After harvesting fresh ginger, rinse it clean with water, peel it by hand or with a peeling machine, and cut it with a knife or slicing machine into evenly sized slices about 1 cm thick. Set up bamboo racks in a sealed room, place the ginger slices on the bamboo racks, and dry the ginger slices directly in the sun to obtain dried ginger slices. Where conditions permit, baking can be carried out: put the sliced ginger into a drying room, and strictly control the temperature in sequence with high, medium, and low heat. Start with high heat to gradually evaporate the moisture on the surface of the ginger slices, then lower it to medium heat and low heat, so that the ginger slices shrink and cool, becoming hard and crisp, with a moisture content of 12%

Three practical methods for storing wheat, simple and easy to carry out
Heat-sealed method: Choose a clear, hot day, and around 9 a.m. after the drying yard has been heated by the sun, first move out the tools and materials (cotton quilts, burlap pieces, etc. all work) to air and dry in the sun. The wheat must be turned frequently so that the wheat temperature rises to 48-52°C in the sun and the moisture drops below 12.5%. Around 3 p.m., pile it up, let it sweat hot for half an hour, and while still hot put it into the jar. Use materials that have been disinfected and dried in the sun to press down and cover it, then seal it with plastic film so that no air leaks, keeping the grain temperature above 40°C for 8-10 days to kill eggs, pupae, larvae and adults, achieving the effect of accumulating heat to kill insects.
