The core technology of the invention is as follows: the core technology of the invention is as follows: under the condition of keeping the complete oil crop particles, the prefabricated grease is expanded to leach out the blank. Under pressure, oil crops are soaked in a solvent, and the temperature is kept at a certain temperature during the soaking process. After soaking for a certain time, the solvent is drained, then the oil crops are puffed under reduced pressure, and the materials are heated in the puffing process. The technological process of swelling the prefabricated grease to leach out the blank can be completed once or repeatedly. During the process of swelling the prefabricated grease leaching blank, the phenomenon of grease leaching also occurs.
Description
One, the technical field
The invention relates to a method for pre-making an oil leaching blank.
Second, background art
The extraction process is a technological process for extracting oil from oil material by using organic solvent. The leaching of oil is referred to as solid-liquid extraction, which is a process of separating the relevant components from solid materials by using the property of different solubilities of different substances in a solvent. In leaching, the oil is treated with a solvent in which the readily soluble components (mainly fats) are dissolved; before oil extraction, oil crops need to be pre-treated by rolling, and in the traditional oil extraction process, the oil crops are rolled into slices by adopting a material crushing and rolling method, such as: the thickness of the soybean embryo piece is 0.3-0.6 mm; the thickness of the peanut sheet is 0.5-1.5 mm; the thickness of the rapeseed embryo piece is 0.3-0.5 mm. The rolling method destroys the shape and the structure of material particles, and rolls the material at high temperature, so that the blank material after further leaching the grease is low in value and can only be used as feed.
Third, summary of the invention
The core technology of the invention is as follows: under the condition of keeping the complete oil crop particles, the prefabricated grease is expanded to leach out the blank.
Firstly, under the pressure state, the oil crops with complete particles are soaked in a solvent, wherein the solvent can be a solvent IV, a solvent VI, liquid carbon dioxide and the like, the pressure is different from the saturated vapor pressure of the solvent to 60MPa, and the temperature is kept at a certain temperature in the soaking process and can be a certain temperature between room temperature and 180 ℃. After the materials are soaked for a certain time, solvent molecules fully permeate into the oil crops, the solvent is drained firstly, then the pressure is reduced to carry out puffing treatment on the oil crops, the materials are heated in the puffing process, and modes such as steam jacket, steam coil indirect heating, hot solvent gas or mixed gas of hot solvent and nitrogen, microwave heating and the like can be adopted, or a plurality of heating modes are combined for use. The technological process of puffing the prefabricated grease to leach out the blank can be completed at one time or repeated for a plurality of times. During the process of swelling the prefabricated grease leaching blank, the phenomenon of grease leaching also occurs.
Through the mode, after the complete particle oil is prefabricated to leach the blank, the blank is put into a leaching device to complete the oil leaching process.
Description of the drawings
Figure 1 is a device for realizing the extraction of embryo material by puffing prefabricated grease.
The equipment comprises a puffing tank, a steam heating jacket, a booster pump, a pressure increasing valve, a pressure reducing valve, a solvent inlet, a solvent outlet and a circulating heating gas inlet
A circulating heating gas outlet, a pressure gauge, a thermometer and the like.
The medium adopted for boosting the pressure in the process is nitrogen.
Fifth, detailed description of the invention
The technological process of the puffed prefabricated oil leaching blank comprises the following steps:
1. placing the oil material into a puffing tank from a feeding hole, and sealing the feeding hole;
2. opening a solvent inlet valve, and adding a solvent into the puffing tank until the solvent can completely soak the oil material;
3. opening a pressure boosting valve, starting a pressure boosting pump to compress nitrogen into a puffing tank, and boosting the pressure of the puffing tank until the pressure is boosted to the pressure required by the process;
4. introducing steam into a steam jacket, heating the puffing tank to a certain temperature, maintaining a certain pressure and temperature for a period of time, and soaking the oil material;
5. opening a solvent outlet valve, and discharging the solvent in the puffing tank;
6. opening a pressure reduction valve, and reducing the pressure of the expansion tank to the pressure required by the process;
7. the heating gas is circulated in the puffing tank through the circulating heating gas inlet and outlet, and the oil crops are heated to finish the puffing process;
8. and opening the discharge port, and discharging the prepared puffed grease leaching blank in the puffing tank.
