Yes, but the yield is a little bit higher and the quality is higher.

Wild rape can be squeezed for oil and has a good taste.

Wild rapeseed can be extracted for oil and is an ecological edible oil.

Hello, dear.

Wild rape is the grass in our northern wheat field, called Artemisia annua, it is a kind of Chinese medicinal material, belongs to the cruciferous family, an annual herbaceous plant, the seeds can be squeezed for oil and edible, the seed content is 40%, and it has the effect of "expectorant and asthmatic, cardiac diuretic". So the oil is not only edible, but also has medicinal value.

It can be eaten, and the oil yield is particularly low.

Wild rapeseed has the effect of promoting blood circulation, clearing the liver and relieving gallbladder.

1.Promote blood circulation: Rapeseed has the effect of promoting blood circulation and improving the problem of poor blood circulation.

2.Liver clearing and gallbladder relieving: wild rapeseed has the effect of clearing the liver and gallbladder and can play a certain protective role in the liver.

Suitable for. Those who have poor blood circulation and stay up late.

Contraindicated. Patients with high blood pressure.

It is not advisable to eat together. Grape.

Wild canola cannot be eaten with grapes, as it may cause discomfort such as abdominal pain.

How to eat. Serve after oil extraction].

After the wild rapeseed is processed in the oil extraction machine, the oil can be used for stir-frying, mixing vegetables, etc.

According to the function, the oil press can be divided into screw oil press and hydraulic oil press.

1. Hydraulic oil press.

The hydraulic oil press is a traditional small oil press, and the production process is intermittent. The process is characterized by low operation technical requirements, high oil yield, and high crude oil, but the labor intensity is large. The applicable occasions of the hydraulic oil press are:

The processing capacity is small, the production is small, and the daily processing capacity of a single unit is about 1 ton.

2. Screw oil press.

The fully automatic screw press is an oil press that can operate continuously. The technical characteristics are: low operation technical requirements, high oil yield, poor crude oil quality compared with hydraulic oil press, and labor intensity lower than that of hydraulic oil press.

The automatic screw press is suitable for small processing capacity, small workshop production, and the daily processing capacity of a single machine is about 2-8 tons.

3.Large and medium-sized screw oil press units.

The screw oil press unit is suitable for large and medium-sized, continuous and large-capacity oil plants. The technical characteristics are: continuous production, low labor intensity, and high oil yield.

1. Production process of rapeseed oil extraction equipment:

1.Cold pressing process: rapeseed.

Clean and remove impurities, cold-pressed, cold-pressed crude oil, coarse filtration, refining, cold-pressed oil, rapeseed cake.

2.Hot pressing process: rapeseed, cleaning and impurities, steaming and frying, pressing out the oil, and precipitating.

refining camellia oil; The main equipment components: hoist.

Clean the sieve, steam the wok, the oil press, the filter, the crude oil temporary storage box, 2. Rapeseed oil.

Crude oil refining equipment production process.

Crude oil one alkali refining one degumming one decolorization one deodorization one dewaxing workshop (or refined oil workshop).

The main equipment consists of: refining tank, decolorization tank, deodorization tank, heat conduction oil furnace, filter, etc.

Third, rapeseed oil dewaxing equipment process.

In the processing of oils and fats, the inherent wax in the oils can be separated from the oils through the winterization dewaxing process, which can improve the nutritional value of the oils and fats and improve the taste and quality of the oils.

The main equipment consists of: freezer, filter, crystallization tank, refined oil tank, etc.

The cost of equipment is related to the capacity, configuration, and quality of refined oil requirements, which cannot be said in a word;

1. Peanut oil.

Peanut oil is light yellow and transparent, the color is clear, the smell is fragrant, the taste is delicious, and it is a relatively easy to digest edible oil. Peanut oil contains more than 80% unsaturated fatty acids, and also contains saturated fatty acids such as palmitic acid, stearic acid and eicosanic acid. In addition, the fatty acid composition of peanut oil is relatively reasonable and easy to be digested and absorbed by the human body.

2. Rapeseed oil.

Since the raw material for oil extraction is the seed fruit of plants, it generally contains a certain amount of seed phospholipids, which are very important for the development of blood vessels, nerves, and brains. Canola oil has little or no cholesterol and is safe for most people to consume.

Rapeseed oil is an oil with a particularly high content of erucic acid, whether it will cause myocardial fat deposition and damage to the heart is still controversial, and patients with coronary heart disease and hypertension should still pay attention to eating less.

3. Corn oil.

Corn oil is an oil extracted from corn germ and is rich in vitamin E, a natural antioxidant. Corn oil is golden and transparent in color, fragrant and fragrant, which is very suitable for quick cooking oil, which can not only maintain the color and aroma of vegetable dishes, but also do not lose nutritional value.

4. Sunflower oil.

Sunflower oil is a healthy edible oil known for its high content of linoleic acid, and the content of natural vitamin E is the highest among all major vegetable oils; Linoleic acid is an essential fatty acid for the human body, and its content can reach about 70%. Sunflower oil is rich in carotene, which is more than peanut oil, sesame oil and soybean oil. It also contains nutrients such as glucose and sucrose, and its calorific value is also higher than that of soybean oil, peanut oil, sesame oil, corn oil, etc., which is easy to be absorbed by the human body, and the absorption rate can reach more than 98%.

In addition, sunflower oil is light and transparent, can retain the natural food flavor when cooking, and after a little heating, it has a strong fragrance, and it is the best tasting edible oil except for sesame oil. It also has a high smoke point, which can avoid the harm of oil smoke to the human body. Because sunflower oil is rich in nutrients and has a variety of health care functions for the human body, it is reputed"High-grade nutritional oils"。

In fact, the way to extract rapeseed oil is physical oil extraction. This method should sound higher and more environmentally friendly.

Nutritionally speaking, cold-pressed oil is better than hot-pressed oil, and when hot-pressed, rapeseed undergoes high temperature in the wok, which damages the free ions in the rapeseed, and smells fragrant, but it does not taste as cold-pressed oil.

First, the preheating temperature of the oil press is raised to about 110-140 degrees, and then the screened rapeseed is poured into the drum wok, stir-fried over low heat until dark yellow, and the rapeseed is cooled to about 60 degrees, and then poured into the oil press for pressing. <>

It is good to use the traditional pressing method.

In real life, solvent leaching is also used after pressing.

This thing can't be eaten directly.

Unhealthy. Many people think that this kind of "unprocessed by modern industrial means" and "no additives" of earth-pressed oil is more natural, nutritious and healthy, in fact, it is completely contrary to modern food science, and it does not meet the national standards for safety.

In the process of making clay oil, it is generally treated at high temperatures, which will form some benzopyrene, which is a possible carcinogen.

Because the clay oil has not been refined, it may also contain many unknown risks such as heavy metals and pesticide residues.

Rapeseed oil is not as sticky and resistant to high temperature as soybean oil, and the impact of rapeseed oil on blood lipids is smaller than that of soybean oil.

How do farmers squeeze rapeseed out of their oil? Maybe you've eaten canola oil, but you've not necessarily seen rapeseed oil pressed. In rural areas, farmers are accustomed to planting rapeseed and then using rapeseed to squeeze oil, squeezing out the oil is fragrant and pure, and the fragrance of rapeseed oil can be smelled ten miles away.

So, how does the rapeseed grown by farmers turn from seeds to rapeseed oil? Next, I will take you to the rural oil mill to see the whole process of rapeseed oil extraction.

First, first of all, the rapeseed is dried and cleaned, so that the oil squeezed out will be very clean and free of impurities. When squeezing the oil, the wok is first fired at 70 degrees, and the rapeseed in the pool is rolled into the wok by the screw.

Second, the general sun-dried rapeseed only needs to be stir-fried for 20 minutes, when the temperature gauge points to 150 degrees of high temperature, then the rapeseed has been fried, the staff must open the wok-gate gate as soon as possible, and put the rapeseed into the second pool.

Third, Jiaolong will suck the fried rapeseed into the iron bucket of the oil press and start to extract oil.

Fourth, open the iron bucket gate to flow rape into the press shaft, so that the vegetable oil flows into the iron plate from the press shaft, and then flows into the barrel containing oil through the iron trough.

5. Pour the rapeseed oil into a filter and filter, it takes five minutes to filter each barrel of rapeseed oil.

6. Pour the filtered rapeseed oil into an aluminum barrel to boil the rapeseed oil and remove phosphorus.

7. Pour the dephosphorized rapeseed oil into the cooler to cool, and it only takes seven or eight minutes to drop from a high temperature of more than 150 degrees to about 50 degrees, and then put the cooled rapeseed oil into an iron drum.

8. Finally, pour the cooled rapeseed oil into the prepared plastic bucket.

According to the cold and hot pressing process, the oil extraction process of rapeseed is slightly different.

Rapeseed cold pressing oil extraction process, rapeseed through stone screening to obtain clean rapeseed, and then rapeseed cold pressed oil press for oil extraction, the squeezed rapeseed oil in filtration, if the oil requirements are high, such as the need to meet the national standard of one or two rapeseed standards, then also need to go through refining equipment.

Rapeseed hot pressing oil extraction process, the pressing process and cold pressing are basically the same, the only difference is that there is an additional process between cleaning and pressing, frying, that is, using a wok to heat rapeseed.

Rapeseed oil extraction process.

First, hot pressing; Rapeseed cleaning, softening, rolling, steaming, frying, pressing, crude oil, refining, refined oil.

2 Pre-pressing – leaching process.

Rapeseed cleaning, softening, rolling, steaming, frying, pre-pressing, leaching.

3.Direct leaching.

Rapeseed rolling, granulation, leaching.

No one will go straight to eating oil, and canola oil can also be used as cooking oil for cold vegetables.

No! The erucic acid content of rapeseed oil is as high as 40%, and the national food safety standard stipulates that it should not be higher than 3%, so it is recommended to buy rapeseed oil that meets the national production standards, such as Arowana grandmother Township small pressed rapeseed oil, carp rapeseed oil, etc.

Rapeseed oil is edible, and this oil is very tasty.
