Abstract

The invention provides a preparation method of dried zanthoxylum bungeanum maxim. The preparation method of the dried zanthoxylum bungeanum maxim comprises the following steps of naturally air-dryingpicked fresh zanthoxylum bungeanum maxim; dehumidifying with hot air: sequentially drying the naturally air-dried zanthoxylum bungeanum maxim in a drying chamber at 32 + / -0.5 DEG C for 2 + / -1 hours, in a drying chamber at 35 + / -0.5 DEG C for 3 + / -1 hours, and in a drying chamber at 37 + / -0.5 DEG C for 3 + / -1 hours; drying in a drying chamber at 39 + / -0.5 DEG C for 8 + / -1 hours to enable zanthoxylum oil to overflow out of the surface; drying in a drying chamber at 41 + / -0.5 DEG C for 9 + / -1 hours; drying the zanthoxylum bungeanum maxim subjected to the previous step in a drying chamber at 43 + / -0.5 DEG C for 5 + / -1 hours, and then drying the zanthoxylum bungeanum maxim in a drying chamber at 45 + / -0.5 DEG C for 3 + / -1 hours; and in the drying process, heating cold air by a heater and introducing into the drying chamber, and introducing generated damp-hot air into a heat exchanger as a heat source for preheating cold air. According to the preparation method of the dried zanthoxylum bungeanum maxim provided by the invention, waste heat recovery is achieved, power consumption is greatly reduced, emission of air containing pollutants is fundamentally eradicated, and energy conservationand emission reduction of pepper drying are achieved.

Description

Technical field[0001]The invention relates to the processing of Zanthoxylum bungeanum, in particular to a method for preparing dried Zanthoxylum bungeanum.Background technique[0002]There are two main methods for preparing dried prickly ash. One is to use electric heating with air heat source pump as heat source to dry prickly ash, and the other is to use combustion heat (such as the heat source generated by burning coal, natural gas, gas, etc.) The disadvantages of using the heat source to dry the prickly ash on the kang and drying the prickly ash include high fuel consumption and serious environmental pollution. As the country has stricter environmental protection requirements, most areas have strictly restricted the use of coal. Therefore, the use of electric heating to dry pepper is one of the mainstream trends in the future.[0003]The document CN206709559U discloses a pepper drying device, which includes a drying chamber, a hot blast stove, a flue gas heat exchanger and a blower....
