DETAILED DESCRIPTION

[0062] The above and other technical contents, features and effects of the present invention are described in detail below with reference to the attached Figures 1 to 7 It can be clearly presented in the detailed description of the embodiments that the structural contents mentioned in the following embodiments are all referenced to the drawings in the specification.

[0063] This application proposes a processing technology and equipment for Polygonum multiflorum, which are as follows:

[0064] For reference Figure 1 The processing equipment of the present application is composed of a tilting steamer 1 for steaming Polygonum multiflorum, a fixed bottom plate 2 arranged on one side of the tilting steamer 1, a concentrated liquid receiving device 3 and a spare tank 4 detachably arranged on the fixed bottom plate 2, a liquid discharge device 5 for discharging the concentrated liquid in the tilting steamer 1 to the outside, and a drying device 6 and an extending device 7 for drying Polygonum multiflorum. Through the mutual cooperation between the structures, the prepared Polygonum multiflorum can be made dark brown, making its color more beautiful and the cross section black keratin-like, and the content of free anthraquinones in the prepared Polygonum multiflorum can also be increased.

[0065] For reference Figure 1The tilting steamer 1 is an existing device, which has an adapted pot cover for use during the steaming period; it is used to realize the steaming of Polygonum multiflorum, and the device is provided with a bracket 11 for support, and the bracket 11 is further designed, and an extension plate 111 is provided on one side of the bracket 11 for subsequent structures to form a connection relationship with it; secondly, a sandwich pad is placed at the bottom of the tilting steamer 1, and the Polygonum multiflorum is located on the upper side of the pad for steaming, thereby reducing the blockage of the discharge port when the concentrated liquid is collected later.

[0066] For reference Figure 1 A fixed bottom plate 2 is provided on one side of the bracket 11 , and the size of the fixed bottom plate 2 does not affect the position of the tilting steamer 1 after rotation, and the area occupied by the fixed bottom plate 2 is not within the movable range of the tilting steamer 1 .

[0067] For reference Figure 2 A concentrated liquid receiving device 3 and a spare tank 4 are respectively arranged on the fixed bottom plate 2; and a liquid discharge device 5 is arranged and connected to the liquid discharge port of the tilting steamer 1 to discharge the concentrated liquid into the concentrated liquid receiving device 3 or the spare tank 4 for use.

[0068] For reference Figure 2 The concentrated liquid receiving device 3 includes a thermostatic box 31, a rotating disk 32 and a measuring assembly 33. The thermostatic box 31 can be detachably mounted on the fixed bottom plate 2. The rotating disk 32 can be rotatably arranged on the inner bottom wall of the thermostatic box 31. The measuring assembly 33 is arranged on the rotating disk 32 and is coaxially arranged with the thermostatic box 31.

[0069] The thermostatic box 31 is a conventional box that can maintain a constant temperature and has a disinfection lamp; the rotating disk 32 is arranged on the bottom wall of the thermostatic box 31, and the measuring component 33 is arranged on the rotating disk 32, and the measuring component 33 is taken out by rotating the rotating disk 32;

[0070] For reference Figure 2-3When the concentrated liquid is discharged into the measuring component 33 through the liquid discharge device 5, the problem of too much or too little concentrated juice is not avoided. The measuring component 33 is further configured to be a component consisting of a measuring cup 331, a supporting shaft 332 and a visual detector 333. The measuring cup 331 is located on the rotating disk 32 and is used to receive the Polygonum multiflorum concentrated liquid. The supporting shaft 332 is provided with two groups located on the measuring cup 331. The visual detector 333 is provided on the two groups of supporting shafts 332 and is used to detect whether the Polygonum multiflorum concentrated liquid is less than or more than the expected amount. Through the connection of the supporting shaft 332, The support visual detector 333 is located on the measuring cup 331 for visual detection; and the support shaft 332 is provided with two groups, and the visual detectors 333 connected relatively thereto are also provided with two; then in one embodiment, if the expected collected juice is positioned at 100ml milliliters, the difference between the front and the back can be 10ml; then a measuring cup capable of holding 150ml is selected, wherein one visual detector is positioned at 85ml, and the other visual detector is positioned at 115ml, and both visual detectors are connected to a control system, so that when the system learns that the tilting steamer 1 is turned on, After the drainage begins, a visual inspection is performed. When the visual detector at the 85ml position does not send a signal after the tilting steamer 1 stops draining, the system determines that it is abnormal, notifies the staff to observe the drainage problem, and conducts further situation analysis. When passing the 85ml position, the corresponding visual detector sends a signal to the control system, and the visual detector at the 115ml position does not send a sensing signal, it is determined that the received signal is within the predetermined range, that is, it meets the qualified requirements, and then the subsequent process work is carried out in sequence; but when the visual detector at 115ml sends a sensing signal, the tilting steamer 1 does not stop draining when the drainage device 5 controls the continuous drainage into the measuring cup 331. At this time, the control opens the state of conveying the drainage toward the spare tank 4, and the liquid is continuously discharged toward the spare tank 4. During the drainage, the control system sends a warning signal to notify the staff to arrive at the site, handle the liquid in the spare tank 4, and observe the liquid receiving situation in the spare tank 4, adjust the site changes in time, and conduct research again according to the amount of concentrated liquid collected, and make a report analysis structure, and then find problems and rectify them.

[0071] For further reference Figure 4In order to avoid the influence of temperature rise on the visual detector when the measuring cup 331 receives the concentrated liquid, the support shaft 332 supporting the visual detector is further designed to include a three-layer structure of a heat insulation layer 3321, a support plate 3322 and a concave hole 3323. The heat insulation layer 3321 is arranged in close contact with the measuring cup 331 to insulate the concentrated liquid; the support plate 3322 is connected to the other side of the heat insulation layer 3321 away from the measuring cup 331 to fix and support the support plate 3322, and the concave hole 3323 is provided in the middle of the support plate 3322 and corresponds to the visual detector 333, so that the middle of the support plate 3322 has a certain distance from the measuring cup 331, and can also make this position have a better heat dissipation effect. The visual detector is arranged in the middle of the support plate 3322, and the detection end passes through the support plate 3322 to observe the receiving of the measuring cup 331;

[0072] In terms of observation, the visual detector can use a laser sensor, which is set at the corresponding position, and a corresponding reflective plate is set on the opposite side. When the concentrated liquid is received, it affects the reflected signal, thereby obtaining a signal; and the measuring cup 331 is preferably made of transparent glass, and the problem of the reflected signal affected by hot air is pre-processed. This is an existing common signal processing problem, and this application will not go into details.

[0073] For reference Figure 2 , wherein the drainage is realized by a drainage device 5, and in order to make the drainage device 5 practical and beautiful, a further design is made, the drainage device 5 is set to include a drainage pipe 51, an electromagnetic valve 52, a micro pump 53 and a stabilizing shaft 54; the drainage pipe 51 is connected to the drainage port of the tilting steamer 1, and the other end is forked. When the tilting steamer 1 is opened, the concentrated liquid can be drained to a desired position through the drainage pipe 51, and the other end of the drainage pipe 51 is forked and connected to the concentrated liquid receiving device 3 and the spare tank 4; there are two groups of electromagnetic valves 52, and the drainage pipes 51 are respectively set On both sides of the fork, after the tilting steamer 1 is opened normally, the solenoid valve 52 for controlling the flow toward the concentrated liquid receiving device 3 is opened, and the liquid is dripped into the measuring component 33 from the connector arranged on the top of the constant temperature box 31; at the same time, in order to avoid the liquid staying in the drainage tube 51 during drainage, a micro pump 53 is provided, and the micro pump 53 is arranged at one end of the drainage tube 51 close to the tilting steamer 1, for assisting the drainage work of the drainage tube 51; the stabilizing shaft 54 ​​is arranged in the middle of the drainage tube 51, for fixing the drainage tube 51, to avoid the drainage tube 51 being too long or having complex parts that affect the aesthetics.

[0074] Based on the above structure, Polygonum multiflorum is placed in a tilting steamer 1 for steaming, and the concentrated liquid is collected after repeated steaming, and poured into the drying device 6 for drying after being steamed to brown;

[0075] For reference Figure 5 The drying device 6 can be slidably arranged on the extension plate 111. The drying device 6 includes a rotating plate 61, a drying platform 62, a protective plate 63 and a duct connecting shaft 64. The rotating plate 61 is rotatably connected to the drying platform 62 through plastic. The rotating relationship formed by the plastic promotes a seamless connection between the rotating plate 61 and the drying platform 62, thereby reducing the risk of falling from the gap when the Polygonum multiflorum falls. At the same time, in order to promote the stability of the rotating plate 61 after rotation, a positioning shaft 112 is provided at one end of the bracket 11 facing the extension plate 111, and the positioning shaft 112 is clamped with the back of the rotating plate 61 to support the rotating plate 61. 1. The drying platform 62 can be slidably arranged on the extension plate 111. When adjusting the rotating plate 61, it can be assisted by sliding. When the rotating plate 61 is not needed to work, it can also slide outward to make the rotating plate 61 fall on the extension plate 111 in a straight line to work; the protective plate 63 is plugged into the upper surface of the drying platform 62 to prevent the risk of the Polygonum multiflorum from falling; the air duct connecting shaft 64 is connected to one side of the drying platform 62, and can be connected to the external hair dryer through a pipeline for air intake, and the air is supplied to the inside of the drying platform 62 through the fan, so that through the optimization of ventilation, the Polygonum multiflorum can be accelerated to achieve the required working requirements of moistening inside and drying outside.

[0076] For reference Figure 6 In order to meet the coordination between the drying platform 62 and the fan and achieve more beneficial sight drying work, the drying platform 62 is configured to include a drying plate 621, a ventilation slot 622, a ventilation hole 623 and a plug hole 624;

[0077] The drying board 621 is slidably arranged on the extension board 111; the ventilation slot 622 is arranged in the middle of the drying board 621, so that the corresponding two sides of the drying board 621 are connected. There are two corresponding sides on one drying board 621. After the ventilation slot 622 is arranged, the two sides of one corresponding side are connected; a plurality of ventilation holes 623 are arranged equidistantly on the drying board 621 and connected with the ventilation slot 622. The Polygonum multiflorum is laid flat on the drying board 621 on the side with the ventilation holes 623, and the wind is forced to flow from the ventilation slot through the ventilation. 622 comes out upward from the ventilation hole 623, and the drying plate 621 is connected after the ventilation slot 622 is set, so the drying plate 621 on the other side of the corresponding connection with the hair dryer can also discharge air, thereby relatively reducing the situation where the gas pressure escaping from the ventilation hole 623 is too high and the Polygonum multiflorum is lifted up when the wind is strong; the plug-in hole 624 is opened on the side of the drying plate 621 where the ventilation hole 623 is set, and its size corresponds to the protective plate 63, and it is used to plug in the protective plate 63, and the protective plate 63 can also be disassembled and stored when not in use.

[0078] For reference Figure 7Considering that the drying device 6 cannot completely carry the Polygonum multiflorum, an extension device 7 is provided to widen the bearing area of ​​the drying device 6; wherein the extension device 7 includes a drying unit 71 and a bottom block 72; the drying unit 71 has the same function as the drying device 6 and has a substantially same structure, and the drying unit 71 has one less rotating plate than the drying device 6, but has one more protective plate, and the extra protective plate is used to prevent the Polygonum multiflorum from falling out of the side away from the rotating plate 61; there are four groups of bottom blocks 72, which are arranged at the corners at the bottom of the drying unit 71, and the bottom blocks 72 are used to cause the drying unit 71 to be flush with the drying device 6 in height, and through the arrangement of the bottom blocks 72, the bottom of the drying unit 71 is hollowed out, and various receiving plates can be arranged at the bottom of the gap, which can facilitate the collection of the Polygonum multiflorum after drying.

[0079] In one embodiment, it can be achieved by setting up multiple extension devices 7 plus drying devices 6; the drying work, while in another embodiment, all the Polygonum multiflorum can be taken up by the extension device 7 plus the drying device 6, and the drying device 6 can be slid out from the extension plate 111 to transfer the drying position for drying; and the specific embodiment is used by matching the actual size of the user's working environment.

[0080] The processing technology of the Polygonum multiflorum processing equipment includes the following steps:

[0081] In one embodiment, 400 kg of Polygonum multiflorum are selected for operation.

[0082] S1, remove impurities such as residual stems from 400 kg of Polygonum multiflorum, grade, soak, soak, slice, add 100 ml of water into a tilting steamer 1, and steam in the tilting steamer 1 for four hours;

[0083] S2, after four hours of steaming in step S1, the liquid discharge valve at the bottom of the tilting steamer 1 is opened, and the concentrated liquid is collected in the concentrated liquid receiving device 3 through the liquid discharge device 5 for constant temperature and sterile storage; if the liquid discharge exceeds the expected liquid discharge amount during the liquid discharge, the liquid can be drained into the spare tank 4 through the liquid discharge device 5;

[0084] S3, after step S2, if the collected liquid is not concentrated, the staff will make another judgment after inspection and evaluation, and collect the expected amount of 100ml (the deviation does not exceed 10ml) of concentrated liquid, boil it again for four hours, collect the concentrated liquid, and stew it overnight;

[0085] S4, continuing step S3, and boiling again for eight hours without adding water on the second day, collecting the concentrated liquid and then simmering overnight, and continuing to boil for eight hours without adding water on the third day, collecting the concentrated liquid, at this time, the inside and outside of the Polygonum multiflorum are brown, and the concentrated liquid on the second and third days is less, and the total amount of concentrated liquid collected is about 100 ml;

[0086] S5, take out the steamed semi-finished prepared Polygonum multiflorum, pour it into the drying device 6 to dry it until it is moist inside and dry outside, use a carrying tool to collect the Polygonum multiflorum, and then mix the juice collected when the Polygonum multiflorum is steamed in the concentrated liquid receiving device 3 into the semi-finished prepared Polygonum multiflorum in the carrying tool, dry it after it is completely absorbed, sieve out the ash, observe the properties of the finished product and determine the free anthraquinone content.

[0087] In view of the above, the Polygonum multiflorum and the added water are added in equal proportion for steaming. The above is only an equal amount operation method of one embodiment. In another embodiment, the added water can be adjusted in equal proportion based on how many kilograms of Polygonum multiflorum it carries, and the operation is also carried out by selecting a tilting steamer 1 of suitable size.

[0088] In the improved steaming process, 100 liters of water were added for steaming. After about 4 hours of steaming, about 100 liters of juice were collected; the juice was evenly mixed into the processed Polygonum multiflorum; after drying, the surface of the finished product was dark brown, and the cross section was horny and dark brown; since the molecular weight of the bound anthraquinone was less than 500 and it was soluble in water and organic solvents, after adding 100 liters of water, the bound anthraquinone in the Polygonum multiflorum would gradually dissolve in water as it was heated, and the glycosidic bond would break and transform into free anthraquinone under the action of water and high temperature. The study found that when the steaming was about 4 hours, the bound anthraquinone components decreased the most, and at this time the bound anthraquinone was gradually hydrolyzed into free anthraquinone. Therefore, the juice was collected in time after steaming for about 4 hours, so as to reduce the reduction of free anthraquinone due to long-term steaming and heat sublimation; according to the measurement data results, the free anthraquinone content of processed Polygonum multiflorum under the improved process was significantly increased, at least 1 times higher than that of the traditional process.

[0089] The above description is only for illustrating the present invention. It should be understood that the present invention is not limited to the above embodiments, and various variations that conform to the concept of the present invention are within the protection scope of the present invention.
