Problems solved by technology

For example, Chinese patent CN201110273316.4 discloses a dark tea production process, including finishing, rolling, stacking, drying 1, steaming, pressing, fermenting, and drying. Heaping is all done manually and by experience. The heaping time is long, the middle of the heap is often over-fermented, and the edge of the heap is often under-fermented. The quality is difficult to control, resulting in the color, aroma, taste, shape and quality of the bottom of the finished black tea. , the quality of each batch of tea is different, especially when the output of fresh tea leaves is large, the processing is not timely, resulting in damage to the fresh tea leaves, and no high-quality dark tea can be produced.
Most of the traditional dark teas are loose in shape, low in aroma and flat in taste, and even over-mugged, sour and sour, and lacking in quality, which poses a great food safety hazard

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a processing method of dark tea. Background technique [0002] There are hundreds of chemical substances in black tea, such as proteins, amino acids, vitamins and other substances that can increase human nutrition, as well as substances that can prevent diseases such as tea polyphenols, caffeine, lipopolysaccharides, etc. With the effect of reducing fat and losing weight, dark tea has become the development direction of the tea industry. [0003] At present, the basic technological process of most black tea production is greening, initial kneading, fermenting, re-kneading, and baking. For example, Chinese patent CN201110273316.4 discloses a dark tea production process, including finishing, rolling, stacking, drying 1, steaming, pressing, fermenting, and drying. Heaping is all done manually and by experience. The heaping time is long, the middle of the heap is often over-...
