Rebirth 84 Everything depends on hands

Lu Peng's matter was settled easily. That night, under the supervision of Times Mall security, Jia Si emptied the shop. Jia Si knew in his heart that he could deceive Lu Peng, but there was absolutely no benefit to him in confronting Chen Feng.

Chen Feng has nominally terminated the contract with Lu Peng and taken back the store. He has not paid rent to Lu Peng and has not formed a new contract. He is being unreasonable. Jia Si, who moved out of Times Mall, sighed deeply.

, Jia Si, who originally wanted to take advantage of Lu Peng, was harmed by his own cleverness.

The next day, under the attention of the merchants, Lu Peng handed over the keys to the new tenants. Everyone knew that Chen Feng did not take back Lu Peng's shop at all, but was just helping Lu Peng.

Time passed quickly. After solving Lu Peng's matter, more than a month had passed. Seeing that the day to participate in the trade fair was getting closer, Chen Feng saw that there was no news at all from Teacher Zhong.

I couldn't help but become anxious and drove directly to Beicheng University.

Arriving at the laboratory, Teacher Zhong was leading a few students to do the final experiments. He watched Chen Feng leaving the laboratory and hurriedly came over.

After a brief introduction to Chen Feng, Chen Feng couldn't help but be surprised. In a short period of time, Teacher Zhong and the others actually researched everything they wanted. This speed was too fast.

Chen Feng looked at what Teacher Zhong had researched in front of him and couldn't help but admire it. He could actually create it just by relying on his own dictation and irregular drawings, and it looked quite beautiful.

At this time, Lin Xiaojun held something in the shape of a water cup in his hand and walked up to Chen Feng with a smile, "Brother-in-law, tell us, what are these things you asked us to develop?"

Chen Feng found out that what Lin Xiaojun was holding was an electric coffee bean grinder. Since he was participating in the World Electronics Exhibition, he had to come up with several products suitable for foreigners.

Following Lin Xiaojun's inquiry, everyone in the laboratory looked at Chen Feng. Due to tight schedules and heavy tasks, these people these days only know about research and development and production, and they don't even know what they are used for.

It's like the water cup in Chen Feng's hand. It has a lid on top, a cutter head inside, and the entire lower part is the circuit part. Although it was designed, no one knows what it is used for.

Chen Feng shook the thing in his hand to everyone, smiled and said to everyone, "This is an electric coffee bean grinder!"

Coffee bean grinder? A strange word appeared in everyone's mind, which means that this thing I developed is used to grind coffee? Isn't coffee just ready-made powder? What else can be ground?

Chen Feng then explained to everyone, "Foreigners like to drink coffee very much. Coffee powder is ground from coffee beans. Of course, they prefer to grind coffee beans manually, but the pace of development in foreign countries is fast and the pace of life is also fast. Although they like it but

There is no time to grind coffee beans manually, so I asked you to develop this electric grinder, which should be very suitable for them."

After listening to what Chen Feng said, everyone nodded. Teacher Zhong frowned beside him. This thing was researched and no one knew whether it would work. Since it was used to grind coffee, where could I find it?

Coffee experiment going?

"Boss Chen, we have researched it, but it doesn't work well. How can we experiment? We don't have anywhere to get coffee?"

Teacher Zhong looked at Chen Feng and asked in embarrassment. Chen Feng smiled in condolences. Isn't this simple? If there are no coffee beans, can we use soybeans?

"Teacher Zhong, don't worry, I have a solution," Chen Feng said, then turned around and called Lin Xiaojun to go to the cafeteria to ask for soybeans.

Soon Lin Xiaojun ordered a bowl full of soybeans from the canteen. Chen Feng reached out and grabbed a handful of soybeans and put them into the cup. Then he closed the lid, plugged in the power and pressed the start switch.

The blade hit the soybeans, and the soybeans collided with the stainless steel cup wall, making a huge noise, which made some students take a step back. After only a minute or two, the noise gradually became quieter. Seeing that the time was almost up, Chen Feng pressed the stop switch.

, opened the cup lid.

Everyone gathered around Chen Feng, stretching their necks curiously to look inside. They saw that the soybeans inside had been beaten into powder.

Lin Xiaojun was shocked for a moment, then grabbed the grinder from Chen Feng's hand and excitedly shouted to everyone that it was a success, and the entire laboratory burst into joyful laughter.

Teacher Zhong looked at the students' excitement and asked Chen Feng with a smile, "Boss Chen, you see that the soybeans are all powdered. I think coffee beans can also be used."

Chen Feng nodded, "Although coffee beans are a little harder than soybeans, there should be no problem judging from the current state. Lao Zhong, your research and development capabilities are really fast."

Teacher Zhong smiled and waved his hand, saying that without Chen Feng’s imagination and drawings, he felt that he would not have such a research and development speed.

"Boss Chen, what is this?" A female classmate pointed at another product and asked Chen Feng with a smile.

Chen Feng glanced at it and reached out to take the device over. "With an electric coffee grinder, this one is designated as an automatic coffee pot."

Coffee pot? Isn't that what makes coffee? Everyone was stunned after hearing this. Lin Xiaojun looked at the coffee pot in front of him, frowned and asked, "Coffee pot? Brother-in-law, they have a much longer history of drinking coffee than us.

Now, won’t there be anything to make coffee? Isn’t this a bit sloppy?”

Chen Feng looked at the coffee pot. It had a black plastic shell. When opened, there was a water filling chamber, a triangular inverted funnel, and a screen. After listening to Lin Xiaojun's question, Chen Feng smiled and said, "Of course they have it."

, they usually use siphon pots to make coffee, how can I describe this kind of thing to you."

Chen Feng didn't know how to explain the siphon pot to them. After all, in this era, only the cadres' children in Kyoto had seen the siphon pot.

Chen Feng, who was talking, asked for a piece of white paper, then picked up the pencil on the side and started drawing on the white paper. After Chen Feng finished drawing, everyone looked at Chen Feng curiously. This is where coffee is made.

Something? Why does it look so much like a beaker in a laboratory? There is an alcohol lamp underneath.

Chen Feng began to explain to everyone, "It's this kind of thing. The principle is very simple. The steam generated after heating increases the pressure, and then the pressure of the lower pot pushes the water vapor through the glass column to the upper layer, and uses the principle of soaking to extract the coffee liquid.

, after a certain period of time, remove the alcohol lamp below, the temperature below begins to drop, and the pressure also drops, showing a vacuum state, absorb the brewed coffee above, and use the filter of the upper pot to filter out the coffee grounds.

The coffee is ready."

After hearing Chen Feng's explanation, everyone nodded. Lin Xiaojun looked a little scornful. Who invented this design of taking off his pants and farting? It's so troublesome to drink coffee. Just rinse it with water.

"Siphon pots have advantages and disadvantages. It requires high technology and a tedious brewing process, and each person has his own technique. You can see that the coffee brewed by others using it is delicious, but when you use it yourself, you will be disappointed.

Not necessarily."

Speaking of this, Chen Feng patted the automatic coffee pot in his hand, "But our automatic coffee machine is different. You only need to pour the ground coffee powder into the filter, and then inject a proportion of water from the side.

It is burned into steam, smoked onto the coffee powder, condensed into coffee liquid on the coffee powder, and dripped through the filter into the coffee pot below."

"Although it cannot retain all the aroma of coffee, but in terms of time and hands-on ability, it is far superior to the current siphon pot, and coupled with the compact pace of life in foreign countries, I think it should be able to sell well."

After Chen Feng compared the two products, everyone nodded. Teacher Zhong's eyes changed when he looked at Chen Feng. He didn't know whether this thing could be a big seller at the exhibition, but Chen Feng was too quick.

, through the siphon pot, he made an automatic coffee pot in a different way. This brain...

"Boss Chen, your head is a computer, right? How...how did you come up with this?"

"The reason is very simple, it's because I'm lazy, haha!"
