TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for drying laver using a built-in heating chamber and a laver drying apparatus.
[0002]
[Prior art]
At present, drying of laver is carried out by installing a fully automatic laver dryer with a total length of about 10 m installed in a drying building (mainly, a drying chamber equipped with a laver cage, transport means, etc., or a heating chamber equipped with a suction fan, a kettle, etc. ). An example of this will be briefly described with reference to FIG. 8. In the heating chamber of this dryer, air outside the building (outside air) and air inside the building (inside air) are sucked through a suction fan. . This air is heated by a kettle, a heater, etc. (hereinafter referred to as a kettle) provided in the heating chamber to become high-temperature air (hot air), supplied to a drying chamber, and dried in the drying chamber. I do. The humid air (wet warm air in the air circulation zone: hereinafter, used warm air) discharged from the drying chamber is exhausted to the outside of the building from an inside air discharge port provided in the building. Further, since a proper temperature and humidity are required in the drying chamber, a part of the warm air is sucked again through the suction fan together with the outside air, and follows the same way as described above. That is, the raw nori in the drying chamber is dried during several round trips in the drying chamber for about two hours in the control of the amount or flow of hot air, the control of the pot, and the inside and outside air. The temperature and humidity of the air flowing through the drying chamber have a great effect on the drying of the raw seaweed.
[0003]
Therefore, the adverse effect of partly drying the seaweed due to uneven temperature and humidity (for example, generation of slime, cloudy cloud that looks cloudy without gloss), or the adverse effect of rapid drying (for example, uneven shrinkage) Of the seaweed caused by wrinkles, etc.), adverse effects (for example, tearing, perforation, etc.) due to overdrying, and problems such as deterioration of the quality and value of the seaweed due to the adverse effects. It is considered that other causes of the temperature and humidity non-uniformity that cause this problem include a draft in a building and a difference in the flow of air due to a difference in the shape of a roof or a wall.
[0004]
As a part of solving this problem, several means are adopted, and an example will be described. (1) In a drying room, temperature and humidity sensors are provided at a plurality of locations (for example, each of them is installed so as to be divided into approximately two parts before and after the drying room), and based on the measured values, ventilation of a building or the like is performed. For keeping the humidity in the drying chamber uniform, for example, there is JP-A-10-257870. However, the problem with this means is that it is difficult to keep the humidity in the drying room uniform because there are two measuring points, and the uniformity of temperature and humidity is disturbed due to the inflow of cold outside air during ventilation. Problems such as the inability to control the temperature and humidity of the heating chamber due to a large change in disturbance remain. (2) is a temperature and humidity control system in which the building is divided into partitions and individually controlled, for example, a partition plate is provided around the dryer to individually control the temperature and humidity, and the used temperature is relatively uniform. The purpose is to introduce warm air into the heating chamber and reuse an appropriate amount of the warm air. For example, there is Japanese Utility Model Laid-Open No. 4-55290. However, the problem with this means is that the temperature and humidity management of the heating chamber often depends on the outside air, and the current situation is that sufficient results have not always been achieved. (3) Introduce primary air (outside air) and a part of used warm air into the auxiliary heater, exchange heat and convert it to warm air, and then distribute the warm air to the floor of the building. It is supplied to the entire heating chamber via a tact and converted into hot air in the heating chamber. The hot air is supplied to the drying chamber. The problem with this means is that (3-1) a large number of outlets provided in the tact are separated from the suction port of the heating chamber, so that the warm air from the auxiliary heater is easily diffused. Due to the diffusion and / or arrangement and size of the tact, there is no guarantee that the heat can be supplied to the suction port of the heating chamber reliably or in an appropriate amount. (3-2) Since the outside air is sucked (introduced) in the entire amount (the same amount as the ventilation amount) into the auxiliary heater, a change (turbulence) in the flow (airflow) such as air and warm air in the building is caused, and the balance is broken. Therefore, problems such as the occurrence of various adverse effects, or the occurrence of adverse effects due to the need for a large capacity and a heat source, an increase in the size of the device, an increase in the installation space, and the like, and the problem of difficulty in installation occur. is there.
