Description

Technical Field

[0001] The utility model relates to the technical field of soft capsule production, in particular to a rotary cage feeding structure of a soft capsule drying machine. Background Art

[0002] Soft capsules, also known as soft pills, are a type of capsule packaging. They are made by sealing liquid drugs or liquid-solid drugs in soft capsule materials. This type of soft capsule material is mainly made of gelatin, glycerin or other suitable pharmaceutical excipients alone or in combination. The newly made soft capsules contain a lot of water and need to be dried before use.

[0003] Traditional soft capsules are generally dried naturally or by using a tray-type capsule drying device to heat and dry the capsules. However, this can easily cause uneven heating of the capsules, resulting in capsule deformation, melting, partial hardening of the outer surface of the capsule, and adhesion.

[0004] Or, as provided in the publication number "CN219264789U", an anti-sticking rotating cage for the production of promestriene soft capsules, the device enables the spiral feeding part to move the material back and forth in the cage body through the forward and reverse rotation of the forward and reverse motor, and then cooperates with the separation and stirring action of the breaking part to enable the material to fully contact with the hot air flow, thereby improving the drying efficiency and avoiding the problem of material sticking to each other.

[0005] However, the above device still has the following problems during implementation:

[0006] When the device is in use, during heating, hot air can enter the cage through the through hole for drying, but in the process of the hot air drifting upward, a certain amount of hot air will be emitted outward, resulting in a significant reduction in the hot air entering the cage, thereby greatly reducing the drying efficiency.
