Description

  The present invention relates to a dried laver production system for producing dried laver.

  BACKGROUND ART Conventionally, a dried laver production system has been used to produce rectangular lamellar dried laver from harvested laver progenitor algae.

In this dried laver production system, dried laver is mainly produced as follows.
First, a seaweed raw material obtained by mixing seaweed progenitor algae and water is prepared to a predetermined concentration using a blending device.
Next, the laver material is discharged onto a laver cage using a papermaking apparatus to form a rectangular plate-shaped laver material.
Next, the dried laver is dried together with the laver cage using a drying device to produce dried laver.
Next, the dried laver is peeled from the laver cage using a peeling device.
Finally, the weight and the like of the dried seaweed are measured using a sorting device, and the dried seaweed having a weight and the like (quality) in a predetermined range is sorted.

  As described above, conventionally, dried laver having a predetermined range of weight has been manufactured by adjusting the concentration of the laver material using a blender (for example, see Patent Document 1).

Japanese Patent Publication No. 1-48749

  However, since dried laver is produced by drying the laver raw material with a drying device, the drying condition in the drying device varies from day to day under the influence of temperature, humidity, and the like. Fluctuation (variation) occurs in the weight.

  Therefore, in the above-mentioned conventional dried laver production system, even if the concentration of the laver raw material in the blending apparatus is adjusted based on past experience and the like, the weight of the dried laver produced according to the actual dry state varies, It has been difficult to stably produce dried seaweed of a desired weight and thus of a desired quality.

Therefore, in the present invention according to claim 1, the laver material whose concentration is adjusted by the blending device is formed by a papermaking device to form a laver material, and the formed laver material is continuously transferred to a drying device by a transport mechanism. In the dry laver production system for transporting and drying the laver dough in the transport path inside the drying apparatus in order to produce the dried laver, the control device should dry the transport path inside the drying apparatus from the start of drying of the drying apparatus. During the time until the laver is filled with the laver dough, the concentration of the laver raw material produced by the laminating machine was measured, and the weight of the dried laver from which the laver material was dried was measured and measured. The relationship (concentration / weight relationship) between the concentration of the dried seaweed and the corresponding weight of the dried seaweed is determined, and the concentration of the seaweed material corresponding to the set weight of the dried seaweed is determined using the concentration / weight relationship. Internal transport path of the drying apparatus to a concentration of the raw material is to control the compounding device after filled with seaweed material to be dried.

Further, in the present invention according to claim 2, in the present invention according to claim 1, the control device is configured to perform a process from the start of drying of the drying device until the transport path inside the drying device is filled with the laver material to be dried. The blending device was controlled so that the time became the concentration of the seaweed raw material set in advance .

  The present invention has the following effects.

  That is, in the present invention, dried laver is produced by laminating a raw material of laver having a concentration adjusted by a dispensing device and forming a laver material by a laminating machine, and drying the laver material thus formed by a drying device to produce a dried laver. In the system, while measuring the concentration of the nori raw material made by the papermaking equipment, the weight of the dried nori dried from the nori dough formed from the nori raw material is measured, and the measured concentration of the nori raw material and the corresponding The relationship between the weight of the dried seaweed (concentration / weight relationship) is determined, and the concentration of the seaweed raw material corresponding to the set weight of the dried seaweed is determined using the concentration / weight relationship so that the concentration of the seaweed raw material is obtained. Since the blending device is controlled, it is possible to adjust the concentration of the seaweed raw material corresponding to the actual dry state of the seaweed dough, and to stably produce dried seaweed having a desired weight (quality). That Kill.

  In particular, when the concentration / weight relationship is determined for the dried seaweed dried within a predetermined time from the drying start time of the drying device, or the predetermined time is filled with the seaweed dough in which the inside of the drying device is to be dried. In the case of the time required for the drying, the concentration-weight relationship can be obtained at the initial stage of the operation of the dried laver production system, and the dried laver having a desired weight (quality) can be stably produced for a long time thereafter. can do.
