The specific embodiment

According to this structure, owing to make exhaust ports in open mode in the cooling procedure, the part of the cigarette that generates from coffee bean in the cooling procedure flows in the baking portion from discharge valve, by the oxidized decomposition of deodorizing catalyst and be discharged from outside the device, alleviate the dirt of scavenger fan by the amount that reduces the cigarette by exhaust outlet.

Embodiment

Below, with Fig. 1 to Fig. 5 embodiments of the invention are described.In addition, in Fig. 1 to Fig. 3 since with used same structural member in the past, put on same symbol, omission is described.

Action of the present invention is described.At first, uncap 2 is with the living beans input baking portion 4 of the coffee of ormal weight (as 60 grams).Then, the baking switch of making operation panel 3, beginning is to second electrothermal heater 8 and motor 18 energisings, and the deodorizing catalyst 14 that is heated by electrothermal heater 8 slowly heats up.Subsequently, deodorizing catalyst 14 reaches after the set point of temperature, switches on to first electrothermal heater 9.

After first electrothermal heater 9 is switched on, slowly heat up in the bottom of baking portion 4, and the living beans of coffee are stirred body 7 stirrings and are heated simultaneously.Then, first electrothermal heater 9 heats up first temperature sensor 11 that is arranged on dull and stereotyped 10 rapidly.

After temperature in the baking portion 4 rises, because the living beans of coffee contain the moisture of 12-13%, give birth to the initial steam that produces the beans from heated coffee, when temperature further raise, simultaneously generated the cigarette that be accompanied by foul smell with steam this moment.At this moment, entered the activate state because deodorizing catalyst 14 is accepted the radiation heat of second electrothermal heater 8, the steam of discharging from exhaust outlet 13, foul smell composition are by above-mentioned deodorizing catalyst 14 oxidation Decomposition and by odorlessization.

Then, after first temperature sensor 11 records the set point of temperature that is suitable for toasting,, the energising amount of first electrothermal heater 9 is controlled in order to keep set point of temperature after this.On the other hand, same when second temperature sensor 12 records set point of temperature, also the energising amount of second electrothermal heater 8 is controlled.In addition, about the control of energising amount, can adopt known in the past open and close control, position suitable mode such as control mutually.

By the energising amount of first electrothermal heater 9 and second electrothermal heater 8 is controlled, make baking portion 4 all keep desirable baking temperature.In this case, different with the living beans of coffee from the machine in the past of the temperature dispersion of the excessive radiation heat of specific direction acceptance, baking portion 4, whole being heated as being contained.

In addition, waste residue is peeled off from coffee bean in the process of toasting, but because of the crack that is formed in baking portion 4 bottoms waste residue is fallen, so the waste residue that is peeled off from coffee bean is recovered to the waste residue recipient 20 by tilt component 21 from the crack.

The growing amount of cigarette increased rapidly when coffee bean baking degree improved, and baking portion 4 reaches the state that is full of cigarette.Then, based on the sequential chart of Fig. 4, the situation when various piece is switched on is described.When the temperature of baking portion 4 reaches set point of temperature (as 200 ℃), drive scavenger fan 28, the cigarette that contains caffeine, paraffin etc. that will emit from baking portion 4, hot gas etc. are discharged outside the main body gradually.In the present embodiment, drive scavenger fan 28 when baking portion 4 reaches set point of temperature like this, but also can begin through stipulated time rear drive scavenger fan 28 in baking.

At this,,, thus, can prevent the influence that causes by heat for electric parts so also played the effect of cooling base 29 because scavenger fan 28 is arranged on the vertical direction upside of substrate 29.In addition, because cigarette also can not brought the impression of the product of inferior quality to the user by outside the discharger gradually.

Afterwards, make stirring body 7 keep operating state, stop the energising to first electrothermal heater 9 and second electrothermal heater 8, the further roasting coffee beans of waste heat of using baking portion 4 is to the stipulated time.This is referred to as follow-up baking, and the cigarette when discharging for reducing coffee bean drives cooling fan 23 after follow-up baking begins immediately.At this moment, because cooling fan 23 operates simultaneously with scavenger fan 28, produce flowing of air in the main body, because this air-flow, make waste residue at random in main body, institute not thinks carries out the running of cooling fan 23 and scavenger fan 28 simultaneously, after stopping scavenger fan 28 in a flash, come into operation again.

Through the stipulated time, after follow-up baking finishes, to solenoid 16 energisings.After solenoid 16 energisings, discharge valve 17 moves up and down, and as shown in Figure 5, opens because fall mouth 15, and coffee bean falls into cooling end 22 by falling mouth 15 under the stirring of stirring body 7.In addition, make the driving of cooling fan 23 stop the stipulated time when solenoid 16 energising, this is that the be cooled air-supply of fan 23 of fallen together waste residue dispels when preventing that coffee bean from falling into cooling end 22.

Then, the air-supply of cooling fan 23 is introduced hole 25 by the air of chest 24 sides, is blown into cooling end 22 from the peristome 26 that is arranged on cooling end 22 bottoms, the cooling coffee bean.And, during the cooling coffee bean, to solenoid 16 energisings, make discharge valve 17 be in open mode all the time, make baking portion 4 and cooling end 22 be in connected state with this.So, shown in the arrow of Fig. 5, along with the discharge of coffee bean, the part of the cigarette that generates from coffee bean the cigarette of discharging from baking portion, the cooling procedure flows in the baking portion 4, by exhaust outlet 13, by deodorizing catalyst 14 oxidation Decomposition on baking portion 4 tops and be discharged from outside the device.

On the other hand, because also drive scavenger fan 28 simultaneously, cigarette is deflated fan 28 attractions and discharges outside the main body.So body interior can not be full of cigarette, hot gas, also can prevent to separate out in the main body crystallization of caffeine etc. and the substrate part durability that greasy dirt causes descends, short circuit by adhering to.

Then, compared with the past because the part of cigarette is discharged from outside the main body by deodorizing catalyst 14 as mentioned above, the amount of the cigarette by scavenger fan reduces.Therefore, alleviate the dirt that adheres on the scavenger fan 28, can prevent the decline of fan performance.

In addition, the waste residue that peels off in nearly all bake process as previously mentioned, reclaimed by waste residue receiver 20 by tilt component 21 from the crack of the bottom of baking portion 4, but, few part still attached to the waste residue that falls into cooling end 22 on the coffee bean since the air-supply of cooling fan 23 from coffee bean, peeled off.At this, the waste residue that is peeled off is accommodated by chest 24 by the peristome 26 that is arranged on cooling end 22 bottoms, and therefore, coffee bean has obtained separating fully with waste residue.And because chest 24 is arranged on body interior, waste residue can not dispel the outside yet.

Cooling end 22 also plays the effect of keeping coffee bean, when taking out the coffee bean that toasted, draws the handle 27 of the main body side that is arranged on cooling end 22, cooling end 22 is pulled out get final product from main body 1.
