Flaxseed shipped to market often contains from 10 to 40 percent dockage and cracked flaxseed, other grains, weed seeds and chaff. These admixtures are mostly undesirable when extracting linseed oil, but they are of value for feed.

In cleaning flax for seed, a 4 X 16 mesh wire sieve or 4 X 14 for large-seeded varieties) will separate the grain and larger seeds from flax. A metal sieve with round holes one-fourteenth of an inch in diameter will remove most of the small weed seeds and fragments of flax seed. The air blast can be regulated to blow out all immature and shrunken flax seed and trash.

Мне кажется, следующие части описания подходят под определение из Гугла: cracked flaxseed, other grains, weed seeds and chaff; immature and shrunken flax seed and trash
