Description

The present invention relates to a roasting apparatus such as mushrooms and seafood, details about the roasting apparatus for food with steam and far infrared radiation heating generated ultrasound.

As this type of roasting apparatus, a plurality of feeders having an ultrasonic humidifier, a cooling blower, and an electromagnetic vibrator in a main body frame and having a sheet heater directly above are provided with steps in the conveying direction. The tea leaves supplied from the hopper are dried with a planar heater, or the feeder belt is vibrated in the front-rear direction with an electromagnetic vibrator, and the tea leaves are dropped and conveyed from the lower end of the inclined belt onto the belt located below, or There has been proposed an ultrasonic humidifier that is used by filling the frame with water vapor or by blowing air or nitrogen gas into the frame (for example, see Patent Document 1).
However, the roasting apparatus described in Patent Document 1 is configured to uniformly supply water vapor or gas from the cooling blower into one main body frame. Even if it is a portion, it is evenly humidified and is suitable for processing foods that require repeated drying and humidification, such as tea leaves, but only once drying and roasting, such as shiitake mushrooms and seaweed It does not apply to those that require roasting. In addition, the electromagnetic vibrator vibrates the feeder belt in the front-rear direction in order to drop the tea leaves in the conveying direction from the lower end of the inclined belt to the lower belt, and to drop the individual pieces of tea leaves. Since it is not intended for humidifying or roasting at a distance, there is a problem that tea leaves are stuck together and become a lump, and uniform humidification and roasting cannot be performed in a state where the tea leaves are scattered. It was.
In addition, a belt in which a transfer belt moves in a microwave irradiation device and a far infrared irradiation device has been proposed (see, for example, Patent Document 2).
The invention described in Patent Document 2 has an advantage that the processed food is not deformed because the microwave trap can be vibrated in the vertical direction to allow food with a height to enter and exit the apparatus. Since the food is simply conveyed on the belt conveyor in a stationary state, uniform drying or the like is difficult, and there is a problem that individual food materials may adhere to each other and become a lump.
Although the use is different from that of the present invention, a belt conveyor is formed in the center of the box in the height direction so that the belt conveyor can pass therethrough. Has proposed a heating / drying apparatus equipped with a heating device capable of directly heating an object on a belt conveyor (for example, Patent Document 3).
However, in the case of the invention described in Patent Document 3, a far-infrared heater is used when heating an object fed into a heating / drying apparatus on a conveyor belt, and a far-infrared heater is not used when humidifying. The water in the water storage tank is energized through a water temperature adjusting heater and heated to a predetermined temperature to increase the water vapor pressure. As described above, the drying in the combined heating and drying apparatus is performed by heating while suppressing drying in a high humidity atmosphere, so that the objects to be dried may adhere to each other in a lump shape. There is a problem that the food material is unsuitable for uses that require drying so that any portion of each food material has a uniform moisture content without adhering to each other.

To pass through.

Next, the operation will be described. The food material in the hopper 2 is supplied onto the vibration receiving plate 3 while the fall supply amount is adjusted by the control means. When the motor 8 is driven, the eccentric shaft 7 rotates. When the circumferential surface of the eccentric shaft 7 located at a long distance from the shaft portion of the eccentric shaft 7 collides with the bottom plate 4 of the vibration receiving plate 3, the vibration receiving plate 3 is pushed upward. When the circumferential surface at a position short in distance from the shaft portion of the eccentric shaft 7 is positioned below the bottom plate 4 of the vibration receiving plate 3, the vibration receiving plate 3 is lowered. Since the coil spring 10 is mounted between the back surface of the vibration receiving plate 3 and the horizontal rail of the support frame 1, the vibration receiving plate 3 moves up and down in response to the rotational movement of the eccentric shaft 7 and is supplied from the hopper 2. The food material moves while jumping in the transfer direction by the vibration of the vibration receiving plate 3. By this movement, the food material on the vibration receiving plate 3 is fed onto the belt conveyor 15. When the motor 18 is driven, the motor shaft rotates and the endless belt 19 rotates to rotate the driving belt wheel 16. The belt conveyor 15 rotates, and the food material fed from the vibration receiving plate 3 moves on the belt conveyor 15 and is fed onto the transfer plate 23. The motor switch 41 of the operation unit 44 is turned on, and the amount of steam discharged from the steam ejection pipes 40 and 40 is adjusted by the ultrasonic control box 42. When the motor 22 is driven, the eccentric shaft 30 starts to rotate via the continuously variable transmission 34, and the transfer plate 23 starts to vibrate in the vertical direction. The vibration width of the transfer plate 23 can be adjusted by adjusting the angle between the adjustment metal plate 38 and the transfer plate 23. More specifically, when the adjustment metal plate 38 is lowered, the vibration width of the transfer plate 23 decreases, and when the adjustment metal plate 38 rises, the vibration width of the transfer plate 23 increases. When the transfer plate 23 vibrates in the vertical direction, the food material on the transfer plate 23 jumps and moves in the transfer direction, and the food material jumps in the course of movement on the transfer plate 23 and is sprayed from the steam ejection pipe 40 while being finely steamed. It is transferred while bathing. Due to the vibration of the transfer plate 23, the food material is exposed to steam while jumping on the transfer plate 23, and thus can be uniformly and uniformly exposed to steam. Further, it is transferred and roasted while receiving far-infrared radiation from the planar heater 49 while jumping on the transfer plate 23. Due to the vibration of the transfer plate 23, the food material is uniformly dried and roasted without burning. The dried and roasted food material is fed onto the conveyor belt 54 while jumping. The food material passes through the ultraviolet irradiation processing device 52 in a stationary state on the conveyor belt, and is subjected to ultraviolet irradiation processing. This ultraviolet irradiation treatment increases vitamin B1 and vitamin D depending on the food material. After passing through the ultraviolet irradiation processing device 52, the food material is further fed into the far infrared irradiation processing device 53, and is subjected to the far infrared irradiation processing in a stationary state on the conveyor belt and dried.
The obtained product was not burnt, and it was a dry food rich in nutrients and rich in vitamins as compared with the conventional product.
