[Detailed description of the invention] [A field of use in business]

The present invention relates to a far-infrared drying method for seaweed and an apparatus therefor, in which seaweed on a seaweed cage is dried using a far-infrared heater in a dry seaweed manufacturing apparatus.

[Prior art and its issues]

In the dried seaweed production equipment, in addition to drying with warm air,
Far-infrared rays are partially used to dry seaweed. Drying with a far-infrared heater utilizes the properties of far-infrared rays, and has the advantage of improving the quality of dried seaweed, giving it a good taste and texture, a good gloss, and a long shelf life. A schematic diagram of a drying device for seaweed using a conventional infrared heater is shown in Figure 's8. In the conventional device, the seaweed cage S containing the seaweed N is attached to the transport conveyor C at a constant interval and parallel to the transport conveyor C, and is transported. The far-infrared heater H is arranged parallel to the seaweed surface of the seaweed N at a required distance. but,
The drying device with this structure has the following i! There was a problem. That is, since the seaweed cages S are installed parallel to the transport conveyor C, the pitch between each seaweed cage S is longer than the length of the seaweed cage S, and the number of sheets of seaweed N transported per unit length of the transport conveyor C in the feeding direction is reduced. can't do that much. Therefore, increasing the drying capacity of the drying device inevitably increases the size of the device and requires a large floor space for installation.

[Object of the present invention]

An object of the present invention is to increase the number of sheets of seaweed per unit length of the conveyor in the feeding direction, thereby increasing the processing capacity without increasing the size of the drying device.

[Configuration of the present invention] The configuration of the present invention taken to solve the above problems and achieve the object is as follows. In the far-infrared drying method for seaweed according to the invention of N1, in which the seaweed is dried by irradiation with far-infrared rays from a far-infrared heater, the seaweed cage is tilted at a predetermined angle with respect to the transport direction, and the seaweed is directly above the seaweed. The pitch between the seaweed cages is set as narrow as possible without interfering with far-infrared radiation to the seaweed, and the seaweed cages are installed on a conveyor.
This is a far-infrared drying method for seaweed in which the seaweed directly above the seaweed is dried by far-infrared radiation from a required number of far-infrared heaters arranged above a conveyor and approximately parallel to the surface of the seaweed cage. In the far-infrared drying device of the second invention, in the far-infrared drying device for drying seaweed by irradiating far-infrared rays from a far-infrared heater, the far-infrared drying device is provided with a conveyor, and the far-infrared drying device is provided with a conveyor. The conveyor has a plurality of holders that hold the seaweed cages at a predetermined angle with respect to the conveyance direction, and the holders are designed to hold the seaweed at an angle that does not interfere with far-infrared radiation to the seaweed directly above the seaweed. This far-infrared drying device for seaweed has a narrow pitch, and a required number of far-infrared heaters are disposed above the conveyor and substantially parallel to the surface of the seaweed cage held by the holder.

The present invention will be explained in more detail based on embodiments shown in the drawings. FIG. 1 is a schematic explanatory diagram of an embodiment of the present invention, FIG. 2 is an explanatory diagram of the holder seen from the front, and FIG. 3 is a side view of the main part of the t%2 figure. Reference numeral A denotes a far-infrared drying device, which includes a lower frame F1. The lower frame F1 is equipped with a conveyor C. The conveyor C has a structure that is driven by a drive device M. The conveyor C consists of endless chains C1 and C1 arranged in parallel (the chain C on the back side in Fig. 1).
1 is equipped with (not visible in the figure). Both chains C1,
Holders 1 for holding seaweed cages S are provided at regular intervals in C1. In addition, at both ends of the conveyor C, a delivery mechanism section (not shown) is arranged to transfer the nori cage frame to the holder 1. That is, this far-infrared drying device is generally installed in a part of the drying process of a dried seaweed production device. The structure of the holder l will be explained. The holder 1 is made by bending a band-like metal piece as shown in the figure, and one end is provided with a base 11 of the required width.The holder M311 has a screw hole (not shown). is provided, and one end thereof is raised substantially vertically across the platform 11 to form a stop W512. In this embodiment, the other end of the base part]1 is bent at an inclination angle of 15 degrees to form an inclined part 13, and the end part is bent at a right angle to the inclined part 13. A receiving portion 14 is formed. The holder 1 is fixed by screws 16 to a flange piece 15 integrally formed with an arbitrary roller link plate C2 of the chain C1 and projecting outward. Then, a seaweed cage frame 3 to which a plurality of seaweed cages S are attached is placed on the holder 1 of the chains C1 and C1, with a hook therebetween. Reference numeral F2 denotes an upper frame in which a required number of planar far-infrared heaters H are arranged in parallel. Note that the far-infrared heater is not limited to a planar heater, and may have a structure in which a rod-shaped heater is provided with a reflector. Each far infrared heater H
is attached so as to be inclined parallel to the inclined portion 13 of the holder 1. Note that the seaweed cage S attached to the seaweed cage frame 3 is designed to be approximately parallel to the inclined portion 13 when the seaweed cage frame 3 is placed on the holder 1. Therefore, the seaweed N collected on the seaweed pen S is also approximately parallel to the far-infrared heater H during transportation. Here, the structure of the seaweed cage frame 3 will be explained. As shown in FIGS. 2 and 3, the seaweed cage frame 3 has a structure in which both ends of a lower frame 31 and a lower frame 32 are connected by a vertical frame 33. The lengths of the upper frame 31 and the lower frame 32 are the same as the chains C1 and C1 of the conveyor C.
It is generally said that five to six seaweed cages S are installed between the two vertical frames 33. (Operation) The operation of this embodiment will be explained with reference to FIGS. 1J1 to 3. The pitch between the holders 1 of the chains C1 and C1 of the conveyor C is set to be as narrow as possible without interfering with far-infrared radiation to the seaweed N on the seaweed pen S attached to the holder 1. That is, during transportation, far-infrared rays are emitted from the far-infrared heater H arranged parallel to the seaweed cage S, which is inclined at 15 degrees with respect to the transportation direction. Far-infrared rays have a directional characteristic in which they are emitted at right angles to the heater surface, and cannot pass through the seaweed cage S. Therefore, the pitch of the seaweed cages S is set so that the far infrared rays passing through the rear end of the front seaweed cage S hit the front end of the seaweed N on the rear seaweed cage S, as shown in Figure 1. , the pitch of the holder 1 that holds the seaweed cage S is also set in accordance with the pitch. In addition, the conveyance method is generally an intermittent conveyance method. For example, when the conveyance speed is 6 seconds/time, the operation is repeated by stopping for 4 seconds and moving for 2 seconds. When stopped, the far-infrared heater H and seaweed N are almost completely removed. The far infrared rays are set to be parallel to each other and irradiate the seaweed N at right angles. According to this structure, when the inclination angle of the seaweed cage S is 15 degrees, the pitch of the seaweed cage S is approximately 73% compared to the pitch of the conventional structure, and with the same processing capacity, it is less than the pitch of the conventional structure. In comparison, the floor space is approximately 3
This means that it can be made relatively smaller. Then, the seaweed pen S is transported in the direction of arrow X and dried,
