specific Embodiment 2
[0033] A processing technology for combined drying of ginseng, comprising the following method steps:
[0034] 1. First, wash the ginseng, remove the reed head and fibrous roots, select the ginseng with an initial moisture content of 73.5%, cut it into slices with a thickness of 3.5mm according to the specifications, and send it to a low-temperature refrigerator. The temperature of the refrigerator is set at 2.5 ºC. Until the temperature of the ginseng slices is the same as the room temperature in the refrigerator, remove the ginseng slices and place them at room temperature for 5 hours before preparing for microwave drying;
[0035] 2. Put the ginseng slices into the microwave drying device, fix the heating mode, perform the first step of drying, and dry in the microwave device for 133s;
[0036] 3. After the first stage of microwave drying, the ginseng slices enter the second stage of tempering drying. Put the ginseng slices into a closed far-infrared drying oven. The temper...

Abstract
The invention discloses a processing technology for combined drying of ginseng slices. The processing technology includes the steps that firstly, ginseng is pretreated; secondly, the ginseng slices are dried for 133 s with microwaves; thirdly, tempering drying is conducted, and then far infrared high-temperature drying is conducted; fourthly, natural cooling is conducted, and dried ginseng is obtained. An improvement is conducted based on a traditional drying technology, the drying mode of combining microwave drying and far infrared drying in series is conducted so that the loss of the quality of the prepared ginseng and internal nutrient ingredients can be lowered, the drying time is shortened, meanwhile, the drying mode is environmentally friendly, and energy consumption is low.
Description
technical field [0001] The invention relates to the technical field of food processing, in particular to a processing technology for combining and drying ginseng slices. Background technique [0002] There are many kinds of ginseng, such as ginseng, American ginseng, dangshen, heterophylla, northern ginseng, and southern ginseng. According to its quality and place of origin, it can be divided into wild ginseng, garden ginseng, and Korean ginseng. As long as wild ginseng grows in my country's northeast regions such as Jilin and Heilongjiang, the output is very small. At present, garden ginseng is more common in the market, which is artificially planted and cultivated in gardens. According to different processing methods, garden ginseng is divided into several types such as raw sun-dried ginseng, red ginseng, and sugar ginseng. Korean ginseng refers to ginseng produced in South Korea or North Korea. In China, most of the common Korean ginseng on the market is Korean ginsen...
