Linseed oil machine
Flaxseed has been cultivated for more than 5,000 years in human history. It grows all over the world, but the top grade is produced in severe cold regions. Among them, the nutritional value of flaxseed in Northwest Canada is the highest in the world.
The sum of crude protein, fat and total sugar content in flaxseed is as high as 84.07%. Flaxseed protein has a complete range of amino acids, and the content of essential amino acids is as high as 5.16%. It is a plant protein with high nutritional value. The content of linseed oil is 53% of α-linolenic acid. α-linolenic acid is an essential amino acid for the human body. It can be converted into eicosapentaenoic acid and docosahexaenoic acid in the human body. They are effective active substances in fish oil. Element.
α-linolenic acid has anti-tumor, anti-thrombosis, lowering blood fat, nourishing brain cells, regulating autonomic nerves, etc., and has received more attention. Flaxseed contains a lot of polysaccharides, which have anti-tumor, anti-virus, anti-thrombosis, and blood-lipid-lowering effects.
The production process of linseed oil machine to produce linseed oil is generally divided into pressing method and leaching method.
The squeezing method is also called "physical squeezing method", which is to squeeze out the oil in the oil by external force, and other chemical solvents are not applicable, so as to avoid the residue of organic solvents in the oil.
The pressing production process retains the active ingredients in flaxseed to the greatest extent - polyunsaturated fatty acids, protein, dietary fiber, vitamins, trace elements and other nutrients that are beneficial to the human body, and are more suitable for special supplements for the human body health care. Press method Tourists choose hot pressing method and cold pressing method, among which the linseed oil extracted by cold pressing method has higher nutritional content.
The linseed oil produced by the leaching process is also called leaching oil, which is to extract the oil material with organic solvents (such as gasoline, ethanol, etc.), and the leaching method is to use solvent oil (No. , an oil-making process in which oil is extracted after being soaked in a solvent. The "oil" extracted initially is a mixture of organic solvents and oils, etc. It is not edible and must go through a series of refining processes (chemical treatments such as dewaxing, degumming, dehydration, deodorization, deacidification, and decolorization) before it can be eaten. The extraction process can extract almost all the oil in the oil, and the economic benefit is very high. It is the most popular processing method in the modern oil industry.
Comparison of the advantages and disadvantages of the oil making method of the linseed oil machine;
Harvesting and screening of linseed→linseed→cleaning impurities→hulling→crushing→pressing→pressing linseed crude oil→coarse filtration→fine filtration→low temperature crystallization and growth→low temperature filtration→linseed oil
Advantages: Almost all the nutrients in flaxseed are retained, the taste is refreshing and not greasy, and the content of polyunsaturated fatty acids is rich.
Disadvantages: low oil yield, relatively high production cost
extraction method
Advantages: very high oil yield, low cost and higher economic benefits. The most popular processing method in the modern oil industry.
Disadvantages: The investment in machinery and equipment is relatively large, and the solvent is dangerous during the extraction process.
Introduction of the oil making process and equipment configuration of the linseed oil machine;
A complete linseed oil production line includes four parts: raw material pretreatment, pressing/leaching, refining, and filling. The functions of each part and the required equipment are as follows:
Raw material pretreatment of linseed oil machine Raw material pretreatment is a series of processes such as cleaning, crushing, rolling, steaming and frying of linseed. Its purpose is to destroy the cells of the oil plant, change the shape of the oil plant, control the moisture of the oil plant so that it can better extract the oil, and increase the oil yield of the oil. The pretreatment of raw materials is the general name of a series of processes that clean and remove oil materials and process them into materials with certain structural properties to meet the requirements of different oil-making processes.
Commonly used pretreatment equipment includes: vibrating cleaning screen, shelling machine, rolling mill, steamer, crusher, etc.
Selection of oil press or extraction process for linseed oil machine
The pretreated raw materials are sent to the oil press through the conveying auger for pressing to extract oil. Oil extraction equipment commonly used in oil factories includes oil presses and leaching equipment. The choice of these two types of equipment is determined by factors such as the type of oil, output, and the manufacturer's needs. Dayang Company will configure the appropriate oil press or leaching equipment according to the needs of customers.
No. 6 solvent or n-hexane can be used for the leaching of linseed oil, combined with negative pressure evaporation technology, to reduce the evaporation temperature of the mixed oil, reduce high-temperature oxidation, and retain as much nutrient content of leached linseed oil as possible. The leaching machine fully embodies the advantages of normal temperature leaching and low temperature desolventization. When extracting linseed oil, it does not destroy the active substances and vegetable proteins in linseed oil.
The extraction process of the linseed oil machine is as follows:
First, crush and dry the linseed cake, then transport it to the extraction workshop, pass through the conveyor and the sealing auger and enter the extractor, fully contact with the solvent in the extractor to extract the linseed oil, and obtain the mixed oil, and then filter and evaporate , stripping, and condensation to recover the solvent to obtain leached linseed crude oil. In this process, the mixed oil adopts negative pressure evaporation technology, and the first steaming, second steaming and stripping are all carried out in vacuum, and the temperature of additional issuance is low, which greatly reduces oxidation; The leached solvent gas is recovered through the condenser
Introduction of refining process of linseed oil machine
When choosing refining equipment, determine the quality and grade of oil. According to different working methods, refining equipment can be divided into batch refining equipment, semi-continuous refining equipment and continuous refining equipment. The grades of oils and fats required by customers are different, and the configuration of refining equipment is different, so the price will also be different.
4. Filling equipment
After the refined linseed oil passes the laboratory test, it is transported to the filling workshop for filling and sealing, and then it can be sold in the market after packaging. The equipment required for the filling production line includes filling machines, capping machines, inkjet printers, labeling machines, etc.
According to different factors such as raw material types, oil output, and oil grades of the oil factory, the configuration of the production line will also be different. When purchasing equipment, it is necessary to fully communicate with the equipment manufacturer. After understanding the demand, the manufacturer will design a plan and equipment quotation for reference
