Although the structure of the wedge oil press is simple, it is not so easy to turn this big tree trunk into a qualified wedge oil press.

　　 Apart from anything else, just taking out the squeeze cabin and the oil cake cabin from this tree trunk is a very complicated job.

　　 If you have a complete set of modern tools in later generations, you can play with this big tree trunk as you like, and you can choose any of three hundred and sixty-five positions.

　　 But in this era, in the high tree tribe lacking all kinds of woodworking tools, it is really not an easy task to pull out a press bed from such a large trunk.

　　If the squeeze chamber in the press bed is rectangular because it is a good idea, then taking out the round oil cake chamber is a huge challenge for the old wood family.

However, Laomu is indeed the old carpenter who has held the title of the first carpenter of the Gaoshu tribe for decades. After discovering that it was almost impossible to pull out a circular oil cake cabin from the trunk of the tree, Laomu The family immediately decided to solve this problem from another aspect.

The main function of the 　　 oil cake compartment is to hold the oil cake, and then squeeze out the oil contained in the oil cake through the squeezing force at both ends. Therefore, for the oil cake tank, there is almost no pressure around it. The main stress points of the oil cake tank are at the two ends of the oil cake tank. These two parts are the most difficult parts.

　　 After figuring out the working principle of the entire oil press, Old Wood actively sought to change it.

He suggested that the upper part of the oil cake compartment should be sawn. Anyway, the stress point of the oil cake compartment is not in that position. After sawing, a semi-circular oil cake compartment can be taken out from the lower part of the tree trunk and the sawed upper part is at the same time. Half of it also took out a semi-circular oil cake compartment. In this way, when you put the oil cake, open the upper part, after the oil cake is finished, cover the upper part, and finally block it with a thick wooden stick, then use it as usual.

　　 Anyway, the squeezed oil will always drip from below, not from above or from the side. This is absolutely no problem.

　　 Shixiong agreed to this method, so after five or six days, the oil press was successfully completed.

　　 Although this oil press is not the same as the one in the fourth grandfather of Shixiong, Shixiong estimates the effect is the same.

　　 Now that it is done, the next step is to experiment to see if this oil press can squeeze out oil.

The 　　 oil press is placed on a sturdy wooden base. These wooden bases are made of logs with the thickness of the thigh, which are enough to support this heavy wedge oil press.

　　The reason why this old-fashioned wedge oil press uses such a thick trunk is mainly because the wooden wedges smashed into the oil press will produce a great squeezing force when the oil press is working. If you squeeze the body thin, it is very likely to be broken.

　　 That's why this old-fashioned wedge oil press is made with very thick tree trunks in order to prevent it from breaking apart. After all, the thicker the trunk, the stronger it is.

　　 On the evening of the first day of the experimental oil press, snow flew in the sky again. Although the snow flakes this time were not as big as the first heavy snow, the snow was bigger than the first snow. Snowflakes fluttered all night, but there were still no small ones by the next morning.

　　 And looking at the sky, this snow is estimated to be at least still the next day.

The people of the 　　 tribe got up early in the morning, first cleaning the snow on their respective roofs, and then began to clean the snow in the tribe. Finally, after having breakfast, they gathered at the oil press.

　　 That's right, this house, which was opened up by three wooden houses, has been named "Oil Pressing Workshop" by Shi Xiong.

　　 people are very curious about how the oil press is squeezed out. Even Ferguson came to the oil press with hard bones and rabbit mouth. It was too cold, and there was no way to experiment in heavy snow, so Ferguson simply took a day off.

The people in the 　　 tribe have never eaten oil, and the fat from the captured prey will be refined into oil, so fat is not a rare thing for the people of the Gaoshu tribe.

　　 It is rare to be able to squeeze the oil out of peanuts.

　　 So many people came, and Shixiong was also very happy. Oil extraction requires a lot of manpower, and these clansmen who watch the excitement can just help.

　　 Under the command of Shi Xiong, the earth stove that had been built a long time ago ignited the fire, and a large iron pot was built on it, with sand placed in it, and about a hundred catties of shelled peanut kernels.

　　 To squeeze peanut oil, the most important process is "one frying and two steaming", of which frying is the most critical step.

　　 When squeezing oil at the fourth grandfather’s house, most of the villagers in the village used rapeseed to squeeze oil. In that era, no one was willing to use peanuts to squeeze oil.

　　 Regardless of whether it is rapeseed oil or peanut oil, it must be cooked before pressing. When frying rapeseed, you don't need to add sand, just put it in the pot and fry it, but you must add sand to fry the peanuts, otherwise the peanuts will not be cooked even if the outside is fried. Only by adding sand to fry, can the peanuts be heated more evenly, and the heating time will be longer, so that the peanuts can be thoroughly cooked.

　　 Shixiong took a big shovel and stood on a big rock next to the stove, UU Reading www.uukānshu.com began to fry peanut kernels with a shovel.

　　 The peanut kernels must be fried, and the moisture inside must be fried as much as possible. The standard is that they are fragrant and not burnt.

　　The step of speculation is a step that requires a lot of experience. Generally, ordinary people can't do this kind of work, and that requires an experienced master to speculate.

　　 Back then, Shi Xiong was able to fry the rapeseed oil for the fourth grandfather, so he can be regarded as an experienced master, so he has to cook it himself. He was worried about other people, just a little peanuts, it would be troublesome to fry a pot.

　　 Put out the fire, and then pass it through a sieve to remove the sand and leave the fried peanut kernels.

　　 Then Shi Xiong greeted several people from the tribe, put the fried peanuts into the stone mill and began to grind them. Taking advantage of this gap, Shi Xiong began to fry the second pot of peanuts.

　　 It’s one pot and one pot, and the ground peanut kernels will be put away, wrapped in cotton cloth, and placed in another steamer for cooking. Once you have made up a big pot, turn on the fire and start steaming.

　　 After the ground peanut kernel powder is steamed to a certain temperature, the powder is formed by hand, and then it can be taken out and pressed.

　　The so-called pressure plate is to make oil pancakes.

　　The specific method is to put the right powder into a container made of iron rings and dry thatch, and then compact it.

　　 The iron ring was cast by the stone bears compared to the diameter of the oil cake cabin. It was slightly smaller than the diameter of the oil cake cabin and was about ten centimeters wide. Spread a large amount of dry thatch in the iron ring, then put the right powder into the thatch, and then cover the thatch that has grown out, and then ram it with a wooden hammer.

　　In the end, these powders will form a pancake wrapped in iron rings and thatch, and put them into the pancake compartment together with the iron rings to prepare for pressing.

　　 This process is "one squeeze".
