DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a bean roasting method and a roasting machine mainly used for roasting coffee beans.

<Prior Art> A coffee bean roasting machine is a hot air type that uses hot air to roast coffee beans.

A hot air roaster has a bean roaster for storing coffee beans in a roasting chamber through which hot air flows, and the coffee beans placed in the bean roaster are heated and roasted by the hot air flowing through the bean roaster. It is configured to do this.

Recently, a far-infrared roasting machine that uses far-infrared rays to roast coffee beans has been invented.

A far-infrared roasting machine is equipped with a bean roaster for storing coffee beans in a roasting chamber through which hot air flows, a far-infrared radiation material is attached to the bean roaster, and the far-infrared radiation material is heated with hot air. It is configured to emit far-infrared rays, and the coffee beans placed in the bean roaster are heated and roasted by the far-infrared rays emitted by the far-infrared radiating material and hot air flowing through the bean roaster.

Note that when a far-infrared roaster is used to roast coffee beans, the coffee has a mellow and characteristic taste.

Therefore, recently, coffee beans roasted with a hot-air roaster and coffee beans roasted with a far-infrared roaster are on sale.

<Problems to be Solved by the Invention> However, the hot air roasting machine is a dedicated hot air roasting machine, and although it can perform hot air roasting, it cannot perform far infrared roasting.

If a hot-air roasting machine is to be modified to a far-infrared roaster, the hot-air brewer installed in the roasting room must be replaced with a far-infrared brewer equipped with far-infrared radiating material. It takes a lot of effort.

That is, it is very difficult to perform far-infrared roasting using an existing hot air roasting machine.

Furthermore, in order to restore a hot-air roaster that has been modified to a far-infrared roaster to a hot-air roaster, the brewer must be replaced again, which requires a lot of effort.

That is, it is very difficult to temporarily use a hot air roaster as a far-infrared roaster.

The beans in the stand are heated by the hot air that flows through the stand, and the beans are roasted by the hot air flowing through the stand and the far infrared rays emitted by the far infrared radiation balls in the stand, performing far-infrared roasting. It will be done.

Furthermore, in the bean roasting machine of the present invention, when a far-infrared radiation ball is placed together with the beans in the brewer of the hot-air roasting machine, the bean roasting method of the present invention is carried out. Roasting is performed, and unless a far-infrared radiation ball is placed in the brewer of hot-air roasting with the beans, hot-air roasting will be performed.

are transported in several buckets) 41 and placed in the storage tank 13 for raw Nehi beans of the hot air roasting machine A.

When performing far-infrared roasting using the bean roasting method of this example in the bean roasting machine of this example, use the hot air roasting machine A)
15, the combustion device 144 of the combustion chamber 2 is activated to generate hot air in the combustion chamber 2,
Hot air from the combustion chamber 2 is supplied to the roasting chamber 1.

In addition, the electric motor 7 is driven to rotate the advance device 5, and the opening/closing valve 1 is rotated.
4 is opened once, and a certain amount of the Nehi raw beans stored in the Nehi raw bean storage tank 13 and the far-infrared ray emitting ball B are transferred to the brewer 5 through the duct 15 and the raw bean input hole 11 which also serves as an exhaust hole. throw into.

Then, the hot air that has flowed into the roasting chamber 1 from the combustion chamber 2 flows into the brewer 5, which is rotating once, through the wire mesh lO opened at the rear end.
The Nehi raw beans and far-infrared radiation ball B transferred in the stand-up device 5 are heated, and are passed through the front end opening of the stand-up device 5, the green bean input hole 11 which also serves as an exhaust hole, the duct 15, and the blower (not shown) to a deodorizing device (not shown). leading to.

Tachimae! The far-infrared rays emitting ball B transferred in the I5 is heated by the hot air flowing through the stand-up device 5 and emits far-infrared rays, and the far-infrared rays heat the Nehi raw beans transferred in the stand-up device 5.

In other words, Nihi raw beans transferred within Tachimaeki 5 are Tachimae 3!5
The food is heated and roasted by the hot air flowing through it and the far-infrared rays emitted by the far-infrared rays B moving around in the brewer 5, and far-infrared roasting is performed.

When the nihi beans in the stand-up device 5 are roasted, the fried bean take-out hole 12 of the roasting chamber 1 is opened, and the nihi-fried beans in the stand-up device 5 and the far-infrared emitting pole B are transferred to the middle bottom plate 17 of the cooling tank 16. fall on top.

Then, the on-off valve of the air supply path 18 of the cooling tank 16 opens, and the rising air flow passing through the air passage hole of the middle bottom plate 17 of the cooling tank 16 causes the fried beans on the middle bottom plate 17 and the far-infrared radiation pole B to The cooling tank 16 is also stirred gt1.
9 rotates, and the knee and fried beans being cooled on the middle bottom plate 17 and the far-infrared radiation emitting pole B are stirred.

When the Nehi fried beans on the middle bottom plate 17 of the cooling tank 16 are cooled, a portion 20 of the peripheral part of the middle bottom plate 17 is bent to become a slope, and the cooling outlet holes 21 of the cooling tank 16 are opened. Nehi fried beans and far-infrared radiation pole B on the middle bottom plate 17 flow out from the cooling bean outlet hole 21 through the slope 20 of the middle bottom plate 17.

The roasted kohi beans and the far-infrared radiation pole B flowing out from the cooling bean outlet 21 of the cooling tank 16 flow into the inlet tube 32 of the separator c, and fall on the upper inclined plate 33 in the container body 31 of the separator C. do.

Then, the on-off valve of the air supply path 37 of the 5-separation bag 2IC is opened, and the rising airflow passing through the air passage hole of the upper inclined plate 33 causes the fried beans falling on the upper inclined plate 33 to rise (not shown). The far-infrared radiation pole B, which is transported to the storage tank for nehi fried beans and falls on the upper inclined plate 33, flows into the outlet tube 36 through the opening 34 and the lower inclined plate 35.

The far-infrared radiation pole B that has flowed into the outlet tube 36 of the separation device ff1C falls from the outlet tube 36, enters the packet 41 of the conveyance device, and is conveyed to the storage tank 13 of Nehi green beans of the hot air roasting machine A. will be put into the

The beans roasting method of this example can be carried out by adding far-infrared radiation pole B, separation device C, and conveyance device to the existing hot air roasting machine @A. It is easy to perform far-infrared roasting using A.

When performing hot air roasting in the bean roasting machine of this example, far-infrared radiation pole B, separation device C, and conveyance device 11 are used.
Only hot air roasting aA is used without using D.

Then, only the raw Nihi beans are put into the stand-up device 5 of the hot-air roasting aA, and the far-infrared radiation emitting pole B is not put in. The raw Nehi beans in the stand-up device 5 are distributed through the stand-up device 5. Hot air roasting is performed by heating and roasting only with hot air.

The bean roasting machine of this example can be easily used as a hot air roasting machine or a far infrared roasting machine.

Modified Example> In the bean roasting method and roasting machine of the embodiment, the separation of the Nehi fried beans and the far-infrared radiation pole B is performed after the Nehi fried beans are cooled, but it is not performed before the Nehi fried beans are cooled. You can also do this while the nehi fried beans are cooling.
