Description
【発明の詳細な説明】 a、 産業上の利用分野 本発明は生海苔の処理方法に関する。[Detailed description of the invention] a. Industrial application field The present invention relates to a method for processing raw seaweed.
b、 従来の技俯

苔の塊りを通過させる方法がとられている。b. Conventional techniques Traditionally, raw seaweed is processed by shredding,
Paper making and drying processes are performed, vacuum freezing, peeling, and drying processes are performed to produce vacuum freeze-dried products, and dehydration, peeling, and frozen storage processes are performed for preservation. During these treatments, the peeling process is carried out either manually or by passing the nori clumps through a rotating blade.

来のほぐし処理のように単に非塊状にするだけでなく、
海苔の葉体どうしの面付着をなくした状態にしておけば
より速やかな凍結及び解凍が期待できる。C9 Problems to be Solved by the Invention In all conventional loosening processes, the water adhering to the surface is not sufficiently removed, so even after the loosening process, the adhesion of leaf bodies to each other cannot be avoided. In order to obtain a product, it is necessary to further loosen the material after drying, which is a rather difficult task. If there is a treatment method that prevents the adhesion of leaves to each other before drying, it would be easy to obtain dried pieces. Also, when storing raw seaweed in a frozen state, it is not only necessary to make it into non-clumps as in the conventional loosening process.
If the sheets of seaweed are kept in a state where they are not attached to each other, faster freezing and thawing can be expected.

苔を得ることができる。d. Means for Solving the Problem The present invention consists of washing and dehydrating fresh seaweed mainly consisting of leaf pieces with a thickness of 30 μm or more with fresh water or a salt solution, and converting the seaweed into a water-containing layer that does not cause mutual adhesion of at least the leaf bodies. This method is characterized by performing discrete processing in a dry atmosphere to a certain extent. By carrying out this treatment, it is possible to obtain seaweed in which the leaves do not stick to each other when a subsequent drying treatment or freezing treatment is performed.

を無くすることが困難になる。In the present invention, leaf pieces with a thickness of 30 μm or more have a thickness of 90 μm or more.
It is preferable to use raw seaweed containing % or more, and the thickness is 30 μm.
If less than 90% of the leaf pieces have a size of m or more, it becomes difficult to eliminate the overlap between the leaf bodies.

この実験では各種離散条件が海苔の離散終了持金・水率
とその離散状態とにおよぼす影響を調べた。Experiment 1゜In this experiment, the effects of various discrete conditions on the discrete end-money/water ratio of seaweed and its discrete state were investigated.

より通風した。First, it contains 95% of leaf pieces with a thickness of 30 pm or more, and has a leaf length of 2.
~5 cm of seaweed produced in Aichi Prefecture was washed with fresh water, centrifugally dehydrated, and dried. 1) Placed in 1, turned the 0-rotation shaft 2, and stirred with a stirring blade for $1.
) In Step 3, disperse the seaweed and dry the dry air.
The air outlet 4 is distributed almost evenly from the bottom to the top of ll.
More ventilation.
一定時間後攪拌を止め、そのまま通気乾燥を続け、乾燥
後、海苔の離散状態を観察した。結果は表−1にみられ
る如く、乾燥空気の温湿度、風量。After a certain period of time, stirring was stopped and air drying was continued, and after drying, the discrete state of the seaweed was observed. As shown in Table 1, the results are the temperature, humidity, and air volume of the dry air.
海苔投入量により設定される乾燥速度や攪拌羽根先端速

十分であった。なお、離散状態の判定は、葉体どうじの
付着が10%未満を良好、10%以上を不良とした。It has been found that regardless of the drying speed set depending on the amount of seaweed input and the speed of the tip of the stirring blade, if the discrete treatment is performed until the water content reaches approximately 400%, a good discrete state of the seaweed can be obtained. However, when the stirring blade tip speed was less than 1 m/sec, the dispersion was insufficient even though the water content was less than 400%. In addition, for the determination of the discrete state, less than 10% of adhesion of leaflets was evaluated as good, and 10% or more was evaluated as poor.

minutes, temperature 50℃, humidity 15%RH, stirring blade tip speed 1
.. The experiment was carried out under conditions of 0 and 2.0 m/sec, and the discrete frequency was adjusted by adjusting the rotation speed of a rotating shaft equipped with stirring blades and by intermittent operation. After performing the m-defeat treatment for 5 minutes, it was transferred to ventilation drying, and the results shown in Table 2 were obtained. Discrete frequency of seaweed is 40
If stirring was not performed more than once per minute, lumps would be formed during stirring and a good discrete state could not be obtained.

転/分、5分間遠心脱水した。Experiment 3゜In this experiment, when using salt R solution as the cleaning solution,
The influence of its type and concentration on discrete processing was investigated. Raw seaweed was washed with various salt solutions of 0 to 4% concentration and dehydrated by centrifugation at 1000 rpm for 5 minutes.
第2図はこの時の洗浄脱水含水率を示したものであり、
表−3は、第2図に表示された値の詳細を示す、同表に
みられるように洗浄液の塩の種類により傾きは異るが、
高濃度になるほど低下している。Figure 2 shows the water content of washing and dehydration at this time.
Table 3 shows the details of the values displayed in Figure 2.As seen in the table, the slope varies depending on the type of salt in the cleaning solution, but
It decreases as the concentration increases.

ば良好な離散状態は得られない。Furthermore, the amount of input is 0.6 kg, 1.2 kg, and wind 1
40i/min, temperature. Discrete treatment was carried out under the following conditions: 15% NO, a stirring blade tip speed of 2 m/sec, and a discrete frequency of 170 times/min. Figure 3 shows the case where the cleaning solution is saline, but when the concentration is high Indeed, a good discrete state cannot be obtained unless a low moisture content formation discrete process is performed.
このときの離散処理に要した時間は洗浄液の食塩濃度が
高いほど短い傾向にあり、離散処理時の初期含水率即ち
洗浄脱水含水率に影響されるようである。The time required for the discrete treatment at this time tends to be shorter as the salt concentration of the cleaning liquid is higher, and it seems to be influenced by the initial water content during the discrete treatment, that is, the water content of cleaning and dehydration.
食塩濃度が4%程度になると、海苔の攪拌羽根への付着
、絡みが多く歩止まりが悪くなるため3%以下が好まし
い。When the salt concentration is about 4%, the seaweed tends to adhere to the stirring blades and become tangled, resulting in poor yield, so it is preferably 3% or less.
良好なる離散状態を得るための離散処理終了時含水率の
上限は第3図より食塩濃度をX%としたとき(400−

合と同様に離散処理終了時含水率上限は(400−33
X )%で示される0表−4に換算係数の例を示した。From Figure 3, the upper limit of the water content at the end of the discrete process to obtain a good discrete state is when the salt concentration is X% (400-
33X)%. For other saline solutions, the slope is only different from that for saline water, and if you multiply the salt concentration by a conversion factor and make the salt equivalent concentration (400-33
Table 4 shows examples of conversion factors.

なる。Examples are shown below. In each of the Examples, fresh water was used as the wall cleaning solution that had been subjected to the same NJ treatment as in Experiment 3 in Example 1, and a 2% magnesium chloride solution was used in Example 2. At this time, the upper limit of the water content at the end of the discrete process to obtain a good discrete state is 400% 400-33 x 2 x O,8B = 342%.

Effects of the Invention Since the treatment of the present invention increases the surface area of seaweed due to its "glue effect," it is expected to improve the efficiency of subsequent treatments such as drying treatments such as vacuum freeze-drying and hot air drying, freezing treatments, and thawing treatments. It is possible to shorten these processing times and save energy.Furthermore, if it is performed as a pre-drying treatment, a new form of dried seaweed can be created, and it can respond to diversification of consumption.
