Take the mall to Datang

"Teacher, Dejian and I will definitely be able to make this steam fan." Li Dejian said.

"Okay, teacher believes that you can do it." Yuan Shan said.

Yuan Shan is well aware of the difficulty of this fan. It can be said that this fan is already the same as a large windmill. It is for cooling the blacksmith workshop rather than blowing air for individuals. Without the support of theoretical knowledge, he really hoped that the two brothers could make a large fan.

I thought in my heart whether I should provide them with some high-grade physics textbooks and other series of textbooks for them to study in depth, but the courses inside still have to be screened, otherwise the plane will be too shocking, and then they will be let If you can't accept it, it will be even more troublesome.

Yuan Shan secretly planned in his heart.

Chapter 337 Saltpeter Ice Making

Yuan Shan instilled a meal of "delicious chicken soup" for the Li family brothers in the blacksmith workshop. The steam engine fan is also something he came up with boldly, but the current temperature also needs to be solved.

Soon he thought of a good way to cool down quickly, and immediately said: "Tiejiang Lu, take someone to the warehouse to bring the saltpeter, and bring some buckets of water."

Blacksmith Lu didn't know what Yuan Shan was going to do, so he took someone to the warehouse to fetch the saltpeter without saying a word. These things were bought from the system voyage when Yuan Shan was researching gunpowder. These things also exist in this era. , and nothing surprising.

"Today I will show you how to turn water into ice. Watch it." Yuanshan said, put the saltpeter in the bucket and start stirring. Cool down to freezing, and this thing can be reused after drying. It is a very good choice for making ice in summer.

Water buckets began to be moved here non-stop. Yuan Shan began to ask people to help stir according to the amount of saltpeter before, and soon there were more than a dozen large ice cubes placed in the blacksmith workshop, and the temperature dropped a little in an instant. Suddenly there are so many ice cubes in the workshop environment, the feeling of cooling is very obvious.

"Master is really a genius. It's really cool to be able to make water into ice." A craftsman said excitedly, wanting to eat those ice cubes while talking.

"What are you going to do? Put down those ice cubes. This kind of disappearing disease is inedible. If you want to drink it cold, you should quickly get a kettle and put it on the ice to drink it. Do not eat it directly. It will be poisonous." Yuan Shan immediately shouted loudly.

"Click!" The ice cube slipped from the craftsman's hand in an instant, and he wasn't the only one who wanted to eat one ice cube or two in the hot workshop. After hearing that it might be poisonous, these people were all frightened.

"It's just that you can't drink it directly. As for scaring you like this, why don't you quickly gather the ice cubes on the ground together." Yuan Shan said.

The people brought by Craftsman Yang quickly took the cool white leaves and put them on the ice to start chilling. The ice cubes gathered together melted very slowly, and the continuous cool air made people feel very comfortable.

It’s just that the temperature of the steam engine and the glass sintering furnace is still very hot. Yuan Shan took a look at the limited scope of the cooling effect of the ice cubes. At present, it still cannot satisfy the cooling of such a large space, but this has already achieved some effects. It is considered a good one. Start.

I said that after I have a fan, I can use these ice cubes to blow out a much larger range of cold air, which can help more people cool down. At that time, I can also make some hit ventilation to send cold air into the pipe, so that the cold air The uniform overall cooling effect will be better.

The workers in the workshop continued to be busy. Yuan Shan approached the two brothers of the Li family and told them his thoughts. This was the first time they had heard of this method of conveying cold air, and they were quite surprised. .

If someone else said it, they might all believe it. Li Dejian said: "Teacher, we will work hard to study fans, and we will definitely be able to develop a device that will make Datang crazy about it."

"Well, before that, you should go to the manor and transport some of the saltpetre in the warehouse by horse-drawn cart. According to the current consumption, a large amount of ice is needed to cool down the temperature of the blacksmith workshop. In addition, it is called Caiyi. Bring some mung beans." Yuan Shan ordered.

Li Dejian went to Yuan's house soon, riding a bicycle back and forth at a fast speed, the result was that the saltpeter was transported in a horse-drawn cart, and then more ice cubes were made. After a lot of work, the temperature of the blacksmith's workshop began to rise A large area fell.

"This amount of saltpeter is not enough, we need more." Yuan Shan said heartily, after a while, Caiyi and a few maids brought mung beans and started to set up a big pot outside the workshop to cook mung beans.

This is mung bean water, which has the effect of relieving heat, and the ice cubes in the workshop will taste better when it is chilled on it. Caiyi leads people to work outside, and it is too hot for them on a hot day.

After the mung bean water was boiled, it was an hour later, and the people in the workshop were asked to drink iced mung bean water in the afternoon.

"Wow, it's really delicious." Li Dejian said.

"Of course it's delicious, but rock sugar is added to it." Yuan Shan said.

I stayed in the workshop until the sun went down and didn’t leave. The workshop didn’t need to work overtime at night. After a busy day, the workers began to go back to the staff dormitory. What they need now is to take a cold bath in the public bathhouse of the dormitory Then rest well at night.

This kind of life has already formed a pattern, and if some people like a few cups of Xiaoyi, they can go to the staff cafeteria, where they can provide them with drinks and food.

Yuan Shan had a lot of feelings this afternoon, because it was very difficult for the workers to work hard in such an environment as a workshop, and if it was Yuan Shan who worked in that environment, he would definitely not be able to persist.

"Husband, why are you still in the study, it's time for dinner." Dugu Ruolan came to the study and said.

"Oh, I see. I just came back from the workshop and found that there are still many things to do. I forgot the time." Yuan Shan said.

"Husband, don't worry too much." Dugu Ruolan said.

"En." Yuan Shan replied.

But what Dugu Ruolan was thinking about behind her was the workshop refrigeration plan, such as freon refrigeration, compressors, condensers and other things.

It's unrealistic to think about it, but he still needs to check the price of the refrigeration equipment if he has the system prepared. If Dugu Ruolan hadn't come to the study just now, he might have already done the check.

During the meal, Dugu Ruolan said: "Husband, the weather is getting hotter and hotter, I thought how about using cold and iced mung bean soup to provide the workshop staff with some refreshing drinks."

"It's very good. It's very convenient to freeze them together and send them to the workshop with a quilt to keep warm. Caiyi told you about the workshop today." Yuan Shan said.

"Well, I also want to share some for my husband." Dugu Ruolan said.

"It's really hard for Ruolan." Yuan Shan said.

"Husband, how can I help you." Du Qianyu asked from the side.

In an instant, Yuan Shan's face turned dark. Du Qianyu didn't have much talent in being a cook, so he didn't want to poison the employees with dark cooking.

"Qian Yu, the injury on your hand hasn't healed yet, you still need to cultivate well during this time." Yuan Shan said.

Dugu Ruolan also said: "Sister Qianyu, it's better to listen to your husband and take a good rest. These things can be done by the maids in the manor."

Their opinions on the matter of not letting Du Qianyu get involved in a series of things such as cooking were surprisingly unanimous.

Li Xiuning on the side saw what they meant very clearly. As far as Du Qianyu's culinary skills can cook things, it is already good. As for whether he can eat or not, that is not a matter of consideration. Daughter, everyone is a lady, how can she cook food, and later she became a female soldier who guards the princess, so she doesn't need to think about these issues, so it is understandable that her cooking skills are not very good.

Chapter 338 Popsicle Mold

The next day, Yuan Shan took the lead in making mung bean water at home, and then put the mung bean water into the cold storage to freeze it, and then served it to the female workers and workshop workers.

It is very simple to make mung bean water. It is boiled and then chilled. When making this, Yuanshan suddenly thought why not make popsicles directly. Isn’t it ok to add ice cubes and sugar to the popsicle chopsticks and freeze it, and add some food flavors, etc. It will add many different colors to the popsicles.

Now there are some ice creams made of dairy products in the cold storage of Yuanjia, which are relatively high-end cold drinks for this era. Yuan Shan really thought about popsicles at first, but later things got more and more and he forgot After.

Thinking about it, he went to his private attic alone, opened the system mall and started looking for popsicle grinding tools, and saw that the stainless steel fifty-piece molds were priced at [-] guan, Yuan Shanxin said that this system mall is simply stealing money.

Then I went to the cold storage and bought ten molds directly, which can freeze [-] popsicles at a time. In the blink of an eye, [-] guan was spent in this way. This money is also a lot of money for ordinary wealthy families. Yuan Shan was also very distressed when he spent it. It is not difficult to spend the money he has earned for such a long time.

Now it seems that it is really not difficult.

After purchasing the stainless steel popsicle molds, Yuan Shan bought some raw materials for processing popsicles. These things are not expensive at all, and they are very easy to process for Shangliang Baikai.

In a blink of an eye, Yuan Shan came to Yuanjia Restaurant again. He is not stupid that popsicle molds are so expensive, so he bought some stainless steel basins. He thought that using these basins to freeze ice cubes would be the same, and he could directly cut ice cubes and make them. shaved ice.

The price of the stainless steel basin is cheaper than the popsicle molds. In the restaurant, he handed over the method of making popsicles to Yunxi, the beautiful cook, and other kitchen helpers. They learned it very carefully.

After some preparation, Yuanshan took the people and the prepared cold drinking water to the cold storage and began to teach them how to make popsicles. Yuanshan bought the first batch of popsicle chopsticks from the system mall.

"Master, is that so? Is it enough to put this wooden stick in?" Yunxi asked.

"That's right, and you have to come over every once in a while to take out all the frozen popsicles, and then make new ones, and ask someone to bring these popsicle chopsticks to Artisan Yang, so that they can make more batches. " Yuan Shan said.

"Understood, young master." Yunxi said.
