AI Technical Summary

Problems solved by technology

The main reason is that the nucleolus is too small, accounting for only about 16% of the fruit, and is wrapped in a hard core shell, which is difficult to separate and utilize

Embodiment Construction

[0011] Non-limiting examples are described as follows:

[0012] 1, with 6 # mineral spirits as solvent

[0013] (1) Crushing - Take 100kg of seedlings and crush them into 3 to 4 pieces on a jaw crusher.

[0014] (2) Separation-carry out rolling separation in the large-diameter rolling sieve (Φ1000), make most of the nucleolus shake out from the shell and pick out the clean shells that do not wrap the nucleolin, and the shell rate of the mixture is 50wt%.

[0015] (3) Leaching - the mixed material is sent to the drying room to be heated to 50-55 °C, immediately put into the leaching tank equipped with a reflux condenser, cover the feeding port, and add 6 # Soak in 80L of solvent (the material just submerged) for 40-50 minutes, separate the extract, and then add 6 # Soak in solvent oil for the second time, soak for 30 to 40 minutes to separate the second batch of extracts, and then add fresh 6 # Solvent oil is subjected to leaching and separation for the third time to obtain...

Abstract

The invention relates to a method for extracting a vegetable oil from kernels of Chinese soapberry fruit, which uses the kernels of Chinese soapberry fruit as the raw materials and comprises the steps of crashing, separation, extraction and post-processing. The method is characterized in that: the extraction step is to carry out extraction on a kernel mixture with 30 to 50 weight percent of rate of hull in kernel by using a solvent at a temperature of between 50 and 60 DEG C; and the solvent is the diesel oil or the 6# solvent oil. In the vegetable oil, the sulphur content is between 5 and 10ppm. And the vegetable oil is very suitable for processing the biodiesel.

Description

1. Technical field [0001] The invention relates to a method for extracting vegetable oil, in particular to a method for extracting vegetable oil from sapindus seedlings. 2. Background technology [0002] Sapindus is a Sapindaceae plant, which is mainly produced in Southeast Asian countries, the Yangtze River Basin of my country and southern provinces. The fruit is crushed and soaked in water, and after shaking, soap-like foam is produced. It is picked by folks and used as soap. [0003] The outer pseudo-skin of Sapindus fruit is rich in natural active substances such as pentacyclic triterpenes, terpenes, sterols and saponins, and has been widely developed and used in chemical, daily-use and pharmaceutical fields. As an environmentally friendly renewable resource, it has attracted people's attention. In recent years, in Panzhihua, Sichuan (100,000 mu), Taizhou, Fujian, Zhejiang, Jiangxi, Tongbai, Henan, Hubei, Yunnan and other places have successively built large-scale plant...
