Abstract

PURPOSE:To reduce electric heat and to roast a ginko nut, wheat or coffee beans in a tasty state, by constituting a roaster wherein hot air produced from a charcoal furnace is partially returned through a circulating hollow pipe to an electrically heated blower for hot air. CONSTITUTION:Charcoal is placed on the fire lattice 19, and electricity is applied to the heater 21. When the blower 22 is rotated, air heated at about 150 deg.C is fed through the feed cylinder 20 to the charcoal furnace 18, heated by charcoal fire into hot air at about 250 deg.C, and sent to the surroundings of the rotary cylinders 3. In this state, when the lever 17 is operated, and the on-off valve 16 is opened, coffee beans are introduced into the rotary cyclinder 3, heated at about 200 deg.C in the rotary cylinder 3 and roasted. During the operation, a large amount of dust is produced, it is sucked by the suction blower 13 and separated and removed by a cyclone collector of the water cooling type. Hot air is partially passed through the circulating hollow pipe 23 and circulated for use.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for roasting ginkgo, barley, and other coffee beans.

The present invention comprises a horizontally rotating cylinder made of a perforated plate, a charcoal furnace provided at the bottom of the cylinder, and an electric hot air supply device for supplying air to the charcoal furnace. A part of the generated hot air passes through the cylinder and is discharged outside the machine,
The gist of the roasting device is such that the remaining hot air returns to the electrically heated hot air supply device through a circulating hollow pipe.

To explain with a diagram, (l) is a case with a metal exterior and a fireproof material on the inside, and a rotating cylinder (3) is attached to the upper part of the interior of the case (1) with a horizontal transverse axis (2). Install the shaft. The cylinder (3) is formed of a perforated plate, one axial end of which is formed into an open opening (4), and the other axial end formed with a blind plate (
5) is occluded. (6) is a radial support that supports the cylinder (3).A supply cylinder (
7) is provided. A hopper is attached to the upper end of the face part (7), and the lower end (8) is attached to the open mouth (4) of the cylinder (3).
It is open facing inward. (9) is a discharge gutter, and a lid Ql that can be opened and closed is attached. One end o2 of a suction cylinder αυ is connected to the side of the supply cylinder (7). This is a suction blower, which is not shown in the diagram, but is connected to a water-cooled cyclone collector. αφ is an on-off valve installed in the suction cylinder αυ, α9 is a lever that opens and closes the valve a4, Oe is an on-off valve installed above the one end aX5 of the supply cylinder (7), and aη is the lever. A charcoal furnace brocade is installed in the lower part of the cylinder (3) in the case fl1, and an electric heating device Qυ is connected to the cylinder (1) to which the air supply ffJ wire is connected to the lower part of the grate a9. The device is a blower,
Connect a hollow pipe (c) to the suction port, and connect the hollow pipe (c) to the suction port.
The other end (to) of C) is connected to the upper part of the case (11). (C) is an adjustment lid, and (C) is an air replenishment port.

Next, we will discuss the effect.

For example, when roasting coffee beans, close the lid αI of the discharge gutter (9), place high-quality charcoal pre-ignited using a kiln, etc. on the grate Q'l, and turn on the electric heating device Q11. When the blower is rotated, air heated to about 150°C is supplied through the supply tube □ to the charcoal furnace αa', and the charcoal fire converts this into heated hot air C at about 250°C.
It is supplied on the day of.

In this state, when the lever α71 is operated and opened, the coffee beans flow into the rotating cylinder (3), where they are heated to approximately 200°C and roasted. The time required for roasting is about 15 minutes. During this time, a large amount of dust is generated, which is sucked by the suction blower 03 and separated and removed by the water-cooled cyclone collector. A portion of the hot air is circulated through a hollow pipe (c) for circulation.

Among the above-mentioned objects, the present invention relates to a horizontally rotating cylinder (3) made of a perforated plate.
), a charcoal furnace Og provided at the bottom of the cylinder (3), and an electrically heated hot air supply device that supplies the charcoal furnace, especially air. The gist of the roasting device is such that the hot air passes through the cylinder (3) and is discharged outside the machine, and the remaining hot air returns to the electrically heated hot air supply device through the circulation hollow pipe (c). Not only can coffee beans be roasted to a flavorful state using the hot air from the charcoal furnace α mallet, but a portion of the hot air is also circulated through the hollow pipe, which reduces the amount of electric heating required. This has the effect of providing a roasting device with low fuel consumption.
