Description

Technical Field

[0001] The invention relates to the technical field of rehydration salt processing, and more specifically to a sodium pyruvate oral rehydration salt processing system and a processing method thereof. Background Art

[0002] The raw materials of sodium pyruvate oral rehydration salt are mostly in powder form. This type of preparation is widely used in the fields of medical treatment, health care and sports nutrition supplementation. Generally speaking, these powder raw materials mainly include basic electrolytes and energy supplement ingredients such as sodium pyruvate, sodium chloride, potassium chloride, sodium citrate, and anhydrous glucose. They are designed to quickly replenish body fluid loss and electrolyte imbalance caused by disease, exercise or high temperature environment through oral administration. After these ingredients are precisely proportioned, they can not only effectively restore body fluid balance, but also promote energy metabolism and accelerate body recovery.

[0003] In practical applications, the sodium pyruvate oral rehydration salt powder can be converted into an easy-to-drink liquid by adding an appropriate amount of water or other suitable liquids for mixing, which is convenient for patients or users to quickly absorb. In addition, in order to meet the needs of use in different scenarios, the powder can be further added with other excipients, such as flavoring agents, colorants, stabilizers, etc., and processed into a solid tablet form through a specific manufacturing process, which is easy to carry and store.

[0004] On the basis of solid tablets, by adding specific effervescent ingredients such as sodium bicarbonate, citric acid, etc., it can be further made into effervescent tablets. Effervescent tablets will quickly produce a large amount of carbon dioxide gas after contacting the liquid, which will drive the tablets to disintegrate rapidly and dissolve evenly in the liquid, forming a solution rich in bubbles, which not only enhances the fun of taking, but also improves the dissolution efficiency and absorption rate. However, when used as effervescent tablets, it is often necessary to design a larger tablet size because it is necessary to ensure that the amount of one tablet can be used in a conventional 500ml thermos or other containers. Although this improves the user experience, it also brings the problem of a longer dissolution time, especially when the water temperature is low or the amount of liquid is small, the dissolution process may be slower. Summary of the invention

[0005] The invention provides a sodium pyruvate oral rehydration salt processing system and a processing method thereof, which have the beneficial effect of making powder into a tablet structure suitable for making effervescent tablets, thereby improving the dissolution speed.

[0030] A sodium pyruvate oral rehydration salt processing system, such as Figures 1 to 5As shown, it includes a frame 101 and two half molds 201, the two half molds 201 are arranged one after the other, the inner side is between the two half molds 201, and the inner end surface of the half mold 201 is provided with a powder cavity 202, and the powder cavity 202 is arranged in a linear array in the left and right directions. Among them, when the two half molds 201 are attached to each other, the powder cavities 202 of each other are aligned one by one to form a complete stepped column cavity. Each stepped column cavity includes a first cylindrical cavity at the upper and lower ends, and a second cylindrical cavity connected between the two first cylindrical cavities. The first cylindrical cavity and the second cylindrical cavity are coaxially arranged, and the diameter of the first cylindrical cavity is greater than the diameter of the second cylindrical cavity. So that a circular annular groove is formed in the middle of the outer wall of the tablet formed in the powder cavity 202, increasing the contact area with the liquid, so as to be suitable for the processing of effervescent tablets. The smaller the diameter of the second cylindrical cavity, the larger the contact area between the effervescent tablet and the liquid.

[0031] To further illustrate, two first electric push rods 203 are fixedly connected to the frame 101, and the telescopic ends of the two first electric push rods 203 are arranged inward, and the telescopic ends of the two first electric push rods 203 are respectively detachably fixed to the outer ends of the two half molds 201. When the two first electric push rods 203 start to extend synchronously, the two half molds 201 gradually approach each other until they fit together.

[0032] Further explanation, combined with Figure 6 and 7 , and also includes an elastic sheet 301, which can be an elastic knitted fabric. A gap 302 extending in the left and right directions is formed in the middle of the elastic sheet 301 by cutting or shearing. A connecting portion 303 is fixed to each of the front and rear ends of the elastic sheet 301. The two connecting portions 303 are respectively fixed to the front and rear sides of the frame 101. The elastic sheet 301 is attached to the bottom of the two half molds 201. The gap 302 extends in the left and right directions and is located in the middle position between the two half molds 201. It also includes two bases 401. The lower end of the base 401 is fixed with a pressing portion 402 that can be inserted into the gap. The two pressing portions 402 are respectively located on the front and rear sides of the frame 101. The telescopic end of the second electric push rod 403 is arranged upward, and the base 401 is fixed to the telescopic end of the second electric push rod 403. The bottom of the pressing portion 402 is rectangular, and the top of the pressing portion 402 is cylindrical. The wide side of the rectangle is smaller than the radius of the cylindrical shape. So as to facilitate insertion into the gap 302. Before the gap 302 is expanded, the elastic sheet 301 is used to carry the sodium pyruvate oral rehydration salt powder, so that when the two half molds 201 are closed, the powder can also be squeezed into the powder cavity 202. When the second electric push rod 403 contracts and drives the pressing part 402 to descend, the bottom of the pressing part 402 is first squeezed into the gap 302. As the pressing part 402 further descends, the top of the pressing part 402 is located in the gap 302, and the gap 302 is expanded, so that the excess sodium pyruvate oral rehydration salt powder can be dropped and recovered. An oblique filter screen can be set below the elastic sheet 301 to make the powder fall, leaving the demoulded tablets.

[0033] Further explained, the telescopic end of the first electric push rod 203 and the half mold 201 connected to it are detachably connected by magnetic attraction, and a connecting column 102 is provided on each of the front and rear sides of the frame 101. Among them, the connecting column 102 includes a first elastic column in the middle, a guide column fixed to the left and right ends of the first elastic column, and a second elastic column fixed to the outer ends of the two guide columns. The first elastic column and the second elastic column are both rubber columns or gas columns, which can bend when under pressure. The diameters of the first elastic column and the second elastic column are smaller than the guide column. The outer ends of all the second elastic columns are fixed to the frame 101. The length of the guide column is not less than the width of the half mold 201. The two half molds 201 are slidably connected to the guide columns located on the left and right sides respectively. The length of the first elastic column and the second elastic column is less than the front and rear width of the half mold 201, so that the two half molds 201 are always on the guide column and cannot fall completely on the first elastic column and the second elastic column. A shifting piece 404 is fixed to the pressing part 402 located on the front side, and the shifting piece 404 is located directly above the first elastic column on the front side.

[0034] When the two half molds 201 are respectively located on the guide pillars on the left and right sides, as the pressing part 402 descends to open the gap 302, the shifter 404 also descends with the pressing part 402 to press down the first elastic pillar, so that the connecting pillar 102 tends to be deformed in a V shape, and then the inner end of the second elastic pillar also tilts downward and bends, and the inner end of the guide pillar also tilts downward, and the two half molds 201 also tilt downward with the inner end of the guide pillar. The inner end of the half mold 201 located on the front side tilts downward while actually moving backward. This is caused by the contraction of the front and rear ends of the first elastic pillar when it is pressed down. Therefore, the half mold 201 located on the front side and the first electric push rod 203 connected to it are separated from the magnetic attraction. Similarly, the half mold 201 located on the rear side and the first electric push rod 203 connected to it are also separated from the magnetic attraction. The built-in exciter of the half mold 201 is started, so that the tablet is demolded and falls by vibration, and the excess powder is shaken off. The base 401 moves downward along with the pressing portion 402 to press down the left and right edges of the elastic sheet 301 , so that the middle of the elastic sheet 301 is sunken downward to form a V-shaped slope to facilitate blanking.

[0035] Combination Figure 8, further comprising a roller seat 501, on which a roller 502 is rotatably connected, a scraper 503 located at the left end of the roller 502 is fixedly connected, and a linear drive mechanism for driving the roller seat 501 to move left and right is fixedly connected to the frame 101. The linear drive mechanism comprises two lead screws 103, which are arranged one in front of the other and rotatably connected to the upper end of the frame 101, and the two lead screws 103 have the same thread rotation direction. The front and rear sides of the roller seat 501 are respectively screw-driven on the two lead screws 103, and the left ends of the two lead screws 103 are driven by the pulley belt assembly 104 to realize synchronous transmission. The output shaft of the motor 105 is set to the right, and the left end of the lead screw 103 located at the front side is fixedly connected to the right end of the output shaft of the motor 105. When the two half molds 201 are combined, the powder is added for the second time above the two half molds 201, so that the powder cavity 202 is further added with powder and the powder is raised upward. Then, the motor 105 drives the lead screw 103 to rotate, and the lead screw 103 drives the roller 502 initially located on the left to move rightward, and the roller 502 rolls the powder on the upper end surface of the two half molds 201, and completely presses the powder into the powder cavity 202 for forming. The scraper 503 hangs off the excess powder.
