Unprocessed, quinoa is inedible because of the bitter-tasting saponins on its seed coat for protection against pests. Classical industrial plants use water for removing saponins. By repeated washing of the quinoa, the saponins are removed.
SCHULE Mühlenbau has developed a process in which the saponins are removed without the use of water. This process has already been successfully put into practice in South America.
The following overview shows machines which are used for the processing of quinoa. Here, you can find more information about various SCHULE machines.
