The definition of vacuum emulsifier refers to that under the vacuum and oxygen free state, the materials are quickly and evenly distributed into another continuous phase by using a high-speed high shear emulsifier. With the powerful kinetic energy brought by the motor, the materials are subjected to high frequency hydraulic shearing, centrifugal extrusion, impact and other comprehensive effects in a single position time in the space where the stator and rotor are fixed, and the emulsification is uniformly dispersed in an instant, through high-frequency cycling, Zui finally gets high-quality products without bubbles, fine and stable.
Definition of high shear emulsification machine: a machine that can fully refine and even the materials. Generally speaking, it is a machine that can shear and stir the materials for emulsification. There are many kinds of machines for uniform refinement, such as ball mill, sand (bead) mill, crusher, colloid mill, disperser and high-pressure homogenizer. These machines can refine materials with different application scope and capability. The high shear emulsifier has the functions of thinning, dispersion and homogenization. It is mainly used for liquid-liquid emulsion homogenization, liquid-solid (powder, small particles) refinement and dispersion. It is suitable for working under normal pressure, vacuum and positive pressure. It features stable operation, low noise, convenient cleaning, flexibility, continuous use, and ultra-fine dispersion and emulsification of materials.
Structure of vacuum emulsification machine: the vacuum emulsification machine is mainly composed of pretreatment pot, main pot, vacuum pump, hydraulic pressure, electrical control system, etc. The materials in the water and oil pans are fully dissolved and then sucked into the main pot by vacuum for mixing and homogenizing emulsification.
High shear emulsification machine: it can be divided into one-way and two-way working modes in terms of material suction mode; From the layout mode, it can be divided into radial flow and axial flow working modes; From the rotor structure, it can be divided into slotted ring type, closed slotted ring type, four straight blade rotor, three curved blade rotor and multi-layer open (closed) slot ring type; From the stator structure, it can be divided into straight groove open type, straight groove closed type, inclined groove open type, inclined groove closed type, mesh, round hole and multi-layer; According to the working sealing requirements, it can be divided into open (hanging, kettle mounted) and sealed emulsifying machines (mechanical seal, water seal, oil seal, magnetic drive seal)
