Abstract

The utility model provides a vertex hot air drying machine, which is used for drying products such as tea, etc. The drying machine is composed of a thermal source (toaster) vertical type channel drying box, drying disks arranged inside the drying box, a helical air heater with automatic air intake, etc. Under the action of the heat source, air inside the helical air heater is heated, uniformly enters the drying box for gradually taking away moisture inside drying substances, and is discharged via a moisture discharge drum. The helical air heater can automatically suck cold air simultaneously. Because a helical tube is long for prolonging the heating time, the machine has high thermal efficiency. The machine can be conveniently moved to a tea zone for processing fresh tea leaves and can provide a good drying apparatus for making good tea.

Description

Vertex hot air drier

The utility model belongs to oven, particularly a kind of cyclone type air flow dryer that is used for drying tea leaves.

In each excellent tea tea making process,, behind the stir-fry tea, further remove the moisture content of tealeaves with dryer to drying tea leaves in order to reduce the fragmentation of tealeaves.Electric dryer and small-sized hot blast drawer type dryer can be used for tea curing.But these two kinds of dryers all will be used the air blast forced ventilation, and the drying cavity moisture is very big, and the thermal efficiency is not high, and cost is also bigger, is difficult for satisfying the needs of tea making.

Because some mountain area does not have electricity, perhaps the electricity charge too high (2 yuan of every degree) bring a lot of inconvenience to the famous-brand and high-quality tea of mountain area system.The purpose of this utility model provides and a kind ofly acts as a fuel with coal or firewood, oil, gas etc., cool exterior air directly can be sucked, and heats on thermal source, is taken away the cyclone type air flow dryer of moisture content on the tealeaves again by hot gas.

The technical solution of the utility model is: on thermal source (1), spirality fan heater (2) is housed, adorning on the fan heater (2) and adorning in vertical tunnel drying baker (4) drying baker on tubaeform diffuser (3), the diffuser (3), stacking multilayer drip pan (5), on the upper top cover of drying baker (6), hydrofuge tube (7) is housed, and the both sides in the drying baker bottom are provided with drip pan and prop up support mechanism (15).Various mentioned components all is contained in the stand frame (8).

The structure of spirality fan heater (2) is, air inlet duct (9) is a spiral line type, and there is vertical discharge pipe (10) at the middle part, scribbles far infrared air heat coating on the inwall of air inlet duct (9) and discharge pipe (10), on the shell of air inlet duct (9) and discharge pipe (10), scribble insulation material.

The casing of vertical tunnel drying baker (11) is vertical tunnel type casing.

In order to guarantee that the drip pan landing time does not produce impact, in bottom, drying baker casing two sides, is provided with drip pan and props up support mechanism (15).It is to be made of little fixing (16) outside the supporting bar of adorning in bar cover (17), the bar cover (18) that can rotate in the bar cover, the bar cover that drip pan props up support mechanism, and little axle (16) is contained in the axle bed (19) of casing side, and little axle can rotate in axle bed.Operation supporting bar (18) is when little axle (16) swing rotation, and the bar cover drives little axle and and then rotates in axle bed.The lever (20) of supporting bar (18) afterbody below the time (as Fig. 4), the hook of supporting bar end just withstands on time both sides, bottom drip pan bottom surface, at this moment can take out the bottom drip pan, top drip pan does not fall under supporting bar supports.After the bottom drip pan takes out, rotate supporting bar around little axle again, inferior bottom drip pan is slowly put into the bottom, at this moment lever (20) rotates supporting bar up again, makes the hook of supporting bar front end throw off drip pan.Rotate supporting bar around little axle again, make lever (20) get back to the below again, the supporting bar front end is in again under time bottom drip pan, like this, so repeatedly, just can put and take out drip pan into.

The utility model is strictly a kind of compact conformation, regulation and control conveniently, and the oven dry machinery that the thermal efficiency is high not only can be dried tealeaves but also can be dried other products such as Chinese prickly ash, peanut, auricularia auriculajudae.

Fig. 3 is the B-B cutaway view of Fig. 1.

Fig. 4 is that the C of Fig. 2 is to view.

Embodiment: in the framework that four root posts surround, lower floor is thermal source (1), thermal source (1) adopts honeycomb briquette stove, can lay spirality fan heater (2) on the thermal source, on the vertical discharge pipe (10) of fan heater, overlapping tubaeform diffuser (3), adorn vertical tunnel drying baker (4) on it, in the drying baker, stacking multilayer drying tray (5), on the upper top cover of drying baker (6), hydrofuge pump bowl (7) is housed.At drying baker two downsides, be provided with drip pan and prop up support mechanism.The casing (11) of vertical tunnel drying baker (4) rolls into galvanized iron sheet, and the top of vertical tunnel type baking oven has drip pan and puts into mouthful (12), and the bottom has drip pan conveying end (13), and outer surface scribbles insulation material.The bottom surface of drip pan (5) is a sieve plate, is furnished with passage (14) on the plate.Below, with oven dry tealeaves is example, narrates its operation principle: the tealeaves that will fry after the shaping is placed in the drip pan, and the drip pan of drying upper box part is put into mouthful (12), drip pan satisfied time put into baking oven again, close and put entrance door, under the thermal source effect, the air of spirality fan heater (2) is heated, and air by vertical discharge pipe (10) upwards, through diffuser (3) diffusion reduction of speed, enter baking oven equably, layer strip is walked the moisture content in the tealeaves then, is discharged by the hydrofuge tube.Because the leafing thermal source is near down, the temperature height, so oven dry at first, oven dry one dish is taken a dish away, puts into a dish at upper inlet again, like this, just can continuous operation.Hot blast was made progress the heating, drying case by discharge pipe when, the air inlet duct of spirality fan heater (9) just entered cold air, because helix tube is longer than straight tube, thereby had increased the heat time heating time of air, had improved the thermal efficiency of this machine.Heat insulation coating of this machine and far infrared coating have also improved thermal effect.

The utility model also is convenient to move, and can easily this machine be moved on to the processing of tea district, greatly facilitates the user and makes well-known tea.
