Cold-pressed juice
Making cold-pressed juice is a two-step process. The first stage is to shred the fruits and vegetables into a pulp. Typically the shredding process uses a steel rotating disc. Produce is loaded into a large hopper feeding tube and typically falls into a filter bag. The second process is the hydraulic press; this exposes the shredded produce to extreme pressures between two plates. The pressure causes the juice and water content from the produce to drip into a collection tray below, leaving behind the fibre content in the filter bag. The fibre left behind is generally composted, recycled in food products or discarded.
John Augustus Just
Extensive testing was done on Just's dried milk to analyze its nutritional value and purity. When compared with other forms of dried milk, the Just Process produced a product that was superior in vitamin and mineral content and solubility, and aided in preventing certain childhood diseases. The company was later bought by the Merrell-Soule Company, which became one of the largest dried-milk companies in the United States. Just sold the rights to his evaporation process to James Robertson Hatmaker, which became known as the "Just-Hatmaker Process".
