4.2 Sieving. Sieving is a common method to separate particles and is primarily based on particle size difference, where this can use as an alternative technique for air classification. A stack of sieves with decreasing mesh sizes or single sieving steps with increasing mesh sizes can be used. Sieving has been investigated for the protein enrichment of pea flour.
