Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Field of Application> The present invention relates to a humidifying device for a seaweed dryer.

<Prior art> In general, drying of seaweed is carried out by supporting the seaweed that has been shredded in a cage on a conveyor in a paper-making device, and transporting it into a drying room using a heat source installed adjacent to the drying room. The hot air is blown in by a heating machine having a fan and a fan, and the seaweed is dried by the hot air. When drying such seaweed, the humidity in the drying room is an important factor in obtaining high quality seaweed, and various measures have been taken to maintain an appropriate humidity.

For example, the humidity adjusting device disclosed in Japanese Patent Application Laid-Open No. 61-271967 is one example, and this device is equipped with a humidity detector and a temperature detector, and keeps the relative humidity constant by adjusting the exhaust volume of an exhaust fan and the temperature up and down. This device is said to lower the temperature when increasing the relative humidity in the drying chamber, and it is said to supply steam when increasing the absolute humidity.

It is true that relative humidity can be adjusted by temperature, but
Since the set temperature also has a certain limited range, it cannot be changed without limit, and the absolute humidity must be adjusted. The method for doing so is shown in the above-mentioned Japanese Patent Application Laid-Open No. 61-271967. Regardless of the technology, all conventional devices were devices that supplied steam.

<Problems to be Solved by the Invention> When drying seaweed, if a large amount of seaweed is stored in the drying chamber, the temperature may be changed up or down within a certain range due to the moisture held by the seaweed. Alternatively, it is possible to adjust the relative humidity in the drying chamber by opening and closing a ventilation fan. However, at the beginning and end of drying when there is not much seaweed in the drying room, there is a lack of moisture throughout, so it is necessary to add additional moisture. Conventionally, the method of adding this moisture was to supply steam as described above, but supplying steam requires a large-scale steam generator, and it takes a long time for the steam to rise, so a quick response is required. The drawback was that it was not possible.

It is an object of the present invention to provide a humidifying device which eliminates the above-mentioned drawbacks in steam supply, has small and simple equipment, and can quickly increase moisture content.

<Means for Solving the Problems> The above object of the present invention can be achieved by employing the following device. In other words, in a seaweed dryer consisting of a drying room installed in a building with ventilation holes and a heating machine placed adjacent to the drying room, a hot water boiler is installed in the building, and an upward opening is installed in the upper part of the outside of the drying room. A saucer is arranged, a pressure pump is attached to forcefully pump the hot water in the hot water boiler, a hot water supply pipe extending from the pressure pump is inserted into the saucer, and a portion of the hot water supply pipe is inside the saucer. This is a humidifying device for a seaweed dryer, characterized in that a required number of hot water spout holes are provided through the seaweed dryer.

<Embodiments and Effects> The present invention will be described in detail below with reference to drawings showing embodiments.

An embodiment of the present invention is shown in FIG.
In the figure, 1 is a building, 2 is an exhaust hole and has an exhaust fan, 3 is a drying room, 4 is a heating machine, 5 is its suction fan, 6 is a hot water boiler, 7 is a pressure pump, and 8 is a hot water The supply pipe, 9 is a saucer, and 10 is a hot water spout hole inserted through the hot water supply pipe.Details of this part are shown in FIG. 2, but normally, a spout nozzle 11 is attached to the hot water spout hole 10 for use.

In the humidifying device of the present invention having such a configuration, the humidity and temperature are constantly detected by the humidity sensor and temperature sensor disposed in the drying chamber, and the drying of the seaweed is carried out by adjusting the temperature and opening/closing the exhaust hole 2. As long as the relative humidity can be adjusted within a range that does not interfere with the process, there will be less seaweed in the drying chamber.If the absolute moisture content in the drying chamber is insufficient due to other factors, that is, the temperature is at the limit that will cause problems in drying the seaweed. If the relative temperature is still insufficient even if the temperature has been raised to
By operating the pressure pump 7, the hot water in the hot water boiler 6, which always stores hot water at the required temperature, passes through the hot water supply pipe 8 and rises to the saucer 9 installed on the roof of the drying room 3. , the hot water is ejected from a hot water spout hole 10 provided through the hot water supply pipe 8 in the saucer 9. Then, the spouted fine granular hot water, that is, mist hot water, is taken into the heating machine 4 by the suction fan 5 of the heating machine 4, humidified there again, and sent into the drying chamber 3 together with the heated air, where the required amount is It supplies moisture. This spouting of hot water continues until the amount of moisture determined by the humidity sensor, temperature sensor, and their controller installed in the drying chamber 3 is supplied, and when the required amount of moisture is supplied, it automatically Make sure it is stopped.

In addition, in Figures 1 and 2, 12 indicates that when hot water is spouted out, there are areas near the nozzle where the hot water tends to form larger drops than necessary and simply fall. If hot water enters the heating machine 4 and further into the drying room 3 as it is, it will damage the seaweed, so this large droplet of water is received in a saucer 9 and the water discharge pipe is for discharging the water stored there.

<Effects of the Invention> As described above, according to the apparatus of the present invention, when drying seaweed, the absolute amount of moisture in the drying chamber is insufficient, and in order to supply moisture, hot water is sprayed in the form of a mist inside the building.
Since this water is introduced into the drying chamber through the heating fan, the necessary moisture can be quickly supplied using a small-scale device. In other words, it is easy to constantly store the required amount of hot water maintained at the required temperature in a hot water boiler, considering that the amount of water required for this type of equipment is not very large, and this is compared to the case of steam supply. In this way, the supply equipment can be small-scale and can respond quickly. Furthermore, since hot water is supplied, the sensible heat content of the hot water does not lower the temperature of the system and is more effective than when cold water is supplied.
