JPS6261562A - Apparatus for continuous softening and washing of raw laver - Google Patents

Abstract

PURPOSE:To enable the continuous softening and cleaning of raw laver, by forming a hollow part in the housing wall of a cleaning apparatus, providing a discharging hole connected to the hollow part and attaching an opening having an openable valve to the outside of the discharging hole. CONSTITUTION:The stirring blade 17 is rotated with a separate driving means. A mixed liquid of raw laver is supplied through the inlet port 25 into the housing H with a pump. The raw laver A introduced into the housing is ground, softened and cleaned because the rotary blade 17 is rotated along the direction of the arrow while pinching the raw laver between the edge of the hollow parts 15, 15 of the inner wall and the tip end of the vane 23. The softened and cleaned raw laver is discharged from the housing H through the discharging hole 27 together with a part of the stain water and defective laver generated in the softening and cleaning operation. The discharged laver is passed through a porous vessel to separate the staining materials and defective laver from the objective cleaned laver.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for continuously softening and cleaning raw seaweed.

[Prior art]

Conventionally, in order to soften and wash raw seaweed, a mixture of raw seaweed and seawater (hereinafter referred to as "
This was done by adding a raw seaweed mixture (hereinafter referred to as "raw seaweed mixture"), and then stirring this mixture with a stirring blade to generate friction between the blade and the mixture and friction between the raw seaweed and the raw seaweed.

However, this method had the disadvantage that the softening and cleaning process required time and labor because the raw seaweed mixture was added in a fixed amount at a time for softening and cleaning.

In order to eliminate this inconvenience, the present inventor has invented a continuous softening and cleaning device for raw seaweed that can continuously soften and clean raw seaweed, thereby saving time and labor for this process, and has already applied for a patent. Yes (patent application 1986-47140)
No.) [Structure of the invention] The present invention is a further improvement of the applied invention,
The purpose of the present invention is to provide a continuous softening and cleaning device for raw seaweed that can separate part of the waste water and defective seaweed generated during softening and cleaning of raw seaweed, and that can reduce the subsequent separation work. , comprising a cylindrical housing having an inlet and an outlet, and an agitation blade body installed in the housing and having a required number of elastic vanes radially, forming a required number of recesses in the inner wall of the housing, and , a raw seaweed continuous softening and cleaning device in which the stirring blade rotates while bringing the vane into contact with the inner wall of the housing,
A raw seaweed, characterized in that a discharge hole communicating with the recess is formed in the wall of the housing, the discharge hole is opened to the outside of the casing, and an on-off valve is installed in the opening. This is a continuous softening cleaning device.

[Action of the invention]

Since the raw seaweed continuous softening and cleaning device according to the present invention is configured as described above, by supplying the raw seaweed mixture from the inlet and rotating the stirring blade with the on-off valve closed, Raw seaweed is rubbed between the edge of the recess (inner wall) and the tip of the vane. Then, the raw seaweed is polished, softened, washed, and discharged from the outlet along with seawater. On the other hand, some of the dirty water and defective seaweed generated during softening and washing of raw seaweed passes through the recess, flows into the discharge hole, and is discharged to the outside of the casing by opening the on-off valve.

[Explanation of Examples]

Hereinafter, the present invention will be described in detail based on the drawings.

In the figure, 11 is an external cylindrical body having a discharge groove 11a on its inner wall surface, and 13 is a porous internal cylindrical body. The housing H of the present invention is constructed by fitting a porous inner cylinder 13 onto the inner wall surface of an outer cylinder 11 without any gaps, and covering the opening with a lid 14. The holes 15.15. of this cylindrical body 13. ...corresponds to the recessed portion of the housing in this invention. Reference numeral 16 denotes a discharge hole of the present invention, which is constituted by the discharge groove 11a of the outer cylindrical body 11 and the outer wall surface of the inner cylindrical body 13. This discharge hole 16 communicates with the hole 15 of the inner cylindrical body 13, and the discharge holes 16.16 also communicate with each other. 1st is a connecting pipe and is fitted into the housing H. This connecting pipe communicates the discharge hole 16 with the outside of the housing H. 20 is an on-off valve, and a connecting pipe 18
It is located in the middle of.

Next, reference numeral 17 denotes a stirring blade body, and a key 21 is joined to the rotating shaft 19 within the housing H. This stirring blade body 17 includes a required number of elastic vanes 23, 23. ..., and this vane 23.23. ... is rotated in the direction of the arrow while contacting the inner wall surface of the cylindrical body 13. 25 is an inlet, and 27 is an outlet, which are formed in the housing H. The raw seaweed mixture is supplied into the housing H from the inlet 25, and the softened and washed raw seaweed mixture is pushed out from the outlet 27. Note that 29 and 29 are bearings that support the rotating shaft 19, 31 is a sealing member, and 33 is a pulley that receives rotational force from a separate drive engine (not shown).

In order to soften and wash raw seaweed in this apparatus, first, the stirring blade body 17 is rotated by a separate driving means. Then, the raw seaweed mixture is supplied into the housing H through the inlet 25 by a pump. Then, inside the housing H, the raw seaweed A is sandwiched between the edge of the recess 15.15 in the inner wall and the tip of the vane 23, and the rotary blade body 17 rotates in the direction of the arrow, so that the raw seaweed A is Nori A is polished, softened and washed (see Figure 3).

Then, the raw seaweed that has been softened and washed is discharged out of the housing H from the outlet 27 together with the dirty water generated during the softening and washing and a part of the defective seaweed. After being discharged, a porous container (not shown) separates dirt and defective seaweed. Note that such separation may be performed using a centrifuge.

Incidentally, some of the dirty water and defective seaweed generated during softening and washing of raw seaweed passes through the recess 15 and flows into the discharge hole l6, and is discharged to the outside of the housing H by opening the on-off valve 20.

(Effects of the Invention) Since the raw seaweed continuous softening and cleaning device according to the present invention is configured as described above, part of the waste water and defective seaweed generated during the softening and cleaning of raw seaweed passes through the recess. The seaweed flows into the discharge hole and can be discharged to the outside of the casing by opening the on-off valve.Therefore, the work of separating waste water and defective seaweed after softening and cleaning is reduced.

Further, since the recessed portion of the housing communicates with the discharge hole, defective seaweed does not accumulate in the recessed portion, and as a result, the softening and cleaning performance of raw seaweed does not deteriorate even if the operation is continued for a long time.

In addition, if the housing is composed of an outer cylindrical body having a discharge groove inside and a porous inner cylindrical body, and the inner cylindrical body is fitted onto the inner wall surface of the outer cylindrical body without any gap, the housing having a discharge hole can be formed. can be manufactured extremely easily.
