Abstract
Description
Technical Field
[0001] This utility model relates to the field of drying equipment technology, and in particular to a lotus seed drying device. Background Technology
[0002] Lotus seeds are the dried, mature seeds of the lotus plant (Nelumbo nucifera), a member of the Nymphaeaceae family, and are widely distributed throughout China. Lotus seeds have the effects of tonifying the spleen and stopping diarrhea, stopping leukorrhea, benefiting the kidneys and astringing essence, and nourishing the heart and calming the mind. They are often used to treat symptoms such as spleen deficiency diarrhea, leukorrhea, seminal emission, palpitations, and insomnia. Most current lotus seed drying devices use tower drying, which causes lotus seeds to easily pile up and hinders drying. To address this, a lotus seed drying device is proposed that can improve drying efficiency and simultaneously sort the lotus seeds for further processing.

A long frame is fixed to the left circumferential outer wall of the drying cylinder, and a base is fixed to the upper outer wall of the long frame. A first motor is fixed to the upper outer wall of the base. The drying device in the aforementioned document has the following shortcomings: The device uses a tower structure, which can cause lotus seeds to accumulate at the bottom of the device, and the effect of stirring the lotus seeds to accelerate the drying process may not be very good.

[0029] Example 1
[0030] A lotus seed drying device, such as Figures 1-6 As shown, the device includes a drying device body 1, with a discharge port 5 at the front end and a feed pipe 3 above it. A drying assembly is located inside the drying device body 1, and a screening assembly is located below the drying assembly. The drying device also includes a control module and a temperature sensor. The drying assembly includes a drying seat 13, which is an annular structure. The drying seat 13 is mounted inside the drying device body 1 via a bracket, and a fan-shaped discharge hole is located at the bottom of the drying seat 13. A hot air blower 15 is installed on one side of the drying seat 13 and is electrically connected to the control module.
[0031] like Figure 6 As shown, the drying assembly also includes heating tubes 17, and several heating tubes 17 are arranged around the inside of the drying base 13; an air inlet pipe 4 is arranged on one side of the main body 1 of the drying device, and the air inlet pipe 4 is connected to the hot air blower 15.
[0032] Lotus seeds are placed on the drying rack 13. The hot air blower 15 is driven by the control module to generate hot air. The hot air is blown onto the lotus seeds through the heating tube 17 to dry and heat them. The temperature inside the device is detected by the temperature sensor. The control module controls the power of the hot air blower 15 according to the temperature data detected by the temperature sensor, thereby achieving constant temperature drying of the lotus seeds.
[0033] To solve the problem of lotus seeds sticking together during drying; such as Figure 3 , Figure 4 , Figure 6 As shown, the drying assembly also includes a second motor 14, which is mounted on the drying base 13 via a bracket and is electrically connected to the control module; a stirring rod 16 is installed at the output end of the second motor 14.
[0034] The control module drives motor 14 to rotate stirring rod 16, which stirs the lotus seeds in drying seat 13 to prevent them from sticking together during drying and affecting their quality.
[0035] To further address the issue of lotus seeds being sticky; such as... Figure 3 , Figure 6 As shown, the drying assembly also includes an arc-shaped plate 18, and several arc-shaped plates 18 are provided. The arc-shaped plates 18 are installed on the drying base 13. The bottom of the stirring rod 16 is provided with several grooves, which are adapted to the arc-shaped plates 18.
[0036] The lotus seeds can be separated by setting the arc plate 18, making it easier to stir the lotus seeds with the stirring rod 16.
[0037] To solve the problem of lotus seed selection; such as Figure 3 , Figure 5 As shown, the screening component includes a support member 9, which is installed inside the main body 1 of the drying device. A gear 10 is rotatably mounted on the support member 9. The gear 10 has several discharge holes, and the discharge holes on both sides of the gear 10 are of different sizes.

The motor 11 is installed inside the main body 1 of the drying device through a bracket. The motor 11 is electrically connected to the control module. A gear 12 is installed on the motor 11, and the gear 12 meshes with the gear 1.
[0039] The control module drives motor 11 to rotate, which in turn drives gear 12 to rotate. By positioning the smaller discharge hole on gear 12 at the bottom of the fan-shaped discharge port on the drying seat 13, the lotus seeds are moved out of the drying seat 13. Gear 12 is rotated again to move the larger discharge port to the discharge port position of the drying seat 13, so that the larger lotus seeds are removed from the device. This achieves the size screening of the lotus seeds, which is convenient for the next step of processing.
[0040] like Figure 2 , Figure 4 As shown, the drying device also includes a discharge trough 6, which is installed on the main body 1 of the drying device. The discharge trough 6 is located below the discharge port of the drying seat 13. An inclined surface is provided inside the discharge trough 6, and the front end of the discharge trough 6 is connected to the discharge port 5.

The temperature sensor detects the temperature conditions inside the device and controls the temperature of the hot air blower 15 through the control module. After the lotus seeds are dried, the control module drives the screening component to screen the lotus seeds. The screened lotus seeds are discharged from the device through the discharge chute 6 and the discharge port 5. Then the control module drives the first motor 11 to rotate to screen the lotus seeds a second time.
