Description

Technical Field

[0001] This invention relates to the field of agricultural product deep processing technology, specifically to a three-dimensional lotus seed production line. Background Technology

[0002] Lotus seeds are the seeds of the lotus plant (Nelumbo nucifera), a member of the Nelumbo family. Harvesting begins in June each year when the fruit matures. The lotus receptacle is then removed, the fruit is extracted, the pericarp is removed, and the seeds are dried to obtain red lotus seeds. After further processing and peeling, red lotus seeds become white lotus seeds. Lotus seeds are also categorized into cored and uncored varieties. Additionally, byproducts from lotus seed processing, such as lotus seed fragments, lotus cores, peeling ash, and broken lotus seeds, can be sold as byproducts.

[0003] The differences between white lotus seeds and red lotus seeds generally lie in their efficacy, source, nutritional value, suitable population, and contraindications.

[0004] 1. Efficacy: White lotus seeds tend to improve spleen and stomach function, digestive system, and diarrhea, and are often used to treat patients with chronic indigestion, diarrhea, and loss of appetite. Red lotus seeds, compared to white lotus seeds, are more focused on nourishing blood and essence, and are especially suitable for women with severe blood deficiency, insomnia, menstrual disorders, and other symptoms.

[0005] 2. Source: White lotus seeds are made from red lotus seeds after the skin has been removed, while red lotus seeds are the product of dried fruit.

[0006] 3. Nutritional Value: White lotus seeds are rich in protein, vitamin B1, vitamin B2, and other nutrients, which aid in gastrointestinal digestion. Red lotus seeds, on the other hand, contain abundant dietary fiber, trace elements, and other nutrients, which help regulate menstruation and replenish blood.

[0007] 4. Suitable groups: White lotus seeds are generally suitable for people with poor digestive function and irregular eating habits. Red lotus seeds are more suitable for women who need to regulate menstruation and nourish blood.

[0008] 5. Contraindications: White lotus seeds replenish qi, therefore they are not suitable for people with yin deficiency and excessive internal heat, damp heat, or excess heat. Red lotus seeds replenish blood, therefore they are not suitable for people with weak constitutions or high blood pressure.

[0009] Existing lotus seed production lines can produce red lotus seeds, cored red lotus seeds, white lotus seeds, and red and white lotus seeds with outer edges, among others. These lines require a large amount of equipment and, if laid out horizontally, would occupy a significant amount of space, resulting in high investment costs. Furthermore, the processing generates substantial amounts of dust and noise (e.g., shelling, grading, core removal, grinding, and sieving). Manual sorting requires a clean environment, away from noise and dust. Summary of the Invention

[0050] S1: Collect dried lotus shells (specifically Xianglian lotus, with a diameter of 9.0-14.0mm), and remove impurities using a vibrating screen. Qualified products are sent to silo one for temporary storage and then to step S2.

[0051] S2: Grade the qualified products by grading sieve and divide the lotus seeds into 10 grades according to size. Then send them to the shelling device of the corresponding diameter for shelling. The lotus seeds from all the shelling devices are collected by the collection and conveying device and then sent to the air separation device to remove the lotus shells. The air-separated lotus seeds are sent to step S3. The air-separated lotus shells are color sorted by the fifth channel color sorter to separate the lotus shells and lotus seeds. The lotus seeds (the number of lotus seeds is very small, so manual screening is sufficient and there is no need to screen them, which will not damage the skin) are sent to the manual selection device for manual selection to obtain the red lotus seed product.

[0052] S3: Use multiple color sorters (five color sorters) to sort lotus seeds. Select lotus seeds that are shell-free, light-colored, free of scratches and mold, as red lotus seeds and send them to step S4; select lotus seeds with shells and send them to step S2; select dark-colored lotus seeds or lotus seeds with scratches as semi-finished products and send them to step S5.

[0053] Specifically, step S3 includes the following steps:

[0054] S301: The lotus seeds after air separation are sorted by a color sorter in the first channel to obtain lotus seeds with shells and lotus seeds without shells. The lotus seeds without shells are sent to step S302, and the lotus seeds with shells are sent to step S306.

[0055] S302: The shell-less lotus seeds are sorted by a second-channel color sorter to obtain dark-colored lotus seeds (commonly known as old lotus seeds) and light-colored lotus seeds (commonly known as non-old lotus seeds). The light-colored lotus seeds are sent to step S303, and the dark-colored lotus seeds are sent to step S5 after sieving.

[0056] S303: The light-colored lotus seeds are sorted by a third-channel color sorter to obtain lotus seeds with scratches (commonly known as flower seeds) and lotus seeds without scratches (commonly known as non-flower seeds). Lotus seeds without scratches are sent to step S304, and lotus seeds with scratches are sent to step S5 after sieving.

[0057] S304: A vibrating screen is used to remove waste material, followed by color sorting using a first tracked color sorter to obtain moldy lotus seeds and non-moldy lotus seeds. The non-moldy lotus seeds are sent to step S4, while the moldy lotus seeds are treated as waste. In this step, to reduce damage to the lotus seed skin by the equipment, screening is performed before color sorting. All other processes use color sorting followed by screening.

[0058] S305: Use a fourth-channel color sorter to color sort the lotus seeds in their shells, separating them into kernel seeds and non-kernel seeds. Kernel seeds are sent to step S302, and non-kernel seeds are sent to step S2.

[0059] S4: Red lotus seeds are manually selected at the manual selection device to obtain red lotus seed products.

[0060] S5: The semi-finished product is graded by grading screen 2, and the lotus seeds are divided into 3 grades according to size. They are then sent to the corresponding diameter core removal device for core removal. All the lotus seeds from the core removal device are collected by the collection conveyor device 2, and the cores are removed by the rolling screen to obtain cored red lotus seeds. They are sent to the material silo 2 for temporary storage and sent to step S6 and / or S7 as needed. The obtained lotus hearts are screened by vibrating screen 6. The selected lotus seeds are then manually selected at the manual selection device to obtain the cored red lotus seed product.

[0061] S6: The cored red lotus seeds are sieved (specifically, vibrating screen four) and manually selected at the manual selection device to obtain the cored red lotus seed product.

[0062] S7: The cored red lotus seeds are graded using a three-stage grading sieve, and divided into three grades according to size. These grades are then sent to a primary grinding machine of the corresponding diameter for primary grinding, and then to a secondary grinding machine of the corresponding diameter for secondary grinding. All lotus seeds from the secondary grinding are collected by a three-stage conveyor and sent to step S8; the red ash from the primary grinding and the white ash from the secondary grinding are recovered. Both primary and secondary grinding use reciprocating grinding machines. The primary grinding time is 80-150 seconds, and the secondary grinding time is 40-80 seconds.

[0063] S8: Color sorting is performed on the peeled lotus seeds to obtain cleaned lotus seeds and unpolished lotus seeds. The cleaned lotus seeds are then sieved and manually selected to obtain white lotus seed products.

[0064] Step S8 specifically includes:

[0065] S801: Color sorting is performed by the sixth channel color sorter to obtain cleaned lotus seeds and uncleaned lotus seeds respectively. Cleaned lotus seeds are sent to step S802, and uncleaned lotus seeds are sent to step S901.

[0066] S802: The white lotus seed product is obtained by grinding the lotus seeds, sieving (using a vibrating screen five), and manually selecting them at the manual selection device.

[0067] S9: Unpeeled lotus seeds are sent to a three-stage peeling machine for three-stage peeling. Peeled lotus seeds are then sent to step S8.

[0068] Step S9 specifically includes:

[0069] S901: Unpeeled lotus seeds are sent to the third peeling machine for three peelings. After peeling, the lotus seeds are sent to step S902 and the white ash from the three peelings is collected. The three peelings take 30-60 seconds.

[0070] S902: Color sorting is performed by the seventh channel color sorter to obtain cleaned lotus seeds and uncleaned lotus seeds respectively. Uncleaned lotus seeds are sent to the third storage bin and then sent to step S901, while cleaned lotus seeds are sent to step S802.

[0071] Combine the white and gray materials from steps S7 and S901.

[0072] Further, in step S304, mechanically selected waste material one is obtained through screening; in step S303, mechanically selected waste material two is obtained through screening; in step S302, mechanically selected waste material three is obtained through screening; and in step S6, mechanically selected waste material four is obtained through screening. A second tracked color sorter is used to color sort mechanically selected waste material one, two, three, and four, yielding red lotus seed stalks and waste material, respectively. In step S802, mechanically selected waste material five is obtained through screening, and a second tracked color sorter is used to color sort white lotus seed stalks and waste material, respectively.

[0073] According to NY / T1504-2007, red lotus seed products and white lotus seed products were tested. The test results for red lotus seed products and white lotus seed products are shown in Table 1 and Table 2, respectively.
