The invention provides a purple sand sintered body for coffee
aroma enhancement and a preparation method and application thereof, and belongs to the technical field of purple sand materials.The purple sand sintered body for coffee
aroma enhancement is prepared by mixing and firing small
coal kiln cinnabar clay purple sand pug and Benshan
cinnabar clay purple sand pug according to the
mass ratio of (80-50): (20-50), the content of Fe2O3 in the Benshan
cinnabar clay purple sand mud is not less than 9.0 wt.%, the content of
trace element Cu in the small
coal kiln cinnabar clay purple sand mud is not less than 40 mg / kg, and the content of K2O is not less than 2.5 wt.%. According to the purple sand sintered body for coffee
aroma enhancement, other preparations do not need to be additionally added, only a small
coal kiln cinnabar clay purple sand pug rich in
copper and
potassium and a Benshan cinnabar clay purple sand pug rich in iron are mixed, and an iron-based multi-element catalytic
system is constructed by adjusting the
mass ratio of the two pugs. Furthermore, a
sintering process is optimized, a confinement space is created, and the synergistic effect of the multi-element
metal catalyst is enhanced, so that the generation efficiency of the
coffee flavor substance is remarkably improved.
