流程图与被动语态

咖啡制做过程中，制作者不重要，动作重要。
The process starts from harvesting the coffee beans from trees. These beans then spread in the filed where they are dried under the sun. The dried beans are subsequently roasted in an oven. At this point, the roasted beans are cooled in a cooler before being ground. The ground beans are mixed with hot water to form a mixture which is strained and further frozen in a freezer. Next, the frozen liquid is ground in a grinder before being dried up in a vacuum so that water evaporates. In the final stage, the processed coffee is packed into jars for sale.
