A method of preparing a sterile liquid formulation of a high energy fluid in conjunction with a plant component

PendingCN122321016ABiotechnologyHigh energy
This invention provides a method for synergistically preparing sterile liquid formulations using high-energy fluid milling and plant components, relating to the field of traditional Chinese medicine technology. The method involves subjecting medicinal plant raw materials to a first low-temperature treatment using high-energy fluid milling to obtain highly active functional components. These functional components are then mixed with a liquid formulation matrix and subjected to a second low-temperature treatment using high-energy fluid milling, simultaneously achieving homogenization and sterilization. This invention reveals for the first time a significant synergistic sterilization effect between the medicinal plant functional components prepared by a specific process and the high-energy fluid milling treatment. Complete microbial inactivation can be achieved under mild conditions of 120 MPa and below 50°C, with effects far exceeding the simple superposition of a single component and a single physical treatment. This invention provides an integrated homogenization-sterilization method for external preparations and natural beverages that eliminates the need for chemical preservatives and high-temperature sterilization, and has broad applicability in the fields of traditional Chinese medicine and food.

A fresh air device with ultraviolet light air sterilization

This invention discloses a fresh air device with ultraviolet light air sterilization, belonging to the interdisciplinary field of air purification technology and fluid dynamics. The device includes an outer shell with an inner wall coated with an ultraviolet reflective layer; the interior is divided sequentially along the airflow direction into an air intake pretreatment section, a core reaction layer, and a terminal protection and exhaust layer. The core reaction layer contains alternating ultraviolet light sources and porous ceramic carriers coated with a nano-photocatalytic coating, and is equipped with inclined guide plates. When a fan drives airflow through the device, the reflective coating reflects ultraviolet light multiple times to the reaction zone, eliminating blind spots, and the guide plates force the airflow to form a non-linear path, extending the residence time. This invention solves the problems of low light energy utilization and incomplete sterilization caused by airflow short-circuiting in existing technologies through the synergistic optimization of the light field and flow field, significantly improving the microbial inactivation efficiency per unit volume, and is suitable for high-cleanliness environments such as hospitals and laboratories.
