Mixing of liquids is based on two or more liquid ingredients to a certain degree of uniformity. The amount of time required to mix the ingredients is referred to as mixing duration. It is the time necessary to achieve a certain concentration and ratio of samples taken from one vessel. There are “raw” and “precise” proportions of the mix. The “raw” mix takes about half the estimated mixing duration, while “precise” mix requires twice the time.
Industrial applications of mixing liquids
Mixing of liquids is an important part of consumer goods production. None of the consumer goods industries can do without mixing equipment and processes: perfumery, cosmetics, detergents, food production etc. Oil refining and automotive industry also require mixing of liquids. Even toothpaste is made by mixing a liquid with flavor additives under vacuum until achieving a uniform product.
The mixing process
Both high and low viscosity liquids can be mixed. In the case of low viscosity, the mixing is turbulent (high flow velocity) and does not depend on the shear rate of the liquid. In comparison, mixing of highly viscous liquids requires shear to achieve product uniformity. Such mixing occurs in laminar flow (low flow velocity).
When high and low viscosity liquids are mixed, the latter is used as the base. The high viscosity liquid is added to the low viscosity liquid. Such sequence makes it possible to save electric energy by using smaller equipment. The dyes used in the process serve as indicators, visualizing the homogeneity of the product.
Much depends on the selected equipment. A technology that allows to precisely calculate the ratio of components during mixing is a great success in any industry.
Modern liquid mixing equipment designs make possible high tech equipment for precise quality mixing. Enclosures and parts are made of stainless steel and are resistant to acids. Temperature controls allow to perform exothermic or endothermic processes, while specialized equipment makes it possible to blend highly viscous mixes, suspensions or dispersions.
How does liquid mixing equipment operate?
- Each liquid stream is independently portioned into a mixing chamber with higher rate than the maximum output rate.
- Portioning can be performed in the on/off or programmed mode.
- Ingredients are mixed in precise accordance to the required ratio and simultaneously.
- The liquid blending system is precise and stable, with automatic control the system automatically corrects for deviations.
- The system automatically adapts to changing dosage without recalibration or output flow rate adjustment.
The popularity and benefits of the new systems are obvious. They improve production efficiency and make it possible to develop new products based on custom formulas. Investing into the modern liquid mixing equipment is a good way to save costs and expenses and increase profits.
