  • Softgel manufacturing process
    Patent number: 5200191
    Abstract: After softgels are encapsulated and dried in a drying tunnel, the resulting softgels are subjected to a further stress relieving step. During the stress relieving step, the temperature and humidity conditions in the drying tunnel are heightened. By utilizing the stress relieving step, the volume and number of dimples and bubbles in the softgels are reduced, and dimensional uniformity is maximized.
