Description

[Detailed description of the invention] The present invention consists of a series of drying devices in which a blower is installed at one end of a wind tunnel type drying chamber, and an exhaust chamber and an exhaust tower for discharging waste hot air are placed at the other end. In a fish drying device in which two units are connected in parallel in opposite directions, a plurality of steam heat exchangers connected to steam piping are installed at intervals inside both drying chambers installed in parallel, and the Each of the exhaust chambers is connected to an adjacent blower via a mixing chamber, and the mixing chamber has a switching chamber and a branch air volume installed at the upper part of the side wall of the exhaust chamber to switch between the exhaust tower side and the mixing chamber side leading to the blower. Fish drying by steam heating, which has an inlet with a switching control door and a freely adjustable suction door for the adjustment of water temperature, and an outside air intake hole 19 on the top wall that can be opened and closed freely. It is a device.

Conventionally, there is a fish drying device in which two drying devices are installed side by side and connected and interlocked, but all of them are high-temperature hot air type drying devices that utilize a heating device such as a burner or heating furnace at one or both ends. The temperature distribution inside the drying chamber becomes uneven, and the hot air heated by these heating devices is sent into the drying chamber by a blower, which causes frequent failures of the blower.In addition, the capacity increases as the hot air that has expanded thermally is sent in all at once, causing the blower to fail. There was a drawback that I had to increase my ability. In addition, since exhaust hot air is discharged to the outside, intake for recirculation, and outside air is introduced by simply switching and opening/closing, the adjustment and mixing of the amount of intake of exhaust hot air and outside air becomes unstable, which deteriorates the quality of the product. A lot of things happened.

The purpose of this invention is to dry a large amount of fish using a heat exchanger using heated steam. The temperature distribution throughout the drying chamber is made uniform, improving drying efficiency, and it is possible to prevent product quality from deteriorating due to overheating or underheating, which is the case with conventional centralized heating methods. In addition, the exhaust chambers at both ends are connected to the adjacent exhaust fan through the mixing chamber and to the exhaust tower, so the damp exhaust hot air can be removed by adjusting the opening and closing of the switching control door installed at the intake port of the mixing chamber. can be inhaled or switched proportionally to the exhaust tower and mixing chamber,
Further, the mixing chamber can increase the inflow of exhaust hot air by adjusting the opening and closing of the suction door, and on the other hand, can draw in and mix dry outside air as appropriate by adjusting the opening and closing of the outside air introduction door. Therefore, it is possible to optimally mix and adjust the amount of intake and discharge of moist exhaust hot air and the amount of introduced dry outside air depending on the initial drying and final drying during the drying process.

The present invention will be explained below with reference to Examples. In FIGS. 1 and 2, a blower 2 driven by a motor 3 is connected to one end of a wind tunnel type drying chamber 1, and an exhaust chamber 4 at the other end for discharging the hot air that has passed through the drying chamber 1. A series of drying apparatuses each having a ventilation tower 5 and an exhaust tower 5 are connected in parallel in opposite directions. One of the drying chambers 1 is provided with a plurality of entrance/exit doors 8 on the side for putting in and taking out the steamers 6, and the steamers 6 are inserted through one of the drying chambers 1 at a position opposite to the entrance/exit door 8 on the side of the other drying chamber 1. An indoor door 9 for entry and exit is provided. Both drying chambers 1 house a cart 7 stacked with steamers 6 filled with fish.

In such a drying device, the present invention has the following features:
A plurality of steam heat exchangers 10 are arranged at intervals inside both drying chambers 1 installed in parallel, and a drain pipe 13 is installed.
Attached. The steam heat exchangers 10 are each connected to steam piping 11 connected to a boiler (not shown). The exhaust chambers 4 at both ends are connected to the adjacent blower 2 through a mixing chamber 12 for mixing exhaust hot air and outside air, and are connected to an exhaust tower 5.
It is configured such that the exhaust hot air discharged from the exhaust port 14 of the exhaust chamber 4 flows into the adjacent blower 2 side or the exhaust tower 5 side. As shown in FIGS. 3 and 4, in the mixing chamber 12, the lower part of the side wall of the exhaust chamber 4 is closed, and the exhaust hot air is sucked into the upper part, so that the hot air flows evenly into the drying chamber 1. An inlet 15 is provided to switch the exhaust hot air flowing into the exhaust tower 5 and the exhaust hot air flowing into the mixing chamber 12 through the inlet 15.
In addition, a switching control door 16 for adjusting the amount of divided air flow and an intake door 17 that can be opened and closed are arranged vertically in parallel, and an outside air intake hole 18 is bored in the upper wall, and an outside air introduction door 19 that can be opened and closed can be adjusted. will be established.

In the present invention configured as described above, the heat source is the steam heat exchanger 10, and since a plurality of heat exchangers 10 are installed at intervals, overheating does not occur unlike heat sources such as burners or heating furnaces. In addition, since the entire drying chamber is heated almost uniformly through segmental heating, the product can be finished evenly and uniformly.
In particular, the steam heat exchanger 10 has the advantage that the number of installations can be easily increased just by constructing piping.

In addition, the exhaust hot air from one of the drying chambers 1 enters the exhaust chamber 4 and flows into the mixing chamber 12 or the exhaust tower 5. At this time, the switching adjustment door 16 of the mixing chamber 12 is adjusted to open or close the mixing chamber 12. The amount of air flowing into the exhaust tower 5 can be changed as appropriate, and furthermore, it can be switched to flow into only either the mixing chamber 12 or the exhaust tower 5 by fully opening or closing. Further, by adjusting the opening and closing of the suction door 17, the amount of exhaust hot air sucked into the mixing chamber 12 can be further adjusted. The mixing chamber 12 optimally mixes the humid exhaust hot air that is sucked in with dry, low-temperature outside air that is sucked in by adjusting the opening and closing of the outside air introduction door 19 on the top wall. It is sent to the drying chamber 1 and circulated. A plurality of steam heat exchangers 1 are installed in both drying chambers 1.
Since the drying chamber 1 is heated in multiple stages, the temperature and humidity distribution inside the drying chamber 1 is uniformized.
Dry the fish inside in the best possible condition.

As mentioned above, the present invention is suitable for drying a large amount of fish because the temperature distribution inside the drying chamber is almost uniform, and
The exhaust hot air and outside air are mixed at the time of the drying process and sent into the drying room for circulation, so it is not only suitable for mass production, but also improves product quality and saves energy. It is effective.
