PRE-PRESSING/ FULL PRESSING
In connection with the supply of solvent extraction plants and oil refinery, CMBITALY – TECHNOILOGY – when required – supplies pressing plants for pre-pressing or full pressing. Presses are selected from the qualified suppliers available on the market in accordance with the raw material and product characteristics.
Pre-pressing is especially designed for large capacities. It is used to process seeds having a high oil content and which need to be partially pressed before being de-oiled by solvent extraction. This process is completed with a system to filtrate or centrifuge oil before sending it to storage.
