Chapter 78 Innovation in Craftsmanship

Friedrich asked Schmidt and the others to adjust the machine slowly, and he and Koehler had a look at the paper being trial-produced.

"What do you think of those two machines?" Frederick asked.

Koehler replied: "I think it's very good. Schmidt is also willing to pay on credit. He said it was done with the school's research funds and can be paid back slowly."

The corner of Frederick's mouth twitched.

They walked to a pile of thumb-sized wood chips, and Koehler said: "These are sawed out with a sawing machine, which is time-consuming and labor-intensive compared to machines."

Frederick nodded, squatted next to the wood chip and picked it up for observation.

Koehler continued: "The reason for the graying of the paper we produced last time was found. The pine bark inside the wood chips was not cleaned."

"Schmidt's machine can just remove the bark first, and the paper can be whiter later."

Frederick nodded, stood up, and went to the side to watch the workers sort out the wood, taking out all the dark ones.

The thin wood chips picked out were taken to the stove outside and steamed in a large pressure cooker.

Frederick found that the workers poured the water after steaming the pine wood in the pressure cooker into the water tank to collect it, and put the lid on it. He asked curiously, "What is this for?"

"There's pine oil in the water that cooks the pine chips, which is an unintended by-product that happens to be used in printing inks," Koehler explained.

Frederick nodded in satisfaction. This was not the case before. In the beginning, Psyche’s method was to steam buns like steamed buns, but now they are steamed in a large pressure cooker, which saves a lot of time. I am very satisfied that they can Play subjective initiative.

The same is true for the subsequent acid cooking process. The thin wood chips and diluted slime acid are no longer boiled directly in a clay pot, but the pot is covered and placed in a pressure cooker to heat over water. The time has changed from the original three Hours shrunk to one hour.

At the stage of rinsing the wood chip acid, Koehler said with apology: "It stands to reason that some of the used acid can be reused, but we haven't found a way yet."

Frederick said calmly: "It's okay, you can study it slowly."

"Wastewater and waste residues must be treated properly. The amount is still small and cannot be seen. When the scale becomes larger in the future, the entire river may not be needed."

In his previous life, he had seen the harm caused by industrial pollution in the 90s and [-]s. It is no joke that a small factory killed animals and plants in a river.

Keller nodded immediately.

In the refining stage, several stone mills have already used magic reciprocating machines as power, and the efficiency is much higher than water power.

Frederick saw a few young students recording various data in the place where additives were added to the pulp, so he went to have a look.

"We document every process, every recipe, and the outcome, and we're ready to find the best of the best," Koehler explained.

"Last time we found that the printed paper was still very rough. After discussion, we felt that there were still gaps in the wood fibers, so we decided to add some finer grass fibers to fill it, and it had a good effect."

Frederick said very satisfied: "Very good, very good, this is very good."

"Different places need different paper, and mastering the rules can meet different needs."

Next to the papermaking trough, several workers skillfully use the net to pick up the pulp.

Kohler showed Frederick a copying net, and said distressedly: "Now we use a net made of copper wire, which will leave marks on the paper."

Frederick smiled and said to him: "It's impossible, but it's okay, just adjust the distance between the marks and take it as your own line."

Koehler shrugged and said, "That's the only way I can think of it."

Frederick took the paper frame and studied it, thinking about it and said: "I think we can weave a pattern on it with thin copper wire, and leave a mark on the finished paper, so that customers know which paper is our product. gone."

Koehler was stunned for a moment, and after thinking about it, he asked, "What pattern do you plan to use?"

Frederick frowned and thought about it. These days, the trademarks often use animals and plants to represent them. Now many animals and plants are used. How about durian?

The problem is that only Psyche and Mrs. Sophie have seen this thing. Mrs. Sophie's logbook was empty for a few days, and she later said that it was because some sailors got a few "huge giants" when they went ashore to find fresh water. A devil fruit covered in thorns" returned to the boat.

He finally chose a traditional pattern, drew a "" in the air with magic elements, and then said: "Use the sketch of the castle to draw the pattern, and add a quill pen in the middle."

Keehler thought it was okay, so he wrote it down.

The paper taken from the copying net is squeezed out of some water first, and then dehydrated in the first roller dehydrator. This dehydrator has a smooth conveyor belt made of slime glue, which conveys the paper to two sides. Press out a lot of water between the first smooth hard rubber rollers, and then put it on the next dehydrator to press out the water with smooth steel rollers and make it smoother.

"This machine was also made by Schmidt." Koehler said, "It is said that it was modified from the machine already in the blacksmith's shop."

Frederick nodded and said, "That's right, these two steel rolling mills were originally supposed to make steel plates, but they have been replaced with less powerful power sources, so it's not bad to use them here."

The rolling mill from the blacksmith shop was brought in, because there was a manual rolling mill used by jewelry craftsmen to roll gold and silver lead sheets as a reference. Everyone just enlarged and strengthened the parts, and finally succeeded after going through some detours.

The two dehydrators in front of me are actually made of recycled waste products. Their shelves and screws are not strong enough in front of steel, but they are easy to deal with paper.

Frederick suddenly thought that the rollers used in the wood peeling rotary cutter just now should also be the product of detours.

At that time, it was not easy to cast and forge such a long steel roller at one time, and the surface would be uneven. Someone proposed to assemble it in sections, but it failed later.

Frederick looked around, and then he and Koehler came to Katie's office.

It's like a laboratory, with shelves lined with colorful bottles and jars.

"Back from playing?" Katie was mixing the ink, "Are you hungry?"

The corners of Frederick's mouth curled up, and he found that a rosy blush had been smeared on her cheeks at some point.

"It's too messy here," Frederick said quickly, "I'm going to Koehler's office."

After speaking, he gave Koehler a wink, and then pulled Tarot, who had been quietly following behind, to run away.

When Katie appeared in front of Frederick again, her face was clean, and she pinched Frederick's face angrily, and Frederick immediately felt that her fingers were greasy.

Taro at the side immediately took out a handkerchief and helped Frederick wipe off the ink on his face. He didn't wipe it off all at once and rubbed it hard several times until his face turned red before he wiped it off.

Seeing this, Koehler suppressed a smile and turned his head away from the legendary genius principal.

Frederick pouted, and pulled Katie to the printing place.
