Abstract
The invention discloses an extraction technology for cottonseed oil. The technology comprises the following steps: pre-pressing cotton seeds into crude cotton oil or leaching the cotton seeds to obtain the crude cotton oil; filtering; conducting alkali refining and deacidifying; conducting high temperature dehydration at a vacuum condition and then conducting exsolution; conducing refining to obtain the cottonseed oil. The novel refining method of the cottonseed oil is simple and convenient in technology; through the adoption of the novel refining method, the exsolution can be effectively achieved to allow the colour and lustre of grease to be at a relatively-low level, so that the quality and the usability of the grease are improved, the manufacturing cost is greatly lowered, and the refining consumption of the cottonseed oil is lowered. Therefore, the extraction technology is suitable for large-scale industrialized production.
Description
Technical field
The present invention relates to a kind of extraction process of Oleum Gossypii semen.
Background technology
Oleum Gossypii semen method for refining complex process of the prior art, and the precipitation effect is undesirable, and the quality and the use properties that change grease are bad, have greatly improved production cost, have improved Oleum Gossypii semen refining refining consumption rate, are unsuitable for large-scale industrial production.
Summary of the invention
Goal of the invention: the present invention is directed to deficiency, propose a kind of simple process, the extraction process of the Oleum Gossypii semen that can reduce production costs.
Technical scheme: the extraction process of a kind of Oleum Gossypii semen of the present invention comprises the steps:
(1) cottonseed pressed in advance to cotton wool oil or leach cotton wool oil;
(2) filter;
(3) alkali-refining deacidification;
(4) under vacuum condition, carry out carrying out precipitation after high temperature dehydration;
(5) be refined into Oleum Gossypii semen.
As preferably, described dehydration is that cottonseed moisture is down to below 0.02%.
As preferably, described precipitation is that the quantity of solvent of Oleum Gossypii semen is 50 * 10
-6below.
Beneficial effect: Oleum Gossypii semen method for refining simple process of the present invention, adopt effectively precipitation of the method, make the color and luster of grease in lower level, quality and the use properties of grease have been improved, greatly reduce production cost, reduce Oleum Gossypii semen refining refining consumption rate, be suitable for large-scale industrial production.
