Natural drying is the use of solar radiant heat or blow drying in natural conditions, natural drying is simple, low production costs, and can also promote the maturation of immature raw materials, as long as the method is appropriate, the climate conditions are appropriate, can also be obtained Good dry products. However, natural drying is greatly affected by climate and regional conditions. Drying speed is slow, product quality changes greatly, and products are also easily contaminated. Especially in the dry season, continuous rain is encountered. The dewatering of raw materials is difficult, the process is prolonged, and the quality of the product is reduced, and even mildew corrupt.

Natural drying includes drying and drying. Raw materials that are directly exposed to the sun are called sun-dried or sun-dried; raw materials are blown dry in a well-ventilated room and are called dried or dried.

The main equipment for natural drying is drying field and drying equipment, such as drying plate, seat foil and so on. The drying yard requires sunny air, good ventilation, convenient transportation, convenient work, and as close as possible to the origin of raw materials. It should be kept away from feedlots, apiaries, traffic arteries, garbage dumps, and other sources of pollution to keep the site clean and sanitary. The squeegee is a utensil for loading raw materials on the drying floor. The selection and shape of the drying trays are based on local materials, economical and durable, non-polluting foods, and easy cleaning. Generally use wood or bamboo material for the growth of 90-100 cm, width 60-80 cm, height 3-4 cm flower bottom frame is appropriate.

When dry, a simpler method is to place the raw material directly on the drying floor or on the mat to dry it, or to hang it, or set up a bracket in the drying area, put on the foil or shelving the drying tray, which is helpful for accelerating drying and Improve product quality. Slop the sunroof mat foil southwards to maintain an angle of 15-30 degrees with the ground, or use the terrain to tilt the sunbathing site to a certain southerly angle. You can also move the drying trays and mat foils eastwards in the morning and westwards in the afternoon to 15 floors with the ground. From the left and right angles, in order to increase the irradiation angle and radiation intensity of the sun and the sun's rays on the drying tray and the seat foil, the sun-burning phenomenon caused by strong sunlight at noon can be prevented.

In the process of drying, care should be taken to prevent rain, birds and beasts from harming. When it rains, the raw materials are collected and piled up, and the sun shines after sunrise. And pay attention to constantly turning raw materials to speed up the drying speed, when the bulk of the raw material moisture has been eliminated, should be short-term accumulation, so that it is wet and then drying, is conducive to thorough drying, drying effect is better.
