It takes a lot of time and materials to prepare to make pottery, and the process is too complicated. When Tinki's koji was ready, the pottery condenser tube had not yet come out of the cellar, and Tinchi could only target other parts.

It took less than two days to weave the funnel-shaped lid according to the size, and there was a five-centimeter-diameter opening on the top as an outlet for steam. Then he selected a bamboo with a diameter of 10 centimeters, cut a three-meter section of bamboo tube from the middle, and cut off a half-meter-long bamboo tube from each end.

After the bamboo tube is ready, a 10-centimeter-long bevel cut is made at one end of the half-meter-long bamboo tube with a saw, and the same notch is sawed out for the two-meter-long bamboo tube. These notches need to be aligned together to ensure that they fit together and that they do not show air or show less. Therefore, he chose to use the same bamboo as a combination to minimize the problem.

As for how to anastomosis the incision, use the bone glue from the carpenter's side for bonding, and there will be no problems. However, the bone glue will change when it is exposed to hot and humid gas for a long time, so the adhesive can be replaced every once in a while.

The progress of the condensation barrel can also be made, and the carpenter is even more handy, and the time does not take long, but the barrel hoop made of bamboo skin is more time-consuming, because it is the guarantee of the quality of the barrel. The condensate bucket was made, and a hole of the same size as the condenser tube was dug at the edge of the bottom of the bucket. A corresponding lid was attached to the barrel, and an eye was drilled into the lid, the same diameter as a steam pipe.

It's just that there is a big difficulty in the connection between the steam pipe and the condenser pipe, the pipe size is not the same, and I don't know how to connect.

And at this time, Ding Qi made a move.

He took out his axe and smashed a piece of copper into a copper sheet about two millimeters thick, cut it and made a funnel. The size of the upper mouth of the funnel and the steam pipe is the same, and the size of the lower mouth and the condenser pipe are the same, and this connection problem is finally solved.

It's just that the scene of Ding Qi making a funnel was discovered by the blacksmith of Tongcun, and he studied on the spot, and he slowly learned it, and carried forward the method of making various tools with copper skin, and carried out various innovations, even his master mallet studied hard. This man was a slave who had no name when he first came to the Ding tribe. He followed the blacksmith mallet in Ningcheng to learn the art of casting, and was later given the name by Ding Qi: casting. Originally, he wanted to give this person a name, but he felt that this name was too expensive and did not dare to give it to him.

After the whole set of distillation equipment was made, Ding Qi first tried it. The bronze pot used in Ningcheng is relatively small in diameter and is made using stamper casting technology, but if you want to make a larger bronze pot, you will never succeed. The main thing is that when pressing the mold, the weight of the sand is too large, and it falls down as soon as it is lifted, so that the mold is not formed. Ding Qi could only hope to increase the size of the bee colony, get more beeswax, and use the lost wax method to cast larger bronzes.

The clay pot is boiled, and a large amount of water vapor passes through the pipe into the condenser tube, which is submerged in the water, and after a short time, a stream of water flows out of the lower end of the condenser pipe and into a clay pot on one side. This is the legendary rootless water, which is distilled water. If the fermented fermented fermented ferment

The distillation unit was initially successful!

At this time, the large area of kudzu was excavated about less than half of the scale, mainly because the continuous autumn rain in the early stage affected the excavation progress, and the muddy ground and wet

environment has slowed down.

The kudzu that was dug out was beyond Ding Qi's imagination. These kudzu roots, which have grown for an unknown number of years, grow thick and strong, all in whole pieces, and some even grow as thick as a large pumpkin. Fortunately, these kudzu roots did not run away or become human, otherwise Ding Qi would have suspected that these kudzu roots have become essences.

Ding Qi had a portion of kudzu cleaned and sliced, then cut into thumb-sized cubes, and steamed them. The purpose of steaming in a pot is to make it ripe and make it easier and faster to ferment than raw kudzu; The second is to remove the miscellaneous smell in the kudzu root material and decompose some of the harmful substances in it.

After steaming, the kudzu is immediately put out of the pot and spread on the bamboo plaque to cool, and after cooling, the kudzu is put into the pottery jar sterilized with boiling water, sprinkled with koji, injected with some well water, and the pottery jar is sealed after stirring evenly.

Since there are no good sealing materials, such as 21st century plastic film, Ding Qi can only ask a carpenter to make some wooden lids, and then cover the inside side with a layer of sterilized deerskin.

Ding Qi prepared a total of 10 clay jars, each large clay jar filled with steamed kudzu dice, which was thoroughly stirred with koji and began to ferment.

This link is very important, especially the temperature must be properly controlled, not too high nor too low, probably like the outdoor temperature in spring and April. Therefore, under the current temperature link, Ding Qi ordered people to seal the outside of the wooden shed where the wine is made with a layer of animal skin, so that the temperature in the wooden shed can reach the ideal temperature for fermentation.

Next, there will be a heavy manual labor link. Of course, for Ding Qi, he only needs to move his mouth to instruct his subordinates to do it. Every day or two, Ding Qi would enter the wooden shed to feel the temperature in the shed, and if the temperature did not reach it, he would have a charcoal brazier to heat it up. At the same time, open the lid to check the fermentation of kudzu in the pot.

During the fermentation process, the contents of the clay vat will constantly produce gas bubbles, so it needs to be manually stirred every other day or two until no more bubbles are produced. However, after the bubbles are over, the stirring should be continued every two days in order to allow the kudzu root to fully ferment, so that the starch inside can be converted into sugar, and then the sugar will be broken down into alcohol.

If the temperature is too high, the kudzu mixture in the pot may become smelly, and the fermentation rate will be reduced if the temperature is too low.

During the fermentation process, Ding Qi worked non-stop and began to focus on how to make kudzu root powder. According to Ding Qi's estimates, the dug kudzu has exceeded 10,000 catties, and even more, which greatly exceeds Ding Qi's expectations. Although he had arranged for stonemasons, masons and others in Tongcun to speed up the production of stone grinding and bamboo plaques for filtration, and had people make fifty or sixty large pottery jars in advance, he still felt that these were not enough.

However, when the weather is getting colder and colder, it is no longer realistic to make pottery jars in batches, so Ding Qi can only suspend the excavation of kudzu and turn to the extraction of kudzu powder. Fortunately, this work can be processed, and the whole process of cleaning, slicing, dicing, refining, water injection, filtration, sedimentation, and drying is carried out in an orderly and fast manner under the command of Ding Qi.

Ding Qi has heard that wild kudzu has a low powder yield, as the saying goes, it is called looking at the face, which means looking at luck. Artificially planted kudzu has a high pollination rate, about 25%. But this wild kudzu is the last to come out

The fan rate scared Ding Qi a lot, close to 20%.

This is a very high yield, which Dingchi can only attribute to the long growth cycle of these kudzu roots. In a slightly barren place, the ability to grow such a high rate of kudzu can only be explained by the long growth cycle. The thinnest of these dug kudzu roots is also ten centimeters thick, I really can't imagine how long these kudzu roots have grown, Ding Qi is really worried that a goblin will pop out of it!

The autumn rains were followed by a sunny day, the sun sprinkled its rays on the whole world, but it could not stop the cold, and the minimum temperature during the day was close to freezing, still in the process of declining day by day.

The weather is good and the mood is good. Ding Qi gave everyone a rare day off, so that White Fang could take everyone to rest comfortably. And himself, with the two men, began to prepare for distillation.

At this time, in the clay jar, the kudzu root has been fully fermented, the moisture content in it has been reduced a lot, the sake has a moderate amount of dryness and wetness, and the liquid will not seep out if it is gently grasped in the water, and if you grasp it hard, there will be liquid flowing down the gap. In addition, the kudzu fermented distillery, which originally occupied about three-fifths of the clay jar, is now almost on the edge of the jar, and the purpose of full fermentation has been achieved.

The rich aroma of wine fills every inch of space in the wooden shed, and there is a hint of sweetness mixed in it, which makes people feel intoxicated. The two people around Ding Qi showed an intoxicated expression, and were kicked out of the wooden shed by Ding Qi one by one.

"Exam! Exaggerated than me! ”

However, because Ding Qi was the first time to carry out filler fermentation, the temperature control of the heat was still a lot worse, all based on feeling and experience, in the end, only seven pottery vats were successfully fermented, and the other three clay jars in the kudzu fermented distillery directly sour and smelly, resulting in fermentation failure.

But this is already a very good result, but the hateful thing is that Ding Qi is not satisfied, and hopes to achieve 100% success, so that the other traversers want to beat him, but unfortunately he can't wear this world.

In fact, at present, the fermented fermented ferment At this time, the liquor could only be regarded as a type of rice wine, but Ding Qi's goal was to distill a high degree of liquor.

Outside, under another wooden shed, a complete set of distillation equipment is already in place. Fill the pot with enough water, then put in a large grate made of bamboo slices, put a layer of weeds boiled in boiling water on top, put the steaming bucket, and then put the loose kudzu fermented rice into the steaming bucket, cover it, fix the steam pipe, and connect it with the condenser pipe.

At this point, the entire condenser tube is already fully buried in the cold water of the condensate barrel.

During the fermentation of the kudzu root, the potter has fired the condensed tubes of the pottery. A total of six condenser tube blanks, and finally three were successful, with a success rate of 50%. It's just that Ding Qi made sure that he succeeded the first time, and used the condenser pipe made of that steel pipe as a condensing device.

Under the blazing flame, the water in the clay pot quickly boiled, and a large amount of water vapor passed through the thick fermented rice in the steaming barrel, quickly heated it, carrying the contents of alcohol into the steam pipe above, and quickly entered the condenser tube, and after a while, a strong aroma of wine was emitted in the air along the flowing wine.
