Prosperity in the world is beneficial; The world is bustling, all of which are benefits. Breast-squeezing in rural areas is to earn processing fees to support the family. How can his family live without making money? Isn't it obvious? Sometimes there is no extra processing fee for milking breasts in rural areas, and almost all oil mills will do so. Because whether it is peanut or rape, the oil is only a small head, and the big head is bean cake or oil residue after oil pressing. If you only want oil, instead of bean cake and oil residue, you can use it instead of processing fee.

The value of bean cake and oil residue may be greater than the processing cost. That is to say, if you only squeeze oil and don't pay the cost of bean cake, frying and processing, you may suffer invisibly, but it doesn't matter if the quantity is small. If there are many piles in the oil mill, you can sell the piled bean cakes or oil residue to those in need. So to be fair. If there is a lot of fuel to be extruded, the processing fee and bean cake or oil residue can be calculated separately, which can be clearly defined in advance, and it is reasonable to refund more and make up less. In fact, if you are honest, you will do the same for big customers.

Our village also has two milked breasts. Every year, many people in our village take their own peanuts and pick camellia to extract oil. We also charge processing fees for milking here. The milkman said that we can offset the processing fee with oil cakes. Therefore, many villagers use oil cakes to deduct processing fees. Later, over time, the oil cake became the owner of the extrusion room, acquiescing that farmers did not have to fry oil to pay for processing. My family collects peanuts 100 kilograms a year, and 100 kilograms of peanuts can produce about 40% oil. My peanut oil processing fee is not expensive, 10 ~ 20 yuan, but every time I go to extract oil, I will deduct the processing fee with peanut oil cake.

Some villagers' peanuts are not too salty, so they only pay a few processing fees, and they can also use peanut oil cakes to offset the processing fees. At first, the boss of the oil mill didn't know what to do with the oil cake, but later he learned that the oil cake sold more than our processing fee, so the boss of the oil mill didn't charge our processing fee. Moreover, we go to squeeze tea seed oil, and the owner of the oil mill does not charge processing fees. He just wants to eat our pancakes. The oil cake squeezed from Camellia oleifera seeds is more valuable than peanut residue. A camellia oleifera cake can sell 5 yuan 1 kg, and each cake can sell 4 ~ 5 kg. Then, Liu Bing camellia can be sold for more than 20 won.
