The high-pressure manual homogenizer is mainly composed of a high-pressure homogenizer chamber and a supercharging mechanism. The interior of the high-pressure manual homogenizer has a specially designed geometric shape. Under the action of the supercharging mechanism, the high-pressure solution quickly passes through the homogenizing chamber, and the material will be affected by the mechanical forces and corresponding thermal effects such as high-speed shearing, high-frequency vibration, hole phenomenon and convection impact at the same time. The resulting mechanical and chemical effects can induce the physical, chemical and structural properties of the material macromolecules The quality changes, and finally reaches the effect of homogenization.

The high-pressure manual homogenizer uses the high-pressure reciprocating pump as the power transmission and material transmission mechanism to deliver materials to the working valve part. In the process of material passing through the working valve, strong shear, impact and cavitation are produced under high pressure. In this way, the liquid material or the solid particles with liquid as the carrier can be superfine. The manual homogenizer is widely used in the production, scientific research and technological development of food, dairy, beverage, pharmacy, fine chemical industry and biotechnology.

The Core Part Of The High Pressure Manual Homogenizer Is the High Pressure Homogenizer Chamber

The core component of the high pressure manual homogenizer is the high pressure homogenizer chamber, which is the main factor determining the homogenization efficiency. Different internal structure of the high-pressure homogenization cavity, its scope of use and homogenization effect are different.

Generally speaking, the price of equipment using the first generation homogeneous cavity is lower, but the homogeneity performance is not as good as that of the second generation. Using the second generation of homogenization chamber equipment, the homogenization effect of the emulsion is excellent, but when dealing with high concentration and high viscosity materials, it is easier to block than the first generation of products, and the price is relatively high. Therefore, the final choice should be determined according to product demand and overall cost performance. In general, the higher homogeneous pressure is, the better. First of all, the higher the homogenization pressure, the smaller and more uniform the particle size of the homogenized material. This makes the equipment more efficient and can achieve the desired effect through fewer cycles; secondly, the higher the homogenization pressure, the more kinds of materials can be processed. For example, some liquid emulsions only need to be homogenized to below 100nm at 20000psi, while some suspensions with higher density solid particles need to be treated to nanometer level at least at 26000psi.

But at the same time, it should be noted that the higher the homogenization pressure is, the greater the calorific value is. High temperature will affect the homogenization efficiency of materials. Therefore, in general, 30000 psi is the maximum pressure of ultra-high pressure homogenization without cooling measures. The homogeneity function tests the homogeneity of the material. When it reaches the required particle size, its particle size distribution should be centralized, and the particle size distribution should not be the same from dozens of nanometers to several microns, especially the content of large particles of the material after homogeneity. For example, the United States Pharmacopoeia has made clear regulations on the distribution of large particles in medical emulsions.
