Further, for the running status of monitor in real time drying machine, can process in time after breaking down.Grain discharging section 340 in the present embodiment also includes the detector 342 for detecting moisture and baking temperature.Described detector 342 is on-line detector 342, is fixed on drying machine body 110, is positioned at the lower section of delivery device 341.
Moisture in the present embodiment and baking temperature on-line detector 342, proportioning valve 323 can commercially be buied, and generating far infrared rays 321 adopts ordinary carbon steel to be made.
During crop seed many field coordination drying machine provided by the invention work, the tower top that seed is risen to drying machine by elevator 410 falls into drying machine, after drying machine is filled, opens belt feeder 420, delivery device 341 under air-introduced machine 520, elevator 410, machine in order.nullSeed is just completely dependent on deadweight in drying machine，Order is sluggish flow downwards，It is scattering under machine on belt feeder 420，The seed discharged by belt feeder under machine 420 sends elevator 410 back to，Tower top is risen to again by elevator 410，Realize cyclic drying，Meanwhile，Flue gas in air stove 210，Under the gravitation of air-introduced machine 520，After flowing through heat exchanger 220，Enter generating far infrared rays 321，The part of waste heat in far infrared generating means 321, it carried changes into far-infrared radiation energy，It is supplied to the seed of flowing，Owing to generating far infrared rays 321 designs in drying machine，Around surrounded by the seed of loose flowing，So，The global radiation ascent of seed in drying machine is equal to 1 by generating far infrared rays 321，Namely the radiant energy that the appearance of generating far infrared rays 321 produces can all by neutron absorption，It is converted into the interior energy of seed，Again because drying and have employed inverse mixed flow air inducing drying mode，Air pressure in aerofluxus angle box 332 is inevitable far below the air pressure in delay section 310，What thus make blood pressure lowering expansion drying section 320 naturally form bigger air pressure difference up and down，Obviously，Seed is in the blood pressure lowering expansion drying section 320 of full infrared thermal radiation，Experience is the process with the continuous blood pressure lowering that flows downward.In this process, during the saturation pressure crossing corresponding to the surface of the seed temperature when pressure is low, Free water on high humidity seed will consume the interior of seed can there is flash distillation, so that the temperature of seed reduces rapidly, thus achieve high humidity seed blood pressure lowering expansion drying in far-infrared radiation field, both significantly enhanced dry run, in turn ensure that the baking temperature of seed self does not transfinite, also utilize far infrared adjustment effect, improve seed tissue function, improve drying quality.After entering drying machine due to seed, be completely dependent on conducting oneself with dignity flowing continuously, so, when seed is from the inflow of blood pressure lowering expansion drying section against mixed flow air inducing dryer section 330, constantly replaced by the aerofluxus angle box 332 of upper and lower Heterogeneous Permutation and the guide effect of flow inlet angle box 331 and change fluidised form, make seed uniform wind-engaging in all directions, not only increase the uniformity of seed drying, simultaneously, without producing mechanical damage and remaining seed in drying machine, the versatility of drying machine is greatly improved, adapts to the dry of all kinds of crop seed and granule materials.
Should be understood that; the application of the present invention is not limited to above-mentioned citing; for those of ordinary skills; can be improved according to the above description or be converted; such as; common/usual replacement etc. to each component in the present invention, all these improve and convert the protection domain that all should belong to claims of the present invention.
