The main difference between the Hurom and Kuvings juicers is that the Hurom has a low speed auger, while the Kuvings has a high speed auger.
The low speed auger of the Hurom juicer grinds fruits and vegetables slowly, which preserves more of the nutrients and enzymes in the juice. The high speed auger of the Kuvings juicer grinds fruits and vegetables quickly, which creates more heat and oxidation. This results in less nutrients and enzymes being preserved in the juice.
