Ingredients: According to the formula requirements, accurately weigh various raw and auxiliary materials, and perform pretreatment such as crushing and sieving to ensure the fineness and uniformity of the materials and prevent foreign matter from mixing.
At the same time, check the content, quantity and other indicators of the materials, and put them into use only after they meet the requirements.
Sol: Add gelatin, plasticizer and water to the gel tank in a certain proportion, heat and stir to dissolve them to form a gel solution. The gel temperature is generally controlled at 60℃-70℃,
and vacuum degassing is performed to remove bubbles in the gel solution to ensure the quality of the gel solution.
The degassed gel solution needs to be kept at 50℃-60℃ and left to stand for more than 4 hours to allow the bubbles to be fully discharged.
Liquid preparation: According to product requirements, the active ingredients are mixed evenly with liquid raw materials such as oils in proportion to make the content liquid.
If the raw material is unstable to light, heat, and oxygen, measures such as light protection, cooling, or nitrogen filling should be taken to prevent the raw material from deteriorating.
Pellet pressing: Add the prepared liquid medicine into the hopper, and the liquid glue is pressed to the soft capsule machine through the rubber pipe to complete the rubber skin preparation, quantitative filling of the contents,
and the rubber skin and contents are pressed into soft capsules through the mold. During the pill pressing process, the process parameters such as the thickness of the rubber skin,
the temperature of the spray body, the speed of the pill pressing,
and the ambient temperature should be controlled to ensure that the quality and appearance of the soft capsule meet the requirements.
Drying: The freshly pressed soft capsules should be immediately transferred to the drying cage for shaping and drying to reduce the moisture content to 25%-30%. At this time, the shape of the soft capsule is basically fixed.
Then transfer it to the tray for further drying until the moisture content of the capsule shell is controlled between 8%-12%. During the drying process, factors such as ambient temperature and humidity,
drying wind speed and drying time need to be controlled to prevent the soft capsules from being too soft,
moldy or brittle.
Quality inspection and packaging
Pill inspection: After drying, the soft capsules need to be inspected manually or by machine to remove unqualified products such as large and small pills, deflated pills, bubble pills, and special-shaped pills to ensure product quality.
Inner packaging: The soft capsules that have passed the inspection are packaged according to customer requirements, such as aluminum-plastic plates, bottles, etc.,
and the packaging materials are disinfected to ensure the sealing and hygiene of the packaging.
Outer packaging: After the inner packaging is completed, the outer packaging is carried out, such as boxing and labeling. The label should indicate the product name, specifications, batch number, production date, expiration date,
ingredients, usage, precautions and other information.
