I. Advantages of Ginger Dehydration
1. Enhance ginger’s value
Fresh or raw ginger promotes sweating and dispersing exterior cold. While dried ginger is more effective in warming spleen and stomach and expelling interior cold. Therefore, dried ginger can help relieve indigestion, gas pains, reduce nausea and stomach cramping.
2. More cost-effective
Dried ginger is more concentrated in its chemical composition than fresh ginger. Dried ginger can be stored easily for a long time, the process is, therefore, effective because it lowers the cost of packaging, storing and transportation by reducing both weight and volume of the final product.
3. Wide application
Dried gingers can be processed into different forms like piece, powder, starch, and all of these forms can be applied in many industries.
♦Dried ginger pieces not only have the function of expelling interior cold and dampness but also reduces the bitter feeling when your mouth becomes dried. So it is a common ingredient of cold pills.
♦Ginger powder is normally used in seasoning and pickling vegetables, baking food, flavoring candies, or a beverage such as ginger tea.
♦Dried ginger powder can be further processed into starch, which is isolated from ginger rhizomes. The increased requirements for starches in different applications, such as functional and healthier food, or applications in pharmaceuticals have thus forced a steady development of new starch types.
♦Dried ginger slice can also be steam distilled as ginger oil or eleoresin, which have the function of anti-oxidation and anti-bacterial. The yield of oil from dried ginger rhizomes is between 1.5% to 3.0%. The remaining rhizome powder contains about 50% starch and can be used for animal feed.
II. Hot-Air Circulation Drying Technology
The hot air circulation drying technology used in ginger drying processing is able to ensure a homogeneous temperature, making ginger heated evenly to get a uniform color. This drying oven with automatic temperature control function works smoothly to ensure the end product’s quality.
During drying processing, the fresh gingers are normally processed using Hot-Air Circulation Dryer, which is a tray dryer whose heating source can be supplied by electricity, steam, hot water or far infrared ray, the hot air is blown into the drying oven by the fan and most of the hot air circulate continuously in the drying oven, drying gingers with this system is a cost-effective long-term food storage solution. After drying for several hours, store it in plastic zip lock bags or airtight containers. This dry fresh ginger will store in a moisture free environment for more than a year.
Besides hot air drying, another drying technology-microwave drying is usually applied in drying processing. Microwaves are a form of electromagnetic energy with frequencies between 300MHz and 300GHz, generated by magnetrons under the combined force of an electric and a magnetic field perpendicular to each other.

III. Ginger Drying Processing and Equipment
●Firstly, pick out the broken parts of gingers, then put the fresh ginger on the conveying device, and it is automatically sent into washing tank of Root Vegetable Washing Peeler Machine, which is equipped with automatic spray device to help final washing and peeling.
●Next, peeled ginger is sliced into thin pieces by Ginger Slicing Machine. Before drying, in order to get a brighter colored product, the ginger slices can be blanched by Cooking Blanching Machine, what’s more, blanching can facilitate peeling or kill microbes.
●Then the slices are put on trays of Hot Air Drying Oven for an evenly drying when the slices are spread evenly on the trays, please remember to leave space between the gingers so they’re not touching each other, to allow the hot air to do its job.
●Finally, if you want to further process ginger powder or ginger oil, electric grinder and Oil Extraction Machine can help you achieve these aims.
PS: The ginger powder making process is not difficult to operate, and you can get it even at home. Usually, before grinding into the delicate powder, gingers are dried, cleaned and sorted. Then, the grinding machine can be used to grind ginger paste, through further filtered you can get the pure ginger juice. High efficiency and small size make our mini electric grinder extremely popular for home use.
IV. Ginger Drying Market in the World
