The hardness of the wheat and the constitution
of the endosperm requires to choose the correct
sieve fabrics. A decision has to be made between
high sifting efficiency and long lifetime .

2.1.1 Humidity infuence on Polyamide fabrics
Polyamide absorbs up to 4.4%
humidity
We can use this capacity, to achieve
more tension
or
compensation if the humidity changes
![Page 20: SEFAR Solutions for Flourmills - IAOM MEA · 2. SEFAR - Solutions for Flourmills 1. Introduction 2. SEFAR-Solutions for Flourmills 2.1 Sifters 2.2 Purifiers 2.3 Centrifugal sifters](https://reader034.vdocument.in/reader034/viewer/2022050715/5d58de7b88c9932c558bc803/html5/thumbnails/20.jpg)
2.1.1 Humidity infuence on Polyamide fabrics
Humidify the mesh by either:
Store the rolls or cut panels in a room or cubboard
with high (95%) humidity
Leave the cut panel in a bucket of cold water
for 1/2 hour
Take it out and leave it hanging for
1/2 - 1 hour

PET-GGGrit Gauze
The rough fabric surface
makes the product remain
longer on the sieve. This
leads to better separation.
• hardly affected by humidity
• resistant to temperature
changes
• keeps constant tension.

Vibro / Turbo sifters
are used to sift the
products from the
filters and bran
finishers
They are highly
efficient, but they need
frequent controls
