Chapter 155: Choice of dryer

Chen Xin is still hesitant about the form of the tray. Although it is said to

be made into a drawer type, it is undoubtedly a big tray. Is the bottom of the

tray made of iron sheet airtight or made of gauze?

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

The whole cabinet is not difficult to design. It is enough to make a four-

legged closet. As for the bottom, as long as a hot air blower can blow hot air

upward, it is a perfect design.

What embarrassed Chen Xin was the design of the tray used to hold the rice in

the cabinet, and he had difficulty choosing what structure to use.

In the entire cabinet, Chen Xin intends to put about twelve layers of pallets,

so that a lot of rice can be dried at one time under the condition of ensuring

ventilation. Three bags of more than 200 catties of rice can be dried in about

four or five times. dry.

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

The iron tray has better load-bearing capacity and can put a little more rice

on it. However, the load-bearing performance of the gauze net is not very

good. Obviously, the rice that can be held is less. It is very likely that you

have to do more work.

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.

For the gauze, you have to make the frame first, and then fix the gauze, and

the gauze is not fixed by nailing a few nails, but the four sides need to be

pressed tightly with a bead so that it will not fall off of.

The key is that the gauze is not durable, even the steel mesh, if it often

bears heavy objects, it is easy to fall off.

But if you can get the slippery mesh or screen used in the kitchen before, it

is the best. The texture is harder, stronger than steel mesh, and the mesh is

fine, but it has enough air permeability. If you use it for this, It is the

most suitable.

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, 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 Chen Xin wants, and he still needs to assemble the

parts by himself.

So while Chen Xin was drawing design drawings and squeezing his own hair, he

also asked Li Yulong to help him figure out a way to get a grain dryer or some

metal screens.

However, even Li Yulong, who wants to get a trading market, feels a little

embarrassed about this, saying that he will try his best to find it, but there

is no guarantee that he can get it.

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 inside.

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 moisture in the grain by

temperature. Until toasted dry.

This drum type and vertical cabinet type are the two common types of dryers,

regardless of the large, medium and small models, but in relative terms, drum-

type electric heating is undoubtedly more power consumption than the blower.

It is precisely because of energy-saving considerations that Chen Xin still

hopes to use a vertical dryer instead of a drum-type electric heating.

Fortunately, the rice can be stored for a few days after it is harvested. The

dryer is not needed right away, and it is not good. Chen Xin can spread the

grain on the floor of the refuge 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 suitable for

spreading the grain is to connect the shelter gate 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 achieve the

effect of natural air drying.

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

And there is another problem to consider here is that the air humidity inside

the refuge is actually 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 during the first construction of the refuge can

also recover part of the air. However, due to the existence of planting

greenhouses, the air humidity is still relatively high under the effect of

plant transpiration.

Therefore, drying in this way can indeed dehydrate the grain, but it cannot

achieve the effect after the dryer is dried. There will still be a certain

amount of moisture in the grain, which affects storage.

However, if there is no other way, it can only be done.

But before considering these questions, Chen Xin has a more important thing to

do.

That is... cooking!

How can the newly harvested rice not cook a bowl of fragrant rice and taste

the fruits of your hard work?

Dehulling rice is not a troublesome thing. If it is dried or sun-dried rice,

you can rub the husk off the grain by rubbing it with your hands 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. uukanshu.com In rural areas, there are generally grain processing

stations with special machines. After the rice is poured in, the white rice

will come out, and the husks will be collected as chaff.

Bran is a good thing. Although it is just the husk removed from rice, it still

contains certain nutrients. Some scholars have even found that the rice bran

oil contained in the bran can lower cholesterol.

Moreover, the chaff itself is edible. Although the chaff is mostly used to

raise livestock, it was not unusual for poor people to eat chaff in ancient

times.

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 examples of poor

people who have eaten chaff in the past.

Of course, Chen Xin did not eat chaff, but planned to keep the chaff to see if

he could raise some livestock by himself.

You definitely can't raise pigs, but Chen Xin thinks he should still be able

to raise chickens or rabbits.

The only thing is that the seedlings are difficult to obtain. Even if there

are these things in the underground planting area of the city hall, it is

difficult to obtain 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 before the disaster,

the rice that ordinary people ate is the polished rice that has been processed

again, and the skin on the surface of the rice has been milled, 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 retained, the nutritional value is relatively

higher.

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