Hollow hard capsule refers to a certain amount of raw material extract or raw material powder that is directly filled into hollow capsules, or several raw material powders are mixed and then filled into hollow capsules, which are manufactured and processed by special Capsule Equipment Machine . The main molding material is gelatin. Bone glue made of bone is hard and brittle. Pigskin gelatin made from pigskin has good plasticity and is an ideal choice for mixing bone skin and gelatin. In order to increase its toughness and plasticity, add the appropriate amount of glycerin, sorbitol, CMC Na, HPC, sodium oleamide sulfonate, etc.; to reduce its fluidity and increase gelling ability, add thickener agar; drug sensitivity to light, You can add a masking agent of titanium dioxide (2% to 3%); in order to increase the aesthetics and easy identification, you can add lemon yellow, carmine and other food colors as coloring agents; to prevent the capsule from becoming moldy, you can add preservatives, such as Parabens.

The hollow hard capsules manufactured by the Empty Hard Capsules Manufacturers have the following characteristics:
The appearance is smooth and beautiful, can cover up the inappropriate bitterness and peculiar smell of the raw materials, and is easy for consumers to accept; the bioavailability of the functional factors is high, and the amount of auxiliary materials is small. During the preparation process, no adhesive is added, and no pressure is applied, and it disintegrates rapidly in the gastrointestinal tract.

For example, vitamins should be placed in opaque hard capsules for easy storage; it can prolong the release of healthy functional substances. The raw materials are first made into granules and then coated with materials with different release rates, mixed evenly in proportions, and filled into empty capsules to achieve the purpose of prolonging the efficacy of the medicine.
