Ginger flash baking device
Technical field
The present invention relates to a kind of drying unit, be specifically related to a kind of ginger flash baking device.
Background technology
China is one of country that ginger output is maximum in the world, and fresh ginger stores easy going rotten, and elephant skin are shrivelled rotten, are difficult for long preservation.Ginger is processed into ginger slice or ginger grain, and then dries preservation, not only solved the storage and the transportation problem of ginger, enriched ginger products market simultaneously, edible also convenient.
Traditional ginger drying mode is the hot air convection heating, drying; And this mode is very improper to the oven dry of ginger; Being that drying rate is slow, drying time is long on the one hand, is ginger variable color easily in drying course on the other hand, also needs special increasing to protect the look operation; Otherwise can not obtain the excellent ginger oven dry product of golden yellow color, production cost is higher.
Therefore, need traditional ginger drying mode be improved, design the device that is applicable to the ginger oven dry,, save production cost simultaneously to improve ginger drying efficiency and ginger oven dry product quality.
Summary of the invention
In view of this, the invention provides a kind of ginger flash baking device, ability flash baking ginger improves the ginger drying efficiency, can prevent the ginger variable color simultaneously, obtains the excellent ginger oven dry of the no sulphur product of golden yellow color.
Ginger flash baking device of the present invention comprises fuselage, fluid bed and runs through the ginger foraminous conveyer of fuselage; Said fuselage is divided into the short-wave infrared thermal treatment zone, medium wave Infrared Heating district and Far-infrared Heating district successively; The top is provided with short-wave infrared heating tube group in the said short-wave infrared thermal treatment zone; The top is provided with medium wave infrared heating pipe group in the medium wave Infrared Heating district; The top is provided with the far-infrared heating tube group in the Far-infrared Heating district, and top, said Far-infrared Heating district has air inlet, and the short-wave infrared thermal treatment zone and top, medium wave Infrared Heating district have air outlet; Said fluid bed comprises lathe bed and blower fan, and blower fan is communicated with lathe bed, has blowhole on the lathe bed, and the lathe bed of said fluid bed is positioned at the short-wave infrared thermal treatment zone and medium wave Infrared Heating district and near ginger foraminous conveyer below.
Further; During said ginger foraminous conveyer is divided into following three layers; Upper strata ginger transmission net tape leader is feed end and stretches out outside the fuselage that the afterbody of upper strata ginger foraminous conveyer is connected with middle level ginger transmission net tape leader, and the afterbody of middle level ginger foraminous conveyer is connected with lower floor ginger transmission net tape leader; The afterbody of lower floor's ginger foraminous conveyer is discharge end and stretches out outside the fuselage that the lathe bed of said fluid bed is near upper strata ginger foraminous conveyer below;
Further, said middle level ginger transmission net tape leader and lower floor's ginger transmission net tape leader are respectively equipped with striker plate.
Beneficial effect of the present invention is: ginger flash baking device of the present invention has comprised infrared heating system, fluid bed and hot air circulating system, when ginger slice or ginger grain are carried on the ginger foraminous conveyer, through the infrared Fast Heating of intermediate waves; The fluid bed of below is toward ginger foraminous conveyer up-draught simultaneously, and the wind direction major part is the direction of advancing to the ginger foraminous conveyer, makes ginger slice or ginger grain be the state that seethes up and down; Between or one group be that counter blow is seethed with reinforcement; Therefore, ginger is heated rapidly and is even, the free moisture rapid evaporation of ginger; Again through Far-infrared Heating and heat-wind circulate drying, guarantee that the last moisture of ginger reaches requirement at last; In addition, intermediate waves is infrared can be to the ginger enzyme removal protecting color that completes, thereby prevents the ginger variable color, guarantees to obtain the excellent ginger oven dry of the no sulphur product of golden yellow color.
The mode that the present invention adopts Infrared Heating to combine with fluid bed and hot air circulation; Improved the ginger drying efficiency; Reached the purpose of flash baking ginger, the present invention simultaneously need not to protect look, also can prevent the ginger variable color; Obtain the excellent ginger oven dry of the no sulphur product of golden yellow color, practiced thrift production cost.This device also can be used for the rapid draing of other agricultural product, is particularly suitable for the drying that completes of irregular light material such as agricultural product such as honeysuckle or tealeaves.
Description of drawings
In order to make the object of the invention, technical scheme and advantage clearer, will combine accompanying drawing that the present invention is made further detailed description below, wherein:
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below will carry out detailed description to the preferred embodiments of the present invention with reference to accompanying drawing.
Fig. 1 is structural representation of the present invention, and is as shown in the figure, and ginger flash baking device of the present invention comprises fuselage 1, fluid bed and runs through the ginger foraminous conveyer 3 of fuselage 1; Said fuselage 1 is divided into the short-wave infrared thermal treatment zone, medium wave Infrared Heating district and Far-infrared Heating district successively; The top is provided with short-wave infrared heating tube group 4 in the said short-wave infrared thermal treatment zone; The top is provided with medium wave infrared heating pipe group 5 in the medium wave Infrared Heating district; The top is provided with far-infrared heating tube group 6 in the Far-infrared Heating district, and top, said Far-infrared Heating district has air inlet 7, and the short-wave infrared thermal treatment zone and top, medium wave Infrared Heating district have air outlet 8; Said fluid bed comprises lathe bed 2 and blower fan 9, and blower fan 9 is communicated with lathe bed 2, has blowhole on the lathe bed 2, and the lathe bed 2 of said fluid bed is positioned at the short-wave infrared thermal treatment zone and medium wave Infrared Heating district and near ginger foraminous conveyer 3 belows.
As further improvement of the present invention; During said ginger foraminous conveyer 3 is divided into following three layers; Upper strata ginger transmission net tape leader is feed end 10 and stretches out outside the fuselage 1 that the afterbody of upper strata ginger foraminous conveyer is connected with middle level ginger transmission net tape leader, and the afterbody of middle level ginger foraminous conveyer is connected with lower floor ginger transmission net tape leader; The afterbody of lower floor's ginger foraminous conveyer is discharge end 11 and stretches out outside the fuselage 1 that the lathe bed 2 of said fluid bed is near upper strata ginger foraminous conveyer below; During ginger foraminous conveyer 3 is divided into following three layers is in order to increase the fed distance of ginger in fuselage 1, to make full use of heat energy; In the present embodiment, said middle level ginger transmission net tape leader and lower floor's ginger transmission net tape leader are respectively equipped with striker plate 12.
