[0066] Example 4
[0067] like Figures 1 to 4As shown, an embodiment of the present invention provides a device for preparing lychee essence, which comprises: a chassis 3 for mounting a stirring tank 1 and a plug barrel 2, a piston 4 mounted on the plug barrel 2, a metering mechanism 5 for adjusting the position of the piston 4, a servo turntable 6 mounted on the chassis 3, a stand 7 driven by the servo turntable 6, and a premixing tank 8 mounted on the stand 7; wherein, the plug barrel 2, the premixing tank 8, and the stirring tank 1 are provided in plurality, and are evenly distributed around the servo turntable 6; the plug barrel 2 is provided with a liquid extraction port 9 and a liquid discharge port 10; the premixing tank 8 A first feed port 11 is provided at the top and a first discharge port 12 is provided at the bottom; a second feed port 13 is provided at the top of the mixing tank 1 and a second discharge port 14 is provided at the bottom; when the servo turntable 6 drives the stand 7 and the premixing tank 8 to rotate, the first feed port 11 passes directly below each discharge port 10, and the first discharge port 12 passes directly above each second feed port 13; the liquid extraction port 9, the discharge port 10, the first feed port 11, the first discharge port 12, the second feed port 13 and the second discharge port 14 are respectively provided with solenoid valves.
[0068] The following describes a specific embodiment of the preparation device: Liquid raw materials used to prepare the essence can be stored separately in separate liquid storage tanks. Solid raw materials can be dissolved in a solvent and stored separately in separate liquid storage tanks. The liquid extraction port 9 of each plug 2 can be connected to the corresponding liquid storage tank via a flexible hose. The servo turntable 6 rotates the frame 7 and premixing tank 8, positioning the premixing tank 8 below the plug 2. The solenoid valve of the liquid extraction port 9 is opened, and the metering mechanism 5 controls the position of the piston 4 to draw liquid from the storage tank into the plug 2. The solenoid valve of the liquid extraction port 9 is then closed, and the solenoid valves of the liquid discharge port 10 and the first feed port 11 are opened. The metering mechanism 5 then controls the position of the piston 4 to discharge the liquid from the plug 2 into the premixing tank 8. In this manner, the premixing tank 8 is moved sequentially below the corresponding plug 2, and the aforementioned operation is repeated to add the corresponding liquid to the premixing tank 8. The premixing tank 8 is equipped with a first stirring paddle and is adapted to a first drive motor 38, which agitates the liquid within the premixing tank 8 to ensure thorough mixing or reaction. Move the premixing tank 8 above the mixing tank 1, open the solenoid valve at the second feed inlet 13, and close the solenoid valve at the first discharge outlet 12 to discharge the liquid from the premixing tank 8 into the mixing tank 1. Depending on actual needs, the liquids from two or more premixing tanks 8 can be discharged sequentially into the mixing tank 1. The mixing tank 1 is equipped with a second stirring paddle 39 and a second drive motor 40 to agitate the liquids within the mixing tank 1, ensuring thorough mixing or reaction. Furthermore, electric heating elements and temperature controllers can be installed in the premixing tank 8 and mixing tank 1. Electrical equipment mounted on the stand 7 can be powered via slip rings to prevent wiring entanglement. The stand 7 can also be rotated alternately, forward and reverse, to prevent wiring entanglement. A battery can also be placed in the center of the stand 7 to provide power and charge the battery when no flavor is being prepared. This preparation device can be used not only to prepare lychee flavor, but also other flavors. Multiple premixing tanks 8 in this preparation device can simultaneously prepare different premixed flavors. This modulation device facilitates the modulation of flavors in small doses and multiple batches, which facilitates more thorough mixing or reaction. This modulation device can be used for both laboratory flavor modulation and industrial continuous flavor production. It is particularly suitable for complex flavor experiments or production involving a wide variety of liquids. When this modulation device is used in a production line, a conveying mechanism for conveying empty bottles can be arranged below the chassis 3 to receive the finished flavors discharged from the mixing tank 1 and transport them downstream for packaging and packaging. Typically, the number of stoppers 2 is greater than or equal to the number of premixing tanks 8, and the number of premixing tanks 8 is greater than or equal to the number of mixing tanks 1.
[0069] Further, if Figures 4 to 7As shown, the plug cylinder 2 extends in the up-down direction, the liquid extraction port 9 is provided at the lower part of the side wall of the plug cylinder 2, and the liquid discharge port 10 is provided at the bottom end of the plug cylinder 2; the piston 4 is provided with a positioning hole 15 at the upper part of its plug rod; the metering mechanism 5 includes: a positioning member 16, a driving unit for driving the positioning member 16 to enter and exit the positioning hole 15, and a linear motor 17 for driving the driving unit to move up and down; the metering mechanism 5 is installed on the stand 7; there are multiple metering mechanisms 5, which correspond one to one to the premixing tanks 8.
[0070] It should be understood that by closing the solenoid valve of the liquid discharge port 10 and opening the solenoid valve of the liquid extraction port 9; by causing the drive unit to drive the positioning member 16 to insert into the positioning hole 15 of the piston rod 4, and by causing the linear motor 17 to drive the drive unit and the positioning member 16 to move upward, the liquid can be sucked into the plug barrel 2; by closing the solenoid valve of the liquid extraction port 9 and opening the solenoid valve of the liquid discharge port 10; by causing the linear motor 17 to drive the drive unit to move downward, the liquid in the plug barrel 2 can be discharged; in this way, quantitative supply of the liquid can be achieved. By causing the drive unit to drive the positioning member 16 to withdraw from the positioning hole 15 of the piston rod 4, the servo turntable 6 can drive the stand 7, the premixing tank 8, and the metering mechanism 5 to rotate, thereby moving the premixing tank 8 and the metering mechanism 5 to another plug barrel 2.
[0071] Further, if Figure 7 、 Figure 8 As shown, the driving unit includes: a guide cylinder 18, a compression spring 19 installed on the guide cylinder 18, and an electromagnet 20; the positioning member 16 and the electromagnet 20 are distributed at both ends of the compression spring 19; the guide cylinder 18 is provided with a limiting ring 21 at one end where the positioning member 16 is arranged; the positioning member 16 includes: a positioning portion 22 and a guide portion 23; the diameter of the positioning portion 22 is adapted to the inner diameter of the limiting ring 21 and the aperture of the positioning hole 15, and the diameter of the guide portion 23 is adapted to the inner diameter of the guide cylinder 18; the guide cylinder 18 is provided with a connecting plate 24 at one end where the electromagnet 20 is arranged, and the connecting plate 24 is installed on the slider of the linear motor 17; the electromagnet 20 is provided with a limiting portion 25 at one end away from the positioning member 16 to prevent the electromagnet 20 from moving along the guide cylinder 18; the connecting plate 24 is provided with a groove 26 for accommodating the limiting portion 25.
[0072] It should be understood that the diameter of the positioning portion 22 is smaller than that of the guide portion 23. Positioning member 16 is partially or entirely made of ferromagnetic material. Energizing electromagnet 20 draws positioning member 16 into guide cylinder 18, causing positioning member 22 of positioning member 16 to exit the positioning hole 15 of piston rod 4. This allows servo turntable 6 to rotate platform 7, premixing tank 8, and metering mechanism 5, thereby moving premixing tank 8 and metering mechanism 5 to another location on piston rod 2. De-energizing electromagnet 20 causes compression spring 19 to force positioning member 22 of positioning member 16 out of retaining ring 21 of guide cylinder 18, inserting it into the positioning hole 15 of piston rod 4. This allows linear motor 17 to drive the drive unit and positioning member 16 in an upward and downward motion, thereby drawing liquid into or discharging liquid from piston rod 2. The drive unit employing this structure offers faster response, simpler structure, and lower cost. The modulation device can be used in conjunction with a PLC controller or a computer. By adjusting parameters and regulating the movement of the servo turntable 6 and the movement of the linear motor 17, the solenoid valve, and the electromagnet 20, the type and amount of the flavor supplied can be automatically controlled.
[0073] Further, if Figure 6 As shown, the discharge port 10 is provided with an end cover 27 at the outlet end of the solenoid valve. The end cover 27 is provided with a plurality of needles 28 penetrating the upper and lower end surfaces thereof. The aperture of the needles 28 is less than or equal to 2 mm.
[0074] It should be understood that when the solenoid valve of the liquid discharge port 10 opens and the positioning member 16 moves downward, the liquid in the plug barrel 2 is discharged through the needle 28. When the positioning member 16 stops moving, the liquid in the needle 28 stops discharging due to the effect of atmospheric pressure. The small aperture of the needle 28 maintains the stability of the liquid in the needle 28, preventing it from dripping due to imbalance. It also prevents air from entering the barrel, as air is easily compressed while liquid is extremely difficult to compress. This greatly improves the accuracy of the quantitative supply of liquid.
[0075] Further, if Figure 2 、 Figure 4 、 Figure 9 As shown, the stand 7 includes: a vertical cylinder 29, a center table 30 provided at the upper end of the vertical cylinder 29, and an outer ring table 31 provided at the lower end of the vertical cylinder 29; the servo turntable 6 is connected to the center table 30; the lower end of the linear motor 17 is installed on the center table 30, and the upper end is installed on the reinforcing plate 32; the center table 30 is provided with an upwardly extending vertical rod 33, the upper end of the vertical rod 33 is provided with a threaded head and an adaptor nut, and the reinforcing plate 32 is provided with a mounting hole for the threaded head to pass through; the top of the premixing tank 8 is open and is installed at the bottom of the outer ring table 31; the outer ring table 31 constitutes the sealing plate at the top of the premixing tank 8, and the first feed port 11 of the premixing tank 8 is provided on the outer ring table 31.
[0076] It should be understood that a first annular outer edge can be provided on the top of the premixing tank 8, and the first annular outer edge can be bolted to the bottom of the outer ring platform 31. Using the outer ring platform 31 as the sealing plate on the top of the premixing tank 8 not only facilitates the installation of the premixing tank 8, but also eliminates the need for a top plate, thus simplifying its structure.
[0077] Further, if Figure 3 、 Figure 10 、 Figure 11 As shown, it also includes: a ring frame 34; the outer peripheral side of the ring frame 34 is provided with multiple connecting parts 35 and a notch 36 for accommodating the plug barrel 2; the plug barrel 2 is provided with an outer ring part, and the outer ring part is connected to the ring frame 34 by bolts; the chassis 3 is evenly provided with multiple upward extending columns 37 along the edge, and the connecting parts 35 are installed on the top of the columns 37 by bolts; the top of the mixing tank 1 is open and installed on the bottom of the chassis 3; the chassis 3 constitutes the sealing plate at the top of the mixing tank 1, and the second feed port 13 of the mixing tank 1 is provided on the chassis 3.
[0078] It should be understood that the ring frame 34 is detachably connected to the column 37 on the edge of the chassis 3 through the connection portion 35 on the outer peripheral side; by removing the ring frame 34, the stand 7 can be disassembled and assembled; by installing the ring frame 34 and mounting the plug barrel 2 on the ring frame 34, the plug barrel 2 can be arranged above the outer ring platform 31, thereby supplying the premixing tank 8 through the first feed port 11. A second annular outer edge can be provided on the top of the mixing tank 1, and the second annular outer edge can be mounted on the bottom of the chassis 3 by bolts. Using the chassis 3 as the sealing plate on the top of the mixing tank 1 not only facilitates the installation of the mixing tank 1, but also does not require a top plate for the mixing tank 1, which helps to simplify its structure. In addition, support feet can be provided at the bottom of the chassis 3.
