Chapter 244: Meat grinder
Just when Shangwen sent the manuscript to the printing factory. A strange invention attracted Shang Wen.
Meat grinder. During work, the raw meat is cut into pieces by the shearing effect formed by the rotating cutting blade and the perforated blade on the orifice, and the raw material is continuously discharged out of the machine under the action of the screw extrusion force.
With the meat grinder, the processing speed and quality of meat products have been greatly improved.
"What's your name?" Shang Wen asked the young man who invented the meat grinder.
"My name is Zhang Zhuan." Said the young man.
"Why did you invent this?" Shang Wen said, pointing to the meat grinder.
"I'm sorry, my family is from South Korea. It was invited by the State of Qin." Zhang Zhuan said. This invitation was obtained by Feng Quji by means of money temptation. Many craftsmen in Shangwen's factory came in this way. They originally wanted to steal the technology, but the initial scale of production equipment has been protected by technology patents, plus a 180-degree change in attitude towards craftsmen. They soon settled down in Qin State. Especially all kinds of machines have opened their eyes. Craftsmen have a natural sense of curiosity. This sense of curiosity touched them deeply. They stayed without even thinking about it.
"My father used to be a carpenter who made bows and crossbows, but he didn't want to work for Qin, so he sold meat for a living. However, his old man is getting older. Especially those who chop into minced meat are very tired. I am very tired. It's machining. That's where the barrel is produced. I saw that a drill can be used to produce the barrel. So, I spent my own money to do this." Zhang Zhuan said.
"You are a good boy, a filial good boy." Shang Wen praised. Filial piety is also one of the driving forces of invention.
"Now, are you willing to apply for a patent for this invention? You can get remuneration for hardware and bond payments. How about?" Shang Wen set out his own terms.
"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, disagreement is your freedom." Shang Wen said disappointedly.
"No, no, no. My lord, you got it wrong. I agree very much. I agree very much. I am just surprised that my, my invention can..." Zhang Zhuan was a little excited, and a little excited, he didn't know what to do. Say. One hand swings up and down. A very exciting action.
"Congratulations." Shang Wen stepped forward and squeezed Zhang Zhuan's hand and said.
"You go to Master Meng Yimeng. He will let you fill out a form. Come on!" Shang Wen smiled and turned and left.
"Come on." Zhang Zhuan replied unclearly.
"What does this mean?" Zhang Zhuan asked suspiciously.
Shang Wen is very happy. Originally planned to take the time to solve Qin Jun's logistics supply problem, but now that he has not caught up, someone has already taken the lead. The reason is so strong.
With a meat grinder, the meat quality will be greatly improved. Sausage, ham, luncheon meat. Wait for a large amount of meat products to be processed. However, some important raw materials are still lacking, especially starch. The output of wheat planted in Qin is too small. Although every household has planted it, but the total area of planting is very pitiful. There is no need to mention the output.
When making ink, when starch is needed as an additive, the method of crushing and grinding powder is used. Shang Wen felt very strange. Under one question. They didn't even know about grinding. The backward processing methods have caused this kind of modern and large-scale popular crops to be delayed in its historical position.
Without any processing methods, there are only one or two simple ways to use wheat. Wheat with husks is difficult to swallow. It is unpalatable and has become a bottleneck in wheat cultivation, but he has more advantages than millet, which is why people plant him.
The postponement of a technology often restricts the subsequent follow-up of a large number of technological inventions. Or it is a small invention that restricts the improvement of human life. Where there is demand, there will be invention.
What Shang Wen wants to do now is to improve the production method of starch. In addition, they 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 when he asked to invent the mill, someone had already begun to try.
The tool I tried to use turned out to be a road roller that was just made and used to build roads. Because the roller equipment is very large. The developers did a small talk, but the primary direction was not to process wheat, but to process a large amount of gunpowder. Especially granular gunpowder.
In the past, in gunpowder processing, the manual method of rolling dough was used. After the raw materials are purified and finely processed, they are mixed with adhesives and finally rolled out by hand.
However, since a large number of gunpowder weapons have been exported to six countries, especially Yan, the order for gunpowder has increased significantly. The granular gunpowder produced by this traditional process can no longer meet the demand for gunpowder production. Moreover, judging from the number of recent orders. Especially since Qin's first gun group appeared, gunpowder processing has been in a state of tension.
Iron abrasive tools were developed under such circumstances. Shangwen didn't know all this.
Shangwen has many things to pay attention to, such as starch processing at present. Now the starch is made by fermentation method, that is, after the wheat is softened and ground with water,
Wheat starch undergoes acid fermentation, so that the cells surrounding the starch granules are dissolved and the starch is easy to separate. However, the loss of gluten in this method is more, and the protein in the starch is not easily depleted, which affects the starch quality.
This method is not advisable, nor can it fully meet the needs of large amounts of food processing. The Martin method is one of the best ways to replace the fermentation method. It uses wheat flour as raw material, adds 50-80% water in a kneader, and kneads the flour into a dough at a speed of 40 rpm. The mixing time is about 30 minutes, and it is placed for 30 minutes to make the gluten swell and bond each other, making the starch easy to separate. Adding an appropriate amount of salt can improve the quality of gluten and promote its bonding. If there is too much free acid in flour, add proper amount of calcium hydroxide to adjust its pH value. After the dough rests temporarily, add 5 to 8 times of water to knead and wash, knead and wash in 3 to 4 times. The washed emulsion is starch milk, which needs to be refined and purified. The remainder is gluten, with a moisture content of 65-70%. After drying, the protein content is about 75-85%. It can be eaten or used as a raw material for making oily gluten. .
As for some processing details. Especially the acid test can only be tested through the human nose and mouth. Fortunately, it is not a hazardous chemical. This method must be promoted quickly. Because logistical pressure has always been a problem for the army, soldiers can only fight well if they eat well.
