Ginger rapid drying device

Abstract

The invention discloses a ginger rapid drying device, which comprises a machine body, a fluidized bed and a ginger conveying wire belt penetrating the machine body, wherein the machine body is sequentially divided into a shortwave infrared heating area, a medium-wave infrared heating area and a far-infrared heating area, a shortwave infrared heating pipe nest is arranged on the inner upper part of the shortwave infrared heating area, a medium-wave infrared heating pipe nest is arranged on the inner upper part of the medium-wave infrared heating area, a far-infrared heating pipe nest is arranged on the inner upper part of the far-infrared heating area, the top of the far-infrared heating area is provided with an air inlet, and the top of the shortwave infrared heating area and the top of the medium-wave infrared heating area are respectively provided with an air outlet; and the fluidized bed comprises a bed body and a blower, wherein the blower is communicated with the bed body, the bed body is provided with an air blowing hole, and the bed body of the fluidized bed is arranged inside the shortwave infrared heating area and the medium-wave infrared heating area and is closely abutted against the lower side of the ginger conveying wire belt. By adopting a way combining the infrared heating and the fluidized bed as well as the hot air circulation, a purpose for rapidly drying ginger is realized, and simultaneously the ginger can be prevented from being discolored.

Description

technical field

[0001] The invention relates to a drying device, in particular to a ginger quick drying device. Background technique

[0002] China is one of the countries with the largest ginger production in the world, but fresh ginger is prone to mildew, wrinkled skin, shriveled and deteriorated in storage, and it is not easy to store for a long time. Ginger is processed into ginger slices or ginger grains, and then dried and stored, which not only solves the storage and transportation problems of ginger, but also enriches the market for ginger products and is more convenient to eat.

[0003] The traditional ginger drying method is hot air convection heating and drying, but this method is very inappropriate for ginger drying. On the one hand, the drying speed is slow and the drying time is long. On the other hand, the ginger is easy to dry during the drying process. For discoloration, a special color protection process needs to be added, otherwise the excellent dried gi...
