After agreeing with Vanilla, let Vanilla teach Lian Zhou and Lian Zhi's mother and daughter to cook, and Li Xin first asked Zhu Yong to send Vanilla to the house in Osmanthus Village. Li Xin stayed on the Zhuangzi by himself, watching the rape and peas harvested.

When the rape and peas were almost harvested, Shopkeeper Sun took two middle-aged men of the same age as him to Li Xin's Zhuangzi.

"Why is Shopkeeper Sun free?" Hearing that Shopkeeper Sun was coming, Li Xin went to greet him in person. Shopkeeper Sun and the Li family gradually got acquainted with each other, Shopkeeper Sun was kind, and on weekdays, he was also very kind and kind to Li Xin's sisters and brothers, but he was very liked by the Li family. For Li Xin's sisters and brothers, Shopkeeper Sun is like a relative.

"Naturally, I knew that Zhuangzi was busy here, so I came to take a look and see if there was anything I could do to help. Wouldn't Miss Li welcome us? Shopkeeper Sun got out of the carriage with a smile.

"Why don't you welcome it, but please don't come! Let's get inside! ”

When I arrived at the flower hall in the small house, someone had already made fragrant tea and brought all kinds of refreshments. Li Xin beckoned Shopkeeper Sun and the people who were traveling with him to sit, and the guy brought by Shopkeeper Sun had already asked Li Xin to order his subordinates to take them down to entertain them.

"Let me introduce, this is the money shopkeeper, and this is the Zheng shopkeeper." Shopkeeper Sun pointed to the two people who were in the same company and introduced them to Li Xin, the shopkeeper was a very fat middle-aged man, he was very fat, his stomach was bulging, and he was smiling, but he looked like a kind Maitreya Buddha. And the shopkeeper Zheng is very lean, looking very thin, but he also looks energetic. "This is the eldest girl of the Li family." Shopkeeper Sun pointed to Li Xin to give money to the shopkeeper and Shopkeeper Zheng introduced.

After talking to each other, they sat down.

Shopkeeper Sun also went straight to the point, directly explaining the intention of coming this time. Although, Li Xin and Mrs. Sun said that rapeseed oil extraction will be successful, but for matters that they never know, everyone will have some hesitation and curiosity. Therefore, before Shopkeeper Sun left the capital, Mrs. Sun had already explained to him. Let him come to Li Xin's Zhuangzi to take a look and see if the oil extraction from brassica seeds will really be successful, and what is the quality of the oil squeezed.

"The brassica sprouts have almost been harvested, and there are a lot of dried brassica seeds. If the three shopkeepers want to see it, then they will transport a batch to the oil mill and squeeze some rapeseed oil out to have a look. Knowing the intention of the three shopkeepers, Li Xin also smiled and invited the three shopkeepers to watch the process of oil extraction.

Li Xin also knew that because of a few fresh vegetables in her hands, Mrs. Sun would become interested in her, so there would be later cooperation. Although the vegetables that came out of Li Xin's hands before were indeed novel, and they were all delicious. But it doesn't mean that Li Xin will succeed every time, Mrs. Sun is a little worried, and it is understandable to let the three shopkeepers come over to watch the extraction of rapeseed oil. Moreover, such caution also makes Li Xin like it very much.

If it weren't for Mrs. Sun's courage and prudence, I am afraid it would be difficult to take charge of so many shops of the Sun family!

"I'm really curious, if Miss Li can let us go over and watch, it will be good." The money shopkeeper said with a smile.

"Since the three shopkeepers are interested, let's go over and have a look!"

After that, Li Xin instructed people to carry some sun-dried rapeseed to the carriage, and then took the carriage and went to the oil mill in Baihua Town. The oil mill has not been traded since Li Xin bought it, but it is very quiet. When I entered the door, the inside was cleaned, and in the room on the other side of the small courtyard at the back, a new set of equipment for oil extraction was remade, which was still brand new and had not been used.

In fact, the equipment used for oil extraction in this era was very simple, and it was not as simple and fast as the machines that Li Xin saw in his later generations. The oil extraction here is completely handmade.

At a glance, the kettle retort, stove, wood press, iron hoop, hammer, oil cylinder and other oil extraction tools are neat and clean, the left side of the press room is the rolling room, after the kang roasted rapeseed is cooled, it is evenly poured into the grinding trough, in the sound of the water wheel, it can be slowly ground into powder.

There are more than a dozen processes in the process of oil extraction, and each link is completed by hand, which does not seem to be difficult, but if you are not careful, you will produce less oil or even no oil.

Fortunately, the guys are all proficient in oil extraction, and Li Xin has the recipe given by Yang Zhu's wife in his hand, so he is not worried that he will not be able to squeeze oil.

Li Xin handed over the rapeseed to the guys in the oil mill, and watched the guys get busy, while she took the three shopkeepers to visit on the side. Zhao Da was also waiting on the side, and explained to Li Xin and a few people from time to time, it seems that after arriving at the oil mill, Zhao Da still did a lot of work! At least, the steps of this oil extraction are almost understood, whether it is professional or not, in the end, it is the head of the way, but it has to make people look at it differently.

It seems that it is not unreasonable for the Zhao family to be able to thrive in the Lian family back then, and it is not just because Zhao Da is the companion of the Lian Zhou family.

"It seems that this oil extraction is really interesting! I haven't known about it before. Watching the guys squeeze oil, Shopkeeper Sun also sighed.

The rapeseed is fried before it is pressed, and there is a burnt smell that fills the room. Li Xin also likes this taste very much, it is a very natural aroma. The growth of plants has absorbed a lot of the essence of heaven and earth, with a natural sense of freshness.

"Yes! Don't look at it as a mere oil, but it's really not simple! Shopkeeper Zheng also sighed.

"Miss Li, when will I be able to eat this oil?" The money shopkeeper looked at the rapeseed oil flowing out with a curious expression.

"Not for the time being, I have to let it sit for a few days, and then I can eat it when the oil is gradually clean." Li Xin explained. In the previous life, there were centrifuges for oil extraction, which could accelerate the purification of rapeseed oil, but there was no centrifuge here, and the freshly squeezed rapeseed oil should be left to stand for many days, and the impurities gradually precipitated to form "oil turbidity", and then skimmed off the foam on it with a spoon and poured out the clean oil. Rapeseed oil that has not been purified by centrifugation will form a thick layer of "oil turbidity" and sink at the bottom of the bottle during use.

"Miss Li is saying that this oil can't be eaten for the time being?" Shopkeeper Sun also looked at Li Xin.

"Yes! Good oil doesn't take time, and the three shopkeepers won't be in such a hurry! When the oil is ready, I will definitely send someone to Pinxiang Pavilion as soon as possible. Li Xin replied with a smile. The freshly squeezed rapeseed oil still has a lot of impurities in it, and Li Xin doesn't dare to let people eat it at this time.

"Miss Li is right, it still takes time for good oil to be good. Then we'll wait for Miss Li's oil. Shopkeeper Zheng looked at Li Xin with some deep meaning
