Chapter 155

Chen Xin still hesitated about the form of the tray. Although he said he wanted to make it drawer type, it was undoubtedly a big tray. Is the bottom of the tray made of iron sheet airtight or gauze mesh airtight?

Chen Xin looked at the design drawing he drew and fell into hesitation.

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

What makes Chen Xin feel embarrassed is the design of the tray used to hold rice in the cabinet. He has made a mistake in choosing the structure to use.

In the whole cabinet, Chen Xin plans to put about 12 layers of pallets, so that he can dry more rice under the condition of ensuring ventilation. Three bags of more than 200 Jin rice can be dried in four or five times.

But the question is whether the pallet should be made of iron sheet or gauze mesh?

The iron tray is more load-bearing, and it can put more rice on it. However, the load-bearing performance of the yarn mesh is not very good. Obviously, it can hold less rice, and it is likely that you will have to do more work.

Moreover, the structure of the iron sheet tray is relatively simple, and it is relatively easy to do. If you cut a piece of iron sheet and roll an edge, you will be finished.

In the case of gauze mesh, the frame must be made first, and then the gauze mesh shall be fixed. And the fixation of gauze mesh does not mean that it is finished by nailing a few nails. Instead, it needs to press the four sides tightly with a pressing strip, so that it will not fall off.

The key is that the yarn mesh is not durable, even if the wire mesh is often heavy, it is easy to take off the yarn.

But if you can get the leaky mesh or screen used in the kitchen before, it's the best. It's hard, stronger than steel mesh, and the mesh is fine and dense, but it has enough air permeability. It's the most suitable one to do this.

It's just that it's hard to get this kind of thing now, and even if there is one, it's not big enough. If you make that kind of fine metal mesh by yourself, even if you have system assistance, it's a laborious job.

After all, if there is no drawing, with the help of the power of the system, it is only to process the materials into the shape Chen Xin wants, and the assembly of parts still needs his own hands.

So while Chen Xin was drawing designs and collecting his hair, he also asked Li Yulong to help him find a way to get a grain dryer or some metal screens.

However, even Li Yulong, who wants to get the market, feels a bit embarrassed and says that he will try his best to find it, but there is no guarantee that he can get it.

In this regard, Chen Xin also feels helpless. If he really can't find a suitable screen, he can only consider overturning the vertical cabinet design and making it into a roller.

The so-called roller is a rotatable cylinder placed horizontally. There will be baffles in it. After the grain is put in, the wall of the cylinder will be heated by electric heating and rotated at the same time. The moisture in the grain will be baked by temperature until it is dry.

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

It is also because of energy-saving considerations, Chen Xin still wants to use the vertical dryer instead of drum type electric heating.

Fortunately, the rice can still be stored for a few days after harvest. The dryer is not needed immediately, and it is not enough. Chen Xin can spread out the grain on the floor of the shelter and dry it 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 200 kilograms of grain is also a big pool. For Chen Xin, the only place he can think of to spread the grain is the corridor connecting the gate of the shelter and the interior.

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

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

There is also a problem to be considered here, that is, the air humidity inside the shelter is relatively high. Although the ventilation system will allow part of the water vapor to be discharged, and the water circulation system installed by Chen Xin when he first built the shelter can also recover part of the water vapor in the air, due to the existence of planting greenhouses, the air humidity is still relatively low under the effect of plant transpiration It's higher for me.

So this drying can make the grain dehydrate, but it can't achieve the effect of dryer drying. There will still be some moisture in the grain, which will affect the storage.

However, if there is no other way, we can only do so.

However, before considering these issues, Chen Xin has a more important thing to do.

That is cook rice!

How can you taste the fruits of your hard work without cooking a bowl of delicious rice?

Rice husking is not a troublesome thing. If it is dried or sun dried rice, even if it is rubbed by hand, the husk on the grain can be rubbed off, making the grain turn into brown rice.

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

Before the disaster, even in the countryside, few people use manual threshing. Generally, there are grain processing stations and special machines in the countryside. After the rice is poured in, white rice will come out, and the husks will be collected as chaff.Bran is a good thing. Although it's only the husk from rice, it also contains certain nutrients. Some scholars even found that the rice bran oil contained in bran can reduce cholesterol.

Moreover, the bran itself can be eaten. Although most of the bran is now used to raise livestock, it is not unusual for poor people to eat bran in ancient times.

Whether it's the idiom eat bran pharyngeal vegetables, or the northern region now has bran Wotou or bran fried noodles, this is the poor people used to eat bran in the past.

Of course, Chen Xin doesn't eat bran. Instead, he plans to keep it to see if he can raise some livestock himself.

Pigs are certainly not affordable, but Chen Xin thinks he should be able to afford chickens or rabbits.

It's just that it's difficult to get seedlings. Even if there are these things in the underground planting area of the municipal government, it's difficult to get them from them.

As for the rice after bran removal, strictly speaking, it is not the rice that people often eat before the disaster, because before the disaster, the rice that ordinary people eat is refined rice after reprocessing, and it will turn white only after the husk, that is, the cortex and germ, on the surface of the rice grain is milled.

The rice with only husks removed should be light brown or light brown, which was popular before the disaster, or whole grain.

Because the cortex and germ are preserved, the nutritional value is relatively higher.

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