The rear end of the rotating shaft 10 projects outward from the rear wall 4c of the cover 4, and the gear 11a fixed to the projecting end 10a is connected to the gear 11b fixed to the drive shaft 3a of the drive motor 3. It is set so that it is located directly above and engages with the other hand.

The front wall portion 4a of the cover 4 is provided with a supply port 12 for unbaked nuts and a discharge port 13 for baked products located below the supply port 12, both of which are opened in a position facing and communicating with the inner space of the mesh tube 8. At the same time, the supply port 12
A hopper 14 is fixed to the outer surface of the outlet 13 and has an arc shape from the front to the bottom, and a chute 15 is fixed to the outer surface of the outlet 13. ing. and,
Inside the hopper 14, a damper 16 is installed on both side walls 14.
It is mounted rotatably in a vertical plane via a horizontal rod 16a installed between the horizontal rods 16a and 14a, and mounting rods 16b, 16b hanging down from this. Due to the stored force of the coil spring 17 that is engaged between the letter-shaped handle 16c and the front wall portion 4a of the cover 4, the supply port 12 is always kept open.
It is designed to close the In addition, the outlet 1
Also on the outer surface of the chute 1, a damper 18 is fixed to the front wall 4a at its upper end via a hinge 18a, and this damper 18 normally closes the outlet 13 by its own weight, and in this closed state, the chute 1
The tip roll 19a is pivotally attached to the side wall portion 15a of No. 5.
By tilting the attached lock lever 19 backward, it is locked so that it cannot be opened.
Note that the lock lever 19 is operated by rotating an L-shaped handle 19b that is integrally fixed thereto and located on the outside of the chute 15. On the other hand, on the rear wall portion 4c of the cover 4, a handle 20 having a substantially U-shape on the outer surface side is attached to the lower end of both side rod portions 20b, 20b with the horizontal rod portion 20a being at a higher level than the top of the cover 4. It is fixed with bolts, and a gear part cover plate 21 is fixed below it.

The bottom of the roasting chamber 2 is composed of a mirror plate 22 fixed to the base 1 and having a concave arc-shaped cross section in the left and right direction.
A plurality of infrared heaters 23 are arranged at predetermined intervals along the front-rear direction at a predetermined distance from the mirror surface of the mirror plate 22.

By rotating the handle 16c upward, unbaked nuts are introduced into the hopper 14 with the supply port 12 open, and the nuts are supplied from the supply port 12 into the mesh cylinder 8. Then, by driving the drive motor 3, the gear 1
The mesh cylinder 8 rotates together with the rotating shaft 10 at a predetermined speed through the meshing of the meshes 1a and 11b. Due to this rotation, the individual particles of the nuts inside the mesh tube are constantly disturbed as they naturally collapse under their own weight to the bottom of the mesh tube. In this state, the infrared heater 23 is energized and heated for the required time. The product is roasted and baked.

Here, the roasted product is completely uneven due to the fact that the individual particles of nuts are constantly moving inside the mesh tube 8 during roasting and the heat source is an infrared heater with good heat permeability. The baked state is extremely uniform without burning, and the movement of the particles is not forced by a stirring rod or stirring blade, but occurs naturally with the rotation of the mesh cylinder 8, so that it is baked with a crust. In the case of nuts, it is of high quality with almost no peeling of the skin.

After the above-mentioned roasting is completed, the handle 19b of the lock lever 19 is rotated forward to unlock the damper 18 of the outlet 13, and then the handle 20 is lifted and the cover 4 is moved along the imaginary line in FIG. By tilting forward as shown, gears 11a and 1
1b is detached, the damper 18 opens naturally, and the fired product passes from the inside of the mesh tube 8 which is inclined integrally with the cover 4 through the outlet 13 to the chute 1.
5 and is taken out. Furthermore, damper 1
8 may be unlocked after the cover 4 is tilted.

The roasting apparatus of this invention is particularly useful for products with skins such as peanuts and almond nuts, but it can also be suitably used for roasting nuts without skins. In addition, the detailed structure of the roasting apparatus can be modified in various ways other than the above-mentioned embodiments. The mirror surface improves thermal energy efficiency, and the cover 4
By providing the air vent hole 6 in the nut, there is an advantage that an excessive increase in internal pressure due to vaporization of moisture contained in the nuts can be avoided.

Effects of the invention The roasting device of this invention is equipped with a roasting chamber equipped with an infrared heater at the bottom, and rotates around an axis along the horizontal front-rear direction inside a cover that covers the upper and side periphery of the roasting chamber. This is because the individual particles of nuts, which are constantly moving naturally inside the mesh cylinder that is stably rotated by a drive motor, are roasted by heating with an infrared heater. It is possible to obtain a product in a uniformly baked state without uneven burning, and in the case of nuts with skin, it is possible to obtain a high-quality baked product without peeling of the skin during roasting. Needless to say.

In addition, the roasting device of the present invention has a unique structure in that a supply port and a take-out port located below the supply port are opened in the front wall of the cover, facing the inner space of the mesh cylinder. , one end of the rotating shaft protrudes outward from the rear wall of the cover, and the gear fixed to this protruding end is positioned directly above and meshes with the gear fixed to the drive shaft of the drive motor. The cover is pivoted on a base at the front and is configured to be able to tilt forward integrally with the mesh cylinder, making it possible to tilt the cover forward during roasting operations, especially when taking out baked products. This can be accomplished by an extremely simple operation.

That is, when the cover is rotated forward around the pivot point after firing in the mesh cylinder, the gear on the protruding end of the rotating shaft of the mesh cylinder is directed upward from the gear on the drive shaft of the drive motor. It moves away and the cover tilts forward with the mesh tube without any problem. By this forward tilting, the fired product in the mesh cylinder is automatically moved toward the outlet and taken out outside the outlet. In this way, the roasting operation, especially the removal of the roasted product, can be performed by an extremely simple operation of tilting the cover forward, and the workability can be improved.

Furthermore, the roasting device of the present invention achieves the intended purpose with an extremely simple structure, and can be manufactured cost-effectively and can be installed in stores without any problems. It is also easy to make the device as small as possible.
