How to Apply Hpmc Coating Solution.
HPMC coating solution is a popular choice for pharmaceutical and food supplement manufacturers to improve the appearance, taste and stability of their products. However, applying HPMC coating can be a challenging process for those who are not familiar with it. In this article, we will provide you with a step-by-step guide on how to apply HPMC coating solution to your products.
Preparing the HPMC Coating Solution.
Before starting the process of applying the HPMC coating solution, it is essential to prepare the materials and equipment required for the task. These include:
• HPMC coating solution.
• A spray gun equipped with an air compressor.
• An HPMC coating pan.
• A drying chamber.
• A stirring machine.
Once you have all the necessary supplies, it is time to prepare the HPMC coating solution. For this, you need to mix the solution with filtered water and stir it thoroughly using a stirring machine. The ratio of water to HPMC solution depends on the concentration of the solution, and the weight of the product to be coated. A typical ratio is 1:1.5 parts of water to HPMC solution. Ensure that the mixture is fully homogeneous and free from any lumps before proceeding.
Applying the HPMC Coating Solution.
Once you have prepared the coating solution, you can proceed to coat your products. Follow the below steps:
Step 1: Load the product onto the coating pan.
Step 2: Adjust the spray gun's pressure to ensure a uniform coating.
Step 3: Start the air compressor and turn on the spray gun to begin coating the product.
Step 4: Spray the product in a circular motion while maintaining a distance between the spray gun and the product.
Step 5: Monitor the coating thickness and quality to ensure that it is uniform and free from any excess moisture.
Step 6: Once the product is adequately coated, transfer it to the drying chamber.
Drying the Coated Product.
After coating the product with HPMC solution, it’s necessary to dry it completely to prevent any moisture retention. For this, the coated product is kept in a drying chamber that regulates humidity and temperature. The drying process allows the HPMC coating to form a thin layer on the product surface, giving it an attractive and smooth finish.
Quality Check.
As a final step, it’s essential to conduct a quality check to ensure that the coated product meets its desired specifications. Typically, quality checks involve inspecting the coating thickness, uniformity, and overall texture. Any coated products that do not meet the quality parameters should be rejected and reprocessed.
Conclusion.
Applying HPMC coating solution requires precise control and attention to detail. If done correctly, it can improve the aesthetic appearance and taste of your products while extending their shelf life. However, it’s crucial to use high-quality materials and equipment and follow the proper procedures to achieve the best results.
