Abstract

This invention relates to the field of traditional Chinese medicine preparation technology, specifically disclosing a preparation method and application of chicken gizzard lining and angelica ointment. The preparation method includes raw material pretreatment, integrated extraction and concentration, chicken gizzard lining dispersion and mixing, fine homogenization, and degassing and filling steps, all of which are continuously completed in a constant temperature vacuum dynamic extraction and concentration integrated device. This device integrates a constant temperature control unit, a vacuum system, a dynamic stirring unit with flexible scrapers, and an evaporation and condensation unit, enabling efficient extraction of the effective components of angelica and simultaneous solvent recovery under low temperature and vacuum conditions. The stirring unit also provides excellent dispersion and homogenization of high-viscosity materials. The chicken gizzard lining and angelica ointment prepared by this method has a uniform texture and well-preserved active ingredients, making it suitable for preparing drugs for treating pressure ulcers.
