Traditional Chinese oil extraction

The traditional Chinese oil pressing method mainly includes the following steps: Raw Material Processing: Select high-quality oilseed crops such as sesame, rapeseed, peanuts, etc. Process them by dehulling, crushing, and steaming to achieve the suitable state for oil pressing. Grinding: Place the processed oilseeds into a stone mill for grinding, reducing them to fine powder to facilitate the subsequent oil pressing process. Steaming the Embryo: Mix the finely ground oilseeds with water to form an embryo, then steam it in a steamer to cook, inducing denaturation of proteins in the oilseeds, which aids in oil separation. Forming Cakes: Take out the steamed embryo and wrap it with grass or cloth into round cakes, preparing for the subsequent pressing process. Pressing: Place the wrapped embryo cakes into an oil press for pressing, using physical pressure to separate the oil from the oilseeds. Traditional oil presses mainly include wooden presses and iron presses, both requiring manual or animal power to operate. Precipitation and Filtration: Let the pressed crude oil settle and filter it to remove impurities and suspended particles, obtaining pure vegetable oil. It's important to note that while traditional oil pressing methods have advantages such as being natural and healthy, they come with low production efficiency, requiring substantial manual labor and time. Additionally, traditional oil pressing processes may pose hygiene and safety concerns that need to be addressed. The above outlines the general steps of the traditional Chinese oil pressing method, and specific details may vary depending on the region and the type of oilseed crops used. #china 中国传统榨油方法主要包括以下几个步骤： 原料处理：选取优质的油料作物，如芝麻、菜籽、花生等，进行去壳、破碎、蒸炒等处理，使其达到适宜的榨油状态。 碾磨：将处理好的油料作物放入石磨中进行碾磨，将其磨成细粉，有利于后续的榨油过程。 蒸胚：将碾磨好的油料细粉加水搅拌成胚，然后放入蒸锅中蒸熟，使油料中的蛋白质变性，有利于油脂的分离。 包饼：将蒸熟的胚取出，用草料或布料包裹成圆饼状，以便后续的压榨过程。 压榨：将包好的胚饼放入榨油机中进行压榨，通过物理压榨的方式将油料中的油脂分离出来。传统榨油机主要有木榨和铁榨两种，都需要人力或畜力进行驱动。 沉淀过滤：将榨出的毛油进行沉淀和过滤，去除其中的杂质和悬浮物，得到纯净的植物油。 需要注意的是，传统榨油方法虽然具有天然、健康等优点，但生产效率较低，需要大量的人工操作和时间成本。同时，传统榨油过程中也存在一些卫生和安全问题，需要注意防范。 以上是中国传统榨油方法的大致步骤，具体细节可能因地区和油料作物的不同而有所差异。 来源：抖音“宣城狼哥”
