Problems solved by technology

However, it is difficult to use the seed of the date, because the fat mainly exists in the seed of the date, which is wrapped by a hard lignified shell, so it is often thrown away as waste or burned
CN 102071094 A has proposed to use ultrasonic waves to extract the oil of the date, but this method has the following problems in extracting the oil of the date: 1. The shell and the seeds are crushed together to extract the oil, and the efficiency is low
2. With the solvent extraction method, the amount of solvent used is large, the solvent is wasted, and the recovery of the solvent consumes a lot of energy
3. Simple ultrasonic solvent extraction, low oil extraction rate
4. The use of oil is not proposed, and no further treatment of oil is carried out

Embodiment 1

[0034] (1) Cleaning: Cleaning the core of Rhododendron, washing away the pulp and mud remaining on it, and drying to remove water. Random sampling was used to analyze the proportion of the woody shells of Elaeagnus sativa.

[0035] (2) Pulverization and separation: get 1kg of dried Rhizoma sylvestris and put it into a pulverizer to pulverize, and sieve to remove the large particles that are not pulverized. Weigh the uncrushed large particles.

[0036] (3) Ultrasonic-assisted Soxhlet extraction: Take part of the pulverized Jujube seed and n-hexane at a mass-volume ratio of 1:4, ultrasonicate for 15 minutes in a 100W ultrasonic frequency of 40KHz, then pour it into a filter bag, and pour the solvent into the bottom bottle , put the filter bag into the Soxhlet extractor, maintain a cycle of 6 minutes, and extract for 8 hours. After all the extracts of Elaeagnus sativa powder are completed, proceed to the next step.

Abstract

The invention relates to a method for preparing grease raw materials for biodiesel from elaeagnus angustifolia pit. The method includes 1 cleaning, 2 smashing and separating, 3 ultrasonic-assisted Soxhlet extraction, 4 impurity removing and grease separating, 5 grease degumming, 6 grease deacidifying and 7 grease purifying. The method has the advantages that the extraction efficiency can be improved by the aid of smashing and separating and ultrasonic-assisted extraction processes, the grease raw materials can be applied to preparing the biodiesel and can be reasonably utilized as compared with existing discarded elaeagnus angustifolia pit, the method is beneficial to applying natural renewable resources on a large scale, and the problems in the aspect of the requirements of the mankind onenergy sources can be solved by the aid of the method; experiment procedures are simple, biomass resources can be sufficiently effectively utilized, the method has low requirements on equipment, andthe grease raw materials can be industrially produced by the aid of the method.

Description

technical field [0001] The invention relates to a method for preparing raw material of biodiesel oil by using the seed of Rhizoma saponica, in particular to a raw material of synthetic biodiesel using agricultural and forestry waste seed of Rhododendron as renewable energy, which belongs to the extraction and processing of raw material of biodiesel oil Purification technology field. technical background [0002] As small trees and deciduous shrubs, Elaeagnus maxima grows mostly in Northeast my country, North China, Northwest China and other regions. It has extremely tenacious vitality, strong reproductive ability, and strong ability to resist wind and sand. Therefore, it is also widely planted in Inner Mongolia, Xinjiang, Ningxia, Gansu and other arid desert areas have the reputation of "treasure tree". In recent years, studies have found that not only the fruit of Eleuthero jujube contains a variety of unsaturated fatty acids that are beneficial to the human body. Among th...
