Abstract

PURPOSE:To miniaturize both a bean grinder and the whole apparatus and reduce cost of the bean grinder without impairing flavor by cooling coffee beans in a roasting chamber with a blower just after completing roasting, dropping and guiding the roasted coffee beans from a roasting vessel through a taking out passage into the bean grinder. CONSTITUTION:A heater 32, a rotor 14 and a driving device 36 are operated to roast coffee beans and a blower 37 is then operated to blow cool outside air on the coffee beans to rapidly air-cool the coffee beans. Viscosity of fats sticking to the surface is eliminated and surface seed coats or fine powder is simultaneously peeled and separated with winnowing action. Thereby, the aforementioned operation is sufficiently performed without impairing flavor of the roasted coffee beans to facilitate discharge of the coffee beans from a roasting vessel 31 after the roasting. Furthermore, a great force is not required even if the coffee beans are ground just after the roasting. After roasting the coffee beans in a roaster 3, a shutter device 82 is operated to open a taking outlet 81. The coffee beans in the roasting vessel 31 then drop in a taking out passage 83 by own weight thereof to enter a bean grinding chamber 42 without requiring a hopper.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Fields The present invention allows for easy roasting of green coffee beans (hereinafter referred to as green beans) even immediately after home-roasting them at home, coffee shops, coffee bean stores, etc. The present invention relates to a coffee bean roasting and grinding device that can grind coffee beans, can be made smaller and more compact, and has improved hygiene.

(b) Prior Art In general, coffee beans are the seeds inside the fruit of the coffee tree. Therefore, after harvesting coffee berries, coffee beans are obtained by removing the pulp and endocarp (parchment) from the berries.

Coffee beans contain caffeine, which is poorly soluble in cold water but soluble in hot water, tannins in the form of glycosides, sugars such as sucrose and loaded sugar, and fat.

Therefore, the coffee liquid obtained by processing coffee beans with boiling water has strong physiological effects, and by stimulating the central nervous system or muscles, it can tense the mind and body, relieve fatigue, and relieve sleepiness. This will improve your work efficiency. Also,
It has a cardiotonic diuretic effect and is said to have medicinal effects on headaches, especially migraines.

Coffee used to be a decoction-like drink, made by crushing green beans and boiling them.However, today, coffee beans are roasted, then crushed and boiled, or by permeating hot water. Drinking coffee liquid that has been infused with ingredients. When drinking coffee liquid, in addition to tastes such as acidity, concentration, bitterness, and smoothness obtained from these components, the aroma produced by roasting the caffeine and oil is enjoyed.

By the way, it is better to brew coffee immediately rather than brewing it for some time, and if too much time passes after it is roasted, it absorbs moisture and deteriorates in quality. In this case, it is known that the powder that has been crushed into fine powder is more likely to deteriorate in quality and its quality deteriorates further in a short period of time.

Also, if the ground coffee beans are too finely ground,
It is known that when processed with boiling water, excessive components are leached out, resulting in a so-called boiled-down taste and loss of flavor.

For this reason, traditionally, when roasting at home,
Using a wire mesh bean roaster, boil the beans over strong heat for 10 to 15 minutes.
The seed coat is constantly turned over to sift the burst seed coat through the wire mesh, and to prevent any powder finer than the wire mesh from remaining. Then, pour these freshly roasted beans into a coffee mill (
Grinding coffee with a bean grinder and brewing freshly ground coffee is considered the ultimate luxury among connoisseurs.

In response to such preferences, for example,
As shown in Publication No. 9, coffee beans are roasted in a roaster,
A fresh-pull coffee vending machine has already been proposed in which roasted beans are crushed in a coffee mill, treated with hot water in a coffee extractor, and then poured into a cup for vending.

(c) Problems to be Solved by the Invention However, the coffee roasting device used in this fresh-pull type coffee vending machine does not have a device to cool down the roasted coffee beans. If you grind hot coffee beans immediately, the coffee beans will become sticky and you will not be able to grind them evenly.
Grinding coffee beans immediately after roasting requires a large amount of force, requiring the use of a powerful and large motor in the grinding device. In addition, when coffee beans are roasted, fat content oozes out from the surface of the coffee beans, and this fat content causes dust such as burst seed coats and fine powder to stick to the surface of the coffee beans, making it difficult to remove them and leaving them as they are. Remains in coffee beans.

This dust is easily crushed into very fine pieces by the bean grinding device, and furthermore, when it is subsequently treated with boiling water, components are leached out excessively, resulting in a so-called boiled-down taste and impairing the flavor.

Furthermore, the fresh pull type coffee vending machine described in the above publication is configured to dump coffee beans into the coffee mill by inverting the roaster, so it takes a large amount of space to invert the roaster. It requires space, which is particularly disadvantageous to miniaturization and compactness. In addition, in order to ensure that some of the coffee beans that are thrown away from the roaster due to centrifugal force when the roaster is turned over are dropped into the coffee mill, the fresh pull type coffee vending machine described in the above publication does not use the coffee grinder. There is also an upwardly expanding input hopper on the side, which makes the coffee grinder even larger.

In addition, when coffee beans are dropped from the roaster into the coffee mill, the coffee beans, seed coats, and fine powder that burst from the coffee beans are scattered around and may remain inside the fresh-pull coffee vending machine and rot. , these residues may grow mold, which is disadvantageous in terms of degrading the layer flavor and improving hygiene, and in order to prevent these problems,
It is necessary to frequently clean the inside of the coffee vending machine, which makes maintenance troublesome.

The present invention has been made in view of the above circumstances, and allows beans to be ground immediately after roasting at home or in a coffee shop, while being downsized and compact, as well as being hygienic. It is an object of the present invention to provide a coffee bean roasting and grinding device that can increase coffee bean roasting and grinding.

(d) Means for Solving the Problems In order to achieve the above object, the coffee bean roasting and grinding device according to the present invention includes a coffee bean roasting device, and is arranged below the roasting device, A coffee bean roasting apparatus described in L is provided with a bean grinding device for grinding the coffee beans roasted by the roasting device, and a drop transfer device for transferring the coffee beans from the roasting device to the Juki bean grinding device by falling under their own weight. includes a roasting container that stores coffee beans, a heater that heats the coffee beans in the roasting container, a rotor that is rotatably provided in the roasting container, and a rotor drive device that drives the rotor. and a blower device for sending air into the roasting container, the L distribution air device includes an air passage having an inlet and an outlet, and a fan device, the inlet of the L distribution air passage is open to the atmosphere, The exit is 1-,
While opening into the roasting container, - the above-mentioned
1. The drop transfer device comprises a motor and a fan body that is driven by the motor and generates air blowing from the entrance to the exit of the air passage. an outlet; a shutter device for opening and closing the outlet;
The apparatus is characterized in that it includes a take-out path that guides the roasted coffee beans from the take-out port to fall into the bean grinding device.

The present invention will be explained in more detail below.

The coffee bean roasting and bean grinding apparatus of the present invention includes a coffee bean roasting apparatus, a bean grinding apparatus disposed below the roasting apparatus and grinding coffee beans roasted by the roasting apparatus, and a coffee bean roasting apparatus according to F. A drop transfer device is provided for transferring coffee beans from the roasting device to the grinding device by falling under their own weight.

So, the coffee bean roasting device described in 1-1 includes a roasting container that stores coffee beans, a heater that heats the coffee beans in the roasting container, and a rotor that is rotatably provided in the roasting container. and a rotor drive device that drives the rotor; 1-;
A blower device for blowing air into the roasting container is provided.

The roasting container that accommodates coffee beans may be configured so that coffee beans can be taken in and taken out and water vapor generated from coffee beans can be discharged during roasting. Alternatively, it may be constructed of a simple vertical or horizontal cylindrical container having an input/output port and a lid for opening/closing the opening.

1-The heater that heats the coffee beans in the roasting container is:
It may be placed inside the roasting container or outside the roasting container. However, unless the heater is used for stirring the beans, the heater is preferably placed outside the roasting container in order to facilitate stirring of the beans within the roasting container.

Further, the energy source of the heater is not particularly limited, and for example, electric power, thermal power, etc., which are relatively easy to handle, can be used. Examples of heaters that use electric power as an energy source include resistance heaters, high frequency heaters, and the like. In addition, when thermal power is used as an energy source, examples include various burners and furnaces that use liquid fuel such as alcohol, solid fuel such as charcoal, and gas fuel such as city gas and liquefied petroleum gas. I can do it. Among these, it is especially recommended to use electric heaters whose energy source is electricity, which is easy to control, and among electric heaters, it is recommended to use resistance heaters, which are easy to configure and are very cheap. be done. Furthermore, using these heaters as a heat source, heat is transmitted through a heat medium such as steam, hot water, or oil.
Alternatively, the far-infrared radiator may be heated by the heat source or heat medium, and the coffee beans may be roasted by the far-infrared rays emitted from the far-infrared radiator.

When roasting coffee beans with far infrared rays, for example, applying a far infrared emitting substance to the inner surface of the roasting container,
- The far-infrared radiator may be provided on the inner surface of the roasting container by forming the roasting container itself with a far-infrared radiator. In this case, the temperature of the heat source can be kept at a relatively low temperature or a low calorific value, which is extremely advantageous in terms of energy saving.

2 The blower device used in the present invention may be configured to send cool air into the roasting container, for example, it may include a blower path and a fan device having an inlet and an outlet,
[Opening to the atmosphere] 7. While opening the outlet into the roasting container, the device is connected to a fan body, such as a motor, which generates wind blowing from the inlet to the outlet of the air duct. Just configure it.

In the coffee bean roasting and grinding apparatus of the present invention, the coffee beans in the roasting container are roasted as evenly as possible by the heater, and are cooled as evenly as possible by the blower. Preferably, the coffee beans are stirred. Therefore, in the present invention, it is conceivable to rotate or swing the roasting container and to provide a stirring rotor in the roasting container.

However, the idea of rotating or rocking the roasting container has the disadvantage that the drive device for driving the roasting container must be relatively powerful and large.

Therefore, in the present invention, in order to roast the coffee beans in the roasting container as evenly as possible, a rotor is provided in the roasting container so as to be rotatable, and a drive device for driving this rotor is also provided. Recommended.

Note that this drive device may be a manual type or an automatic type using a motor or the like.

Furthermore, the direction of the rotational axis of the rotor is not particularly limited;
It may be oriented horizontally or diagonally. Furthermore, this drive device may be configured to rotate the rotor in one direction, or may be configured to swing the rotor back and forth in both forward and reverse rotation directions, but the configuration of the drive device and its control device In order to simplify the process, it is recommended that the rotor drive is configured to pivot the rotor in one direction.

In addition, in the present invention, as will be described later, by supplying wind into the roasting container using a blower device immediately after roasting is completed, fats and oils adhering to the surface of roasted coffee beans are cooled. The surface of the coffee bean loses its stickiness, and the peeled seed coat and finely ground powder are separated and roasted in the roasting container. Therefore, in the present invention, in order to prevent this seed coat and finely ground dust from scattering to the surrounding area and to facilitate its disposal, the seed coat that has been brocaded by the wind is roasted in a roasting container. It is preferable to provide a dust collection device for collecting dust outdoors.

The configuration of this dust collection device is not particularly limited, but it is preferable to configure it so that no special power is required to collect seed coats, finely pulverized dust, etc., in order to save energy. Therefore, for example, the roasting container may be configured with a bean loading/unloading port or a loading/unloading port and a lid covering the opening, and the dust collection device may be configured with an opening at the top of the roasting container. The dust collection pipe has a starting end that opens outside the roasting container and a terminal end that opens outside the roasting container, and a dust collection box connected to the end of the dust collection pipe. It is recommended that it be configured to collect dust such as ground powder.

In the coffee bean roasting and bean grinding apparatus according to the present invention, 15 is arranged such that the bean grinding apparatus is placed at the same height as the roasting container or at a higher position than the roasting container. This is not preferred because it requires a means to transport the roasted coffee beans and the configuration becomes complicated. Therefore, in the present invention, the bean grinding device is arranged at a lower position than the roasting container so that the coffee beans can fall under their own weight from the roasting container to the bean grinding device.

The bean grinding device may be located directly below the roasting container or may be laterally displaced from the roasting container as long as it is located lower than the roasting container.

In the coffee bean roasting and bean grinding apparatus according to the present invention, a takeout for taking out roasted coffee beans is provided at the bottom of the roasting container so that the coffee beans can be discharged from the roasting container without leaving any coffee beans due to their own weight. Provide an exit. In addition, in order to prevent coffee beans from falling from the outlet during roasting, a shutter device is provided to open and close the outlet, and further,
In order to ensure that the coffee beans discharged from the roasting container fall into the bean grinding device, a take-out path is provided for guiding the roasted coffee beans to fall from the take-out port to the bean grinding device.

6. Furthermore, in order to forcibly discharge the coffee beans in the roasting container from the roasting container through the outlet, it is preferable that the roasting container is configured with a vertically cylindrical container and that a scraper is provided in the roasting container.

Specifically, the roasting container is composed of a vertically cylindrical container, and a scraper that rotates along the inner bottom surface of the roasting container is connected to a rotor that is rotatable around the vertical center. The roasting container may be constructed of a cylindrical container with a horizontal axis, and a scraper that rotates around the roasting container may be connected to a rotor provided in the roasting container so as to be rotatable around the horizontal axis.

The configuration of the bean grinding device is not particularly limited, and for example, a commonly used bean grinding device of a manually rotary operation type or an automatic rotation operation type can be used.

That is, the housing includes a bean grinding chamber, an inlet passage extending upward from the bean grinding chamber and communicating with the lower end of the outlet passage, and an inlet passage opened downward or diagonally downward from the bean grinding chamber. A rotary mortar is rotatably accommodated in the bean grinding chamber, and the rotary mortar is connected to a drive device in series LM, and is fixed in the I-hound opposite to the rotary mortar. An example of this is a bean grinding device equipped with r1m.

The direction of the axis of rotation of the rotary mortar of this bean grinding device is not particularly limited, and may be oriented vertically, horizontally, or diagonally. Further, the distance between the rotary mortar and the fixed mortar may be fixed, but in order to be able to freely change the particle size of the ground bean powder, at least one of the rotary mortar and the fixed mortar may be fixed. Preferably, the housing is provided so as to be movable toward and backward from the housing, and an adjustment operating tool is provided outside the housing to adjust the distance between the rotary mortar and the fixed mortar.

In the coffee bean roasting and grinding device of the present invention, the rotor drive device of the roasting device and the mortar drive device of the bean grinding device may be provided independently from each other, but it is possible to reduce the number of parts as a whole. In order to simplify the configuration and reduce assembly costs, it is preferable to share a portion of the rotor drive device and the mortar drive device of the bean grinding device. In particular, when the rotor drive device and the mortar drive device of the bean grinding device are automated, a motor that drives the rotor of the coffee bean roasting device is provided, and this motor is used as the motor that drives the bean grinding device. By using the same function, the number of parts can be reduced and the configuration can be simplified.
It is possible to effectively reduce assembly costs.

In this case, the rotation axis of the rotor and the rotation axis of the drive shaft of the bean grinding device may be arranged coaxially or in parallel, or the rotation axis of the rotor and the rotation axis of the rotary mortar of the bean grinding device The cores may be arranged so that they intersect with each other in an elevational view.

(e) Function In the roasted coffee bean surface device of the present invention, in addition to the roasting container, heater, rotor, and rotor drive device provided in a conventional coffee roasting device, an air blower for blowing air into the roasting container is provided. A device is provided. This blower device includes a blower path and a fan device having an inlet and an outlet, - an inlet of the blower path is opened to the atmosphere, and an outlet thereof is opened into the roasting container; The device includes a motor and a fan body that is driven by the motor to generate air blowing from the entrance to the exit of the air passage. Therefore, after roasting the coffee beans 19- by operating the heater, rotor, and rotor drive device, by operating the blower, cool outside air is blown onto the roasted coffee beans, and the roasted coffee beans are rapidly air-cooled. The stickiness of the fat adhering to the surface of the coffee beans is eliminated, and at the same time, the seed coat and fine powder adhering to the surface are peeled off and separated from the coffee beans by wind-selection. This prevents the roasted coffee beans from losing their flavor, makes it easier to discharge them from the roaster after roasting, and eliminates the need for great force when grinding the coffee beans immediately after roasting. The motor of the grinding device can be made small and has relatively low output.

Furthermore, by separating dust such as seed coats and fine powder from coffee beans by wind selection, it is possible to prevent excessive leaching of components when the beans are treated with boiling water after grinding, and flavor loss can be prevented.

The coffee bean roasting and grinding device of the present invention further includes a coffee bean roasting device, and a leisure grinding device that is disposed below the roasting device and grinds the coffee beans roasted by the roasting device. , an outlet for taking out the roasted coffee beans at the bottom of the roasting container, a shutter device for opening and closing the outlet, and a dropping guide for the roasted coffee beans from the outlet to the bean grinding device. A take-out path is provided. Therefore, when the shutter device is activated to open the outlet after roasting coffee beans in the roasting device, the coffee beans in the roasting container will fall under their own weight in the outlet path and enter the bean grinding device. . Therefore, there is no need to invert the roasting container when transferring the coffee beans from the roasting container to the bean grinder, which eliminates the need for a large space for inverting the roaster, and prevents coffee beans from spilling when inverted. Since a hopper for preventing this is not necessary, it is possible to easily achieve miniaturization and compactness.

In addition, since the coffee beans are guided down the roasting container to the extraction path and fall into the bean grinding device, there is no risk of the coffee beans scattering around, and there is no need to clean the inside of the coffee roasting bean grinding device or its surroundings. This eliminates the risk of the scattered coffee beans rotting or mold growing on the scattered coffee beans, which improves flavor retention and hygiene.

(f) Examples Examples of the present invention will be described below in detail based on the drawings, but the present invention is not limited thereto.

FIG. 1 is a front view of a coffee bean roasting and grinding device according to an embodiment of the present invention.

This coffee bean roasting and grinding device includes a coffee roasting device 3,
A bean grinding device 4 is provided below the roasting device 3 and grinds the coffee beans roasted by the roasting device 3.

Immediately, a center block 2 is fixed on the left side of a base 1 placed on a table or the like, and a roasting container 31 of a roasting device 3 is fixed on the left side of this center block 2. Further, a housing 41 of the bean grinding device 4 is fixed to the left side of the center block 2, and a motor housing 5 is fixed to the right side. Further, on the front surface of the base 1, a switch 6 for turning on and off the operation of the coffee bean roasting and grinding device and a timer 7 for setting the roasting time of the roasting device 3 are provided.

FIG. 2 is a longitudinal sectional front view of the coffee bean roasting and grinding device.

The coffee bean roasting and bean grinding device 3 includes a roasting container 31 that accommodates coffee beans, a heater 32 that heats the coffee beans in the roasting container 31, and a rotatable space inside the roasting container 31. A rotor 34 is provided, a drive device 36 that drives the rotor, a blower device 37 that sends air into the roasting container, and a dust collection device 38.

The roasting container 31 of the roasting device 3 may be configured as a container having a bean loading and unloading opening or a loading/unloading opening and a lid covering the opening. A cylindrical pot 31a with a bottom that is open as a bean input port;
It is configured to include a lid 31b that opens and closes its top surface, and a net cover 310 that covers the surface of the pot 31a.

The double heater 32 may be placed inside the roasting container 31 or outside the roasting container 31.

However, here, since the heater 32 is not used for stirring the beans, the heater 32 is placed on the outside of the roasting container 31 in order to facilitate the stirring 3- in the roasting container 31.
That is, it is fixed to the bottom surface of the pot 31a.

Further, the energy source of the heater 32 is not particularly limited, and for example, electric power, which is relatively easy to handle, or the like can be used. As the heater 32 that uses electric power as an energy source,
Examples include resistance heaters and high frequency heaters. When thermal power is used as the energy source, examples include various burners that use liquid fuel such as alcohol, solid fuel such as charcoal, city gas, liquefied petroleum gas, and other gas fuels.

Here, an electric heater whose energy source is electricity, which is particularly easy to control, is used, and in particular, a resistance heater, which is simple in construction and very inexpensive among electric heaters, is used. Furthermore, using these heaters 32 as a heat source, it is also possible to heat coffee beans via a heat medium such as steam, hot water, or oil.

Here, in order to save power consumption by keeping the temperature of the heat source relatively low or with a low calorific value, the pot 31a is made of a material with high thermal conductivity, such as aluminum or stainless steel, which is free from food hygiene problems. , whose inner surface is double-coated with a paint made of a far-infrared substance and a coating agent containing ingredients that do not pose a food hygiene problem, and is heated by the heat of the heater 32 and the far-infrared radiation heated thereby. The coffee beans are heated with far infrared rays emitted from the body.

Further, an appropriate heat insulating space 33 is provided between the pot 31a, the lid 31b, and the net cover 310, so that the heated pot 31
Care is taken to prevent heat from being transferred from the pot 31a to the lid 31b and the net cover 31C, and to prevent the human body from coming into direct contact with the heated pot 31a.

The net cover 310 can also be constructed of a cylindrical body made of a flat iron plate bent into a cylindrical shape. However, here, in order to prevent heat from accumulating inside the heat insulating space 33 and to make it easier for the aroma accompanying roasting to be dissipated to the surroundings, a wire mesh formed by grating an iron plate is bent into a cylindrical shape. It constitutes a net cover 31c.

Inside the pot 31a, a rotor 34 for stirring the coffee beans and a scraper 35 for stirring the coffee beans and simultaneously discharging the coffee beans reliably are provided. It is intended to be driven.

This drive device 36 includes a horizontal axis motor 3611 housed in the motor housing 5, a horizontal axis drive shaft 361 directly connected to this motor 36a), and a horizontal axis drive shaft 361 directly connected to this drive shaft 36 (L via a bevel gear device 36c). Interlockingly connected vertical drive shaft 36
It is composed of d. ”-Structure shaft drive shaft 36I) is
It is rotatably supported on the right side wall of the center block 2 via a motor 36a, and the vertical drive shaft 3Ωd is supported by a bearing device 36e.
The vertical drive shaft 36d is rotatably supported on the upper wall of the center block 2 through the vertical drive shaft 36d, and the upper end of the vertical drive shaft 36d projects into the internal space of the pot 31a.

The rotor 34 and the scraper 35 are fixed to the upper end of the vertical drive shaft 36d.

The rotor 34 and scraper 35 may be formed separately, but in order to reduce component costs and assembly costs, they are formed by integral die-casting, for example.
It is formed integrally by

FIG. 3 is a longitudinal cross-sectional view of the coffee bean roasting and grinding device described in 1-.

As shown in the figure, the blower device 37 includes a blower passage 37c having an inlet 37a and an outlet 37b, and a fan device 37d disposed within the blower passage 37c. Then, the inlet 37a of the air passage 37c is opened to the atmosphere inside the center block 2, and the outlet 37b is opened to the roasting container 31.
A part of the inside is open. In addition, the above 7 amp air blower 3
7d is a motor 3 different from the motor 36a of the drive device 36.
7e, and a fan main body 37r that is driven by the motor 37e to generate wind blowing from the inlet 37a to the outlet 37b of the air blowing passage 37c.

Furthermore, the dust collection device 38 installed in - is equipped with an air blower RF! inside the roasting container 31. It is sufficient if the structure is such that dust such as seed coats and fine powder that are blown up by the wind of 37 is collected outside the roasting chamber. It has a starting end 38a that opens at a part of the inside of the roasting container 31, and is connected in communication with the dust collection pipe 38d led out from inside the roasting container 31 to the upper side of the motor housing 5 and its terminal end 38c. Dust collection box 38d
It can be composed of

In this case, by providing a large number of ventilation holes 38e on at least one surface (in this case, the upper surface) of the dust collection box 38d, the air blown into the roasting container 31 by the blower 37 naturally flows into the dust collection pipe 38b. and dust collection box 38d
and is discharged to the outside from the ventilation hole 38e. Then, the dust collection pipe 38b is removed from the roasting container 31.
The airflow that flows through the roasting container 31 to the dust collection box 38d
Inside the dust collection box 3Bd, the barge seed coat and powder generated during stirring are blocked by the upper wall having ventilation holes 38e.
It is designed to be collected within the

Further, this dust collection box 38d is provided so as to be separable from the dust collection pipe 38b so that dust such as seed coats and fine powder collected inside can be dumped at any time.

8 However, the above-mentioned roasting container 31 is not included in this dust collection device 38.
It is possible to provide a ventilation device for forcing air to pass through the dust collection frame 38b and into the dust collection box 38d.

This coffee bean roasting and bean grinding device is provided with a drop transfer device 8 in order to transfer the coffee beans from the roasting container 31 of the roasting device 3 to the bean grinding device 4. As shown in FIG. 2, this drop transfer device 8 transfers roasted coffee beans to a roasting container 3.
A take-out port 81 opened at the bottom of the pot 31a to take out coffee beans from the pot 31a, a shutter device 82 for opening and closing this take-out port 81, and a drop of roasted coffee beans from the take-out port 81 into the bean grinding device 4. During roasting, the shutter device 82 is closed to prevent the coffee beans from being taken out from the pot 31a. After collecting dust such as seeds and powder into the dust collection box 38d, the shutter device 82 is opened to mix dust such as seed coats and powder from the roasting container 31 of the roasting device 3 without using a special power device. Unground coffee beans can be transferred to a bean grinding device 4 by falling under their own weight.

This has a simple configuration, requires the minimum space required to transfer coffee beans from the roasting container 31 to the grinding device 4, and does not scatter coffee beans, their seed coats, powder, etc. The coffee beans can be transferred from the roasting container 31 to the bean grinding device 4, and this is advantageous in terms of energy saving.

” - The shutter device 82 may be configured to open and close the outlet 81. Therefore, the shutter device 82 has a structure that allows the outlet 81 to be opened and closed, and a shutter body 82a that opens and closes the outlet 81 and a drive device 82 that drives the shutter body 82a.
b, and in this case, the driving S device 821) is)
- It is housed in the base 2 and is configured to open and close the shutter body 82a via the wire 82d by driving the drive device 82b.

The shutter main body 82a may be provided so as to slide along the inner bottom surface of the pot 31n, or may be provided so as to swing within the take-out path 83.

When sliding along the inner bottom surface of the pot 3111, the pot 31. A conceivable configuration is to provide it swingably along the inner bottom surface of a.

In addition, when provided to swing within the extraction path 83,
A configuration in which the swing axis is disposed near the center of the take-out passage 83 and a configuration in which the swing axis is disposed near the inner circumferential surface of the take-out passage 83 or outside the take-out passage 83 are conceivable.

However, when the shutter body 82a mentioned in 1- is swung within the take-out passage 83, the weight of the coffee beans acts as resistance when opening the shutter body 82a, so the shutter body 82a must be operated with strong force. It is disadvantageous.

In addition, when sliding along the inner bottom surface of the pot 31a, the pot 3
In the structure in which the shutter body 82a is slidably provided along the inner bottom surface of the pot 31a, coffee powder gets caught between the shutter body 82a and the inner bottom surface of the pot 31a and creates resistance, so the shutter body 82a must be operated with strong force. This is a disadvantage.

1 Therefore, here, the outlet 81 is opened near the inner peripheral surface of the inner bottom surface of the pot 31n, and the shutter body 82a is
It is provided so that it can be moved linearly forward and backward in the diametrical direction of the take-out passage 83 between an open position where the take-out port 81 is fully opened and located outside of the take-out passage 83 .

The drive device 82) may be configured to open and close the shutter main body 82, for example, it may be configured by a near-remake, and the drive device 82) may be configured to drive the shutter main body 82 to open or close. Shutter body 82a
It is configured to open and close.

With this configuration, the entire coffee bean roasting and grinding apparatus can be made smaller and more compact, and the overall appearance of the coffee bean roasting and grinding apparatus is improved.

By the way, 9 is a stock chamber for coffee beans that have fallen, and when the coffee beans that have rapidly fallen from the pot 31a are not taken out smoothly, the coffee beans become clogged in the take-out passage 83 and the rotor is damaged. This is to prevent it from getting caught in the 34.

Therefore, the stock chamber 9 and the take-out path 3 communicate with each other, and the fallen coffee beans are pooled in the stock chamber 9 and gradually fall as the coffee beans are ground.

In addition, theoretically, in a coffee bean roasting and grinding device,
It is also possible for the roasting * fff 3 and the bean grinding device 4 to be installed at approximately the same height, or conversely, for the bean grinding device 4 to be installed higher than the roasting device 3, but in these cases, In order to transfer the coffee beans from the roasting device 3 to the W-J & device 4, a transfer device using, for example, a screw or a belt is required, and power is required for the transfer, so the configuration becomes more complicated. , which is disadvantageous when trying to save energy and is not desirable.

As shown in FIG. 2, inside the housing 41 of the bean changing device 4, there is a bean grinding chamber 42 and
An inlet passage 43 that extends diagonally in ten directions to the right from the grinding chamber 42 and communicates with the lower end of the take-out passage 83, and an outlet passage 44 that opens downward (or diagonally downward) from the grinding chamber 42 are formed.

In addition, a rotary mortar 45 is rotatably accommodated in the bean grinding chamber 42, and a fixed mortar 45 is placed opposite the rotary r1 disc.
There are 6. This fixed mill 'II 46 is formed in a donut shape and is fixed to the right end of the bean grinding chamber 42. The rotary mill 45 is disposed on the left side of the bean grinding chamber 42, and is operatively connected to the motor 36a via the horizontal drive shaft 36b of the drive device 36.

1- Rotation ``On the right side of the first plate 45 is a screw l1II.
By extending this screw shaft 45a to the lower end of the inlet passage 43, the coffee υ that has fallen into the inlet passage 43 passes through the hollow hole 4.6u of the fixed mortar 46 and is transferred to the rotary mortar 45. and the fixed F1 board 46.

Then, the coffee beans pushed between the rotating mill E1fi45 and the fixed mill gI46 are pushed between the periphery of the rotary mill 45 and the fixed mill 46, and are ground. It will fall below 41.

In this bean grinding device 4, at least one of the rotary mortar 45 and the fixed mortar 4#46 (here,
A rotating mill 45) is provided so as to be movable toward the other side, and a knob 48n for adjusting the distance between the rotary mill 45 and the fixed mill 46 is provided on the outside of the housing 41.

Immediately, rotating inside the housing 41, the first plate 45 is a fixed mortar fi.
Rotate the presser frame 47 that prevents it from separating from the frame 46 r1
This presser frame is attached to an adjustment screw 48 which is provided to be rotatable in the axial direction of the board 45 and the fixed mortar 46 and which is screwed into the left end of the housing 41 so as to be able to move back and forth. 47 is supported. Further, in order to easily adjust the fineness of coffee powder, a moderation device 50 is provided between the left end of the housing 41 and the operating knob 48a of the adjustment screw 47.
has been established.

, when the second coffee roasting and grinding device is installed, the lid 311 of the roasting container 31 is closed, the roasting time is set by the timer 7, and the heater 32 is turned on by turning on the switch 6. The drive device 36 is started and roasting begins. During roasting, the heater 32 is activated to generate heat I7, and the far-infrared radiator provided on the inner surface of the pot 31a emits far-infrared rays. Therefore, while the green coffee beans in the roasting container 31 are heated by the heat of the heater 32 and far infrared rays, the rotor 34 and the scraper 35 stir the coffee beans and roast them until the seed coats burst and the coffee beans are burnt brown. It is roasted. The degree of burnt coffee beans is adjusted by the roasting time, and when the roasting time has elapsed from the start of roasting, the temperature of the heater 32 changes! IIJ1 operation is stopped and the blower device 37 is started. Then, the coffee beans are cooled by the air blown into the roasting container 31 by the air blower 37, and the stickiness caused by the fat seeping out on the surface of the coffee grounds is eliminated.

Therefore, even when vertical grinding is performed immediately after roasting, the operating force or driving force of the bean grinding device can be weakened, and the beans can be easily ground immediately after roasting.

Further, since the operating force or driving force of the bean grinding device can be weakened, the motor 36a of the drive device 36 can be made smaller with a smaller capacity.

6 In addition, since the surface of the coffee beans is not sticky due to the wind from the blower 37, dust such as seed coats and powder attached to the surface of the coffee beans during roasting is easily removed by the wind, and the dust collected by the dust collecting device 38 is removed. The dust is collected in the dust collection box 38d. Therefore, after grinding roasted beans, other than the dust generated during bean grinding, dust generated by grinding the seed coat during grinding, dust generated by stirring the coffee grounds during roasting, etc. are included. This greatly reduces the risk of components leaching out and swirling when coffee is poured, resulting in a loss of flavor.

When a suitable time has elapsed since the blower device 37 was started, the blower device 37 is stopped and the shutter device 82 is opened. As a result, the coffee beans in the roasting container 31 fall into the bean grinding device 4 via the take-out path 83, are ground into coffee powder with an adjusted particle size, and then fall downward from the grinding device 4.

Therefore, there is no need to invert the roasting vessel 31, and a large space for inverting the roasting container 31 and a holder for preventing Ω etc. from collapsing during inversion are omitted.
2, and the entire coffee bean roasting and grinding device can be made small and compact.

Since the coffee beans are guided down from the roasting container 31 to the Ω inspection device 4 via the take-out path 83, there is no fear that coffee grounds, seed coats, and fine coffee powder will be scattered around. This method reliably prevents fine powder from remaining in the coffee bean roasting and grinding equipment and preventing it from rotting and from mold growing on these residues. Not only can you be freed from the hassle, but you can also maintain flavor and improve hygiene.

In addition, dust such as seed coats is removed from the coffee powder falling downward from the bean grinding device 4 by the dust cycle 11!2 device 38 during the bean grinding process. Except for the fine powder, there is hardly any finely ground coffee powder mixed in, and when this coffee powder is added, excessive leaching of coffee components is prevented and the flavor is enhanced.1. In the embodiment described above, the roasting container 31 is formed into a cylindrical shape with a vertical axis, but the roasting container 31 is formed into a cylindrical shape with a horizontal axis, for example, as schematically shown in FIG. Good too. In this case, the rotor 34 and the scraper 35 are configured to rotate around the horizontal axis. Further, the rotor 34 and the scraper 35 are interlocked and connected to a rotary mortar 45 of the bean grinding device 4 via a belt transmission device 36c.

In addition, in FIG. 4 1'', parts corresponding to the parts shown in FIGS. 1 to 3 are given the same names and symbols as each part shown in FIGS. 1 to 3. It is.

Further, although 17 is not shown in the drawings, the roasting container 31 is formed in a cylindrical shape with a vertical axis, the rotor 34 and the scraper 35 are configured to rotate around the vertical axis, and the rotating F1 plate 4 of the bean grinding device 4
5 rotates around the vertical center, or the roasting container 31
is formed into a cylindrical shape with a horizontal axis, and the rotor 34 and scraper 3
The present invention can also be applied in a case where the bean grinding device 4 is configured such that the rotary mill 45 of the bean grinding device 4 rotates around the horizontal axis.

(g) Effects of the Invention As described in (g), according to the coffee bean roasting and grinding device of the present invention, immediately after the roasting is finished, the roasting chamber (7) is
The coffee beans are cooled. Therefore, since the coffee beans lose their stickiness, it is possible to reduce the operating force of the bean grinding device when grinding the beans after roasting. l] device can be used, and the bean grinding device can be made small and inexpensive.

In addition, according to the coffee bean roasting and grinding device of the present invention, the fat content exuding on the surface of the coffee beans is cooled by the blower immediately after roasting, and the fat content that has oozed out on the surface of the coffee beans is cooled and dried. The seed coat and fine powder generated during roasting are easily peeled off from the surface of the coffee beans, and the seed coat and fine powder are easily removed by the wind from the blower. It can be peeled off from the coffee beans and removed. As a result, the amount of fine powder contained in the coffee powder after grinding the beans can be significantly reduced, and it is possible to prevent the flavor from being impaired due to excessive extraction of coffee components when coffee is brewed.

Further, according to the coffee bean roasting and grinding device of the present invention, the coffee beans are guided down from the roasting container to the bean grinding device via the outlet path, so there is no need to turn the roasting container upside down.
A large space for inverting the roasting container and a hopper to prevent beans from spilling during inversion can be omitted, making the entire coffee roasting and bean grinding device smaller and more compact. I can do it.

Furthermore, according to the coffee bean roasting and grinding device of the present invention, the coffee beans are guided down from the roasting container to the bean grinding device via the outlet path, so that the coffee beans, seed coats, and fine coffee powder are scattered around. There is no need to worry about coffee grounds, seed coats, and fine coffee powder remaining in the coffee roasting and grinding equipment, resulting in spoilage.
1. It can reliably prevent mold from growing on these residues and eliminate the trouble of cleaning the inside of the coffee standing double roasting machine. In addition to being freed from the heat, it is possible to prevent deterioration of flavor due to mold growth, prevent IF, and improve hygiene.

The invention is characterized by comprising a detection device that detects completion, a first control device that turns off electricity to the heater in response to an output signal from the detection device, and a second control device that moves the opening/closing device after a predetermined time. A coffee bean mill is proposed. ” (3) Same, page 7, line 19, change “this” to “this first

Add text. ``On the other hand, in the second conventional example, coffee beans are roasted using hot air, but when coffee beans are roasted using hot air, fat, etc. on the surface of the coffee bean and fat from the inside of the coffee bean are transferred to the surface. Fat, etc. oozes out, and this fat, etc. hardens on the surface of the coffee beans to form a fur, which prevents the coffee beans from barging and impairs the transmission of heat to the inside of the coffee beans. There are problems with raw roasting of coffee beans, such as uneven roasting of the coffee beans, resulting in the coffee beans smelling raw and deteriorating the flavor.Also, this method uses hot air to roast the coffee beans, but the top of the roasting container It has a ventilation hole for exhaust, and the hot air flows out through the ventilation hole, resulting in extremely low thermal efficiency, which requires a large-capacity heater. This is done using a detection device, but using this detection device causes the following problems. Namely, this detection device uses a thermistor or thermocouple to measure the temperature of the beans and the air passing between the beans. The temperature is detected and the degree of roasting of the coffee beans is determined based on the relationship between the two temperatures, but the layer thickness of the coffee beans changes depending on the stirring state of the coffee beans, and this changes the temperature of V and the thickness of the beans. The temperature of the air passing through the coffee beans changes, causing malfunctions.Also, the temperature of the coffee beans and the temperature of the air passing between the coffee beans is extremely delicate, and this subtle temperature difference can be corrected by using a thermistor or thermoelectric. It is difficult to detect in pairs, and the roasted state of coffee beans varies each time they are roasted.Also, as mentioned above, this device can detect the roasted state according to the preferences of coffee bean lovers. This is a serious issue, especially considering that these coffee enthusiasts demand strict roasting conditions for their coffee beans.-1 (5) Same, p. 9, from bottom The first line is ``Moreover,'' [Moreover, during this roasting, the coffee beans burst - heat is transferred to the inside of the coffee beans, and the coffee beans are evenly roasted.
