Automatic systems for mixing and transporting the raw materials

Automatic Mixing and Conveying Systems for Cereal Cakes and Popped Chips

The quality of cereal cakes and popped chips depends on the correct preparation of raw materials. Before processing, cereals and micropellets must reach the ideal moisture level through controlled mixing to ensure uniform expansion.

Horizontal Mixers for Uniform Preparation

RE PIETRO uses horizontal mixers (3) designed to quickly blend cereals, micropellets, and water.
The mixers can include:
• Load cells for precise and automatic control of raw materials and water;
• Spraying nozzles for a homogeneous distribution of water.

Once mixing is complete, the raw materials rest for the time necessary to fully absorb the water.

Automatic Conveying to RP-EVO Popping Machines

After reaching the optimal moisture level, the product is conveyed to the RP-EVO Popping Machines (5) via a chain conveyor (4).
Pneumatic discharge points can be installed on the conveyor, depending on the number of machines. Sensors in the hoppers of the Popping Machines signal the minimum level to the Master PLC (1), automatically activating the loading process and ensuring continuous operation.

Big-Bag Stations and Full Automation

For high-capacity production lines, big-bag unloading stations (2) can be integrated and connected to the conveying systems to feed the mixers automatically and accurately.

Centralized Control via Master PLC

The Master PLC manages all process stages: mixing, water dosing, operation of the chain conveyor, and feeding of the RP-EVO Popping Machines.
From the control panel, the operator can configure recipes, desired moisture levels, mixing times, and system start/stop.
