Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and in particular to a temperature-controlled areca nut processing dryer. Background Technology

[0002] Areca nut is the fruit of the areca palm, a plant in the palm family, and is an important traditional Chinese medicine from southern China. During the production and processing of areca nut, it needs to be dried to remove excess moisture and meet production requirements. The quality of the drying process directly affects the taste and texture of the areca nut.

[0003] Existing areca nut drying equipment often results in areca nuts piling up inside the device, reducing drying efficiency. Furthermore, the areca nuts remain stationary during drying, leading to uneven drying and significantly impacting their taste and texture. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the prior art by proposing an areca nut processing dryer that features temperature control, ensures uniform drying of areca nuts, and improves the drying efficiency of areca nuts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A temperature-controlled areca nut processing and drying machine, comprising:

[0007] shell;

[0008] A fixed cylinder, which is fixedly connected to the inside of the outer casing;

[0009] A rotating cylinder is rotatably connected to the inside of a fixed cylinder. The outside of the rotating cylinder is equipped with helical blades. The rotating cylinder drives the helical blades to rotate, so that the areca nuts move upward from the bottom of the fixed cylinder.

[0010] The lower guide plate is located at the bottom inside the outer casing and is funnel-shaped to allow the betel nuts to roll from the high point to the low point of the lower guide plate. Multiple air outlets are provided on the lower guide plate.

[0011] And heating wires, which are located at the bottom of the lower guide plate, to heat the air passing through the air outlet.

[0012] Furthermore, the top of the fixed cylinder is provided with a discharge port, and an upper guide plate is fixedly connected to the outside of the fixed cylinder. The upper guide plate is located below the discharge port and is umbrella-shaped. The bottom of the fixed cylinder is provided with a feed port, which is located above the lower guide plate.

[0013] Furthermore, a drive motor is installed on the outer casing, and the output shaft of the drive motor is connected to the rotating cylinder.

[0014] Furthermore, a fan is installed on the outer casing, an air guide tube is provided on the outer side of the outer casing, and multiple ventilation holes are provided at equal intervals around the outer side of the outer casing so that the air guide tube is connected to the bottom space of the lower guide plate. The air outlet of the fan is connected to the air guide tube, and multiple air inlets are provided at equal intervals around the middle of the rotating cylinder. The air inlets of the fan are connected to the rotating cylinder.

[0015] Furthermore, the outer side of the helical blade is in close contact with the inner wall of the fixed cylinder.

[0016] Furthermore, the top of the outer casing has an inlet with an upper sealing cover, and the bottom of the outer casing has an outlet that communicates with the internal space of the fixed cylinder with a lower sealing cover.

[0017] Furthermore, a temperature sensor is installed inside the casing to detect the internal temperature of the casing.

[0018] The beneficial effects of this utility model are as follows:

[0019] In this invention, the temperature-controlled areca nut processing and drying machine drives a spiral blade via a drive motor, causing the areca nuts to circulate up and down inside the shell. As the areca nuts fall, they fall along the umbrella-shaped upper guide plate to the top of the lower guide plate, and then roll down the funnel-shaped lower guide plate from the highest point. On the one hand, the rolling areca nuts facilitate the uniform heating and drying by hot air; on the other hand, the rolling of the areca nuts from the highest point of the lower guide plate increases the rolling time, thereby improving the drying effect.

[0020] The air inside the outer shell is circulated by a fan, which reduces heat loss. The hot air enters the inside of the fixed cylinder and dries the areca nuts that are moving upward inside the fixed cylinder, thereby further improving the drying effect of the areca nuts.

[0028] Reference Figure 1-2 A temperature-controlled areca nut drying machine is used in the drying process of areca nuts to improve drying efficiency and ensure uniform drying of areca nuts.

[0029] The temperature-controlled areca nut processing and drying machine includes an outer shell 1, a fixed cylinder 5, a rotating cylinder 6, a lower guide plate 8, and an electric heating wire 9;

[0030] An inlet is provided at the top of the outer shell 1, and an upper sealing cover 101 is provided at the inlet. By opening the upper sealing cover 101, areca nuts to be dried can be added into the interior of the outer shell 1 through the inlet.

[0031] A fixed cylinder 5 is fixedly connected to the inside of the outer shell 1. The top and bottom of the fixed cylinder 5 are respectively provided with a discharge port 501 and a feed port 502. A rotating cylinder 6 is rotatably connected to the inside of the fixed cylinder 5. A spiral blade 601 is provided on the outside of the rotating cylinder 6, with the outer side of the spiral blade 601 closely attached to the inner wall of the fixed cylinder 5. A drive motor 3 is installed on the outer shell 1, and the output shaft of the drive motor 3 is connected to the rotating cylinder 6. The drive motor 3 can drive the rotating cylinder 6 to rotate, thereby driving the spiral blade 601 to rotate, so that the areca nuts inside the outer shell 1 enter the fixed cylinder 5 through the feed port 502, then move upwards from the bottom of the fixed cylinder 5, and finally exit through the discharge port 501. This achieves a bottom-to-top circulating movement of the areca nuts inside the outer shell 1, improving the drying efficiency and uniformity of the areca nuts.

[0032] Furthermore, a funnel-shaped lower guide plate 8 is disposed at the bottom of the inner casing 1, and the feed inlet 502 is located above the lower guide plate 8. An upper guide plate 7 is fixedly connected to the outside of the fixed cylinder 5. The upper guide plate 7 is located below the discharge outlet 501 and is umbrella-shaped. The areca nuts discharged from the discharge outlet 501 will roll outward along the umbrella-shaped upper guide plate 7 and finally fall to the high point of the lower guide plate 8. The funnel-shaped lower guide plate 8 allows the areca nuts to roll from the high point of the lower guide plate 8 to the low point.

[0033] The heating wire 9 is located at the bottom of the lower guide plate 8. The lower guide plate 8 has multiple air outlets 801. When the heating wire 9 is energized, it can heat the air at the bottom of the lower guide plate 8. The hot air is sprayed out through the air outlets 801 to dry and heat the areca nuts that roll from the top to the bottom of the lower guide plate 8. Since the areca nuts circulate up and down inside the outer shell 1 and roll down on the lower guide plate 8, the rolling time of the areca nuts on the lower guide plate 8 is increased, thereby allowing the areca nuts to be heated and dried evenly, improving the drying effect.

[0034] Furthermore, a temperature sensor is installed inside the outer casing 1. The temperature sensor can detect the internal temperature of the outer casing 1 in real time, helping the operator to obtain the internal temperature of the outer casing 1 and adjust the power of the heating wire 9 accordingly, so as to maintain the internal temperature of the outer casing 1 at the optimal temperature for drying areca nuts. The temperature detection principle, installation method of the temperature sensor, and power adjustment technology of the heating wire 9 are all existing technologies and will not be described in detail here.

[0035] A fan 4 is mounted on the outer casing 1, and an air guide duct 2 is provided on the outer side of the outer casing 1. Multiple ventilation holes 103 are provided at equal intervals around the outer side of the outer casing 1 to connect the air guide duct 2 with the bottom space of the lower guide plate 8. The air outlet of the fan 4 is connected to the air guide duct 2. The fan 4 can pump air into the air guide duct 2, and then the air enters the bottom space of the lower guide plate 8 evenly through the ventilation holes 103 and is heated by the heating wire 9.

[0036] Multiple air inlets 602 are evenly spaced around the center of the rotating cylinder 6, and the air inlet of the fan 4 is connected to the rotating cylinder 6. After the hot air heats the areca nuts on the lower guide plate 8, it enters the interior of the fixed cylinder 5 through the discharge port 501 and the feed port 502. Ultimately, the upper air in the fixed cylinder 5 flows downward and the lower air flows upward, entering the rotating cylinder 6 through the air inlets 602 and being drawn by the fan 4, thus circulating the hot air and reducing heat loss. Furthermore, as the hot air flows inside the fixed cylinder 5, it dries the areca nuts moving upward inside the fixed cylinder 5, further improving the drying effect.

[0037] The bottom of the outer shell 1 has an outlet that communicates with the internal space of the fixed cylinder 5, and a lower sealing cover 102 is provided at the outlet. After the areca nuts are dried, the lower sealing cover 102 can be opened to allow the dried areca nuts to be discharged through the outlet.

[0038] The working principle of the temperature-controlled areca nut processing and drying machine is as follows: Open the upper sealing cover 101, put the areca nuts to be dried into the inside of the outer shell 1, and then close the upper sealing cover 101. Drive the rotating drum 6 to rotate through the drive motor 3. The rotating drum 6 drives the spiral blades 601 to move, thereby driving the areca nuts from the feed port 502 into the fixed cylinder 5. They are transported from bottom to top inside the fixed cylinder 5 and finally discharged through the discharge port 501. The discharged areca nuts will fall along the umbrella-shaped upper guide plate 7, thus falling to the high point of the lower guide plate 8, and rolling down from the highest point along the funnel-shaped lower guide plate 8.

[0039] Simultaneously, air is pumped into the air duct 2 by the fan 4, and then the air enters the bottom space of the lower guide plate 8 evenly through the ventilation holes 103. It is heated by the heating wire 9, and the hot air is ejected through the air outlet 801, evenly drying the areca nuts rolling down the lower guide plate 8. The hot air then enters the interior of the fixed cylinder 5 through the discharge port 501 and the inlet 502. Finally, the upper air in the fixed cylinder 5 flows downwards, and the lower air flows upwards, entering the rotating cylinder 6 through the air inlet 602 and being drawn by the fan 4, thus circulating the hot air and reducing heat loss. Furthermore, as the hot air flows inside the fixed cylinder 5, it dries the areca nuts moving upwards inside the fixed cylinder 5, further improving the drying effect.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
