Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for glue tank equipment, and in particular to a highly efficient and temperature-adjustable plant glue-forming device. Background Technology

[0002] Currently, most soft capsules in my country use animal gelatin as the capsule material. With the growing popularity of all-natural and vegetarian concepts, plant-based soft capsules have attracted widespread attention and become one of the fastest-growing products in the pharmaceutical market. Compared to animal gelatin, plant-based gelatin does not transmit foot-and-mouth disease or mad cow disease, is less prone to contamination, meets the requirements of vegetarians, and is suitable for the storage and transportation of aldehyde-containing drugs, among other advantages. However, the gelatinization process for plant-based gelatin differs from that for gelatin, and it places new demands on gelatinization equipment compared to traditional gelatinization techniques.

[0003] In traditional animal gelatin production, the gelatin powder is added only when the glycerin-water mixture reaches a certain temperature, and the gelatinizing tank does not need to be cooled during multi-batch production. Currently, most plant-based gelatins on the market are made from modified starch or compounded with modified starch as the base. When adding gelatin during the production of plant-based soft capsules, if the temperature of the water and glycerin mixture is high (above 40°C), the gelatin powder is prone to caking due to heat. During the gelatinizing process, there will be undissolved dry powder in the gelatin solution, resulting in more defective products in subsequent production processes and affecting product yield. Therefore, when producing plant-based gelatin in multiple batches, the gelatinizing tank needs to be cooled between batches. However, relying on the gelatinizing tank to cool down naturally takes a long time, which seriously affects the production efficiency of plant-based soft capsules. Utility Model Content

[0036] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0037] like Figure 1 As shown, a high-efficiency temperature-adjustable plant gum dissolving device includes a dissolving tank 2, a heat transfer oil tank 1, an oil pipeline 3, and an electrical distribution box 4.

[0038] The heat transfer oil tank 1 is equipped with a heating device 5 for heating the heat transfer oil in the heat transfer oil tank 1.

[0039] The adhesive tank 2 includes a tank body, an inner wall 201, an outer layer 202 and an outer wall 203. The outer layer 202 is used to hold the heat transfer oil transported from the heat transfer oil tank 1 and to provide a heat source for the adhesive liquid. The tank body is equipped with a stirring device 6 for stirring the materials inside the tank. The top of the tank body is equipped with a spray device 7 for cooling the tank body. The top of the tank body is equipped with a feeding port 10. The tank body is equipped with a temperature detection device 8. The bottom of the tank body is equipped with a discharge valve 11.

[0040] The oil pipeline 3 includes an inlet pipe 301, an outlet pipe 302, a drain pipe 303, and a return pipe 304. The bottom outlet 101 of the heat transfer oil tank 1 is connected to the heat transfer oil pump 12 through the outlet pipe 302. The heat transfer oil pump 12 is connected to the bottom inlet of the jacket 202 through the inlet pipe 301. The bottom inlet of the jacket 202 is directly connected to the top return port 102 of the heat transfer oil tank 1 through the return pipe 304. The top outlet of the jacket 202 is connected to the top return port 102 of the heat transfer oil tank 1 through the drain pipe 303. A return valve 13 is provided on the return pipe 304. A vent valve 14 is provided at the highest point of the drain pipe 303 for the circulation and venting of the heat transfer oil.

[0041] like Figure 2 As shown, the power distribution box 4 includes a main power switch 401, a heating switch 402, a stirring switch 403, a thermal oil pump switch 404, and a mode selection switch 405, which are used to control the opening and closing of each device; the heating switch 402, stirring switch 403, thermal oil pump switch 404, and mode selection switch 405 are connected in parallel and then connected to the main power switch 401.

[0042] In use, the heat transfer oil is first heated by the heating device 5 in the heat transfer oil tank 1. When the heat transfer oil reaches a certain temperature, the plant gum, water, glycerin, and additives are put into the tank through the feeding port 10. The stirring device 6 is turned on to stir the materials evenly. At this time, the valve on the return oil pipe 304 and the vent valve 14 on the drain oil pipe 303 are closed, and the heat transfer oil pump 12 is turned on. The heat transfer oil in the heat transfer oil tank 1 enters the jacket 202 of the glue dissolving tank 2 through the inlet 204 via the heat transfer oil pump 12. When the jacket 202 is full of heat transfer oil, the heat transfer oil flows back to the heat transfer oil tank 1 through the drain port 205 and the drain pipe 303, completing the heat transfer oil circulation and achieving the purpose of continuous heating of the materials in the tank by the heat transfer oil. At the same time, the stirring device 6 is turned on. The material inside the tank is stirred to ensure uniform mixing and the formation of a stable plant-based adhesive. After the adhesive is dissolved and discharged from the tank, the heat transfer oil pump 12 is turned off, and the return oil valve 13 on the return oil pipe 304, the vent valve 14 on the drain oil pipe 303, the spray device 7 at the top of the tank, and the discharge valve 11 at the bottom of the tank are opened. At this time, the heat transfer oil in the jacket 202 and the oil pipeline 3 can quickly flow back to the heat transfer oil tank 1. Simultaneously, the spray device 7 is opened to quickly remove most of the heat from the tank with clean water. Hot water is discharged from the discharge valve 11 at the bottom of the tank. When the tank temperature is lower than the required temperature, the spray device 7 and the valve at the bottom of the tank are closed to complete the cooling of the tank. The above steps are repeated to complete the dissolution of the next batch of plant-based adhesive. Through the above operation, the natural cooling process of the tank is avoided, reducing the time required for cooling the tank and greatly saving time costs.

[0043] like Figure 3As shown, the heating device 5 includes a heater 501, a first temperature sensor 502, and a first temperature controller 503, which are used for heating the heat transfer oil and controlling the temperature of the heat transfer oil.

[0044] When the heat transfer oil pump 12 is working and the jacket 202 and the oil pipeline 3 are full of heat transfer oil, the volume of heat transfer oil occupies 1 / 2 of the volume of the heat transfer oil tank 1, ensuring that sufficient heat transfer oil can be provided to the jacket 202. The heater 501 is located at 1 / 3 of the volume of the heat transfer oil tank 1, which can ensure that the lowest point of the liquid level in the heat transfer oil tank 1 is above the horizontal plane of the heater 501, preventing the heater 501 from burning dry.

[0045] After the heat transfer oil pump 12 stops and the heat transfer oil in the jacket 202 and the circulating pipeline is emptied, the volume of the heat transfer oil occupies 4 / 5 of the volume of the heat transfer oil tank 1. This ensures that when the amount of heat transfer oil in the heat transfer oil tank 1 is at its maximum, the volume of the heat transfer oil does not exceed the volume of the heat transfer oil tank 1, thus preventing the heat transfer oil from overflowing.

[0046] The stirring device 6 further includes a motor 601, a stirring rod 602, and stirring blades 603. The motor 601 is fixedly connected to the top of the tank. The top of the stirring rod 602 passes through the tank and is connected to the output end of the motor 601. The stirring blades 603 are fixed on the stirring rod 602. Multiple sets of stirring blades 603 are provided. The motor 601 drives the stirring rod 602 to rotate, which in turn drives the multiple sets of stirring blades 603 on the stirring rod 602 to rotate, thereby stirring and mixing the materials in the tank.

[0047] The temperature detection device 8 also includes a second temperature sensor 801 and a second temperature controller 802. The second temperature sensor 801 is in contact with the inner wall 201 and can measure the temperature of the inner wall 201 of the tank.

[0048] The spraying device 7 further includes a water inlet pipe 701, a spray valve 702, and a spray head 703. The water inlet pipe 701 is fixed to the top of the tank, and the lower end of the water inlet pipe 701 is connected to the spray head 703. The spray valve 702 is installed on the water inlet pipe 701. The spray valve 702 is a solenoid valve, which is jointly controlled by a mode selection switch 405 and a second temperature controller 802. The mode selection switch 405 is divided into a gelling mode and a cooling mode. When the mode is selected... When switch 405 is in the gelling mode, spray valve 702 is closed. When the mode selection switch 405 is in the cooling mode and the temperature of the inner wall 201 of the tank is greater than 40°C, the second thermostat 802 is closed, and spray valve 702 is automatically opened. Clean water is evenly sprayed from spray head 703 onto the inner wall 201 of the tank to cool the tank. When the temperature of the inner wall 201 of the tank is less than 40°C, the second thermostat 802 is opened, and spray valve 702 is automatically closed, completing the cooling of the tank.

[0049] The return oil valve 13 on the return oil pipe 304 is a solenoid valve, controlled by the heat transfer oil pump switch 404 and linked with the heat transfer oil pump 12. When the heat transfer oil pump 12 is turned on, the solenoid valve is closed to prevent the heat transfer oil from flowing back to the heat transfer oil tank 1 through the return oil pipe 304. When the heat transfer oil pump 12 is turned off after the gelling is completed, the solenoid valve is turned on, allowing the heat transfer oil in the jacket 202 to flow back to the heat transfer oil tank 1 through the return oil pipe 304, so that the tank loses its heat source.

[0050] The vent valve 14 is a solenoid valve controlled by the heat transfer oil pump switch 404. The vent valve 14 on the oil drain pipe 303 is linked with the heat transfer oil pump 12. When the oil pump is turned on, the vent valve 14 is closed to prevent the heat transfer oil from overflowing the pipe. When the oil pump is turned off, the vent valve 14 is opened to accelerate the flow of heat transfer oil in the jacket 202 and the oil pipeline 3 back to the heat transfer oil tank 1.

[0051] The oil inlet of the interlayer 202 is positioned higher than the oil inlet of the heat transfer oil tank 1, ensuring that all the heat transfer oil in the interlayer 202 flows out after the gelling is completed, and the interlayer 202 becomes hollow.

[0052] The heat transfer oil tank 1 is also equipped with a breather valve 9 to ensure that the heat transfer oil tank is in communication with the external environment and to prevent the formation of positive or negative pressure in the tank.

[0053] How to use:

[0054] During the production process, the heating device 5 is first set to heat the heat transfer oil in the heat transfer oil tank 1. When the heat transfer oil reaches the set temperature, the material is put into the tank, the stirring device 6 is turned on to stir the material evenly, the heat transfer oil pump 12 is turned on, and the return oil valve 13 and the vent valve 14 are linked with the heat transfer oil pump 12 and automatically close. The heat transfer oil is fed into the jacket 202 of the adhesive tank 2 through the heat transfer oil pump 12. Because the return oil valve 13 is closed, the heat transfer oil in the jacket 202 is prevented from flowing back to the heat transfer oil tank 1 through the return oil pipe 304. Because the vent valve 14 is closed, the heat transfer oil is prevented from overflowing the pipe. When the jacket 202 is full of heat transfer oil, the heat transfer oil flows back to the heat transfer oil tank 1 through the drain pipe 303. The heat transfer oil heats the material in the tank, and at the same time, the stirring device 6 is continuously turned on to stir the material in the tank, thereby forming a stable and uniform plant adhesive liquid.

[0055] After the adhesive is dissolved and the adhesive liquid is discharged from the outside of the tank, the heat transfer oil pump 12 is turned off. At the same time, the return oil valve 13 and the vent valve 14 on the oil drain pipe 303 are linked with the heat transfer oil pump 12 and automatically open. The jacket 202 and the oil pipeline 3 are quickly vented, and the heat transfer oil in the jacket 202 and the oil pipeline 3 flows back to the heat transfer oil tank 1, so that the tank quickly loses its heat source.

[0056] Meanwhile, the spray valve 702 is jointly controlled by the mode selection switch 405 and the thermometer. The mode selection switch 405 is divided into a gelling mode and a cooling mode. When the mode selection switch 405 is in the gelling mode, the spray valve 702 is normally closed. When the mode selection switch 405 is in the gelling mode and the temperature of the inner wall 201 of the tank is greater than 40°C, the spray valve 702 automatically opens, and clean water is evenly sprayed from the spray head 703 onto the inner wall 201 of the tank to cool the tank. When the temperature of the inner wall 201 of the tank is less than 40°C, the spray valve 702 automatically closes. Before the plant glue is produced, the gelling mode is selected, and the spray valve 702 is in the closed state. After the plant glue has been gelled, the cooling mode is selected, and when the tank temperature is high (greater than 40°C), the spray valve 702 automatically opens to spray the tank to cool it down. When the temperature on the thermometer is less than 40°C, the spray valve 702 automatically closes, and the tank cooling is completed. Repeat the above steps to complete the next batch of plant-based gumming.

[0057] By performing the above operations, the natural cooling process of the tank is avoided, and by linking the pipeline valves and spray valve 702 with other parts, the automation level of tank cooling is improved, greatly increasing work efficiency.

[0058] In summary, this invention can rapidly change the temperature of the dissolving tank by controlling the amount of heat-conducting oil in the jacket and coordinating with the spraying device according to the dissolving process of plant gum, thereby meeting the dissolving requirements of plant gum and improving production efficiency.
