Just when Shang Wen sent the manuscript to the printing house. A strange invention attracted Shang Wen.

Meat grinder. During the work, the raw meat is minced by the shearing action formed by the rotating cutting knife edge and the eyelet blade on the orifice plate, and the raw materials are continuously discharged out of the machine under the action of the screw squeezing force.

With the meat grinder, the processing speed and quality of meat products have been greatly improved.

"What's your name?" Shangwen asked the young man who invented the meat grinder.

"My name is Zhang Zhuan." The young man said.

"Why did you invent this?" Shang Wen pointed to the meat grinder and said.

"I'm sorry, my family is from Korea. It was invited by the Qin State. Zhang Zhuan said. This invitation was obtained by Feng Qujian by tempting him with money. Many of the craftsmen in Shangwen's factory came in this way, originally they wanted to steal the technology, but the production equipment that began to take shape has been protected by technical patents, and the attitude towards craftsmen has changed 180 degrees. They soon settled down in the state of Qin. In particular, the variety of machines opened their eyes. Artisans have a natural sense of curiosity. This curiosity touched them deeply. They didn't have to think about it and stayed.

"My father was originally a carpenter, making bows and crossbows, but he was unwilling to serve the Qin State, so he sold meat for a living, but he was an old man and old. Especially those who are chopped into minced meat, especially tired. I'm machining. That's where the barrel is made. I saw that it was possible to produce a barrel using a drill. So, I did this at my own expense. Zhang Zhuan said.

"You are a good boy, a good boy of filial piety." Shang Wen said approvingly. Filial piety is also one of the driving forces of invention.

Now, are you willing to patent this invention? You can get paid about hardware, bonds paid. What do you think? Shang Wen set his own conditions.

"Of course, you can also continue to improve, if you promote it on a large scale, others will pay you royalties." Shang Wen said.

"This. This," Zhang Zhuan hesitated.

"Forget it, it's your freedom to disagree." Shang Wen said with some disappointment.

"No, no, no. Your Excellency, you misunderstood. I couldn't agree more. Couldn't agree more. I'm just amazed that mine, my invention can ・・・・・" Zhang Zhuan was a little excited, excited and didn't know what to say. Swing one hand up and down. A very exciting move.

"Congratulations." Shang Wen stepped forward and clasped Zhang Zhuan's hand and said.

"You go to Lord Meng Yimeng. He'll ask you to fill out a form. Come on! Shang Wen smiled and turned to leave.

"Come on". Zhang Zhuan replied inexplicably.

"What does that mean?" Zhang Zhuan asked suspiciously.

Shangwen was delighted. Originally, he planned to take the time to solve the logistics supply problem of the Qin army, but now he didn't catch up, and someone had already taken the lead. And for good reason.

With a meat grinder, the quality of the meat will be greatly improved. Sausages, ham sausages, luncheon meats. and so on a large number of meat products can be processed. However, there is still a lack of some important raw materials, especially starch. The yield of wheat grown in the Qin State was too small. Although every household has planted it, the small ones are very pitiful. Needless to say, the yield is not to be mentioned.

When making inks, when starch is needed as an additive, the method of mashing and grinding is used. Shang Wen thought it was very strange. Under a question. They didn't even know about grinding. The backwardness of processing methods has led to the delay in the historical status of this modern large-scale popularization of crops.

There is no processing method, so there are only one or two simple ways to use wheat, and wheat with husk skin is difficult to swallow. It is unpalatable and becomes the bottleneck of wheat cultivation, but it has more advantages than millet, which is why people will plant him.

The delay in the emergence of a technology often restricts the subsequent follow-up of a large number of technological inventions. Or a small invention that restricts the improvement of human life. Where there is demand, there will be invention.

What Shangwen has to do now is to improve the way starch is produced. In addition, they also have to send someone to invent the mill, in fact, Shangwen doesn't need to ask them to understand. What Shang Wen didn't expect was that just when he asked to invent the mill, someone had already started to try.

The tools I tried to use turned out to be just made and used in the construction of road rollers. Due to the large size of the roller equipment. The developers made small talks, but the first direction was not to process wheat, but to process large quantities of gunpowder. Especially granular gunpowder.

In the past, gunpowder processing was done by hand like rolling dough. The raw materials are purified and finely processed, mixed with binders, and finally rolled by hand.

However, since the export of a large number of gunpowder weapons to the six countries, especially the Yan country, orders for gunpowder have increased significantly. The granular gunpowder produced by this traditional process can no longer meet the needs of gunpowder production. And, judging by the number of recent orders. Especially after the appearance of the first musket regiment in the Qin State, gunpowder processing has been in a state of tension.

Iron abrasives were developed under such circumstances. Shang Wen didn't know all this.

Shangwen has a lot of things to pay attention to, such as the current starch processing. At present, the starch preparation adopts the fermentation method, that is, after the wheat is soaked and ground with water, the wheat starch is fermented with acid, so that the cells surrounding the starch granules are dissolved and the starch is easy to separate, but the loss of gluten in this method is more, and the protein in the starch is not easy to be exhausted, which affects the quality of starch.

This approach is not desirable and does not fully meet the large number of food processing needs. The Martin method is one of the best ways to replace the fermentation method. It is made of wheat flour as raw material, adding 50~80% water in the mixer, and kneading the flour into a dough at a speed of 40 rpm. The mixing time is about 30 minutes, and it is left for 30 minutes to make the gluten swell and stick to each other, so that the starch is easy to separate. If an appropriate amount of salt is added, the quality of gluten can be improved and its adhesion can be promoted. If there is a lot of free acid in the flour, an appropriate amount of calcium hydroxide can be added to adjust its pH value. After the dough is temporarily rested, add 5~8 times of water to knead and wash it in 3~4 times. The washed out ru-like liquid is starch ru, which needs to be refined and purified, and the rest is gluten, with a moisture content of 65~70%, and after drying, the protein content is about 75~85%, which can be eaten or used as a raw material for making oil gluten.

As for some processing details. The acid test, in particular, can only be tested through a person's nose and mouth. Fortunately, it is not a hazardous chemical. This approach must be rolled out at an accelerated pace. Because logistical pressure has always been a difficult problem for the army, soldiers can only fight well if they eat well.
