Embodiment 1

[0070] 1) select debittered almonds as raw materials, and perform physical pressing to obtain crude oil and oil cake;

[0071] When the debittered almonds are used as raw materials, the debittered almonds can be prepared by the following method: soak in an aqueous solution at 90°C for 5 minutes, perform peeling treatment, and debitterize the almonds by alternately soaking in warm water at 30°C every four hours. Four times, dehydration, drying at 60°C for 8 hours, cooling, color sorting, and packaging to obtain debitter almonds. The color of the prepared debittered almonds is milky white or off-white, slightly glossy, free from mildew, free from insects, uniform particle shape, no obvious abnormal particles, with the proper aroma and taste of almonds, no peculiar smell, no visible to the naked eye Foreign impurities whose moisture content is less than 10%.

[0072] Water should meet the requirements of GB-5749.

[0073] When pressing, use physical pressing method to avoid sol...

Embodiment 2

[0096] 1) Select sweet almonds as raw materials and perform physical pressing to obtain crude oil and oil cakes;

[0097] Sweet almonds: should comply with the provisions of GB / T 20452. It is required that the sweet almonds have normal color, no mildew, no insects, uniform particle shape, no obvious abnormal particles, have the proper aroma and taste of sweet almonds, no peculiar smell, no visible foreign impurities, moisture less than 10%, raw materials are Selected sweet almonds.

[0098] Water should meet the requirements of GB-5749.

[0099] When pressing, use physical pressing method to avoid solvent residue and high soap content. The specific operation is:

[0100] Put 5kg of raw material into the press bag, put it into the steel drum of the hydraulic press, seal the steel drum, and prepare for pressing. When the pressure reaches about 10MPa, the oil discharge starts. When the pressure reaches 55Mpa, the oil discharge basically ends. The oil is basically over. Durin...

Embodiment 3

[0122] 1) select debittered almonds as raw materials, and perform physical pressing to obtain crude oil and oil cake;

[0123] When debittering almonds are used as raw materials, the debittering almonds can be prepared by the following method: soak in an aqueous solution at 92°C for 8 minutes, perform peeling treatment, and debitterize by alternately soaking in warm water at 40°C every four hours with hot and cold water, alternately Four times, dehydration, drying at 65°C for 9 hours, cooling, color sorting, and packaging to obtain debitter almonds. The color of the prepared debittered almonds is milky white or off-white, slightly glossy, free from mildew, free from insects, uniform particle shape, no obvious abnormal particles, with the proper aroma and taste of almonds, no peculiar smell, no visible to the naked eye Foreign impurities whose moisture content is less than 10%.

[0124] Water should meet the requirements of GB-5749.

[0125] When pressing, use physical pressi...

Abstract

The invention relates to a processing technology of apricot kernel oil. The processing technology comprises the following steps: 1) debitterized dry apricot kernels or sweet apricot kernels are selected as raw materials and subjected to physical squeezing, and crude oil and oil cakes are obtained; 2) the crude oil is filtered, and a filtrate is collected; 3) water washing and stirring are performed: the filtrate is preheated, steam in sprayed into the filtrate, the mixture is stirred, and the oil temperature is increased; salt is added to the oil when the temperature is 85-90 DEG C, the mixture is evenly mixed and left to stand, three layers are obtained, cleaned oil on the middle layer is collected, and the temperature is reduced when reaching 125-145 DEG C; 4) degumming is performed: the cooled cleaned oil is heated to 90-110 DEG C, brine is added, the mixture is stirred and left to stand, floating oil on the upper layer is skimmed off, water at the bottom is discharged, and the degummed cleaned oil is obtained; 5) the degummed cleaned oil is subjected to vacuum drying, cooling is performed, and grease is obtained; 6) the grease is filtered and packaged, and a finished product is prepared. The processing technology has the advantages that an oxidant is not needed to be added, the cyanide content is low or even no cyanide is contained, the oil yield is high, the operation is simple, the cost is low and the like.

Description

technical field [0001] The invention relates to an oil processing technology, in particular to an almond oil processing technology. Background technique [0002] Almond oil is a kind of oil extracted from almonds. It is light yellow and transparent, and has a delicate taste. It is not only an excellent edible oil, but also has edible and medical value. It can be used as lubricating oil, paint, cosmetics and high-quality soap important raw materials. [0003] Most of the existing almond oil processing technology adopts the method of solution extraction. Commonly used solvents include organic solutions such as anhydrous ether, petroleum ether, n-hexane, and methylene chloride. Although the oil yield is high, solvent residues are prone to occur. Phenomenon, if improper operation can easily affect the quality of extracted almond oil. [0004] A few of them adopt the method of pressing, but due to the unreasonable setting of operating conditions and operating steps, there are p...
