Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tea processing, and particularly relates to a processing device and method for rhizoma polygonati tea. BACKGROUND

[0002] Rhizoma polygonati tea is a medicine-food homologous beverage prepared from rhizoma polygonati. The processing process needs to take into account the traditional processing technology (such as "nine steaming and nine drying") and the modern production efficiency. The core is to remove the irritating components of rhizoma polygonati (raw rhizoma polygonati contains mucilage, which is easy to irritate the throat) through processing, while retaining the effective components (such as rhizoma polygonati polysaccharide and saponin).

[0003] In the raw material pretreatment stage, the bubble cleaning machine is used to remove the mud, root hairs and residual epidermis impurities on the surface of rhizoma polygonati, so as to ensure cleanliness. The bubble cleaning machine is composed of a water tank, an air pump, a spraying device and the like. A large number of air bubbles are generated at the bottom of the water tank, so that the rhizoma polygonati rolls in the water, the surface impurities are stripped, and the top spraying device further washes to improve the cleanliness. In the cleaning of rhizoma polygonati, the following defects are found: the diameters of rhizoma polygonati are quite different (3-5 cm for thick ones and 1-2 cm for thin ones), when the air bubble impact force is consistent, the thin rhizoma polygonati is easily rolled excessively by the air bubble, and even washed out of the cleaning area by the water flow; the thick rhizoma polygonati has low rolling frequency due to large weight, and the mud in the surface depressions is difficult to be washed. SUMMARY

[0004] The purpose of the present application is to provide a processing device and method for rhizoma polygonati tea, which forcibly rolls the thick rhizoma polygonati in cleaning to improve the rolling frequency.

[0005] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme:

[0006] A processing device for rhizoma polygonati tea comprises a water tank, an isolation plate fixedly arranged in the water tank to form an upper space and a lower space in the water tank, a plurality of communication holes being formed in the upper space, a plurality of rollers rotationally connected with the water tank and linearly equidistantly arranged, a transmission mechanism for synchronously driving the rotation of the plurality of rollers by meshing connection between a plurality of gears, and a power mechanism which is a power motor and is fixedly connected with one of the rollers at the output shaft thereof on the outside of the water tank. When cleaning, the power motor drives the rollers to synchronously rotate in the same direction to forcibly roll the rhizoma polygonati in contact with the rollers.

[0007] Preferably, the water tank has a cavity at the bottom, the cavity is connected with the air pump device, and a plurality of air holes are formed in the bottom of the water tank, each of the air holes being connected with the cavity. When working, a large number of air bubbles are formed in the water tank.

[0008] Preferably, a screening plate is fixedly connected with the first end of the water tank, the screening plate is arranged obliquely, the lower end of the screening plate is fixedly connected with the isolation plate, a plurality of screening holes are formed in the screening plate, and the screening holes penetrate through the screening plate.

[0009] Preferably, the screening plate is slidably connected to a baffle, and L-shaped plates are fixedly connected to both sides of the baffle. The baffle and the L-shaped plates cooperate to make the baffle and the water tank slidably connected.

[0010] Preferably, the isolation plate has multiple grooves, which are negative spaces in the shape of semi-cylindricals. The diameter of the grooves is slightly larger than that of the roller, and multiple protrusions are provided on the outer periphery of the roller.

[0011] Preferably, the water tank is rotatably connected to multiple rotating shafts, which are located inside the drum and are coaxially arranged with the drum. The rotating shafts are fixedly connected to gears and are fixedly connected to the drum through multiple connecting plates. One of the rotating shafts is coaxially fixedly connected to the output shaft of the power motor.

[0012] Preferably, multiple small holes are made on the outer edge of the roller to connect the inside and outside of the roller.

[0013] Preferably, arc-shaped guide grooves are provided on the side walls of both sides of the roller, and the two ends of the guide grooves are at different straight-line distances from the center of the roller.

[0014] Preferably, an inclined plate is provided above the space between two adjacent rollers, and the two ends of the inclined plate are fixedly connected to the water tank.

[0015] A method for processing Polygonatum sibiricum tea, using Polygonatum sibiricum tea processing equipment, includes the following steps:

[0016] Determine the position of the baffle, which is located at the bottom of the screening plate and in contact with the roller. Place the Solomon's seal rhizomes into the water tank and place them on the screening plate for screening. The thicker Solomon's seal rhizomes will remain on the screening plate, while the thinner Solomon's seal rhizomes will fall through the screening holes.

[0017] After screening, the baffle is raised to allow the thicker Solomon's Seal rhizomes to fall onto the rollers, and then the baffle is lowered. The air pump and motor are started, and bubbles form from the bottom of the water tank and surge upwards, causing the thinner Solomon's Seal rhizomes in the lower space and the thicker Solomon's Seal rhizomes in the upper space to be tumbled. The motor drives each roller to rotate synchronously in the same direction, pushing the thicker Solomon's Seal rhizomes on the rollers forward toward the end of the water tank. At the same time, the protrusions on the outer periphery of the rollers force the contacting Solomon's Seal rhizomes to flip over.

[0018] Guided by the inclined plate, the advancing Solomon's seal rhizomes will flip over the inclined plate and fall back onto the roller. Flipping over the inclined plate is more conducive to the turning of the Solomon's seal rhizomes. At the same time, the rotating roller, due to centrifugal force, will push the water inside the roller out through the small holes, further helping to turn and rinse the Solomon's seal rhizomes above the roller. The rotating roller guides the water near the guide groove to rotate and flow.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] In this invention, the thicker Solomon's Seal rhizome has a greater weight and comes into contact with multiple rollers. The rotation of the rollers causes the thicker Solomon's Seal rhizome to flip over through friction, which significantly increases the flipping frequency of the thicker Solomon's Seal rhizome.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0028] Reference Appendix Figure 1 -Appendix Figure 5 A processing device for Polygonatum odoratum tea includes: a water tank 1; an isolation plate 2, fixedly installed inside the water tank 1, forming an upper space and a lower space inside the water tank 1, with multiple connecting holes 3 on the plate; multiple rollers 4, rotatably connected to the water tank 1 and arranged linearly at equal intervals; a transmission mechanism consisting of multiple gears 15 meshing together to synchronously drive the rotation of the multiple rollers 4; and a power mechanism consisting of a power motor 5 installed outside the water tank 1, with its output shaft coaxially fixedly connected to one of the rollers 4; wherein, during cleaning, the power motor 5 drives each roller 4 to rotate synchronously in the same direction, forcing the Polygonatum odoratum rhizomes in contact with the rollers 4 to turn over.

[0029] Through the above technical solution, the thicker Solomon's Seal rhizome has a greater weight and comes into contact with multiple rollers 4. The rotation of the rollers 4 causes the thicker Solomon's Seal rhizome to turn over through friction, which significantly increases the turning frequency of the thicker Solomon's Seal rhizome.

[0030] The bottom of the water tank 1 has a cavity 6, which is connected to the air pump. The bottom of the water tank 1 also has multiple air holes 7, each of which is connected to the cavity 6. During operation, dense bubbles are formed inside the water tank 1.

[0031] A screening plate 8 is fixedly connected to the first end of the water tank 1. The screening plate 8 is inclined and its lower end is fixedly connected to the isolation plate 2. Multiple screening holes 9 are opened on the screening plate 8 and the screening holes 9 penetrate the screening plate 8.

[0032] The screening plate 8 is slidably connected to a baffle 10, and L-shaped plates 11 are fixedly connected to both sides of the baffle 10. The baffle 10 and the L-shaped plates 11 cooperate to make the baffle 10 slidably connected to the water tank 1.

[0033] Multiple grooves 12 are provided on the isolation plate 2. The grooves 12 are negative spaces in the shape of semi-cylindricals. The diameter of the grooves 12 is slightly larger than that of the roller 4. Multiple protrusions 13 are provided on the outer periphery of the roller 4.

[0034] The water tank 1 is rotatably connected to multiple rotating shafts 14. The rotating shafts 14 are located inside the drum 4 and are coaxially arranged with the drum 4. The rotating shafts 14 are fixedly connected to the gears 15. The rotating shafts 14 are fixedly connected to the drum 4 through multiple connecting plates 19. One of the rotating shafts 14 is coaxially fixedly connected to the output shaft of the power motor 5.

[0035] Multiple small holes 16 are made on the outer edge of the roller 4 to connect the inside and outside of the roller 4.

[0036] Arc-shaped guide grooves 17 are provided on the side walls of both sides of the roller 4, and the two ends of the guide grooves 17 are at different straight-line distances from the center of the roller 4.

[0037] An inclined plate 18 is installed between two adjacent rollers 4, and both ends of the inclined plate 18 are fixedly connected to the water tank 1.

[0038] Working principle:

[0039] Determine the position of baffle 10. Baffle 10 is located at the bottom of screening plate 8 and abuts against roller 4. Place the rhizome of Polygonatum into water tank 1 and place it on screening plate 8 for screening. Screening hole 9 (hole diameter 2cm) divides the rhizome of Polygonatum into "thicker Polygonatum rhizome > 2cm" and "thinner Polygonatum rhizome". The thicker Polygonatum rhizome remains on screening plate 8, while the thinner Polygonatum rhizome falls through screening hole 9.

[0040] After screening, baffle 10 is raised so that the thicker Solomon's seal rhizomes fall onto roller 4, and then baffle 10 is lowered. The air pump and motor 5 are started, and bubbles are formed from the bottom of water tank 1 and surge upwards, causing the thinner Solomon's seal rhizomes in the lower space and the thicker Solomon's seal rhizomes in the upper space to be tumbled. The motor 5 drives each roller 4 to rotate synchronously in the same direction, pushing the thicker Solomon's seal rhizomes on the roller 4 forward to the end of water tank 1. At the same time, the protrusions 13 on the outer periphery of the roller 4 force the contacting Solomon's seal rhizomes to turn over.

[0041] Guided by the inclined plate 18, the advancing Solomon's seal rhizome will flip over the inclined plate 18 and fall back onto the roller 4. Flipping over the inclined plate 18 is more conducive to the flipping of the Solomon's seal rhizome. At the same time, the rotating roller 4, due to centrifugal force, pushes the water inside the roller 4 out through the small holes 16, further helping to flip and rinse the Solomon's seal rhizome above the roller 4. The rotating roller 4, due to the guide groove 17, guides the water near the guide groove 17 to rotate and flow, which helps to further flip the Solomon's seal rhizome.

[0042] It is important to note that:

[0043] The air pump equipment on the bubble cleaning machine is existing technology. When working, it delivers gas through the cavity 6 and various air holes 7 to form upward surging bubbles in the water tank 1, which will not be described in detail here.

[0044] The first and second sections of the water tank 1 are positioned opposite each other. The second section is a conveyor belt or chain plate driven by a conveyor motor, which is used to transport the cleaned Polygonatum rhizomes out of the water tank 1. This is existing technology and will not be described in detail here.

[0045] The diameter of the groove 12 is set in order to avoid obstructing the rotation of the roller 4 with the protrusion 13. The purpose of setting the protrusion 13 on the outer periphery of the roller 4 is to increase the roughness of the contact between the roller 4 and the rhizome of Polygonatum, which is more conducive to the turning of the rhizome of Polygonatum during cleaning.

[0046] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
