The stainless - steel emulsifying mixing tank for shampoo production is a crucial piece of equipment in the shampoo - making process. It is typically made of high - quality 316L or 304 stainless steel, which endows it with outstanding corrosion resistance and hygienic properties, ensuring that the tank can withstand various chemical substances in shampoo production without contaminating the products.
The tank usually has a vertical cylindrical shape and comes in a wide range of volumes, commonly from 50L to 5000L, to meet different production scale requirements. The mixing device consists of a mixing shaft and various types of mixing blades. The mixing shaft, driven by a high - power motor through a reducer, rotates stably. The mixing blades, such as turbine - type, anchor - type, and helical - ribbon - type, are selected according to the characteristics of the shampoo raw materials. For example, turbine - type blades are great for creating strong shear forces, which are essential for emulsifying the oil - phase and water - phase materials in shampoo production.
An essential part of the emulsifying mixing tank is the emulsifying device. High - speed homogenizers are often used, which work by a high - speed rotating rotor and stator. The high - shear force generated by them can break down the oil and water phases into tiny particles and mix them evenly, resulting in a fine - textured and stable shampoo emulsion. Some tanks are also equipped with colloid mills to further refine the material particles and enhance the emulsification effect.
The heating and cooling system is another key component. During shampoo production, precise temperature control is necessary. The heating system can use electric heating, steam heating, or heat - conducting oil heating methods to raise the temperature of the materials, promoting the dissolution and reaction of the raw materials. The cooling system, usually achieved through circulating cooling water, can prevent the materials from overheating, ensuring the quality and performance of the shampoo.
To ensure the tightness of the tank and prevent material leakage and external impurity entry, a high - performance sealing system is installed. Mechanical seals are widely used, especially double - end face mechanical seals in some high - requirement production scenarios, which can maintain excellent sealing performance under high - speed stirring and high - pressure conditions.
In addition, the emulsifying mixing tank is equipped with various accessories. Liquid level gauges are used to monitor the liquid level of the materials in the tank in real - time; thermometers and pressure gauges can measure the temperature and pressure of the materials, providing important data for the production process; safety valves can automatically relieve pressure when the pressure in the tank is too high, ensuring the safety of the equipment; CIP cleaning ports are used to connect to the cleaning system for automatic cleaning of the tank, maintaining high - level hygiene; sight glasses and manholes facilitate operators to observe the internal situation of the tank and carry out equipment maintenance.
