SITASA unloads, stores and sells agricultural produce for major national and international importers in the port of Tarragona, Spain. SITASA guarantees its customers a high degree of precision – with the precise and reliable weighing solutions from METTLER TOLEDO.
Weight is a crucial factor for SITASA: It is vital that precisely the volumes unloaded and stored are then delivered. As SITASA has to bear any costs for losses or weight deviations.SITASA’s clients commission it to store goods and subsequently distribute them to their customers. Understandably, the control system for incoming and outgoing goods must be highly reliable and accurate. SITASA therefore opted for the highest precision from METTLER TOLEDO.
The set-up for receipt of goods of SITASA consists of three vertical hoppers.
- The first hopper is considered to be the ‘lung’, and its capacity is three times that of the second. Its main function is to store the cargo that is being unloaded from the ship.
- The second (central) hopper is where the weighing takes place. It is fitted with four METTLER TOLEDO load cells, hung from a rack in the structure. The central
hopper is filled by bulk flow from the first hopper, the weight is left to stabilize, the cargo is weighed in batches of 8500 kg and unloaded in bulk into the lower hopper. - The capacity of the third hopper, which is located beneath the first two, is 1.2 times that of the second hopper. This is where the flow of the goods is adapted to the nominal capacity of the facility and sent to the silos.
The information from the load cells is sent to the METTLER TOLEDO process weighing
terminal located in the control area, which stores and checks all incoming material, to guarantee the accuracy of the subsequent distributions.
