Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a roasting machine for roasting coffee beans.

(Prior art) Conventionally, coffee beans housed in a roasting container are heated with a heater while being stirred, and after a prescribed roasting operation, the coffee beans are transferred from an outlet provided in the roasting container to a cooling box of the roasting container. Various roasting machines have been proposed in which roasting is carried out by dropping and depositing the roasting material. In such a roaster, a chute is provided between the outlet and the cooling box in order to prevent the coffee beans discharged from the outlet from spreading and scattering outside the cooling box while falling. There is. This chute has a wide opening on the side of the outlet and is narrowly constricted on the side of the cooling box, that is, the lower end, and serves to reliably accommodate the falling coffee beans in the cooling box.

(Problem that the invention aims to solve) However, because the lower end of the above chute is narrowly constricted, the falling coffee beans tend to be biased or concentrated in one place in the cooling box and accumulate. However, even if the cooling box is large, there is a problem that if the amount of accumulated sediment exceeds the depth of the cooling box, it will eventually flow out of the cooling box. Therefore, in order to prevent such intensive accumulation of coffee beans, it is necessary to constantly monitor the amount of accumulated coffee beans, and when the amount exceeds a predetermined value, it is necessary to carry out cumbersome work such as spreading the coffee beans around by hand. There was a problem. In addition, concentrated accumulation of coffee beans in the cooling box hinders uniform cooling of the coffee beans and causes variations in the flavor of the coffee beans.

(Purpose of the invention) The present invention was devised in view of the above-mentioned conventional problems, and is designed to allow coffee beans falling from the outlet of a roasting container to fall and accumulate evenly over almost the entire area inside the cooling box. To provide a roasting machine which can reduce the size of a cooling box to the necessary minimum size, cool coffee beans uniformly, and prevent variations in the flavor of the coffee beans.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention has the purpose of storing the coffee beans 30 in the roasting container 11 at the end of roasting into the cooling box 43 installed at the bottom of the roasting container 11. In a roasting machine that discharges and drops coffee beans, a flow regulating member 41 having a plurality of flow paths for uniformly dispersing the falling coffee beans 30 is provided between the coffee beans 30 outlet 16 of the roasting container 11 and the cooling box 43. It is characterized by having been installed.

(Function) In the present invention, all the coffee beans scattering and falling from the outlet are introduced into the rectifying member whose upper end faces the vicinity of the outlet, and the plurality of flow paths of this rectifying member are branched, and each of the flow paths is divided into two. According to the direction of the path, coffee beans are distributed and deposited evenly over substantially the entire area inside the cooling box.

It is attached to the intake hole 37 of No. 4, and a wire mesh is stretched on the bottom so that air can flow to the intake hole 37.

Next, the operation will be explained.

First, the coffee beans 30 are introduced into the glass container 11 through the input duct 38 and the input port 15 by opening the input door 39. Subsequently, the motor 13 is driven and the heater 27 is heated. Further, the motor 35 is also rotated around this time. The coffee beans 30 in the glass container 11 are roasted by being stirred by the blade 28 while receiving heat from the heater 27 .

On the other hand, when the coffee beans 30 are finished roasting, the glass container 11 is tilted so that the outlet 16 side is lowered, and the lid 17 is opened. Therefore, the coffee beans 30 in the glass container 11 fall downward from the outlet 16. Note that at this time, the blade 28 continues to rotate, and this acts to send the coffee beans 30 out of the outlet 16 while stirring them.

The coffee beans 30 that are sent out in this way and fall from the outlet 16 are transported to the flow regulating plate 4 of the flow regulating member 41.
It is guided in the direction of the rectifier plate 41b through a plurality of flow passages separated by 1b, and falls and accumulates in the cooling box 43. For this reason, the coffee beans 30 are distributed in each direction by each rectifying plate 41b, and are deposited and distributed almost evenly in each part of the wide range of the cooling box 43, and are concentrated or biased in one part. Never. As a result, the height at which the coffee beans are piled up is made almost uniform, so that the height of the cooling box 34 can be reduced, so that the shape of the cooling box 34 can be made as small as possible.

Note that the shape and size of the upper opening end of the flow regulating member 41 are such that the coffee beans 30 falling from the outlet 16 are
The shape and size of the opening of the cooling box 43 should be such that all of the flow can be collected by the flow regulating member 41.
It needs to be able to catch all the coffee beans that pass through it.

(Effects of the invention) As explained above, the present invention provides a roasting machine that discharges and drops coffee beans in a roasting container into a cooling box installed at the bottom of the roasting container at the end of roasting.
A flow regulating member having a plurality of flow paths that evenly disperses the falling coffee beans is installed between the coffee bean outlet of the roasting container and the cooling box, so that the coffee beans discharged from the roasting container can be The coffee beans are no longer concentrated in one part of the cooling box, and are deposited at an approximately uniform height. Therefore, it is possible to prevent coffee beans from inadvertently flowing out of the cooling box. Furthermore, the shape of the cooling box can be made as small as possible, and the temperature distribution of the coffee beans in the cooling box is uniform, which provides the advantage of being able to obtain roasted coffee beans of constant quality through uniform cooling. have
