Horizontal-type solid fermentation tank and fermentation method for Pu-erh tea

Abstract

The invention discloses a horizontal-type solid fermentation tank and fermentation method for Pu-erh tea. The fermentation tank comprises a tank body supported by a tank body support, and a clamp jacket is installed outside the tank body; the top of the tank body is provided with feed inlets, exhaust ports, diversion plates connected with heating wires, a water inlet and a water replenishing and inoculation opening; the bottom of the tank body is provided with a discharge outlet, a water vapor inlet, a sterile air inlet, a carbon dioxide inlet, a drying ventilation opening and a water outlet, and a stirring system is further arranged in the tank body. According to the fermentation method, a traditional Pu-erh tea pile-fermentation technology is changed, production standardization and specification rationalization of the Pu-erh tea are achieved on the condition that fermentation conditions such as microorganism species, tidal prism, temperature, fermentation time, inoculated-pathogen quantities and oxygen and carbon dioxide content of the Pu-erh tea are comprehensively considered, the fermentation process of the Pu-erh tea is artificially controllable, and the quality of the Pu-erh tea is more stable, safer and more controllable.

Description

technical field [0001] The invention relates to the technical field of Pu'er tea processing, in particular to a Pu'er tea horizontal solid fermentation tank and a fermentation method. Background technique [0002] Pu'er tea is a special kind of tea with mellow taste, reddish-brown soup color, outstanding aging aroma, and reddish-brown leaf bottom, which is made of Yunnan big-leaf sun-dried green tea as raw material through a specific post-fermentation process. The fermented tea is called Pu’er raw tea), which has various health effects such as eliminating food and greasy, promoting body fluids and quenching thirst, relieving fatigue and eliminating troubles, reducing fat and blood pressure, anti-aging, and anti-cancer. The earliest Pu-erh ripe tea is naturally stored and fermented slowly for a long time. Whether it is the early natural fermentation or the traditional fermentation method currently used, there are certain defects, such as long fermentation cycle, unstable pro...

Problems solved by technology

For example, the "Double-layer Moisturizing and Rotating Pu'er Tea Fermentation Tank" developed by Zhou Hongjie of Yunnan Agricultural University (application number 200920111698.9) adopts a horizontal stainless steel structure, and only has a bracket, a tank body, and a drum stirring device. The tank body is equipped with a feeding port and a drain port. And other devices, which can control fewer parameters, the fermentation quality is still difficult to guarantee
