Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of preservative production equipment, and specifically relates to a drying device for the production of pastry preservatives. Background Technology
[0002] Pastry preservatives are substances used to extend the shelf life of pastries and maintain their quality and taste. Among them, drying equipment for pastry preservative production is used to dry the raw materials or semi-finished products in the production process of pastry preservatives. Drying equipment for pastry preservative production includes various types such as chamber type, fluidized bed, and spray type. It consists of heating, ventilation, material conveying and control system. It uses hot air circulation to evaporate the moisture in the material, which has the characteristics of improving product quality, production efficiency and energy saving and environmental protection.
[0003] Currently, in commercially available box-type dryers, the preservative materials are in a relatively static state. As hot air flows, different parts of the material experience varying degrees of contact with the hot air, resulting in uneven drying. For example, materials closer to the heating source and vents may dry faster, while materials further away dry more slowly, affecting product consistency and quality stability. Furthermore, the stationary nature of the materials slows the diffusion of internal moisture to the surface. Simultaneously, the dry layer that forms on the surface during drying hinders further evaporation of internal moisture, extending the overall drying time. This not only reduces production efficiency but also increases energy costs. Utility Model Content
[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a drying device for the production of pastry preservatives, so as to solve the problem that the preservative material in the chamber dryer is in a relatively static state, and the hot air will cause different parts of the material to have different degrees of contact with the hot air during the flow process, resulting in uneven drying.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] A drying device for producing pastry preservatives includes a drying chamber with a hinged closed door on one side. A control panel is installed on the side of the drying chamber near the closed door. A heating plate is installed on one side inside the drying chamber. A movable tray is slidably connected to the bottom of the drying chamber. A material placement box is placed on top of the movable tray. Clamping components are symmetrically installed on top of the movable tray. A lifting seat is provided inside the drying chamber. An agitation component is installed at the bottom of the lifting seat. A lifting component is installed on top of the drying chamber.
[0007] The agitation assembly includes a second drive motor, a first synchronous pulley, a second synchronous pulley, a synchronous belt, a rotating rod, a mounting base, and agitating rollers. The second drive motor is mounted on the top of the lifting base. The output end of the second drive motor passes through the lifting base and is fixedly connected to the first synchronous pulley. The second synchronous pulley is rotatably connected to the center of the bottom of the lifting base via a bearing. A synchronous belt is installed between the first and second synchronous pulleys. A rotating rod is fixedly connected to the center of the bottom of the second synchronous pulley. The mounting base is threadedly connected to the bottom of the rotating rod. Agitating rollers are symmetrically fixedly connected to the outer wall of the mounting base via a ring-shaped array. This allows the preservative material to be continuously turned over during the drying process, ensuring that all parts of the material are fully in contact with the hot air, avoiding local overheating or overdrying, thus ensuring uniform drying, improving product quality consistency, and making it easier for moisture inside the material to migrate to the surface, accelerating the evaporation rate.
[0008] As a preferred technical solution, the lifting assembly includes a motor frame, a first drive motor, a drive gear, a rotating column, a driven gear, a threaded column, a limit block, and a threaded hole. A rotating column is embedded and rotatably connected to the top of the drying chamber. A driven gear is fixedly sleeved on the outer wall of the rotating column. The motor frame is fixedly connected to the top of the drying chamber, and the first drive motor is mounted on the top of the motor frame. The drive gear is rotatably connected to the top of the drying chamber. The output end of the first drive motor is fixedly connected to the drive gear, and the drive gear and driven gear mesh with each other. A threaded hole is opened on the top of the rotating column, and a threaded column is threadedly connected inside the threaded hole. The bottom of the threaded column is rotatably connected to the lifting seat, and a limit block is fixedly connected to the top of the threaded column. This allows for precise control of the drying degree of material layers at different heights, ensuring uniform agitation and improving the overall drying effect. Furthermore, raising the agitator allows for more comprehensive cleaning of the dryer's interior and the agitator, preventing material residue from contaminating the next batch of products and ensuring product quality and equipment hygiene.
[0009] As a preferred technical solution, a limiting tube is symmetrically fixedly connected to the top of the drying chamber, and a limiting column is symmetrically fixedly connected to the top of the lifting seat. The limiting column and the limiting tube are slidably connected, and the limiting column slides inside the limiting tube, providing a precise guiding effect for the lifting seat. This ensures that the lifting seat can rise and fall smoothly along the predetermined vertical direction, avoiding shaking, deviation, or tilting. This ensures that the agitation components and other parts connected to the lifting seat can accurately reach the set position, achieving effective agitation and processing of materials at different heights.
[0010] As a preferred technical solution, sliding blocks are symmetrically fixedly connected to the bottom of the drying chamber, and sliding grooves are symmetrically opened on the bottom of the movable tray. The sliding blocks and sliding grooves are slidably connected, which can be easily pulled out and pushed in from the chamber dryer. This makes it convenient for operators to place the pastry preservative materials to be dried on the tray and to remove the materials after drying, which greatly saves time and manpower and improves production efficiency.
[0011] As a preferred technical solution, the clamping assembly includes a fixed plate, an adjusting screw, and a clamping plate. The fixed plate is symmetrically fixedly connected to the top of the movable tray. The adjusting screw is threadedly connected to one side of the fixed plate. One end of the adjusting screw is rotatably connected to the clamping plate, and the other end of the clamping plate is in contact with the material placement box. This allows the material placement box to be fixed in a specific position inside the dryer, preventing the material placement box from moving or shaking due to factors such as fan blowing or equipment vibration during the drying process. This helps to ensure the relative position stability of the material inside the dryer, allowing the material to receive the effect of hot air evenly, thereby improving the consistency and stability of the drying effect.
[0012] As a preferred technical solution, an anti-slip pad is glued to one side of the clamping plate. The surface of the anti-slip pad has anti-slip protrusions and the anti-slip pad is made of soft rubber. It can hold the friction between the clamping plate and the material placement box, effectively preventing the material placement box from sliding or shifting on the clamping plate, ensuring that the material placement box always stays in the correct position, and ensuring the stability and safety of the drying process.
[0013] As a preferred technical solution, a centrifugal fan is installed on one side of the drying chamber, and a ventilation pipe is fixedly connected to the top of the drying chamber, which provides good air circulation, can accelerate the heat transfer process, and allow hot air to continuously exchange heat with the surface of the material, so as to remove the moisture evaporated from the material in time, effectively shorten the drying time, improve the drying efficiency, and increase the production capacity.
[0014] In summary, the present invention has the following main advantages:
[0015] First, in this utility model, the preservative is placed inside the material placement box, and then the material placement box is placed on the moving tray. Through the lifting component, the rotating rod is controlled to descend into the material placement box. At the same time, the second drive motor is started to control the first synchronous wheel to rotate. The first synchronous wheel drives the second synchronous wheel to rotate through the synchronous belt, thereby causing the rotating rod to drive the mounting base and the stirring roller to rotate. This allows the preservative material to be continuously turned over during the drying process, so that all parts can fully contact the hot air, avoiding local overheating or overdrying, thus ensuring the uniformity of drying, improving the consistency of product quality, and making it easier for the moisture inside the material to migrate to the surface, thus accelerating the evaporation rate of moisture.
[0016] Secondly, in this utility model, the preservative is placed inside the material placement box, and then the material placement box is placed on the moving tray. The first drive motor is started, and the drive gear is controlled to rotate. The drive gear drives the driven gear to rotate, thereby causing the rotating column to rotate. This causes the threaded column and the threaded hole to rotate, thereby controlling the threaded column to drive the lifting seat to descend. This enables precise control of the drying degree of material layers at different heights, ensuring uniform stirring effect and improving the overall drying effect. Moreover, raising the stirring roller allows for more comprehensive cleaning of the inside of the dryer and the stirring roller, preventing material residue from contaminating the next batch of products and ensuring product quality and equipment hygiene.
