Chen Xin is still a little hesitant about the form of the tray. Although it is said to be a drawer type, it is undoubtedly still a large tray. Is the bottom of the tray made of iron sheet to be airtight, or is it made of gauze to be breathable
Chen Xin looked at the design drawing he had drawn and fell into hesitation.
The entire cabinet is not difficult to design. It can be made into a four-legged cabinet. As for the bottom, as long as a hot air fan is placed to blow hot air upwards, it will be a perfect design.
What embarrassed Chen Xin was the design of the tray used to hold rice in the cabinet. He had trouble choosing what structure to use.
In the entire cabinet, Chen Xin plans to put about twelve layers of pallets, so that a larger amount of rice can be dried at one time while ensuring ventilation. Three bags of more than 200 kilograms of rice can be dried in about four or five times. Dry.
But the question is whether the pallet should be an iron pallet or a gauze pallet
The iron pallet is better load-bearing, and more rice can be placed on it, while the load-bearing performance of the gauze net is not very good, and the rice it can hold is obviously less, and it is likely that you will have to do one more job.
Moreover, the structure of the iron sheet pallet is relatively simple, and it is relatively easy to make. Just cut a piece of iron sheet, roll up the edges and you are done.
For gauze, you have to make a frame first, and then fix the gauze. And the fixation of the gauze does not mean nailing a few nails, but you need to use pressure strips to tightly press the four sides so that it will not fall off. of.
The key is that gauze is not very durable. Even steel mesh can easily come off if it often bears heavy objects.
But it would be best if you can get the mesh or screen used in the kitchen in the past. The texture is relatively hard, stronger than steel wire mesh, and the mesh is fine, but it has enough breathability. If you use it for this, It's the most appropriate.
It's just that this kind of thing is difficult to get now, and even if it is available, it is not big enough. If you make it yourself, a fine metal mesh? Even with system assistance, it is a troublesome job.
After all, if there are no drawings? With the power of the system, he can only process the materials into the shape Chen Xin wants, but he still has to assemble the parts himself.
So while Chen Xin was drawing design drawings and pulling out his hair, he also asked Li Yulong to help him find a way to get a grain dryer or get some metal screens.
But even Li Yulong, who wanted to get into the trading market, felt a little embarrassed about this and said he would try his best to find it, but there was no guarantee that he would be able to get it.
Chen Xin also felt helpless about this. If he really couldn't find a suitable screen, he could only consider overturning the vertical cabinet design and make it a roller.
The so-called drum is a rotatable cylinder placed horizontally. There are baffles inside. After the grain is put in, the wall of the cylinder is heated by electric heating and rotates at the same time. It uses the temperature to bake the moisture in the grain. Bake until dry.
The drum type and the cabinet type are two common types of dryers, regardless of whether they are large, medium or small. However, relatively speaking, the electric heating of the drum type undoubtedly consumes more power than the blower.
It is precisely because of energy-saving considerations that Chen Xin still hopes to use a vertical hair dryer instead of a drum-type electric heating.
Fortunately, the rice can be stored for a few days after being harvested. The dryer is not needed immediately. And if it doesn't work, Chen Xin can spread the grain on the floor of the shelter and let it dry naturally.
Of course, the efficiency of natural air drying is very low, and it takes up a lot of space. Spreading more than two hundred kilograms of grain is a big puddle. For Chen Xin, the only place he can think of to spread the grain is connecting the shelter door and Internal corridor.
The dozens of meters long corridor has a fully hardened cement surface and is straight and flat. If the grain is spread there, it can indeed have a natural drying effect.
But in that case, it may take a week to dry the grain.
Another issue that needs to be considered here is that the air humidity inside the shelter is actually relatively high. Although the ventilation system will allow some water vapor to be discharged, the water circulation system installed when Chen Xin first built the shelter can also recover some of the water vapor in the air. water vapor, but because of the existence of a greenhouse, the air humidity is still relatively high due to plant transpiration.
Therefore, drying in this way can indeed dehydrate the grain, but it cannot achieve the effect of drying in a dryer. There will still be a certain amount of moisture in the grain, which affects storage.
However, if there is no other way, this is the only way.
But before considering these issues, Chen Xin had a more important thing to do.
That’s it…cooking!
How can you not cook a bowl of fragrant rice with the newly harvested rice and taste the fruits of your hard work
Rice husking is not a troublesome matter. If the rice has been dried or sun-dried, even if you rub it with your hands, you can rub off the rice husk on the grains and turn the grains into brown rice.
However, if the moisture is not removed enough, it can only be processed with the help of tools.
Before the disaster, even in rural areas, few people used manual threshing. Grain processing stations were usually built in rural areas with special machines. After pouring the rice into it, what came out was white rice, and the rice that came out was white. The chaff is also collected as chaff.
Bran is a good thing. Although it is just the husk taken off from rice, it still contains certain nutrients. Some scholars have even found that the rice bran oil contained in bran can lower cholesterol.
Moreover, the bran itself is also edible. Although bran is now mostly used to feed livestock, in ancient times, it was not uncommon for poor people to eat bran.
Whether it is the idiom of eating bran-thick vegetables, or the bran steamed buns or bran fried noodles that are still available in the north, these are all examples of poor people eating bran in the past.
Of course, Chen Xin will not eat the chaff, but plans to keep the chaff to see if he can raise some livestock of his own.
He definitely couldn't afford to raise pigs, but Chen Xin felt that he could still afford to raise chickens or rabbits.
But the key point is that it is difficult to get seedlings. Even if these things are available in the underground planting area of the city government, it is difficult to get them from them.
As for the rice after the bran has been removed, strictly speaking, it is not the rice that everyone often ate before the disaster, because the rice that ordinary people ate before the disaster was polished rice that has been processed again, and the outer skin on the surface of the rice grains has been ground away, that is, The cortex and germ will turn white.
The rice with only the husk removed should be light brown or light brown, which is the brown rice that was popular before the disaster, or also called whole grain.
Because the cortex and germ are retained, the nutritional value is relatively higher.
For Chen Xin, he decided to use pounding method to shell the rice. (End of chapter)
