Chapter 98
Pressure Tool
"If the pancake is made too slowly, there won't be so much oil in the end. If there is too much oil, you have to pour it in quickly and wrap it quickly to prevent part of the sultry steam inside from disappearing."
Before Xue Wen could speak, Xue Darong was so angry that he hit Xue Wen several times: "Didn't you tell us at that time that we could just wrap it up slowly? Why did you say you were in a hurry? Let us not be so tired!"
Qian Caiyu also scolded him.
Even his wife couldn't help but whispered: "No wonder the oil squeezed out in the end is not only of poor quality, but also not much..."
Xue Wen really wanted to cry.
Xue Yan was made a little embarrassed.
Jiang Yue had no expression and walked forward again.
The front is where the actual oil extraction begins.
Naturally, if you want to extract oil, you need to use a press.
This press is made of two arms thick wood.
The middle of the wood is hollowed out to hold the oil wrapped in cakes. A small hole will be drilled underneath, and the oil will flow out from this small hole.
Jiang Yue stood on her toes and looked at it, then squatted down and looked at it again, and found that there was nothing wrong with the pressing tool.
There's no problem with a hammer. Just drive the deed in hard and squeeze the oil cake, and the oil will flow out. Just use something to catch it below. As long as you have enough strength to swing the hammer, there's nothing else you need to pay attention to.
The oil cake after pressing out the oil is dry cake.
If it is rapeseed, the oil inside will not be completely squeezed out in one press. The cake needs to be crushed, steamed, wrapped, and squeezed again, and a lot of oil will be obtained.
Xue Wen has seen this in the oil shop in town and knows about it.
Jiang Yue didn't say anything about this, but said: "The things used for oil extraction, my grandfather told me, are the same as what you are here. You should really have some problems with the operation during the oil extraction process.
There are some things that I didn't notice, and that's why I'm like this. By the way, cousin, what's the difference in the oil you squeezed out, can you tell me?"
"I won't talk about the oil because it has a strange smell and is sour." Qian Caiyu, the auntie, was a cheerful person and answered for her eldest son first.
Jiang Yue nodded, knowing better.
That's rancidity.
But this rancidity is so profound that they cannot understand it.
Jiang Yue did not speak in a direction that they could not understand, but tried to be as simple as possible: "I heard from my grandpa that the fried oil must be filtered many times to prevent any precipitation. If there is any precipitation in the oil,
If you leave it there, the oil will easily become sour and have a strange smell."
In fact, it is because there is something in the sediment that accelerates the oxidation and rancidity of oil.
How did Xue Wen and the others know this? They just listened to whatever Jiang Yue said and thought about what they did at that time.
When they thought about it, they all grimaced: "It has been filtered many times, but there is still some sediment. Is that so..."
"Is there anything else?" Xue Darong asked urgently. He was worried at first, thinking that Jiang Yue, a child, might not be of much help in the end.
But what if it really helps.
It was with this little hope that he came to see it together.
But the more Jiang Yue said, the more he felt it made sense, because his family didn't do that at the time, so he naturally believed Jiang Yue's words more and more.
Xue Wen, Xue Wen's wife, and Qian Caiyu also looked at her eagerly.
They also completely believed her words.
Jiang Yue said: "Also, the oil must be sealed well and cannot be placed in a place where the temperature is too high. It is best to store it in a cool, dry place without sunlight."
