Nowadays, grain drying has become a hot topic. The majority of farmers urgently need to be freed from the large amount of physical labor brought about by the drying operation of the grain, and use limited investments, including equipment investment and fuel consumption investment in exchange for production protection, for at least ten years. China's grain machinery drying and precipitation has a history of nearly 50 years. It can be said that China has basically grasped the grain drying equipment. Small grain dryers have a great market.
The development of foodstuffs and equipment is a requirement for adapting to the changing climate conditions in China. The precipitation of rural food in China is mainly based on natural drying. This operation method is largely constrained by weather conditions. According to the analysis provided by the meteorological department, China The main food producing areas are in the prone period of rainy weather in the harvest season. According to statistics from authoritative departments, the amount of loss of timely drying of food in rural China is quite alarming. The total annual production volume is 10, and the serious year is 15. In recent years, due to the global El Niño phenomenon, local or regional The phenomenon of abnormal climate in large areas has occurred from time to time, with frequent floods and floods. This phenomenon of natural disasters occurred during the harvest season, it may cause a large area of ​​grain production, some areas even missing.
Our province is located in the transitional zone between North and South, with a humid and rainy climate, ripe grains, a small harvest for development and a food factory, and a high-quality measure of grain quality and poor value of grain production. Mechanical Drying Compared with natural drying, the former It is more conducive to maintaining food quality. The practice of large-scale grain storage has proved that the speed of food grain aging mainly depends on the grain moisture content and grain temperature during the storage period.
On the one hand, the higher the moisture content, the higher the grain temperature, and the shorter the food can be safely stored. On the other hand, if the grain moisture content is too low, it will also affect certain qualities of grain. Take rice as an example. When the moisture content is too low, the waist burst rate increases significantly, broken rice is more, and the taste is poor. The drying and drying of grain is affected by various factors such as the initial moisture content of the grain, the operating conditions of the site conditions, etc., and it is difficult to obtain a more accurate moisture value, which makes it vulnerable to stealing and eating. Impurities, dust, and other environmental pollution also require more space. Mechanical drying can better control the moisture of the grain, and can also avoid the above-mentioned defects.
