Problems with soybean oil produced by soybean oil presses

Soybean oil? No problem, the oil that comes out is basically eaten directly, and there is no need to use other equipment to process it, unless you want to sell refined oil in bulk, then you have to purchase packaging equipment. If you have enough oil presses, you can go to Guangzhou Guoyan to see, their oil presses are good, and there are subsidies for agricultural machinery to go to the countryside.

Yes, but not if it is oil from the leaching method.

Diyiwei live oil press adopts the principle of soft pressure to ensure the oil yield and at the same time, peanuts and soybeans can be restored to their original state after oil extraction. After the oil is pressed, the soybeans can be processed into tofu and other soybean products, and the peanuts can be made into drunkard peanuts and fish skin peanuts after the oil is pressed. It avoids the huge waste that the old-fashioned oil press can only make feed after squeezing the oil.

For more information: "Emperor Yiwei Living Oil Press".

Welcome everyone who is interested in oil extraction with peanuts and soybeans to try squeezing and operate it yourself.

After squeezing out, it is filtered.

Soybean oil can be pressed by the screw press, and now the new screw press has vacuum oil filtration, and there is no need for the old-fashioned barrel oil filtration!

The moisture of the material is inappropriate, and the optimal moisture is not reached, which is not conducive to oil production. Too dry and too wet will affect its oil yield.

2.The temperature is inappropriate and too low, which affects its plasticity and is not conducive to oil production; Too high is easy to scorch.

3.The adjustment mechanism of the cake is improperly adjusted. When the gap between the cakes is too large, the pressure of the press chamber is reduced, the residence time of the material in the press chamber is shortened, and the oil yield decreases.

4.The squeezing strip and snail are worn, the gap increases, and the pressing pressure decreases and affects the oil yield, so the severely worn parts should be replaced.

Soybean oil extraction process.

Soybeans are cleaned up and crushed Steaming and frying Pressing Filtering Crude oil Go to the refining workshop soybean cold (stupid pressing) squeezing process.

Soybean cleaning crushing Stupid soybean oil press filter crude oil to the soybean leaching process in the refining workshop.

Soybean oil cleaning, screening, winnowing, stone removal, magnetic separation, side by side mud mistake cleaning, dust removal, soybean moisture regulation, crushing, softening, rolling, soybean extrusion, soybean oil leaching, mixed oil treatment, mixed oil purification and preheating, mixed oil evaporation, mixed oil stripping, soybean ** (crude oil) filtration, hydration degumming, alkali refining and deacidification, decolorization, deodorization, refined oil.

The above process methods: the oil yield leaching is greater than that of hot pressing, and that of stupid pressing (cold pressing).

Nominal weight (kg) oil yield (%), oil production, cake and flower kernel 200 42-53 calculated according to 48% 96 102 Analysis of economic benefits of peanut oil press.

1. Take small-scale daily refining of 500 kg of machine-pressed crude oil (97% yield rate) as an example

1. The total comprehensive cost is 6778 yuan.

Among them: crude oil cost: 515 kg x 13 yuan kg = 6695 yuan; Electricity: 25 yuan 500 kg; Labor: 50 days;

Additives: 8 yuan 500 kg.

2. Output value: 500 kg x 16 yuan kg = 8000 yuan 3, profit = 7500 yuan - 6778 yuan = 722 yuan that is, 1222 yuan per day.

2. Take small-scale daily refining of 500 kg of hot pot oil (98% yield) as an example

1. The total comprehensive cost is 3141 yuan.

Among them: the cost of hot pot oil is 510 kg x 6 yuan kg = 3060 yuan Electricity fee: 25 yuan 500 kg Labor: 50 yuan Day x 1 person = 50 yuan.

Additives: 6 yuan 500 kg.

2. Output value: 500 kg x 10 yuan = 5000 yuan.

3. Profit: 5000-3141 = 1859 yuan, that is, 1859 yuan per day.

Industrial activities are to provide all sectors of the national economy with all kinds of raw materials, energy and technical equipment necessary for production, and also to provide people with rich and diverse means of life; Harvesting cotton and transporting timber in the air are agricultural production activities; The exploitation of oil and the extraction of soybean oil belong to the active rotation of industrial production

Therefore, c

The reasons are: the oil outlet valve has dirt or poor contact; The oil return is caused by poor contact between the screw plug of the inlet and outlet valve on the press and the valve seat or is not tightened; The wear gap between the small piston and the pump body is too large. The corresponding exclusion method is:

After dismantling and washing, it is ground to make it tight; Grind the oil valve plug and valve seat on the grinding press to make it close or tighten the screw plug; Replace the pump with a new one. Here's why:

The oil filter is blocked; If the oil is used for too long, there is sediment attached to the oil inlet valve, so that the throttle is not sealed; The oil in the tank is too thick or condensed due to weather; insufficient oil in the tank; The hydraulic pump is not vacuumed. The corresponding elimination methods are: clean the oil filter; Replace the oil with new oil or put the old oil out; Filter and clean the inlet valve, and grind it to make it fit well; Replace the thin oil, and the room temperature should be increased in cold weather; Fill the tank with a sufficient amount of fuel; Pull out the small piston, inject the oil and press again.

The reasons are: the safety valve is not sealed; Poor contact between the screw plug of the inlet and outlet oil valve and the steel ball; The oil pipe joints and the hydraulic cylinder screw plug and the oil inlet hole of the hydraulic cylinder are not tightened; The three-way return valve is in poor contact with the steel ball. The corresponding elimination method is: grind the safety valve to make it tight; Grind the inlet and outlet valves to make them tight; tighten the oil pipe joints and hydraulic cylinder plugs; Grind the return valve.

The reason is: poor contact between the oil outlet valve and the steel ball; The spring head is detached from the steel ball. The corresponding elimination methods are: grinding the oil valve and replacing it with a new steel ball; Enlarge the spring head. Here's why:

The temperature of oil steaming and frying is not suitable, the material temperature is too low, and the water content of the cake blank is too high; uneven thickness of cake blanks; When the bread is loaded, the bread is not stacked properly; Too fast and too strong when pressing. The corresponding elimination method is as follows: take an appropriate direction of steaming and frying, increase the temperature to more than 85, and the water content is less than 7%; Pay attention to the uniform thickness of the cake when making cakes; When loading the cake, the cake shirt should be folded correctly; Reduce the pressing speed appropriately.

The reason is: the leather bowl is wrongly loaded upward; The leather bowl is damaged. The method of exclusion is to reinstall the bowl and replace it with a new one.

The reasons are: the oil is not clean, and the dirt settles on the contact surface; The spring loses its elasticity; The adjustment screw is not loosened to the specified pressure; Often overpressure work, the steel ball will hit the valve. The elimination method of Xiangtong collapse Hu Ying is:

Disassemble and clean, such as valve port and valve pin damage should be grinded; Replace the springs; Re-adjust the screws so that the pressure reaches 40MPa; Re-grind the valve, replace the ball with a new one and take care to operate according to the operating procedures.

You're hungry and shut up, dear! According to your problem description: The oil bean machine is a common small household appliance used to quickly cook or simmer legumes such as black eyed peas, kidney beans, etc.

There are several steps to use the bean machine:1Shop for fresh legumes.

Fresh beans will taste better and be more nutritious. When purchasing, the main thing to look at is whether the beans are neat, uniform in color, and free of damage. 2.

Wash the beans and remove impurities. Put the beans in clean water and wash them once, and then twist them with the palm of your hand to remove impurities and broken beans. The washed beans can be placed directly on the limbs of the pot, or slightly blanching to remove the skin.

3.Heat the oil and pour in the beans after the right temperature. Generally, the temperature of larger beans such as black-eyed beans is controlled at 300-320 degrees Fahrenheit, and small beans can be slightly higher.

Pour an appropriate amount of oil into the pot, pour in the beans after the oil temperature is stable, and stir-fry until the surface of the beans has a color change. 4.Cover the pot properly and simmer.

Simmering is the process of simmering cooked or simmering beans so that the inside of the beans is completely soft and the appearance remains neat. During the simmering process, you need to stir-fry constantly to prevent the beans from over-charring or the bottom from turning black. Generally, it can be simmered in about 5-10 minutes.

5.Season and serve. According to personal taste, you can add an appropriate amount of sesame paste, chili sauce, honey and other seasonings to the mountain cracked bean machine to make the oil bean machine more fragrant and delicious.

In short, when operating the bean machine, it is necessary to pay attention to controlling the temperature, stir-frying frequency and simmering time, so as to make fragrant and soft beans.
