Description

Technical Field

[0001] This utility model belongs to the field of raisin production technology, and specifically relates to a ventilation device for simulating natural wind in raisin production. Background Technology

[0002] Raisins, a nutritious and uniquely flavorful food, are beloved by consumers. One key step in their traditional production process is natural air drying in a ventilated room. During this process, raisins gradually lose moisture under high temperatures and with the help of natural wind, reaching an ideal dry state while preserving the grape's natural color and sweet taste. However, natural air drying is heavily reliant on external weather conditions, especially suitable wind and temperature, making it difficult to effectively control the production cycle and quality of raisins.

[0003] While high temperatures promote rapid evaporation of moisture, the frequency and intensity of natural wind are unpredictable and unreliable. In windless or insufficiently windy conditions, the drying efficiency of raisins decreases significantly, not only prolonging the production cycle but also potentially leading to quality degradation due to prolonged exposure to high temperatures, such as darkening of color and deterioration in taste. Furthermore, natural air drying is susceptible to adverse factors such as rain and dust, further increasing the uncertainty and cost of the production process.

[0004] In conclusion, designing a ventilation device for raisin production that can simulate natural wind or generate natural wind using external structures is particularly important and has a certain market demand. Summary of the Invention

[0005] To address the shortcomings of the existing technology, this invention provides a ventilation device for simulating natural wind during raisin making, thereby solving the aforementioned problems.

[0006] This utility model discloses a ventilation device for simulating natural wind in raisin production, comprising a ventilation chamber with an aisle inside. Several layers of drying rods are symmetrically arranged on both sides of the aisle, and the drying rods are folded and connected to the inner wall of the ventilation chamber. A door is opened on one side of the ventilation chamber, connecting to one end of the aisle. A drying chamber is arranged on the other side of the ventilation chamber, opposite the door. A grid is arranged between the drying chamber and the ventilation chamber. A natural fan facing one end of the aisle is arranged in the drying chamber, and a finned heating tube is arranged in the drying chamber. Several ventilation holes are arranged around the ventilation chamber and on the door.

[0007] Furthermore, insect-proof strips are installed around the ventilation room and on the door, and the insect-proof strips are rounded right-angled lines.

[0008] Furthermore, each of the drying rods is hinged to a mounting base at its end, and the mounting base is screwed onto the ventilated roof. A magnet is provided on both the drying rod and the mounting base.

[0009] Furthermore, each of the aforementioned drying rods has several hanging grooves at its bottom.

[0010] Furthermore, the ventilated room is provided with a sloping roof.

[0011] Furthermore, a hanging net is provided on the ventilation hole.

[0012] Compared with existing technologies, this ventilation device, through its integrated design, effectively simulates the natural air-drying environment, significantly improving the efficiency and quality stability of raisin production, while reducing weather dependence and achieving high-efficiency production. This brings significant economic benefits and industrial upgrading to the raisin production industry. Attached Figure Description

[0019] To better understand this utility model, the following is in conjunction with... Figures 1 to 5 The embodiments of this utility model will be explained in detail below.

[0020] It should be noted that the directions "front, back, left, right, up, down" mentioned in the text are all relative to the direction of the text. Figure 1 The directions are based on "front, back, left, right, up, down".

[0021] This utility model discloses a ventilation device for simulating natural wind in raisin making, comprising a ventilation chamber 1. The ventilation chamber 1 is constructed using traditional red bricks, architectural forms, or prefabricated houses. A passageway 2 is provided inside the ventilation chamber 1, and several layers of drying rods 3 are symmetrically installed on both sides of the passageway 2 for hanging grapes for drying. The drying rods 3 are folded to the inner wall of the ventilation chamber 1, allowing them to be folded away when not in use, saving space. The top of the ventilation chamber 1 is designed as a sloping roof 14, which facilitates drainage and reduces the impact of rainwater on the internal environment.

[0022] Each drying rod 3 has a mounting base 11 hinged to its end, which is securely mounted to the inner wall of the ventilation chamber 1 with screws. A magnet 12 is installed on both the drying rod 3 and the mounting base 11. When the drying rod 3 is extended, the two magnets 12 attract each other, which helps the drying rod 3 remain stable when unfolded and facilitates quick disassembly and cleaning. Several hanging slots 13 are provided at the bottom of the drying rod 3 for hanging grapes, ensuring that the grapes receive even airflow during the drying process.

[0023] A door 4 is located on one side of the ventilation chamber 1, while a drying chamber 5 is built on the other side. The drying chamber 5 is separated from the ventilation chamber 1 by a grating 6. The grating 6 is designed to ensure ventilation while preventing the grapes from being directly exposed to excessive wind. A natural fan 7 is installed inside the drying chamber 5, facing one end of the aisle 2, to simulate natural wind and accelerate the drying process of the raisins. Simultaneously, finned heating tubes 8 are also installed inside the drying chamber 5 to provide additional heat when necessary to cope with low temperatures or high humidity conditions.

[0024] Several ventilation holes 9 are installed around the ventilation room 1 and on the door 4 to ensure air circulation and improve drying efficiency. Netting is installed over the ventilation holes 9 to prevent birds from entering the ventilation room 1 and pecking at the grapes, while maintaining ventilation. In addition, insect-proof strips are installed around the ventilation room 1 and on the door 4. These strips are rounded right-angle lines 10, which are both aesthetically pleasing and practical, further enhancing the insect-proof effect.

[0025] The usage and principle of this utility model:

[0026] First, the trolley carrying the grapes enters the ventilation room 1 through door 4 and passes through corridor 2 to reach the depths of the ventilation room 1. Next, the drying racks 3 are unfolded, and the grapes are hung on the hanging slots 13 of the racks 3 until all racks 3 are full. Then, door 4 is closed, and the natural fan 7 and finned heating tubes 8 in the drying chamber 5 are turned on (the heating function can be turned on or off depending on the weather conditions), allowing air to circulate within the ventilation room 1, simulating a natural wind environment. During this process, air circulation is maintained through the ventilation holes 9 around the ventilation room 1 and the ventilation holes 9 on door 4, accelerating the drying process of the raisins. During the drying process, the drying status of the grapes can be checked periodically, and the speed of the natural fan 7 and the heating temperature can be adjusted as needed. When the raisins reach the ideal dryness, the natural fan 7 and finned heating tubes 8 are turned off, and the raisins are removed one by one from the drying racks 3. The drying racks 3 are then folded up, and the entire production process is complete after all the raisins have been collected.
