Description

{A dryer}

The present invention relates to a dryer.

In general, crops are dried and distributed as processed foods or ingredients. For example, in order to process harvested peppers into pepper powder, the moisture must be removed. There are methods for removing moisture, such as using solar heat to dry them naturally, and using a dryer that artificially applies heat using electric energy.

When drying a product in a natural environment, it is difficult to quickly dry a large quantity of peppers because it is greatly affected by the weather.

Referring to Fig. 1, the dryer (10) includes a main body (16) having a drying space (17) formed inside, a tray (14) arranged in a plurality of directions in the drying space (17) and on which drying materials such as crops can be placed, a blower (12) that supplies wind to the main body (16) and the drying space (17), and a heating device (11) that increases the temperature of the wind.

As the blower (12) rotates, the outside air of the main body (16) is heated as it passes through the heating device (11). The heated wind (hereinafter referred to as warm air) passes through the passage (15) connecting the blower (12) and the drying space (17) and flows into the drying space (17) through the blower hole (13) formed on the inner periphery of the main body (16) and comes into contact with the dried material in the tray (14). The dried material in the tray (14) is dried by the warm air.

Since the dryer uses electric energy to dry crops, it has the advantage of being unaffected by the weather and drying is done quickly. However, the drying rate of the object closest to the heating device and the object furthest from the heating device differs.

Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings so that those skilled in the art can easily practice the present invention. However, the present invention may be implemented in various different forms and is not limited to the embodiments described herein. Like parts are designated by the same reference numerals throughout the specification.

Then, a dryer according to one embodiment of the present invention will be described with reference to FIGS. 2 to 8.

FIG. 2 is a perspective view showing a dryer according to one embodiment of the present invention, FIG. 3 is a schematic diagram showing the inside of the main body of FIG. 2, FIG. 4 is a schematic diagram showing the compartment of FIG. 3, FIG. 5 is a schematic diagram showing the discharge section of FIG. 2, FIG. 6 is a perspective view showing the drying module of FIG. 3, FIG. 7 is a perspective view showing the drying rack of FIG. 3, and FIG. 8 is a block diagram showing the control section of FIG. 3.

First, referring to FIGS. 2 and 3, the dryer (100) includes a main body (110), a compartment (160), a drying module (120), and a control unit (180).

A drying space (200) in which a drying object can be located is formed inside the main body (110). One side of the main body (110) is open to form an entrance (114). A door is installed in the entrance (114) so that it can be opened and closed. Since the door is opened, a drying object can be put into or taken out of the drying space (200).

An exhaust hole (112) and an inlet hole (113) are formed on the upper surface of the main body (110) to connect the drying space (200) and the outside of the main body (110). When drying a dry object, air in the drying space (200) can be exhausted to the outside of the main body (110) through the exhaust hole (112). Air outside the main body (110) can be introduced into the drying space (200) through the inlet hole (113). A cover (not shown) is arranged around the inlet hole (113) to prevent rainwater, dust, etc. from being introduced from the outside of the main body (110).

The perimeter of the main body (110) may be formed with a transparent window (not shown) that allows the drying space (200) to be visually observed. In addition, an insulating material (not shown) may be installed around the perimeter of the main body (110).

Since the detailed configuration of the main body (110) is the same as that of a container used for cargo transport of a known configuration, a detailed description is omitted.

Referring further to FIG. 4, the compartment (160) includes a bulkhead (161) and a door (162), and divides the dry space (200).

The partition wall (161) is located in the dry space (200) and is arranged along the length direction of the main body (110). The dry space (200) is divided into a first space (210) and a second space (220) by the partition wall (161).

The upper and lower surfaces of the bulkhead (161) are in contact with the inner surface of the main body (110), and the longitudinal ends are separated from the inner surface of the main body (110). Accordingly, a circulation passage (230) connecting the first space (210) and the second space (220) is formed between the two ends of the bulkhead (161) and the inner surface of the main body (110).

And, a passage (163) connecting the first space (210) and the second space (220) is formed in the center of the length of the bulkhead (161). The building material in the first space (210) can move to the second space (220) through the passage (163).

The door (162) is arranged in the passage (163) and can open or close the passage (163). When drying, the door (162) can close the passage (163). However, drying can proceed while the passage (163) is open.

Referring further to FIG. 5, the drying module (120) includes a blower (121), a heating unit (122), a frame (123), and a moving member (124), and can generate heat for drying a drying object. The drying module (120) is arranged in a first space (210) and a second space (220), respectively. The first space (210) is blocked from the entrance (114) by the drying module (120), and the second space (220) is connected to the entrance (114) of the main body (110). Accordingly, the drying object can be introduced into the second space (220) through the entrance (114) and moved to the first space (210).

The drying module (120) of the first space (210) can move air of the second space (220) to the first space (210) through the circulation passage (230), and the drying module (120) of the second space (220) can move air of the first space (210) to the second space (220) through the circulation passage (230).

The frame (123) has a rectangular prism shape formed by combining multiple rods, and a hole is formed on one side of the frame (123) into which a heating unit (122) can be combined. The side of the frame (123) is also formed by combining multiple rods, and two holes are formed at the top and bottom. Since the frame (123) has multiple holes formed, it has an open structure and does not impede the movement of air.

The movable member (124) may include a castor. The movable member (124) is coupled with the frame (123) and can move along the inner floor of the main body (110). Accordingly, the drying module (120) can move freely in the drying space (200). However, the movable member (124) may be omitted. In this case, the frame (123) may be fixed to the inner surface of the main body (110).

The heating unit (122) is connected to one side of the frame (123). The air around the heating unit (122) can be heated to a temperature of 55°C to 65°C. If the temperature is lower than 55°C, the drying efficiency is reduced, and if it exceeds 65°C, the dried material may be burned.

The blower (121) includes a housing, a fan, a motor, and a filter net and is connected to the other side of the frame (123). The blower (121) can be driven by a motor to generate wind. At this time, the air around the heated heating unit (122) can flow into the drying space (200).

Referring further to FIG. 6, the control unit (180) according to the present embodiment is arranged in the main body (110) to control the drying environment of the drying space (200).

The control unit (180) allows the operator to operate the drying module of the dryer (100). In addition, a timer, a dehumidification sensor, a temperature sensor, a camera, and a communication unit may be connected to the control unit (180).

The timer can set the operating time of the dryer (100). If the preset drying time is exceeded, the power of the dryer (100) can be cut off. Accordingly, the drying material can be prevented from burning, and fire accidents due to overload of the drying module (120) can be prevented.

The dehumidification sensor is located in the drying space (200) and can measure the humidity of the drying space (200) during drying. The dehumidification sensor can transmit a signal to the control unit when the humidity of the drying space (200) exceeds or falls below a preset value.

The temperature sensor can be located in the drying space (200) to measure the temperature. The temperature sensor can transmit a signal to the control unit (180) when the measured temperature of the drying space (200) is lower than or higher than a set value. When the temperature detected by the temperature sensor is lower than the set value, the control unit (180) can increase the temperature of the heating unit (122) to increase the temperature of the drying space (200). However, when the temperature detected by the temperature sensor exceeds the set value, the control unit (180) decreases the temperature of the heating unit (122). Accordingly, the drying space (200) can be maintained at an optimal drying temperature.

The camera is located inside the main body (110) and can capture images of the dry space (200) and transmit them to the control unit (180). The control unit (180) can store the received image information.

The communication unit can transmit information such as humidity, temperature, and image received by the control unit (180) to the manager. The manager can check the status of the dryer (100) in real time through the terminal in a place where communication is possible.

The dryer (100) according to the present embodiment may further refer to the inlet (150) (see FIG. 2). The inlet (150) is rotatably coupled to the inlet hole (113). The inlet (150) is connected to the control unit (180) and can be operated by a signal from the control unit (180). As the inlet (150) operates, the external air of the main body (110) can be introduced into the drying space (200).

Referring further to FIG. 6, the dryer (100) according to the present embodiment may further include a discharge unit (140). The discharge unit (140) includes a discharge body (141) and an opening/closing member (142), and is connected to a control unit (180) so as to discharge air in a drying space (200) to the outside of the main body (110) by a signal from the control unit (180).

The discharge body (141) is connected to the discharge hole (112) from the outside of the main body (110). The interior of the discharge body (141) is perforated along the length direction. Accordingly, the drying space (200) is connected to the outside of the main body (110) through the discharge body (141).

The opening/closing member (142) is connected to one side of the discharge body (141) and can open or block the discharge hole (112) of the main body (110). When the opening/closing member (142) is opened, air in the drying space (200) can be discharged to the outside of the main body (110) through the discharge body (141).

The discharge unit (140) may further include a dehumidifying module (not shown).

The dehumidifying module is connected to the discharge body (141) so that air discharged from the drying space (200) can pass through it. The dehumidifying module can remove water vapor contained in the air. In addition, the dehumidifying module is connected to the inlet hole (113) so that air from which water vapor has been removed can be introduced into the drying space (200). Accordingly, the object can be dried in a complete circulation manner without the need to introduce air from outside the drying space (200).

The detailed configuration of this dehumidifying module is identical to that of a known dehumidifier that separates water vapor from air, so a detailed description is omitted.

Meanwhile, a heater may be placed in the dehumidifying module. The heater may heat the air from which moisture has been removed. Since the heated air is introduced into the drying space (200), energy consumption of the drying module (120) may be minimized.

Referring to Fig. 7, the dryer (100) according to the present embodiment may further include a drying rack (130). The drying rack (130) includes a drying rack frame (133) and a strainer (131).

The drying frame (133) includes a base (135) and a pillar (136).

The base (135) is formed with a preset width. A drying movable member (134) is connected to the base (135).

A pillar (136) protrudes upward from the upper edge of the base (135). A plurality of pillars (136) are arranged along the edge. On the inner surface of the pillar (136), a plurality of catches (not shown) are formed at intervals along the length of the pillar (136).

The sieve (131) is positioned between a plurality of columns (136) and has its edge resting on a catch. A plurality of sieves (131) are arranged along the length of the columns (136). The sieve (131) is perforated to allow air to pass through. A dry object can be placed on the sieve (131).

A drying rack (130) like this can be moved in the drying space (200) by the drying rack moving member (124) and can be moved from the first space (210) to the second space (220) through the passage (163).

The following describes the operation of the dryer described above with reference to Fig. 9.

Figure 9 is a cross-sectional view showing the movement of wind according to one embodiment of the present invention.

Referring to Fig. 9, a drying rack (130) on which a drying material is placed can be introduced into the second space (220) through an entrance (114). The drying rack (130) of the second space (220) can be moved to the first space (210) through a passage (163). In this way, the temperature of the drying space (200) can be increased by operating the drying module (120) while the drying rack (130) is positioned in the first space (210) and the second space (220).

At this time, the heating unit (122) forms the surrounding air temperature to 55°C to 65°C. By operating the blower unit (121), the surrounding air of the heating unit (122) flows into the first space (210). The wind is generated in a direction parallel to the floor of the drying space (200).

The wind can come into contact with the drying material while passing through the drying rack (130) of the first space (210). The moisture of the drying material can be discharged and flow along with the air. The wind that has come into contact with the drying material in the first space (210) can be located in the drying module (120) of the second space (220) through the circulation passage (230). At this time, the air temperature around the drying module (120) of the second space (220) can be lower than the temperature generated in the drying module (120) of the first space (210).

The heating unit (122) of the second space (220) can raise the surrounding air temperature to a set temperature. By operating the blower unit (121) of the second space (220), the surrounding air of the heating unit (122) flows into the first space (210). In this way, wind can circulate in the drying space (200).

Meanwhile, the humidity sensor measures the humidity of the dry space (200) and transmits it to the control unit (180), and the control unit (180) can open and close the opening/closing member (142) according to the received humidity value to discharge moist air.

The exhaust unit (140) discharges moist air generated as drying is performed to the outside. Accordingly, the drying space (200) can maintain a low humidity state.

In addition, when the discharge unit (140) discharges wet air, the air density of the drying space (200) decreases, thereby lowering the wind pressure. The inlet unit (150) rotates to induce external air into the drying space (200), thereby maintaining the air density of the drying space (200). Even if there is only an inlet hole (113) formed in the main body (110) without the inlet unit (150), the air outside the drying space (200) can be sucked in by the drying module (120).

Meanwhile, a dehumidifying module (not shown) can be connected to the outlet (143) and the inlet hole (113). The humid air passes through the outlet (140) and flows into the dehumidifying module, and the dehumidifying module can separate water vapor from the humid air. The air from which the water vapor has been separated flows back into the drying space (200) through the inlet hole (113). Accordingly, the drying material can be dried in a complete circulation manner regardless of the humidity and temperature of the external air.

A heater may be placed in the dehumidifying module. The heater heats the air from which water vapor has been separated in the dehumidifying module, and the heated air passes through the inlet hole (113) and flows back into the drying space (200). Air flowing into the drying space (200) from the outside must be heated by the heating unit (122), but if the heater is placed, the heating unit (122) may not operate additionally. Accordingly, the load on the heating unit (122) can be reduced.

The following describes a dryer according to another embodiment of the present invention with reference to FIG. 10.

Figure 10 is a cross-sectional view showing a dryer according to another embodiment of the present invention.

The dryer (100a) according to the present embodiment may further include a moving member (111) while including the configuration according to the embodiments of FIGS. 1 to 9.

The fluid member (111) is coupled to both longitudinal edges inside the main body (110) to guide wind flowing from the first space (210) to the second space (220) and from the second space (220) to the first space (210).

The fluid member (111) can minimize the flow rate being hindered by the wind hitting the wall when passing through the edge of a vertically formed drying space (200).

Other configurations may include the configurations of the embodiments described above with reference to FIGS. 2 to 9.

The following describes a dryer according to another embodiment of the present invention with reference to FIGS. 11 and 12.

FIG. 11 is a perspective view showing a drying rack of a dryer according to another embodiment of the present invention, and FIG. 12 is a schematic diagram showing the operation of the drying rack of FIG. 11.

Referring to FIGS. 11 and 12, the dryer according to the present embodiment includes the same configuration as the embodiments of FIGS. 2 to 10. However, the drying rack has a different configuration.

The drying rack (130) according to the present embodiment includes a drying rack frame (133), a sieve (131), and a guide part (132). The drying rack frame (133) and the sieve (131) have the same configuration and operational effects as the drying rack frame and the sieve according to the embodiment of Fig. 8, so a duplicate description is omitted.

The guide part (132) is shaped like a cylinder and is positioned between adjacent trays in the vertical direction, and both ends are rotatably connected to the drying frame (133). A driving part (not shown) that generates power to rotate the guide part (132) is arranged on the drying frame (133).

The rotating guide member (132) can cause the wind passing between the trays (131) to flow in the direction of the dry object placed on the tray (131). Accordingly, the dry object can come into contact with a greater amount of wind and be dried more quickly.

Other configurations may include the configurations of the embodiments described above with reference to FIGS. 2 to 10.

The following describes a dryer according to another embodiment of the present invention with reference to FIG. 13.

Figure 13 is a schematic diagram showing a dryer according to another embodiment of the present invention.

Referring to FIG. 13, the dryer (100b) according to the present embodiment may further include a transfer unit (170) while including the configuration according to the embodiments of FIGS. 2 to 12.

The transfer unit (170) is placed on the floor of the second space (220). The transfer unit (170) can move the drying rack (130) located at the entrance (114) into the interior of the second space (220). Accordingly, the manager can place the drying rack (130) into the drying space (200) without applying physical force.

Since the detailed configuration of this transport unit (170) is the same as that of a conveyor belt of a known configuration, a detailed description is omitted.

Other configurations may include the configurations of the embodiments described above with reference to FIGS. 2 to 12.

Although the preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements made by those skilled in the art using the basic concept of the present invention defined in the following claims also fall within the scope of the present invention.
