Description
Technical field
The present invention relates to corn processing technical field, and in particular to a kind of tower-type maize dryer and its furnace drying method.
Background technology
With the continuous propulsion of mechanization of agriculture, the plantation of corn and harvest process constantly develop to modern mechanicalization,
Much regional in China, the harvest season of corn is mostly rainy season, and corn is tedded by the way of traditional, weather can be limited by, because
This, can be prevented effectively from these problems using corn drying machinery drying corn and save drying cost.Relevant information shows：One labor
Power Exposure to Sunlight corn 400kg needs 35 yuan of wage, and mechanical drying 400kg corns need 32 yuan, 3 yuan of contrast reduction.And machinery dries
It is dry better than the corn quality manually dried, in good taste.After corn is dried by low-temperature circulating, quality can improve a grade, sell
Valency also accordingly increases.In addition, purchase dryer is more profitable than laying threshing ground.1 medium-sized corn picker day harvesting corn
13.5~22.5 tons, such as shine 2 days, need 3000 square metres of cement threshing ground, 300,000 yuan or so of investment gold, and ted inequality naturally
Even, loss late is up to 3%, and loss is high, especially has considerable influence to the bud ratio of seed, runs into the cloudy day and rains, threshing ground can not be used.
Therefore, drying processing is carried out to corn relative to manually tedding with a variety of absolute predominances using corn drying machinery.
Corn drying process is a complicated heat transfer, passes wet process, the biochemistry of simultaneous cereal in itself
Quality comparison.In the drying process, moisture unnecessary in corn is not only reduced, the standard of safe storage, Er Qieyao is reached
Ensureing the quality of corn does not reduce and is improved as far as possible.On the one hand, dryer of the prior art be concentrated mainly on paddy, it is small
On the crops such as wheat, on the other hand, because drying is too fast, temperature is too high, the quick-fried waist of grain easily occurs, and the phenomenon such as cracking is dried
Journey greatly reduces the quality of corn, in addition, the waste gas produced during corn-drying carries a large amount of dust, is exhausted directly to air
In can cause environmental pollution.
The content of the invention
The present invention overcomes the shortcomings of that prior art is present, and technical problem to be solved is：A kind of drying dewatering mistake is provided
