This method has a lot of benefits for you and you may never know.
The steps of oil plant pretreatment, rinsing, stripping and crushing, soaking, and pumping water through a centrifuge to separate plant oil, crude protein, and plant fiber products make up a technique of water leaching to extract plant oil, plant crude protein, and plant fiber.
To maintain a safe and wholesome diet for the general public, the process is primarily offered for soybean, peanut, sesame, oil tea camellia, perilla Fructus, sea buckthorn, and safflowers.
It improves oil yield and quality, more effectively separates oil from protein, and guards against contamination from chemical solvents.
The present invention relates to an extraction method and a water leaching method for extracting oil plant products, more particularly to an extraction method for extracting plant fiber, plant oil, and plant crude protein from crops like soybean, peanut, sesame, oil tea camellia, perilla Fructus, sea buckthorn, and safflowers.
Description of the prior art in depth
For a very long time, China's industry for processing agricultural products has lagged well behind that of other nations.
The level of the food processing industry has increased after the reform because the department of food provisions has implemented technology and equipment for processing food provisions from developed nations.
However, the food processing sector as a whole is having trouble because of its small firm size, dispersed processing facilities, and primary processing-only policy for the bulk of its plants.
In addition to preventing the justification and full development of agricultural goods' resources, the underdeveloped state also causes a comparative decline in the quantity and quality of crops, lowering their competitiveness in the market.
With the biggest soy and peanut production in the world, China has a wealth of oil plant resources.
This presents a convincing case for making the most of such a special advantage by emphasizing agriculture driven by technology to further unlock the potential of edible oil and refine it to increase the competitiveness of local edible oil products.
By way of illustration, soy provides a significant source of both high-quality oil and protein.
Soybean oil may be extracted using current technologies without affecting the protein content of the bean.
In other words, the main goal is to increase oil yield while utilizing soybean protein to the fullest.
Peanut oil and other oil plants can be gathered using modern technology to maximize the exploitation of their essential ingredients, much like the soybean, which can be entirely commercialized.
Despite the existence of several oil plant production facilities, the utilization of oil plants, particularly plant proteins, is not as satisfactory as anticipated in China due to weak manufacturing technology.
The pressing method, which involves employing physical pressure to remove the oil directly from the plant without the need for chemical solvents, is preferred by domestic peanut oil extraction facilities.
The pressing process is risk-free, healthy, and contaminant-free, but it results in subpar production, average quality, and denatured protein in peanuts.
Additionally, because the grain cake produced by pressing is better used as fertilizer or animal feed, it is a waste of a protein resource.
The chemical solvent leaching method, which makes use of the fact that a chemical solvent's solubility changes depending on the item to be dissolved, is used by the majority of soybean extraction facilities in the United States.
The constituent parts of a solid object are dissociated from one another using the solvent method, also referred to as "extraction." No.
6 oil extraction solvent, also referred to as #6 light gasoline, is the organic solvent used in the extraction process.
The plant material is completely mixed with the organic solvent before extraction.
While the oil enters the solvent from the cells, the solvent enters the plant's cells through the cell walls.
Oil is practically disseminated from plant cells to separate oil from protein with a constant supply of fresh solvents.
By using this extraction technique, soybean oil is produced with a high oil yield, less labor-intensive process, better working conditions, and greater grain quality.
Compared to pressing, the solvent method increases oil yield and decreases denatured protein, but it has several drawbacks, such as an inherited flaw that results in a higher level of residual solvent that compromises food safety and health, too many workstations and drawn-out processes, excessive energy consumption (it requires five stages of extraction), and higher production costs.
The quality of the oil and the dried grain would be negatively impacted by solvent residues, leading to insurmountable problems regarding the safety of food and human health, environmental pollution, and production security.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a process for extracting plant oil, plant crude protein, and plant fiber utilizing a water-soaking method, which avoids the drawbacks of the standard methodology (such as a lengthy process and solvent contamination).
The following stages are included in the current innovation to accomplish its goal:
(1) Selection of an exceptional oil plant for oil extraction as the raw material preparation;
(2) Rinsing: either manually or mechanically rinsing the raw material;
(3) Stripping and Crushing: The oil plant is stripped and crushed using specialist equipment;
(4) Soaking: Water is submerged over the crushed and stripped oil plant;
(5) Separating: To separate plant oil, plant crude protein, and plant fiber, the soaked oil plant is passed into a centrifuge with water.
The temperature of the raw material is controlled between 30 and 55.5 degrees Celsius, the soaking length is controlled between 2 and 8 hours, and ultrasonic technology is simultaneously used in step (4) of the soaking process.
After being extracted from plants using the soaking method of the present invention, the final products of plant oil, plant crude protein, and plant fiber are then concentrated and dehydrated in Step (6), where osmosis and ultrafiltration are carried out and the produced water is refilled into a soaking vessel for further use.
The process is made simpler, the flow is shortened, and less energy is used, allowing for commercial manufacturing and ensuring product safety.
The present invention enables full raw material exploitation and a complete reclaim of protein, sugar, and fiber using the existing osmosis and ultra-filtration processes to ensure clean production for achieving the ultimate goal of pollution-free effluence.
This helps to achieve sustainable development and improve environmental protection.
DESCRIPTION OF THE PREFERRED EMBODIMENTS IN DETAIL
A process that uses water leaching to extract plant fiber, crude protein, and oil from plants includes the following steps:
(1) Preparing the raw material Since plant oil has been proven to be safe for human health, it is utilized as the raw material for oil extraction in soybean, peanut, or other high-quality oil plants, ensuring diet health.
(2) Rinsing: The selected oil plant is rinsed either manually or mechanically, and the selected soybean or peanut may be rinsed using the current equipment.
(3) Stripping and Crushing: The selected soybean or peanut is stripped and crushed using a specialized machine.
(4) Soaking: After being stripped and crushed, the soybeans or peanuts are completely submerged in water for soaking, and then the oil-producing plant's cell wall is broken down using ultrasonic waves to extract the oil and separate it from the original active protein.
It has been discovered that the required temperature range for the soaking process is between 30 and 55.5 degrees Celsius.
is ideal, and 50 degrees Celsius is the ideal temperature for soaking.
following repeated testing and analysis.
If the soaking temperature is higher than the ideal range or the oil output is decreased, the protein in the soybean or peanut is susceptible to denature.
For controlling the soaking temperature within the range, a temperature control device is available.
The soaking process can take anywhere between two and eight hours.
If the process takes too long, it becomes inefficient, and if it takes too little time, the oil output is insufficient.
Six hours is the ideal amount of time for soaking.
(5) Separating: To separate plant oil, plant crude protein, and plant fiber, soaked soybeans or peanuts are placed into a centrifuge with water.
Plant crude protein and plant fiber are further processed into other byproducts, such as sugar, which is derived from plant crude protein following osmosis and ultrafiltration operations, and cellulose, which is taken from plant fiber.
After refinement, plant oil becomes edible oil.
(6) Water reuse: To conserve water, cut production costs, and safeguard the environment, the water produced from the concentration and dehydration of the separated plant crude protein using osmosis and ultrafiltration technologies is directly refilled into the soaking process.
Oil extraction from soybean, peanut, sesame, oil tea camellia, perilla Fructus, sea buckthorn, and safflower is the main application of the current invention.
Since soybean oil extraction is the most complicated, if it is successful with soybeans, it should be successful with all other oil plants.
The present invention is applied in industrialized production technology under lower temperature conditions to successfully separate plant oil, plant crude oil, and plant fiber out of oil plant while successfully resolving the issues of residual chemical solvent and side products with little value, achieving high yield production, premium quality plant oil.
Additionally, the present invention considers the use of the plant crude protein after the extraction of the plant oil by supplying high-quality and contamination-free plant active protein by separating the plant protein from the oil in water at a lower temperature to maintain high activity (i.e., a high PSI) of the protein, maximizing the utilization of oil plant resources and offering a sound and complete industrial chain for the production of the protein.
