BACKGROUND OF THE INVENTION
The present invention relates to a laver drying method and a laver drying apparatus using a building including an auxiliary heater and a duct.
[0002]
[Prior art / problems to be solved by the invention]
The current drying of the seaweed is carried out by a fully automatic laver dryer installed in the building, this type of laver dryer (referred to as a dryer), which has a total length of about 10 m. An example of this will be briefly described with reference to FIG. 7. A heating chamber installed in a building installs air outside the building (outside air) and air inside the building (inside air) on the heating chamber. After sucking in through a suction fan, hot air is generated through heat exchange, and the hot air is sent to a drying chamber to dry fresh seaweed (paper laver). This is a structure in which humid air (warm air in the air circulation zone, which is warm air) discharged from the drying chamber is exhausted from the inside air outlet provided in the building. In addition, since a part of this warm air needs an appropriate temperature and humidity at the time of the above-mentioned drying, it is sucked together with the outside air through the suction fan and enters the drying chamber. follow. That is, the raw laver in the drying chamber is dried while reciprocating this air flow and the temperature and humidity control of the heating chamber and reciprocating in the drying chamber over several hours. The temperature and humidity of the air flowing through the sea have a significant effect on the drying of fresh seaweed. In addition, the inside air of the building fluctuates greatly depending on the weather such as rain, wind, snow, etc., which directly affects the temperature and humidity in the drying chamber, which is detrimental to the drying of fresh seaweed. For example, the following can be considered. In other words, if the temperature and humidity are uneven, there is an adverse effect that a part of the seaweed does not dry, the so-called swell, the generation of spiders that appear to be cloudy with no gloss, or the harmful effect of rapid drying, the so-called Problems such as deterioration in quality due to Chichi nori due to drought that occurs due to uneven shrinkage, and deterioration in the value of nori due to this harmful effect occur. Another cause of this uneven temperature and humidity is that the air flow varies depending on the air gaps in the building and the shape of the roof and walls. To adjust the temperature. The applicant has filed many proposals related to this. For example, JP-A-2-60570 can be mentioned. However, the current situation is not enough.
[0003]
As a part of solving this problem, some means tend to be adopted, and the present applicant has conducted various experiments. An example will be described. In (1) (not shown), temperature / humidity sensors are provided in a plurality of locations in the drying chamber (for example, each is installed so as to be roughly divided into two before and after the drying chamber), and based on the measured values. There is a means to keep the humidity in the drying chamber uniform by ventilating the building. However, this means that there are two measurement locations, so it is difficult to keep the humidity in the drying chamber uniform, and the uniformity of temperature and humidity is disturbed by the inflow of cold outside air during ventilation, and the change becomes large. This leaves various problems. (2) is a means that the applicant of the present invention repeatedly conducted an experiment as an improvement plan of (1), and a certain result was obtained. An outline thereof is shown in FIG. That is, there is a tendency that a means for using the auxiliary heater arranged in the building and the existing heating chamber together (referred to as a combined means) is employed. This combined means introduces primary air (outside air) into the auxiliary heater, and introduces the entire amount of outside air required from the outside air inlet of the building (inhales) and flows through the air circulation zone (air exhausted from the drying chamber). Part of the moist warm air is introduced (taken in) from the inside air suction port of the auxiliary heater and converted into warm air through heat exchange. This hot air is supplied to the entire heating chamber via a duct arranged on the floor of the building, converted into hot air through heat exchange in the heating chamber, and then the hot air path provided in the heating chamber is changed. It is a means to supply to a drying chamber via. However, this combined means has the following disadvantages. : (1) Many air outlets provided in the duct are separated from the suction port of the heating chamber, and the warm air from the auxiliary heater is easily diffused, and the diffusion of the warm air and / or arrangement of the duct Depending on the size, etc., there is no guarantee that the heating chamber can be reliably or appropriately supplied to the suction port. : (2) The introduction of a large amount of outside air into the auxiliary heater sometimes leads to a change in the air flow in the building and destroys the balance. (3) As a result of the supply of hot air with uneven temperature to the drying chamber, the quality deteriorates, and for example, dry seaweed, cracks, gloss unevenness, and scratches occur. : (4) Since the outside air is introduced into the auxiliary heater in the entire amount (the same amount as the ventilation amount), there is a problem that a large capacity and a heat source are required. : (5) Invite the equipment to increase in size, and there are situations where it cannot be installed due to the increase in size, or the space at the site is not secured, and installation work is difficult, and installation costs are high. There are issues such as.

Subsequently, the hot air generated in this heating chamber (in some cases, individually in the heating chamber) is transferred to the entire drying chamber (in some cases, in the heating chamber individually) via a hot air path that connects the heating chamber and the drying chamber. To supply). Therefore, since the hot air in an optimal state is supplied to the drying room, it is possible to substantially eliminate the drying of fresh seaweed and eliminate the occurrence of defective products such as seaweed, cracks, gloss unevenness, chijimi, and terry of dry seaweed, or There are practical benefits such as the expectation of quality improvement. The point of the present invention detects the humidity of the air above the heating chamber (external air introduction location, warm air introduction location from the drying chamber and outlet from the duct) via humidity sensors provided at several locations. Then, an appropriate amount of hot air is supplied from the duct to the heating chamber in a place with high humidity, hot air is generated in this heating chamber, and this hot air is supplied to the drying chamber to supply temperature and / or humidity (hereinafter referred to as temperature, etc.). )).
