The product that Luo Yuhong wants to try out is plant essential oil.

Many men don't know about essential oils, but women are familiar with them. What is the effect, wipe your face, your face is not tight, and it is fragrant, much better than the earthy stuff like sachet incense powder. So, a woman who has never used plant essential oils can't be regarded as a woman with status and taste, it's just ...... It's not a woman!

The trial production of plant essential oils can bring the relationship with the princess closer and lay a material foundation for opening the door to make money. More importantly, through the trial production of plant essential oils, we can master the most advanced chemical production technology in this era, and we can cultivate a group of cadres who understand science and technology, and accumulate experience for the next step of gunpowder and triacid and alkali.

This is the market route and technical route that Luo Yuhong finally chose after thinking about it for several nights.

Luo Yuhong stood next to him with his hands on his waist, personally supervising the eunuch leader and shouting at a group of small eunuchs to move bricks up and down.

First, build a simple circular stove with fire bricks, leaving a gap for firewood. Then put the cauldron and then the steamer. Add water to the pot, add firewood to the stove, then light the fire and start steaming the steamed buns...... None of the above are the core technologies, the core technologies are as follows:

This steamer is a little different from the steamer for steaming steamed buns. A small hole is drilled into the side of each steamer. At the entrance of the cave, a thin bamboo pipe is inserted diagonally in different directions.

Yes, this is what was converted from a steamer from a steamed bun shop. It was Zhu Pingjin who responded to Luo Yuhong's strong request, and used his identity as the son of the family to forcibly buy it from a craftsman's family. For this reason, Shizifu also accompanied the ordered bun shop with some silver, and by the way, bought the matching big iron pot of the bun shop.

"Take out the two sacks of dried flowers and sprinkle them evenly in each drawer of steamers." Luo Yuhong commanded.

Yes, this is dried flowers. In winter there are only dried flowers, no flowers. These two bags of dried flowers were also put forward by Zhu Pingjin from the treasury of the palace at Luo Yuhong's strong request. The reason why Zhu Pingjin picked up the goods was that as a man with status, taste and temperament, he liked to sprinkle some in the bathtub. However, although Zhu Pingjin's reason is peculiar, it is not excessive. The wealthy families of Chengdu Mansion often store some dried flowers, incense pieces and other similar things at home to fill incense sachets.

"Cover the steamer tightly, and put a few more fire bricks on the lid of the steamer to compact!" Luo Yuhong commanded again.

The fire in the stove grew bigger and bigger, and black smoke pulled the flames and bubbled out along the edge of the pot.

After the experience of Qingyang Palace, Li Sixian's fire-burning skills have been perfected. Seeing the smoke coming out of the stove, he hurriedly loosened the firewood with tongs, and handed the firewood from the stove into the stove to prevent them from blocking the door. There was fresh air in the hearth, and I suddenly felt relieved, and the black smoke immediately decreased. After a while, the water in the cauldron was boiling open, and steam came out of the thin bamboo pipe next to the steamer.

"Hey, who's that, come here!" Luo Yuhong beckoned to Li Sixian, who was burning the fire, "You are very good at burning fires." What is your name? ”

Li Sixian hurriedly handed the tongs to the next family and ran over, forgetting to wipe the black smoke on his face.

"Slave Li Sixian. It turned out that the prince was waiting by his side, but now the prince has specially sent slaves and maids to wait for you. ”

"Oh, I see! He has a conscience! Luo Yuhong nodded and said, "No wonder you look a little familiar." ”

"The night before that, the prince invited you, and he sent a slave and maid. Later, you were sent back to the house in a sedan chair, and it was also a slave. Li Sixian hurriedly pointed to his face and reminded.

"Oh, I said yes, no wonder I look at you so familiarly!" Once misunderstood people, Luo Yuhong looked at the little eunuch's face, and then looked at his nails, a little embarrassed. If it weren't for this little eunuch insisting on taking her to the Shizi Mansion, maybe Zhu Pingjin would have found another woman to marry.

"You're capable!" Luo Yuhong found an old acquaintance, and the psychological distance was much closer, "You have to take care of these people well, and don't allow them to be lazy!" As he spoke, Luo Yuhong bent down and picked up a newly bought night pot from the ground, handed it to Li Sixian, and then untied the big red girdle with his hand, and ordered: "Take one under each bamboo pipe, and pour it into the bucket when it is full." Don't be short of people here, you arrange people to take turns on duty! I'm going to steam it for seven hundred and forty-nine hours! Remember, don't boil the water dry, don't let the steam leak, it's all money! ”

The fire in the stove burned all night.

The next morning, Luo Yuhong slept comfortably. It was shining, and then I remembered that it was time to go to work. She hurriedly changed into work clothes and went to the front yard to check the production of products.

Li Sixian didn't sleep all night last night. Miss Luo praised him for reusing him at the beginning, making him feel that he had a great responsibility, and he was afraid that the little eunuchs would be lazy and boil the water dry, and live up to the trust of the prince and Miss Luo. Therefore, the other little eunuchs changed shifts twice, and he himself sat by the stove and insisted. Seeing Luo Yuhong appear at the second gate with a radiant face, Li Sixian hurriedly ran over to report how much steam water he received last night.

"It's the first time I've seen such a dedicated employee without taking a penny, I want to talk to Zhu Pingjin about it, and cultivate it!" Luo Yuhong looked at Li Sixian's flowery face and red eyes with feeling, turned around and instructed Xiaohong, "You go and fetch him a basin of water and let him wipe his face!" ”

Little Red muttered.

Li Sixian's eyes flashed with tears of excitement.

The steam condensate in the tub has been picked up a lot.

Luo Yuhong picked up a water scoop, scooped some water from the water, and then walked outside the house to look at the sun. There is a thick layer of oil flowers floating on the water, which is colorful in the sun. Luo Yuhong put her nose up, and a floral fragrance overflowed from the water.

"We succeeded, we won the first battle!" Luo Yuhong happily shouted at the courtyard three times, and even Li Sixian, whose head was stuffed in the washing water, heard it.

Luo Yuhong chose the technical route of essential oil extraction, using the most primitive steam distillation method. This method is so simple that any fool who has eaten steamed steamed buns will do it. Of course, the method of boiling is simpler, but some plants and flowers will lose their flavor after boiling them in water for a long time. Luo Yuhong didn't want to spend time separating the petals in the dried flowers, and she didn't know that those petals couldn't be boiled for a long time, so she went directly to the steam distillation method.

After the plant essential oil, the next step is to separate the oil and water more simply, that is, scoop up the oil flowers floating on the water surface and put them in a porcelain bottle alone. Zhu Pingjin has already arranged for a porcelain vase to be placed at a porcelain shop in the city, and it will take a few days to deliver it. It is not that these porcelains are difficult to fire, but that the porcelain kiln must customize the mold of the porcelain tire in order to meet the custom requirements of the uniform size of the porcelain vase.

Luo Yuhong put the water scoop back into the bath bucket, circled around the stove a few times, and muttered to herself: "In the next step, you can also improve the process in several aspects: the opening of the bath bucket is too large, so the oil surface is very thin, so it is difficult to scoop up the oil alone, and it is easy to mix the water." So make something with a small opening, such as a thick bamboo tube. It is too wasteful to use people to scoop oil, it is best to drill a hole above the thick bamboo tube, insert a thin bamboo pipe, and the oil-water mixture reaches the height of the hole, and the oil will automatically overflow and be separated from the water; Drill a hole at the bottom of the thick bamboo tube, plug it with a wooden plug, the water level is too high, pull out the wooden plug and release the water, so as not to let the water level be too high and the oil and water come out together. Each drawer of the steamer leads a bamboo pipe to simply take off the pants and fart, just keep the top thin bamboo pipe, and the rest can be blocked, but the steam pressure in the steamer will not be too great......"

Luo Yuhong searched for what she had learned in school in the past while working hard to improve her product production process. Little did she realize that the plant essential oil production line, which had been perfected by her brain, was becoming more and more like the towering distillation separation tower of a modern oil refinery. The main difference in appearance, one is a bamboo tube, and the other is an iron tower.

"That Li Sixian!" Luo Yuhong called him over after washing his face and handed him a night pot, "You arrange for someone to scoop up the essential oil in the bucket and put it into this pot." Be careful not to mix the water and only scoop the oil off the surface! You say, what if the oil is mixed with water? ”

Li Sixian wiped a handful of water from his face, and thought about it: "The slave and maid will pour the scooped oil and water into another pot and scoop it again." Anyway, the oil is light and the water is heavy, and the oil is always on the top and the water is down. The slave and maid scoop it several times, and the oil and water will always be clean! ”

Luo Yuhong patted Li Sixian on the shoulder and praised him: "Yes! You're smart and capable. Do it well, I'll tell Shizi! ”

Li Sixian's tears really came out.

After arranging things, Luo Yuhong returned to her office. Now that the product has been successfully rolled off the production line, the next step is to bring the product to market. She hasn't fully figured out the sales strategy of the market, such as whether to introduce MLM techniques? Do you want to go to print media? Do you want to do a reality show catwalk at a product promotion meeting? How to set up a distribution network for products? How to launch new products with the help of existing sales networks, etc. However, she soon decided that the sales platform of essential oils had to be placed in her own house, that is, at her family's Fu Ren Tang Pharmacy. If it is not good to be a medicine, it will be sold as a health care product, and a separate health care product counter can be built.

"When a man has too much money, he goes bad. It's not a good thing that he has too much money in his pocket, and maybe something will happen! Luo Yuhong thought, "I don't know when I'll see my mother?" If he hadn't insisted, I would have just gone to bed and put him ...... See what he can do! He still dares to resist? It's not like he doesn't even recognize his wife! ”

Luo Yuhong thought of personal matters, and her heart was bored for a while, so she had to try to put aside her distracting thoughts and force her thoughts to return to work. Now that you have essential oils, you can consider the next derivative product, such as ...... Luo Yuhong silently filtered the essential oil products she had seen before in her brain, such as petroleum jelly and alabaster...... This stuff is too complicated......

Pregnant! A scene popped up in Luo Yuhong's brain. The subway station sells handmade essential oil soaps, translucent, fragrant, cute, and all kinds of cartoon shapes. This product is good! It is simple and sell-good, and it goes well with health care products, and it can be sold over the counter. Caustic soda is not easy to find, so it is replaced by soaking water with plant ash. The water soaked in plant ash is a little dirty, and it will be clear after filtering it twice. The ash in the stove can't be discarded at will, that's money.

The person who sells handmade soap in the subway station is a small female college student who likes to sell cuteness, and next to her boyfriend. Her little boyfriend is pretty handsome......

Luo Yuhong looked at the various exquisite bonsai outside the window and thought about it.
