Embodiment 1
[0036] refer to Figure 1-6 , a method for preparing a mulberry leaf black tea liquid beverage and processing equipment, mainly comprising the following processing steps:
[0037] a. First, an appropriate amount of mulberry leaf black tea is placed in a vacuum freeze dryer, and dried for 24 hours at a drying temperature of -20° C. and a vacuum of 0.1 MPa to obtain a freeze-dried mulberry leaf black tea;
[0038] b. The freeze-dried mulberry leaf black tea described in step a is mechanically crushed through a multifunctional pulverizer, and passed through a 100-mesh sieve to obtain mulberry leaf black tea powder;
[0039] c. The mulberry leaf black tea powder described in step b is subjected to constant temperature extraction, the water consumption is twice the mass ratio of mulberry leaf black tea, the extraction temperature is 50°C, the extraction time is 8h, and the supernatant liquid is collected by centrifugation; then the filter residue is repeatedly extracted 1 time, th...
