Corn threshing is highly dependent on labor, and the efficiency of labor is not high. If you go to screen for bad grains and small grains, the efficiency will be lower, and the quality of corn with few bad grains and small grains is not at all too big Everyone is selling like this, so no one has deliberately screened out bad grains and small grains, at least plus the workshop without that idle time, the hawker may clean it up when it ’s okay, so it can be sold at a slightly higher price .

Of course, there will also be some customers who like to take advantage of the small price. When buying corn kernels, they will pick them up by hand, one by one, and pick the best corn kernels, and then buy a half a catty, Whenever such a customer is encountered, the person selling corn kernels will have a headache.

These customers picked up the best and largest corn kernels, so the ratio of remaining bad kernels to small kernels increased relatively. The overall impression of the corn kernels sold in this way is not very good, and the selling price may be affected to a certain extent. Therefore, there will be hawkers who are angry not to sell to such fault-finding people.

Of course, there will be some hawkers who are more generous. Their principle is to pick up and sell them. Finally, little bit bad grains and small grains are left and no one wants to lose them. Some hawkers even put a brand directly to let customers pick them casually. You can pick as much as you want, so that the business will be much better. You can make up for the losses if you run out. This is the smartest way.

These are all men who work, although women can do this kind of work, but I do n’t know why, I watched two workshops in a row, and the work is all men, maybe women go to do more women ’s work Right!

The working man is peeling corn kernels, and when Li An walks over, they all look timidly towards Li An timidly and take a sneak peek from time to time, which is quite interesting.

“Extend your hand to show me.”

Li An walked over to a man who was working and said.

The housekeeper Zhao Xiao immediately bent over and pulled the palm of the still-streaking man.

Li An takes a closer look. This young man has calluses on his palms, a thick layer of calluses, but even if there are thick calluses on the palms, the palms are still worn out. How high is the wear of the palms, this is a more sinful job, maybe it is because it is too hard, so no female workers are recruited, and the previous rice hulling workshop may be because it is necessary to control the donkey, which is also not suitable. woman.

“The palms are worn out, and they are very serious! Why don’t you wear gloves? Isn’t it easy for your palms to be worn out?”

Li An looked at the man with the calluses in his hands and said.

The man smiled and said, “It’s not a hindrance, it’s not so coquettish, hehe.”

The housekeeper Zhao Xiao also busy said: “The working people are like this, it will be fine after a few days of breaking the skin, it’s okay.”

Li An naturally knows that there is nothing to break, but it is better to avoid it. If you are always injured, not only do people suffer, they are not very hygienic in their work, and the blood from the palm of their hands is very unhygienic on food. Well, there are not many strange infectious diseases in this era of Great Tang, maybe it does not matter!

The housekeeper Zhao Xiao was just a real performance, so he blurted out and said that the craftsman’s hand was broken, but he always felt that the word glove was familiar, and after thinking about it, he suddenly realized that it seemed to be a product produced by Li An’s workshop. Is it possible That Li An is here to sell gloves, but it is not reasonable to think about it carefully. What identity is Li An, and there is no shortage of money at home. Even if the gloves are at zero cost, there is not much profit, so you will not come to sell the products yourself.

However, these are not important. Since Li An said that the craftsman should wear gloves, he certainly has to cater to it, so he quickly said with a smile: “Although these rough men work, it does n’t matter much if their palms are broken. But our owner also loves his people. When I look back, I will tell the owner to prepare a few sets of gloves for each of them so that they will not wear their hands later. “

After talking pleased towards Li An.

Li An nodded with a smile, said: “Gloves only play the role of protecting the palm that’s all, not much work without gloves will not break your hands, if you do too much work, even with protective gloves, the palm will be the same It will hurt, it is difficult to avoid completely. It may be good to reduce it at all. The rough man who works is also a human. When the palm is broken during the work, it will hurt. When the palm hurts, the speed of the work will definitely be To some extent, the loss they do a little less is definitely greater than the loss of buying gloves. Is this the reason? “

Regarding Li An ’s teachings, Xiao Xiao ’s housekeeper said quickly: “Minister Li said too much, the villain told the Dong family, the Dong family will not refuse, this will not only protect the reputation of the following people, but also save costs , The good thing of one move, two gains is hard to find, hehe! “

Li An sees too much for this kind of flattering face, so, seeing the performance of this product, I ca n’t make the slightest waves in my heart, and I wo n’t be very proud because others agree with me. For this small A small sense of accomplishment has long been numb.

“How many corn kernels can a person peel?”

Li An asked.

Zhao Xiao’s housekeeper said: “This is not carefully calculated, it is estimated to be about 3 denier! Maybe more.”

Li An hearing this, thinking about it, if the average is only 3 deniers, wouldn’t the labor cost be higher than the rice processing? Think about it, the rice dehulling workshop also has donkeys in addition to labor, and the consumption of donkeys is also very large For a sum of money, the overall processing cost is not much different.

In short, the processing cost is really not low. The cost of processed corn kernels is much different than that of unprocessed corn cobs, which is higher than the difference between rice and rice. If you are a particularly poor poor person, you will still buy corn cobs. After you buy it back, slowly peel it off.

It ’s like the edamame of later generations. The unpeeled 2 yuan per catty, and the 6 yuan per catty peeled, the price difference is as much as 3 times, and the soybean shell of edamame accounts for only 40%. A good edamame should be 3 yuan for 3 pounds, but the result is that it is sold directly for 6 yuan. This is still a conscientious peddler. It is more expensive to sell 7 8 yuan per catty. The expensive one is not outrageous.

But even if it sells for 7 or 8 yuan, it still doesn’t worry about selling, because the pace of life of modern people is getting faster and faster. When the hawkers selling vegetables are idle, they can An’an quietly peel the edamame, and the office workers I ’m very busy. Where can I find the free time for peeling edamame? It takes at least half an hour for a pound of edamame to be peeled. The office worker can pay for it, and it ’s good to be able to cook for himself. There is a huge demand, and there is also no time to peel edamame. Otherwise, if you hire more employees, the cost will be greatly increased, which is higher than the high price of edamame.

According to the wage standards of later generations, it normally costs at least 2 yuan per hour, and a snack can peel a few kilos of edamame, for example, it can peel 4 kilos of edamame, and the material cost is close to 7 kilos, which is 8 9 yuan, labor cost. Ten yuan, a total of seventeen-eighteen pieces, the cost of a pound is close to 7 yuan, which is much more expensive than buying peeled edamame grains, so even if you sell 8 1 bucks, meals are more inclined to buy edamame grains directly As long as there is demand for this in the meal, it will definitely be purchased at a high price.

This is also the case at Great Tang Chang’an City at this time. Except for those who are poor and have too much time to work, they will buy corn cobs directly, and for those who are busy working, they prefer to buy corn kernels directly. There are so many rich people and restaurants in Beijing, and there is a huge demand for corn kernels, which has led to the formation of corn processing workshops.

Unlike ordinary person sitting at home and peeling corn, the efficiency of the workshop is obviously higher. If the average old 100 people are peeling corn at home, there can only be half of the workshop at most, because someone in the workshop is in charge and ca n’t be lazy to rest. There are special grooving tools, so that the speed of peeling corn can be improved a lot, and there is not so much attention to peeling corn at home, and the work speed will be much slower.

Li An saw that these people had a metal knife less than one foot long next to them. The purpose of this tool was to cut a gully for the corn on the cob. Then, the corn kernels below could be peeled off better. After all, the beginning of this Step is the most difficult. Only by opening the slot at the beginning, the next corn peeling can proceed more smoothly. If the slot at the beginning is not opened, it will be very difficult to peel.

Grooving is an effort and a technical task. The cutter is very sharp, but you can’t use too much force when grooving. You must control the strength. When this blade is cut, a row of corn kernels can be more complete Save it, if it is cut too shallow, the corn kernels will be broken, and if it is cut too deep, it will be cut with the cob core, so it is necessary to cut with this strength, a corn cob can be cut with a knife You can also cut a few more knives. Naturally, if the grooving technique is good, you can cut a few more knives. However, if the grooving technique is not good and unskilled, it is enough to cut a knife.

“Give me one, let This Official also try.”

Li An said.

The housekeeper Zhao quickly took a slotted corn cob and gently passed it to Li An’s hand.

Li An broke it with his hand. It was really hard enough. It took some effort to peel off the corn kernels. After peeling a few corns at random, Li An dropped the corn cob.

Looking at these working people grooving corn cobs with original tools, Li An suddenly felt that if this grooving tool can be made into a ring and cut at once, wouldn’t it be possible to cut all the corn kernels, In this way, it is not necessary to strip it, the efficiency can be improved at least several times, and the labor cost can be reduced much better.

From Li An’s point of view, a machine like Research & Development takes almost no time and can get the design drawings in one night. After discussing with the craftsman on 2nd day, the machine can be completely done.

After all, this is a manual machine that does not require power, and there is almost no difficulty. In order to save energy as much as possible, Li An feels that it is necessary to introduce a hand-crank system, which can save more energy, as long as the hand-cranked model comes out, Plus the power can form a real machine, everything is logical, it really takes little time, the corn kernels are large, and the corn cobs are almost almost the same thickness, only for Li An Research & Development threshing machines. The great convenience allows Li An to research and develop machines faster and better, thereby serving the society.

Li An asked his subordinates to take more than a dozen corn cobs and the same number of cobs, ready to take them back to study slowly.

“These This Official is taken away, and a few sets of useful tools will be sent to you in a few days, which is definitely better than the grooving knife here.”

Li An smiled slightly and took everyone back to the Research & Development Center.

Butler Xiao has heard that there will be better tools in a few days. Naturally, I am very happy. If there are really more advanced and easy-to-use tools, it will be really cool.

Li An entire group returned to the Research & Development Center by car and immediately ordered a ruler to measure these corn cobs and corn cobs, each of which was carefully measured to understand these corn cobs and corn cobs The exact size of the core.

Because the corn cobs and corn cobs are exactly the same size, there will always be some discrepancies, so you must measure more to find the average value, which is a reference for the Research & Development tool.

Dozens of cores and corn on the cob were quickly measured. Li An looked at the size. The gap is not very large. Therefore, there is no need to manufacture multiple models of tools. A fixed size machine is enough.

Li An thought for a moment in his mind, and then began to draw the corn peeling tool, the size drawings of various parts, and finally handed these scattered parts drawings to different craftsmen, let them build these parts as soon as possible, it is best to Create more.

These basic parts are very simple, and there are many Research & Development machines and tools at the Research & Development Center at this time, which provides a greater possibility to build various parts, so it is not difficult for the structure to be ordinary The parts can be built quickly, for example, it is a matter of a few hours to build a large blade, and the hand-cranked corn kernel machine drawn by Li An is estimated to be built in one day, and go back to sleep After I felt it, I came to work in the morning on the second day and it was estimated that it could be made. Li An only needs to be assembled. The dimensions are all marked, plus this machine is not very precise, as long as the size error is not Very large, there will be no problems.

After designing the hand-cranked corn threshing machine, Li An sat on the chair and thought about how to design the glove loom and the rice hulling machine. These must also be carefully considered. These all are relatively large machines. From the design It takes a lot of time from manufacturing to final setting. From spring tillage to autumn harvest, it’s only a half year that’s all. Overall, the time is not very sufficient. Research & Development came out second, and mass production It also takes a lot of time. In Beijing, where manpower is scarce, this pressure is not small.
