First, analyze the known information: 8/9 Jin of soybean can squeeze out 1/3 Jin of oil. Here are two quantities: one is soybean and the other is oil. The mass of soybean is 8/9 kg, and the mass of oil is 1/3 kg.

Next, look at the question: The first question asks 1 kg soybean how many kilograms of oil can be squeezed out? If you are asking about oil, use the quality of oil as a dividend.

The mass of oil is 1/3 kg, and 1/3 is the dividend. 1/3 divided by soybean 8/9 kg = 1/3×9/8=3/8 (kg).

Oil pressing, an agricultural scientific term, is the process of converting crops such as peanuts into oil.

The ancient oil press paid attention to technology, and technology paid attention to the accumulation of experience. Every working procedure of the traditional ancient wood press is exquisite and has its key points, such as temperature, strength and time.

The ancient complex oil pressing technology has not faded because of the passage of time, but has undergone continuous improvement and refinement, condensing the wisdom crystallization and innovation of generations of folk craftsmen.

The ancient method of oil extraction pays attention to technology, while technology pays attention to the accumulation of experience, traditional

Every process of ancient wood pressing is very particular, and it has its key points, such as temperature, intensity and time.

Peanuts are made of high quality peanuts, with rich aroma and full particles. When purchasing, they must undergo strict sampling and inspection to ensure the high quality of peanut raw materials and the natural fragrance from raw materials. And the unique sealing technology is adopted to push the authentic secret frying technology to the peak, fully retaining the original flavor of peanuts.

The low-temperature precipitation filtration control method keeps the nutrition and fragrance of peanut oil to the maximum extent, and filters the original fragrance without adding it. In the production process of filtration, low-temperature crystal growth is adopted, and low-temperature filtration is carried out with filter paper and filter cloth to remove easily precipitated phospholipids, phosphorus-free gum, high-melting saturated fat and other components in peanut oil, so as to ensure the purity of peanut oil and raise the fragrance to a new level.
