Seeing the last batch of takeaways delivered out, Qin Shen also really breathed a sigh of relief, "I really didn't expect the takeaway business to be so good on the first day." ”

"Yes! I guess there are a lot of people who are curious about takeout! Qiao Su broke a bowl of mung bean water and gave it to Qin Shen, "The weather is getting hotter and hotter, and this is too busy and it will make people easy to get angry, I asked the kitchen to cook mung bean water, in addition to the diners, the guys in the restaurant can also drink it." After speaking, she also approached Qin Shen and whispered, "Don't worry, you added sugar to you." ”

Qin Shen smiled at Qiao Su, took the mung bean soup and drank it. "It's hot, are we going to start making ice?"

Qiao Su was stunned, if this matter hadn't been talked about by Qin Shen, she would ...... Forget it! "You're right, it's necessary to prepare in advance, after all, we have already prepared the cellar or something, and after getting ice this time, we can also make some ice bowls and sell them in the restaurant."

"Is there any way to make the ice bowl available as a takeaway?" Qin Shen thinks that if there is an ice bowl in the takeaway, then the business should be better, right?

"If you want to send an ice bowl, you need to keep the temperature ......, there was no foam board in ancient times, and there was no freezer......

Qin Shen thought for a while, and suddenly said, "We can get a box specifically to store ice bowls, this box can be made of bamboo, and make a sandwich." ”

"You want to put ice in the mezzanine?" Qiao Su immediately understood what Qin Shen meant, and she smiled, "That's a really good idea!" If you make such a box, you can put an ice bowl inside, and then a quilt on the outside. ”

"Quilted?" Qin Shen looked at Qiao Su suspiciously, and gave the ice bowl ...... Cover the quilt?

Qiao Su scratched her head, thinking about how to explain it to Qin Shen, she organized her words and said: "When we are cold, we use quilts to keep warm, because our bodies will heat up, but ice is different, if you don't consider the temperature, ice will always be cold." The function of the quilt is to maintain the temperature, and after the quilt is covered with the quilt, it will block the sunlight and the high temperature outside, and keep the ice cold...... Probably...... That's what it means. "In fact, the quilt can reduce the heat transfer between the ice and the outside world, and there are three ways of heat transfer, even conduction, convection and radiation, but if she says this, it is estimated that Qin Shen will not understand! Of course, there is another key problem, that is, no matter how detailed she is, she can't explain it, after all, she is not from a science and engineering background!

"Is that so? Shall we go back and try it while we make ice? Qin Shen didn't veto Qiao Su's statement, he just felt that this matter was very ...... It's interesting, so I'm going to go back and try it out and see if there's any difference between the ice with and without the quilt.

"Good! Be sure to ask the kids to observe with you. Qiao Su thinks that practice is very important, Qin Shen needs to be encouraged to have such a method that he wants to try himself, at least let the children learn to see things in this way.

Wang Baiyu had already dealt with all the things in the kitchen at this time, she sat on the side and knocked her arm and leg, "I don't know when those people will come?" ”

Liu raised his hand and poked Wang Baiyu's forehead, "You're too anxious, aren't you?" It's not dinner yet, huh? There's news here, at least until everyone has dinner, and then they will sort out what they see and hear, and then someone will send it to you! ”

"Okay!" Wang Baiyu had to admit that Liu's words were right, and she actually understood, after all, this plan was decided after they discussed it together! But she's in a hurry!

"I don't think you're busy enough." Josu walked over and said with a smile, "Let's go, go out shopping with me." ”

As soon as he heard that he was going out, Wang Baiyu suddenly jumped up, "What are you going to buy?" ”

"Secret!" It's already past dinner at this time, even if someone orders takeout, the people in the restaurant deserve it, and it's not a big problem for Qiao Su to go out for a while.

"Here is me and Mr. Qin, you can go out with confidence!" Liu knew very well that Qiao Su was not the kind of person who would run around, so she didn't tell anything, thinking that before the restaurant was busy at night, Qiao Su would definitely come back with Wang Baiyu.

The two went out to call a carriage, and in the car, Qiao Su told Wang Baiyu that the purpose of going out this time was to buy saltpeter.

Wang Baiyu thought about it, and asked Qiao Su very business-mindedly if she could tell her father about this method, so that in addition to buying wood and wood products in the summer, the Wang family wood method could also sell ice.

"Absolutely! This method is not worth anything, you can just tell Brother Wang directly, but ...... After you reminded them, I thought of telling Uncle Chen about this method of ice making, so that they could have an income before the livestock and fields in the mountains were harvested. Josu said with a smile. She really hadn't thought about this ice-making business, after all, the restaurant was enough for them to be busy, but as soon as Wang Baiyu said this, she was also moved.

"What's this! Our Wangjia Wood Mill is not only doing business in Shunzhou, if Master tells my father this method, he will definitely let all the wood mills do this business! And Uncle Chen, even if they sell ice, how much can they sell? After all, they have limited manpower, and that's okay! Wang Baiyu said.

After the two went out, they bought a lot of saltpeter, and then asked the coachman to help deliver the saltpeter to the house, Li Lin saw it, and immediately came out to help, he and the coachman quickly sent the saltpeter to the shadow wall, and then it was Li Lin's business alone.

Qiao Su gave the coachman the money for the car, and took Wang Baiyu into the house, "It just so happened that you came over, directly bring back some of the wine I brewed, and then you can send it directly to your cousin in the wooden workshop, so that at night, can't you take the wine home directly?" ”

"Hmmm! Thank You, Master! Since it was Master's own wine, it must be better than the one you bought from the sake brewery! When the time comes, I will ask my mother to see if there is no need to order wine from the winery when the nest is married. Wang Baiyu adhered to the idea that fertilizer and water would not fall into the fields of outsiders.

"Don't be in a hurry! I don't make a lot of this wine, even if I sell it in a restaurant, I have to limit it. When you get married, you want to hold a running water banquet, and it is estimated that you will use a lot of wine at that time, and I may not have enough here! "She gave Wang Baiyu wine, but because of the newly brewed good things, she wanted to taste it for the people around her first, not to mention that she was very confident in the wine, which was not sold in the restaurant! Naturally, there is no need to ask Wang Baiyu to help sell wine through the wedding banquet.
