The first step after roasting and destoning is weighing. The coffee needs to be weighed to check what shrinkage occurred during the roasting phase, normally done with a batch weighing system. After that, the coffee must be sent to the storaging silos and there are different solutions for handling this phase.
In the whole coffee processing, the roasted coffee handling and conveying systems represent very important steps to ensure the preservation of the product and its quality.
Roasted coffee can be handled pneumatically or mechanically, which is better depending on the plant capacity/h and the distance from the connected equipment, such as receiving cyclones and rotary distributors above the storaging silos.
The attention to the product preservation is maximum.
Pertoncini TPA system® is a pneumatic trasport in aspiration especially developed for handle the roasted coffee. It has a great flexibility of application, such as elbows, inclined pipes, the option of fixing it to the ground or to the ceiling, multiple discharges and 2-way valves. That means different routes can be installed inside the production area, bypassing any constraints even where there is an existing production complex. Petroncini has developed the TPA system® which guarantees pneumatic product handling for up to 60 m of suction pipes. This system definitely requires less maintenance than mechanical conveyors, avoiding almost all breakage or at least reducing it to a negligible percentage while preserving the aroma.
