In recent years, the commodity economy has developed rapidly, and the high-shear vacuum emulsifier has been widely used, which has created huge economic benefits for many enterprises. In particular, the equipment is simple and flexible to operate, has multiple functions, and has good effects, which is well received by users.
High-speed emulsification starts with forward mixing and reverse mixing starts with low mixing. The front blade conveys the material upward, and the rear blade conveys the material downward. According to the application of the mixing unit, customers can choose a variety of high-speed vacuum emulsification units according to the working capacity and speed. The material is continuously loaded and mixed under the action of these two opposing forces, and is thrown to the middle under the action of centrifugal force. Repeat this process until the material is completely mixed, dispersed and homogenized. After that, the heat of the coating is quickly transferred to the various parts through the inner wall.
The vacuum emulsifier is controlled by PLC touch screen. The lid can be lifted, poured and drained. The bottom of the pot can also be drained. Easy to clean. The material can be heated by heating the thermally conductive medium in the crucible interlayer by an electric heating tube. The heating temperature can be set arbitrarily and automatically controlled. The material can be cooled by adding a coolant to the intermediate layer. The operation is simple and convenient. There is a thermal insulation device outside the middle layer, and the homogenization system and the mixing system can be used separately or simultaneously. The granulation, emulsification, mixing, homogenization and dispersion of materials can be completed in a short time.
The working principle of the high shear homogeneous emulsifier is very simple. The motor drives the shaft of the stirring tank. The shaft is connected with the impeller, the impeller rotates at a high speed, and the material is driven into the mixing tank by its strong centrifugal force. It is necessary to introduce the components into the agitation tank in a variable-speed manner, as some stages of the agitation process do not require vigorous agitation.
The stability of the emulsion produced by the emulsifier is related to the raw material characteristics, operating characteristics and mechanical characteristics during the preparation process. The raw material characteristics include the type of raw materials, the soft water of the raw materials, and the feeding sequence of the raw materials. The operating characteristics include adding and mixing raw materials. method, emulsification temperature, emulsification time, and mechanical properties include the type of emulsification device, the stirring speed of the device, and the shape and diameter of the stirring rotating blade. Pre-emulsion is relatively more stable, but requires longer emulsification time.
