Abstract
Description
Technical Field
[0001] This utility model belongs to the field of soft capsule production and preparation, and in particular relates to a production and preparation device for soft capsules of phospholipid krill oil. Background Technology
[0002] Krill oil is a natural health food, typically extracted from Antarctic krill, and is rich in various beneficial components. Because it is generally liquid, it is usually sold in soft capsule form for convenience. Soft capsules are a common dosage form; unlike traditional hard capsules, they have a softer outer shell and are typically made from materials such as gelatin and glycerin.
[0003] Current soft capsule manufacturing processes typically include drying the soft capsules to remove moisture from the outer shell, ensuring capsule stability and extending shelf life. However, during drying, soft capsules are prone to cracking or adhering to the drying equipment surface due to their low hardness, leading to material loss and waste, and also affecting the normal operation of the drying process.

[0017] As a further embodiment of this utility model, air filter plates are installed in both the air inlet and the air outlet.
[0018] As a further embodiment of this utility model: a guide roller is also provided inside the housing. The guide roller is movably installed inside the housing via a shaft end, and the bristles on the outer side of the guide roller extend into the drying cylinder through through holes on the surface of the drying cylinder.
[0019] The beneficial effects of this utility model are as follows:
[0020] 1. The present invention provides a production and preparation device for soft capsules of phospholipid krill oil. The device uses a drying cylinder in conjunction with a hot air assembly to dry the soft capsules. The drying cylinder is rotated by a drive motor, causing the soft capsules to be dried to tumble and roll inside the drying cylinder, thereby improving the drying effect. At the same time, the independent design of the drying cylinder makes it easy to disassemble for maintenance and cleaning, preventing impurities or defective soft capsules from sticking and accumulating inside the drying cylinder, which would affect subsequent production and processing.
[0021] 2. The present invention provides a production and preparation device for soft capsules of phospholipid krill oil. The drying cylinder is easily removed from the machine housing through the opening reserved on the side of the machine housing, thereby realizing the maintenance and cleaning of the drying cylinder. At the same time, the maintenance door is provided to seal the opening on the side of the machine housing, thereby realizing the sealing of the internal environment and ensuring internal cleanliness.
[0022] 3. The present invention provides a production and preparation device for soft capsules of phospholipid krill oil. By setting up inlet and outlet baffles to block the inlet and outlet, a certain sealing effect is achieved, allowing air to enter through the inlet and exit through the outlet, thereby forming a gas flow path to dry the soft capsules. This prevents air from leaking through the inlet and outlet, which would reduce the drying effect and increase energy consumption. At the same time, the hinged installation of the inlet and outlet baffles does not affect the loading and unloading of soft capsules, thus ensuring the normal operation of the drying process.
[0023] 4. The present invention provides a production and preparation device for soft capsules of phospholipid krill oil. By using a scraper with a spiral structure, the movement of the soft capsules inside the drying cylinder is controlled by controlling the rotation direction of the drying cylinder, thereby facilitating the discharge of the dried soft capsules through the outlet. At the same time, the brush ring compensates for the gap between the drying cylinder and the machine shell, preventing the soft capsules from falling out of the gap and affecting the normal operation of the equipment.
[0024] 5. The present invention provides a production and preparation device for soft capsules of phospholipid krill oil. When the drying cylinder rotates, the guide roller rotates with the drying cylinder based on the interaction between the outer bristles of the guide roller and the drying cylinder. During the rotation, the bristles unclog the through holes on the surface of the drying cylinder, thereby preventing the soft capsules from sticking or getting stuck in the through holes on the surface of the drying cylinder, thus reducing the number of maintenance treatments for the drying cylinder and saving manpower and resources.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0031] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0032] Please see Figures 1 to 3 This utility model embodiment provides a production and preparation apparatus for soft capsules of phospholipid krill oil, used for drying soft capsules of phospholipid krill oil, including:
[0033] The machine casing 1 has a feed inlet 11, a discharge outlet 12, an air inlet 14 and an air outlet 15 fixedly opened on its side;
[0034] Drying component 2, the drying component 2 comprising:
[0035] The drying cylinder 21 is used to hold soft capsules to be dried, and its outer side is densely covered with through holes;
[0036] The drive roller 22, in cooperation with the driven roller 23, supports the drying cylinder 21. The drive roller 22 and the driven roller 23 are movably mounted inside the housing 1 via shaft ends.
[0037] A drive motor 24 is fixedly installed on the outside of the housing 1, and the power output end of the drive motor 24 is fixedly connected to the shaft end of the drive roller 22.
[0038] Hot air assembly 3, the hot air assembly 3 comprising:
[0039] Multiple heating rods 31 are horizontally arranged below the drying cylinder 21 and are fixedly installed inside the housing 1 by mounting bases 32;
[0040] The exhaust fan 33 is fixedly installed inside the housing 1 and located on one side of the air inlet 14.
[0041] In practical application, the soft capsules to be dried are fed into the drying cylinder 21 through the feed inlet 11. The exhaust fan 33 is activated, and the suction of the exhaust fan 33 causes air to enter the machine casing 1 through the air inlet 14. When the airflow passes through the heating rod 31, it carries away the heat of the heating rod 31, causing the temperature of the gas to rise. Thus, the soft capsules in the drying cylinder 21 are dried by the hot air. At the same time, the drive motor 24 is activated, which drives the drive roller 22 to rotate. With the cooperation of the driven roller 23, the entire drying cylinder 21 is rotated, causing the soft capsules to be dried to tumble and roll inside the drying cylinder 21, thereby improving the drying effect.
[0042] In this embodiment, the drying cylinder 21, in conjunction with the hot air assembly 3, dries the soft capsules. The drying cylinder 21 is rotated by the drive motor 24, causing the soft capsules to be dried to tumble and roll inside the drying cylinder 21, thereby improving the drying effect. At the same time, the independent design of the drying cylinder 21 makes it easy to remove the drying cylinder 21 for maintenance and cleaning, preventing impurities or defective soft capsules from sticking and accumulating inside the drying cylinder 21, which would affect subsequent production and processing.
[0043] Please see Figure 3 In a preferred embodiment of the present invention, a maintenance door 13 is also hinged to the side of the housing 1, a handle 131 is fixedly installed on the maintenance door 13, and an opening is reserved on the side of the housing 1 at the position corresponding to the maintenance door 13.
[0044] In practical application, the opening reserved on the side of the housing 1 allows the drying cylinder 21 to be easily removed from the housing 1, thereby enabling maintenance and cleaning of the drying cylinder 21. At the same time, the maintenance door 13 is used to seal the opening on the side of the housing 1, thereby sealing the internal environment and ensuring internal cleanliness.
[0045] Please see Figure 2 In another preferred embodiment of the present invention, a feed baffle 111 is movably hinged inside the feed inlet 11, and a discharge baffle 121 is movably hinged inside the discharge outlet 12.
[0046] In practical application, this embodiment uses a feed baffle 111 and a discharge baffle 121 to seal the feed port 11 and discharge port 12, achieving a certain sealing effect. This allows air to enter through the air inlet 14 and exit through the air outlet 15, thus forming a gas flow path to dry the soft capsules. This prevents air from leaking out through the feed port 11 and discharge port 12, which would reduce the drying effect and increase energy consumption. At the same time, the hinged installation of the feed baffle 111 and discharge baffle 121 does not affect the loading and unloading of the soft capsules, ensuring the normal operation of the drying process.
[0047] Please see Figure 2 In another preferred embodiment of the present invention, a scraper 211 is fixedly provided inside the drying cylinder 21. The scraper 211 is configured as a spiral structure. A brush ring 212 is fixedly installed at the end of the drying cylinder 21. The brush ring 212 is in flexible contact with the inner wall of the housing 1.
[0048] In practical application, this embodiment uses a scraper 211 with a spiral structure to control the movement of the soft capsules inside the drying cylinder 21 by controlling the rotation direction of the drying cylinder 21. This facilitates the discharge of the dried soft capsules through the outlet 12. At the same time, the brush ring 212 compensates for the gap between the drying cylinder 21 and the housing 1, preventing the soft capsules from falling out of the gap and affecting the normal operation of the equipment.
[0049] Please see Figure 2 and Figure 4 In another preferred embodiment of the present invention, air filter plates 34 are installed in both the air inlet 14 and the air outlet 15.
[0050] In practical applications, this embodiment uses a filter plate 34 to filter the flowing gas, preventing dust from being carried into the housing 1 by external air and causing contamination of the soft capsule.
[0051] Please see Figure 3 In another preferred embodiment of the present invention, a guide roller 4 is also provided inside the housing 1. The guide roller 4 is movably installed inside the housing 1 through a shaft end, and the outer bristles of the guide roller 4 extend into the drying cylinder 21 through through holes on the surface of the drying cylinder 21.
[0052] In practical application, when the drying cylinder 21 rotates, the guide roller 4 rotates along with the drying cylinder 21 based on the interaction between the outer bristles of the guide roller 4 and the drying cylinder 21. During rotation, the bristles clear the through holes on the surface of the drying cylinder 21, thereby preventing the soft capsules from sticking or getting stuck in the through holes on the surface of the drying cylinder 21, thus reducing the number of maintenance operations on the drying cylinder 21 and saving manpower and resources.
