Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to a seaweed drying device that eliminates variations in drying in the lateral direction of a seaweed drying chamber and enables uniform drying.

(Background of the Invention) A seaweed drying device sends air warmed in a heat exchange chamber into a drying chamber, and transfers the air to the seaweed spread on a seaweed cage that is conveyed along a conveyance path provided in the drying chamber. The nori is dried by applying warm air to it. However, the heat exchange chamber of this type of nori drying equipment is generally placed on the side of the drying chamber, and the warm air generated here is sent into the drying chamber from the side.
There is a problem in that the closer the seaweed is to the heat exchange chamber, the more the hot air hits it, resulting in uneven drying in the lateral direction of the drying chamber.

(Objective of the Invention) The present invention has been made in consideration of the above circumstances, and an object of the present invention is to provide a seaweed drying apparatus that can eliminate variations in drying in the lateral direction of a drying chamber.

(Summary of the Invention) The present invention provides a porous member disposed below a conveyance path made of an endless chain or the like that circulates in a drying chamber, a partition member disposed below the porous member, and a partition member disposed below the porous member. It is installed obliquely with an upward slope from the heat exchange chamber side provided on the side of the drying chamber toward the other side of the drying chamber, and its starting end opening is communicated with the heat exchange chamber. With this configuration, the warm air sent into the drying room from the side is blown up more evenly towards the seaweed spread in the seaweed cages transported along the transport path, thereby drying it. This eliminates variations in drying in the horizontal direction of the chamber, allowing for uniform drying.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a seaweed drying chamber, and an endless chain 2 constituting an endless conveyance path is installed in the drying chamber 1. In FIG. Reference numeral 3 denotes a holder to which a seaweed cage 4 is attached, and the holder 3 is loaded onto the endless chain 2 and conveyed along the endless chain 2 within the drying chamber 1 by the circulation of the endless chain 2. Reference numeral 5 denotes a heat exchange chamber provided on the side of the drying chamber 1, and a heat exchange duct 6 is disposed inside the heat exchange chamber. The heat exchange duct 6 is connected to a burner (not shown), and air heated by the burner circulates within the heat exchange duct 6. 7
is an outside air intake port provided on the side wall of the heat exchange chamber 5, and the cold air sucked into the heat exchange chamber 5 from the intake port 7 is heated by the heat radiation of the heat exchange duct 6 and becomes warm air. and fed into the drying chamber 1 from the side.

Reference numerals 8 and 8 are plate-shaped porous members in which a large number of ventilation holes 9 are formed, and are disposed below the endless conveyance path made up of the endless chain 2. 10, 10 are plate-shaped partition members disposed below the porous members 8, 8, and are installed obliquely with an upward slope from the heat exchange chamber 5 side to the other side of the drying chamber 1, The starting end openings 15, 15 communicate with the heat exchange chamber 5. The air (warm air) warmed in the heat exchange chamber 5 ascends through the air circulation chamber 14 and further passes through the partition member 1.
It enters between the partition members 10, 10 and the porous members 8, 8 from the starting end openings 15, 15 of 0, 10, blows up from the ventilation holes 9 of the porous members 8, 8 to the spaces A, B,
The seaweed m spread on the seaweed cages 4 conveyed in the spaces A and B is dried. Further, the upper portions of the drying chamber 1 and the heat exchange chamber 5 are closed by plate-shaped shielding members 1a and 5a. In this way, the porous members 8, 8 and the partition member 1
0, 10, the warm air sent from the starting end openings 15, 15 is transferred to the obliquely installed partition member 1.
0, 10, it is blown out uniformly from the ventilation holes 9 of the porous members 8, 8 to the upper spaces A, B without any lateral variation, so that the seaweed m
is dried uniformly without any drying variation in the lateral direction. FIG. 5 is a partial front view shown for reference, and assuming that the partition member 10a is arranged horizontally as shown in the figure without being installed diagonally, the starting end opening 15
The closer it is, the more warm air will blow up into space A,
Only a small amount is blown up near the side plate 12 away from the starting end opening 15, so the seaweed m1 near the starting end opening 15 dries quickly, but the drying of the seaweed m2 away from here is delayed. If the partition member 10a is arranged horizontally in this way, the drying of the seaweed m will vary in the lateral direction of the drying chamber, and the seaweed m will not be dried uniformly.
0, 10, etc., the warm air is blown up into the spaces A and B more uniformly in the lateral direction of the drying chamber 1, and each piece of seaweed m is dried uniformly.

A reflux duct 16 is disposed on the other side of the drying chamber 1, and the upper and middle portions of the reflux duct 16 communicate with the spaces A and B through openings 25 and 25, respectively.
Reference numerals 18 and 18 are fans serving as blowers disposed within each return duct 16, and are rotated by a motor 19 disposed above the drying chamber 1. 20 is an air expansion chamber provided below the reflux duct 16, and the lower part of the reflux duct 16 communicates with the air expansion chamber 20. Reference numeral 21 denotes a heat exchanger disposed in the air expansion chamber 20, in which the air that has removed the moisture from the seaweed m flows down the reflux duct 16 as exhaust gas by the fans 18, 18, and is returned to the inside of the air expansion chamber 20. However, as soon as it enters the air expansion chamber 20, it undergoes adiabatic expansion, touches the heat exchanger 21, and the moisture in the exhaust gas turns into water droplets, and the water droplets 22 fall into the drainage channel 23 below and flow out. The air expansion chamber 20 communicates with an air flow passage 13 formed in the lower part of the drying chamber 1, and the exhaust gas from which moisture has been removed flows through the air flow passage 13 into the heat exchange chamber 5 again. . 24 is an exhaust port established on the outer wall of the air expansion chamber 20;
A portion of the exhaust gas is discharged to the outside world through the exhaust port 24. Reference numeral 26 denotes a damper for adjusting air volume, which is rotatably disposed at each of the ports 7, 15, and 15.
This seaweed drying device has the above-mentioned configuration, and the seaweed m conveyed in the drying chamber 1 is dried by removing moisture from the warm air sent from the heat exchange chamber 5, and the air contains a large amount of moisture. The moisture flows down the reflux duct 16 as exhaust gas, undergoes adiabatic expansion in the air expansion chamber 20, touches the heat exchanger 21, and is removed as water droplets. The air from which moisture has been removed has sufficient residual heat and enters the heat exchange chamber 5 through the air flow path 13, where it is heated again to a predetermined temperature and sent to the drying chamber 1. If the heated air is circulated and used repeatedly in the heat exchange chamber 5 in this way, and the moisture in the exhaust gas is removed in the form of droplets during the process, the residual heat of the exhaust gas can be used more effectively for secondary use, increasing thermal efficiency. can be significantly improved. Furthermore, if the upper part of the drying chamber 1 is not opened like in a conventional drying chamber, but is closed with a shielding member 1a, and the inside of the drying chamber 1 has a substantially sealed structure, the fan 18,
Since the drying chamber 1 is brought into a reduced pressure state by the blowing action of 18, the drying effect of the seaweed is further improved, and the dried seaweed has a good finish and can be produced with good quality. Furthermore, if the drying chamber 1 has a substantially sealed structure like this, the humidity and temperature of the drying chamber 1 can be controlled more accurately, and the exhaust gas with considerable residual heat can be removed from the top of the drying chamber at any time, unlike in conventional drying chambers. Moreover, since it is not wasted and is not emitted, heat loss can be further reduced and thermal efficiency can be greatly improved.

FIG. 3 shows another embodiment of the present invention, in which 30 is a plate-shaped porous member in which a large number of ventilation holes 31 are formed, and 32 is a partition member provided diagonally below the porous member 30. , both members 30 and 32 are the side plates 3
3 and 33 are integrated to form a substantially box-shaped balloon unit 34. In this way, the porous member 30 and the partition member 32 are made into a unit, and as shown in FIG. However, the holder 3 to which the seaweed cage 4 is attached may be conveyed in the direction of the arrow. By forming both members 30 and 32 into a unit in this way, assembly of the device becomes easier, and the starting end opening 35 of the unit 34 can face the damper 26 in the same manner as the starting end opening 15 of the first embodiment. This makes it possible to control the air volume more accurately.

The present invention can be modified in various ways other than the above-mentioned embodiments. For example, the upper part of the drying chamber may be open and the exhaust gas may be released from the upper part, or the endless chain 2 may be arranged in two stages, upper and lower. The present invention can also be applied to a type of laver drying apparatus in which the laver cage 4 is not attached to the holder 3 and is conveyed as is by an endless chain.

(Effects of the Invention) As explained above, according to the present invention, the warm air generated in the heat exchange chamber 5 can be blown up from the porous member 8 more uniformly without lateral variations, so that the warm air can be blown up into the conveyance path 2. Each piece of seaweed m transported along the line can be dried uniformly without lateral variations.
