Embodiment 1
[0022] Embodiment 1: Prepare the tea residue solid-state fermentation feed material of this embodiment according to the following method:
[0023] (1) Tea dregs steam explosion sterilization treatment: put the tea dregs into the steam explosion tank, feed 2.2Mpa steam into the steam explosion tank, keep for 3min, open the steam explosion valve, and obtain the tea dregs after steam explosion;
[0024] (2) Dehydration: the tea leaves after steam explosion are extruded or dried by equipment, so that the moisture content is controlled at 50% by mass fraction;
[0025] (3) Fermentation substrate preparation: fully mix 89.98 parts by weight of dehydrated tea leaves, 5 parts by weight of bran, 3 parts by weight of soybean meal, 2 parts by weight of molasses, and 0.02 parts by weight of composite trace elements to make a fermentation substrate; Trace elements consist of 2 parts by weight FeS0 4 ·7H 2 0,0.8 parts by weight MnS0 4 , 0.7 parts by weight ZnS0 4 , 0.8 parts by weight K...
