Zeng Mishan certainly knew that the other party had gone to such great lengths to invite him over not just to drink coffee.
He knew exactly what the other party wanted. It was not a smart thing to hand over the best things as soon as he came in.
So he had to find a way to survive and see if Commons would play tricks on him.
"Boos, let me teach him a lesson!" Alia's voice rang out again.
Woman, you are so rude! Zeng Mishan's expression was moved, and he labeled the secretary dangerous in his heart.
After muttering inwardly, Zeng Mishan interrupted Alia and said seriously:
"The best coffee depends on its quinic acid content, which is 4,800 mg per liter. However, if it is overcooked, the tannins will be filtered out, and the bitterness will be too much, making it unpalatable. If it is vacuumed and the temperature is controlled within 92 degrees Celsius..."
"Shut up! You're looking for death." Alia felt that her position was challenged. She had always been responsible for Boos's coffee.
This damn yellow guy actually questioned whether the coffee he made was tasty. I want to beat him to death.
At this time, Alia had already sentenced Zeng Mishan to death in her heart.
Ignoring Alia's fierce eyes, Zeng Mishan complained in his heart: "Little girl, you have narrowed your path. I advise you to be kind. Later, I will make you cry for daddy in pain!"
But he said loudly, "Choose coffee beans from Sumatra. After grinding, I will use a round-bottom flask, condenser, and vacuum extraction to make a pot of premium coffee. I will let the warden drink the most unforgettable coffee. This will be a welcome gift."
Zeng Mishan was gambling. He needed to show off more skills. Only in this way could he raise his value and impress the other party.
"Take him to the laboratory. I'm eager for a surprise. If Mr. Zeng lies to me, I will put you in a concentration camp." After Commons finished speaking, he showed a mysterious and evil smile.
Concentration camp, what is that place?
Is this a place where a bunch of grown men hang out?
Zeng Mishan couldn't help but squeeze his buttocks. He had read a report before that said concentration camps abroad liked to pick up soap and fight with bayonets. The thought of it made him shudder.
If you look at the back of Zeng Mishan, you can see that he walks like a dog with its tail between its legs.
There's a touch of horror in the funny...
Zeng Mishan, walking with his head covered, was led by the prison guards and soon arrived at a new place after making many turns.
Damn, there really is a laboratory in this damn place.
It’s a big investment!
As far as the eye can see, this laboratory is about 100 square meters, which is quite good.
Unlike the high-tech ones in the movies, it is a bit old-fashioned, with a lot of things. Large objects and various experimental instruments are placed neatly and orderly, while small objects, utensils and tools are messy.
They don't even know how to clean up. It's obvious that a bunch of careless guys have used this place.
If it were his own student, he would have scolded him and made him copy it a thousand times in 5S on the spot.
Zeng Mishan sniffed and looked at Commons strangely. There was still a strong odor lingering in the laboratory.
The smell made him feel a little familiar. He kept the answer in his heart and chose to continue observing.
Reactors, mixers, refrigeration equipment, filter tanks, dehydrators, heating devices, balances, scales, funnels, dehydrators, stainless steel barrels, glassware, steel tanks, metal molds...
There are also a large number of filter papers or many hydrogen cylinders, and there are ventilation and smoke exhaust facilities above the head.
For an old hand, one can tell at a glance that there were traces of drug production here.
"Mr. Zeng, please start your performance." He stretched out his hand and made a gesture of invitation. On his own territory, Commons didn't care about being discovered.
Zeng Mishan put on a white lab coat and gently touched various utensils and instruments.
He is passionate about invention because the laboratory has the magic power to turn decay into magic.
This is where miracles happen.
Zeng Mishan asked for his glasses back, but he never thought he could get them back.
Looking at Alia's expression, she looked disgusted.
Blondie, you have a lot to say about me!
Don't give me a chance, or I'll make you scream! No, I'll make you scream!
"First develop, then I'll fuck her to death later." This is a phrase my son often says when playing games, and Zeng Mishan decided to borrow it.
After taking the coffee beans, Zeng Mishan instructed the reluctant Alia to grind the beans. He had only one requirement: the bean powder weighed 288.99 grams and the weighing accuracy must not exceed 1 microgram.
This is the data he obtained after trying many times.
Arya rolled her eyes at him. If anyone could read lips, they would know what Arya was saying: Are you a devil?
If Boos hadn't had such high expectations, Alia swore she would never help out.
While Alia was grinding the beans, Zeng Mishan began to select clean and suitable utensils, such as siphon pots, glass flasks, measuring cups, culture vessels and other utensils.
After the cooking equipment was connected, Zeng Mishan took out some coffee beans. He wanted to purify some caffeine for later use.
Adults should limit their daily caffeine intake to less than 400 ml.
Zeng Mishan asked Commons, and he said his habit was to drink two cups in the morning and two cups in the afternoon.
What Zeng Mishan needs to do is control caffeine and keep it at the critical point.
He first used the siphon principle to extract the coffee pulp, distilled it to recover excess alcohol, poured the concentrated pulp into calcium oxide, stirred it continuously, and controlled the moisture and residual alcohol.
Continue heating to allow the caffeine to sublime and crystallize. After heating, you will find thread-like transparent crystals on the filter paper.
This way, high-quality caffeine is extracted.
There are many ways to extract caffeine, the most common one is using a separatory funnel and extracting by adding dichloromethane, which these laboratories do not have.
Many people don’t know what dichloromethane is. It is used in some dental local anesthesia.
