Capsule making machine

A machine for making capsules, where the capsules each include a container and a dose of product inserted in the container, wherein the container is cup-shaped having an inlet opening, through which the product is supplied into the container before a corresponding lid is applied, and an outer lip surrounding the inlet opening, said machine comprising:

• a feed system for feeding at least a container along a feed path in a direction of feed, said feed system comprising a seat for said container, said machine comprising;
• a filling station positioned along the feed path and comprising at least one filling unit for supplying the dose of product into said container,
• a detecting station positioned along said feed path downstream of said filling station according to said direction of feed and comprising a detecting sensor operating at said seat, said detecting sensor configured to detect a first parameter of said dose of product supplied into said container,
• wherein said detecting sensor is a microwave sensor and said first parameter is the moisture or the density of the dose of product supplied into said first container,
• a control unit in communication with the microwave sensor, the control unit being provided with a volume of the container and being configured to process said first parameter detected by the microwave sensor and to calculate a weight of the dose of the product supplied into the container based on said first parameter and the volume of the container.
