AI Technical Summary

Technical Problem

During the preparation of dental strips, the drying process is not stable enough, which leads to uneven drying, surface skin formation, and failure of heat-sensitive active ingredients.

Method used

A multi-stage drying system is used, with zoned control of air intake speed, exhaust speed, and air intake temperature to construct a stepped drying curve. Combined with carrier film tension control, this ensures uniform drying of the wet film and protection of active ingredients at different stages.

Benefits of technology

This improved the uniformity and appearance of the teeth whitening strips, effectively protecting heat-sensitive active ingredients such as whitening agents, and ensuring the product's immediate effectiveness and long-term storage stability.

Abstract

This invention discloses a manufacturing process for dental strips, belonging to the field of dental strip manufacturing technology. The manufacturing process of this invention divides the drying equipment into multiple independent and controllable drying sections, and finely regulates the air intake and exhaust volume of each section, constructing a stepped, asymmetric drying curve. Furthermore, this invention is applicable to dental strips with specific formulations and, by combining drying with tension control of the carrier film, effectively solves the problems of uneven drying, surface skinning, and wrinkles. It also effectively protects heat-sensitive active ingredients such as whitening agents, ensuring the uniformity and appearance quality of the dental strips.
