The automatic panning provides considerable help in the reduction of production costs. Indeed, since the products are automatically panned, the process is faster and, at the same time, more reliable. The automatic panning can be adjusted also to all common production lines. Several models are available: bridge-type panning, retracting unit, mechanical or pneumatic pannings. The automatic rack loaders are made on specifications of each customer, according to the characteristics of trays and trolleys, and can be connected to other lines and also pre-existing plants. The rack loaders automate the process of loading or unloading, reducing production and labor costs.
