Description

Technical Field

[0001] This utility model relates to the field of corn drying, and more specifically, to a hot air drying box for drying fruit corn. Background Technology

[0002] Compared to regular corn, sweet corn kernels are fuller, have a higher moisture content, and a crisper texture. However, during the drying process, they are very prone to problems such as kernel breakage and nutrient loss.

[0003] A search revealed an existing patent (publication number: CN222951430U) disclosing a corn drying device. This device includes a drying drum, a stirring shaft, stirring plates, and an inner lining. In operation, the screen plate is removed, and the corn to be dried is injected into the drying chamber through the material inlet before the screen plate is reinstalled. The rotation of the stirring shaft causes the stirring plates to rotate as well, thus agitating the corn within the drying chamber. The heat source within the inner lining provides heating and drying, while the agitation of the stirring plates improves drying efficiency. The screen plate has a perforated structure, allowing water vapor to escape through the material inlet, thus achieving the corn drying process. The perforated structure on the stirring plates allows a large amount of corn to pass through, making the agitation of the corn by the two symmetrically arranged stirring plates more randomized, further improving drying efficiency. In summary, this application enables automated corn drying with excellent drying efficiency.

[0004] The existing drying efficiency of sweet corn is low and cannot meet the needs of large-scale production; uneven drying results in inconsistent quality of sweet corn; high energy consumption increases production costs, and the aforementioned cited patent documents do not propose any solutions to these problems.

[0005] Therefore, a hot air drying oven for drying fruit corn is proposed to address the above problems. Utility Model Content

[0011] Preferably, the drying chamber body is hinged to a door on one side, and an air outlet is provided at the upper end of the drying chamber body.

[0012] Preferably, an inner layer is provided on one side of the drying oven body, and the inner layer is provided with a middle layer and an outer layer from the inside to the outside.

[0013] Preferably, the inner layer is made of food-grade silicone material, and the middle layer and outer layer are made of thermal insulation cotton and stainless steel material, respectively.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] Compared with existing technologies, this hot air drying box for drying fruit corn avoids material accumulation by flexibly adjusting the position of the drying net according to the quantity and distribution of the fruit corn. The frame can also be angled, so that the corn continuously changes the contact angle with the hot air during the drying process. Combined with the slight vibration of the micro vibrator, the corn can be continuously turned on the drying net, reducing local obstruction and ensuring that each corn kernel receives hot air evenly. This effectively solves the problem of insufficient or excessive drying caused by material stacking under traditional single trays or fixed frames. Attached Figure Description

[0025] Example 2

[0026] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0027] In a preferred embodiment, a drying net 9 is slidably connected inside the frame 8, and a sealing plate 10 is snapped onto one side of the drying net 9; furthermore, by providing the sealing plate 10, the gap between the drying net 9 and the frame 8 is sealed during the drying process, reducing hot air leakage and ensuring stable temperature inside the chamber.

[0028] In a preferred embodiment, the drying net 9 is provided in three sets, and each drying net 9 is provided with a micro vibrator 11 on one side of its upper end; furthermore, by providing the micro vibrator 11, slight vibration is generated during operation, which drives the fruit corn on the drying net 9 to continuously turn over, avoid local shading, ensure that each corn kernel can receive hot air evenly, and improve the drying uniformity.

[0029] In a preferred embodiment, an air inlet pipe 13 is provided at the bottom of the drying chamber body 1, a fan 15 is provided inside one side of the air inlet pipe 13, an air filter 14 is provided at the upper end of the fan 15, and a heating wire 16 is fixedly provided on the inner wall of the air inlet pipe 13; furthermore, by providing an air filter 14, the air entering the air inlet pipe 13 is filtered to remove impurities and dust from the air, ensuring that the hot air entering the chamber is clean and uncontaminated, and avoiding contamination of the fruit corn.

[0030] In a preferred embodiment, a door 2 is hinged to one side of the drying chamber body 1, and an air outlet 12 is provided at the upper end of the drying chamber body 1; furthermore, by providing the door 2, the chamber can be opened and closed, making it convenient to place and take out the fruit corn to be dried, while ensuring the airtightness of the chamber during the drying process and reducing heat loss.

[0031] In a preferred embodiment, an inner layer 17 is provided on one side of the drying oven body 1, and an intermediate layer 18 and an outer layer 19 are provided in sequence from the inside to the outside of the inner layer 17; furthermore, by providing an intermediate layer 18, which is made of heat insulation cotton and located between the inner layer 17 and the outer layer 19, it has excellent heat insulation performance, which can effectively reduce the heat loss inside the oven and improve energy utilization.

[0032] As a preferred embodiment, the inner layer 17 is made of food-grade silicone material, and the middle layer 18 and the outer layer 19 are made of insulation cotton and stainless steel material, respectively. Furthermore, by providing an inner layer 17 made of food-grade silicone material, which is in direct contact with the environment inside the box, it has good high temperature resistance and safety, will not contaminate the fruit corn, and also plays a certain role in heat preservation.

[0033] The working process of this utility model is as follows:

[0034] First, after the equipment is started, the fan 15 inside the air inlet pipe 13 at the bottom of the drying chamber 1 starts working, drawing in outside air. The air first passes through the air filter 14 to remove impurities and dust, ensuring that the air entering the drying chamber is clean and preventing contamination of the fruit corn. The filtered air flows through the heating wire 16 on the inner wall of the air inlet pipe 13 and is heated to the set drying temperature, forming hot air. At the same time, the micro motor 3 starts, driving the drive wheel 4 to rotate through the output shaft. The drive wheel 4 drives the driven wheel 6 to rotate synchronously through two symmetrically arranged belts 5. The driven wheel 6 then drives the frame 8 to change angle through the connecting rod 7. The three sets of drying meshes 9 slidably connected inside the frame 8 change angle along with the frame 8. The sweet corn placed on the drying net 9 adjusts its contact angle with the hot air. After the hot air enters the drying chamber body 1 through the air inlet pipe 13, the hot air diffuses inside the chamber and comes into contact with the sweet corn on the drying net 9. The principle of heat transfer is used to remove the moisture from the surface of the corn. At the same time, the micro vibrator 11 on the upper side of the drying net 9 generates slight vibration, which causes the sweet corn to continuously turn on the drying net 9, reducing local obstruction and ensuring that each ear of corn can come into contact with the hot air evenly, avoiding local under-drying or over-drying. As the drying process proceeds, the water vapor evaporated from the sweet corn is discharged through the air outlet 12 at the upper end of the drying chamber body 1, maintaining a dry environment inside the chamber and accelerating the drying process. The three-layer structure of the drying chamber body 1 effectively reduces heat loss inside the chamber, improves energy utilization, and ensures the stability of the temperature inside the chamber. In addition, the drying net 9 inside the frame 8 can be flexibly adjusted according to the quantity and distribution of the sweet corn. The loading and unloading operation can be achieved by moving the sealing plate 10, while ensuring the airtightness of the chamber during the drying process and reducing hot air leakage. Throughout the process, all components work together to achieve efficient, uniform, and clean drying of the sweet corn through continuous supply of hot air and dynamic angle adjustment and turning of the material.

[0035] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
