The most ideal processing equipment for fine materials - colloid mill
2021-05-02
China Drying Equipment Co., Ltd.: Colloid mill is driven by the motor through the belt drive drive gear (or called the rotor) and matching fixed teeth (or called the stator) for relative high-speed rotation, one of which rotates at high speed, the other is The processed material is pressurized by its own weight or external pressure (which can be generated by the pump) to generate a downward spiral impact force, which is subjected to strong shear force and friction force when passing through the gap between the fixed and gear teeth (adjustable clearance). High-frequency vibration, high-speed vortex and other physical effects make the material effectively emulsified, dispersed, homogenized and crushed to achieve the effect of ultra-fine material pulverization and emulsification.
Development status:
Colloid mills are widely used in various fields of national economy and people's livelihood. Due to the need to meet the requirements of various working conditions, the variety of colloidal mills is huge. China's colloid mill manufacturing industry is very large. There are thousands of colloid mill manufacturers throughout the country. At present, China has become one of the countries with the largest amount of colloid mill production and market demand in the world.
Most colloidal grinding industries in China are small and medium-sized enterprises. There are less than 10 companies with an annual output value exceeding 100 million yuan. Even if compared with other domestic machinery industries, there is a big gap between equipment and technology. There are very few units that have the capacity to independently research and develop high-end products. Therefore, in the major projects such as large-scale nuclear power, petrochemical, and oil and gas long-distance transmission pipelines, the colloid mills are mainly imported.
development trend:
The theoretical research of colloidal drying technology can be summarized as the low-pressure space, theoretical research of low-temperature heat and mass transfer, and the study of thermal properties and measurement methods. The low-pressure low-temperature heat and mass transfer theory has been studied earlier and the results are relatively obvious. The recognized colloidal grinding models can be summarized into three types: (1) The steady-state model (URIF) of the uniform ice back interface proposed by Sanda11 et al. in 1967. (2) The quasi-steady state model proposed by Dryer et al. in 1968; (3) Adsorption-sublimation model proposed by Litchield et al., 1979.
All of these models can describe the process of colloidal grinding, but they all have their own shortcomings. They describe the heat transfer process is more accurate and describe the error of the mass transfer process. The main problem is that the solid-vapor phase transition occurs during the mass transfer process. The water vapor is transmitted through the porous channel. The length of the channel changes with time and is an unsteady process. The structural dimensions of the porous channels are also related to the pre-freezing speed and the material structure of the colloid milled product. No new breakthroughs have been seen in recent research reports.
Colloid Mill:
1. This Vertical Colloid Mill is multi-functional, it can be used for peanut butter, cocoa butter, sesame butter, chili paste, walnuts, almond butter, dates paste, corn paste, chicken meat paste, corn milk, soybean milk, rice milk, turmeric, mayoonaise, garlic, tomato etc.
2. We have two types peanut butter colloid mill: full stainless steel type and ordinary type(stainless steel with carbon steel). You can choose it freely based on your demands.
A colloid mill is a machine that is used to reduce the particle size of asolidin suspensionin a liquid, or to reduce the droplet size of a liquid suspended in another liquid. Colloid mills work on the rotor-stator principle: a rotor turns at high speeds. The resulting high levels of hydraulic shearapplied to the process liquid disrupt structures in the fluid. Colloid mills are frequently used to increase the stability of suspensions and emulsions., but can also be used to reduce the particle size of solids in suspensions. Higher shear rates lead to smaller droplets, down to approximately which are more resistant to emulsion separation.
We mainly manufacture: meat processing machines, milk processing machines, egg processing machines, fruit vegetable machines etc. We have years of exporting experiences, sincerely hope for copperation!
