Method for producing low-temperature peanut oil

Abstract

The production method of low temp. peanut oil includes the procedures of breaking, extracting crude oil and refinement, in concrete, said method adopts the following steps: adding broken peanut vernel into peanut oil, grinding to make pulp; grinding to 60-180 meshes and press-filtering at 30-70 deg.C to obtain oil pump, and making the oil content of peanut cake be reduced to 2-4% of obtain peanutcrude oil ,heating the crude oil to 50-80 deg.C and adding water whose adding quantity is 10-30% of oil weight, stirring, precipitating, taking supernatant oil, heating to 60-80 deg.C, dehydrating under the condition of the vacuum for 10-30 min. and filtering at 0.1-0.3 MPa so as to obtain the low-temp. peanut oil.

Description

technical field

[0001] The invention relates to a method for processing edible oil from peanuts with high oil content, and belongs to the technical field of edible vegetable oil processing methods. Background technique

[0002] The production process of vegetable oil is to use oil seeds such as peanuts and soybeans as raw materials, degrease to obtain crude oil, and then refine the crude oil to obtain finished oil. At present, the high-temperature method is generally used in the production of peanut oil at home and abroad, and some low-temperature leaching methods are also used.

[0003] The high-temperature method of oil production is to heat the raw materials to 120-140 ° C and steam fry for 40-60 minutes. One method is to squeeze the oil out of the oil from the steamed and fried materials with a screw press. The temperature of the raw materials during extrusion is as high as 200 -240°C; Another method is to extrude the steamed and fried material by hydraulic method. Alth...
