In 1966, Dr. Ann Wigmore, founder of the Hippocrates Health Institute in Boston, commissioned Sundance Industries to design an efficient wheatgrass juicer. Since then they have been designing and manufacturing many variations of the Original Wheateena Wheatgrass Juicers. The Wheateena line of wheatgrass juicers are manufactured 100% in the USA. Their juicers are sturdy, efficient and reliable. Service and reliability is their motto. Product Details Used extensively in juice bars. Continuous pulp expulsion. Juicing speed: 2 1/2 ounces per minute for most grain grasses, leafy greens, herbs and sprouts.
