Farmer's happy princess

Chapter 16 Simple and crude distillation tools
Gu Yunxi just observed the situation in the stove. There are two pots in this stove, one big and one small. She just wanted to do a small experiment today. There are not many mint leaves to be boiled. enough.

It's just that if you want to use the distillation method, you must open a hole in the lid of the pot later, and insert a conduit to let the steam out of the pot.

In ancient times, there were no plastic conduits, so they could only be replaced by small hollow bamboo tubes. The small bamboo is very flexible, and it can be bent into an arched shape and heated and baked. After cooling, the shape of the bamboo tube can basically be fixed.

At that time, the arched bamboo tube can be directly placed between the pot and the appliance for receiving the steam, acting as a conduit.

It just so happened that the original owner had many small bamboo tubes of sufficient length, so Gu Yunxi directly took a section and processed it with a very fast baking technique.

Fortunately, she has good skills, and she has mastered the baking heat very well, and she successfully set the shape of the bamboo tube in a short time.

Now that there is a pot and a pipe, Gu Yunxi found a large ceramic bowl to hold the steam. At present, he has found all the basic distillation tools.

It's just that the lid of the pot needs to dig a hole to insert the bamboo tube, and the peppermint oil is volatile, so the ceramic bowl also needs a lid.

Gu Yunxi thought over and over again, the lid of the pot is made of iron, so it is unreliable to use the lid to dig holes directly.

So she found two clean thick boards, and dug two small holes on them, just enough to fit the bamboo tubes. Later, one would cover the pot and the other would cover the ceramic bowl.

When everything was ready, she sterilized all the tools with boiling water, and then connected the pot and the ceramic bowl through bamboo tubes. The simple and crude distillation tools were barely there.

"Sister, I have already crushed the mint leaves, you, what did you make?"

Gu Lele came in from the door, saw a strange thing added to the stove, and immediately asked in confusion.

"My eldest sister wants to use steam distillation to extract peppermint oil. After heating, the water vapor can carry out the highly volatile peppermint aromatic oil."

Before Gu Yunxi finished speaking, Gu Lele was already stunned.

"Lele, give me the mint leaf shards, you watch, you'll know later."

Gu Yunxi didn't even know how to explain the process of distillation to this little kid, and she probably got confused if she talked too much, so let her read it by herself, and she will understand later.

Gu Lele really doesn't know what her eldest sister is talking about?So obediently, he handed over the mint leaf shards.

Gu Yunxi took the mint leaves, poured them into the pot, added a certain proportion of water, and covered the wooden board.

Before starting to light the fire, she took a large basin, filled it with cold well water, and soaked the steam-receiving ceramic bowl in it.

Originally, it was necessary to use the condenser tube to reduce the temperature of the oil-water mixture gas, so that the oil-water mixture gas could be transformed from steam to liquid state more quickly, but there was no condenser tube, so this method could only be used to replace the effect of the condenser tube as much as possible.

"Sister, Lele can help you get some firewood!"

Gu Lele scratched her head and scratched her head, she really didn't understand what the eldest sister was playing with?Just find what you can do.

"Ok."

When Gu Yunxi heard what Gu Lele said, she nodded immediately, and then she first used the little firewood left over from cooking by the stove to start a fire. She often went to picnics in her previous life, and she was very good at this.
