{Energy-saving drying device using waste heat}

The present invention relates to an energy-saving drying device using waste heat. More specifically, the present invention relates to an energy-saving drying device using waste heat that can effectively dry a drying material with minimal energy consumption by using the waste heat of a dehumidifying blower.

Usually, agricultural and marine products or food ingredients such as meat are dried to create a specific taste and nutrients or for long-term storage before distribution and reprocessing. Representative examples include jujubes, peppers, radishes, persimmons, mushrooms, beef jerky, and squid. To dry these agricultural and marine products, natural drying using sunlight and wind is used. However, natural drying takes a long time, so productivity is low, it requires a large space, and dust and various foreign substances adhere during the drying process, lowering the quality of the product. It cannot be done on rainy or humid days, and producers must frequently turn over the agricultural and marine products to be dried.

Accordingly, in the previously disclosed patent registration No. 10-1314576, a drying room is provided to form a circulation passage of dry air inside a housing; a drying storage unit formed to be able to store agricultural products to be dried by being accommodated in the drying room and formed to form an upward air current of dry air inside the drying room; a far-infrared heater installed at a predetermined interval on the circulation passage located at an upper portion of the drying room and provided to radiate high-temperature far-infrared rays and form dry air; a blower unit configured to circulate the dry air and form a horizontal air current of dry air inside the drying room by comprising a plurality of first blower fans installed on one side of the drying room and a plurality of second blower fans installed on the other side of the drying room opposite to the first blower fans; at least one dehumidifying unit installed in the housing and provided to remove moisture contained in the dry air circulating along the circulation passage; And a technology including a control unit configured to control the operation of the far-infrared heater, the blower, and the dehumidifier according to preset information has been pre-registered, but it has many problems, such as high power consumption, the outside of the object to be dried is quickly dried by the hot air but the inside is not dried well, and the shape or color of the object to be dried is changed, reducing marketability.

In addition, in another prior art, registered patent No. 10-0796354, a drying device for drying grains or agricultural products is configured with a blower fan that sucks air inside a drying room and supplies it to the drying device, an evaporator that liquefies the water vapor in the air by taking external heat from the water vapor in the air as the refrigerant evaporates to dehumidify it, a condenser that radiates heat to the outside as the high-temperature and high-pressure refrigerant in the dehumidified air condenses, thereby increasing the temperature of the dehumidified air, a compressor that forms high-temperature and high-pressure refrigerant that enters the condenser, an expander that forms low-temperature and low-pressure refrigerant that enters the evaporator, and an outdoor heat exchanger that is connected between the condenser and the compressor through a different path from the expander and the evaporator and is installed to bypass, and a technology is proposed that allows the circulation cycle to be changed by using two valves installed in a refrigerant pipe to which the outdoor heat exchanger is connected, a valve installed between the condenser and the expander, and a valve installed between the evaporator and the compressor. However, the volume and weight increase due to the configuration of the compressor and the condenser, This had the disadvantage of significantly lowering energy efficiency, with power consumption at least 1.5kW.

The present invention relates to an energy-saving drying device using waste heat, which is composed of a drying room (100), a blower room (200), a dehumidifying blower (300), a dehumidifying module (400), a lower passage (500), a humidity maintenance module (600), an ultraviolet lamp (700), and a control module (800), which quickly and evenly dries a drying material without destruction or deterioration of nutrients by means of a method of heat storage of a ceramic heat storage panel and moisture condensation removal by a dehumidifying module, and which is structurally improved to recycle waste heat generated from a motor of a dehumidifying blower as circulating air heating heat, thereby effectively improving greenhouse gas emissions as well as saving energy.

First, the drying room (100) according to the present invention has an entrance that is opened and closed by a door (110), a hot water pipe (120) is installed on at least one of the inner floor and side walls, and a ceramic heat storage panel (130) that is heated by the hot water pipe (120) and emits far infrared rays is provided so as to be in contact with the hot water pipe (120).

The above ceramic heat storage panel (130) is formed with a composition including a ceramic material containing yellow clay, and when heated by a hot water pipe (120), a large amount of far infrared rays are output like a gudeulbang, and it is equipped to be dried by radiant heat.

Accordingly, drying is carried out from the inside of the object, so the object does not burn, the moisture is released quickly, there is almost no destruction of shape, color, and nutrients, and odor is also eliminated. In addition, blind spots to heat are minimized within the drying room (100), so that the entire area is evenly dried, and thus it can be widely used as a drying device for laundry generated in agricultural and marine products as well as companies, schools, pensions, postpartum care centers, saunas, hospitals, etc.

Referring to FIGS. 2 and 3, the ceramic heat storage panel (130) is formed of a ceramic containing yellow clay, and comprises a panel body (132) in which a pair of panels are arranged facing each other so as to surround a hot water pipe (120) from the inside and the outside, 1st, 2nd, 3rd, and 4th straight embedding lines (L1)(L2)(L3)(L4) arranged in a row so that 4 of them form a group on one side of the panel body (132) so as to accommodate the hot water pipe (120), 1st, 2nd, and 3rd curved embedding lines (C1)(C2)(C3) connecting one end of the 1st, 2nd, 3rd, and 4th straight embedding lines (L1)(L2)(L3)(L4) in an arch shape, and a 4th curved line connecting the other end of the 2nd and 3rd straight embedding lines (L2)(L3) in an arch shape. It includes a fifth curved embedding line (C5) that connects the embedding line (C4) and the fourth straight embedding line (C4) and the first straight embedding line (L1) of another group adjacent to it in an arch shape, an extended curved embedding line (C6) that connects the first and fourth straight embedding lines (L1)(L4) that are connected to the first and third curved embedding lines (C1)(C3) to each other, and an extended straight embedding line (L5) that extends to one end of the first, second, third, and fourth straight embedding lines (L1)(L2)(L3)(L4) that are connected to the fourth and fifth curved embedding lines (C4)(C5) and opens to the outside of the panel body (132).

And, using the single standard ceramic heat storage panel (130) mentioned above, the hot water pipe (120) can be organized into various structures. For detailed descriptions thereof, refer to FIGS. 4 and 5 described below.

In Fig. 4 (a), the hot water pipe (120) may be arranged in a zigzag direction so as to pass through the first to fourth straight embedding lines (L1)(L2)(L3)(L4) by changing direction at the first, third to fifth curved embedding lines (C1)(C3)(C5) while the ceramic heat storage panel (130) is horizontally continuously installed, or, as in Fig. 4 (b), the hot water pipe (120) may be arranged in a zigzag direction so as to pass through the first and fourth straight embedding lines (L1)(L4) by changing direction at the extended curved embedding line (C6) and the fifth curved embedding line (C5).

In Fig. 5, the ceramic heat storage panels (130) are constructed in upper and lower rows so as to be horizontally continuous and longitudinally symmetrical, and the first, second, third, and fourth straight embedding lines (L1)(L2)(L3)(L4) of the ceramic heat storage panels (130) arranged in the upper and lower rows are connected to each other by an extended straight embedding line (L5).

And, as in Fig. 5 (a), the hot water pipe (120) is arranged in a zigzag direction so as to change direction from the extended straight embedding line (L5) and the first and third curved embedding lines (C1)(C3) and pass through the first to fourth straight embedding lines (L1)(L2)(L3)(L4), or as in Fig. 5 (b), the hot water pipe (120) is arranged in a zigzag direction so as to change direction using at least one of the extended straight embedding line (L5), the extended curved embedding line (L6) and the first and third curved embedding lines (C1)(C3) and pass through the first and second straight embedding lines (L1)(L2) or the third and fourth straight embedding lines (L3)(L4).

Meanwhile, as shown in Fig. 3, elastic insulating balls (134) can be inserted at predetermined intervals into the straight or curved buried line where the hot water pipe (120) is not installed to close the empty space.

Accordingly, heat loss through straight or curved buried lines where the hot water pipe (120) is not installed is blocked, thereby improving the heating efficiency of the ceramic heat storage panel (130) using the hot water pipe (120).

The blower room (200) according to the present invention forms an independent compartment by a partition wall (220) installed inside the drying room (100), a blower hole (222) is formed in the partition wall (220), and a blower fan (210) is installed inside to vortex the air inside the drying room (100).

FIG. 8 is a drawing showing a detailed configuration of a blower fan of an energy-saving drying device of the present invention. The blower fan (210) includes a rotation shaft (211) that is arranged horizontally and rotated by a motor, and blades (212) that are radially arranged equiangularly around the rotation shaft (211).

At this time, the blade (212) is formed radially around the rotation axis (211) by combining the main wing (213), the multi-wing (214) which is spaced apart in front of the main wing (213) and formed with a reduced width compared to the main wing (213), the middle wing (215) which connects the main wing (213) and the multi-wing (214) at the end, and the main wing (213), the multi-wing (214) and the middle wing (215). 'Includes the brother wind direction path (216).

And when the above blower fan (210) rotates, the blower fan (210) blows air in all directions due to the difference in length between the main blade (213) and the multi-blade (214). 'The air is blown radially through the fan (216) to effectively stir the air inside the blower room (200).

It is preferable that the main blade (213) and the multi-blade (214) of the above blade (212) are formed with a deviation of 15 to 30 mm, and the air inside the drying room (100) is quickly and evenly circulated by the blade (212), thereby minimizing the temperature deviation inside the dryer (100), thereby eliminating the blind spot of the drying wind.

Figure 6 is a configuration diagram showing a dehumidifying blower and a dehumidifying module of an energy-saving drying device using waste heat according to one embodiment of the present invention. The dehumidifying blower (300) according to the present invention is equipped with a circulation duct (310) to suck in air inside the drying room (100) and output it to the blower room (200).

The above dehumidifying blower (300) is installed on the outer top plate of the drying room (100) with a specification of 1.2 Kw/h, the intake of the dehumidifying blower (300) is connected to the top plate of the drying room (100), and the discharge port is installed on the top plate of the blower room (200).

The above dehumidifying blower (300) sucks in moist air inside the drying room (100) and discharges it into the blower room (200), and while the moist air is moving into the blower room (200), moisture is condensed and removed by the dehumidifying module (400) described later.

In addition, the above dehumidifying blower (300) heats the circulating air with the heat generated by the motor during operation, so that the drying process can be continuously operated in power-saving mode by supplementing the heat storage of the ceramic heat storage panel (130) while the heating of the drying room (100) by the hot water pipe (120) is turned off.

In fact, the heat generated by the above-mentioned dehumidifying blower (300) motor is about 80°, and accordingly, the temperature of the dehumidified air re-introduced into the blower room (200) is 30° to 35°. Since this heat is continuously circulated through the inside of the drying room (100), even if the hot water pipe (120) is initially turned on and turned off 10 minutes later, drying can be performed for a long time of more than 24 hours, and energy efficiency is improved by this motor waste heat recycling cycle.

Referring to FIG. 6, a dehumidifying module (400) according to the present invention includes a first Peltier element (410) that condenses moisture contained in air transported through the circulation duct (310), and a first drain pipe (420) that discharges condensed water condensed by the first Peltier element (410).

The above first Peltier element (410) cools wet air to 18 to 22°C, and water heavier than air is condensed due to the temperature difference and discharged through the first drain pipe (420), and dry air dried by the dehumidifying module (400) is reintroduced into the drying room (100) through the blower room (200), forming a circulation cycle.

The drying device of the present invention configured as described above is significantly reduced in volume and weight compared to an air conditioning structure composed of a conventional compressor and condenser due to the drying system using the Peltier element, and can be operated with low power by using a thermoelectric element instead of the conventional 1.5kW power consumption, thereby dehumidifying and cooling the humid and hot air inside a drying room.

In addition, with only 2.3 kw/h of power, including a 1.2 kw/h dehumidifying blower (300), a 750 W blower motor driving a blower fan (210), and a 360 W Peltier element, it is possible to continuously dry or cook a large volume of material weighing more than 1,500 kg, thereby drastically reducing the energy consumed in the drying process.

FIG. 7 is a diagram showing a configuration of a cold air generating module in an energy-saving drying device using waste heat according to the present invention. A cold air generating module (430) according to the present invention is installed in an air vent (222) of the partition wall (220) and may further include a second Peltier element (432) to cool the wind output from the blower fan (210).

In this way, the first Peltier element (410) can be used for the purpose of dehumidification by temperature difference, or, when used together with the second Peltier element (432) constituting the cold air generation module (430), it can be configured to cool the circulated air to below 35°C to create optimal low-temperature drying conditions similar to sea breeze, so that, depending on the type of material to be dried, it has the advantage of being able to perform both low-temperature drying below 35°C and high-temperature drying using dehumidification by temperature difference.

Figure 9 is a configuration diagram showing the lower passage of an energy-saving drying device. The lower passage (500) according to the present invention is formed on the floor side of the drying room (100) and is configured to be connected to the outside.

And the lower passage (500) is opened and closed by a valve (510), and at this time, the lower passage (500) is connected to a smoke generator (520) to inject smoke, connected to a steam generator (540) to inject steam, or connected to a second drain pipe (530) to discharge liquid foreign substances generated within the drying room (100).

In this way, after the above-mentioned drying material is dried, a smoke generating unit (520) is connected to the lower passage (500) to inject smoke, enabling simple smoking cooking. In addition, a steam generating unit (540) is connected to the lower passage (500) to control the humidity of the drying material after drying, thereby preventing the surface from becoming hard or tough.

Referring to FIG. 1, the humidity maintenance module (600) according to the present invention is equipped with a nozzle (620) that detects the humidity inside the drying room (100) and sprays fog when the humidity is below a set value.

The above nozzle (620) selectively supplies moisture and sterilizing solution (negative ion calcium mineral water or nitric oxide solution) for humidity control, thereby suppressing bacterial growth and odor of fish and meat, thereby improving the marketability of dried products.

Referring to Fig. 9, an ultraviolet lamp (700) may be installed on the inner ceiling and side walls of the drying device provided in the present invention. In this case, by the action of ultraviolet rays output from the ultraviolet lamp (700), harmful bacteria inside the drying room (100) are sterilized by 99.9%, so that the object to be dried is prevented from being contaminated by bacteria, and the inside of the drying room (100) is always kept clean, and even when drying a small amount of a variety of objects to be dried, the phenomenon of quality deterioration due to mixing of odors is prevented.

The control module (800) according to the present invention controls the output of one or more of the hot water pipe (120), blower fan (210), dehumidifying blower (300), dehumidifying module (400), cold air generating module (430), and humidity maintenance module (600), and is equipped with a communication module so as to be remotely controlled by a user terminal.

And when the aforementioned cold air generation module (430) is applied, the control module (800) is equipped to operate in a high temperature drying mode and a low temperature drying mode.

At this time, the high-temperature drying mode is provided so that the ceramic heat storage panel (130) is heated to a predetermined temperature using a hot water pipe (120) and then turned off, and the motor heat generated by the ceramic heat storage panel (130) and the dehumidifying blower (300) is circulated by the blower to dry the object at high temperature. During high-temperature drying, if the humidity in the air is higher than the set value, the dehumidifying module (400) is turned on, and if the humidity is lower than the set value, the humidity maintenance module (600) is turned on.

And, the low-temperature drying mode is provided by turning on the dehumidifying blower (300) and the dehumidifying module (400) to remove humidity in the air while circulating the air inside the drying room (100), and turning on the second Peltier element (430) to output cold air through the air blower (222) to dry the object at low temperatures.

In this way, due to the heat storage of the ceramic heat storage panel (130) and the moisture condensation removal method by the dehumidification module (400), the drying material can be dried quickly and evenly, and various types of drying can be done without destruction or deterioration of nutrients, ranging from agricultural and marine products such as semi-dried fish, various types of seaweed, and red peppers, to processed foods and pharmaceuticals for industrial use. In particular, the structure is improved to recycle waste heat generated from the motor of the dehumidification blower as circulating air heating heat, so that energy savings and greenhouse gas emissions can be effectively improved.

Figure 10 is a configuration diagram showing a stirring module of an energy-saving drying device. A carrier (140) for storing a drying material in multiple stages is installed in the drying room (100), and the carrier (140) is provided so that the position of the drying material can be varied by a stirring module (150).

The carrier (140) above includes four vertical bars (142) having rings (141) formed at the upper end, and a horizontal bar (144) having both ends joined to the vertical bars (142) by hinges and arranged in multiple stages in the longitudinal direction of the vertical bars (142) on which grills (143) containing the drying material are loaded.

In addition, the stirring module (150) includes a rotating plate (151) installed on the ceiling inside the drying room (100) and having a rotation angle controlled by a motor, and four hooks (152) arranged at 90° equal intervals at the bottom of the rotating plate (151) and mounted on a ring (141) of a carrier (140).

At this time, the above-mentioned rotating plate (151) may rotate continuously or may rotate intermittently at regular time intervals.

According to the above configuration, since the object to be dried located in the carrier (140) rotates, there is an advantage in that the drying state is not biased due to the influence of the blower fan (210) installed only on one side of the drying room, and the drying process of the object to be dried can be evenly and uniformly performed.

In addition, four load cells (153) may be further formed to detect the weight of four longitudinal bars (142) installed between the rotating plate (151) and the catch (152) and placed on the catch (152) at positions corresponding to the four corners of the grill (143).

Looking at the operating state, the load cell (153) detects the weight loss amount during the drying process at predetermined time intervals based on the weight of the object to be dried before drying, and is provided so that the bar (142) at the position with the smallest weight loss amount is switched with the bar (142) at the position with the largest weight loss amount by the operation of the rotating plate (151).

And, after the position-changing operation of the above-mentioned bar (142) is performed, the load cell (153) detects the weight of the object to be dried, and after a predetermined time has elapsed, the load cell (153) re-detects the weight of the object to be dried and calculates it with the previously detected value, and the operation of switching the bar (142) at the position with the smallest weight reduction with the bar (142) at the position with the largest weight reduction is repeated.

Accordingly, a high-quality dried product with a more even and precise drying state can be obtained without constantly operating the rotating plate (151).

As described above, the detailed description of the present invention has described the most preferred embodiment of the present invention, but various modifications may be made within the scope that does not depart from the technical scope of the present invention. Therefore, the protection scope of the present invention should not be limited to the above-described embodiment, but should be recognized as the protection scope extending to the technologies of the patent claims described below and equivalent technical means from these technologies.
