After inspecting the white sugar workshop, Liu Feng took Mina and Allie to inspect other workshops.

First I went to the canning workshop, then I went to the brewery and the instant noodle production workshop, and now I have just finished inspecting the linen workshop.

"Young Master, was the oil extraction you mentioned last time also in this workshop area?" Allie flipped through the memory book and turned her head to ask.

For oil, Allie is extremely curious, there are so many delicacies that can be eaten in the castle, among which it is inseparable from oil.

In this world, the source of oil can only be obtained from wild boars, the quantity is very small, only the nobles can afford oil, and the price of oil is also very expensive, several times more expensive than salt.

The aristocracy used oil to make some dim sum, not to stir-fry, and stir-fry was not invented in this era, and most people used the way of cooking.

The oil Liu Feng said is peanut oil, which is pressed out of peanuts, which is also the oil currently mainly used.

Of course, there is also a plant dried fruit oil, which is a product of this era, but the quantity is relatively small, and it was taken by Liu Feng to make marriage cream...

And like Zuixiaolou and various gourmet stores, peanut oil is now used, but due to the quantity, it is temporarily not sold to the public.

Peanuts have a large number of seeds left when planting greenhouse vegetables, and when they open up the land for farming, they are planted with potatoes.

"Since you're here, let's go and see." Liu Feng said softly.

"Good." An Li answered happily and followed Liu Feng towards the depths of the workshop.

Before coming to the oil pressing workshop, there were eight soldiers on duty at the door, in order to prevent unrelated people from breaking in, after all, oil is such a thing, Liu Feng does not intend to let others know.

In the future, this peanut oil will also be an indispensable thing for the daily life of civilians, which can be said to be a level with salt, after all, firewood, rice, oil, salt, sauce and vinegar tea.

"My lord." Seeing Liu Feng's arrival, the eight soldiers hurriedly saluted.

Liu Feng nodded and led Mina and Allie towards the workshop.

"Boom....."

"Buzz..."

Before entering the door, the sound of the steam engine was already heard, and in the workshop, three presses were working under the drive of the steam engine.

The press is a drawing given by Liu Feng, made by the Ministry of Scientific Research, the shape is a vertical barrel shape, and the power source of pressure is driven by a steam engine.

Pressing peanut oil is to separate the oil directly from the raw material by physical pressure, and the whole process is without any chemical additives.

Before the steam engine appeared, the pressing of peanut oil was pressed by manpower, that is, the most primitive way of pressing peanut oil, and the amount of oil produced was enough for several stores.

Now with the emergence of the steam engine, the amount of peanut oil is more, but now it is also limited by the raw material of peanuts.

"Buzz..."

After Liu Feng and the three entered the workshop, they frowned noisily by the noise, and then looked around carefully.

"Wow, there's a lot of people peeling peanut shells." Allie looked in amazement as a bunch of people peeled peanut shells.

She knows about peanuts, when the first batch of peanuts was harvested, Liu Feng took a little to the castle, so that Nicole fried salty peanut grains, usually nothing can be eaten as a small snack.

"Let's go, go ahead and take a look." Liu Feng walked towards the inside of the workshop.

"Boom..."

The further you go inside, the louder the steam engine becomes.

Liu Feng took Mina and Anlie to refer to the stir-frying process, peanuts are to remove some moisture before pressing, and they must be stir-fried until 6 to 8 years old before pressing oil.

"What a fragrance." The peanut grain in Allie's hand was stuffing it into her mouth.

"It's quite fragrant, but it's not salty." Mina also commented, which is less salty than Nicole's stir-fried peanuts.

Liu Feng rolled his eyes and led the two into the pressing workshop.

The stir-fried peanuts are sent to the press workshop, and then poured into the funnel-shaped inlet, and then pressed, the peanut oil is squeezed out, and then filtered and precipitated, and the production of peanut oil is completed.

"Well, that's how the oil came from." Allie exclaimed, circling the press twice, with little stars in her eyes.

Mina had already met Liu Feng, and she was surprised when she first learned that oil could also be obtained from peanuts.

It's hard to imagine that oil can be obtained from these tiny peanuts, which also makes Mina know that oil can be obtained not only from animals, but also from plants.

"Young master, it's too powerful, the grain grown has such a variety of uses." Allie adored that the sugar cane planted could make sugar, and now peanuts can even squeeze oil.

"Tread, tread..."

Liu Feng smiled and turned his head to look at the person in charge of the workshop who hurried over.

"Lord City Lord." The person in charge of the oil mill, who was in charge of the oil mill, walked over quickly, and he was a member of the veterans.

"Can oil production keep up with consumption now?" Liu Feng asked lightly.

"I can keep up, and there is even a lot of surplus, which has all been stored in the warehouse." The person in charge responded.

"After a while, I will ask the Ministry of Scientific Research to send you another press." Liu Feng said calmly.

"Yes." The person in charge quickly answered.

"Open flames are strictly prohibited in the workshop, so you must pay attention to this." Liu Feng said solemnly.

It's all oil, and if it catches fire, the consequences are unimaginable.

"Yes, we will definitely pay attention." The person in charge respectfully replied, still knowing the seriousness of this and not daring to be careless.

Liu Feng looked around, found no problem, and left with Mina and Allie, after all, the smell in the oil pressing workshop was indeed not very good after a long time.

"Young Master, after staying in it for a while, my whole body feels a little greasy." Allie touched her hair and pouted.

"I was like this last time I came, just go back and take a shower with soap." Mina gently helped remove the debris from Liu Feng's body, she just washed her hair yesterday night, and she has to wash it again when she goes back today.

I don't know why, I used to wash my hair once for a long time, but now even if I wash it every day, I don't think it will be troublesome.

Every time I wash my hair, I feel so refreshed, and my hair is no longer greasy or itchy.

"Young Master, the soap is gone." Allie whispered.

When she bathed with soap for the first time, she found that she could wash so cleanly, and there was a faint fragrance, but now she doesn't use soap, but she is not used to it.

Especially now in summer, after sweating and sticky, it is even more necessary to bathe with soap.

"Gone?" Liu Feng raised his eyebrows, it had indeed been a long time since he brought soap last time.

"Well, some of the soap was given away, and Sheeran, Elsa, and Bliss all gave some soap." Allie explained softly.

"By the way, without soap, how did you bathe before?" Liu Feng asked curiously, he hadn't paid attention to this before.

You must know that Allie was a princess before, could it be that the bath was also spent with clean water?

"With Qingbijiao, it's just that it is not cleaned with soap, and it can't be compared at all." Allie replied.

"Blue Corner? What is this? Liu Feng was stunned, this was the first time he had heard of this thing.

"It is the fruit of a plant, the fingers are so long, like goat's horns." Mina explained softly.

"Oh?" Liu Feng nodded abruptly, guessing in his heart whether this was something like a soap horn from the other world?

He thought he could make soap, and among the books he brought over, there was a way to make soap, and it seemed that he had to rummage through it when he went back.

"Young Master, are you still patrolling?" Allie touched her hair.

"Go back, Nicole should already be cooking." Liu Feng said with a smile.

Then the group of three left the workshop, got into a carriage, and went to the castle under the escort of the Wolf Warrior Team.

Liu Feng was worried about the soap, and the two beast-eared ladies wanted to go back to take a bath quickly.
