Space Food Storage: Daily Travel

Before Huo Dong came back, Liu Yuhan had already produced the first batch of vegetable oils in the newly built oil press workshop, including peanut oil and soybean oil.

Peanut oil must be made from good raw materials. Good oil cannot be produced from poor raw materials.

The main steps in making peanut oil are crushing, steaming the embryo, frying, pressing, cold filtering, and storage.

This traditional oil pressing method produces high-quality oil with high purity and rich aroma. It can be stored for a long time without spoiling. However, the process is complicated, time-consuming and labor-intensive. However, the vegetable oil obtained is worth it.

Extracting soybean oil is a little different.

First, you need to boil the beans, and then wash the enzyme. Wash the soybeans with water after the enzyme is fermented.

Then soak, add 1-5 times the amount of hot water to the washed soybeans each time, and soak repeatedly.

The last step is to boil the oil. Pour the mixed soaking liquids of soybeans into a pot, boil it over high heat, and then simmer it over low heat until the soaking liquid becomes thick. This is how soybean oil is made.

Such simple soybean oil is produced, but the purity is not very high due to the immature technology.

But Liu Yuhan was already very satisfied with the peanut oil and vegetable oil. He packed them into clay pots of the same size, about 5 jin (approximately grams) each, and sealed them with oilcloth. He first tried selling them at the Huo Family Grocery Store in the prefectural capital.

100斤的干花生仁，大概能榨出30~35斤花生油。100斤的黄豆，大概能榨出20~25斤的黄豆油。

100 jin of soybeans and peanuts would cost at least 5 liang (approximately grams) of silver, including costs and labor. Therefore, a -jin earthenware jar was sold for a flat liang (approximately grams) of silver. They were sold out shortly after they were put on display. Everyone knows that every new product released by the Huo Family Grocery Store is always the most special and premium.

Huo Dong finally returned early before the New Year. He brought good news to Liu Yuhan. He passed by the territory of Wen Tianming, the prefect of Yiyang City. Wen Tianming's jurisdiction included an iron mine. Huo Dong had already ordered Huo San to load a few trucks and return after him.

Liu Yuhan was very happy and asked the housekeeper to prepare the limestone and clay in advance and put them in the farm.

"Are you so happy?" Huo Dong held her in his arms after taking a shower. He really missed her so much!

"Well, I'm very happy. Thank you Yan Ping." Liu Yuhan took the initiative to kiss him.

"Well, I missed you..."

...........................

This was Liu Yuhan's fifth year in the ancient world. She had her own little family, and like any other family, they worshipped their ancestors and General Huo and his wife. In the small kitchen, she helped Liu Yuhan prepare delicious food. On the second day of the Lunar New Year, Liu Yuhan and Huo Dong returned to her parents' home.

Fulai Village is bustling with activity during the Lunar New Year. Its population has surged in recent years. In addition to the new arrivals, some existing residents who had their old homes moved back to Fulai Village. Adding the workshop workers, the village now has over a thousand residents. The workshop's 30 small apartments are almost full of married couples and their children.

The new year has passed, and Huo Dong is not in a hurry to return to the military camp. He is now studying cement in the farm with Liu Yuhan and Huo Qi.

The three main raw materials of cement are limestone, clay and iron ore.

……

Huo Dong personally mixed cement and water, spread it on the pre-prepared yard, and waited for it to solidify. The initial setting time of cement is at least half an hour, and for it to fully solidify, it can take from half a week to more than a month, depending on the temperature.

Half a month later, stepping on the solid water land of Zhuangzi, Huo Dong and others were filled with excitement!

He took the cement and the solidified lumps of cement and rushed to the capital to find the emperor, and gave him the method of making ice.

The emperor was overjoyed! Knowing that these were the ideas proposed by Mrs. Huo Dong, he waved his hand and conferred the title of Fu'an County Lady on her. Changle County was the county lady's fiefdom.

This news shocked Fu'an City! Who could have imagined that an ordinary peasant girl would not only become General Huo's wife, but also possess such extraordinary abilities?

Cement was produced in large quantities and was first used to build city walls and reinforce city defenses. Later, it was used to repair embankments, build bridges and roads, and construct houses... With cement, all of these tasks became much more efficient.

Later, Liu Yuhan and Huo Qi's research team developed papermaking from bamboo and movable type printing... Nanlin Country once became an infrastructure maniac.

Because of the emergence of cement, explosives, strong soldiers, a series of high-yield crops and a series of policies to improve the country and the people, Nanlin Kingdom later became the most powerful country in the surrounding areas.
