当前，我国粮食烘干机（烘干塔）市场处于发育期，由于社会保有量很低，各级政府补贴扶持力度持续加大，因而市场空间巨大，市场发展速度惊人。 目前，烘干机用户多是粮食粗加工企业、种粮大户、农业合作社等农村经济合作组织。购买资金也多来自于各级政府财政补贴和政府项目，用户自筹资金只占一少部分，甚至政府支持力度大的个别地区，用户购机几乎不用出钱。由于这些非市场化因素的存在，加上缺少政府与行业部门的有效监管，目前我国烘干机市场可谓鱼龙混杂、乱象丛生。除进入市场较早的“三久”“一鸣”等民族品牌以及“金子”“山本”等进口品牌一直坚持高端高价，发展相对稳定外，后来蜂拥而入的多数品牌大多选择低端低价战略，使得烘干机市场竞争白热化和复杂化。个别投机型厂商不惜“赔本赚吆喝”，甚至故弄玄虚、炒作概念，误导消费者。笔者结合一些市场乱象谈些个人见解，以期帮助广大用户走出误区。 一、烘干时间过短未必就是高效 水稻等粮食作物干燥是一个非常复杂的量变过程，这是由谷物自身特性所决定的。专业技术人员所绘出的谷物水分蒸发过程所耗费时间的曲线几乎与抛物线吻合。通俗地说，当谷物自身水分高达20%—30%时，平均每小时可下降1—2个百分点甚至更多的水分；当谷物自身水分下降至15%—20%时，平均每小时下降水分可能会在0.3%—1%之间；当谷物自身的水分在15%以下时，每个小时水分的蒸发量可能会更低。 正规的烘干机厂家为保证烘干谷物的质量，通过电子信息技术控制热量来实现烘干机能够按照上述抛物线渐次下降运行。如果一味追求烘干时间（俗称“降水率”），则烘出来的粮食品质势必会大大下降，不仅爆腰率、碎米率高，而且色泽浑浊，品相和营养价值也会受到影响。 二、使用成本未必取决于机器本身 使用成本更多取决于燃料成本，循环式烘干机的工作原理就是将热能转换成热风，然后再通过热风循环达到蒸发谷物水分的目的。 市场上常见的循环式烘干机基本上都可以与燃烧油料、天然气、电、煤炭以及各种生物质的燃烧器相匹配，其使用成本更多地取决于所选择的燃料，而非烘干机本身。即便是不同产品因自身结构设计、精密程度等原因而有所差异的话，其差异也微乎其微。用户在选择购买时，一定要多关注整机产品的设计结构和生产工艺等，切不可被个别无良厂商“忽悠”。 三、国产品牌未必都不如舶来品 由于我国基础工业起步较晚，在机械产品整体性能上与国外品牌还有一定差距，但也并非样样都落后。 在谷物类烘干机行业，“金子”“山本”等日本品牌在水分仪、电控箱等部件上表现的确更加稳定，但“三久”“一鸣”等民族品牌在用料、做工上也毫不逊色，例如“一鸣”系列烘干机产品，一改业界传统的搅龙式送粮方式，全球首创输送带送粮结构，不仅破解了谷物烘干过程中粮食破损率高的难题，而且凭借此项专利技术，给用户带来不小的实惠。按破损率降低两个百分点算，每台10吨烘干机每天烘干一仓粮食，即可减少损耗200公斤（价值大约500元）。 四、一味的低价位不等于高性价比 笔者曾对业内一些企业做过调研：平均每生产销售一台10吨烘干机，材料、设备购置成本4.8万—5.2万元，财务成本2500—3000元，税收2500—3000元，生产制造成本6000元，销售推广费用每台约5000元，售后三包费用约5000元，这些直接费用约6.9万—7.4万元。若再计算厂房、设备的折旧费摊销及合理利润等项目，即使不考虑研发费用，出厂价至少8万—9万元。可是，市场上一些产品的终端售价却远远低于这个价格，令人费解。依笔者分析，不是偷工减料，就是原本就打算放弃对用户的服务承诺。对于厂家来说，这两条道路都是不归之路。

At present, China's grain dryer (drying tower) market is in the development stage, due to the low social holdings, government subsidies at all levels to support efforts to continue to increase, so the market space is huge, the market is developing at an alarming rate. At present, most of the users of the dryer are grain processing enterprises, large grain farmers, agricultural cooperatives and other rural economic cooperation organizations. Since the purchase of funds from governments at all levels of financial subsidies and government projects, self financing only a small part of the user, and even a large number of government support for individual areas, users purchase almost no money. Due to the existence of these non market factors, coupled with the lack of effective supervision of government and industry sectors, the current market can be described as drying machine cohabitation, chaos. In addition to enter the market earlier "three long" "Yiming" and other national brand "gold" and "mountain" and other imported brands always adhere to high-end, development is relatively stable, then most of the brands swarmed into mostly low-end low-cost strategy, the market competition heated dryer and complicated. Individual speculative vendors at the "peibenzhuanyaohe", and even kick up a cloud of dust the concept of speculation, misleading consumers. The author talks about some of the market chaos some personal opinion, in order to help the majority of users out of misunderstanding. First, the drying time is too short may not be efficient rice and other food crops is a very complex process of quantitative change, which is determined by the characteristics of the grain itself. The curve of the time spent by the professional and technical personnel in the evaporation process of grain moisture is almost in agreement with the parabola. Generally speaking, when the grain moisture up to 20% and 30%, the average hourly rate of 1 - 2 percentage points or more water; when the grain moisture decreased to 15% and 20%, the average hourly water drops may be in 0.3% - 1%; when its grain moisture in the below 15%. The evaporation of water per hour may be lower. Normal drying machine manufacturers in order to ensure the quality of dried grain, through the electronic information technology to control the heat to achieve the drying machine can be operated in accordance with the parabola gradually decline. If the blind pursuit of drying time (commonly known as the "precipitation rate"), then bake it will greatly decrease the quality of food, not only crack rate, broken rate is high, and the color turbidity, appearance and nutritional value will be affected. Two, the use of cost may not depend on the machine itself cost depends more on the cost of fuel, the working principle of the circulating drier is converting heat into hot air, and then through the hot air circulation reached the purpose of grain moisture evaporation. The common market circulating drier can basically match the combustion of oil, natural gas, electricity, coal and biomass burner, its cost depends more on the choice of fuel, and non drying machine. Even if the different products due to their structural design, precision and other reasons, but the difference, the difference is minimal. When users choose to buy, we must pay more attention to the design of the whole product structure and production processes, etc., must not be a few unscrupulous vendors flicker". Three, domestic brands are not as exotic as China's basic industry started late, the overall performance of mechanical products and foreign brands have a certain gap, but it is not everything behind. In the grain drying machine industry, "gold" and "Yamamoto" and other Japanese brands in the water meter, electric control box and other components on the performance is more stable, but the "three long" "Yiming" and other national brands in the materials and workmanship favorably, such as "Yiming drying machine" series of products, a change in the traditional industry the auger type food, the world's first grain conveyor belt structure, not only break the grain drying process damaged the difficult problem of the high rate, but also by virtue of the patented technology, bring no small benefit. According to the damage rate reduced by two percentage points, each 10 tons drying machine drying a grain of grain per day, you can reduce the loss of 200 kg (worth about $500). Four, a low price is not equal to the high cost of some industry enterprises the author has done research: the average production of 10 tons of sales of a drying machine, material and equipment purchase cost 48 thousand to 52 thousand yuan, the financial cost of 2500 - 3000 - 2500 yuan, tax 3000 yuan, the production cost of 6000 yuan, sales promotion expenses each about 5000 yuan, three customer service package costs about 5000 yuan, the direct costs of about 69 thousand to 74 thousand yuan. If the plant, equipment depreciation and amortization of reasonable profit and other projects, even without considering the cost of R & D, ex factory price of at least 80 thousand - $90 thousand. However, the terminal price of some products on the market is much lower than the price, puzzling. According to the author, not Jerry, is originally intended to give up on the user's service commitment. For manufacturers, these two roads are not the way back.
