Description

Technical Field

[0001] This utility model relates to the technical field of tea seed processing equipment, and in particular to a uniform tea seed dryer. Background Technology

[0002] In the camellia oil industry, tea seeds are used as the raw material for extracting high-quality tea oil. The drying process after harvesting is a crucial step affecting the oil yield and quality. Tea seeds have a high moisture content, and if they are not dried in a timely and effective manner, they are prone to mold and rancidity, leading to an increase in the acid value of the oil and a darkening of its color, which seriously affects the quality and storage stability of the tea oil.

[0003] Currently, tea seed drying methods mainly include natural sun-drying and traditional drying equipment. Natural sun-drying is low-cost but heavily reliant on weather conditions, has a long drying cycle, and is susceptible to contamination from dust, rain, and pests. It also results in uneven drying, with the surface easily drying while the interior remains moist, making it difficult to achieve the required moisture content for oil extraction (typically 8%-12%). Furthermore, the lack of sufficient drying space in large-scale planting areas hinders industrial development. Traditional drying equipment often uses hot air furnaces or electric heating, employing fixed ovens or drums for drying. However, these devices generally suffer from uneven hot air distribution, leading to localized overheating or underheating during the drying process. This results in some seeds scorching while others remain moist, leading to poor drying uniformity. Insufficient material agitation and seed accumulation also reduce heat transfer efficiency, making it difficult to effectively remove internal moisture.

[0004] Therefore, it is necessary to design a tea seed uniform drying machine to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the shortcomings of uneven hot air distribution and insufficient material agitation, this utility model provides a uniform tea seed dryer.

[0006] Technical Solution: A uniform tea seed dryer includes an outer shell, a baffle, a feeding frame, an air supply pipe, an air pump, a heating pipe, a connecting pipe, an auger, a motor, a rotating shaft, and bevel gears. The inner side of the outer shell is divided into three areas: left, middle, and right. The top and bottom of the three areas are connected. A baffle is slidably connected to the middle of the rear side of the outer shell. A feeding frame is fixedly connected to the top of the outer shell. An air supply pipe is fixedly connected to the front of the lower part of the outer shell. An air pump is installed on the upper part of the air supply pipe. A cavity is provided in the lower part of the outer shell. A heating pipe is provided in the lower part of the cavity. Connecting pipes are fixedly connected to both the left and right sides of the outer shell. The lower ends of the two connecting pipes are connected to the cavity. An auger is rotatably connected to the middle of the outer shell. A motor is fixedly connected to the front of the lower part of the outer shell. A rotating shaft is fixedly connected to the output shaft at the rear end of the motor. Bevel gears are fixedly connected to the rear of the rotating shaft and the lower part of the auger. The two bevel gears mesh.

[0007] Preferably, it also includes inclined plates, with multiple inclined plates fixedly connected to the left and right sides of the two areas inside the outer casing.

[0008] Preferably, the device also includes a vent plate, with the left and right sides of the inner side of the outer shell fixedly connected to the cavity.

[0009] Preferably, the cavity also includes a protective shell, which is fixedly connected to the top of the cavity, and two bevel gears are located inside the protective shell, with the rotating shaft rotatably connected to the protective shell.

[0010] Preferably, the device also includes a mounting frame, a material extraction pipe, a partition, a pull rod, and a filter screen. The mounting frame is fixedly connected between the left side of the material discharge frame and the air supply pipe. Two material extraction pipes are fixedly connected between the rear side of the mounting frame and the outer casing. A partition is slidably connected to the front side of the mounting frame. A pull rod is fixedly connected to the top of the partition. A filter screen is provided at the bottom of the mounting frame.

[0011] Preferably, the device also includes a temperature controller and a temperature sensor. The temperature controller is fixedly connected to the front right side of the housing, and the temperature sensor is fixedly connected to the top left side of the housing. Both the heating element and the temperature sensor are electrically connected to the temperature controller.

[0012] The beneficial effects of this utility model are: 1. This utility model uses a motor to drive the rotating shaft and bevel gear transmission to drive the auger to rotate, so that the tea seeds slowly rise and turn in the middle of the shell, which significantly avoids the accumulation of tea seeds. Then, with the cooperation of heating pipe, connecting pipe and air pump, a stable hot air circulation from bottom to top is formed, which effectively prevents local overheating or uneven drying, and improves the uniformity of drying and processing efficiency.

[0013] 2. This utility model monitors the temperature in real time through a temperature measuring head, and adjusts the power and start / stop of the heating tube with a temperature controller to keep the drying process within a suitable temperature range, avoiding the destruction of tea seed nutrients or scorching caused by high temperature, thus ensuring the quality and stability of the dried tea seeds.

[0014] 3. This utility model, through the cooperation of the mounting frame and the filter screen, automatically intercepts small impurities and broken leaves when tea seeds enter. Furthermore, the design of opening and closing the partition through the pull rod makes the filter screen cleaning operation simple and quick, effectively improving the purity of raw materials and the efficiency of equipment maintenance.

[0015] 4. This utility model extends the contact path by arranging the inclined plates, achieving layer-by-layer drying and forming a stable hot air circulation from bottom to top, effectively preventing local overheating or uneven drying. Attached Figure Description

The inner side of the shell 1 is divided into three areas: left, middle, and right. The top and bottom of the three areas are connected. The baffle 101 is slidably connected to the middle of the rear side of the shell 1. The feeding frame 2 is fixedly connected to the top of the shell 1. The air supply pipe 3 is fixedly connected to the front of the lower part of the shell 1. The air pump 4 is installed on the upper part of the air supply pipe 3. The lower part of the shell 1 has a cavity. The heating pipe 5 is installed in the lower part of the cavity. The connecting pipes 6 are fixedly connected to both the left and right sides of the shell 1. The lower ends of the two connecting pipes 6 are connected to the cavity. The auger 11 is rotatably connected to the middle of the shell 1. The motor 9 is fixedly connected to the front of the lower part of the shell 1 by bolts. The output shaft of the rear end of the motor 9 is fixedly connected to the rotating shaft 10. The rear part of the rotating shaft 10 and the lower part of the auger 11 are both fixedly connected to bevel gears 12. The two bevel gears 12 mesh.

[0026] like Figure 3As shown, it also includes inclined plates 7, and multiple inclined plates 7 are fixedly connected to the left and right sides of the two regions inside the outer shell 1.

[0027] like Figure 4 As shown, it also includes a vent plate 8, and the vent plates 8 are fixedly connected to the cavity on the left and right sides of the inner side of the outer shell 1.

[0028] like Figure 3 and Figure 5 As shown, it also includes a protective shell 13. The protective shell 13 is fixedly connected to the top of the inner side of the cavity. Two bevel gears 12 are located inside the protective shell 13, and the rotating shaft 10 is rotatably connected to the protective shell 13.

[0029] like Figure 1 and Figure 6 As shown, it also includes a mounting frame 14, a material extraction pipe 15, a partition 16, a pull rod 17, and a filter screen 1701. The mounting frame 14 is fixedly connected between the left side of the material feeding frame 2 and the air supply pipe 3. Two material extraction pipes 15 are fixedly connected between the rear side of the mounting frame 14 and the outer shell 1 by bolts. The partition 16 is slidably connected to the front side of the mounting frame 14. The pull rod 17 is fixedly connected to the top of the partition 16. The filter screen 1701 is provided at the bottom of the mounting frame 14.

[0030] like Figure 1 and Figure 8 As shown, it also includes a temperature controller 18 and a temperature sensor 19. The temperature controller 18 is fixedly connected to the front right side of the outer casing 1 by bolts, and the temperature sensor 19 is fixedly connected to the top left side of the outer casing 1 by bolts. The heating tube 5 and the temperature sensor 19 are both electrically connected to the temperature controller 18.

[0031] When this device is needed to uniformly dry tea seeds, first start the air pump 4 and motor 9, then pour the tea seeds to be dried into the feeding frame 2 at the top of the outer shell 1. The tea seeds enter the interior of the outer shell 1 under the action of gravity. During the falling process, some small impurities or broken tea leaves will pass through the suction pipe 15 between the feeding frame 2 and the air supply pipe 3, and be intercepted by the filter screen 1701 at the bottom of the mounting frame 14. The operator can open and close the partition 16 on the front side of the mounting frame 14 by pulling the lever 17, which makes it easy to clean the small impurities or broken tea leaves intercepted on the filter screen 1701.

[0032] After the tea seeds enter the outer shell 1, they first enter the middle of the inner side of the outer shell 1. The output shaft of the motor 9 drives the rotating shaft 10 to rotate, and the bevel gear 12 at the rear of the rotating shaft 10 rotates accordingly and meshes with another bevel gear 12 fixed at the lower part of the auger 11, thereby driving the auger 11 to rotate in the middle of the outer shell 1. The rotation of the auger 11 not only pushes the tea seeds to move slowly upward, but also continuously turns the tea seeds. After the tea seeds move upward, they fall into the left and right areas of the inner side of the outer shell 1 from the top. The inclined plates 7 on both sides guide the tea seeds to slide slowly down under the action of gravity and enter the middle of the inner side of the outer shell 1 again for circulation, effectively preventing accumulation and improving drying uniformity. The two bevel gears 12 are sealed in the protective shell 13 to prevent dust from entering and causing wear. At the same time, the rotating shaft 10 and the protective shell 13 are rotatably connected to ensure smooth and reliable transmission.

[0033] At the same time, the air pump 4 starts, sending outside air into the cavity at the bottom of the outer shell 1 through the air supply pipe 3. The cavity is equipped with a heating pipe 5 to heat the incoming air, forming a uniform hot air. The heated hot air flows upward through the ventilation plate 8 between the left and right areas of the outer shell 1 and the cavity. The hot air also flows into the left and right sides of the inner side of the outer shell 1 through the connecting pipes 6 on both sides, balancing the airflow pressure on the left and right sides of the outer shell 1 and ensuring that the hot air is distributed symmetrically and evenly. The hot air passes through the gap between the inclined plates 7 and comes into full contact with the tea seeds distributed on the inclined plates 7, taking away the moisture on their surface and inside. The inclined plates 7 are arranged at an angle, which can extend the contact path between the hot air and the tea seeds and guide the tea seeds to slowly slide down under the action of gravity, achieving layer-by-layer drying and ensuring uniform heating. The hot air continues to absorb moisture during the upward process and finally exits from the feeding frame 2 through the connecting ports of the three areas at the top of the outer shell 1, forming a stable hot air circulation from bottom to top, effectively avoiding local overheating or cold spots.

[0034] To achieve precise temperature control, the temperature controller 18 is activated. The temperature sensor 19 on the top left of the outer casing 1 monitors the internal temperature in real time and feeds the signal back to the temperature controller 18. The temperature controller 18 adjusts the start / stop or power of the heating tube 5 according to the preset temperature range to ensure that the drying process is carried out at a suitable temperature, avoiding damage to the nutrients of the tea seeds or scorching due to high temperature. After drying is completed, the heating tube 5 is turned off, the sliding baffle 101 is opened, and the tea seeds are discharged and collected for subsequent oil pressing. After collection is completed, the motor 9 and the temperature controller 18 are turned off, and then the baffle 101 is reset.
