Procedure for cereal heat treatment entails heating and cracking cereals in opposed heat transfer medium streams with defined heating speed and with through-flow in opposed streams maintained at defined rate

摘要

The procedure for cereal heat treatment entails heating and cracking the cereals in opposed heat transfer medium streams with a heating speed of 5-30 deg C/s, and preferably 12-30 deg C/s. The cereal through-flow in opposed equal flow streams is maintained in a region of Nw=0.5-2.0 kg/kg, and in opposed reverse flow streams a weight loading on the cross sectional face of a mixing pipe is maintained in a region of Gg/FDfm=20-80 kg/m2. An Independent claim is included for a plant to carry out cereal heat treatment consisting of a series of stages (2-4) and pairs of accelerator pipes (5) connected to bypass pipes (6).
