Description
Technical field
The present invention relates to Tea Processing technical field, especially a kind of LIUPUCHA fermentation process.
Background technology
LIUPUCHA belongs to one of postfermented tea, and the main place of production is area, Wuzhou, Guangxi, and its traditional tea-manufacturing technology is with LIUPUCHA raw tea as raw material, then through screening, assorted, pile-fermentation, decatize curium pressure, ageing, finally obtains LIUPUCHA finished product；Above-mentioned LIUPUCHA traditional manufacturing technique, pile-fermentation is one of requisite operation, traditional fermentation Wo Dui factory way: carry out on special hardened floor, high general about one meter of tea heap, depending on length and width are when Folium Camelliae sinensis, the pile-fermentation time is about 1 ~ 2 month, if it find that tea stack temperature is too high, being also performed to manual stirring, this tradition pile-fermentation technique has following defects that 1) it is easily formed the globule bottom tea heap；Owing to pile-fermentation is to carry out on the dedicated site of hardening, spray water on tea heap, often at tea heap congregate, even occurs time serious that Folium Camelliae sinensis hardens phenomenon, causes fermenting uneven, and defective products rate is higher；2) tea stack temperature is difficult to control；Owing to pile-fermentation uses heap formula, tea heap is tall and big, and under the damp and hot effect with microorganism, tea stack temperature raises, and bottom tea heap, heartburn phenomenon easily occurs in centre position, affects tea heap pile-fermentation quality；3) tea heap turning intensity is big；LIUPUCHA pile-fermentation temperature should control to be preferred at 40 ~ 60 DEG C, and the too high meeting of temperature causes Folium Camelliae sinensis heartburn, and temperature is too low can cause again fermentation uneven, extends fermentation time；Most manufacturing enterprises use artificial turning to control tea stack temperature, and artificial turning not only labor strength is big, and pile-fermentation quality is not easy to control；4) it is easily generated antihygienic sensation；Carry out on the floor in workshop owing to LIUPUCHA pile-fermentation is typically all, although manufacturing enterprise is desirable that workman enters pile-fermentation workshop working clothing to be dressed and shoes and hats, and passage to be carried out disinfection could enter workshop, operating personnel is also wanted to put on the canvas boot of patent during turning, but overall to a kind of antihygienic sensation of people.
