Water Injection Automation in Coffee Production

M-Sens 2
SCHLIENGEN - The food industry is in constant revolution when the subject is measurement. Controlling exact amounts of condiments, spices and all sort of ingredients is direct related to important quality factors like consistency, flavour and due period.

Monitoring moisture with M-Sens 2

Coffee is a daily drink for a lot of people, it means people can notice quickly small changes in the flavour. During the manufacturing process coffee should be roasted in specific temperature ranges and it is directly connected to the moisture content. One of our customers asked for a measurement system to monitor moisture after the final roaster.

In that part of the process, it is essential to keep characteristics good enough to conveying till the packing sector and deliver with the taste that everyone appreciates.

Process data

  • Customer: Coffee producer
  • Product: Coffee grains
  • Moisture range: 3,5 – 5 %
  • Installation: Slide after final roaster
  • Function: Control water injection into the roaster

The solution

M-Sens 2 – Application

The M-Sens 2 measures continuously up to 65 % of moisture content in materials conveyed on different devices as screw feeders, conveyor belts, slides and more. In the described application measuring the moisture makes possible to determine when and how much water should be injected into the final coffee roaster. After the automatic control, the manufacturing process became more reliable, thanks to online measurement which makes sure that as soon the moisture content changes the new set point for the water injection lines is sent.

Customer benefit

  • Online control of the water injection
  • Avoidance of missing moisture changes
  • Measurement through the beans
