Description

Technical Field

[0001] The present invention relates to the technical field of deep processing of agricultural products, and in particular to a three-dimensional layout lotus seed production line. Background Art

[0002] Lotus seeds are the seeds of the Nelumbo nucifera plant, a member of the Nelumbo family. Starting in June each year, when the fruit is ripe, the lotus pods are harvested, the fruit is removed, the peel is removed, and the dried fruit becomes red lotus seeds. Red lotus seeds are processed and peeled to become white lotus seeds. Lotus seeds are further divided into cored and uncored lotus seeds. In addition, the lotus seed residues, cores, peeled ash, and broken lotus seeds from the lotus seed processing process are all sold as by-products.

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

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

[0005] 2. Source: White lotus seeds are made from peeled red lotus seeds, while red lotus seeds are the product of dried fruits.

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

[0007] 4. Applicable groups: White lotus seeds are often suitable for people with poor digestive tract 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, so people with yin deficiency, excessive fire, damp heat, or excess heat should not eat white lotus seeds. Red lotus seeds replenish blood, so people with weak constitutions or high blood pressure should not eat them.

[0009] Existing lotus seed production lines can produce red lotus seeds, cored red lotus seeds, white lotus seeds, and red and white lotus seeds. These production lines require a large amount of equipment, and a flat layout would require a significant area and high investment costs. Furthermore, the processing (such as shelling, sieving, core removal, skin grinding, and screening) generates significant dust and noise. Manual selection requires a good environment, away from noise and dust. Summary of the Invention
