Curd Watch by Numcore Ltd is a solution designed to ensure accurate cheese block formation by homogenizing curd mass-flow, reducing product loss by up to 30% through even distribution of curd grains. The system features a pipe sensor that tracks the flow of whey and curd in real-time, facilitating precise control over the production process. Numcore offers a trial service with rental of the sensor, providing measurement services and improvement suggestions.

2. Curd Watch
Simple solution for accurate cheese block formation
Without Curd Watch
Different size curd grains unevenly distributed into cheese moulds
Unequal size
cheese blocks
With Curd Watch
Different size curd grains evenly distributed into cheese moulds
Equal size
cheese blocks

3. Accurate cheese blocks are formed
By homogenizing curd mass-flow
Curd mass-flow [kg/s] = The amount of curd in the pipe [kg/m] * Speed [m/s]

4. Screen data
Curd Watch uses a pipe sensor that is easily installed into a process pipe. Curd
Watch shows, how the whey (yellow) and the curd mass (red) flow through the pipe
and forms an index [kg/m] of the curd mass-flow.

5. Why Curd Watch benefits your business
• With Curd Watch:
• Decrease product loss up to 30 percent
• Due to:
• Production of equal weighted cheese
blocks
• Homogenization of the cheese mass
through the whole process
• This is done by:
• Accurately controlling the curd mass-flow
by adjusting the mixer and the pump

11. Elements of Curd Watch solution
Pipe sensor, control unit, software
• The pipe sensor is installed into the process pipe and it collects the
measuring data by using its electrodes
• Control unit activates the sensor by pulsing, processes the measuring data
received from the pipe sensor and transfers the processed data to the
software
• Computer software performs the calculations and converts the information
into a visible form

12. Pipe sensor
