Description

[Detailed explanation of the invention] This invention uses a clean gas with a lot of water produced by a combustion reaction, i.e. water vapor, as fuel, and when the atmosphere inside the dryer box becomes dry, this clean combustion exhaust gas is used as a fuel. The inside of the dryer box is introduced directly into the dryer box to moderately humidify the inside of the dryer box with the twisting product water contained therein, and to obtain a moist dried seaweed product without overdrying. A horizontal fuel pipe is installed at the inner bottom of a hot air chamber separated from the drying room, and the inlet of the fuel pipe is connected to a long-flame gas burner, and the smoke exhaust from the fuel pipe is connected to a long-flame gas burner. The opening is connected to an exhaust pipe built along the top of the dryer box via a smoke pipe serving as a heat exchanger, and the exhaust pipe is connected to a smoke exhaust pipe whose upper opening communicates with the outside air. The pipes are connected to each other, and the lower side of the exhaust pipe is connected to a plurality of communication ports that open downward toward the hot air chamber, and the communication ports are used to communicate with the hot air chamber through the combustion gas introduction pipe. communicated with a discharge port opened toward the discharge port, and the discharge port is provided with a control plate and a blower,
This is an improvement of a continuous seaweed dryer in which a control plate is also provided on the smoke exhaust pipe, and the control plate provided on the exhaust port opening toward the hot air chamber and the control plate provided on the smoke exhaust pipe are opened. The dryer temperature is proportionally controlled by a humidity controller and a control motor controlled by a control panel. According to this invention, the atmosphere inside the dryer box is over-dry. When the condition is reached, clean combustion exhaust gas containing combustion generated water is directly introduced into the dryer box, and the twisted and fired water contained therein moderately humidifies the inside of the dryer box to ensure drying of the moist nori. In addition, when the inside of the dryer box is overhumidified due to water vapor generated from raw seaweed, the dryer box can be removed without introducing combustion exhaust gas directly into the dryer box. The drying process is carried out efficiently only by indirect heating through the heat exhaust pipe, and when the inside of the dryer becomes overly dry, it is controlled by the humidity controller and control panel. It is often useful to be able to perform appropriate humidification by directly introducing combustion exhaust gas by proportionally controlling the opening degree of a switching setting control plate linked to a control motor.

Conventional continuous seaweed dryers are known to burn fuel oil in fuel pipes and heat it indirectly via a heat exchanger, but in this case, the atmosphere inside the dryer is extremely dry. Therefore, in the process of drying and finishing the seaweed, it is overdried, resulting in the product nori cracking or becoming crumbly.

On the other hand, this invention eliminates the drawbacks of the conventional method and uses clean combustion exhaust gas as fuel, which is characterized by a large amount of water, that is, water vapor produced by the combustion reaction. When the atmosphere inside the box becomes over-dry, clean combustion exhaust gas is directly introduced into the dryer box, and the water contained in the dryer box is used to moderately humidify the inside of the dryer box, preventing over-drying. According to this invention, when the atmosphere inside the dryer box becomes over-dry, clean combustion exhaust gas containing combustion generated water is directly pumped into the dryer box. When introduced, the inside of the dryer box can be properly humidified by the twisting product water contained therein, and the moist seaweed can be dried. When the humidity is high, the combustion exhaust gas is not introduced directly into the dryer box, but is discharged outside the dryer box, and the drying process is performed efficiently by indirect heating only through the smoke pipe for heat exchange. If this is done and the inside of the dryer box becomes over-dry,
Proportional control is performed by a switching setting control board linked to a control motor controlled by a humidity controller, open side panel, and combustion exhaust gas can be directly introduced to achieve appropriate humidification.

In addition, in a seaweed drying device consisting of a seaweed drying chamber and a warm air generation chamber, a pipe body is inserted into the hot air generation chamber to send high temperature combustion gas from a gas burner, and the high temperature combustion gas is mixed with outside air to dry the seaweed. In a seaweed drying apparatus that is provided with a fan that feeds into the room and that exchanges heat with the high-temperature combustion gas in the pipe body, the pipe body that feeds the high-temperature combustion gas is provided above the hot air generation chamber, and A fan for mixing high-temperature combustion gas and outside air is provided in the hot air generation chamber below the hot air generation chamber, and a damper for regulating hot air is provided in the tube provided above the hot air generation chamber, and the damper and the damper below the hot air generation chamber are provided. It is a prior art application 153579/1986 to interlock the installed fans.
No. (Utility Model Application Publication No. 57-76496) is planned as a seaweed drying device.

However, the damper as a control board in this prior application design is a humidity controller, as in the invention of this application.
Since it is not linked to the control motor controlled by the control panel, this prior application design cannot proportionally control the opening of the damper when the inside of the dryer becomes overly dry. Humidification cannot be performed.

On the other hand, according to the invention of this application, the hot air is communicated with an outlet opening toward the inside of the hot air chamber, and the outlet is provided with a control plate and a blower.
A continuous seaweed dryer in which a control plate is also provided on the smoke exhaust pipe, and the opening degree of the control plate provided on the exhaust port opening toward the hot air chamber and the control plate provided on the smoke exhaust pipe is Respectively,
Proportional control is performed by the control motor controlled by the humidity regulator and control panel, so when the inside of the dryer box becomes overdry, the control motor controlled by the humidity regulator and control panel Proportional control is performed by interlocked switching setting control plates, and combustion exhaust gas can be directly introduced to perform appropriate humidification, which is often useful.
