Nano sand grinding technology reshapes the new ecology of dairy raw material processing

Technological Innovation: Preparation of Dry Grinding Dairy Raw Materials
Traditional wet grinding relies on liquid-phase media, which can easily cause solvent residue and thermal sensitive component damage. The new generation of dry powder sand mills innovatively adopts the principle of gas-solid fluidized bed grinding. By using high-speed airflow to drive the powder to collide violently with nanoscale grinding media, ultrafine grinding and synchronous modification can be achieved in a closed environment. The vertical sand mill is equipped with a convex pin turbine rotor structure, which significantly improves the energy density compared to traditional equipment, and the particle group is efficiently "torn" into micro fluidized units. This technology is particularly suitable for the processing of active raw materials such as probiotic preparations and whey protein powder, avoiding the risk of bacterial inactivation in the wet drying process
Wet precision research: sterile environment ensures pure quality of dairy products
The fully enclosed horizontal sand grinder demonstrates advantages for high viscosity materials such as yogurt base milk and chocolate milk slurry. The equipment adopts double end mechanical seal technology to solve the leakage problem and prevent the material from coming into contact with air to form a dry solidified skin. The German imported grinding disc drives zirconia beads with a spiral trajectory, and completes the homogenization of milk fat particles under the guarantee of a low-temperature circulating water system, making the finished product taste more mellow and dense. The application case of a certain dairy company confirms that this process can improve the uniformity of milk protein particle size distribution and effectively solve the problem of sedimentation and layering in dairy beverages
Industry Empowerment: Health Demands Drive the Wave of Equipment Upgrades
With the surge in consumer demand for "clean labels", sanding equipment is accelerating its iteration towards pollution-free direction. The latest model integrates a in-situ cleaning system (CIP) and a hydrogen peroxide atomization sterilization module to ensure that the chamber cleanliness meets pharmaceutical standards. Modular design supports quick switching of grinding media, and a single device can alternately process cocoa butter particles and functional calcium fortified milk powder. The leading enterprises have launched laboratory grade micro sand mills to meet the needs of new formula hundred gram small-scale trials, shortening the research and development cycle.
