RE PIETRO SRL designs and delivers complete productions lines, from the processing machines to the packaging line, and offers an efficient after-sale service.
Automatic systems for mixing and transporting the raw materials
The raw materials to be used for the production of puffed cakes or popped chips need to be moistened before processing, to increase their inner humidity to allow the correct expansion.
Occasionally, if you use micro-pellets for the production of popped chips, it may be necessary to use a minimum quantity of lecithin to prevent the sticking to the molds.
To carry out this process automatically, Re Pietro s.r.l. uses horizontal mixers (3) that can perfectly mix the products in a few minutes.
The mixers can be installed on loading cells able to measure the correct quantity of raw material to be loaded, and they can have nozzles to spray water to ensure a perfect and homogeneous distribution of the water on the raw material.
Once the raw materials have been mixed and the necessary time to moisten the cereals has passed, the raw material is delivered to the Popping Machine (5) through the chain transport system (4) where the pneumatic discharge points have been positioned, based on the number of the popping machine installed on the production line.
When the level of the raw material is low inside the hopper, the sensors that are located in the hopper of the Popping Machine send a message to the PLC Master which will automatically guarantee the continuous feeding of the raw material to the popping machines.
It is also possible to install in the plant the big bag discharge systems (2) connected to an automatic transport system that will automatically deliver the correct amount of raw material to the mixers to start the moistening and the production.
The whole process is controlled by the main electrical panel (1) and it is managed by the Master PLC through which you can set the recipes, set the necessary percentages of water to add to reach the proper humidity of the raw material, set the mixing times, the transport to the Popping Machine, the start and stop of the plant.
