Dry fractionation method of beef tallow

The invention discloses a dry fractionation method of beef tallow, and the dry fractionation method of the beef tallow comprises the following steps: degumming raw beef tallow to obtain degummed oil; deacidifying and decolorizing the degummed oil to obtain refined beef tallow; completely melting the refined beef tallow, continuously heating for a first preset time, and rapidly cooling to a first preset temperature; and cooling the refined beef tallow to a first crystallization temperature at a first preset cooling rate, growing crystal at the first crystallization temperature for a second preset time, and filtering to respectively obtain a liquid grease product and a solid grease product. 本发明公开一种牛油的干法分提方法，所述牛油的干法分提方法包括：对毛牛油进行脱胶，得到脱胶油；对所述脱胶油脱酸、脱色处理，得到精炼牛油；将所述精炼牛油完全熔化后继续加热第一预设时长，并快速冷却降温到第一预设温度；将所述精炼牛油以第一预设冷却速率冷却至第一结晶温度，在所述第一结晶温度下养晶第二预设时长，过滤分别得到液体和固体油脂产品。
