Description

Technical Field

[0001] This invention relates to the field of concentrated liquid crystallization technology, specifically to a device for preparing high-quality zinc gluconate concentrated liquid crystallization particles. Background Technology

[0002] Zinc gluconate is the zinc salt of gluconic acid. It is a white crystalline or granular powder at room temperature and readily soluble in boiling water. Clinically, it is used for zinc-related diseases such as pediatric anorexia, various skin conditions like acne, and recurrent oral ulcers. The preparation of concentrated zinc gluconate crystals involves reaching supersaturation and crystallization, followed by further concentration and crystallization until dryness, or by evaporation. However, existing methods for crystallizing zinc gluconate using these methods suffer from long preparation times, low efficiency, uneven crystal size, and the introduction of other substances during crystallization, resulting in low-quality zinc gluconate crystals. Furthermore, to improve the quality of zinc gluconate crystals, further processing such as sieving the crystallized zinc gluconate granules or powder is required, leading to low production efficiency and low economic benefits. Therefore, we propose a high-quality zinc gluconate concentrate crystallization equipment to solve these problems. Summary of the Invention

[0005] (2) Technical solution

[0006] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0007] A high-quality zinc gluconate concentrate crystallization particle preparation device includes a concentration device and a crystallization device.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example

[0029] like Figure 1 , 2As shown in Figures 3, 4, and 5, an embodiment of the present invention provides a high-quality zinc gluconate concentrate crystallization particle preparation device, comprising a concentration device 1 and a crystallization device 2. A heat exchanger 3 is installed at the bottom of the inner cavity of the concentration device 1, and a compression pump 4 is installed at the bottom of the outer wall of the concentration device 1. The inlet of the compression pump 4 is connected to the solution contained at the bottom of the inner cavity of the concentration device 1, and the outlet of the compression pump 4 is connected to the inner cavity of the crystallization device 2 and is fixedly connected to an atomizing nozzle 5. An air extraction mechanism 6 is installed on one side of the top of the inner cavity of the crystallization device 2, and the opening of the atomizing nozzle 5 points to the air extraction mechanism 6. A vortex tube 7 is installed between the concentration device 1 and the crystallization device 2. The hot flow outlet 701 of the vortex tube 7 is connected to the heat exchanger 3, and the cold flow outlet 702 of the vortex tube 7 is connected to the inner cavity of the crystallization device 2 and points to the atomizing nozzle 5.

[0030] The vortex tube 7 has the characteristic of separating the thermal energy of high-pressure airflow, with one end transmitting hot airflow and the other end transmitting cold airflow. Therefore, in this device, its characteristic is used to conduct heat to the heat exchanger 3 through the hot flow outlet 701 to heat the zinc gluconate solution at the bottom of the concentration device 1, remove moisture and promote crystallization. The zinc gluconate solution that is close to crystallization is sprayed to the top of the inner cavity of the crystallization device 2 through the compression pump 4 and the atomizing nozzle 5 to form a mist. At this time, the cold airflow through the cold flow outlet 702 mixes with the mist solution to cool it down. The solution that was originally in the mist form crystals after cooling. The crystals that are precipitated are flocculent or powdery. Then the air extraction mechanism 6 is activated to extract the flocculent or powdery crystals, while the remaining mist liquid falls to the bottom of the crystallization device 2 for recycling.

[0031] Furthermore, such as Figure 3 As shown, a heating device 8 and a temperature control device 9 are installed at the bottom of the concentration device 1. The heating device 8 acts on the bottom wall of the concentration device 1, and the temperature control device 9 acts on the adjustment part of the heating device 8. A vacuum device 10 is installed on the outer side of the top of the concentration device 1, and the air extraction port of the vacuum device 10 is connected to the inner cavity of the concentration device 1.

[0032] After the heating device 8 is turned on, it heats the zinc gluconate solution contained in the concentration device 1 through the bottom end, promoting the evaporation of water. The temperature control device 9 controls the heating power of the heating device 8 to keep the zinc gluconate solution in the set temperature range. The vacuum device 10 connects to the air extraction port of the concentration device 1 to extract the air and water vapor in it. At this time, the air pressure in the concentration device 1 is lower than the outside air pressure. Under this state, the water in the zinc gluconate solution is more likely to evaporate. Therefore, it can promote internal crystallization at a state below the boiling point of water, maintain the biological characteristics of zinc gluconate, and further improve the quality of its crystals.

[0033] Furthermore, such as Figure 1As shown, a crystallization product chamber 11 is provided on the outside of the crystallization device 2. The outlet of the air extraction mechanism 6 is connected to the top of the crystallization product chamber 11. A rotary distributing hopper 12 is provided at the bottom of the crystallization product chamber 11. The rotary distributing hopper 12 includes an indexing motor 1201 and a separating impeller 1202. The output shaft of the indexing motor 1201 is connected to the central shaft of the separating impeller 1202.

[0034] The suction mechanism 6 absorbs the powdered or flocculent zinc gluconate crystals into the crystallization chamber 11. Then, under the action of gravity, the zinc gluconate crystals fall to the cone at the bottom of the crystallization chamber 11 and then fall into the rotating dispensing hopper 12 for dispensing. The indexing motor 1201 rotates according to the set time or process. When the current separator impeller 1202 is combined into a transfer hopper at the bottom of the crystallization chamber 11, it carries the crystallized powder. After the set time is reached, the indexing motor 1201 drives the separator impeller 1202 to rotate at a set angle, transferring the current transfer hopper from the bottom of the crystallization chamber 11 and then replacing it with another empty transfer hopper, thus realizing timed and quantitative dispensing.

[0035] Furthermore, such as Figure 3 As shown, a collecting hopper 13 is installed at the bottom of the rotating distributing hopper 12, and the outlet at the bottom of the collecting hopper 13 is connected to the packaging container 14.

[0036] The collecting hopper 13 collects the zinc gluconate powder or tiny particles that have rotated to the bottom of the rotating distributing hopper 12 at regular intervals, and then they fall into the packaging container 14 for packaging.

[0037] Furthermore, such as Figure 3 As shown, a temperature detector 15 and a vacuum gauge 16 are installed at the top of the inner cavity of the concentration device 1. The test end of the temperature detector 15 points to the bottom of the inner cavity of the concentration device 1. The output interface of the temperature detector 15 is connected to the temperature control device 9, and the output end of the vacuum gauge 16 is connected to the control switch of the vacuum pumping device 10.

[0038] Temperature detector 15 monitors the temperature of the zinc gluconate solution in the concentration device 1 in real time, keeping it within the set value. When the solution exceeds the set value, it sends a signal to the temperature control device 9 to reduce the heating power of the heating device 8, and vice versa. Vacuum detector 16 monitors the air pressure in the concentration device 1 in real time. When the air pressure exceeds the set value, it sends the current air pressure value to the control switch of the vacuum pumping device 10. The vacuum pumping device 10 increases its power to extract the air from the concentration device 1, maintaining the set air pressure.

[0039] Furthermore, such as Figure 3 As shown, a reflux pipe 18 is installed at the bottom of the crystallization device 2, and the outlet of the reflux pipe 18 is connected to the middle of the inner cavity of the concentration device 1.

[0040] The return pipe 18 is used to transfer the zinc gluconate solution that has failed to crystallize and accumulated at the bottom of the crystallization device 2 back to the concentration device 1 for further concentration and crystallization.

[0041] Furthermore, such as Figure 3 As shown, a first check valve 17 is installed in the pipeline between the compression pump 4 and the concentration device 1, and a second check valve 19 is installed in the middle of the return pipeline 18.

[0042] The first one-way valve 17 prevents the zinc gluconate solution pumped by the compressor pump 4 from flowing back. When the air pressure of the concentration device 1 is lower than that of the crystallization device 2, the sprayed zinc gluconate solution will not flow back into the concentration device 1. The second one-way valve 19 enables the zinc gluconate solution at the bottom of the crystallization device 2 to flow unidirectionally into the inner cavity of the concentration device 1 when the return pipe 18 is working. When the zinc gluconate solution at the bottom of the crystallization device 2 is insufficient, the zinc gluconate solution at the bottom of the concentration device 1 will not flow into the inner cavity of the crystallization device 2.

[0043] Furthermore, such as Figure 1 As shown, the compression pump 4 is a plunger pump, the temperature detector 15 is an inductive detector, and the vacuum gauge 16 is a digital pressure gauge.

[0044] The compression pump 4 is a plunger pump. The plunger pump has high pressure, thus enabling it to spray the zinc gluconate solution into a fine mist through the atomizing nozzle 5. Upon encountering a cold airflow, the mist crystallizes into flocculent or powdery particles. Furthermore, the plunger pump prevents backflow; when the pressure in the concentration unit 1 is lower than that in the crystallization unit 2, the sprayed zinc gluconate solution will not flow back into the concentration unit 1. The temperature detector 15 is an inductive detector, specifically an AR590F infrared thermometer, capable of detecting the temperature of the zinc gluconate solution without contact with it, and transmitting the detected value to the temperature control device 9 to provide temperature data. The vacuum gauge 16 is a digital pressure gauge, specifically a BOOSTPLD0201 digital display pressure gauge, capable of displaying the air pressure inside the concentration unit 1 for easy observation by personnel, and transmitting the detection signal to the vacuum pump 10 to provide an air pressure signal.

[0045] Furthermore, such as Figure 3 As shown, the temperature control range of the inner cavity of the concentration device 1 is 80 degrees Celsius to 90 degrees Celsius, and the gas pressure in the inner cavity of the concentration device 1 is maintained between 0.05 MPa and 0.06 MPa.

[0046] Under the action of the vacuum device 10, the air pressure inside the concentration device 1 is equivalent to 0.5 to 0.6 standard atmospheres. Under this condition, the water in the solution at 80 to 90 degrees Celsius reaches the boiling point and is conducive to evaporation. The zinc gluconate solution evaporated at this temperature has good properties and improves the quality of zinc gluconate crystals.

[0047] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
