Grain sieve
After the grain has been threshed with the flail and the grain straw has
been removed, grains, chaff, clods, short straw, stones and other
impurities remain together. Some of the impurities are removed with the
help of the grain sieve. By shaking the sieve back and forth, the grains
fall through, leaving chaff and short straw behind. The grain sieve is also
used to separate chaff from dust / sand (1). The flax worker also uses a
grain sieve to separate the linseed from the chaff after threshing (see
bruising mail). The grain sieve is a large (diam. 50-100 cm) round sieve
(2) with 2-3 wooden rings (height approx. 10-20 cm) between which a flat
perforated bottom of metal (zinc) or leather (3) is clamped. In the latter
the small round or elongated holes (diam. 1-2 mm; center distance approx. 4
mm) (4) are punched with a punch. The center of the sieve bottom is often
decorated with a figure, a date, initials and / or place name. Sometimes 1,
3 or 4 holes or slots are provided in the edge...
