Description

[Detailed description of the invention] The present invention relates to an automatic spraying device for granules on seasoned seaweed, and in particular, it is capable of automatically and efficiently depositing salt, sesame, or similar granules on the surface of the seaweed in a fixed amount and uniformly. The aim is to provide a device that can do this.

Conventionally, seasoned nori is produced by applying a seasoning liquid (so-called sauce) containing a mixture of mirin, soy sauce, kelp stock, chili pepper powder, etc. to the surface of dried sheets of seaweed, and then drying the seaweed. As a result, the state of the seasoning is not readily apparent from the appearance of the product, and consumers are not necessarily attracted to its delicious taste. Furthermore, when actually eaten, the texture is lacking, and the taste on the surface disappears, as if it immediately melts in the mouth. Furthermore, there is also the problem that the surface tends to be sticky and absorbs moisture in a short period of time, degrading the quality.

Therefore, in order to solve the above problem and give the product its characteristics, it is conceivable to attach salt, for example, to the surface of the seasoned seaweed. It is technically difficult to spray uniformly in a fixed amount in a short period of time, so it is difficult to do so until a product with a unique flavor that harmonizes the salt and seasoning liquid is commercially available. It can be said that this has not yet been achieved.

The purpose of the present invention is to provide a small and compact device that meets such demands, and its specific configuration will be described in detail below based on the illustrated embodiment. That is, Fig. 1 schematically shows a part of the seasoned seaweed production process in the present invention, where 1 is a device for baking the plate nori as a raw material, 2 is a seasoning device, and 3 is a drying device following the seasoning process. The plate nori is conveyed automatically and sequentially at a constant speed in the direction of arrow A in the figure by a belt or other conveyor 4 that passes through these devices 1, 2, and 3. It is becoming more and more like this. During the conveyance process, a seasoning liquid is applied to the surface of the sheet nori by a sponge roll (not shown) in the seasoning device 2 to form seasoned seaweed M, and the liquid is then transferred to the drying device 3. It will be twisted and dried.

As the seasoning liquid, in addition to the conventionally common formulations mentioned above, vegetable or animal edible oils can be used, and a mixture of the edible oil and the seasoning liquid can be applied. This edible oil can also be said to be beneficial in terms of moisture-proofing effect, photo-selectivity, and adding fat content.

5 is a general term for a granule scattering device interposed between the seasoning process and the subsequent drying process, and is fixed to the frame 6 of the conveyor 4.
It is installed on a horizontal bar 7 that extends across the conveyor 4. This device 5 is capable of applying salt, sesame seeds, and other similar granules onto a coating film a of a seasoning liquid on the surface of seaweed M in a short period of time until the liquid is dried and solidified. It automatically attaches the 2nd to 4th
As shown in the figure, it is formed as a unit body consisting of the following members.

That is, 8 is a support base detachably attached to the bar 7 with bolts and nuts 9, etc., and a vibration feeder 11 is installed on this with a vibration isolating rubber 10 interposed therebetween. This feeder 11
has a built-in magnet and a suction plate (both not shown) in its main body 12.
A dropping chute 13 for granules s and a granule storage hopper 14 are installed on the top surface, and leaf springs 15 are installed on both front and rear surfaces.
and a counterweight 16.
Then, the vibration is generated between the magnet and the suction plate, and due to the vibration of the leaf spring 15 and the chute 13, the accumulated granules s are thrown diagonally from the hopper 14 to the chute 13 and moved forward little by little as if dancing. (It may also be backwards.) Then, from the drop opening 17 of the chute 13, it is scattered onto the surface of the seasoned seaweed M in a natural fall manner. In other words, the natural frequency determined by the spring constant of the leaf spring 15 and the mass of the weight 16 is tuned (resonated) with the excitation frequency (power frequency) to obtain the necessary vibration amplitude. That's why. Anti-vibration rubber 10
The weight 16 prevents the feeding vibration of the granules s in the chute 16 from spreading to the base 8 and the bar 7.

In that case, the magnitude of the vibration amplitude is the same as that of the leaf spring 15.
This can be adjusted by changing the number of plates set in the plate springs 15, but furthermore, variations in the natural frequency due to deterioration of the leaf springs 15 can be adjusted by rotating the volumes VR ₁ and VR ₂ . This is absorbed as a change in the vibration frequency (power frequency), so that the speed at which the granules s travel through the chute 13 can be appropriately controlled. This means that the granules s on the surface of the seaweed M
Needless to say, it is useful for adjusting the amount of adhesion. The control principle is shown in Fig. 5, and the oscillation circuit P equipped with an astable multivibrator is

6, and by opening and closing it in the left and right directions, the granules s corresponding to the falling port 17 can be removed.
The spreading width of the seaweed M can be adjusted to be wide or narrow in response to changes in the band width W of the seaweed M. Incidentally, the band width W is usually about 190 to 220 mm. 27
is an elastic plate made of rubber or the like that forms a pivot point for opening and closing each side plate 26, and connects the fixed main body 25 and the movable side plate 26 with screws 23. Reference numeral 29 denotes a wing piece attached to each side plate 26, in which a slide guide elongated hole 30 for adjustment is opened. 3
Reference numeral 1 designates a bolt erected from the bottom side of the fixing body 25, and by screwing a nut 32 onto this bolt, the above-mentioned adjusted state can be fixed. In the illustrated embodiment, the bar 7 is used in common, and the granule scattering devices 5 are installed on it in a multiple series manner to cope with the seaweed M being conveyed in parallel. However, the present invention is not limited to this. Of course, in the case of such a multi-unit type, the fact that the spraying device 5 of the present invention is formed into a pre-unit body as described above improves installation workability and compatibility. It is extremely effective in expressing one's sexuality.
