Abstract
The invention discloses a continuous vacuum far-infrared low-temperature grain drying machine. According to the continuous vacuum far-infrared low-temperature grain drying machine, the grains pass a feeding hopper, a vacuum rotary feeding valve, a discharge port of the vacuum rotary feeding valve and multiple vacuum drying discs, wherein an interval is arranged between the discharge port of the vacuum rotary feeding valve and each vacuum drying disc, so that the grains are evenly spread on the vacuum drying disc along rotation of the vacuum drying disc; material arranging scrapers are arranged in passageways of the vacuum drying discs, so that the grains reach the material arranging scraper of one vacuum drying disc along rotation of the vacuum drying disc are arranged for the vacuum drying disc of the next level; a far-infrared heating device is arranged above the vacuum drying disc, the grain-drying material layer is thin and the far-infrared thermal radiation is sufficient, so that slow and uniform heating of the grains are ensured; moreover, continuous grain-drying is assured; and vacuum pipes are arranged between the vacuum drying discs, so that hot air and wet steam can be later sucked away through the vacuum pipes. The grains are cooled by a cooling section, then discharged through a vacuum rotary discharging valve into a lifting machine.
Description
Technical field
The present invention relates to technical field of electric automation, especially a kind of continous vacuum far infrared low temperature crop dryer.
Background technology
Vacuum drying has many advantages: time under low pressure dry, oxygen content is low, can prevent dried material oxidation deterioration, can dry inflammable and explosive dangerous material; The moisture in material can be made at low temperatures to vaporize, be easy to dry heat sensitive material; Valuable and the useful composition in dried material can be reclaimed; The discharge of poisonous and harmful substance in dried material can be prevented, the green drying of environmental protection type can be become.Far infrared has stronger penetration capacity, and is easy to absorbed by material and be converted into heat energy therein, moisture can be made to vaporize, reach the object of dried grain.Far infrared grain dry speed is fast, and quality is good, and dehydration is evenly, pollution-free to cereal, is conducive to long storage periods, consumes energy low in dry run.The now widely used Series-airflow dryer of China's grain drying, the subject matter existed is: the temperature of hot blast is generally at 120 ~ 160 DEG C, in the process of drying, high-temperature hot-air is to grain dry, if drying process control is improper, and the cracking breakout of corn, percentage of damage, Cracked Rice rate, the acute height of the rate of going rancid of oil plant not under, cause quality to decline, had a strong impact on domestic and international trade.Simultaneously drying capacity is not enough, and it is numerous and jumbled to dry type, and stoving process falls behind, and civilwork engineering quantity is large, and generalization, standardization, seriation degree are extremely low, and the thermal efficiency is low, and specific energy consumption is high ...And China's grain dry mainly uses coal and oil as fuel, be difficult to meet environmental protection and dry the not contaminated requirement of grain, when adopting oil oven; because quality nozzle does not pass a test, cause fuel atomization effect poor, burn insufficient; both cause the waste of fuel oil, cause environmental pollution again.Meanwhile, compare maximization, mobile difficulty, cannot a tractor serves several purposes.
Summary of the invention
The object of this invention is to provide that a kind of air-tightness is high, dried grain quality better, energy-saving and cost-reducing, environmental protection a kind of continous vacuum far infrared low temperature crop dryer.
