Chapter 86: Distillation (below)

　　 The rural village where Chen Fan lived when he was a child had a winemaking workshop with a history of over a hundred years, and the aroma of the wine would drift with the wind for more than ten miles when a new wine came out. The friends in the village also like to go to the workshop to play, and they are very curious about the big wine tanks and big wooden barrels.
　　I got used to seeing each other later and understood many principles.
　　 For example, Chen Fan knows that solid distilled spirits are divided into three categories: first wine, middle wine and tail wine.
　　 The first out is the first wine, with an average degree of 70 or 80 degrees. The taste is thick, spicy, nasal, and slightly poisonous. It cannot be drunk as alcohol. It can be used for medical alcohol disinfection after further distillation.
The middle part of the wine is called middle wine. The temperature of the wine steam decreases and stabilizes when compared to the first wine. The aroma and nutrients of the raw materials begin to evaporate and mix with the wine body. The degree is generally 70 to 20 degrees. Slightly sweet, mild, original fragrance, is the most essential part of the wine, but also the part suitable for drinking.
The final outflow of the tail wine has greatly reduced its body weight, and the mixing ratio of water and fat is seriously unbalanced. Water accounts for more than 85%, and the degree is basically below 20°. The taste is sour, bitter, heavy in water, and turbid, which is inferior. Wine is not suitable for drinking.
　　 However, what Chen Fan uses is to directly distill and purify the liquor puree, which is regarded as a double distillation method, so the first wine can also be consumed directly. If you distill the first wine a few more times, you might get the legendary "water of life"!
　　 Chen Fan was staring at the distilled clear liquor dripping into the wine jar, considering whether to distill a few more times, suddenly a big hairy hand reached out and wanted to grab the wine jar.
　　 Chen Fan's eyes were quick and his hands were quick, he slapped off his paws, then turned his head and glared at each other.
　　 The White Ape King was taken aback for a moment, and he was going to be angry with his teeth!
　　 Chen Fan pierced his finger and warned softly: "This wine must not be disturbed, otherwise it will become sour!"
　　 The White Ape King immediately closed his mouth and squatted aside obediently, sniffing his nose continuously.
　　 quickly filled a large pot of wine and only half a jug of wine was distilled.
　　 Chen Fan shook his head slightly, disappointed with the tightness of the still.
　　 "What are you shaking your head? Isn't this wine steamed out?" White Ape King asked quietly.
　　 Chen Fan said helplessly: "This wooden barrel is too tightly sealed, and only half of the wine is distilled from the three jars of puree. At least half of it has evaporated."
　　 The White Ape King felt distressed, and asked, "Is there any way to increase the sealability?"
Chen Fan thought for a while and said, "After all, this wooden barrel is spliced ​​by pieces of wooden boards. No matter how tightly fitted the seams are, it can't stop the air leakage. If a wooden barrel can be carved out of a whole piece of wood, the uncertain sealing will be better. Well, I remember there is a huge wood forest to the north."
　　 "This king is going to fetch it for you!" The White Ape King slammed into the air.
　　 Half a quarter of an hour later, the White Ape King brought back a giant tree that was nearly 300 meters high and could only be hugged by dozens of people.
　　 "How about this tree? If it is not enough for the king, go and cut another one!"
　　 Chen Fan said: "Enough is enough, remove the extra branches, and then cut them into a log with a height of up to ten feet, and then hollow out the middle."
　　 "You little bear spirit dare to instruct this king?" The white ape king bared his teeth.
　　 Chen Fan shook a half of the distilled spirits and asked, "Hurry up, do you want to drink it?"
　　 "Hmph!" The White Ape King snorted proudly, but he obediently followed Chen Fan's instructions to cut the entire giant tree into sections of logs, and then peeled and emptied them into barrels.
　　 The Demon King is the Demon King. The work that originally took at least ten days to complete was completed in half an hour.
　　 Reinstalled the log vat, and Chen Fan tried to boil water again, and found that the sealing performance is much better than the spliced ​​wooden barrels, and there is no steam leakage...
　　 "This airtightness seems to be a bit too good, you have to install a pressure relief valve." Chen Fan took out the design drawings and began to modify.
　　 "What is a pressure relief valve?" White Ape King asked curiously.
　　 "It is the valve that prevents excessive pressure in the barrel." Chen Fan explained casually.
　　 "What happens if the pressure is too high?"
　　 "It will explode."
　　 "……"
　　 "Don't be nervous, it will explode only with iron buckets, we are wooden buckets, at most it will only be blown off..."
　　 Boom! ! !
　　The huge log barrel suddenly soared into the sky like a rocket!
　　 "Look, I'm right."
　　 "Hmph! This king has never seen anything in the human world before!"
　　 "Where are you going, King?"
　　 "The king's back pain has committed again. Go back and rest a while, you continue to make wine, and you will have great rewards for the king."
　　 Chen Fan shook his head speechlessly, looking at the silhouette of the White Ape King who was fading away.
　　 Originally wanted to take advantage of the cold weather to invite the White Ape King to have a hot pot, it seems that this king has no such blessing.
　　 Although the log barrel was bombed by high-pressure steam more than ten meters away, because it is made of high-quality cedar wood that is as hard as steel, the entire barrel is intact and can be used again after installation.
Then Chen Fan opened two small holes on the top of the wooden barrel, and used a wooden plug to block it as a simple safety valve. When the steam in the barrel exceeds the pressure, the wooden plug will be opened to release the steam and release the steam into the barrel. Reduce the pressure ~EbookFREE.me~ Then Chen Fan replaced the animal skin tube connected to the cooling barrel with a sheet metal tube with better thermal conductivity, and tied a large number of heat sinks to the sheet metal tube to help the high-temperature steam in the tube to be more efficient. Cool down quickly.
　　 Then Chen Fan tried to boil a few more pots of boiling water, and the original wooden barrel was not blown up to the sky again, so he started distillation.
　　 Time flies to the next spring.
　　 Chen Fan directed a group of rat spirits awakened from hibernation to help plant the seeds.
　　 New fields are reclaimed on the edge of the river valley near the forest, which not only guarantees the water source but also avoids the activity area of ​​large dinosaurs.
　　 In fact, the most fertile water and soil in the river valley is the two banks of the river in the central area. Unfortunately, there is the diplodocus site, and there are often fierce water animals in the river, which is not suitable for pioneering.
　　 Of course, if Chen Fan is willing to completely ask the cheap brother to help clean up these dinosaurs, but this is bound to destroy the ecological environment in the valley.
　　 But he just wanted to cultivate a few acres of land to be self-sufficient, and he didn't think of a science and technology tree to develop industrial civilization, so he did not have the idea of ​​developing the river valley.
"Do you still farm?" The knowledgeable White Ape King suddenly appeared beside Chen Fan, looking curiously at the mouse spirits who were busy in the field: "No wonder you refuse to stay in this king's Pansi Dong, I was planning to slash and burn here."
　　 Chen Fan said with a black thread: "My lord, please stop tampering with the name of Tongtian Peak. This will make it difficult for the little demons below."
　　 "This king is happy." The White Ape King hummed, "Maybe the immortal Pansi will pass by here and give this king three moles!"
　　 "Just be happy." Chen Fan looked speechless, turned around and said: "The wine is distilled, and there are three flavors. I named them ‘Water of Life’, ‘Drunken Life and Dream of Death’, and ‘Green Bamboo Leaf’."
