The invention relates to a flour heat treatment
processing process. Traditional wheat-processed flour is conveyed into a heat
treatment unit by a pre-set flow; the heat
treatment unit comprises at least one grade of a spiral conveyor with a jacket layer, which is sequentially connected in series; the flour enters from a feeding hole of the first-grade spiral conveyor and is output from a discharging hole of the last-grade spiral conveyor; in a flour conveying process, steam is introduced into the jacket layer of each grade of the spiral conveyor, and food-grade steam is introduced into a conveying chamber of the first-grade spiral conveyor at least to be mixed with the steam, and a
spiral blade propels and stirs; the flour subjected to the heat treatment is output through a conveying pipeline; in the flour conveying process, the flour is sufficiently scattered through a high-speed online
crusher; the scattered flour is rapidly cooled and the
moisture content is rapidly reduced in
drying equipment; and finally, the flour is unloaded and stored. According to the flour heat treatment
processing process, modification and gelatinization of
starch and proteins in the flour are realized through steps of online continuous steam humidification and heating and the like, so that the performance of the flour is greatly improved.
