摘要： The invention relates to a method for drying pasta products in which during the drying process the pasta products, which are present as raw pasta shapes, pass through surface states that exhibit differing value pairs of surface temperature (T) and surface moisture (U), and wherein during the drying process the surface of the raw pasta shapes remains in a viscoelastic state in which in a diagram of surface temperature (T) of the raw pasta shapes and surface moisture (U) of the raw pasta shapes (a.) the surface temperature (T
v ) of the raw pasta shapes is not greater than 4O°C more than the temperature (T
g ) on the glass transition curve of the raw pasta at the point of equal moisture of the surface, and/or (b.) the moisture (U
v ) of the surface of the raw pasta shapes is not more than 20% greater than the moisture on the glass transition curve of the raw pasta at the point of equal temperature of the surface. This facilitates an especially rapid drying of the pasta products without any detriment to quality.-

摘要： The invention relates to a method and device for separating a mixture (1), made of particles of a first particle type (2) and a second particle type (3), especially aleurone particles and shell particles made of comminuted bran, said particles being scarcely distinguishable in terms of size and density, into various types of particles (2, 3). Separation occurs according to particle-type specific tribo-electric charging of said particles in a first active area (13, 14; 27, 28) and subsequent separation of the differently charged moving particles in an electric field.
