The noise and vibration cause was. Due to the low height of the paddles.The non-metal paddles are shaped similar to an aircraft propeller and have difficulty in pushing the larger ice cubes onto the shaving blade as the ice cubes tend to go back over these paddles, instead of being pushed onto the shaving blade. The larger the ice cube, the noisier the shavers became, when large 30x50mm size ice cubes were tried, the units tested, other than the KC-500 failed.
It was found that the wattage of the drive motor depicts the size of the ice cubes that can be processed with this type of unit, that uses a non-metal internal rotor paddle. HC-500 220-240v 500 Watt motor. This particular unit worked smoothly, due purely to the 500-Watt motor, it shaved ice cubes up to 30x50mm quickly, with little effort and shaved any sized ice cube much faster than any other unit tested.
It always produced a pretty consistent type of shaved ice when using the adjuster for the type & size required and after testing is now currently working successfully in a medium sized venue. Without doubt this unit is the best of the bunch of any other similar unit that use these non-metal paddles. With a great saving in staff time and cost using manual shavers. KCICL is a UK supplier.
