Low-temperature and low-speed dryers have low manufacturing costs, and farmers in general have the ability to purchase them. Although high-temperature and rapid-drying machines cost slightly, it is economically viable to collectively purchase large-scale or large-scale farmers. Judging from the current data, if Taiwan dryers are used rationally and in Weimai, rice will be harvested in July and October. Since most of the food in the rural areas of our province depends on natural drying and drying, the amount of food produced by mildew and sprouting each year is also quite alarming.
Obviously, if we want to fundamentally change the situation in which food is dependent on weather conditions to create dry conditions, and truly produce bumper crops, we must vigorously develop mechanized dry precipitation.
The high-moisture foods that China needs to handle each year are as high as 100 million tons, which accounts for the total output.
For a long time, the state has to use a lot of financial resources to dry high-moisture food. Grain drying has become a bottleneck that restricts post-production processing and value-added in China. The development and promotion of grain drying equipment is a general trend, and it will surely have much promise and broad prospects.
The development of grain drying equipment is sufficient to meet the needs of rural system reforms in China and the need for rural economic development. Today, the majority of farmers in our country are no longer simply relying on farming. A considerable number of rural laborers have completely left the countryside to engage in various types of non-agricultural work. . Agricultural laborers who are farming at home, or large farming families, urgently need to reduce the labor intensity by using a large number of various agricultural machinery. The dry food is completely similar to the post-harvest operation of grain. The peasants urgently need to be freed from the large amount of manual labor brought about by the drying operation of the grain, and use limited investment including equipment investment and fuel consumption investment in exchange for production and maintenance. 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 output 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 in 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 inferior food production value. Mechanical drying compared with natural drying. 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 other hand, the higher the moisture content, the higher the grain temperature, and the shorter the food can be safely stored. On the other hand, too low a grain moisture content will also affect certain food quality. 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, and the difficulty in obtaining a more accurate moisture value. 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.
