Problems solved by technology

In this method, the pressed oil is obtained by pressing first, and then the sodium bentonite, crystal alkali, and xanthan gum compound are added to the pressed oil for physical adsorption refining. , Filtration and separation are often time-consuming and labor-intensive, and combined filtration equipment is required for fine filtration, and the oil loss in the refining process is also relatively large
[0005] Moreover, from the perspective of the above-mentioned vegetable oil production method, the pressing and refining processes are carried out step by step, and there are problems such as long procedures, many equipments, and long time consumption, and it is easy to cause loss of active ingredients in oils and fats.

Abstract

The invention discloses a method for preparing oil by synchronously squeezing oil materials and refining solid phases, which comprises the following steps: (1) oil material pretreatment: pretreating oilseeds by adopting a heat treatment method, and finishing the pretreatment when the temperature of the oilseeds is stabilized at 120-160 DEG C; (2) oilseed tempering and refining agent premixing: premixing the oilseeds pretreated in the step (1) with a solid-phase refining agent to obtain a premix, wherein the solid-phase refining agent accounts for 0.5 wt%-2wt% of the mass of the oilseeds, and the water content of the oilseeds is 2 wt%-5wt%; and (3) synchronous squeezing and solid-phase refining: squeezing the premix obtained in the step (2), and filtering to obtain squeezed oil and cake meal. Physical squeezing and refining of the oilseeds are synchronously completed, traditional tedious oil processing steps of squeezing firstly, then degumming step by step, deacidifying and the like are omitted, and the method has the advantages of being short in oil making procedure, high in oil yield, good in oil quality, low in energy consumption and refining consumption, environmentally friendly and the like.

Description

technical field [0001] The invention belongs to the technical field of oil processing and specifically relates to a method for synchronous pressing and physical refining of oil. Background technique [0002] The existing oil processing technology is "high-temperature steaming-five de-refining". The existing vegetable oil production technology mainly adopts the technology of flaking-steaming-pre-pressing and leaching. The main steps include steaming and frying at a high temperature of 110-130°C , Consumption of a large amount of electricity and steam, deep color of crude oil, high acid value and phospholipid content, serious oil oxidation and other problems, the follow-up must go through multi-step refining such as degumming, deacidification, decolorization, and deodorization to make the product meet the relevant national standards. A large number of chemical reagents will be used in the lengthy refining process, which will also lead to the loss and damage of natural active s...
