Shanghai Shenlu Homogenizer Co., Ltd.: The role and characteristics of high shear homogenizer
Time:2022-04-15 12:06
Shanghai Shenlu Homogenizer Co., Ltd.It is believed that in industry, when two immiscible liquids or solid-liquid inclusions are mixed, an emulsifying machine is usually used to complete the oil-water emulsification to achieve the purpose of dispersion and homogeneity. The main force of the high shear homogenizer is the shear force. When the oil-water two-phase medium is mixed to form a water-in-oil or oil-in-water mixture, it cannot exist stably. A suitable emulsifier is required to increase the surface tension of the system. In the process of homogenization treatment, the medium is broken into fine particles by strong cutting and dispersion, forming a stable and uniform dispersion system, and achieving a good emulsification effect. At present, the application of homogeneous emulsifiers is not limited to emulsification. Shanghai Shenlu Homogenizer Co., Ltd. believes that the emulsifier has a strong shearing effect, which can break the powder particles into fine particle size under the impact of destruction, and then make the solid particles fully mixed into the liquid to form a relatively constant suspension. When the fineness of the material reaches micron or even nanometer, the system can be considered uniform.
Shanghai Shenlu Homogenizer Co., Ltd. believes that the shear head of a high-shear homogenizer is composed of a rotor and a stator that mesh with each other, and each level of stator and rotor has several layers of ring gear. The high-speed rotation of the rotor generates a strong centrifugal force and forms a strong negative pressure zone. The material is sucked into the working chamber, and is subjected to the combined effects of shear, centrifugal extrusion, impact tearing and turbulence in the gap between the stator and the rotor, thereby generating the tension of the split droplets. After the liquid leaves the stator orifice, the pressure rises again, creating a cavitation effect. The homogenizing head rotates at high speed to shear, disperse and impact the material. In this way, the material will become more delicate and uniform. Shanghai Shenlu Homogenizer Co., Ltd. believes that the high-shear emulsifier mainly relies on the high-shear effect generated by the relatively high-speed movement between the stator and the rotor to shear, tear and mix the materials, while the strong cavitation effect disperses, refines and homogenizes the material particles. Its advantages are large processing volume, good product stability, not easy to destroy milk stratification, durable machine, easy maintenance, and richer homogeneous forms.
Shanghai Shenlu Homogenizer Co., Ltd.It is considered that the high shear homogenizer is more suitable for the processing of granular materials with more fibers or harder, and the mixing, sterilization and homogenization can be completed at the same time. The use of high-shear emulsification technology to treat soybean protein greatly reduces protein particles and exposes hydrophobic groups, which is conducive to the formation of gel network and can significantly improve the gel water holding capacity of soybean protein isolate. Using high-speed shear emulsification technology to change the physical properties of corn gluten meal can significantly reduce particle size, improve rheological and solubility, increase starch degradation rate and protein hydrolysis degree, and effectively suppress fruit and vegetable juice stratification. High shear homogenizer is widely used in products with high viscosity and high emulsification requirements, such as soy sauce and fruit tea.
Shanghai Shenlu Homogenizer Co., Ltd.It is considered that the high shear emulsifying homogenizer is a widely used mixing and stirring equipment. Due to the flexibility, ease of operation and high cost performance of high shear homogenizers, the market demand for high shear homogenizers is increasing. With the rise of market demand, many homogenizer manufacturers are competing to develop and produce homogenizing equipment to meet market demand.
