Hard capsules are made of two cylindrical shells, each closed off at one end. The upper part, known as the cap, fits perfectly over the lower part, known as the body, to form a hermetically sealed unit. These capsules are produced before being filled with the active ingredient.
The primary types of gelatin used in hard capsules are typically derived from bovine or porcine raw materials. Depending on the formulation and target market group, manufacturers have flexibility in the raw material type. Bovine bone gelatin contributes to capsule firmness, while porcine options offer plasticity and clarity characteristics.
Hard capsules are ideal for powdered or granulated ingredients. These ingredients can be easily filled into the two-piece hard capsules. A standard gelatin hard capsule dissolves in the stomach, under normal conditions, within a certain period after swallowing. Depending on the application, different gelatin types or additional process steps can influence the dissolution process.
In the production of modern Chinese medicine, hard capsules have been widely used in recent years due to their relatively simple process, convenient use, quick effect, and effective isolation of the bad smell of drugs.
Hard capsules are produced on a large machine comprised of polished stainless-steel pins that are dipped in a gelatin mass solution. Within the drying tunnel, the gelatin is dried in a gentle way where the airflow, the temperature, and humidity are precisely controlled.
The filling of hard capsules is an established technology, with equipment available ranging from very small-scale manual filling to intermediate-scale semi-automatic filling.
In conclusion, hard capsules are a crucial part of modern medicine. They offer a convenient, efficient, and reliable method for delivering a wide range of health-promoting ingredients. Whether you’re a healthcare provider, a pharmaceutical manufacturer, or a consumer, understanding the importance and benefits of hard capsules can help you make informed decisions about your health and wellness.
