This invention discloses a dual-motor hair dryer, relating to the field of hair dryer technology. It includes a housing, a handle, and a mounting cover installed inside the housing. It also includes a dual-system blowing assembly, a drive assembly, a first adjustment assembly, and a second adjustment assembly located inside the mounting cover. In use, the right-side main motor fan system, through the cooperation of the air guide tube, main air duct, and inner air duct, delivers gas to the inner cylinder, evenly passing through the heating element. Simultaneously, the left-side auxiliary motor fan system delivers gas to the outer air duct through the air guide tube, auxiliary air duct, and flow equalization pipe. The gas flows through the annular air cavity, forming an annular air curtain that surrounds the hot air along the central axis. The annular cold air curtain and the hot air along the central axis are coaxially superimposed. Furthermore, the main and auxiliary air ducts are isolated, ensuring that the high temperature of the main air duct does not affect the auxiliary motor, resulting in high operating efficiency for the auxiliary motor. The main motor also experiences stable load due to the smooth air duct, significantly improving the overall energy efficiency and further achieving energy savings.

This invention discloses a sterile, high-pressure, high-speed rotary process for breaking down goat milk into smaller molecules, belonging to the field of food processing technology. The process includes the following steps: after pretreatment, pasteurization, and homogenization, the goat milk undergoes ultra-high pressure homogenization. A homogenizing valve cutting component passes through the milk at high pressure and high flow rate, breaking down large molecules into smaller molecules. Hydrophobically modified xanthan gum-gellan gum-chitosan composite lactase microcapsules are prepared and added to the small-molecule goat milk at a mass ratio of 4‰-6‰ for enzymatic hydrolysis. The mixture is then filtered to obtain sterile, low-lactose, small-molecule goat milk. Ultra-high pressure homogenization achieves the downsizing of goat milk, improving its digestibility and absorption. The composite microcapsule encapsulation of lactase enables efficient lactose hydrolysis. Hydrophobic modification of xanthan gum enhances the encapsulation efficiency and operational stability of the microcapsules. This invention provides a continuous and sterile process, ensuring adequate aseptic protection. The resulting product combines easy absorption due to its small molecular size with low lactose content, making it suitable for lactose-intolerant individuals and those with weak digestive systems.
