Zhu Biao chose to stay for one more day and go to Mengcheng County tomorrow.
He decided to help as many people as possible along the way, as he could not come back during the Chinese New Year anyway.
Longkangji was originally a county, which lasted until the Song Dynasty. After the war, the Yuan Dynasty ruled and the county was removed.
As long as the Ming Dynasty continued to develop its navy and encourage inland shipping, this place would inevitably develop again.
The team stopped, and the people selling vegetables nearby were the first to be popular. The prince's team sent people and cars to pick vegetables in their fields.
Weigh immediately after picking, and pay once for picking.
Jiayuan watched helplessly, Zhu Ping went over and told them that they would also send a car to their house to pick up food. They quickly packed their things and took people on the road.
Zhu Biao stood by the river and looked at the opposite bank: "Would it be better to build a bridge?"
The captain accompanying him took a look with a telescope: "The height of the bridge opening should be high to facilitate the passage of ships."
Zhu Wentian was watching from the other side. He knew what it looked like to build bridges at this location. There were several.
However, the river is much narrower than it is now, and the flow volume has become smaller. Shipping has basically disappeared, leaving only economically operating ships.
At this time, people with good water quality go down to the river to touch the clams, while people with poor water quality go to other small rivers to touch them.
The people in the team are used to walking all the way looking for food, especially the craftsmen.
At first, they thought that if they followed the team, they would have access to roads and supplies, and it would be very fast.
It turned out that something was wrong. Starting from the second day, the team stopped and went, hunting game and netting fish.
Nowadays, the fishing nets are constantly busy, and idle people are touching river mussels. River mussels larger than a palm can be seen everywhere.
The children who came to get snacks also helped. When the people saw His Highness the Crown Prince's team touching river clams, they went to their homes to fetch chickens and ducks to give to the Crown Prince and King Qin.
"Your Highness, river mussels are not delicious. The bigger they are, the harder they are to chew. They cannot be chewed at all, just like chewing branches, unless they are cooked with a lot of firewood."
Zhang Luming, the village chief here, came over with a rooster in his hand and advised Zhu Biao not to eat river mussels.
Zhu Biao recalled it and said to Zhang Luming: "The river mussels I ate were not difficult to chew, Zhu Lichang?"
"I asked His Highness the Prince, it was because the beating method taught to Guanglu Temple by Xiaqiu Village broke up the mussel meat.
Ordinary people don't know, they just throw it into a pot or jar and cook it, add a little salt, and use it as a food to satisfy their hunger.
Or if the meat is cooked for a long time, the meat will be cooked to pieces, which is really a waste of firewood and the people are not willing to eat it. "
The manager knows the reason and the method of operation. He spoke more respectfully than usual, in the presence of an outsider.
"Zhang Lichang, you can ask the people to watch the production method and try it at home." Zhu Biao nodded.
As for the poultry sent by the people, they don't want it. They take it back to lay eggs or eat it themselves.
"In fact, we can make some utensils and place them where there are mussels. We can cook mussels for the people and charge according to the weight of mussel meat. Your Highness, please come with me."
The head of the village decided to come up with another good thing. On this trip, Xiaqiu Village brought all the technologies it could.
Zhu Biao and Zhu Feng followed curiously and came to their own small camp in Xiaqiu Village.
Seeing that no one was stopping him, Zhang Luming followed him here.
The chief looked at the car numbers, selected car No. 4, and took out a pot with a lid.
"Your Highnesses, please see, this pot is called a pressure cooker, and a pressure test gauge is used when testing it after manufacturing.
Nowadays, there is only a simple pressure relief valve. When the pressure in the pot reaches a certain level, it will pop up and emit gas to prevent the pot from exploding.
Since you need to make a steam engine, you must know the pressure. At the same time, it is easy to use the principles of the steam engine to make a pressure cooker.
The village made a pressure gauge, tested it with water pressure, and used the depth of the water instead of the air pressure to get the data from the pressure gauge.
water vapor……"
The manager talked a lot, introducing the principles of pressure cookers and the relationship between air pressure and water boiling.
Zhu Biao and Zhu Fang are trying to remember. They always deal with children in Xiaqiu Village, have learned some knowledge, and can now keep up.
Zhang Luming, the chief next to him, felt his head buzzing. He could guarantee that he knew every word of what the other chief said, just put them together...
"Mr. Li, is this how a lot of the cooked food in the deli is made?"
Zhu Xi remembered that the delicatessen was selling out cooked food very quickly, especially pork head meat and pig trotters.
The meat cooked in the store is soft and delicious when eaten, and it takes only a short time.
Zhang Luming didn't say anything, knowing that the commander His Highness King Qin was talking about was not him.
"Your Highness is right. That is a high-pressure barrel and can do a lot at one time." The chief nodded.
"It's long, it's not affected by the weather outside?" Zhu Biao asked.
"Exactly!" The director continued to nod.
"In this case, it can be used to cook food in the northwest. I heard that the rice cooked there is not cooked and can only be stir-fried and fried."
Zhu Biao thought of the role of the pressure cooker in front of him. Going to the northwest, where the place is high, the air pressure is low according to what the director said, and the boiling temperature of water is low.
So before the food is cooked, the water boils and the temperature cannot rise.
"That's right." The director still nodded.
"Make a pot and see." Zhu Biao was ready to see it with his own eyes. At the same time, he also prepared a pot next to him to compare the two pots.
"How about chicken stew?" Li Chang asked, taking a look at the rooster on Zhang Luming's hand.
"Yes!" Zhu Biao also looked over.
Zhang Luming presented the chicken, and the children quickly slaughtered it, collected the blood, removed the chicken feathers, and then cut the chicken into two parts.
However, the chicken head, which is the most difficult to cook, is placed in the pressure cooker. Add aniseed, ginger slices, and green onions, and put the two pots on the stove at the same time.
"If the cooking time is much shorter, we can save firewood. Can you look at the cost of firewood and the fees charged?"
Zhu Biao stood next to the two pots and said what the director had mentioned before.
Put the pressure cooker at the market and process mussels for others, one pot at a time. How much is the appropriate charge?
"Actually, it's better to use a big bucket. We have it on the car, but we can't leave it to the people. It's for our emergency use.
If you think it is feasible and deliver it to the people later, His Highness can write back and ask the village to provide technical and safety testing.
The pressure test must be passed. Otherwise, if the air leaks, it will injure and kill people. "
The chief first made it clear that the items in the car could not be given away. The reason why they are not being used now is that they cannot be used.
Stewed chicken still tastes better when simmered slowly in a normal pot, especially braised pork.
Zhu Xi came to the pressure cooker, stretched out his fingers and slowly moved towards the lid, then immediately retracted his hand after touching it.
"Hot, steel? How was this made?"
"For forging, we use molds and steel pillars. After raising them, we lower them for forging. If we cast them, we worry about trachoma."
"I can't think of anything. When the time comes, let them go to the village to learn, and teach them the low-skilled ones. The valve on top is the most important, right? No need to teach."
Zhu Ping couldn't look at the entire manufacturing process now, so he simply didn't think about it, otherwise he would feel tired.
Today's third update is late. I don't know which family's dog downstairs keeps barking, alas!
