The madial wall of staving offsets, and described supporting plate vertically runs through multiple air-vents.
In the presence of 0 shape circle, make to form sealing between supporting plate and the madial wall of staving, so that hot gas is completely by saturating
Stomata is discharged.In actual product, the aperture of air-vent will not be very big, so that drying substantially the leading by supporting plate of food
Heat is completed, and so just makes operating personnel be more prone to control the temperature around food, so as to further avoid food excessive dehydration.
In the above-mentioned equipment for dried foods, described bung is connected by helicitic texture with staving, bung
Roof is provided with for coordinating with instrument so that instrument can drive the rotating hole of bung rotation, and rotating hole is blind hole, described
Rotating hole has two and along the circumferential uniform of bung.
Just supporting plate can be removed or placed into staving by rotating bung, had the advantages that easy to use.
Alternatively, in the above-mentioned equipment for dried foods, on the upper end lateral wall of described staving
With annular convex shoulder, magnet is cased with staving, magnet is located between bung and annular convex shoulder and the magnet is mutually fixed with bung, institute
The annular convex shoulder stated is made up of permeability magnetic material, and the lower surface of magnet offsets with the upper surface of annular convex shoulder.
Bung is detachably fixed by magnet with staving, is had the advantages that easy to use.
In the above-mentioned equipment for dried foods, the upper end of described screw rod is arranged and is fixed with handwheel.
By setting handwheel, operator is facilitated to rotate screw rod.
Compared with prior art, this equipment for being used for dried foods has advantages below:
1st, during food baking, screw rod is rotated at regular intervals makes supporting plate constantly away from electric heater, so that
Contained heat in the hot gas contacted with food is constantly reduced, so that the efficiency of food baking is constantly reduced, it is more to reserve
Time for operating personnel observe, be then prevented effectively from food excessive dehydration.
2nd, through hole is set by the bottom of groove, the steam that will can have both been produced during food baking is comparatively fast and food
Depart from, (after drying terminates, partly the steam in staving can form the globule simultaneously for the globule discharge that will can assemble in groove again
Drop into groove), so as to be prevented effectively from the influence to next food baking.
3rd, in the presence of 0 shape circle, make to form sealing between supporting plate and the madial wall of staving, so that hot gas passes through completely
Air-vent is discharged.In actual product, the aperture of air-vent will not be very big, so that the drying of food is substantially by supporting plate
Heat conduction is completed, and so just makes operating personnel be more prone to control the temperature around food, so as to further avoid food from excessively taking off
Water.
