Abstract

The utility model relates to a spiral hot-air drying furnace for drying macadamia nut, which consists of a furnace body, an air blower, a heater, a ventilation port, an exhaust port, a material feeding opening and a material discharging opening. The axial center of a hearth is provided with a spiral raiser which is linked with an electric motor through a gearbox; an insulation sleeve which is fixedly connected with the bottom wall of the hearth through supporting columns and arranged higher than the furnace wall separates the raiser from the hearth; the lower part of the hearth is provided with an inverted cone-shaped trough; the upper part thereof is provided with a cone-shaped shield which is fixedly connected with the inner wall of the furnace through supporting bars. When the furnace is used, the temperature of the hot air, the rotating speed of the raiser and the drying time can be flexibly controlled; the extent and speed of dehydrating the macadamia nut can be accurately controlled; and the macadamia nut arranged in the furnace can be lifted to the top from the bottom and then slide down so as to be overturned in a cycling way, thereby preventing the bursting due to excessively rapid dehydration and fully ensuring the quality of the dried macadamia nut. Therefore, the utility model is an ideal macadamia nut drying device.

Description

Queensland nut spiral hot-air drying stove

Technical field

The utility model belongs to heated-air drying machinery, is a kind of spiral hot-air drying stove that is suitable for drying Queensland nut.

Background technology

Existing general heated-air drying equipment combines by parts such as drier, air blast, heater, temperature controllers, after material is put into drying box, after heating, the cold air that electro-heat equipment is sent air blast here enters drying box, hot-air is the heat transferred material, make the material contained humidity be vaporized into steam and discharge drier with air-flow, the dehydration of material drying reaches required moisture content standard; Use this class heated-air drying equipment, can avoid traditional material airing to dehydrate the drawback that is limited by weather effect, but its defective is arranged also: it can't satisfy some material specially dehydrates requirement, drying as large batch of Queensland nut, need under various baking temperatures, continue thermal dehydration equably, otherwise can cause nut dehydration too fast and burst, and then influence the quality of Queensland nut, common heated-air drying equipment can't reach.

The utility model content

The purpose of this utility model provides a kind of Queensland nut spiral hot-air drying stove, can effectively solve existing heated-air drying equipment and can't continue the problem of dry Queensland nut in enormous quantities equably, guarantees that unlikely dehydration is too fast and bursts.

The utility model is realized above-mentioned purpose by following technical measures:

A kind of Queensland nut spiral hot-air drying stove, form jointly by body of heater, air blast, heating element, ventilating opening, exhaust outlet, charging aperture, discharging opening parts, it is characterized in that: the burner hearth shaft core position is equipped with the spiral lifter that links through reduction box and motor, by pillar and burner hearth diapire Joint and the spacer that is higher than the furnace wall spiral lifter is separated with burner hearth, lower furnace portion has the reverse frustoconic hopper, and upper furnace has the truncated cone-shaped housing by support bar and inboard wall of burner hearth Joint.

The screw rod of described spiral lifter is higher than spacer.

Described spacer break-through housing is also closely affixed with the central circle of housing hole inner edge.

Many blast pipes are arranged on the described housing.

A plurality of air vents are arranged, discharging opening and a slice slide plate on the described trough sidewalls.

Described swash plate connects discharging opening and fire door.

The utlity model has following advantage and good effect:

Use this stove owing to can control the temperature of hot blast, the rotating speed and the drying time of lifter neatly, just can accurately control the degree of dehydration and the dewatering speed of Queensland nut, put the nut in the stove into, can rise to from furnace bottom and push up under the landing again, stirring circulates, having avoided too fast dehydration to cause and burst, fully guaranteed dried nut quality, is a kind of comparatively desirable Queensland nut drying equipment.

Fig. 2 is a stove of the present utility model bottom schematic cross section.

Fig. 3 is a stove of the present utility model top schematic cross section.

The specific embodiment

Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail.

As shown in the figure, the thorax shaft core position is equipped with a cover spiral lifter 5 in the dry body of heater 6 of cylindrical shape, and the screw rod lower end is passed furnace bottom and linked through reduction box 22 and motor 21, and the bearing 10 on screw rod upper end and the furnace roof cover plate 9 links; Cylindrical spacer 4 separates spiral lifter and burner hearth, and the spacer lower end is fixedly linked by 4 pillars 23 and furnace bottom; The reverse frustoconic hopper 15 that lower furnace portion has an opening to make progress is connected with a plurality of air vents 3 on the trough sidewalls, also have a discharging opening 17 and a slice slide plate 16 of slippage up and down on the trough sidewalls; End housing one side has air inlet 24 under the drying oven, and with heating element 1 and air blast 2 UNICOMs, the opposite side furnace wall has fire door 18, is associated with discharging swash plate 20 between fire door and discharging opening; The truncated cone-shaped housing 8 that one hollow is arranged in the burner hearth of drying oven upper end, the housing lower edge is fixedly connected by many support bars 7 and inboard wall of burner hearth, attaching has many blast pipes 12 on the housing, the circular hole inner edge of housing central authorities closely is fixedly connected with the spacer outer wall that passes circular hole, and the strut 11 and the furnace roof cover plate that connect on the cover cap link; The round hole inner edge of housing central authorities is closely affixed with the spacer outer wall that passes round hole.Have charging aperture 14 and door closure 13 on the drying oven upper portion side wall, body of heater is supported by support 19.

When using this drying oven, need only open door closure 13, Queensland nut to be dried is poured in the stove by charging aperture 14, close door closure, actuating motor drives the spiral lifter and promotes by trough sidewalls and tumble into nut after speed change, open air blast 2 and heating element 1 simultaneously, allow hot blast enter burner hearth, increase fire box temperature through air inlet and air vent; The nut that is promoted by the spiral lifter with the rotation of screw rod ceaselessly, stir equably, when promoting near furnace roof, owing to there is not the fence of spacer, nut drops to naturally on the housing and along the slit of housing and furnace wall and drops in burner hearth and the hopper, the spiral lifter that is rotated once more then stirs and promotes, circulate endlessly so repeatedly, the nut contained humidity is discharged out of the furnace by the blast pipe on the cover cap by hot blast heating vaporization back in the thorax.After reaching dry the requirement, close down air blast, heating element and motor, take out out slide plate by fire door and emit outside the stove through the discharging swash plate by discharging opening by nut.
