Description

Dryer with moisture removal and air circulation{Dryer For Agricultural and Marine Products}

The present invention relates to a dryer having moisture removal and air circulation, and more particularly, sterilization and disinfection effects for drying objects are achieved through circulation of air circulated inside the dryer while irradiating infrared light in the dryer. , It relates to a dryer having moisture removal and air circulation, which can expect an improved drying effect.

Among the objects to be dried, most agricultural and marine products that need to be dried are naturally dried in a way that breathes natural air with natural light.

However, if the timing of the sale of agricultural and fishery products to wholesalers changes rapidly according to the market conditions, such a natural drying method is causing the inconvenience of not meeting the delivery date of the sale of wholesalers.

Since natural drying is not literally artificial drying, the drying period cannot be artificially shortened. In particular, crops such as agricultural and marine products are inevitably sensitive to the drying period.

In addition, natural drying requires a daily check of the weather conditions, and in non-today days, the hassle of collecting agricultural and marine products occurs.

As such, natural drying of agricultural and marine products cannot artificially shorten the drying period, the weather conditions are checked daily, and natural drying is difficult due to troublesome problems such as recovery of agricultural and marine products during gusts and rainy seasons.

Therefore, as an alternative to natural drying, artificial drying dryers have been developed or released, and as a conventional patent, Korean Patent No. 10-0635474 is exemplified.

The conventional registered patent is a circulation type hot air dryer that artificially drys the object to be dried using hot air. However, such a circulation type hot air dryer is not particularly suitable for drying agricultural and marine products, which are foods that place importance on safety, due to the limitation that it cannot be irradiated to the deep inside of the object to be dried because it simply uses hot air to dry the object to be dried.

In addition, most of the existing dryers dry the objects to be dried using the circulation type hot air method, but they do not properly remove the moisture contained in the hot air, and the drying factors related to the flow rate, flow rate, temperature, etc. of the hot air circulating inside the dryer are not properly removed. Due to the inability to constantly monitor and cope with the situation, it is difficult to expect a more substantially improved drying effect, although the objects to be dried are dried.

In the present invention, the accompanying drawings are shown exaggerated for clarity and convenience of description, and the embodiments to be described later do not limit the scope of the present invention, but are based on exemplary matters of the constituent elements presented in the claims of the present invention. However, it should be interpreted based on the technical idea throughout the specification taking into account that it is modified in various other forms.

Hereinafter, a dryer having moisture removal and air circulation according to a preferred embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

The dryer 10 having moisture removal and air circulation according to the present invention is a dryer 10 having a box-shaped appearance as shown in FIG. 1, and one of them is configured with an opening and closing door 11 for opening the interior thereof. In the upper one side of the dryer 10, a ventilation port 12 is configured to remove moisture with the inflow of air, and at the upper center of the dryer 10, a motor 13 as a power source for rotating the drying table 20, which will be described later, is provided. ) Is composed.

The ventilation port 12 is a place to evaporate and remove moisture generated by a temperature difference between the inside and outside of the dryer 10 while allowing outside air to flow into the inside of the dryer 10 by contact with hot air.

The exterior of the box-type box dryer 10 includes an opening and closing door 11 and a ventilation hole 12 as described above, and the dryer 10 has a drying rack 20 and a dryer installed in the central space as shown in FIG. 3. It is composed of a heat insulating plate 50, an air flow inlet plate 40, and an air flow exhaust plate 40' which are sequentially sealed and installed along the inner wall of 10). Of course, the heat insulating plate 50 may be installed on the inner wall of the opening and closing door 11.

The drying rack 20 is rotated by being coupled with a rotation shaft of a motor in the indoor center of the dryer 10, as shown in FIG. 3, but also to the rotation mounting structure 21 having a function of receiving and mounting the trays 22, and the rotation mounting structure. It is accommodated and mounted in an inclined form, but may be composed of a plurality of trays 22 mounted with a certain height difference between each other. In particular, the rotation mounting structure 21 maintains a predetermined height difference interval over its vertical length for receiving and mounting the trays 22, and a plurality of support dies 21a extending in one direction in an inclined manner. It may be composed of, and the trays 22 may be formed of a structure of a mesh (22a) capable of raising the object to be dried while having a smooth ventilation structure.

The inner wall of the dryer 10 is a box-shaped box type, and consists of six walls of top, bottom, left, right, front, and rear. Although not specifically shown in the drawing, the heat insulating plate 50 along the inside of the six walls. ) Is also composed of 6 walls, and is composed of an air flow inlet plate 40 and an air flow exhaust plate 40' in the left and right directions on the inside of the 6 walls of the heat insulation plate 50, and in the up, down, front, and rear directions It is sealed with a partition (not shown), and reflectors not shown in the drawing may be formed inside the airflow inlet plate 40 and the airflow exhaust plate 40' and the partition, and the reflector is also composed of a six-wall structure. Can be.

The reflector may be separately provided inside the air flow inlet plate 40 and the air flow exhaust plate 40 ′, but in some cases, the reflector may be formed as an outer surface of the air flow inlet plate 40 and the air flow exhaust plate 40 ′. May be. It is preferable to use a material composed of a composite material of titanium dioxide and mica as the reflector, because the reflectance of infrared light irradiated from the infrared lamp 45 is high. Of course, in the reflector, along with a through space through which infrared light can be emitted from the infrared lamp 45, the inlet holes 43 of the airflow inlet plate 40 and the exhaust holes 43' of the airflow exhaust plate 40' Through holes for smooth air flow from the can be formed.

The composite material of titanium dioxide and mica is synthesized as a composite material of titanium dioxide and mica by hydrolysis and condensation reaction of titanium isopropoxide in aqueous acetic acid solution.

Titanium dioxide in amorphous phase formed on the mica surface by heat treatment (600∼1000 ℃, 1∼3 h) of a composite material of titanium dioxide and mica is converted to a crystalline rutile phase through an athase phase. And the crystal size is controlled by the heat treatment conditions.

Through FE-SEM analysis, ED-XRF analysis, and XRPD analysis, the physicochemical properties of titanium dioxide and mica composite materials can be identified. The solar reflectance in the infrared range (780-2,500 nm) was 88.6%, slightly higher than 86.6% of pure fired mica. Therefore, the titanium dioxide and mica hybrid composite material can be used as a reflective material for infrared light exhibiting high light reflectance. Of course, not only the above-described composite material, but also any one of aluminum foil or silver foil may be used depending on the type of the object to be dried.

In this way, since the reflector has a mirror made of SUS (Steel Use Stainless) material for reflection of infrared light, even through the reflected light of infrared light, the object to be built (e.g., agricultural and marine products) placed on the net 22a of the trays 22 ) Can be dried to improve the drying effect.

External air introduced from the ventilation port 12 is forcibly introduced in the direction of the intake fan 42 configured inside the dryer 10 as a position opposite the ventilation port as shown in FIG. 3. This external air flows through the intake fan 42. Through the inlet hole 43 of the air flow inlet plate 40, it passes through the trays 22 of the drying table 20, and the objects to be dried are dried on the trays 22a of the trays 22.

Of course, in this process, the light irradiated from the infrared lamp 45 installed in the recessed space 44 of the air flow inlet plate 40 is irradiated in the direction of the area of the object to be dried placed on the trays 22a of the trays 22. The light irradiated from the infrared lamp 45 installed in the recessed space 44 of the airflow exhaust plate 40' is also irradiated in the direction of the area of the object to be built placed on the trays 22a of the trays 22 And can be permeable.

The heat insulating plate 50 is provided for a heat blocking function to maintain the internal indoor temperature of the dryer 10, and the air flow inlet plate 40 is formed through a ventilation opening 12 formed on the exterior of the dryer 10. It is provided to forcibly introduce external air into the interior space of the dryer 10.

In this way, the heat insulating plate 50 and the air flow inlet plate 40 are combined in a manner in which the air flow inlet plate 40 is added to one surface of the heat insulator plate 50 as shown in FIGS. 2 and 3, and the air flow inlet plate ( 40) is, for example, a grille 41 of a lattice structure configured at the top as shown in FIG. 2, a plurality of intake fans 42 fixedly coupled to the grill 41, and a plurality of inflows passing through to the opposite side where the heat insulating plate is padded. It consists of a hole 43 and a recessed space 44 recessed inward along the center of the surface on which the inlet holes are formed, and an infrared lamp 45 vertically inserted into the recessed space.

In particular, the inlet holes 43 are formed evenly distributed over the entire area other than the recessed space 44 formed as the central portion of the air flow inlet plate 40, and these inlet holes 43 are particularly the air flow inlet The plate 40 is characterized by having a structural arrangement pattern in which the diameter gradually decreases from the top to the bottom.

That is, the diameter of the inlet holes 43 is reduced from the top to the bottom of the air flow inlet plate 40 from the inlet holes 43 located at the bottom of the air flow inlet plate 40 This is to ensure that the amount of air coming into the interior of the dryer 20 and the amount of air coming out of the inlet holes 43 located at the top of the air flow inlet plate 40 are equal to each other.

This, in turn, has the effect of uniform drying of the object to be dried, which is placed on the trays 22a of the trays 22 installed on the individual support dies 21a of the rotating mounting structure 21. If the diameter of the inlet hole 43 positioned above the air flow inlet plate 40 is smaller than the inlet hole 43 positioned below the air flow inlet plate 40, the lower portion of the air flow inlet plate 40 Since the amount of air from the dryer 20 to the interior of the dryer 20 is relatively large compared to the upper portion of the air flow inlet plate 40, the amount of air cannot be uniform, which means that the drying of the object to be dried cannot be uniform.

Accordingly, in order to solve the problem of uneven drying of the object to be dried, the diameters of the inlet holes 43 have an arrangement pattern of a shaft diameter that decreases from the top to the bottom of the air flow inlet plate 40.

Meanwhile, a plurality of exhaust holes 43' are formed in the airflow exhaust plate 40' located opposite the airflow inlet plate 40, and these exhaust holes 43' are the airflow exhaust plates 40' ) Is not formed in the upper portion of the airflow exhaust plate 40 ′, but is formed only in the lower portion of the airflow exhaust plate 40 ′. That is, the exhaust holes 43 ′ are formed only in the lower portion of the airflow exhaust plate 40 ′, which induces the air introduced into the interior of the dryer 10 to move to the lower corner of the interior of the dryer 10 It is to exhaust it to the outside while enhancing the drying effect.

In addition, the formation of the exhaust holes 43 ′ under the airflow exhaust plate 40 ′ is also intended to maintain a constant temperature difference between the upper, middle, and lower temperatures that appear inside the dryer. That is, since the exhaust holes 43 ′ are formed under the airflow exhaust plate 40 ′, air having a temperature difference is mixed with each other in the process of moving the air toward the lower part to maintain a uniform temperature. .

The airflow exhaust plate 40 ′ is further formed along the center of the surface on which the exhaust holes 43 ′ are formed along with the configuration of the exhaust holes 43 ′ and perpendicularly to the recessed space 44 and the recessed space. It may be composed of an infrared lamp 45 installed in a plugged state, and the depression space 44 and the infrared lamp 45 correspond identically to the depression space and the infrared lamp configured in the air flow inlet plate 40, and the symbol Also may be a configuration that is indicated in the same manner.

Here, the grill 41 may be configured with a plurality of empty passage structures as a way to promote smooth inflow of external air from the ventilation opening 12 configured on one side of the upper end of the box-shaped box, and an intake fan fixedly installed on the grill ( 42) are a function for forcibly introducing external air from the ventilation port 12 to the inside of the grill 41.

The outside air that has passed through the grill 41 is a drying rack installed in the center of the inside of the box-shaped box through the inlet holes 43 through a number of holes 43 on one side of the air flow inlet plate 40, that is, on the opposite side of the side covered with the heat insulation plate. It moves toward the tray (not shown) caught in (20).

At this time, since the external air is heated by infrared light and supplied to a tray (not shown) caught in the drying table 20 with hot air, the drying efficiency of the object to be dried (agricultural and marine products) can be further improved.

The infrared lamp 45 vertically inserted in the recessed space 44 is the same as the air moving toward the trays 22a formed in the trays 22 of the drying table 20 in the direction of the beams 22a. Light is irradiated to dry the object to be dried on each of the nets (22a).

Of course, as the rotation mounting structure 21 is coupled to the rotation shaft of the motor 13 and rotated through the power of the motor 13, the rotation mounting structure 21 is mounted on the individual supporting dies 21 of the rotation mounting structure 21 The fixed trays 22 are also rotated simultaneously, so that the object to be dried on each tray 22 receives infrared light irradiated from the infrared lamp 45 and is in contact with the heated air to be evenly dried. .

In particular, the trays 22 have a round circular shape and are mounted on and fixed to the individual support dies 21a of the rotating mounting structure 21, so that the trays 22 are mounted on the trays 22a of the trays 22. In the process of drying the objects to be dried, as they come into contact with the heated air in a completely open state without any disturbing factors that may hinder drying, as the drying process is accelerated, the drying time of the objects to be dried can be expected to be shortened.

In addition, the trays 22 are mounted and fixed in an inclined structure to the individual support dies 21a of the rotating mounting structure 21, and the inclined installation structure of the trays 22 is Since it corresponds to a structure that can secure more of the irradiation area of the infrared light and the exposed area of the object to be dried exposed to the heated air, the drying process of the object to be dried is inevitably promoted, and the inclination of the trays 22 is It is preferable to be installed in the inclination range of 10° to 30°.

In other words, if the trays 22 are mounted in a horizontal structure on the individual support dies 21a of the rotating mounting structure 21, not only the irradiation area irradiated from light but also the contact area contacting air is inclined. Since the structure is relatively less secured, the drying process of the object to be dried is also inevitably delayed.

The reason why the trays 22 are installed in the above inclined range is due to the drying efficiency of the object to be dried on each of the trays 22a, and when the trays 22 are installed below 10°, the trays 22 are almost horizontally related. Since the irradiation area of infrared rays is relatively small, the drying efficiency of the object to be dried is inevitably lowered, and when the trays 22 are installed in excess of 30°, the inclination of the trays 22 is rapid, so that each of the trays 22a ), it is preferable that the inclination angles of the trays 22 fall within the inclination range described above.

In particular, the reason why the inclination of 40° exceeds 30° but is close to 30° does not belong to the inclination range of the present invention is because the factor in which the drying table 20 is rotated cannot be overlooked. In other words, even if the drying rack 20 is installed at an inclination angle of 40°, the correlation between the centrifugal force acting on the objects to be dried on the racks 22a of the trays 22 during the rotation of the drying rack 20 and the inclination angle Falling of the object to be dried can be easily caused, and for this reason, only up to an inclination angle of 30° is placed in the scope of the present invention.

In addition, the inclination range in the present invention is also because it facilitates circulation and flow of the hot air introduced into the interior of the dryer 10. When the drying rack 20 is installed with an inclination of less than 10°, the drying rack Even in the rotation process of (20), the drying rack (20) is close to the horizontal angle, so the circulation flow of hot air cannot be promoted, and even if it is installed at an inclination of more than 30°, the circulation flow of hot air is more biased to the vertical angle. It becomes impossible to promote.

That is, when the drying rack 20 is installed in an inclination range of 10° or more to 30° or less, it can act as a factor that promotes the flow of hot air circulation, such as a fan effect, according to the occurrence of the inclination angle of the drying rack 20. Because.

On the other hand, the inside of the dryer 10 may be provided with flow controllers (C), a temperature sensor (T), and a detector (D) shown in Figure 5, the outside of the dryer 10 shown in Figure 5 The central processing unit P may be installed anywhere on the exterior of the dryer 10 as shown in FIG. 1. Of course, these flow controllers (C), temperature sensor (T), and detector (D) are all connected to each other through a wire circuit so as to exchange electrical signals with the central processing unit (P).

The flow controller (C) is not shown in the drawing, but is provided in a structure installed in the portion of the exhaust hole (43') formed under the airflow exhaust plate (40') to prevent hot air exhausted from the exhaust holes (43'). It can be controlled by adjusting the displacement. The flow controller (C) may be combined with components of an inlet port for introducing the hot air fluid, an outlet port for outflowing the hot air fluid, a sensor for detecting the hot air flow rate, and a valve for controlling the hot air flow rate. have.

As shown in FIG. 4, the temperature sensor T is a structure installed at a portion where air is circulated in the lower portion of the dryer 10, and may be provided at a lower portion of the rotating mounting structure 21 of the drying table 20, The temperature of the hot air introduced into the drying table 20 may be checked in real time. The detector (D) is an inner lower part of the rotating mounting structure 21 of the drying table 20 and may be provided in a structure installed in the lower part of the rotating mounting structure 21, and the flow rate of hot air for drying the drying object , It is possible to comprehensively check the content of moisture remaining in the hot air, the temperature of the hot air, and the amount of hot air, and transmit the detected data to the central processing unit P. Of course, the above temperature sensor (T) and detector (D) do not need to be installed in a manner limited to a specific portion of the dryer 10 including the drying table 20 if, for example, a region in which sensing is quickly sensitized.

The central processing unit (P) is provided in a structure installed on the exterior of the dryer (10) as shown in Fig. 1, and in a state that receives the detection data transmitted from the detector (D), the detection data is already dry optimal data required for drying. By comparing and analyzing the result data stored as a result data, the result of identifying whether the detection data has a higher drying effect on the object to be dried than the result data can be provided.

The result data is the drying optimization data, which has been secured and verified through simulations of dozens to hundreds of times and is obtained through learning of artificial intelligence, and the drying optimization data is operation data that can be changed according to the setting operation. However, in terms of the actual detection data for drying the object to be dried inside the dryer 10, the drying optimization data may be a reference.

In particular, the drainage port 41 ′ formed at the bottom of the dryer 10 shown in FIGS. 3 and 4 as the other lower corner of the inside of the dryer 10 absorbs the hot air introduced into the drying rack 20. It is naturally exhausted to the bottom of the dryer 10.

The intake fan 43 may be rotated through motor power, and the number of rotations of the intake fan 43 may be controlled and adjusted by the central processing unit P. Moreover, the flow controller C is also controlled by the central processing unit P to adjust the valve opening of the flow controller C.

Air may partially pass through the moisture drainage port 41 ′ formed on the inner bottom of the dryer 10, and some may pass through the filter F shown in FIGS. 3 and 4, such that the filter ( F) may be configured in such a way that it is installed at a location of a convection starting point of air that can be re-introduced into the inside of the dryer 10 by moving to the other lower corner of the inside of the dryer 10 and then rising again.

Therefore, the air that is going to rise again after heading to the lower inner corner of the dryer 10 passes through the filter F and rises to the top of the dryer 10. In this process, the air passes through the filter F. Moisture can be removed during the fermentation process.

That is, since the air is dried in a way that takes away moisture contained in the objects to be dried on the trays 22 in the process of passing through the drying rack 20, the filter F ), the moisture can be re-introduced into the inside of the dryer 10 with the moisture removed.

The filter (F) is preferably a filter for separating and removing moisture contained in a fluid such as air, and it is preferable that an angle installed at the inner bottom of the dryer 10 is installed vertically close to 90°. .

Although not specified in the drawing, the filter has a multi-layered wave structure that effectively separates and removes the fluid and moisture of the hot air. For example, the filter has a structure in which two layers of 0.1 to 0.5 pie STS nets are waved into one group, During the drying process, the scattering of water droplets and moist moisture can be efficiently collected from the fluid of the hot air containing moisture, and it can be used semi-permanently with ease of cleaning.

The frame applied to the filter of the multi-layered wave structure is made of SUS or aluminum to prevent corrosion, and the filter of the multi-layered wave structure captures 95% of dust, for example, 10 um or more, especially viscous substances such as moisture. It is effective to collect and has a very low pressure loss, so it is suitable for use with fans for low-volume applications.

Collection efficiency refers to the degree to which the filter collects dust as a percentage (%), and the pressure loss (mmAq, Pa) is the pressure drop formed at the moment air passes through the filter, and the initial pressure loss means that the filter is not contaminated. It means the time, and the pressure loss at the end is the time when the resistance of the filter reaches the maximum value and means the cleaning time of the filter.

An experiment comparing the filter having the multi-layered wave structure and the existing filter is as follows.

When the diameter (Ø) of the drainage port 41' formed at the bottom of the inside of the dryer 10 is, for example, 150mm × 150mm or 200mm × 200mm, the existing filter A installed in the drainage port 41' , B and C are respectively installed at an inclination of 35 to 45°, whereas the filter in the present invention is installed at an inclination close to approximately 90° vertically from the drainage port 41'.

Filter type Filter (this invention) Filter A (existing) Filter B (existing) Filter C (Conventional) Filter installation angle (°) 90 35 to 45 34 to 45 34 to 45 Moisture collection efficiency (%) Gravimetric method 87.5 76.1 76.5 77.8 Process test 88.34 54.84 Pressure loss (mmAq) Gravimetric method 2.75 4.7 4.5 4.2 Process test 2.4 4.4

In this case, as shown in Table 1, the filter in the present invention increases the face velocity of the filter due to an increase in the moisture collection area of the filter relative to the space of the drainage port 41 ′ compared to the existing filters. It was found to increase the moisture collection efficiency by reducing it, and to lower the filtration pressure loss due to the decrease in wind speed.

Filter (this invention) Filter A (existing) Filter B (existing) Cleaning method Air injection (contains moisture: mixed injection of air and moisture) Water spray Water spray Washing direction Filter rear Filter rear Filter both sides Drying Nozzle atomizing No drying process spray Drying efficiency (%) 91 - 33.7

In addition, as shown in Table 2, it was found that the filter in the present invention has superior drying efficiency compared to existing filters.

On the other hand, since a spring plunger (not shown) is provided at the part of the motor 13, the drying object (eg, agricultural and marine products) is Upon completion of drying, the drying table 20 can be rotated by the manual operation of the spring plunger even if the location of the object to be dried is not at the position of the opening and closing door 11 of the dryer 10 according to the end of the driving of the motor 13. According to manual operation, the take-out direction of the trays 22 mounted on the individual support dies 21a of the rotating mounting structure 21 can be matched with the opening direction of the opening and closing door 11, so that the trays 22 By being easily taken out to the outside of (10), the object to be dried can also be easily collected.

On the other hand, the reflector is an infrared ray irradiated toward the object to be built on the screen 22a of the trays 22 mounted on the individual support dies 21a of the rotating mounting structure 21 at the outer circumference of the drying table 20 By performing the function of reflecting and returning the drying object, the drying process of the object to be dried can be further promoted, and the hygiene and safety of the object to be dried can be ensured by allowing the infrared rays to be transmitted evenly to the deeper part of the object to be dried. I can.

Here, safety refers to a state in which sterilization and sterilization are performed up to the deep inside of the object to be dried by infrared irradiation. The reflector may be formed of a mirror made of an SUS material or an aluminum foil material for reflection efficiency.

On the other hand, in the trays 22, there is a possibility that the object to be dried may be burned according to the increase in heat temperature due to heat conduction, so a heat detection sensor (not shown) capable of detecting the heat temperature is installed inside the dryer 10. It may be installed and provided, and such a heat sensor detects the heat temperature before reaching the combustion critical point of the object to be dried, and cuts off the current to the infrared lamp 45 according to the operation of the reed switch by the movement of the permanent magnet by the detection signal. It is possible to prevent the problem of burning the object.

That is, the permanent magnet is moved toward the reed switch by the sensing signal of the heat sensor, and at this time, the reed switch supplies current in a state in which the two magnetic reed pieces, which are sealed inside the glass tube, are closed to each other by spring elasticity. A, according to the approach of the permanent magnet, the two magnetic lead pieces are opened to each other and a contact is short-circuited, thereby blocking the current to the infrared lamp 45.

The configuration of the heat sensor, the permanent magnet, and the reed switch is not shown in the accompanying drawings, and it is noted that it can be installed at any specific location of the dryer 10.

In the following, the working relationship of the dryer for the embodiment of the present invention will be described later.

The opening and closing door 11 of the dryer 10 is opened, and the object to be dried is placed on the trays 22a of the trays 22 mounted on the individual support dies 21a of the rotary mounting structure 21. 11) Drive the dryer 10 in the closed state.

When the dryer 10 is driven, the drying rack 20 is rotated together in accordance with the axial rotation of the motor 13 inside the dryer 10, and the air flow inlet plate 40 during the rotational operation of the drying rack 20 And the infrared light through the infrared lamp 45 installed on the airflow exhaust plate 40' is transmitted in the direction of the trays 22 mounted on the individual supporting dies 21a of the rotating mounting structure 21, and The object to be dried is dried.

At this time, the infrared light can be irradiated and transmitted in the direction of the trays 22 while passing through the reflector located inside the airflow inlet plate 40 and the airflow exhaust plate 40'. Infrared light irradiated through a mirror made of SUS or aluminum foil formed as a part surface is reflected in the direction of the trays 22, and drying efficiency of the object to be dried can be improved.

On the other hand, external air may be forcibly introduced from the ventilation opening 12 configured on the upper side of the dryer 10, and this external air is through the intake fan 42 fixed to the upper grill 41 of the air flow inlet plate 40. As it flows in, it moves along the inside of the air flow inlet plate 40 and is supplied to move in the direction of the trays 22 through the inlet holes 43 of the air flow inlet plate 40.

At this time, the external air that has passed through the inlet holes 43 of the air flow inlet plate 40 moves in the direction of the trays 22 through the through holes of the reflector plate. In this process, the outside air is blown in the direction of the trays 22 according to the temperature increase due to the infrared light, so that the drying efficiency of the object to be dried can be further increased.

As shown in FIG. 3, the hot air comes out from the inlet holes 43 of the air flow inlet plates 40 and passes through the trays 22, and some of the hot air that has passed through the trays 22 is the air flow inlet plate ( While moving in the direction of the lower corner of the airflow exhaust plates 40' located opposite to 40), the exhaust may be exhausted through the drainage port 41' shown in FIGS. 3 and 4.

Of course, some of the air remaining in this process passes through the filtration filter F of FIG. 4 at the point when it is about to rise while being exhausted through the exhaust holes 43 ′ arranged under the airflow exhaust plate 40 ′. It rises to the top, and at this time, the moisture contained in the air can be filtered through the filtration filter (F).

Accordingly, the hot air from which moisture has been removed is combined with the external air forced in by the intake fans 42 located opposite the air in the process of rising upward of the dryer 10. It goes through a cycle of re-inflow into the interior.

That is, the hot air that has been exhausted through the exhaust holes 43 ′ and rises through the filtration filter F is mixed with the external air introduced through one corner of the ventilation port 12 provided at the upper one side of the dryer 10. As a result, the movement process of being forced back into the air flow inlet plate 40 by the intake fan 42 is repeated, and the air can circulate inside the dryer 10 according to the repeated movement of the air.

On the other hand, in the process of exhausting the hot air through the airflow exhaust plate 40' and rising, moisture may be generated around the ventilation opening 12 provided at the upper end of the dryer 10 due to the difference in temperature inside and outside the dryer 10 The moisture can be expected to be reduced in such a manner that the moisture is evaporated by frequent contact with the hot air rising along the interior of the airflow exhaust plate 40 ′.

In other words, this moisture removal has the characteristic of solving the moisture problem that often occurs around the ventilation or exhaust port of the existing dryer at once, and it is very easy to dry maintenance of the dryer, and it prevents corrosion of the dryer due to the moisture problem. It has the effect of not causing malfunction of the dryer.

On the other hand, the inside of the dryer 10 may be provided with flow controllers (C), a temperature sensor (T), and a detector (D) shown in Fig. 5, the outside of the dryer 10 shown in Fig. A central processing unit (P) may be provided, and these flow controllers (C), temperature sensors (T), and detectors (D) are all controlled and adjusted by exchanging electrical signals with the central processing unit (P). , It is possible to optimize the drying efficiency of the drying objects placed on the trays 22a of the trays 22 inside the dryer 10.

In a state in which external air is introduced into the dryer 10 and the air is raised to a certain level that can be dried by the irradiated light over a certain period of time, the flow controller C is applied to the air as shown in FIG. Humidity detection data that detects the amount of humidity contained is transmitted to the central processing unit (P), and the temperature sensor (T) transmits temperature sensing data that detects the temperature of the air to the central processing unit (P).

At this time, the central processing unit (P) analyzes the received humidity detection data and temperature detection data, and determines whether the drying can be completed by the drying time of the object even with the current humidity detection data and temperature detection data. When it is determined that the drying object cannot be dried until the drying time required by the current humidity detection data and temperature detection data, the central processing unit (P) transmits a control primary instruction signal to the flow rate controller (C). (C) can adjust the opening of the valve based on the control primary instruction signal.

If it is determined that drying of the object to be dried is completed by the time required for drying even with the current humidity detection data and temperature detection data, the central processing unit P does not control the flow control unit C, and the flow control unit is not operated. Here, the data dealing with the drying of the object to be dried until the required drying time is data that is the result of an experiment through simulations for tens to hundreds of times, and is optimal drying data. This drying optimization data is stored in the central processing unit P, and may be operation data that can be changed according to a setting operation.

In addition, the drying optimal data is data belonging to the class A with the best drying rate per hour, for example, the drying rate per hour is A grade (dry rate 100-81%), B grade (dry rate 80-61%), C grade ( Drying rate 60 to 41%), D grade (drying rate 40 to 21%), and E grade (drying rate 20 to 1%). The drying optimization data is data consisting of values in which the air flow rate, air flow rate, and air temperature value corresponding to the drying requirements are specified so that the drying rate for a specific object per hour in a specific space area belongs to Class A. to be.

Therefore, the actual detection data to be detected by the detector (D) to be described later can be compared and analyzed with the drying optimization data, and the drying optimization data is the actual detection data side of drying the object to be dried inside the dryer 10. This is the standard data when viewed from.

When the opening of the valve to the flow controller (C) is adjusted, the object to be dried is dried through the air supplied to the inside of the dryer (10) while the amount of air exhausted to the exhaust holes (43') is adjusted. The drying progress state is continued, and at this time, the detector D detects comprehensive data whether drying can be completed by the drying time required for the object to be dried.

That is, the detector D detects comprehensive data as a method to determine whether drying of the object to be dried can be completed by the time required to dry. Such comprehensive data can be referred to as detection data. The detection data is detection data reflecting all of the air supply amount, air flow rate, air temperature, and humidity contained in the air as optimal drying requirements for the drying object.

The detection data detected by the detector D may be transmitted to the central processing unit P, and the central processing unit P performs a process of comparing and analyzing the transmitted detection data with the already stored drying optimization data. As a result of the feedback, the comparative advantage of the result data and the detection data is determined.

At this time, if the values of the detection data are equal to or higher than the values of the result data, it is determined that the drying conditions of the object to be dried are sufficient and the central processing unit (P) can be terminated without the need to transmit the control secondary instruction signal. If the values of the detection data are less than the values of the result data, it is determined that the drying conditions of the object to be dried are insufficient, and the central processing unit P sends a control secondary instruction signal to the motor of the intake fan 42 to adjust the inflow velocity of air, It can be transmitted to the flow controller (C) that controls the displacement.

Therefore, the motor of the intake fan 42, which has received the control secondary instruction signal from the central processing unit P, adjusts the number of revolutions of the intake fan 42 in order to follow the drying optimization data, and the flow rate controller C is also dried. It can be terminated by adjusting the opening of the valve to follow the values of the optimum data.

Although not shown in the drawing, the flow controller (C) may be provided in a structure installed in an exhaust hole (43') formed under the airflow exhaust plate (40'), and the temperature sensor (T) is as shown in FIG. It may be provided in a structure that is installed on the inner bottom of the dryer 10, and the detector (D) is a structure that is installed at the lower end of the rotating mounting structure 21 as a portion adjacent to the drainage port 41'. In addition, the central processing unit P may be provided in a structure installed on the exterior portion of the dryer 10 as shown in FIG. 1.
