The Role of High Shear Emulsion Machine in Ice Cream Production
Release time:
2022-03-28
The production process of ice cream is: raw material selection → mixing according to formula → sterilization → homogenization → cooling → ripening → freezing → packaging → quick freezing and hardening → cold storage. Ice cream is milk or dairy products as the main raw material, high-shear emulsifying machine to add eggs or egg products, sucrose, emulsifier, stabilizer and spices, after mixing, homogenization, sterilization, maturation, freezing, molding, hardening and other processes into a nutritious frozen food.

After the mixture is sterilized at low temperature, a homogenizing emulsifier (High shear emulsifying machine) Rapid homogenization. The purpose of homogenization is to micronize the fat globules in the mixture, prevent the formation of a cream layer, fully mix the ingredients, increase the viscosity of the mixture, help increase the expansion rate, improve the texture of ice cream, shorten the ripening time, and save emulsifiers And thickeners, effectively prevent the formation of cream particles during freezing. The homogenization temperature is 60-63°C. After the mixture is homogenized, the viscosity increases, which can improve the expansion rate, lubricate the tissue, and prevent fat separation. In addition, the digestibility of fat is also good, the stability of the finished product is increased, and it is not easy to melt.
The purpose of homogeneous emulsification of the high-shear emulsifier is to put the mature mixture into the mixing tank of the refrigerator and freeze it under strong stirring, so that the air is evenly distributed in all the mixtures in the state of very small bubbles, and a part of the water becomes Fine crystals. The high-shear emulsifying machine has three interchangeable stators of mesh, long hole and round hole, which are suitable for shearing, crushing, dispersing and emulsifying various materials. The stator gap is small, and a narrow particle size distribution can be obtained by using a mesh stator. There are one-way and two-way suction forms, as well as arc blade rotors, which can meet more working conditions.
High shear emulsifying machineIt is also an emulsifying equipment. Its working principle is that the centrifugal force generated by the fast-running rotor of the equipment causes the material to be sucked into the working cavity from the feed area of the working head from the axial direction at the same time, and the material is subjected to centrifugal extrusion, impact and other forces, so that the material is initially effective Dispersion and emulsification.
