It needs to dewaxing in some of vegetable oil refinery equipment, such as sunflower seeds.Common processing method of dewaxing oil refining equipment for the cooling crystallization separation process, so in addition to this method, there is no other dewaxing method?Henan huatai cereals and oils machinery co., LTD. has an introduction to several common dewaxing oil refining equipment.

1. Regular dewaxing methods: conventional method including dewaxing alone freezing crystallization, and then use the mechanical method to separate oil, wax and without any auxiliary agent and dewaxing method of auxiliary means.Separation by pressure filtration, vacuum filtering and centrifugal separation equipment.
2. The solvent method: solvent method is to use the auxiliary solvent waxy precipitation separation, dewaxing, at the same time, the conventional method to join dewaxing solvent from wax and oil content of oils and fats faster and more convenient.
3. The surfactant method: surfactant is using has good affinity of surfactant with wax, accelerate and support the formation of wax crystallization, so as to achieve better effect of dewaxing method.
4. Degumming, deacidifying, dewaxing synthetic method: this method is in the process of acid and degumming, join dewaxing link, can save the production cycle, but for the oil refining equipment treatment effect is not very high,
so less commonly used.Soapstock compositions isolated complex, is not conducive to further use, this also is a bad place.
Basically common oil dewaxing method is that several refining equipment, comprehensive consideration, conventional dewaxing method is the best choice, so the general oil refining equipment will be using the conventional
dewaxing method, unless there is a special case, will choose other more suitable way of dewaxing.
