Embodiment 1

[0013] Example 1, select castor beans by classification, firstly clean them, no impurities and no pests, then pre-press a part of castor oil after shelling, and then use methanol to leach castor oil under ultrasonic strengthening conditions, the leaching temperature is 20°C , the ratio of the mass of the pre-pressed cake to the volume of methanol is 1:3, the leaching time is 60min, the ultrasonic unit volume power is 8W / L, and the ultrasonic frequency is 20kHz. The obtained mixed oil is desolvated, the solvent is recovered and recycled, the castor oil is rectified, and the castor wet meal is detoxified at high temperature and used as feed.

Embodiment 2

[0014] The difference between Example 2 and Example 1 is that the leaching temperature is 50°C, the ratio of pre-pressed cake mass to methanol volume is 1:4, the leaching time is 40min, the ultrasonic unit volume power is 20W / L, and the ultrasonic frequency is 45kHz.

Embodiment 3

[0015] The difference between Example 3 and Example 1 is that the leaching temperature is 70°C, the ratio of pre-pressed cake mass to methanol volume is 1:5, the leaching time is 40min, the ultrasonic unit volume power is 30W / L, and the ultrasonic frequency is 100kHz.

Abstract

The invention discloses a methanol leaching castor oil process method. Regulating castor seed choose is done after the cleaning of the castor seeds free from impurity as well as insect damage. The seeds are of shell removal, crush or pre-pressure to make part of castor oil. The castor oil is leached with the ultrasonic or physical field aided condition method. Under the ultrasonic condition, the castor oil is leached by the methanol leaching solute, which improves the existing solute leaching method, greatly shortens the leaching time, decreases the raw material consumption and lowers the experiment cost, thus being the new oil leaching method of the lower cost, short leaching time and high oil production rate. The invention solves the problems that current bio-diesel preparation method has high requirements to the oil, long technique procedure, large consumption of various raw materials, reagents and equipments, serious reagent pollution and high production cost.

Description

Technical field [0001] The invention belongs to the technical fields of oil industry, chemical industry and the like, and in particular relates to a processing method of solvent leaching castor oil. Background technique [0002] Castor (Ricinus communis) is a 1-year or perennial herbaceous plant of Euphoribia L., which is resistant to barrenness, strong adaptability, convenient cultivation and management, relatively extensive cultivation, high comprehensive utilization value, and long industrial chain. Regardless of the region and climate, it is resistant to certain salinity and alkali, has few pests and diseases, has strong stress resistance, and has a well-developed root system, which is conducive to water and soil conservation. Castor bean has a high oil content, and the castor oil contained in it is the only natural fatty acid containing hydroxyl groups. It has special physical and chemical properties and is widely used. Because planting castor has a wide range of uses ...
