Method and System for Producing Gluten-Free Oats

摘要

A method and system for removing foreign grains from oat grains to establish gluten-free oats, i.e., oat grains having gluten levels below 20 ppm and, more preferably, below 10 ppm, relies upon performing various mechanical differentiation operations on a combination of grains, including oats and foreign, or gluten containing, grains. The mechanical differentiation operations can be arranged in series or in a combination of series and parallel operations. The various operations preferably include width grading and multiple length grading steps, as well as an aspirating steps, as well as a potential debearding step. The resulting oats can be used to make a wide range of gluten-free oat food products, including cereal and granola products.

主权项

1. A method of producing gluten-free oats from a combination of grains including oats and other, gluten containing grains comprising:
performing a first series of mechanical operations, including at least one width grading operation, on the combination of grains to establish at least first and second blends of grains; performing a second series of mechanical grading operations, including at least one length grading operation, on the first blend of grains to establish a first supply of processed grains; and performing a third series of mechanical grading operations, including at least one length grading operation, on the second blend of grains to establish a second supply of processed grains, with the third series of mechanical grading operations being distinct from and performed in parallel with the second series of mechanical grading operations.
