Description

[Detailed Description of the Invention] The present invention relates to a dryer that is used in conjunction with drying at low temperature in broad daylight for bare-dried products, boiled-dried products, salt-dried products, etc., and high-temperature drying for coloring roast-dried products.

When drying fish, it is necessary to balance surface evaporation and internal diffusion.

In other words, since the flesh of the fish remains in a colloidal state, its internal diffusion is slow; therefore, if rapid drying is carried out, only surface evaporation (5kineffect) will occur, causing the surface to dry out too much, and evaporation from the surface will increase. Become slow.

When drying fish outdoors, drying in the shade slows down the drying rate, but surface evaporation and internal diffusion are balanced; however, when drying in the sun, only surface evaporation advances and internal diffusion slows down.

Here, it is deposited at night to stop surface evaporation, and only internal diffusion is performed to eliminate the density difference, to obtain uniform moisture on the surface and inside, and to repeat the process of drying again.In this way, only internal diffusion is performed. This process is called lid steaming, and allows you to obtain high-quality dried products.

In addition, if 5kineffect occurs during drying, internal diffusion of the fish body will be hindered, resulting in inferior products with a significant moisture difference between the surface and the inside, which may cause the fish to rot from the inside. According to the present invention, heating machines are installed before and after the drying chamber. A wood-burning furnace is installed next to the drying chamber, and by switching the direction of hot air to room A or room B at regular intervals, hot air is evenly supplied to all the carts stored in the drying room, and the temperature before and after the long drying room is maintained. It is possible to reduce the difference, use a wood-burning furnace and a heater together or use them alone, and furthermore, it is possible to adjust the air temperature by drawing in outside air.

i.e. high temperatures in wood-burning furnaces or heating-like applications;
Even in low-temperature drying, the temperature at the front and back of the drying chamber is averaged, and the temperature is alternately changed between high and low for lid steaming, so the internal diffusion of fish moisture and surface evaporation are moderately balanced without moving the trolley. You can make them do it.

Furthermore, by drawing in outside air, the temperature of the air blown into the drying chamber can be adjusted, so dry products such as bare-dried products, boiled-dried products, salt-dried products, etc. that are dried at relatively low temperatures can also be dried at relatively high temperatures. It is a drying device that can be used for both day-to-day and colored finishes, and can also produce dry products with a colored finish, such as roasted products.
Fish for boiled and soot-dried products and fish for roast-dried products have different fishing seasons, but this device can be used throughout the year.
Moreover, the present invention can be efficiently dried without requiring any human power.The present invention will be explained with reference to examples.

In Fig. 1, Fig. 2, and Fig. 3, the wind tunnel type drying chamber 1
The drying chamber 1 is divided in parallel into two partitions A and B in the middle in the longitudinal direction, and a hot air switching chamber 2 and a heat exchange chamber 3 are connected to one end of the drying chamber 1. A heat exchanger 6 heated by an arbitrary heating device 5 such as a burner is installed adjacent to the side, and a chimney 7 for discharging the exhaust air from the heating device 5 is installed.

The hot air switching chamber 2 is equipped with a hot air switching device 8 that switches the hot air sent from the heat exchanger 6 to room A or room B at regular intervals.

A dust collector 9 for removing sparks from the hot air from the wood burning furnace 10 is connected to the intake side of the Shirotsukunan 4, and an outside air suction damper 17 is installed for making it possible to take in outside air.

The dust collector 9 is connected to the wood-burning furnace 10 by a duct 11, and one end is connected to a bag duct 15 connected to the exhaust tower 16 of the drying chamber 1, and the duct 110 is connected to both ends of the bag duct 15. damper 12°13.1
4 respectively.

At the other end of the drying chamber 1, a rear switching chamber 1.8 is provided which communicates with both chambers A and B, and an appropriate reheater 19 is installed inside.

Therefore, the Shirotsukun Anne 4 can take in hot air from the wood-burning furnace 10 as well as outside air, and the exhaust gas is sent to the heat exchange chamber 3.
In the heat exchange room 3, the hot air can be heated by the heater 5.The hot air coming out of the heat exchange room 3 is made to flow into the A room or the B room depending on the operating position of the hot air switching device 8. The air is reheated in the chamber 18, passes through the B chamber or the A chamber, and is discharged to the outside from the exhaust tower 16 via the upper exhaust switching plate 20, which opens and closes in response to switching of the hot air switching device 8.

Further, depending on the type of fish to be dried, the exhaust gas can also be made to flow into the bag duct 14 leading to the dust collector 9 by the bag switching plate 21 in order to reuse waste heat, waste water, and exhaust smoke.

That is, when the hot air switching device 8 is in the E-port position, the hot air enters the B chamber, passes through the rear switching chamber 18 at the other end, enters the A chamber, exits the A chamber, is discharged from the exhaust tower 16, and is transferred to the hot air switching device. device 8
When the flow is Iha as shown by the dotted line, the flow becomes the opposite flow and is discharged from the exhaust tower 16.

In this case, the exhaust air switching device 204 is switched in conjunction with the operation of the hot air switching device 8, so that the hot air always passes through the A room and the B room before reaching the exhaust tower 16.

In the drying room 1, carts 23 carrying steamer baskets 22 for drying fish at intervals are arranged in series, and when hot air is sent, the hot air passes laterally through the gaps between the steamer baskets 22.

Since the present invention is constructed in this manner, as shown in FIG. 4, when hot air enters from room B, the temperature in the B1 part is high, but the temperature in the B2 part decreases, and after being heated by the reheating machine 19, It enters the A2 section, but the temperature becomes lower in the A1 section.

Next, if you switch and introduce hot air from room A, this will be reversed, and
Part 1 has a high temperature, part A2 has a low temperature, and after being reheated, part B2 has a high temperature and part B1 has a low temperature.

In other words, by switching the direction of the hot air, the temperature is alternately high and low in each section, making it possible to perform effective lid evaporation even when drying fish, and without having to move the trolley like in conventional fish dryers. The temperatures at the front and rear positions are harmonious, making it possible to produce high-quality dried products.

Furthermore, since the hot air sent into the drying chamber 1 is provided with a wood combustion furnace 10 and a heating machine 5, in the case of roasting and other processes that require high-temperature hot air, the hot air and smoke generated in the wood burning furnace 10 can be used. It is sent to the drying chamber 1 by a cooling fan 4, and when the temperature is low, the combustion state of the heater 5 is changed and the state of the heat exchanger 6 is changed to maintain a constant temperature, and then it can be sent to the drying room 1.

In addition, in cases such as drying, boiling, and soot drying that require low-temperature hot air, or when the temperature of the hot air from the wood-burning furnace 10 is high, the outside air is introduced from the outside air suction damper 17 using the sirotsuku fan 4 to lower the hot air temperature. It can be lowered and sent to the drying chamber 1 as heated air at a constant temperature.

Therefore, by constantly supplying heated air at constant high and low temperatures to the drying chamber 1, fish can be effectively dried, and both colored and day-dish finishes can be achieved.
