Weighing and Dosing of IBC Container

Intro:

We developed a fully automated system designed for accurately weighing and dosing cleaning solutions used in industrial processes for washing tanks containing glucose, chocolate, and other ingredients used in food production. The project is built for maximum precision, full traceability, and high operational efficiency.

Project Description

The system uses one or two IBC containers placed on a stainless-steel platform equipped with four high-precision load cells. The operator positions the container using a forklift, and the platform continuously transmits the measured weight to the PLC.

On the HMI interface, the operator sets:

• solution type,
• IBC container code,
• required consumption per washing cycle,
• initial weight.

Based on these values, the system automatically calculates the total amount of solution available in the container and the actual consumption per cycle.

To ensure process quality, a higher-level authorized operator can configure the maximum allowed hysteresis (tolerance). For example: if a cycle normally consumes 10 kg and the hysteresis is ±2 kg, any value between 8 and 12 kg is acceptable. When consumption goes outside this range, the system triggers visual and audible alarms.

The HMI also displays date, time, and allows saving all process data onto an external USB drive (only accessible to authorized factory personnel). The system also receives an external Start Wash signal from the associated industrial washing equipment.
