Problems solved by technology

According to a large number of experimental results, the pressing method is used for the jacaranda fruit. The low-temperature cold pressing takes a long time and the oil yield is low. After high-temperature frying, the oil yield is high and the time is saved, but the quality of the oil is damaged.
The extraction rate of the oil produced by the leaching method is the highest, but the oil produced by this method has the problem of a large amount of solvent residue, and the market price is lower than that of the oil produced by other methods, which affects its economic value

specific Embodiment 1

[0019] Accurately weigh 100KG of fresh jatropha fruits that have been picked from Tongjiang County, Bazhong City, Sichuan Province, and crushed after drying and inactivating enzymes. Use the STZ-1 ultrasonic extraction tank for jatropha to crush for 20 minutes. The extractant is petroleum ether, the ultrasonic frequency is 28.1kHz, and the ultrasonic intensity is 20W / cm 2 , the ratio of material to liquid is 1:12 (g / mL), the temperature of the whole process of ultrasonic crushing is controlled at 80 degrees Celsius, and 12.4 kg of jatropha crude oil is obtained after solid-liquid separation and oil-water separation in a centrifuge.

specific Embodiment 2

[0021] Accurately weigh 100KG of fresh jatropha fruits that have been picked from Tongjiang County, Bazhong City, Sichuan Province, and crush them after drying and inactivating enzymes. Use the STZ-1 ultrasonic extraction tank for jatropha to crush for 30 minutes. The extractant uses petroleum ether, the ultrasonic frequency is 31.1kHz, and the ultrasonic intensity is 20W / cm 2 , the ratio of material to liquid is 1:15 (g / mL), the temperature of the whole process of ultrasonic crushing is controlled at 70 degrees Celsius, and 14.8 kg of jatropha crude oil is obtained after solid-liquid separation and oil-water separation in a centrifuge.

specific Embodiment 3

[0023] Accurately weigh 100KG of fresh jatropha fruits that have been picked from Tongjiang County, Bazhong City, Sichuan Province, and crush them after drying and inactivating enzymes. Use STZ-1 jatropha ultrasonic extraction tank for crushing for 35 minutes. The extractant uses petroleum ether, the ultrasonic frequency is 22.7kHz, and the ultrasonic intensity is 20W / cm 2 , the ratio of material to liquid is 1:10 (g / mL), the temperature of the whole process of ultrasonic crushing is controlled at 50 degrees Celsius, and 14.3 kg of jatropha crude oil is obtained after solid-liquid separation and oil-water separation in a centrifuge.

[0024] The invention can quickly extract the oil from the jatropha at a low temperature below 60 degrees Celsius, save the oil production time, and at the same time increase the oil yield of the jatropha per unit time without any damage to the quality of the oil and less solvent residue. This is because, when the temperature is too high, the extr...

Abstract

The invention belongs to the field of oil extraction technology and ultrasonic transduction technology, and specifically relates to a rapid extraction method of idesia oil. The rapid extraction method comprises following core steps: branch removing of idesia; impurity removing of idesia; washing of idesia fruits; fruit drying (enzyme deactivation), and fruit smashing. The rapid extraction method is characterized in comprising following steps: ultrasonic smashing, solid-liquid separation, and oil-water separation, wherein an ultrasonic transducer is used for cell wall smashing of smashed idesia fruits, and the ultrasonic transducer is obtained by arranging ultrasonic arrays in an extraction pond; a centrifuge is used for solid-liquid separation; and the idesia oil is obtained via oil-water separation. Advantages of the rapid extraction method are that: ultrasonic wave accelerated extraction of idesia oil at a low temperature is realized; extraction efficiency of idesia oil is increased; extraction time of idesia oil is shortened; oil extraction of fresh idesia fruits is realized; oil active ingredients are prevented from destroying as far as possible; and large scale ultrasonic wave extraction of idesia oil can be realized.

Description

technical field [0001] The invention relates to oil extraction technology and ultrasonic energy conversion technology, in particular to a rapid extraction method for jatropha oil. Background technique [0002] The jacaranda tree is a native tree species in my country. Its fruit can contain oil in both the peel and seeds. The oil content of the pulp is 40%-45%, and the oil content of the seeds is 22%-25%. The linoleic acid in tung tree oil is as high as 51%-81%, which has a good ratio of fat and acid, and is a high-quality health-care woody edible oil. In particular, jatropha oil contains DHA, which is rarely seen in other vegetable oils. Since linoleic acid is related to the synthesis of prostaglandins and squalene in the human body, and DHA is an important substance that constitutes the plasma membrane of the brain, jacaranda oil has High nutritional value and health care. The iodine value of kale seed oil is 145.32g I 2 / 100g oil is a dry oil, indicating that the fatty ...
