Animal fats and oils are a general term for a class of substances, including natural animal fats or oils from organs on the body of animals, as well as oils contained in certain minerals. They are the most widely used instant ingredients for butter. I believe many The foodies know that the cream is divided into animal cream and vegetable cream. Many of the animal creams are not extracted from the body or extracted from milk. They are chemically synthesized, so we use the animal fats we say.
There are many ways to separate animal oils. There are melting point separation methods: separation of animal fats mainly according to the melting point of different substances. Some materials contain only oil and water. The easiest way is to evaporate at high temperature. There are many other ways. The acid decomposition method, and the separation of many chemical agents, and the other is the precipitation separation, which is relatively primitive and the separation effect cannot be guaranteed.
Many separation steps involving oil production are mainly carried out by means of a dedicated centrifuge. The separator uses high-speed rotation to perfectly separate materials of different quality and medium. Can avoid waste and incomplete separation. This kind of industrial separation equipment is generally manufactured by a professional separator factory. There are also some manufacturers that are not specialized in the production of centrifuges. The use of the separators is uneven, and the purchase needs to be confidently identified.
Centrifuge manufacturers are more domestic, and most of their products are similar. The reason is that China is a common phenomenon, that is, “cottageâ€. Most of the cottages are old-fashioned manufacturers in the early days of New China (such as "Liaoning Fuyi", etc.), or famous foreign manufacturers (such as certain German enterprises, Japanese companies, etc.). Therefore, it is advisable for the old-fashioned manufacturers to choose the procurement. If the budget is sufficient, the imported centrifuges can also be considered.
