drums are made of cast iron and engineering hard chrome coated. The control panel’s electrical inverter controls the shaft-mounted primary drive speed.
A twin-cylinder nip-fed drying machine constructed of cylinder combination endplates and trunnions makes up the Double Drum Dryer. The rolls are capable of handling steam at up to 5.5 bar and have been precisely machined around the circle and internally bored to ensure even heat transfer. The machine’s base plate is attached with circular endplates that house grease-lubricated bearings that support the rolls.

Construction and Design
The Double Drum Dryer NutriForge – 02 is a twin-cylinder nip-fed drying machine constructed of cylinder combination endplates and trunnions. Two drums, each 300mm in diameter and 200mm in length, are made of cast iron and engineering hard chrome coated for maximum heat transfer. The rolls are capable of handling steam at up to 5.5 bar and have been precisely machined around the circle and internally bored to ensure even heat transfer. The machine’s base plate is attached with circular endplates that house grease-lubricated bearings that support the rolls. On each drum, a knife scrapes out the dry product. The unit’s structure is made of rust-free material, and the drum is made of food grade steel. An electrical inverter on the control panel controls the shaft-mounted primary drive speed. The system includes a steam trap and thermally insulated piping.
Required Accessories
- Mini Steam Boiler: the unit is designed to run with steam up to 6 bar of pressure and about 50kg/h steam rate, requiring a boiler to operate. If a boiler is already installed at the customer site, only tubing is needed to connect the system with this unit.
- Vapor Extraction System: fitted above the dryer, draws vapors produced during drying away through the fan and duct assembly.
- Feed System: stainless-steel feed tank and variable-speed pump deliver the material to be dried through the solid pipeline to the dryer feed.
Optional Accessories
- Applicator Roll: gives extra control for materials requiring it
- Dip Tray: positioned under the drum, used to simply apply a film
Scope of Delivery
- 1 Experimental module
- 1 Instruction manual
