Doomsday Bunker Upgrade Chapter 154: The choice of dryer

Chen Xin is still a little hesitant about the form of the tray. Although it is said to be made into a drawer type, it is undoubtedly a large tray. Is the bottom of the tray made of iron sheet airtight or made of gauze? ?

Chen Xin was hesitant to look at the design he had drawn.

The whole cabinet is not difficult to design, it can be made into a four-legged cabinet. As for the bottom, as long as there is a hot air blower, it is a perfect design to be able to blow hot air upward.

What embarrassed Chen Xin was the design of the tray used to hold the rice in the cabinet. He had difficulty choosing what structure to use.

In the whole cabinet, Chen Xin intends to put about twelve layers of trays, so that he can dry a lot of rice at a time while ensuring ventilation. Three bags of more than 200 catties of rice, about four or five times. All can be dried.

But the question is whether the tray should be a metal tray or a gauze tray?

Iron trays are better load-bearing, and you can put more rice on them. However, the load-bearing performance of the gauze is not very good, and the rice that can be held is obviously less, which may make you work one more time. .

Moreover, the structure of the iron sheet tray is relatively simple, and it is relatively easy to make. Cut a piece of iron sheet and roll the sides.

In the case of gauze, the frame has to be made first, and then the gauze is fixed. The gauze is not fixed by nailing a few nails, but needs to be tightly pressed against the four sides with beading. will not fall off.

The key is that the gauze is not durable. Even the steel mesh, if it is often subjected to heavy objects, it will easily fall off.

But it would be best if you could get the slip screen or sieve that was used in the kitchen in the past. The texture is harder, stronger than steel mesh, and the mesh is fine, but it has enough air permeability. This is the most appropriate.

It’s just that this kind of thing is hard to get now, and even if it is available, it’s not big enough. If you make it yourself, the fine metal mesh will be troublesome even with system assistance.

After all, if there is no drawing, the power of the system is only to process the material into the shape that Chen Xin wants, and he still needs to assemble the parts by himself.

So Chen Xin asked Li Yulong to help him find a way to get a grain dryer or some metal sieves while he was drawing design drawings and brushing his hair.

However, even Li Yulong, who wants to gain access to the trading market, feels a little embarrassed about this, saying that he will try his best to find it, but there is no guarantee that it will be available.

Chen Xin also felt helpless about this. If he couldn't find a suitable screen, he could only consider overturning the cabinet-style design and make it into a drum.

The so-called drum is a horizontally rotatable cylinder with baffles in it. After the grain is put in, the wall of the cylinder is heated by electric heating and rotates at the same time to bake the grains with temperature. moisture until dry.

This kind of drum type and vertical cabinet type are two common types of dryers, no matter large, medium or small models, but relatively speaking, the electric heating of the drum type is undoubtedly more power consumption than the blower.

It is precisely because of energy conservation considerations that Chen Xin still hopes to use a vertical dryer instead of a drum-type electric heating.

Fortunately, these rice grains can be stored for a few days after they are harvested. The dryer is not needed immediately, and it is really impossible. Chen Xin can also 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. The spread of more than two hundred catties of grain is also a large pool. For Chen Xin, the only place he can think of is suitable for spreading the grain is to connect the refuge. The door and the inner corridor.

The tens of meters long corridor is a fully hardened cement surface, and it is straight and flat. If the grain is spread out there, it can indeed have a natural air-drying effect.

But in that case, it may take up to a week to dry the grains.

Another issue to consider here is that the air humidity inside the evacuation shelter is actually relatively high. Although the ventilation system will allow some water vapor to be exhausted, the water circulation system installed by Chen Xin during the first construction of the evacuation shelter can also be recovered. Part of the water vapor in the air, but because of the existence of the planting greenhouse, the air humidity is still relatively high under the effect of plant transpiration.

So drying in this way can indeed dehydrate the grains, but it cannot achieve the effect after drying by the dryer. There will still be a certain amount of moisture in the grains, which affects storage.

However, if there is no other way, this is the only way to do it.

But before considering these questions, Chen Xin has one more important thing to do.

That's... cooking!

How can you not cook a bowl of fragrant rice for the new rice you just harvested, and taste the fruits of your hard work?

The husking of rice is not a troublesome thing. If it is dried or sun-dried rice, even hand rubbing can remove the husk from the grain and turn the grain into brown rice.

However, if the moisture removal is not enough, it can only be processed with tools.

If it was before the disaster, even in rural areas, few people used manual threshing~IndoMTL.com~IndoMTL.com~IndoMTL.com~In the rural areas, there are generally grain processing stations with special machines. After the rice is poured in, white flowers will come out. the rice, and the husks are collected as bran.

Bran ​​is a good thing. Although it is only the husk from the rice, it still contains certain nutrients. Some scholars even found that the rice bran oil contained in the bran can lower cholesterol.

Moreover, the chaff itself is also edible. Although the chaff is mostly used for raising livestock, in ancient times, it was not unusual for the poor people to eat the chaff.

Whether it is the idiom eating bran throat vegetables, or the bran wotou or bran fried noodles that still exist in the north, these are all examples of poor people who have eaten chaff in the past.

Of course, Chen Xin will not eat the chaff, but intends to keep the chaff to see if he can raise some livestock by himself.

Pigs and other things are definitely not affordable, but Chen Xin thinks he should still be able to raise chickens or rabbits.

The key thing is that seedlings are difficult to get. Even if there are these things in the underground planting area of ​​the city hall, it is difficult to get them from them.

As for the rice after removing the bran, strictly speaking, it is not the rice that everyone usually eats before the disaster, because the rice that ordinary people ate before the disaster was the polished rice after reprocessing, and the skin on the surface of the rice grains was removed. , that is, the cortex and germ, will turn white.

The rice that really only removes the husk 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 preserved, the nutritional value is relatively higher.

For Chen Xin, he decided to hull the rice by pounding.
