Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for producing dried mozuku using raw mozuku (mozuku original alga body) as a material and a production apparatus for dried mozuku, and more particularly to a method for improving drying efficiency and reducing drying cost.
[0002]
[Prior art]
Conventionally, the main processed food of mozuku is food that is prepared by adding three glasses of vinegar to processed raw mozuku. Recently, the raw mozuku has been dried into a dried mozuku, which is then enclosed in a vacuum pack or the like and distributed. This dried mozuku is returned to water immediately before use to make a raw mozuku, and is used as food to be eaten by adding three glasses of vinegar.
[0003]
Also, the dried mozuku is used as it is or slightly returned to water, and is used for foodstuffs such as "mozuku tsukudani", "mozuku matsumae pickle", "mozuku kimchi", "tempura noodles", "miso soup noodles", "porridge". Furthermore, it is processed into powdery powder and used as food mixed with buckwheat flour or the like. Recently, the range of uses other than foods for the dried mozuku has been expanded and utilized actively. For example, dried mozuku containing a fucoidan component having anticancer activity and moisturizing power is processed into powdery fine powder to be used as a material for foods and cosmetics, thereby bringing out the utility of fucoidan.
[0004]
As for the method of drying the raw mozuku, most of the fucoidan and mineral components with anticancer activity are abundant in the slimming of the viscous substance attached to the surface of the raw mozuku, and the raw mozuku is washed. Then, since the fucoidan and the mineral components are washed away together, the drying has been performed with the slime adhered. For drying the raw mozuku, a method of air-drying with hot air using a drying apparatus for laver or a drying apparatus for tobacco or green tea, or a cold air drying apparatus for drying at 20 to 30 ° C. is used.
[0005]
As described above, if raw mozuku is air-permeable and dried with its surface adhered, the drying time becomes extremely long because the slimy layer becomes a film and cannot be passed through by hot air. For this reason, a large drying cost was required. In addition, if the mozuku product temperature rises due to a decrease in the drying speed and the mozuku is boiled, the mozuku becomes discolored and becomes soft, resulting in extremely loss of texture. Further, if the raw mozuku layer has uneven thickness, it remains as dry unevenness, and when immersed in water to return to the raw mozuku, the water permeability is poor and a long time is required, and the original texture is not obtained.
[0006]
However, as described above, the applicant of the present invention abundantly contains the fucoidan component and mineral component having anticancer activity in the slimming of the viscous substance attached to the surface of the raw mozuku. The following experiments were carried out with the doubt that the quality value as mozuku would be lost if the fucoidan and mineral components were washed away with washing. The experiment compared the amount of refined fucoidan in Okinawa Mozuku with and without slime.
"Experimental result"
Okinawa Mozuku (without slimming) 150 g: 1.22 g of purified fucoidan (24.4% (w / dw))
Okinawa Mozuku (without slimming) 150 g: purified fucoidan 1.42 g (28.4% (w / dw))
In other words, as shown in the above results, even if the slime was removed, there was no change in the components of the purified fucoidan, and it was confirmed that the content of the fucoidan component did not change even when the mozuku was dried, powdered, or powdered. Was done.
[0007]
Thus, for example, as shown in Japanese Patent Application Laid-Open No. 1-128771, there is a quality improvement method of mozuku, in which raw mozuku is rubbed and treated with salt, washed with water to remove slime on the mozuku surface, and then dried. As a result, a dried mozuku without slime can be obtained, and by throwing it into water, it can be returned to a raw mozuku without slime.
[0008]
However, in the above-described method for improving quality of Mozuku, 100 to 1 kg of salt is consumed per 1 kg of mozuku per one treatment. For this reason, the drying cost increases, and not only the surface of the raw mozuku but also the inside of the mozuku are removed. Thereby, there is a problem that even the fucoidan component and the mineral component inside the mozuku without slimming are removed.
[0009]

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a first embodiment of a method and an apparatus for producing dried mozuku of the present invention will be described with reference to FIGS. FIG. 1 is a process diagram showing a method for producing a dried mozuku, and FIG. 2 is a schematic diagram showing a washing / dehydrating process, a drying process, and each means used in the process. 3 is an external view of the slime removing means, FIG. 4 is an operational sectional view of the slime removing means, and FIGS. 5 and 6 are external views and operational sectional views of the dewatering means. 7 to 12 are diagrams showing the structure of the drying means, the operation control device, and the operation thereof.
[0029]
The method for producing dried mozuku of the present invention will be described including the pretreatment step. First, as shown in FIG. 1, the harvested original algae M1 is weighed 3 for each fixed amount. The raw algae M1 is inverted into the raw material tank 5 and supplied to the washing machine 9 by the screw 7 in the raw material tank 5, where it is washed and dirt is removed. The washed original algae M1 is sent out to the visual sorter 11 by a carry-out conveyor, and is sorted by an operator. After that, the selected raw mozuku M2 is fed by a pump 17 via a drainer 13 and a hopper 15 to a drying / washing machine (slime removing means) 20 as a washing / dewatering step, as shown in FIG. Then, the slime, which is a viscous substance adhering to the surface, is cleaned. The water attached to the surface of the washed raw mozuku M3 after the washing is removed by a centrifugal dehydrator (dehydrating means) 30 to become a dehydrated raw mozuku M4.
[0030]
Subsequently, in the drying step, after the dehydrated raw mozuku M4 is spread on the upper surface of the drying tray 43, it is placed in the dryer (drying means) 40 and air-dried with hot air H at 50 to 80 ° C. At this time, since the surface of the dehydrated raw mozuku is not slimy and has good air permeability, the passage of hot air is good and the air-permeable drying is reliably performed. Further, the surface temperature of the dehydrated raw mozuku does not rise to 60 ° C. or more due to latent heat of evaporation. Therefore, the mozuku does not discolor and does not become soft, so that when it is returned to water, the original texture can be obtained. The drying degree is generally set to a water content of 14% or less, but is preferably set to a water content of 3 to 11%, more preferably a water content of 3 to 7%. Stop and dry mozuku M5 is obtained. This dried mozuku M5 is packaged in a fixed amount 50 to be a product. Here, the water content is a percentage of the water content (kg) contained in 1 kg of the material.
[0031]
According to the method for producing dried mozuku, the raw mozuku is washed and dehydrated, after removing the surface of the raw mozuku as a raw material by washing, the centrifugal dehydration is used to remove the water adhering to the surface of the raw mozuku. Since the surface of the dehydrated raw mozuku is not slimy and has good air permeability, the passage of hot air is good. Therefore, since the drying is performed with the hot air H at 50 to 80 ° C., the drying speed is increased, and the drying cost is reduced. In addition, when returning to the raw mozuku, water can permeate quickly, and the slimming component is exposed to the surface from inside the mozuku, returning to a slimy raw mozuku state. For this reason, even if it is put in three tablespoons of vinegar, the texture of the original raw mozuku can be obtained. Further, the fucoidan component and the mineral component which are abundantly present in the slimming are not lost.
[0032]
In addition, the dried mozuku dried by the above method exhibits its effect when powdered as a raw material for cosmetics because the fucoidan component and the mineral component are present inside the mozuku. Also, when processed into powdered mozuku or crushed mozuku and used as a food material, it becomes a food material rich in fucoidan and mineral components.
[0033]
The outline of the manufacturing apparatus 100 used in the method for manufacturing the dried mozuku is as shown in FIG. Hereinafter, the detailed configurations of the drying and washing machine (slime removing means) 20, the centrifugal dehydrator (dehydrating means) 30, and the dryer (drying means) 40 will be described.
[0034]
As shown in FIGS. 2 to 4, the configuration of the drying and washing machine (slime removing means) 20 is as follows: a water tank 21 for storing a mixed solution WO obtained by mixing raw mozuku M2 and water W; And a stirring circulator 23 for sucking up and stirring the mixed solution WO. The stirring circulator 23 includes a half-opened cylindrical body 23A, a screw body 23B vertically arranged inside the cylindrical body 23A, a motor 23C for rotating and driving the screw body 23B, two pulleys 23D and 23E, and a belt 23F. In addition, a drain pipe 24 and an on-off valve 25 are provided in a lower part of the water tank 21 to drain the water W after being slimmed.
[0035]
With the configuration of the above-mentioned drying and washing machine (slime removing means) 20, the mixed solution WO of the raw mozuku M2 and the water W put in the water tank 21 rotates the screw body 23B by the activation of the motor 23C. The mixed solution WO is sucked from the suction port 26 provided at the bottom and discharged from the upper discharge port 27, and the suction / discharge action is repeatedly performed. At this time, the raw mozuku M2 in the mixed liquid WO sucked into the cylindrical body 23A rises while being stirred by the rotation of the screw body 23B, and the slime attached to the surface is separated.
[0036]
Therefore, only the slime adhered to the surface of the raw mozuku is reliably and quickly removed while being stirred with water by the stirring circulator. However, the slimming components in the raw mozuku are not removed. Therefore, the slimming component in the mozuku remains, and the fucoidan component and the mineral component are not lost.
[0037]
The configuration of the centrifugal dehydrator (dehydrating means) 30 includes, as shown in FIGS. 2, 5 and 6, an outer cylinder 33 and a mesh cylinder 35 disposed in a fixed cylinder 31. A rotating drum 37 is supported rotatably about a vertical axis V. The rotating body 37 is connected to a motor 39 serving as a rotation drive source, and is configured to rotate at high speed. An opening / closing lid 32 is pivotally supported on the upper part of the fixed cylindrical body 31.
[0038]
Thus, after a fixed amount of the washed raw mozuku M3 is put into the rotating drum 37, the rotating drum 37 can be rotated at a high speed to centrifugally dehydrate the raw mozuku. Thus, dehydrated raw mozuku M4 is obtained. Water is reliably and quickly removed from the raw mozuku from which the surface has been removed, and the slick component in the raw mozuku is not removed.
[0039]
As shown in FIGS. 2 and 7 to 10, the dryer (drying means) 40 arranges a plurality of drying trays 43 on which a dehydrated raw mozuku M4 to be dried is placed on a shelf 41 in a drying cabinet. H is passed through each of the drying trays 43 and air-dried. First, the hot air H is supplied to the dryer (drying means) 40 by blowing the outside air E to the heat exchanger 201 by the blower blower 203, where heat exchange with the steam S supplied from the boiler B is performed. The hot air H is supplied from the tube 205. In the dryer (drying means) 40, the exhaust hot air H1 used for drying is sucked from the exhaust pipe 206 by an exhaust blower and exhausted to the outside air.
[0040]
The detailed structure of the dryer (drying means) 40 will be described mainly with reference to FIGS. The housing 45 is provided with four independent box-shaped drying cabinets 41 in a vertical arrangement. The drying cabinet shelf 41 is provided with an opening on the front side of the housing 45 so that the drying tray 43 can be taken in and out, and an inspection door 47 for closing the opening. An operation lever L of the in-machine damper 49 is provided on the right side. As shown in FIG. 10, the in-machine damper 49 is pivotally provided on a side of each shelf 41 in the drying cabinet so that the amount of hot air H introduced can be adjusted.
[0041]
Pipes P1, P2, P3, and P4 penetrate through the four corners of the top part 45A of the housing 45, and are disposed in a vertical posture. Opening / closing valves V1, V2, V3, and V4 are provided in the respective pipes P1, P2, P3, and P4, and are opened and closed by electromagnetic drivers D1, D2, D3, and D4. The upper part of each of the pipes P1 and P2 is connected to a cylindrical pipe 205, and the upper part of each of the pipes P3 and P4 is connected to an exhaust pipe 206. Thus, when the on-off valve V1 of the pipe P1 and the on-off valve V4 of the pipe P4 are open, the hot air H enters the cavity 51 in the housing from the pipe P1, and enters from the in-machine damper 49 of the shelf 41 in each drying cabinet. Downward air is blown from the upper side to the lower side of the drying tray 43 inside the drying cabinet 41.
[0042]
Then, the air is discharged from the hollow portion 53 to the exhaust pipe 206 via the pipe P4. Also, when the on-off valve V2 of the pipe P2 and the on-off valve V3 of the pipe P3 are open, the hot air H enters the cavity 53 in the housing from the pipe P2, and the lower side of the drying tray 43 of each drying cabinet shelf 41. It is a downward blow that escapes upward from. The hot air H that has entered the inside of the drying cabinet 41 from the lower side of each drying tray 43 passes through the in-machine damper 49 into the hollow portion 51 and is discharged to the exhaust pipe 206 via the pipe P3.
[0043]
As described above, the hot air H supplied from the cylindrical tube 205 is supplied to each shelf 41 in the drying cabinet so that the hot air path is directed upward and downward to the drying tray 43 as shown in FIGS. The opening and closing operation of each of the on-off valves V1, V2, V3, V4 is driven to open and close by electromagnetic drivers D1, D2, D3, D4 connected thereto so as to blow air. Thus, the dehydrating mozuku M4 spread on the upper surface of the drying tray 43 is subjected to air-flow drying by inverting the hot air H between the upward blowing and the downward blowing. As shown in FIG. 11, the electromagnetic drivers D1, D2, D3, and D4 are controlled by an operation control device 200 that controls the operation of a dryer (drying means) 40 of the drying mozuku manufacturing apparatus 100. The method and the apparatus for producing a dried mozuku according to the present invention may be configured such that the hot air H is fixed to either the upward or downward blast to perform the permeable drying. In this case, the drying time is set longer than the above.
[0044]
An embodiment of the operation control device 200 will be described. First, the heat exchanger 201 that supplies the hot air H to the dryer (drying means) 40 includes a burner B2 that uses the water of the boiler B1 as steam S, and a heat exchange pipe P that is disposed inside the heat exchanger 201 to supply outside air E to the heat exchanger 201. And a blower blower 203 for blowing air. Then, the temperature sensor S1 is disposed in the tubular tube 205 on the hot air discharge side of the heat exchanger 201. The output of the temperature sensor S1 is input to a comparator 207 with a temperature setting device (set at 50 to 80 ° C.) S2, and a comparison signal output from the temperature sensor S1 is input to a temperature control unit 209, and the hot air setting temperature (50 The heating power of the burner B2 is adjusted and controlled so that the temperature becomes about 80 ° C.
[0045]
Further, the operation control device 200 includes a timer T1 and a hot air direction switch 220. With this, the electromagnetic drivers D1 to D4 of the four on-off valves V1 to V4 arranged in the dryer (drying means) 40 are changed in the direction of the hot air for air drying at a predetermined time interval (t) set by the timer T1. Energize and de-energize alternately upside down.
[0046]
The drying time by the dryer (drying means) 40 is set, for example, by a timer T2 at a time when the moisture content becomes 5%. The operation of the dryer (drying means) 40 is stopped by the expiration of the timer T2. The drying time is determined by, for example, setting the time at which the water content becomes 5% by using the timer T2, and confirming that the drying has been sufficiently performed by visual inspection to stop the operation of the dryer (drying means) 40. May be. The operation control unit 213 includes a start / stop switch So and is also connected to the temperature control unit 209 to control the operation / stop of the burner B2.
[0047]
According to the operation control device 200, as shown in the operation control time chart shown in FIG. 12, the operation of the dryer (drying means) 40 is controlled. First, the treatment time is set so that the water content is, for example, 5%, the hot air setting temperature is 80 ° C., and the dehydrated mozuku M4 having a water content of about 97% is spread on the upper surface of the drying tray and placed in the dryer 40. . Subsequently, hot air H at 50 to 80 ° C. is fed into the dryer to start air-permeable drying. During this operation, the direction of the hot air to be air-dried is alternately inverted up and down at a predetermined time interval (t) set by the timer T1. At this time, since the surface of the dehydrated raw mozuku M4 is not slimy and has good air permeability, the passage of hot air is good, and the air drying can be efficiently promoted. Further, the product temperature of the dehydrated raw mozuku does not rise to 60 ° C. or more due to latent heat of evaporation during air-permeable drying. For this reason, the dehydrated raw mozuku M4 does not boil, and there is no deterioration such as discoloration or softness. Eventually, the timer T2 times out, the dryer 40 is stopped, and a dried mozuku M5 having a water content of 5% is obtained.
[0048]
Next, an embodiment of a method for producing a dried mozuku using the above-described apparatus 100 for producing a dried mozuku will be described. After 1 kg of the raw material of the harvested raw mozuku M1 is pre-processed, it is put into a drying / washing machine (slime removing means) 20 which is a washing / dehydrating step to wash the slime which is a viscous substance adhered to the surface. . The water attached to the surface of the washed raw mozuku M3 after the washing is removed by a centrifugal dehydrator (dehydrating means) 30 to become a dehydrated raw mozuku M4. The raw material after washing and dehydration has a water content of 97.4% W. B, weight 1.143 kg.
[0049]
Subsequently, in the drying step, after the dehydrated raw mozuku M4 is spread on the upper surface of the drying tray 43, the dried mozuku M4 is placed in the dryer (drying means) 40 and air-dried with hot air H at 50 to 80 ° C. At this time, since the surface of the dehydrated raw mozuku is not slimy and has good air permeability, the passage of hot air is good and the air-permeable drying is reliably performed. The treatment time is 2.5 hours, the dryness is 7% and the weight is 0.032 kg. During the above treatment, the surface temperature of the dehydrated raw mozuku does not rise to 60 ° C. or more due to latent heat of evaporation. Therefore, there is no discoloration of the mozuku, the mozuku does not become soft, and a thin fibrous dried mozuku M5 is obtained.
[0050]
When the dried mozuku M5 was immersed in water and returned to the raw mozuku, the texture was examined by several monitors, and it was confirmed that the original raw mozuku had a slimy and crunchy texture. .
[0051]
As described above, according to the method and the apparatus for producing dried mozuku of the present invention, the drying speed of raw mozuku is high and the drying cost is low. In addition, when returning to raw mozuku, water can permeate quickly, the slimming component is exposed to the surface from inside the mozuku, the original texture can be obtained, and the fucoidan component and the mineral component are not lost.
[0052]
In addition, the dried mozuku produced by the method for producing dried mozuku of the present invention has abundant fucoidan and mineral components therein, and exhibits its effect when powdered into a raw material for cosmetics. . Also, when processed into powdered mozuku or crushed mozuku and used as a food material, it becomes a food material rich in fucoidan and mineral components.
[0053]
Next, a second embodiment of the present invention will be described with reference to FIGS. In the case of the second embodiment, a freezing step is added between the washing / dewatering step and the drying step in the first embodiment. That is, after the dehydrated raw mozuku is spread on the upper surface of the drying tray, a step of performing a freezing treatment and freezing is performed.
[0054]
In other words, the apparatus for producing dried mozuku comprises a slime removing means for cleaning and removing surface maturation of raw mozuku as a raw material, a dehydrating means for removing water adhering to the surface of the raw mozuku from which the surface is removed, and an upper surface of the drying tray. The freezing means for freezing the dehydrated raw mozuku spread on the surface of the drying tray and the frozen dehydrated raw mozuku spread on the upper surface of the drying tray are placed in a dryer, and hot air is sent into the dryer and air-permeable and dried to form a dried mozuku. Means. The configuration thereof is the same as that of the first embodiment except for the refrigeration means, and the description is omitted. As the freezing means, for example, a freezer is used, but the present invention is not limited to this. For example, a conveyor-type freezing device may be used.
[0055]
Then, dried mozuku is obtained through the steps shown in FIG. First, as a pretreatment step, raw mozuku (raw algae M1), which is a raw material, is washed 101, and then visually inspected 103 to remove impurities and contaminants, thereby obtaining sorted raw mozuku M2. Then, immediately, the production process of the dried mozuku of the present invention is started. If necessary, the raw mozuku M2 may be frozen 105 for storage and then thawed 107 when dried. In this way, by freezing 105, it is possible to keep the storage for an arbitrary time. In addition, before performing the manufacturing process of the dried mozuku of the present invention, washing 109 is performed as necessary. However, this step is not essential.
[0056]
Next, the process enters the method for producing dried mozuku of the present invention. After the surface of raw mozuku M2 serving as a raw material is washed and removed 111, water adhering to the surface is removed by centrifugal dehydration 115 to obtain dehydrated mozuku M3. Washing and dewatering are performed. Next, after the dehydrated raw mozuku M3 is spread on the upper surface of the drying tray, a freezing process is performed by performing a freezing treatment and then frozen 117. Next, the frozen dehydrated raw mozuku M3 spread on the upper surface of the drying tray is placed in a dryer. Drying 119 is performed in which the air is dried with hot air at 50 to 80 ° C., and dried mozuku M5 is obtained.
[0057]
In the case of the above-described apparatus and method for producing dried mozuku, a freezing step is added between the washing / dehydrating step and the drying step. When the dried dehydrated raw mozuku on the upper surface of the drying tray is dried by the above-mentioned drying step, it is considered that the drying time may take an extra time at a low temperature, but it has been found that the drying time is actually considerably shortened. FIG. 14 shows an example in which the degree of drying with and without freezing is compared under the same conditions as in the drying step shown in the first embodiment, and the elapsed time (minutes) of drying is plotted on the horizontal axis. The vertical axis shows the mozuku weight (kg) and shows the change. As a result, it took 120 minutes to dry 4,03 kg of mozuku to 0.25 kg without freezing, whereas, with freezing, 3,94 kg of mozuku dried to 0.24 kg. It can be seen that it took 100 minutes to dry and 120 minutes to dry to 0.2 kg. In other words, the drying time is faster by about 20 to 30 minutes when there is freezing. In the case of freezing, water drops fall 20 to 30 minutes after the introduction, and a water pool is formed under the dryer. The reason for this may be that the cell wall of the mozuku is destroyed by freezing, and when the mozuku is dried thereafter, moisture comes out from the inside of the destroyed cell wall (drip), and drying is accelerated. In addition, the frozen dehydrated raw mozuku M3, which is not frozen, has a relatively sticky sheet shape and has a slightly poor air permeability, whereas a thick and fluffy shape is used. Therefore, ventilation becomes easier during air-permeable drying, and drying can be performed in a short time. In addition, the dried dried mozuku also has a thick and fluffy shape, so it is easy to return the water permeability well when immersed in water and return to raw mozuku, or in a short time when returning as soup with hot water It can be returned.
[0058]
As described above, in the case of the present embodiment, not only the same effects as in the case of the above-described first embodiment can be achieved, but also air-permeable drying can be performed in a shorter time, and the manufacturing tact can be further reduced. High-quality dried mozuku that can be easily returned with water or hot water can be produced at a lower cost.
[0059]
The present invention is not limited to the above embodiments. For example, the operation of alternately inverting the hot air direction up and down at a predetermined time interval t by the switching operation of the duct may be a method of manual operation other than the automatic switching by the timer T. As described above, the air-drying method may be air-drying by supplying hot air from one direction, instead of the method of alternately turning upside down at predetermined time intervals t. Further, the configuration of each unit in the drying mozuku manufacturing apparatus 100 and the operation control apparatus 200 can be appropriately changed in design within the gist of the invention.
[0060]
【The invention's effect】
As described above in detail, according to the method and the apparatus for producing dried mozuku of the present invention, the drying speed of raw mozuku is increased, and high-quality dried mozuku can be produced at low cost. Also, when this product is returned to raw mozuku, water can quickly penetrate and the slimming components are exposed to the surface from inside the mozuku, returning to the state of slick raw mozuku, the original texture of raw mozuku can get. Further, the fucoidan component and the mineral component which are abundantly contained in the slimming are not lost.
[0061]
In the method and apparatus for producing dried mozuku of the present invention, a freezing means is added, and a freezing step is added between the washing / dewatering step and the drying step, so that the frozen dehydrated water on the upper surface of the drying tray is added. When the mozuku is dried by the above-mentioned drying step, air-permeable drying can be performed in a shorter time, the production tact can be shortened, and a high-quality dried mozuku that can be easily returned with water or hot water can be produced at a lower cost.
[0062]
Further, in the dry mozuku manufacturing apparatus of the present invention, a water tank for storing a mixed liquid obtained by mixing raw mozuku and water as a slime removing means, and a stirring circulator which is vertically provided on one side of the water tank to suck and agitate the mixed liquid. And slime attached to the surface of the raw mozuku is reliably and quickly removed while being stirred with water by the stirring circulator. However, the slimming components in the raw mozuku are not removed. For this reason, the slick component in the mozuku remains, and the fucoidan component and the mineral component in the slick are not lost.
[0063]
In the apparatus for manufacturing a dried mozuku of the present invention, the dewatering means includes an outer cylinder and a mesh cylinder arranged in the fixed cylinder, and the outer cylinder and the mesh cylinder are integrally rotated. However, when the raw mozuku placed in the net cylinder body is subjected to centrifugal dehydration, moisture on the surface of the raw mozuku from which the slime has been removed from the surface of the raw mozuku is reliably and rapidly removed. However, the slimming components in the raw mozuku can be left without being removed.
[0064]
Further, in the method for producing a dried mozuku of the present invention and the drying means, in the drying step, the direction of hot air to be air-dried with respect to the dehydrated raw mozuku spread on the upper surface of the drying tray is alternately turned upside down at predetermined time intervals. Thereby, the air-drying of the dehydrated raw mozuku on the upper surface of the drying tray is performed more efficiently, and a high-quality dried mozuku can be manufactured at low cost.
