Why is the ice cubes of the beverage shop always depressed?Others are directly hollow!

Although it was mid -September, the weather was still hot in the belly sticker, and I heard that it started to cool down in November. I just want Dun, DUN, DUN Called frozen drink). Cola plus ice, happy upgrade! This also made the editor discover one thing, that is, the ice cubes in the cold drink shop, there is always a concave, and even encountered hollow ice. Like the ice cubes below, you can clearly see that there is a depression. Why is this?

Answer Dang, DANG, DANG, DANG quickly invited out! In fact, it is because the square ice cubes in the cold drink store must be made in batches. This is also one of the reasons why frozen drinks in many Hong Kong tea restaurants will be 2,3 yuan more expensive than hot drinks. After asking a few shops, they said that it was Hong Kong's inch gold. Putting a ice maker is very space, and it will collect more money.

Ice -making machine

Today, let's take a look at the heroes behind milk tea and cold drink shops and various fast food restaurants and tea restaurants. Why can it make a transparent but a little depressed ice cubes!

Mesh ice model

From the above figure, we can see that there is a square metal groove next to the ice cubes. This is the core of our refrigeration, that is, the following grid board, which realizes parts with water heat transfer function. On the other side of it is a curved copper tube. The refrigerant flows through the copper pipe, which can also take away the calories on the metal board.

Frozen water

The temperature of the water flowing through the ice mold decreased, and the water was freezing. It was ... the cold ice rain shot hard on the face.

Because of the heat -conducting reasons, ice will start frozen from the side and bottom of the metal grid, and the middle and flowing sides are not so easy to freeze.

Those who make large ice cubes in batches are also frozen outside and then inside.

The way to make transparent ice is that the peripheral transparent ice can be made above, and the problem of ice core impurities is solved by continuous suction. Every time, the machine changes the water in the middle of the container once to ensure that the impurities have been removed before frozen. It can be said that it is very luxurious ...

And using flowing water to freeze, similar to changing water in the middle of the ice cubes, it plays the role of impurities that are not easy to freeze. This is why the ice cubes made by ice machine will be transparent than ourselves!

Heating

When the ice cubes reaches a certain thickness, the camp must change, so that the ice cubes must quickly fall off ... After stopping the refrigeration, start heating. The whole row of ice cubes can quickly fall into the ice storage tank and become separated ice. Essence The store can also shovel and use it at any time ~

After speaking, the square depression ice cubes, and then you have to talk about another, the hollow bullet ice cubes.

Bullet ice machine

The ice cubes of this seed warhead are usually made of smaller ice makers in the following figure. This is not frozen by flowing water.

Turn the sink up first, and then start watering.

When the water reaches a certain height, it starts to freeze.

The ice cubes will start frozen along this metal tube, so the ice made from back is hollow, and there is a feeling of slowing the crystal nucleus. It can be seen that it will start frosting on the tube. It is not recommended to lick, not sweet, and it is easy to taste the bloody smell. Bleak

When the ice reaches a certain thickness, enter the ice -cutting program.

Start off the ice, crackling, crackling, not lazy, crackling, crackling, la la la la la la me ~

Quick ice?

There may be little cute asking how the ice cubes of this ice maker fell in an instant? It happens to have a picture and the truth to solve this problem! Note that the good show is about to open ~ I saw the metal tube full of frosthua instantly, and the metal color was restored instantly, and the cream was condensed into dew. The same is heated by condensation tube, the conversion is extremely fast, and naturally there will be no adhesion, so the ice cubes can be removed in an instant ~

Similar to the principle of warm water demolition, it is to rely on the hot and cold conversion in an instant.

After the mold is removed by a warm water pool, it is a row of type of ice cream.

After that, the ice cubes are promoted to the ice slot, and the ice can be continued ~

The small ones above are also home, only ten ice cubes of two rows at a time, the ice production is really a bit low. The following types of batch, looking at it at a glance, seem to have six or seven rows, and there are more than a dozen ice cubes in each row. This efficiency is enough to relieve the heat in the store!
