Description

Technical Field

[0001] This invention relates to the field of sweet potato drying technology, specifically to a circulating ventilation sweet potato drying room. Background Technology

[0002] Sweet potatoes are annual herbaceous plants belonging to the Convolvulaceae family and the Ipomoea genus. They are an important dual-purpose crop, used for both food and vegetables, and have high nutritional value, diverse ways of consumption, and economic value, making them a common healthy food ingredient. To facilitate the drying and storage of sweet potatoes, a sweet potato drying room is needed. A sweet potato drying room is a specialized piece of equipment used to dehydrate fresh sweet potatoes to a moisture content of 15% to 25% in a controlled high-temperature and low-humidity environment.

[0003] Existing sweet potato drying rooms use air pumps to draw outside air into heating equipment, heat it, and then send it into the sweet potato drying room. This increases the surface and internal temperature of the sweet potatoes, breaks the binding force between water and cells, and allows water to diffuse from the inside of the sweet potato to the surface. Then, a low-humidity airflow carries away the water vapor that evaporates from the surface until the moisture content drops to the target value.

[0004] However, continuously drawing in outside air requires a significant amount of energy from the heating equipment, and the drawn-in outside air cannot be heated to the required temperature instantly. Therefore, the heating time of the drawn-in air needs to be controlled, resulting in intermittent baking in the drying room. Furthermore, the heated gas still carries a large amount of heat after baking the sweet potatoes. Directly expelling this gas would cause heat loss, which is detrimental to the baking process. Summary of the Invention

[0005] To address the aforementioned issues, a circulating ventilation sweet potato drying chamber is provided. Through the suction branch pipe at the suction pipe, in conjunction with the suction pump, air inlet pipe, and insulation plate, heated gas can be circulated and evenly transported, continuously providing heated gas to the drying chamber body. This achieves circulating ventilation of the gas within the drying chamber, reducing heat loss. A circulating water box and a dehumidifier box are provided to easily remove moisture from the circulating ventilation gas, ensuring effective drying of the sweet potatoes and facilitating the drying process.

[0006] To address the problems of the prior art, the present invention provides a circulating ventilation sweet potato drying room, including a drying room body and a suction pump fixedly installed on one side of the drying room body;

Several slots are provided at equal intervals along the length direction for each air supply branch pipe and suction branch pipe. Heating pipes are provided on both sides of each air supply branch pipe.

[0009] The drying chamber body is provided with a baking chamber, and the two sides of the baking chamber extend laterally to form a heating chamber and an installation chamber. The air supply branch pipe and the heating pipe are located in the heating chamber, and the suction branch pipe is located in the installation chamber.

[0010] Preferably, a heat insulation plate is provided between the baking cavity, the heating cavity, and the installation cavity.

[0030] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0031] See Figure 1 and Figure 2 As shown, a circulating ventilation sweet potato drying room includes a drying room body 1 and a suction pump 2 fixedly installed on one side of the drying room body 1.

[0032] It also includes an air inlet pipe 2a and an air delivery pipe 2b connected to the suction pump 2, and a suction pipe 3 is also provided on the side of the suction pump 2 where the air inlet pipe 2a is provided.

[0033] It should be noted that during use, the gas is drawn from the air inlet pipe 2a at the suction pump 2 to the air supply pipe 2b, and then the air supply pipe 2b delivers the drawn gas into the drying chamber body 1.

[0034] See Figure 1-5 As shown, the portion of the air supply pipe 2b and the suction pipe 3 extending along the height direction of the drying chamber body 1 is a vertical pipe section. Several air supply branch pipes 2b1 and suction branch pipes 3a are respectively arranged horizontally along the length direction on one side of the two vertical pipe sections. Several slots are equally spaced along the length direction for the air supply branch pipes 2b1 and the suction branch pipes 3a. Heating pipes 4 are arranged on both sides of each air supply branch pipe 2b1.

[0035] The drying chamber body 1 is provided with a baking chamber, and the two sides of the baking chamber extend laterally to form a heating chamber and an installation chamber. The air supply branch pipe 2b1 and the heating pipe 4 are located in the heating chamber, and the suction branch pipe 3a is located in the installation chamber.

[0036] It should be noted that during operation, the air supply pipe 2b disperses the gas drawn in by the suction pump 2 through the vertical pipe connected to it into each air supply branch pipe 2b1, and then the air supply branch pipe 2b1 discharges the gas, so that the gas is evenly dispersed in the heating chamber and heated by the heating pipe 4 of the heating chamber before being sent into the baking chamber to bake the sweet potatoes.

[0037] See Figure 3 and Figure 4 As shown, a heat insulation plate 5 is provided between the baking cavity, the heating cavity, and the installation cavity. Several ventilation openings are opened horizontally through the heat insulation plate 5. The heat insulation plate 5 and the heating pipe 4 are both installed inside the drying chamber body 1.

[0038] The baking cavity has multiple baking racks 6 arranged vertically, and each baking rack 6 is fixedly connected to the inner wall of the drying chamber body 1.

[0039] It should be noted that the heat insulation plate 5 at the heating chamber allows the gas to diffuse within the chamber after entering, thus facilitating heating by the heating pipe 4. Simultaneously, the heated gas is further distributed evenly within the baking chamber through the vents at the heat insulation plate 5, ensuring sufficient contact between the gas and the sweet potatoes to remove moisture. The heat insulation plate 5 at the heating chamber prevents the sweet potatoes or impurities on their surface from being sucked into the suction pipe 3a when the wind speed is too high, and also interrupts the suction path of the suction pipe 3a, allowing it to evenly draw in the heated gas within the baking chamber. The baking rack 6 is used to separate and arrange the sweet potatoes to be baked, facilitating the baking process.

[0040] See Figure 5-7 As shown, a dehumidification tank 7 is provided at one end of the suction pipe 3, and a cold water box 7a and a dehumidification box 7b are arranged sequentially from bottom to top in the dehumidification tank 7.

[0041] The end of the suction pipe 3 connected to the dehumidification tank 7 is located on the lower side of the cold water box 7a, and the end of the air inlet pipe 2a connected to the dehumidification tank 7 is located on the upper side of the dehumidification box 7b.

[0042] It should be noted that when the suction pump 2 draws the heated gas from the drying chamber body 1 through the air inlet pipe 2a and the suction pipe 3, the heated gas is introduced into the dehumidification tank 7 and comes into contact with the cold water box 7a, causing the moisture in the heated gas to condense. At this time, the moisture and some heat in the gas are retained, and the remaining heated gas is dehydrated a second time through the dehumidification box 7b before being sequentially sent into the air supply pipe 2b, the air supply branch pipe 2b1, and the heating chamber, thereby shortening the gas heating time, reducing heat loss, and improving baking efficiency.

[0043] See Figure 2 As shown, one end of the air inlet pipe 2a is horizontally connected to the air supply pipe 2a1, and the air supply pipe 2a1 is equipped with a solenoid valve 2a2.

[0044] It should be noted that the make-up air pipe 2a1 and the solenoid valve 2a2 are designed to replenish the gas lost during the extraction process, thereby ensuring the purpose of circulating ventilation in the drying chamber 1.

[0045] See Figure 2 and Figure 5-8 As shown, a water storage tank 8 is provided at the bottom of the water tank 7, and a water pump 8a is installed on the top of the water storage tank 8.

[0046] The water pump 8a has its delivery end and pumping end connected to the cold water box 7a and the water storage tank 8 via connecting pipes, respectively. The end of the cold water box 7a away from the connecting pipe is connected to the water storage tank 8 via a drain pipe.

[0047] It should be noted that, in order to ensure the dewatering effect of the cold water box 7a, the water pump 8a is started. The water pump 8a transports the water source in the water storage tank 8 to the cold water box 7a through the connecting pipe and then guides it back to the water storage tank 8 through the drain pipe, so as to realize the water circulation and avoid the water source in the cold water box 7a being heated by the heat-generating gas, which would affect the dewatering effect.

[0048] See Figure 2 and Figure 6 As shown, the dewatering tank 7 and the water storage tank 8 are both fixedly installed with the drying chamber body 1, and the bottom of the dewatering tank 7 is also connected to an outlet pipe.

[0049] It should be noted that the outlet pipe is designed to drain the liquid that drips from the cold water box 7a into the water removal tank 7.

[0050] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
