With the rapid rise of grain dryers, the dryer industry has also followed the trend of rising, indicating that the machinery industry has gradually warmed up. This year is an era of “energy saving and emission reductionâ€. The machinery industry needs to develop new technologies and move toward energy conservation. Let Xiao Bian take everyone with you to understand the drying machine 1, too short drying time is not necessarily efficient The drying process of rice and other food crops is a very complicated process of quantitative change, which is determined by the physical and physiological characteristics of the grain itself. The curve drawn by the professional technicians for the evaporation time of the grain moisture is almost in line with the parabola. In general, when the grain's own moisture is as high as 20% to 30%, it can decrease by an average of 1 to 2% or more per hour; when the grain's own moisture drops to 15% to 20%, the average Drops of moisture per hour may be between 0.3 and 1 percentage point; when the grain's own moisture is below 15%, the evaporation of moisture per hour may be lower. In order to ensure the quality of dried cereals, regular dryer manufacturers use electronic information technology to control the heat to achieve a gradual descending operation of the dryer according to the aforementioned parabola. If users are misled and tempted by individual unscrupulous manufacturers, blindly pursuing drying time, the quality of dried food will inevitably be greatly reduced, not only with a high waist rate, a high rate of broken rice, but also with a turbid color, product phase and nutritional value. affected. 2, the use of more cost is dependent on fuel costs The working principle of the circulating dryer is to convert heat energy into hot air, and then use the hot air circulation to achieve the purpose of evaporating the grain moisture. The common circulation dryers on the market can basically match the burners of burning oil, natural gas, electricity, coal and various vegetable substances. The cost of use depends more on the fuel selected than the drying. Machine itself. Even if different products are different due to their own structural design, precision, etc., the difference is minimal. When the user chooses to purchase, he must pay more attention to the design structure and production process of the entire product, and must not be “fudged†by individual unscrupulous manufacturers. 3, domestic brands may not be as good as imported products Due to the late start of China's basic industries, there is still a certain gap between the overall performance of mechanical products and foreign brands, but not all of them are lagging behind the “East Asiaâ€. Such as cereal dryer industry, gold, Yamamoto and other Japanese brands in the moisture meter, electronic control box and other parts of the performance is indeed relatively stable, but Yiming and other domestic brands in the use of materials, work is not inferior, especially in Taizhou The Mingming series of dryers produced by Mingming Machinery Equipment Co., Ltd. have changed the industry's traditional auger-type food delivery method, and the world’s first conveyor belt to send grain structure has not only effectively cracked the high rate of grain breakage during grain drying. The problem, and this patented technology brings a lot of benefits to the user. According to the reduction of breakage rate by two percentage points, each 10-ton dryer will dry one grain of food per day, which will reduce the loss of 200kg. The value is about 500 yuan. 4, blindly low price does not mean that cost-effective According to a survey, the average cost for producing and selling a 10-ton dryer is: the cost of materials and equipment is between 48,000 and 52,000 yuan, the financial cost is between 2500 and 3,000 yuan, and the tax is between 2500 and 3,000 yuan. , together with the manufacturing cost of 6,000 yuan, the sales promotion cost of about 5,000 yuan each, and the after-sales three-pack cost of about 5,000 yuan, these direct costs will be between 69,000 and 74,000 yuan; if the depreciation cost of plant and equipment is recalculated For projects with reasonable profit and other cost, even if R&D expenses are not considered, the ex-factory price is at least between 80,000 and 90,000 yuan. In addition, various equipment companies must also pay attention to energy saving and comprehensive energy utilization in the development process, such as adopting various joint heating methods, transplanting heat pump and heat pipe technology, developing solar dryers, etc., and developing drum dryers. The automatic control technology to ensure the realization of optimal operating conditions; In addition, with the human attention to environmental protection, improve the drum dryer environmental protection measures to reduce the leakage of dust and exhaust gas, etc., will also require in-depth study The direction.
