Description
Technical field
The utility model belongs to fruit and vegetable dryness process equipment field, particularly a kind of hot blast vacuum combination drying box.
Background technology
At present, although the heated-air drying processing mode efficiency of fruit and vegetable dryness manufacture field is improved, still there is uneven drying, drying efficiency in dry run is not very high problem.The mode that traditional heated-air drying equipment hot blast enters drying box has two kinds: a kind of is that hot blast enters from the both sides of drying box, goes out from the top of drying box.Can make like this in drying box, to be distributed in middle dry materials speed, and the dry materials speed being distributed in drying box top and bottom is comparatively slow, has occurred the phenomenon of uneven drying within identical drying time.Another kind is that hot blast enters from the bottom of drying box, by hot blast uniform distributor, pass through material again, then go out from the top of drying box, this air inlet mode makes the dry materials speed be distributed in bottom drying box, the dry materials speed being distributed in drying box top is slower, because it is higher to be distributed in the hot blast temperature that the material bottom drying box obtains, humidity is less, the moisture that hot blast is taken away is more, when hot blast is through being distributed in the material at drying box top, hot blast temperature is lower, humidity is also larger, the moisture taken away is less, so just there is uneven drying phenomenon, for the shortcoming that the air inlet mode overcoming above-mentioned two kinds of heated-air dryings is brought, the utility model proposes a kind of hot blast vacuum combination drying box.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of hot blast vacuum combination drying box, the high and uniform drying of drying efficiency.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of hot blast vacuum combination drying box, comprise material disc 5, hot blast wind-distributing pipe 3, materials vehicle 4, hot blast wind-distributing pipe joint 2, sealing ring 8, hot-water line dish 1 and hot blast wind chamber 7, wherein materials vehicle 4 is positioned at case, bottom is provided with materials vehicle wheel 6, material disc 5, hot blast wind-distributing pipe 3 and hot-water line dish 1 are installed in materials vehicle 4, hot-water line dish 1 spirals and is arranged to sandwich construction, the top of every layer of hot-water line dish 1 arranges a material disc 5, the below of every layer of hot-water line dish 1 arranges a hot blast wind-distributing pipe 3, hot blast wind-distributing pipe 3 has the exhaust vent of material disc 5 downward, the two ends of each hot blast wind-distributing pipe 3 are all communicated with hot blast wind chamber 7 by hot blast wind-distributing pipe joint 2.
The one-sided enabling of described drying box.
Trying to get to the heart of a matter of described material disc 5 is 10 object screen clothes.
Described hot blast wind-distributing pipe 3 has vertically three discharge air holes, often discharging air holes has several.
When described hot blast wind-distributing pipe 3 length is more than 2m, often discharge in air holes, from pipe two ends to centre, the aperture of exhaust vent increases gradually.
Described hot blast wind-distributing pipe joint 2 is connected by male and female groove with the chamber wall in hot blast wind chamber 7.
Described sealing ring 8 is for hermetically drying case chamber door, and it is nitrile rubber sealing ring, and cross sectional shape is semicircle, and straight warp is 0.3 times of tank thickness.
Compared with prior art, the vacuum hot-air dry case that the utility model provides has the high feature of drying efficiency, because hot blast directly blows to material by hot blast wind-distributing pipe hole, and dry materials speed.And owing to each material disc there being uniform hot blast wind-distributing pipe, the material in drying box can obtain the identical hot blast of humidity, so the drying in dry run of the material in each material disc is more even.
Accompanying drawing explanation
Fig. 1 is the front view of a kind of highly effective drying uniform vacuum hot-air dry case internal structure.
Fig. 2 is the top view of a kind of highly effective drying uniform vacuum hot-air dry case internal structure.
Fig. 3 is the right view of a kind of highly effective drying uniform vacuum hot-air dry case internal structure.
Detailed description of the invention
Embodiment of the present utility model is described in detail below in conjunction with drawings and Examples.
As Fig. 1, shown in Fig. 2 and Fig. 3, a kind of hot blast vacuum combination drying box, comprise material disc 5, hot blast wind-distributing pipe 3, materials vehicle 4, hot blast wind-distributing pipe joint 2, sealing ring 8, hot-water line dish 1 and hot blast wind chamber 7, wherein materials vehicle 4 is positioned at case, bottom is provided with materials vehicle wheel 6, material disc 5, hot blast wind-distributing pipe 3 and hot-water line dish 1 are installed in materials vehicle 4, hot-water line dish 1 spirals and is arranged to sandwich construction, the top of every layer of hot-water line dish 1 arranges a material disc 5, the below of every layer of hot-water line dish 1 arranges a hot blast wind-distributing pipe 3, hot blast wind-distributing pipe 3 has the exhaust vent of material disc 5 downward, the two ends of each hot blast wind-distributing pipe 3 are all communicated with hot blast wind chamber 7 by hot blast wind-distributing pipe joint 2.
Can find out there is hot-blast outlet at the top of drying box, material disc 5 is placed on materials vehicle 4, and is positioned at the top of every layer of hot-water coil pipe 1, the below of hot blast wind-distributing pipe 3, is placed with and needs dry material in material disc.Hot blast wind-distributing pipe 3 is fixed on materials vehicle 4, and the exhaust vent on hot blast wind-distributing pipe 3 is downwards just to material disc 5, and make hot blast directly blow to material, two is connected with hot blast wind-distributing pipe joint 2, and hot blast wind-distributing pipe joint 2 and hot blast wind chamber 7 are connected by male and female groove.Sealing ring 8 is contained on drying box opening tank wall, for the sealing of chamber door and drying box.Hot-water line dish 1 to be fixed on materials vehicle 4 and to be connected with extraneous hot water supply line by stainless steel lathe dog, and materials vehicle wheel 6 is contained in the bottom of materials vehicle 4, for the movement of materials vehicle.Hot blast wind chamber 7 is positioned at bottom and the both sides of drying box inwall, leaves certain space, for being delivered to by hot blast in each hot blast wind-distributing pipe 3.
Use procedure of the present utility model:
Will dry material be laid in uniformly try to get to the heart of a matter be 10 eye mesh screens material disc in, close chamber door.First carry out heated-air drying, open hot blast that hot blast terminal valve makes to reach uniform temperature enters drying box bottom by hot-wind inlet, it is inner that hot blast wind chamber 7 again by being interconnected arrives hot blast wind-distributing pipe, hot blast is by the exhaust vent on hot blast wind-distributing pipe 3, directly hot blast is blowed to material, utilize the thermal convection current between hot blast and material, heat transfer, the temperature of hot blast is passed to material by heat radiation, after material obtains temperature, the moisture on its surface is constantly vaporized and is diffused in surrounding medium, then the moisture contained by material shifts to surface gradually from inside, material moisture is declined.Hot blast in drying box air temperature passes to the rising of material for temperature of charge and the evaporation of moisture, part heat is got rid of through hot-blast outlet with hot blast, hot blast has taken away the moisture that material evaporates simultaneously, and hot water is conducted heat to material by hot-water coil pipe simultaneously.The hot-blast outlet had from the inside of drying box by box top after hot blast and material carry out mass-and heat-transfer is flowed out, close hot blast terminal valve when carrying out vacuum drying, the vacuum lead that the pipeline connected by hot-blast outlet two has carries out vacuumizing drying.
