  The fish drying method of the present invention will be described based on the above configuration. First, as shown in FIG. 1 to FIG. 6, the conveyor C that sequentially transfers the fish F from the first drying chamber L1 to the fifth drying chamber L5 is bent downward before the entrance side of the first drying chamber. The section C1 is introduced into the cleaning tank 11, and the hot water cleaning section 13 is constituted by a large number of steam blowing nozzles N directed into the cleaning tank 11. By this hot water washing section 13, deposits such as mirin liquid and fish fat adhering to the conveyor C are boiled and washed by spraying steam onto the water in the washing tank 11. Subsequently, in the fish loading unit 10, the fish F are lined up in a row in units of 15 to 19 on the conveyor C by a manual operation by an operator. Immediately after this, the air E from the blower BW is sprayed onto the fish F by the air blowing means EB brought close to the conveyor surface, and the moisture W on the surface is blown off. Subsequently, germs attached to the fish F are killed and the drying chamber is sterilized by the sterilization lamp S provided at the top of each drying chamber L1 to L5. Further, the far infrared heaters EH1 and EH2 disposed above the conveyor C are heated to 240 ° C., the far infrared rays are irradiated to the fish F, and the inside of the fish F is heated and dried to about 33 ° C. At the same time, as shown in FIG. 7, the air flow EO in the first drying chamber is circulated in the forward direction by the blowing means MF1 provided on one side in the first drying chamber L1, and the fish F on the conveyor C is circulated. dry. Moreover, as shown in FIG. 8, the air F EO provided in the other side of the second drying chamber L2 circulates the air flow EO in the second drying chamber in the reverse direction to dry the fish F on the conveyor C. . Thereby, it becomes possible to dry the fish F on the conveyor C uniformly.

  Hereinafter, in the third drying chamber L3, the fourth drying chamber L4, and the fifth drying chamber L5, the air flow EO is alternately circulated in the forward direction and the reverse direction to dry the fish F on the conveyor C evenly. The air flow EO gradually absorbs the moisture and humidity of the fish in each drying chamber, and the humidity and temperature become higher than the initially set humidity (about 30%) and temperature (about 33 ° C.). Therefore, the dry air flow EO is always discharged from the discharge port 3B provided on one side wall surface in the first drying chamber to the fifth drying chamber, and the moisture is removed and the temperature is not raised by the dry air supply means 30 provided outside. ″ Is again sent from the blowing port 3A or 5A into the first drying chamber L1 to the fifth drying chamber L5 and circulated. The drying time is shortened by humidity management and temperature management of the air flow EO.

  Further, the fish drying apparatus 100 finishes drying at the outlet side of the fifth drying chamber L5, and the fish F is removed. Deposits such as fish cakes, fats, mirin liquid, etc. stuck to the conveyor C are peeled off by the water or hot water shower 15 constituting the brush cleaning unit 19 and the pair of rotating brushes 17 and 17 with respect to the conveyor C located here. And washed. The conveyor C returned to the entrance side is washed with hot water by the washing tank 11 of the hot water washing section 13 and a large number of steam blowing nozzles N toward the inside so that the mirin liquid or fish fat stuck to the surface is washed with hot water. It is surely boiled and washed. This produces high quality dried fish without adversely affecting the next drying of the fish.

  Then, the effect | action of the fish drying apparatus 100 which implements the said drying method of fish is demonstrated. First, in the hot water cleaning section 13 arranged on the inlet side of the first drying chamber, the cleaning section C1 of the conveyor C is introduced into the cleaning tank 11, and from a large number of steam blowing nozzles N directed into the cleaning tank 11 Only the adhering matter adhering to the conveyor C is washed with hot water with the sprayed steam. Next, in the fish throwing unit 10, the fish F are arranged in three rows on the conveyor C by the manual operation by the worker. Then, in the air blowing means EB disposed on the inlet side of the dryer main body, the air E from the blower BW is jetted onto the fish F by the three air blows brought close to the conveyor surface, and the moisture W on the surface is blown off. . Subsequently, the far-infrared heaters EH1 and EH2 arranged above the dryer body irradiate the fish on the conveyor with far-infrared rays to heat and dry the inside of the fish. At the same time, the air blowing means provided on one side of the first drying chamber and the other side of the second drying chamber in the dryer main body causes an air flow in the opposite direction for each drying chamber to be uniform. Promotes drying. At the same time, the dry air supply means provided outside the dryer main body supplies the dry air into each drying chamber to control the humidity. Finally, the brush cleaning unit disposed on the outlet side of the dryer body rubs the conveyor from which the fish has been removed after drying with a water or hot water shower and a rotating brush to peel off the deposits. Thus, drying by air flow humidity control improves drying efficiency by shortening the drying time and produces high-quality dried fish with the inside and outside of the fish dried uniformly. Furthermore, since the conveyor is washed on the outlet side and the inlet side of the dryer body, high quality dried fish are produced without adversely affecting the drying of the next fish.

  An embodiment using a fish drying method and a fish drying apparatus according to the present invention will be described. The conveyor C is set to have a width of about 1600 m / m, and the conveyor C transport speed is about 1.3 meters per minute so that the drive motor M1 makes a half turn around 15 minutes. The number was about 140 per minute and about 70,000 per day. As a result, for example, the salt drying time of fish such as horse mackerel, saury, barracuda, sardine, mackerel, red fish, etc., which took 1 hour and a half to 2 hours with a conventional batch-type drying apparatus, is the present invention. The drying apparatus 100 was shortened to about 15 minutes. In addition, the drying time for mirin drying was shortened to about 30 minutes by the drying apparatus 100 of the present invention, although the conventional batch type drying apparatus required 4 hours. As a result, the drastic reduction of the drying time not only improves productivity, but also reduces labor costs due to a reduction in work personnel and work time. As a result, high-quality dried fish is produced by improving drying efficiency and uniform drying, and labor costs can be reduced.

  According to the present embodiment, the following effects can be obtained. According to the fish drying method and the fish drying apparatus 100 of the present invention, the fish F conveyed on the conveyor C is irradiated with far infrared rays by the far infrared heaters EH1 and EH2 provided above the drying chambers L1 and L2. The difficult interior can be dried by heating. Furthermore, the air flow EO in each drying chamber can be circulated in the forward and reverse directions by the air blowing means MF1 and MF2 provided on one side and the other side in each drying chamber, and the air flow is supplied to the outside of the dryer main body LO. Since the humidity is controlled by the means 30 and circulated and supplied to the room again, the drying time can be shortened, the drying efficiency can be improved and uniform drying can be performed, and high-quality fish dried fish and mirin dried can be produced. Furthermore, labor costs can be reduced by reducing the number of workers and working hours.

  Also, the conveyor C on the outlet side of the dryer body LO is washed with fish residue and the like by the brush cleaning unit 19, and the conveyor C that has circulated and returned to the inlet side is heated with the hot water cleaning unit 13 to adhere mirin liquid or the like. Since the fish fat and the like are removed and boiled, the next time the fish is dried, the high quality dried fish and mirin dried can always be produced without adversely affecting the adhesion of the phosphorus solution or fish fat only the previous time.

  In addition, this invention is not limited to said embodiment. For example, although the first embodiment of the present invention has been described with the configuration in which the five drying chambers L1 to L5 are arranged in tandem, the dryer main body LO including at least the first drying chamber L1 and the second drying chamber L2 is used. Any number of sets may be used, and a dryer body including six or more sets of drying chambers may be used. Moreover, although the example of the net conveyor was given and explained about the conveyor, it is not limited to this, and various conveyors applicable to the implementation of the present invention can be used. In these embodiments, the same operation and effect as the drying apparatus 100 of the first embodiment can be obtained.

  The fish drying method and fish drying apparatus of the present invention have been described by taking horse mackerel, saury, barracuda, sardine, mackerel, red fish, etc. as examples, but are not limited thereto, and various small fish and large fish fillets The present invention can also be applied.
