Air-powered kebab skewer

MiVEG semi-automatic kebab skewers can hygienically produce more than 4000 kebabs/h. German beech wood can be used to pierce poultry, vegetables, cheese or meat and the final result still looks like a homemade product.

Deprag, a complete service provider for air motors, offers not only the motors but also a specially designed solution for each particular application.

Mini party skewers loaded with between 20 g and a quarter of a kilo worth of food can therefore be cost-effectively produced.

The wooden skewers can be from 10 up to 25 cm long. Within a few minutes the machine can be converted to other products because the cartridge can remove the skewers individually, which means low wear and easily changeable parts. Therefore, shorter conversion time is achieved and robust construction design for durability is provided.

The heavy work of the machine is done by the turning of the skewer unit which is powered by two air vane motors. In this unit the skewer is driven over two belts through the pieces of meat, onion and peppers.

The Deprag air motor drives are made from stainless steel and the robust and sealed design of the drives makes them suitable for applications in moisture-prone conditions and able to withstand cleaning with aggressive cleaning agents, such as those used in the food processing industry.

Deprag stainless steel motors’ range of performance is between 20 W and 1.2 kW as standard design in a speed range of up to 24,000 revolutions/min. In special application cases such as in the food processing industry, oil-free operation when dry running is possible. The air motors put air under pressure and use the energy produced to drive the rotors in the tools. Vane motors consist essentially of a rotor which revolves in an eccentrically offset perforation of the rotor cylinder. Because of this eccentrically offset perforation, the vanes form working chambers, the volume of which increases in the turn direction. In operation the centrifugal force of the vanes puts pressure on the wall of the cylinder and seals off the working chambers from each other. The pressure energy which develops is converted into kinetic energy. Through operation with air power the vane motors are overload safe and may be loaded to full standstill.

In addition, the air motor is temperature insensitive and cool in comparison to other drive systems under increased strain.
