[0027] Example 1
[0028] A production process of black tea powder bread, the process includes the following steps:
[0029] 1) Coarse crushing of black tea leaves
[0030] The black tea leaves are coarsely pulverized with a pulverizer (GPSJ-8 type pulverizer) to obtain coarse black tea powder; the conditions for the coarse pulverization are: a feed amount of 25 kg, a rotation speed of 2500 r / min, and a time of 1 min.
[0031] 2) Extrusion of black tea leaves
[0032] Put the black tea coarse powder into the feeding trough of the twin-screw extruder (SHJ-30 type) at a feeding speed of 25kg / h, and spray water on the black tea coarse powder at the entrance of the auxiliary material of the extruder. Humidification; the rotation speed of the twin-screw extrusion set is 100r / min, the temperature is 130°C, and the humidification amount is 2kg / h.
[0033] 3) Superfine crushing of black tea powder
[0034] The tea powder obtained in step 2) is superfinely pulverized by a pulverizer (CWJ-30 type ...
