Description

Technical Field

[0001] The present invention relates to the technical field of seed treatment, and particularly relates to a device for dewaxing and impurity removal of Sassafras tzumu seeds. Background Art

[0002] Sassafras tzumu (scientific name: Sassafras tzumu (Hemsl.) Hemsl) is a deciduous tree in the Lauraceae family and the Sassafras genus. It can grow up to 35 meters tall and have a breast diameter of up to 2.5 meters; its bark is smooth, the terminal bud is large, oval, the bud scales are nearly round, the leaves are alternate, gathered at the top of the branches, the apex is gradually pointed, the base is cuneate, the lobes of the leaves are slightly blunt at the apex, firm and papery, green on the upper surface, grayish-green on the lower surface, the petiole is slender, the inflorescence is terminal, blooming before the leaves, with many flowers, densely covered with brownish-yellow pubescence together with the axis of the inflorescence, the bracts are linear to filiform, and the ones at the bottom of the inflorescence are the longest. The flowers are yellow, dioecious; the flower stalks are slender, the flower tube is extremely short, the flower lobes are lanceolate, the filaments are flat, covered with pubescence, the fruit is nearly spherical, and the fruit stalk is red. It blooms from March to April and fruits from May to September. Sassafras tzumu grows fast and has good wood quality. It is an excellent fast-growing timber tree species in southern China and is suitable for building timber forest bases. The trunk is tall and straight, the wood is hard and delicate, with beautiful texture, does not warp or crack, is elastic, has strong compressive resistance, is water-resistant, has a fragrance, and the nail holes are not easy to rust. It is excellent shipbuilding timber and also top-quality timber for construction, bridges, furniture, and farm tools. The mature fruit peel of Sassafras tzumu is blue-black with white wax and contains 30% zinc oil, which is mainly used to make paint and can also be used as a plasticizer in the plastics industry. The bark and roots contain tannins and can be used for tanning leather. The roots can be used as medicine. The tree is tall and straight, with yellow flowers all over the tree before the leaves in early spring and bright red leaves in late autumn, making it a beautiful landscape tree species.

[0003] The fruits of Sassafras tzumu are rich in wax, with the characteristics of a long dormancy period, uneven germination, and it takes 2 - 3 years for all seeds to germinate and emerge from the soil. Therefore, removing the wax on the surface of the seeds before sowing is a prerequisite for seed germination. Currently, in China, methods such as treatment with 98% concentrated H2SO4, high-temperature alkali treatment, high-temperature treatment, mechanical treatment, and sand storage treatment are generally used for dewaxing. Among them, the treatment methods with the highest germination rate are 98% concentrated H2SO4 treatment and high-temperature alkali treatment; however, although the effect of using 98% concentrated H2SO4 treatment is the best, it has strong corrosiveness, is not easily obtained in the market, the waste liquid causes serious environmental pollution, and 98% concentrated H2SO4 is very unsafe. If the operation is slightly careless, it is easy to burn the human skin and seeds. Therefore, treating the seeds with a 3% high-temperature aqueous solution of edible alkali is a very good choice. Currently, the method of treating seeds with a 3% high-temperature aqueous solution of edible alkali is generally as follows: Pour an appropriate amount of seeds into a 3% aqueous solution of edible alkali with a temperature above 85 °C, stir continuously until the solution temperature naturally cools below 50 °C, then wear protective equipment (rubber gloves) and knead the seeds repeatedly until the seeds turn yellowish-white or feel rough when held in the hand, filter out the seeds, rinse them clean, and then germinate them. Manual treatment is not only inefficient but also unable to ensure the health and safety of the treatment personnel. Summary of the Invention

[0009] In the present invention, a high-temperature aqueous solution of edible alkali is placed in a dewaxing tank, and Sassafras tzumu seeds are immersed in the high-temperature aqueous solution of edible alkali. The Sassafras tzumu seeds are repeatedly rubbed by oval elastic sheets arranged in a rubbing cylinder to thoroughly remove the wax on the surface of the Sassafras tzumu seeds.

Embodiment

[0041] Such as Figure 6As shown in the figure, this embodiment makes further optimizations based on Embodiment 1: There is a wax scraping assembly 39 on the first transmission cylinder 8. The number of wax scraping assemblies 39 can be multiple. The wax scraping assembly 39 includes a fixing member 40 and a scraping plate 41. The end of the fixing member 40 is fixedly connected to the first transmission cylinder 8. The scraping plate 41 is a sector plate. The pointed end of the sector plate is rotatably connected to the fixing member 40. There is an elastic member 42 between the scraping plate 41 and the fixing member 40. A through groove 43 is opened on the first transmission cylinder 8. The bottom edge of the through groove 43 is inclined downward and outward, which is convenient for the scraping plate 41 to be inserted. The fixed edge of the through groove 43 is an arc edge. The elastic member 42 squeezes the side facing the first transmission cylinder 8. The scraping plate 41 is squeezed and inserted into the through groove 43. The side of the scraping plate 41 operating on the first transmission cylinder 8 is an arc edge. The seeds move upward under the drive of the spiral blades in the cylinder. The spiral blades give the seeds an upward thrust. The contour edge of the spiral blades contacts the side of the scraping plate 41. The seeds are held against the scraping plate 41. As the spiral blades rotate, the seeds also rotate, so as to rub off the residual wax on the surface of the seeds. When the force given by the spiral plate to the scraping plate 41 is greater than the elastic force given by the elastic member 42 to the scraping plate 41, the scraping plate 41 is extruded out of the first transmission cylinder 8. At this time, the seeds can continue to move upward. When the seeds pass through, the scraping plate 41 enters the first transmission cylinder 8 again under the elastic force of the elastic member and catches the next seed.

[0042] The usage method of this example: Load wet sand into the wax removal box 1. When the seeds pass through the rubbing cylinder 7, the oval elastic pieces 16 arranged in the rubbing cylinder 7 repeatedly rub the Sassafras tzumu seeds to remove most of the wax on the surface of the Sassafras tzumu seeds. Then the Sassafras tzumu seeds are mixed with the sand. At this time, the sand can adhere to the remaining wax. Then, through the spiral conveying method, the Sassafras tzumu seeds after dewaxing and impurity removal are successively washed with warm water and dried with hot air, realizing a series of steps such as dewaxing, impurity removal, subsequent washing and drying of the Sassafras tzumu seeds. Among them, during the process of the first transmission cylinder 8 conveying the seeds, the spiral blades in the cylinder stir the sand and the seeds together, and the sand and the seeds move upward together. When it is conveyed to the top of the first transmission cylinder 8, almost all the sand falls into the wax removal box 1 from the mesh holes of the first transmission cylinder 8. The seeds will continue to be conveyed into the warm water tank 2, and a small amount of sand will also be washed clean by the liquid in the warm water tank 2. Almost no human intervention is involved in the whole dewaxing and impurity removal process, eliminating the threat to the health and safety of the processing personnel in the traditional processing method. Moreover, the dewaxing and impurity removal efficiency is high, the process is safe and reliable, which can improve the dewaxing and impurity removal effect of the Sassafras tzumu seeds and ensure the germination rate of the Sassafras tzumu seeds.

Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
