Gears for food processing equipment

KHK Gears manufactures a variety of standard gears suitable for use in food processing machines.

In most food processing machines, water resistance and rust prevention are required due to the nature of the equipment and hygiene of the food itself.
For sanitary machines in particular, there is a requirement for high heat resistance, due to steam sterilization after a high temperature cleaning.
In general, since the processing target of the machine is food which requires a high degree of safety, the machine itself is required to be suitable for hygienic environments such as clean rooms.

For food agitators and the like, it is likely that there is a change in physical property (for example, a change from liquid to paste) at the start and end of the stirring process.
In that case, since the viscosity of the food changes during stirring, a change in the torque is required, and it requires a mechanical design that accounts for these changes in advance.

An application example of KHK standard gears in the food processing equipment industry

TOPACK Ultra-high-speed Three-way Seal Bag Filling and Packaging Machine R

Machine Application
- A top-level automatic filling and packaging machine
- Makes and fills bags at ultra-high speeds of 300 to 800 bags per minute

Features
Ultra-high-speed filling and packaging is achieved by the use of rotary methods that make, fill and seal bags in the horizontal direction.
In addition, the filling time can be extended to reduce the occurrence of biting into the seal, and the sealing time can be extended to achieving stable seal strength.
Also, by combining with an integration device, the unit can be connected to carton making machines, horizontal pillow machines, banding machines, bag-feeding packaging machines, etc.

Gears Used
MM, SM and SMB miters change the motion from the horizontal-shaft drive to the vertical-shaft drive, which is then transmitted to the filling device, and combined with SW worms and CG worm wheels to be used for adjusting the timing of filling while operating the filling device.
