Description

Technical Field

[0001] This utility model relates to the technical field of raisin processing equipment, and in particular to a drying device for raisin cleaning and production. Background Technology

[0002] In the processing of raisins, timely drying after washing is the core step in ensuring their quality and preventing spoilage. Raisins are rich in sugar, and after washing, a large amount of moisture adheres to their surface. If they are not dried in time, they are highly susceptible to microbial growth. Timely drying protects the quality and safety of raisins from multiple dimensions, laying a solid foundation for subsequent storage, transportation, and consumption. From a moisture control perspective, timely drying can quickly reduce the moisture content of raisins after washing, restoring them to a suitable safe storage moisture level. During the growth and drying process, raisins form a relatively stable moisture balance. Excess moisture on the surface after washing disrupts this balance. If moisture remains for a long time, it will not only make the raisins sticky but also provide a breeding ground for microorganisms such as mold and yeast. Through hot air circulation and low-temperature drying processes in drying equipment, surface and shallow moisture can be efficiently removed in a short time, allowing the moisture content of raisins to be precisely controlled within a range that is not conducive to microbial growth. This fundamentally eliminates the cause of spoilage and ensures that the raisins maintain a dry and crisp texture.

[0003] Existing drying equipment often relies on conveying components to achieve drying, which not only increases the size and cost of the equipment, but also makes it difficult to effectively prevent dust. Moreover, most drying equipment suffers from low drying efficiency due to poor airflow and uneven heating of materials in the drying chamber, and lacks basic temperature control, making it difficult to guarantee the quality of raisins. Therefore, we propose a drying device for raisin cleaning and production. Utility Model Content

[0004] The purpose of this utility model is to provide a drying device for the production of raisins, in order to solve the problems that existing drying devices often rely on conveying components to achieve drying, which not only increases the size and cost of the equipment, but also makes it difficult to effectively prevent dust. In addition, most drying devices have low drying efficiency due to poor airflow and uneven heating of materials in the drying chamber, and lack basic temperature control, making it difficult to ensure the quality of raisins.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drying device for raisin cleaning production, comprising a drying box, wherein a heating component, an airflow circulation component, and a material placement component are provided on the drying box, the heating component includes a heating box, two sets of heating boxes are provided and respectively arranged on the left and right sides of the drying box, and elongated heat dissipation slits are provided on both the left and right sides of the drying box, a heating tube is provided inside the heating box, the heating tube is fixed inside the heating box by a fixing block, two sets of fixing ears are fixedly installed on both sides of the surface of the heating box, and the heating box is installed on the outer wall of the drying box by bolts passing through the fixing ears.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. By setting up heating components, two sets of heating boxes are respectively located on the left and right outer walls of the drying chamber. With the long strip heat dissipation seam on the side wall of the drying chamber, the heat generated by the heating tube can be evenly diffused into the interior of the drying chamber. The material placement component adopts multiple sets of equally spaced material trays. Through the sliding cooperation of T-shaped sliders with T-shaped grooves on the inner wall of the drying chamber, the material can be conveniently picked up and placed and layered without the need for complex conveying components. This not only reduces the size of the equipment and the difficulty of production and maintenance, but also allows each layer of material to be evenly exposed to heat.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see the appendix Figure 1 - Appendix Figure 6 A drying device for raisin cleaning and production includes a drying chamber 1. The drying chamber 1 is equipped with a heating component 2, an airflow circulation component 3, and a material placement component 4. The heating component 2 includes a heating box 201. Two sets of heating boxes 201 are provided and are respectively located on the left and right sides of the drying chamber 1. Long strip-shaped heat dissipation slits 202 are opened on both sides of the drying chamber 1. Heating tubes 203 are provided inside the heating boxes 201. The heating tubes 203 are fixed inside the heating boxes 201 by fixing blocks 204. Two sets of fixing ears 205 are fixedly installed on both sides of the surface of the heating boxes 201. The heating boxes 201 are installed on the outer wall of the drying chamber 1 by bolts passing through the fixing ears 205. In this structure, the heating boxes 201 are fixed to the outer wall of the drying chamber 1 by the cooperation of the fixing ears 205 and bolts. This not only facilitates the later maintenance and replacement of the heating tubes 203, but also allows the heat generated by the heating tubes 203 to be evenly introduced into the interior of the drying chamber 1 through the long strip-shaped heat dissipation slits 202, avoiding local heat accumulation and ensuring that the raisins are heated evenly.

[0024] The drying oven 1 has a stable base 6 at the bottom, and a drying box 7 is fixedly installed at the bottom of the drying oven 1. The drying box 7 is filled with desiccant. The front of the drying oven 1 has a sealed door 5, and the sealed door 5 has a transparent observation window 8 and a display controller 9 fixedly installed. The top of the drying oven 1 is fixedly installed with a temperature sensor 10. The stable base 6 can improve the stability of the drying oven 1 when it is placed. The desiccant in the drying box 7 can help absorb the moisture in the drying oven 1 to enhance the drying effect, and can also absorb the moisture in the air entering the drying oven 1 from the outside. The sealed door 5 can reduce heat loss. The transparent observation window 8 makes it easy to check the drying progress in real time. The cooperation between the temperature sensor 10 and the display controller 9 can realize the accurate monitoring and control of the temperature inside the oven.

[0025] The material placement component 4 includes a fixed column 403 and a material tray 401. Multiple sets of material trays 401 are fixedly installed on the circumferential surface of the fixed column 403 at equal intervals. T-shaped sliders 402 are fixedly installed on both sides of the multiple sets of material trays 401. Multiple sets of T-shaped grooves 405 are opened on the inner walls of the left and right sides of the drying chamber 1. The material trays 401 are slidably connected to the T-shaped grooves 405 through the T-shaped sliders 402. Ventilation holes 404 are opened on the material trays 401. The front end of one set of material trays 401 is opened with a pull groove for pulling out the material placement component 4. Multiple sets of material trays 401 are installed at equal intervals on the circumferential surface of the fixed column 403, which can make full use of the internal space of the drying chamber 1. The sliding cooperation between the T-shaped sliders 402 and the T-shaped grooves 405 makes it convenient to pick up and put in the material placement component 4. The ventilation holes 404 facilitate the penetration of hot air. The pull groove design further reduces the difficulty for operators to pull out the material placement component 4.

[0026] Specifically, addressing the issues of large size, high cost, and uneven material heating caused by existing drying devices relying on conveying components, this device achieves improvements through optimized design of the heating component 2 and the material placement component 4: In the heating component 2, two sets of heating boxes 201 are respectively installed on the left and right outer walls of the drying chamber 1. Together with the elongated heat dissipation seams 202 on the side wall of the drying chamber 1, the heat generated by the heating tube 203 can be evenly diffused into the interior of the drying chamber 1. Furthermore, the heating tube 203 is stably fixed by the fixing block 204, preventing the components from shaking during heating and affecting heat output. The material placement component 4 uses multiple sets of equally spaced material trays 401, which are slidably connected to the T-shaped sliding grooves 405 on the inner wall of the drying chamber 1 through T-shaped sliders 402. This eliminates the need for complex conveying components, enabling convenient picking and placing of materials and layered placement. This reduces the size of the equipment, lowers production and maintenance costs, and ensures that each layer of material is evenly exposed to heat. At the same time, the vent holes 404 on the material trays 401 further improve heat penetration, effectively solving the problem of uneven material heating in traditional devices.

[0027] Please see the appendix Figure 1 - Appendix Figure 4The airflow circulation component 3 includes an exhaust fan 302. An air outlet 301 is provided on the top of the drying chamber 1. The exhaust fan 302 is located inside the air outlet 301. A dustproof mesh 303 is detachably installed at the top of the drying chamber 1 and at the air outlet 301. An air inlet 304 is provided at the bottom of the drying chamber 1, and a sealed dustproof mesh is installed inside the air inlet 304. The exhaust fan 302, the air outlet 301, and the air inlet 304 work together to form a stable airflow circulation, which accelerates the discharge of moisture from the drying chamber 1 to improve drying efficiency. The dustproof mesh 303 and the sealed dustproof mesh inside the air inlet 304 can effectively block external dust from entering the drying chamber 1 and prevent the raisins from being contaminated during the drying process.

[0028] Temperature sensor 10 is electrically connected to display controller 9, which is electrically connected to heating tube 203 and exhaust fan 302 respectively. Temperature sensor 10 transmits the temperature signal inside drying chamber 1 to display controller 9 in real time. Display controller 9 adjusts the heating power of heating tube 203 and the speed of exhaust fan 302 according to the signal to ensure that the temperature inside drying chamber 1 is stable within a suitable range for drying raisins and to ensure the quality of dried raisins.

[0029] Specifically, addressing the problems of poor airflow, low drying efficiency, poor dust prevention, and lack of basic temperature control in existing devices, this device achieves breakthroughs through the airflow circulation component 3 and other structural optimizations. In the airflow circulation component 3, the air outlet 301 at the top of the drying chamber 1, together with the exhaust fan 302 and the air inlet 304 at the bottom, forms a stable air circulation path, accelerating the removal of moisture during the drying process and significantly improving drying efficiency. Furthermore, the dustproof mesh plate 303 at the air outlet 301 and the sealed dustproof mesh inside the air inlet 304 effectively block external dust from entering, preventing material contamination. At the same time, the drying box 7 at the bottom of the drying chamber 1 can absorb moisture with the help of internal desiccant, improving the drying effect. The temperature sensor 10 inside the drying chamber 1 is electrically connected to the display controller 9 on the sealed chamber door 5, which can monitor and adjust the drying temperature in real time. Together with the display controller 9, it controls the heating tube 203 and the exhaust fan 302 to achieve precise temperature control, avoiding improper temperature from affecting the quality of raisins. The transparent observation window 8 on the sealed chamber door 5 also allows operators to easily check the drying progress in real time, further ensuring the drying effect.

[0030] Working principle of this utility model: This utility model is a drying device for raisin cleaning and production. When using this drying device for raisin cleaning and production, first open the sealed door 5 on the front side of the drying chamber 1. Through the pull groove at the front end of one set of material trays 401, pull out the material placement component 4 along the T-shaped sliding groove 405 on the inner wall of the drying chamber 1. Spread the cleaned raisins evenly in multiple sets of material trays 401 that are fixed at equal intervals on the fixing columns 403. Then push the material placement component 4 back into the drying chamber 1 through the cooperation of the T-shaped slider 402 and the T-shaped sliding groove 405 and close the sealed door 5. Then set the appropriate drying temperature through the display controller 9 on the sealed door 5. After starting the equipment, the heating tubes 203 in the two sets of heating boxes 201 installed on the left and right outer walls of the drying chamber 1 and fixed by the fixing blocks 204 start to heat up. The heat is evenly diffused into the interior of the drying chamber 1 through the long strip heat dissipation seam 202 on the side wall of the drying chamber 1. At the same time, the air outlet 30 on the top of the drying chamber 1 in the airflow circulation component 3... The exhaust fan 302 inside the drying chamber 1 starts, forming a stable air circulation path with the air inlet 304 at the bottom of the drying chamber 1, accelerating the discharge of moisture generated during the drying process. The dustproof mesh 303 at the air outlet 301 and the sealed dustproof mesh inside the air inlet 304 can prevent external dust from entering. During the drying process, the temperature sensor 10 at the top of the drying chamber 1 monitors the temperature inside the chamber in real time and transmits the signal to the display controller 9. If the temperature deviates from the set value, the display controller 9 will automatically adjust the heating power of the heating tube 203 and the speed of the exhaust fan 302 to achieve precise temperature control. The desiccant in the drying box 7 at the bottom of the drying chamber 1 helps to absorb moisture. The operator can also check the drying progress of the raisins in real time through the transparent observation window 8 on the sealed door 5. After drying is completed, the power of the equipment is turned off, the sealed door 5 is opened again, and the material placement component 4 is pulled out. The dried raisins can then be taken out from the material tray 401. The whole process does not require complicated conveying components and can ensure the uniformity of drying and the quality of the raisins. At this point, the entire process is complete.
