What is dynamic high-pressure microjet? Why is the dynamic high-pressure micro-jet homogenizer more effective than the traditional high-pressure homogenizer? Dynamic high-pressure microjet technology (dynamic high pressure microfluidization (DHPM) is an advanced high-pressure processing technology. It is based on high pressure theory, fluid mechanics theory, and impinging stream theory. It integrates multiple unit operations such as transportation, mixing, micro-crushing, pressurization, and expansion. It can perform a series of comprehensive effects such as strong shearing, high-speed impact, instantaneous pressure release, high-frequency oscillation, expansion and cavitation on fluid mixed materials, thereby achieving good miniaturization, Microemulsification and homogenization effect. Dynamic high-pressure technology represents an important innovation because it can be used to modify emulsions or biopolymers and can be used in industrial production.

Application principle of dynamic high-pressure microjet technology

Dynamic high-pressure microjet is a special form of high-pressure homogenization technology. Dynamic high-pressure microjet homogenizer is developed on the basis of dynamic high-pressure microjet technology, with the main purpose of realizing emulsification and homogenization of materials. A technical equipment. The dynamic high-pressure microjet homogenizer is mainly composed of a hydraulic pump and an impact chamber. It uses the high pressure generated by the hydraulic pump to disperse the fluid in the impact chamber into two or more streams, and perform a strong high-speed impact in an extremely small space. Most of its energy is instantly transformed during the impact process, creating a huge pressure drop, which makes the liquid particles highly fragmented. It is a brand-new technology that integrates multiple unit operations such as transportation, mixing, micro-crushing, pressurizing, heating, and puffing. It is mainly suitable for shearing, crushing, homogenization and expansion of liquid-liquid phase or liquid-solid phase of fluid mixed materials. In this homogenization process, severe processing conditions such as high-speed liquid impact, high shear, hole explosion, high-speed oscillation, etc. may cause changes in the macromolecular structure, thereby causing changes in the physical properties of the material.【1】

In microjet homogenizers, in order to achieve the effect of jet collision, the main mechanical form is the use of high-speed liquid streams to spray onto solid materials (liquid-solid collision) and collision between high-speed fluids (liquid-liquid collision). Therefore, the design of the impingement chamber is the core element that determines the effect of the dynamic high-pressure microjet homogenizer.

Dynamic high-pressure microjet homogenizer

Dynamic high-pressure microjet technology integrates high-pressure jet technology, impinging stream technology and traditional high-pressure homogenization technology, and has a more efficient, stable and safe nano-scale material processing effect.

A series of high-pressure microjet homogenizers manufactured by Genizer Company of the United States using dynamic high-pressure technology have a greatly improved pressure compared with traditional high-pressure homogenizers. The application of microjet technology makes it very different in working principles from traditional valve-type high-pressure homogenizers. During the treatment process, the material is pressed for a very short time (less than 0.001s), and the pressure change rate is large, and the pressure can rise to 300MPa. At the same time, two or more microjets in the bullet type (speed can reach 500m/s) pass through the high shear of the diamond cavity in the homogeneous cavity, and then collide with each other after being separated in the diamond Y-shaped channel. During the process, the material is subjected to effects such as collision explosion, high-frequency shear oscillation, cavitation, pressure drop, etc., so that the material achieves nanoscale uniform refinement.【3】
