Embodiment 2

[0033] The present embodiment adopts the device of embodiment 1 to extract castor oil, specifically comprises the following steps:

[0034] (1) Grinding and soaking: Put the castor kernels that have been shelled and peeled off the seed coat into the pulverizer 1 for pulverization (dry pulverization), and then send them into the soaking tank 2. Add phosphate buffer solution at a ratio of 1:4g / ml, turn on the agitator and jacket heating or cooling device inside the soaking tank 2, maintain the temperature in the tank at 30°C, soak for 4 hours, and send the soaked material to the intermediate storage tank I3;

[0035] (2) Enzyme reaction: use the feed pump I4 to send the material soaked in step (1) from the intermediate storage tank I3 to the enzyme reactor 5, adjust the pH value of the soaked slurry to 6.5 with hydrochloric acid solution, and add equivalent The raw material is neutral protease with 3% mass of castor kernels, the stirrer and heating or cooling device...

Embodiment 3

[0039] The present embodiment adopts the device of embodiment 1 to extract castor oil, specifically comprises the following steps:

[0040] (1) Grinding and soaking: Add the castor kernels of shelled and peeled seed coats into pulverizer 1 for pulverization (dry pulverization), and then send them into the soaking tank 2, according to the mass-volume ratio of castor kernels and phosphate buffer solution. Add phosphate buffer at a ratio of 1:3g / ml, turn on the agitator and jacket heating or cooling device inside the soaking tank 2, maintain the temperature in the tank at 35°C, soak for 2 hours, and send the soaked material to intermediate storage tank Ⅰ3 ;

Abstract

The invention relates to a method for extracting ricinus communis oil by using an aqueous enzymatic method. The method comprises the following steps of: (1) crushing and soaking; (2) carrying out enzyme reaction; and (3) carrying out filtration and centrifugal separation. The invention also relates to a device for extracting the ricinus communis oil by using the aqueous enzymatic method. The method and the device have the advantages that the process is simple and convenient, the equipment is simple, operating conditions are mild, the extracting temperature is low, organic solvents are not required for being utilized to assist extraction, fat and protein resources in ricinus communis seeds can be comprehensively utilized, and the oil yield and fat quality of the ricinus communis seeds are improved.

Description

technical field [0001] The invention relates to a method and a device for extracting castor oil, in particular to a method and a device for extracting castor oil by an aqueous enzymatic method. Background technique [0002] castor ( Ricinus communis L.) is a dicotyledonous annual or perennial herb of the genus Castor in the Euphorbiaceae family, one of the top ten oil crops in the world, and the main component of its seed oil is 12-hydroxyoctadecenoic acid glyceride, accounting for about 90%. Oil with high hydroxyl value has unique properties and features that other oils cannot match: high viscosity, low freezing point, resistance to severe cold and high temperature, widely used in chemical industry, light industry, metallurgy, electromechanical, textile, printing and other industries and medicine It is also a valuable industrial oil among vegetable oils. In view of the above characteristics, castor oil is regarded by relevant experts as a renewable "green oil" resource th...
