The semi-automatic capsule filling machine works on the philosophy of manually feeding an input and automatically doing the entire task of filling capsules with powders, granules, or other substances quickly. This generally operates in three main stages: separation of the capsule, the filling, and then the sealing of the capsule, each step made to enhance the rate of production and at the same time minimizing manual labor.
First, the machine is loaded manually with empty capsules into its capsule tray. It uses a vacuum separator or an air pressure system that differentiates the capsules into two parts: the body and the cap of the capsule. After separation into these two parts, the filling material can then be filled into the capsule bodies. It fills-depending on the specifications-10,000 to 30,000 capsules per hour and is hence ideal to be employed in small to medium-sized operations.
The filling stage is controlled by an automated system giving an accurate record. The filling mechanism of the machine can be adjusted by different dosages to ensure that the right amount of the product will go into each capsule. It is this kind of precision that can cut material waste up to 15%, certainly valuable for expensive ingredients in pharmaceuticals or nutraceuticals.
If filling is complete, the operator manually reassembles capsule bodies with their caps and then reloads them into the machine for sealing. The semi-automatic machines are often fitted out with devices of alignment and capsule locking for correct sealing of the capsules without loss of the product at packaging.
Semi-automatics allow flexibility to the operators in doing quick changes between capsule sizes. This is a good starting point for businesses handling varied lines of products. In some cases, machines are able to handle capsule sizes from #00 up to #4, hence providing a wide range of dosages and products. James Liu, a production manager in the supplement industry, commented on this when saying, “The semi-automatic machines provide the perfect balance between speed and control, especially for businesses with varied needs in production.
The cost of a semi-automatic capsule filling machine usually ranges from USD $8,000 to $25,000, depending on the capacity and features of the machine. Though the initial investment sounds quite huge, savings on labor costs and increases in production efficiency can yield a return on investment as low as 12 months with great ease.
A semi automatic capsule filling machine would be ideal for business enterprises that need a dependable, low-cost solution to scale up their production without giving up the precision of manual filling for automated speeds.
