原料经过叶片（或袋式）过滤器过滤去除机械杂质后使用中压或高压水解法 将

After the raw materials are filtered through leaf (or bag) filters to remove mechanical impurities, they are completely hydrolyzed into fatty acids by medium pressure or high pressure hydrolysis (AV≥180mgKOH/g) for heating vacuum dehydration and fine filtration.

After the raw material is filtered through the blade (or bag) filter to remove mechanical impurities, it is completely hydrolysed into fatty acids using medium pressure or high pressure hydrolysing (AV-180mg KOH/g) for warm vacuum dehydration and fine filtration.

The raw materials were filtered by leaf (or bag) filter to remove mechanical impurities, and then they were completely hydrolyzed into fatty acids by medium pressure or high pressure hydrolysis method, and then heated vacuum dehydration and fine filtration were carried out after AV ≥ 180mgkoh / g.
