Embodiment

Specific embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.It should be appreciated that herein Described embodiment is merely to illustrate and explained the utility model, is not limited to the utility model.

In the utility model, in the case where not making opposite explanation, " upper and lower, top, bottom, forward and backward " etc. is included in term In the noun of locality only represent orientation of the term under normal service condition, or be skilled artisan understands that be commonly called as, and It is not construed as the limitation to the term.

The utility model provides a kind of high-efficient hot air furnace, as depicted in figs. 1 and 2, including：Housing 1, the inside of housing 1 Formed with cavity, cavity is made up of drying chamber and two vented cavities 2, and two vented cavities 2 are located at both ends and the drying of drying chamber Formed with through hole between chamber and vented cavity 2, drying chamber is infundibulate wide at the top and narrow at the bottom；Wherein, set in the side wall of a vented cavity 2 Air inlet 8 is equipped with, air outlet 7 is provided with the side wall of another vented cavity 2；

Wherein, multiple heating grooves 3 and multiple holding tanks 4 for being used to accommodate cereal are arranged at intervals with drying chamber；Adjacent Holding tank 4 on the wall of heating groove 3 with being provided with multiple air vents；Vertical direction is provided with multiple heating lists in heating groove 3 First 5 (such as heater strips), also, direction of the power of heating unit 5 from air intake to air-out is successively decreased successively.

The operation principle of above-mentioned high-efficient hot air furnace is as follows：First, cereal is placed in holding tank 4；Then, heating is started The power supply of unit 5 so cause heating unit 5 start working.Wherein, in the course of the work, cold air is from air intake for heating unit 5 Mouth 8 enters in the first vented cavity 2, then (passes sequentially through air vent and then in drying chamber by through hole by heating groove 3 and accommodates Groove 4), due to air expand with heat and contract with cold so that cause hot-air the second vented cavity 2 is entered by through hole, finally by air outlet 7 Discharge the hot-air containing large quantity of moisture.The funnel shaped drying chamber enable cereal fully, rapidly air intake and air-out, from And cause cereal that there is excellent rate of drying.Meanwhile direction of the power of heating unit 5 from air intake to air-out is successively decreased successively, It can ensure that cereal is essentially identical in each local heating-up temperature, and then cause the moisture content basic one of dried cereal Cause, so as to reduce the preservation difficulty of cereal.

In the present embodiment, in order to be further ensured that cereal is essentially identical in each local heating-up temperature, it is preferable that High-efficient hot air furnace is additionally provided with temperature control controller and multiple temperature sensors 10, and temperature sensor 10 is arranged at the interior of heating groove 3 The wall temperature of groove 3 is heated in side wall with detection, heating unit 5 is each independently connected with temperature sensor 10 with temperature control controller； Wherein, the temperature signal collected is sent to temperature control controller by temperature sensor 10, and temperature control controller can be believed according to temperature Number regulation heating unit 5 power so that heating groove 3 direction of the wall temperature along air intake to air-out be consistent.Thus, temperature control Controller can effectively realize the power of control heating unit 5 by temperature sensor 10, so that cereal is in each office The heating-up temperature in portion is of substantially equal, and then causes the moisture content of paddy seed to keep basically identical.

Meanwhile in the utility model, the particular location of air inlet 8 and air outlet 7 can select in wide scope, be Allow air to form most excellent circulation in housing 1, it is preferable that air inlet 8 is arranged on the rear end face of housing 1, is gone out Air port 7 is arranged on the front end face of housing 1.Thus, air just can be circulated along the fore-and-aft direction of housing 1, so that Obtain cereal to be sufficiently carried out contacting with carrying out with air, and the hot-air containing moisture is discharged in time.

In order to further improve circulation of the air in housing 1, it is preferable that air inlet 8 is arranged at the rear end face of housing 1 Bottom, air outlet 7 are arranged at the top of the front end face of housing 1.Because the density of cold air is more than the density of hot-air, then will Air inlet 8 is arranged on bottom, and air outlet 7 is arranged on top, just can further promote the inlet and outlet of air, so as to improve Drying effect.

On the basis of above-mentioned embodiment, in order to further improve the inlet and outlet of air, it is preferable that drying chamber Bottom is provided with exhausting groove 9, and extractor fan (such as fan) is provided with exhausting groove 9, thus, is promoted using the twitch of extractor fan The circulation of air, improve drying effect.

In addition, prevent impurity Polluted grains in the drying process, it is preferable that the top of holding tank 4 is provided with flip top cover 6。

Finally, it is contemplated that for cereal in the case where moisture content is larger, the surface of cereal has bacterium, it is preferable that holding tank 4 And/or it is provided with ultraviolet generater in heating groove 3；Cereal can so be sterilized by ultraviolet generater, so as to Improve the storage effect of cereal.

Preferred embodiment of the present utility model, still, the utility model and unlimited is described in detail above in association with accompanying drawing Detail in above-mentioned embodiment, can be to skill of the present utility model in range of the technology design of the present utility model Art scheme carries out a variety of simple variants, and these simple variants belong to the scope of protection of the utility model.

It is further to note that each particular technique feature described in above-mentioned embodiment, in not lance In the case of shield, it can be combined by any suitable means, in order to avoid unnecessary repetition, the utility model is to each The possible combination of kind no longer separately illustrates.
