In his previous life, Zhou Yan often watched videos and had seen many short jokes about the steamed bun machine, so he was very familiar with the steamed bun machine.
The principle of the steamed stuffed bun machine is similar to the sausage-making process, which can be called "simple and crude": concentric circular tubes are used to transport noodles and fillings respectively to make "stuffed buns" sausage, and then the hydraulic clamping device below is used to "clamp"
"Get out the buns."
This kind of bun machine can make buns very quickly, but it has requirements for the dough to be fermented and not too hard. Therefore, after the buns are steamed, they feel a bit soft when eaten in the mouth.
Originally, Zhou Yan planned to directly use such a structure, but after designing it for more than half an hour, Zhou Yan accidentally remembered the master badges hanging in his head, felt a little ashamed, and then changed his mind.
In order to ensure the shape and taste of the steamed buns, Zhou Yan redesigned the core mechanical mechanism, changing the "steamed bun intestines" type mechanism into a lotus petal steel claw clamping buns type mechanism.
The core mechanism of the bun machine has twelve workstations above: three filling ports, three steel columns with non-chasing steel balls, and six empty workstations, each of which is a group of four workstations.
Corresponding to the filling port and stainless steel balls are twelve lotus-shaped stainless steel mechanical grabbers below.
After the stainless steel machine catches the dough sent from the feeding mechanism, it rotates to the next station, is lifted by the hydraulic device, and "meets" the stainless steel ball above.
After meeting, the dough is pressed into a bowl shape and stretched.
After that, the work station continues to rotate, and the lotus claws rotate to the filling opening to accept the fillings, and then the lotus claws grasp and seal the buns. At the same time, the stretched dough rebounds and clamps the fillings, ensuring the taste of the buns.
.
Then, the lotus claws move to the next station, the buns are taken out of the cycle, and the lotus claws continue to rotate to the next dough feeding port to receive the dough...
The cycle begins again and again.
Zhou Yan completed the design of the core mechanism in one morning, but it took nearly four days to refine the entire bun machine.
The design of a purely mechanical mechanism is not surprising, but the pneumatic mechanism on the steamed stuffed bun machine took a lot of effort from Zhou Yan: not only did the processing accuracy require high, but also the servo mechanism and control circuit had to be designed.
Fortunately, the core mechanism of the entire steamed bun machine is not complicated, and the control circuit does not need to be designed too complicated. Just a crappy 8086 microcontroller is enough to carry everyone.
Of course, Zhou Yan did not use all of the four days to make the steamed stuffed bun machine. He also used half of the day to make animation demonstrations.
At the weekend, Zhou Yan completed the finishing work and showed the demonstration animation to his uncle.
Li Yulin squatted in front of his notebook and watched the demonstration animation five times. After watching it, he turned around with joy and looked at Zhou Yan: "Shitou, you are really worth going to college!"
Li Yulin thought Zhou Yan was just talking about designing a simplified device for making buns, but what he didn't expect was that his nephew actually came to do it for real.
Of course, after watching the demonstration animation, Li Yulin was still a little confused and pointed at the computer screen: "Stone, we can't process this thing with our hands, right?"
"There are drawings!"
"That's good!"
The next morning, after breakfast, Li Yulin closed the shop early and took Zhou Yan around the surrounding machinery processing factories to distribute the drawings.
On Wednesday, the nephews and uncle moved the scattered drawings back to the shop together with the processed mechanical parts, purchased motors and pneumatic mechanisms.
"Stone, I'll leave the rest to you!"
Although Zhou Yan patted his chest and assured himself that he could be armed, Li Yulin still had no confidence in his heart.
However, seeing his nephew skillfully welding parts with a stainless steel welding machine, Li Yulin finally let go of his hanging heart.
Zhou Yan’s Kirin Arm, which has been trained for five or six hundred years in the virtual space, is not built after all. It only took one morning to assemble the machine. After welding the circuits prepared in advance, the whole machine was
It's finished.
Next, plug in the power, load the fermented dough and fillings, and press the mysterious button...
A brand new money printing machine was born.
Although he could only print small bills of a few tenths of a dollar, Li Yulin was still very happy.
"Stone, can you make this machine faster?"
"Of course you can," Zhou Yan pointed to the operation panel on the side, "Have you seen this number? The first gear is the slowest and the fifth gear is the fastest. If you want to adjust the speed, just press the plus or minus button!"
Li Yulin checked the "finished" buns and found that the buns were also made by a machine, but the appearance seemed a little different.
this……
"Shitou, why do these buns look so different?"
Zhou Yan turned off the main power supply, waited for the machine to stop, and pointed at one of the lotus claws: "This thing is the key to the formation of the buns."
Li Yulin frowned: "I remember doing more than twenty..."
Zhou Yan chuckled: "The claws are different, so the buns made are naturally different. Although the machine is very fast, it is still not very good if the customers notice it."
After testing for a while, Zhou Yan adjusted the program on the pneumatic valve and 8086 chip. After debugging again and solving the minor problems, the steamed bun machine was completed.
"Finally done!"
"Shitou, let's have a drink tonight to celebrate!" Li Yulin patted Zhou Yan on the shoulder happily, "Oh, by the way, isn't it a bit of a loss to only make one of such a good machine?
"
"Uncle, technology can also be sold for money!"
In the afternoon, Zhou Yan revised the drawings and technical documents, packaged them, and sent them to his eldest sister Wang Han in the capital.
After sending it out, Zhou Yan called his eldest sister and asked her to help apply for a patent...
"Boy, you have a lot of fantastic ideas in your head!"
"It's a joke," Zhou Yan smiled slightly, "Boss, just authorize the patent when you get the chance. It won't be of much use if I keep it here."
"Ruoshu's father owns a restaurant, doesn't he? There's no need for it?"
"Old Qin was playing tricks on me a while ago. He can use it if he wants. He can ask for it himself, otherwise there will be no need to talk..."
"You are so awesome! Okay, I have something else to do. I will let you know after the patent is sold..."
"Thanks!"
Originally, Zhou Yan had no intention of letting his cheap father-in-law Qin Fangyuan know about the bun machine, but he couldn't bear it. Qin Ruoshu often ran to the shop: Qin Ruoshu discovered the bun machine just two days after the shop started using it.
As for how it was discovered?
It's very simple. Zhou Yan, who usually stays in the kitchen, is actually selling breakfast with Li Yulin outside. On the steamer beside him, there are more and more steamed buns newly put on the steamer.
"Old Zhou, what's going on?"
In the small accounting room, Li Jinling, with her elbows turned outward, quietly brought Qin Ruoshu into the kitchen...
"How about it? It's awesome. My cousin did it himself!"
Qin Ruoshu naturally knows that this is a good thing, it can save a lot of manpower, and the buns are no different from handmade buns.
It would be great if Ruiyang Restaurant also had such a machine!
Envy is envy, but Qin Ruoshu was too embarrassed to ask Zhou Yan. When she was with Zhou Yan, she had to try her best to avoid talking about the bun machine...
"Silly girl! I feel so miserable that I never say anything!"
Zhou Yan shook his head, glanced at the huge billboard of Ruiyang Restaurant in the distance, and sighed slightly: "There are some things that need to be resolved as soon as possible!"
