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.

The utility model relates to the technical field of boiler heating, and discloses a device for improving the heat efficiency of a boiler, which comprises a boiler base, and a boiler body is fixedly arranged at the upper part of the boiler base; by controlling the boiler base, the pot body and the supporting seat to form a sealed space, when the thermal resistance wire is controlled for heating, the distance between the thermal resistance wire and the pot body can be changed by further controlling the electric telescopic rod, when the thermal resistance wire is far away from the pot body, the pot body mainly obtains heat in hot air, so that the temperature of the pot body is mild, and when the thermal resistance wire is close to the pot body, the electric telescopic rod can be further controlled to change the distance between the thermal resistance wire and the pot body. The temperature of the pot body is high, raw materials can be rapidly heated, in the heating process of the thermal resistance wire, part of hot air is conveyed into the conveying pipe, the conveying pipe is opened by controlling the valve, the hot air further enters the telescopic guide pipe and enters the cover body through the telescopic guide pipe, and the hot air is recycled in the pot body.

This invention provides a method for preparing asymmetric disubstituted amides, comprising the following steps: (1) a primary amine compound of formula I undergoes a condensation reaction with a carboxylic acid or carboxylic acid ester compound of formula II to obtain a compound of formula III; (2) a compound of formula III reacts with an alkylating agent to obtain a compound of formula IV. This invention synthesizes asymmetric disubstituted amides with high product purity, high yield, and good product quality. The raw materials used in the synthesis route are inexpensive and readily available, avoiding the use of expensive secondary asymmetric amines. The route is suitable for industrial production and has versatility, solving the problem of high prices and scarce supply of secondary asymmetric amines in the current market. All reactions in this invention are carried out at mild temperatures, are safe and controllable, and do not involve the use of flammable or explosive hazardous chemicals, making it more valuable for industrial applications.

The utility model discloses a kind of heat preservation and thermal insulation packaging, including a bag body, bag body has a multi-layer structure, the multi-layer structure at least includes an outer layer support film layer, a barrier layer being arranged in the inner side of outer layer support film layer and an inner layer heat seal layer being arranged in the inner side of barrier layer, barrier layer and inner layer heat seal layer between being provided with a non-woven fabric layer.The utility model sets up non-woven fabric layer between barrier layer and inner layer heat seal layer, effectively solve the problem that the heat preservation and thermal insulation performance of packaging bag is limited and use experience is poor.Non-woven fabric layer forms a high-efficiency thermal resistance barrier in packaging bag structure by the air retained in its porous structure as the poor conductor of heat and the low thermal conductivity characteristics of fiber.
