The diagram illustrates the process by which olive oil is produced. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
The provided text outlines the multi-stage process involved in the production of olive oil, from the initial harvesting of olives to the final packaging. The overall process can be broadly divided into preparation, extraction, and refinement stages. Initially, harvested olives undergo a cleaning phase where leaves, twigs, and dirt are removed, followed by a thorough washing. Subsequently, these clean olives are crushed to form a paste. This paste then enters the malaxation stage, a crucial step involving slow stirring for 20-40 minutes to allow oil droplets to merge, facilitating easier separation. Following malaxation, the oil is extracted from the paste using centrifugation, a method that separates the oil from solid and liquid waste through high-speed spinning. The final stage involves filtration to eliminate any residual impurities, resulting in a clear, refined olive oil. This finished product is then prepared for sale.
