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

First I went to the canning workshop, then to the brewery and the workshop that produces instant noodles, and now I just finished inspecting the linen workshop.

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

Regarding oil, Enri was extremely curious. There are so many delicacies in the castle, and they are inseparable from oil.

In this world, the only source of oil is from It was obtained from wild boars, and the quantity was very small. Only nobles could afford oil. The price of oil was also very expensive, several times more expensive than salt. The nobles used oil to make some snacks, not for cooking. This was not the case in this era. Most people invented stir-frying by boiling it.

The oil Liu Feng mentioned was peanut oil, which is squeezed from peanuts and is the main oil currently used.

Of course, there is also a vegetable dried fruit oil, which is a product of this era. , but the quantity was relatively small, and was used by Liu Feng to make innocua ointment...

Zuixiao Tower and various gourmet restaurants now use peanut oil, but due to quantity reasons, it is not sold to the outside world for the time being.

And peanuts are growing vegetables in greenhouses. There were a lot of seeds left during the time, and when the land was cleared for farming, they were planted together with potatoes.

"Now that you are here, let’s go and have a look. Liu Feng said softly

"good."Anli responded happily and followed Liu Feng towards the depths of the workshop.

When they arrived at the oil pressing workshop, eight soldiers were guarding the door to prevent irrelevant people from breaking in. After all, oil is such a Liu Feng doesn't plan to let others know about it yet.

In the future, this peanut oil will also be an indispensable thing for ordinary people in daily life. It can be said to be on the same level as salt. After all, firewood, rice, oil, salt, sauce, vinegar, tea

"grown ups."The eight soldiers saw Liu Feng's arrival and saluted quickly.

Liu Feng nodded and walked to the workshop with Mina and An Li.

"Rumble....."

"buzz buzz……"

Before entering the door, the sound of the steam engine could already be heard. In the workshop, three presses were working driven by the steam engine.

The press was made by the Scientific Research Department according to the drawings given by Liu Feng. It is in the shape of a vertical barrel and is driven by a steam engine as the source of pressure.

Pressed peanut oil relies on physical pressure to directly separate the oil from the raw materials, without any chemical additives in the whole process.

Before the steam engine appeared, peanut oil was pressed manually, which was the most primitive way of pressing peanut oil. The amount of oil produced was only enough for a few shops.

Now with the advent of steam engines, the amount of peanut oil has increased, but now it is also limited by peanuts as a raw material

"buzz buzz……"

After Liu Feng and the others entered the workshop, they frowned at the noise, and then looked around carefully.

"Wow, there are so many people shelling peanuts."Anli looked at a bunch of people peeling off peanut shells in surprise.

She knew about peanuts. When she harvested the first batch of peanuts, Liu Feng took some to the castle and asked Nicole to fry them into salty peanut kernels. You can eat it as a snack when you have nothing to do.

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

"Rumble……"

The further inside, the louder the steam engine became.

Liu Feng took Mina and An Li to refer to the stir-frying process. Before pressing the peanuts, some water needs to be removed. The peanuts must be stir-fried until they are 6 to 8 years old before the oil can be pressed.

"So delicious."Enli was holding the peanuts in her hand and stuffing them into her mouth.

"It's quite fragrant, but not salty at all."Mina also commented that it was a little less salty than Nicole's stir-fried peanuts.

"……"Liu Feng rolled his eyes and led the two of them into the pressing workshop.

The stir-fried peanuts are sent to the pressing workshop, and then poured into the funnel-shaped feed port, and then pressed to squeeze out the peanut oil, followed by filtration and precipitation, and the production of peanut oil is completed.

"Hey, this is how the oil comes from."Anli exclaimed, circling the press twice, with little stars in her eyes.

Mina had already met Liu Feng, and was very surprised when she first learned that oil can also be obtained from peanuts. Very surprised. It’s hard to imagine that oil can be obtained from these tiny peanuts. This also lets Mina know that oil can be obtained not only from animals, but also from plants.

"Master, this is so amazing. The food you grow has so many uses."Anli admired that the sugar cane grown can be used to make sugar, and now the peanuts can be used to extract oil.

"Tap tap tap……"

Liu Feng smiled and turned to look at the workshop leader who hurried over.

"Lord City Lord."The person in charge of managing the oil pressing workshop walked over quickly. He was a member of the retired army.

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

"If we can keep up, we even have a lot of surplus, which has all been stored in the warehouse."The person in charge responded

"After some time, I will ask the scientific research department to send you another press. Liu Feng said calmly

"yes."The person in charge responded quickly.

"Open flames are strictly prohibited in the workshop, so be sure to pay attention to this. Liu Feng said seriously.

This place is full of oil. If it catches fire, the consequences will be disastrous.

"Yes, we will definitely pay attention."The person in charge responded respectfully. He was aware of the seriousness of this issue and did not dare to be careless in the slightest.

Liu Feng made a rounds and found no problems before leaving with Mina and An Li. After all, the oil pressing workshop is The smell is really not pleasant after being smelled for a long time.

"Master, after just staying in there for a while, my whole body feels a little greasy."Enri touched her hair and pouted.

"The same thing happened to me last time. I just went back and took a shower with soap."Mina gently helped Liu Feng remove the debris from her body. She just washed her hair yesterday and had to wash it again today.

I don't know why. It used to be troublesome to wash her hair even if it was every day. I don’t find it troublesome to wash my hair.

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

"Master, the soap is running out."Enri whispered.

The first time she took a bath with soap, she found that it could be washed so cleanly and had a light fragrance. Now that she doesn't use soap, she is not used to it. Especially now in summer, after sweating My whole body is sticky, so I need to take a shower with soap.

"Gone?"Liu Feng raised his eyebrows. It has indeed been a long time since the last time he brought soap.

"Well, some of the soaps were given away. Sheeran, Elsa, and Beris all gave away some of their soaps."Anli explained softly.

"By the way, how did you take a shower before without soap?"Liu Feng asked curiously. He didn't pay attention to this before.

You know that Anli was a princess before. Did she also use the same water to take a bath?

"I use Qingbijiao, but it doesn’t wash as cleanly as soap, so it’s incomparable."Anli replied

"Qingbijiao? What is this?"Liu Feng was stunned for a moment. This is the first time he has heard of this thing.

"It is the fruit of a plant, as long as a finger, like a goat's horn."Mina explained softly.

"oh?"Liu Feng nodded clearly, wondering if this was something like saponins from another world?

He thought he could make soap. Among the books he brought over, there were instructions on how to make soap. Look. I have to go back and forth to look for it.

"Master, are you still patrolling?"Anli said while stroking her hair.

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

Then the three of them left the workshop, got on the carriage, and were escorted by the Wolf Warriors team to the castle.

Liu Feng was thinking about the soap, while the two beast-eared girls wanted to hurry up. Go back and take a shower
