Description

Technical Field

[0001] This utility model belongs to the field of self-heating rice production technology, and in particular relates to a drying and dehydration device. Background Art

[0002] Traditional convenience foods require soaking in boiling water before consumption. Certain groups, such as those on wilderness expeditions, tourists, military personnel, and police officers on duty, cannot eat them without boiling water. Self-heating rice, however, requires no boiling water or electricity. Simply tear open the outer packaging, pour the included purified water packet onto the heating pack, and the water and heating pack automatically mix and heat up to cook the rice and dishes.

[0003] Self-heating rice requires dehydration and drying during its preparation. Traditional drying devices dehydrate rice by placing it on a conveyor belt. However, because the rice grains are relatively fixed in position, the dehydration effect of the cold air is not uniform, resulting in poor dehydration and a large consumption of energy. Utility Model Content

[0004] This invention provides a drying and dehydration device, which aims to solve the problem mentioned in the background art that the current drying devices used in the process of dehydration affect the dehydration effect of rice grains due to the relatively fixed position of the rice grains.

The curved pipe is fixedly connected to the refrigeration pipe and fixedly connected to the cooling fins.

[0007] Preferably, a heat dissipation fin is fixedly installed on the cooling pipe, the heat dissipation fin is in contact with the cooling plate, and a fan is fixedly installed on the heat dissipation fin.

[0008] Preferably, the drying chamber is equipped with a rice grain dispersing mechanism for dispersing rice grains.

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] This utility model embodiment provides a drying and dehydration device, such as Figure 1-3As shown, the drying and dehydration device includes: a drying chamber 1 with a feed hopper 2 fixedly installed; two pulleys 3, both of which are rotatably installed inside the drying chamber 1; a conveyor belt 4, which is sleeved on the two pulleys 3; a drive motor 5, which is fixedly installed on the drying chamber 1, and the output shaft of the drive motor 5 is fixedly connected to either of the pulleys 3; a fixed frame 6, which is fixedly installed at the bottom of the drying chamber 1; a support tray 7, which is rotatably installed on the fixed frame 6 and correspondingly arranged with the conveyor belt 4; a reciprocating motor 8, which is fixedly installed on the fixed frame 6, and the output shaft of the reciprocating motor 8 is fixedly connected to the support tray 7; a collection tray 9, which is disposed on the support tray 7; and a dehydration mechanism, which is disposed on the drying chamber 1 for generating cold air to dehydrate the rice grains.

[0021] In this embodiment, the drying chamber 1 serves as the main body of the entire device, housing and protecting the internal components while providing a closed environment for better drying and dehydration. Pulleys 3 and conveyor belt 4 work together to slowly move the rice to be dehydrated within the drying chamber 1, facilitating the dehydration mechanism's work. The pre-dehydrated rice is then transferred to the receiving tray 7. The design of the conveyor belt 4 ensures even distribution of the rice during transport, providing a good foundation for the dehydration operation. A drive motor 5 drives one of the pulleys 3 to rotate, thereby driving the entire conveyor belt 4 and achieving continuous and stable rice transport. A fixing frame 6 supports the receiving tray 7, which in turn holds the collection tray 9 to receive the rice transported from the conveyor belt 4. A reciprocating motor drives the receiving tray 7 in a reciprocating motion, continuously turning the rice on the collection tray 9, increasing the contact area between the rice grains and the cold air, and improving the dehydration effect. The collection tray 9 is positioned above the receiving tray 7 for easy removal of the dehydrated rice, facilitating subsequent packaging and storage. The dehydration mechanism generates the cold air. Cold air blows through the conveyor belt 4 and the rice on the collection tray 9, causing the moisture in the rice to evaporate and achieving the purpose of dehydration.

[0022] In a further preferred embodiment of this utility model, the dehydration mechanism includes a refrigeration pipe 10, a refrigeration plate 11, a cooling fin 12, an air inlet pipe 13, an exhaust fan 14, and a curved pipe 15. The refrigeration pipe 10 is fixedly installed on the drying chamber 1, the refrigeration plate 11 is fixedly installed on the refrigeration pipe 10, the cooling fin 12 is fixedly installed inside the refrigeration pipe 10 and contacts the refrigeration end of the refrigeration plate 11, the air inlet pipe 13 is fixedly installed on the refrigeration pipe 10 and extends into the drying chamber 1, the exhaust fan 14 is fixedly installed on the drying chamber 1, and the curved pipe 15 is fixedly installed at the exhaust end of the exhaust fan 14. The curved pipe 15 is fixedly connected to the refrigeration pipe 10 and fixedly connected to the cooling fin 12.

[0023] In this embodiment, the refrigeration pipe 10, as one of the core components of the entire dehydration mechanism, performs both refrigeration and heat dissipation functions. A low-temperature environment is created by the refrigeration element 11, and the heat dissipation fins 12 are fixedly installed inside the refrigeration pipe 10, in close contact with the refrigeration end of the refrigeration element 11 to increase the heat dissipation area and improve heat dissipation efficiency. The main function of the air inlet duct 13 is to introduce the cooled and heat-dissipated air from the refrigeration pipe 10 into the drying chamber 1, ensuring that the cold air can directly act on the rice on the conveyor belt 4 for efficient dehydration. The exhaust fan 14 is fixedly installed on the drying chamber 1 and connected to the curved pipe 15, responsible for guiding external air into the refrigeration pipe 10 and simultaneously exhausting the cold air emitted by the heat dissipation fins 12 into the drying chamber 1 through the air inlet duct 13, forming a continuous airflow circulation. During operation, the refrigeration element 11 generates a low temperature, which cools the air inside the refrigeration pipe 10 through the heat dissipation fins 12. The air inlet duct guides the cooled air into the drying chamber 1. The exhaust fan 14 draws outside air into the refrigeration pipe through the curved pipe 15. In this way, the cold air can continuously and stably blow on the rice on the conveyor belt and the collection tray, achieving efficient dehydration.

[0024] In a further preferred embodiment of the present invention, a heat dissipation fin 16 is fixedly installed on the cooling pipe 10, the heat dissipation fin 16 is in contact with the cooling plate 11, and a fan 17 is fixedly installed on the heat dissipation fin 16.

[0025] In this embodiment, heat dissipation fins 16 are added to the cooling pipe 10. This design aims to further improve the heat dissipation effect of the cooling plate. The heat dissipation fins 16 are in close contact with the cooling plate 11. By increasing the contact area, the heat generated by the cooling plate can be quickly and effectively transferred to the heat dissipation fins. At the same time, a fan 17 is also fixedly installed on the heat dissipation fins 16. The activation of the fan 17 can drive airflow, forming forced convection, thereby accelerating the dissipation of heat from the heat dissipation fins 16 into the air. This design not only improves the heat dissipation efficiency of the cooling plate but also reduces the temperature of the cooling plate to a certain extent, ensuring its stable and efficient operation.

[0026] In a further preferred embodiment of this utility model, a rice grain dispersing mechanism is provided inside the drying chamber 1 to disperse the rice grains. The rice grain dispersing mechanism includes two drive wheels 18, a moving belt 19, a rotary motor 20, a rotating shaft 21, and a drive assembly 22. The two drive wheels 18 are rotatably mounted on the drying chamber 1. The moving belt 19 is sleeved on the two drive wheels 18 and is disposed between the feed hopper 2 and the conveyor belt 4. The rotary motor 20 is fixedly mounted on the drying chamber 1, and the output shaft of the rotary motor 20 is fixedly connected to the drive wheels 18. There are multiple rotating shafts 21, and the multiple rotating shafts 21 are correspondingly arranged with the moving belt 19 and the feed hopper 2. The drive assembly 22 is disposed on the drying chamber 1 to drive the rotating shafts 21 to rotate.

[0027] In this embodiment, a rice grain dispersion mechanism is added to the drying chamber 1. The main function of this mechanism is to disperse the rice grains before they enter the conveyor belt 4, ensuring uniform distribution during transport and dehydration, thus improving the dehydration effect. Rice grains falling from the feed hopper 2 first land on the moving belt 19. When the rotary motor 20 starts, it drives the drive wheel 18 to rotate, thereby moving the moving belt 19. The movement of the moving belt 19 helps guide the rice grains from the feed hopper 2 onto the conveyor belt 4, initially dispersing them in the process. The rotating shaft 21 rotates under the action of the drive assembly 22, further dispersing and stirring the rice grains on the moving belt 19, ensuring uniform distribution before entering the conveyor belt 4. The drive assembly 22 is located on the drying chamber 1 and drives the rotating shaft 21 to rotate. The rice grain dispersion mechanism effectively solves the problems of rice grain accumulation and uneven distribution that may occur during transport and dehydration, improving the dehydration effect and the quality of the cooked rice.

[0028] In a further preferred embodiment of the present invention, an exhaust fan 23 is fixedly installed on the drying chamber 1, and an exhaust pipe 24 is fixedly installed at the air inlet end of the exhaust fan 23. The exhaust pipe 24 is fixedly installed on the drying chamber 1.

[0029] In this embodiment, the main function of the exhaust fan 23 is to accelerate the airflow inside the drying chamber 1, quickly extracting humid air containing moisture, thereby achieving more efficient dehydration. When the exhaust fan 23 is working, it draws in humid air from the drying chamber 1 through the exhaust pipe 24 and then discharges it through the exhaust end of the exhaust fan 23. This design not only improves the airflow speed inside the drying chamber 1 but also helps reduce the humidity inside the drying chamber 1, thereby accelerating the dehydration process of the rice. At the same time, by continuously extracting humid air, it can also effectively prevent the rice from molding or spoiling due to excessive humidity during the dehydration process. The exhaust fan 23 and the exhaust pipe 24 can also reduce the influence of the external environment on the temperature inside the drying chamber 1 to a certain extent, making the temperature inside the drying chamber 1 more stable, which is beneficial to maintaining the quality and taste of the rice.

[0030] In a further preferred embodiment of the present invention, a collection box 25 is fixedly installed on the drying box 1, the collection box 25 is arranged corresponding to the exhaust end of the exhaust fan 23, a drain pipe is fixedly installed at the bottom of the collection box 25, and a valve is provided on the drain pipe.

[0031] In this embodiment, the main function of the collection box 25 is to collect and temporarily store moisture from the humid air discharged from the exhaust fan 23. Since the exhaust fan 23 generates a large amount of moisture-containing air, without proper collection measures, this moisture may be directly released into the environment, causing unnecessary humidity increases or adverse effects on the surrounding environment. The collection box 25 effectively prevents this from happening. Furthermore, a drain pipe is fixedly installed at the bottom of the collection box 25, and a valve is installed on the drain pipe. When the moisture in the collection box 25 accumulates to a certain level, the valve can be opened to allow the moisture to drain through the drain pipe, thereby emptying the collection box 25 and enabling its reuse. This design not only facilitates the cleaning and maintenance of the collection box 25 but also ensures the continuous and stable operation of the entire drying and dehydration device.

[0032] In a further preferred embodiment of this utility model, both the conveyor belt 4 and the moving belt 19 are provided with support plates, the tray 7 is fixedly installed with a locking block, and the storage tray 9 is provided with a slot corresponding to the locking block.

[0033] In this embodiment, support plates are provided on both the conveyor belt 4 and the moving belt 19. The main function of these support plates is to increase the stability of the rice during transport and provide support for the conveyor belt 4 and the moving belt 19. A locking block is fixedly installed on the tray 7. The locking block's function is to correspond and cooperate with the slot on the collection tray 9, achieving quick and accurate docking between the tray 7 and the collection tray 9. When the tray 7 moves above the collection tray 9, the locking block automatically engages in the slot, ensuring a stable connection between the two. This design not only simplifies the operation process but also improves the accuracy and efficiency of docking. The slot design allows the locking block to engage smoothly, achieving a tight connection between the tray 7 and the collection tray 9.

[0034] In summary, compared with related technologies, the addition of a rice grain dispersion mechanism achieves uniform dispersion of rice grains, improving the uniformity and efficiency of rice during transport and dehydration. This not only helps improve the dehydration effect but also ensures the quality and taste of the rice. The introduction of an exhaust fan and suction pipe accelerates airflow within the drying chamber, reducing humidity and thus achieving more efficient dehydration. The collection box design allows moisture from the humid air exhausted by the exhaust fan to be collected and discharged, preventing increased ambient humidity and potential impact on the surrounding environment. Furthermore, support plates on the conveyor belt and moving belt increase the stability of the rice during transport. The locking and slot design between the tray and the collection tray simplifies the operation process and improves the accuracy and efficiency of docking.
