Description
Technical field
The invention belongs to soybean oil preparing technical fields, and in particular to a kind of method that microwave prepares soybean oil.
Background technology
Soybean oil generally with the more crude oil of impurity is obtained after a variety of method processing such as squeezing method and lixiviation process, then passes through
Refining obtains edible refined oil.Squeezing method is divided into as two kinds of plain press method and screw press method.Plain press method is one
The method that kind is pressurizeed on soy.This method does not use very much, does not almost have in industrialization large-scale production especially.Spiral
Squeezing method is to be equipped with helical axis in the cylinder of horizontal device, after pretreated soybean enters pressafiner;On one side
Advance on one side squeezes out grease.This method can be with continuous production, but during oil expression, because of frictional heating, protein
It mostly occurs and largely changes.Leaching refining method be using the solvent of grease can be dissolved, by soak infiltration, molecule diffusion and
Grease in material base is leached out by the effect of Convention diffusion.Then, the miscella that solvent and fat are formed is divided
Crude oil is obtained from, recycling design.There are hexane or light vapour using most common leaching solvent in China's oils preparation industry actual production
Several aliphatic hydrocarbons such as oil.Wherein light petrol be using a kind of most solvents, but it is maximum the disadvantage is that dosage it is big,
Inflammable and explosive, complicated component therefore a large amount of down-streams are needed to control the level of the dissolvent residual in finished product;And it uses general
Squeezing method does not reach very high level for the recovery rate of soybean oil, and that there are soybean oil recovery rates is relatively poor, soybean oil is sharp
With the problem that rate is inadequate.
