Cold-press juicing produces very little to no heat and preserves all the nutrients in the juice. A cold pressed juicer will first reduce fruit and vegetables into a smooth pulp, then push the pulp through a fine mesh strainer. This ensures higher yield with each use, and also produces a denser, better tasting, more nutritious and healthier juice.
