Abstract

The invention relates to the technical field of agricultural product processing, and in particular relates to a two-stage type hot pepper drying method. The two-stage type hot pepper drying method comprises the following steps of (1) preparing hot peppers; (2) performing first-stage drying; (3) evaporating water in the hot peppers; (4) performing second-stage drying; (5) softening and packaging the hot peppers. According to the method for drying the hot peppers, the appearance commodity and the internal quality of dried hot peppers can be obviously improved, the broken shell rate and the white shell rate of the dried hot peppers can be obviously reduced, and the commodity rate, the appearance commodity and the internal quality of the dried hot peppers can be better improved at the same time; the transportation time and the storage time of the dried hot peppers can be prolonged, so that the commodity rate and the economical benefit of the dried peppers are improved. The dried hot peppers treated by the method disclosed by the invention is higher in fruit rate and higher in thickness as compared with the dried hot peppers treated by a conventional method and cannot get damp and mildewed as dried hot peppers which are obtained through drying in shade and drying in the sun; the phenomenon of piebaldness caused by a reason that the dried hot peppers are polluted by mould after being transported or stored for a long time.

Description

technical field [0001] The invention relates to the technical field of agricultural product processing, in particular to a two-stage chili drying method. Background technique [0002] Capsicum is one of the main crop varieties in Guizhou, and it is also the local characteristic economic crop with the most significant increase in farmers' efficiency in Guizhou. [0003] During the harvest season of chili peppers in Guizhou, it is the rainy season all the year round, and the air humidity is high.
