Economy and ecology in harmony through automatic monitoring of the filling line

Industria farmacéutica

For over 60 years, the French brand Yves Rocher has been synonymous with high-quality cosmetics based on vegetable raw materials. The company is strongly committed to ecological issues and biodiversity. Even small factors such as the optimal use of raw materials play a role here. In order to avoid product losses during processing, Yves Rocher relies on automatic level control with the NCS-L level sensor when filling cosmetic cremes. With full success.

Testimonials

"We were not sure whether sensor monitoring could work on this medium with viscosities up to 160 Pa·s. But Anderson-Negele’s NCS -L immediately showed perfect results without adjusting the factory setting. We save time for our employees and have been able to significantly reduce product losses. Based on the positive test results, we will now convert all filling systems to the NCS-L."

— Bernard Massart, Industrial engineering, Groupe ROCHER

The Anderson-Negele solution

Application advantages:

  • Significantly lower product losses due to optimal emptying of the tank during filling
  • Precise measurement results despite high viscosity of the cream and corresponding adherences to the sensor probe
  • No manual control and monitoring required
  • Fast amortization through reduction of product losses and time savings for employees

Detalle de aplicación

The application

The filling systems for cosmetic creams were previously controlled manually. The filling level in the buffer tank had to be monitored by an employee and the filling process had to be stopped manually at the appropriate moment. In order to prevent the filling pump from running dry, the process was stopped for safety reasons at an early stage, leaving important quantities of cream in the tank. This residual product was then disposed of, resulting in a significant loss of value.

The Anderson-Negele solution

With the NCS-L level sensor, the filling process is automated. Due to its special sensor shape with 18 mm length and its measuring method with an extended measuring range, the NCS-L-12/18 is particularly suitable for low-water, viscous media such as oils, syrups or even cosmetic creams. Thanks to its inline integration in the outlet pipe of the filling system, the sensor signals safely and reliably as soon as no more cream comes out of the buffer tank, thus stopping the filling process automatically.

The result:

  • Cream losses are minimized.
  • The quantities of waste to be disposed of (cream remaining in the tank) are reduced.
  • Impurities (splashes due to dry running of the filling pump) are avoided.
  • Maximum process reliability for the personnel operating the filling system.

By level measurement directly in the outlet pipe after the buffer tank, the NCS-L reports a reliable empty signal even with the viscous consistency of the cosmetic cream. Dry running of the pump, resulting in inadequately filled cream pots as well as splashes and contamination of the filling system, can thus be reliably avoided.
