Solutions for flavor and color metering in the confectionery industry

Metering flavors and colors is a key aspect of preparing confectionery products. Correctly metering flavors and colors ensures that products meet quality regulations as well as customers’ expectations.

In some manufacturing phases, confectioners need to increase or decrease the injection of these flavors and colors in order to optimize the speed of candy molding without compromising the finished product’s quality. LEWA pump pistons are equipped with speed and stroke adapters to guarantee a range of flow options and high responsiveness. The system can inject "natural" flavors and colors even with the presence of particles and residues.

LEWA’s hygienic food processing solutions

LEWA creates custom-made, complete solutions that are ready to implement in your applications. Accurately metering flavors and colors, in proportion to the flow of acid and gelatin, is crucial to ensure the quality and compliance of your finished products.

Our services range from supplying individual metering units to completely engineering and commissioning injection, mixing, and control systems for batch preparation of products using molding machines, as well as interfaces for existing process control systems. The implementation includes the analysis and application of CE/ATEX 2014/34/EU regulations for potentially flammable products.

The integrity of each process, as well as reliable products and formulas that comply with regulations are core requirements in food technology. Easy cleaning and hygienic aspects are key: each process must remain closed. In every phase of production, manufacturers must avoid the contamination of process fluids.

LEWA supplies precise system solutions that are tailored to the food and beverage industries’ homogenization, mixing, and filling processes.
