Coffee roaster: introduction of Coffee instrument Party's third play three beans 500X Coffee Roaster

1. Manufacturing principle of roaster

At present, there are mainly three kinds of mainstream roaster, direct fire type, semi-direct fire type (semi-hot air) and hot air type. In addition to the different heating efficiency produced by different principles, the most important thing is that it will have a direct impact on the operation process of the machine and the baking results. It is difficult to simply say which of the three heating methods is good or bad, because different occasions will have different needs, the most important thing is to see the needs of the bakers themselves and what kind of results they want to present.

two。 Heating mode

The main heating methods are gas and electric heating, which is the mainstream choice in the market at present. Basically, those who can choose gas will choose gas, because the firepower is easy to control and the operating range is large. in contrast, the temperature of electric heating is difficult to control, especially the heating rate can not reach the elasticity of gas. In addition, there are charcoal fire, but not much, mainly in Japan, some bakers like to use, in order to bake a different flavor.

3. Baking capacity

The size of the roaster starts from 250g, 500g 1kg, 2kg, tens of kilograms and even hundreds of kilograms. This really depends on personal needs, 250g-500g is enough for daily use. The 500g model can even handle some small coffee shops or be used as a coffee sample roaster.

4. Brand and price

At present, there are really many kinds of coffee roasters on the market, from domestic to commercial. Because I bought a household one before, I didn't think much about it this time, or at least I had to buy a quasi-commercial one. Brands, like most goods, are imported and made in China. Fuji in Japan, Diedrich in the United States, Probat in Germany, Giesen in the Netherlands, etc., in addition, South Korea and Taiwan also have production, although the domestic coffee market is not very good, but the production of roasters is extremely prosperous, casually searching the Internet is a lot, worthy of being the factory of the world. With so many roasters, I studied online for more than half a year, and finally chose a few among the prices I was willing to pay, domestic HB and SanDouke, Fuji discovery 250g, Taiwan Yangjia 800N.

The final choice of the machine is the top version of the domestic SanDouke 500X semi-direct 500g roaster, which is basically what the seller said. As for the size of the roaster, I play at home by myself, 500g is enough. Originally wanted to choose the electric heating type, because it is convenient, but there is no way to change the power supply at home, even if the cable is changed, we still have to take the open line, which is very ugly. In the end, I didn't choose the other three, first, because of the price, and second, because I couldn't connect to the computer to read the data. in fact, I could change the HB, but I wanted the embedded one. The machine was ordered in November last year. I predicted that the machine would be received by mid-January at the latest, but the intermediate seller sent my machine to someone else by mistake. Finally, I received the machine two days before I went back to my hometown. There are still some twists and turns after receiving the machine. I'll talk about it later.

This is the main body of the roaster, but not the final look, because there are still some parts that need to be assembled.

This is the part that needs to be assembled, such as sampling spoon, silver skin collecting tube, exhaust fan, data cable, bean slot, etc. Before, it was said that the seller sent my machine wrong, but later he gave me a replacement, but because the cooling fan was out of stock, I received the cooling fan after I received the machine. Finally, I got the cooling fan after I came back from my hometown.

Start from the gas, the pipe bought a good pipe, this thing safety first, 9mm thick.

A pressure reducing valve needs to be installed after the pipe is connected to the machine. However, it later proved that this pressure relief valve is not suitable, because the previous model is 2 stoves, the new version is changed to 4, requiring greater intake pressure.

After tossing about this, adjustable pressure reducing valve, but the firepower still can not keep up with, the household is no longer suitable, have to go up to the medium pressure valve, there is no time for the recent festival, can only temporarily use a small firepower.

The main body of the machine should be connected to the silver collection bucket, and the exhaust also goes from here.

This is the exhaust fan, which produces the hot air inside the machine and sucks away the silver skin of the coffee beans at the same time. It is installed on the top of the silver leather collection tube. In use, the exhaust efficiency of this fan is not high, and then you will consider replacing this one when you have time.

Connect the computer data cable, which is used to read the internal temperature of the machine, mainly exhaust temperature and bean temperature, which is the legendary recording baking curve. Compared with recording and drawing by hand, it is of course the most convenient and convenient to record automatically while baking, which is also a very important reason why I chose this machine. I thought installing this thing was similar to installing a printer, but it hurt me a lot. I debugged for two consecutive nights before the Spring Festival, but it didn't work in the end. Finally, the seller said to mail me a new converter that supports win8. Originally, I was going to use MBA for testing, but I gave it up because of incompatibility.

This is the control area and instrument area of the machine. The three electronic watches on the left are bean temperature, exhaust temperature and timer from top to bottom. The following four buttons from left to right are power, ignition, cooling, and stirring. The round one on the right is the gas pressure, and the one below is the gas size adjustment.

The boiler and the silver collection trough under the cooling plate.

Cooling plate

Put beans in the mouth.

Exhaust valve adjustment. One of the gimmicks of this machine is that it has a 100-level exhaust regulation compared to other roasters, which makes little personal sense in actual use, unless someone can prove that using 0.8 exhaust during dehydration will taste better than 0.5. No, no, no.

Sampling spoon and observation port.

This is another gimmick for the seller-the adjustable speed boiler. In practice, it seems to be a gimmick at present. I basically freeze on high because there will be a harsh noise when I set it to 60-80. Similarly, if it turns out that the fried beans with a boiler speed of 60 to 80 are more fragrant, I will consider adjusting them.

This is a raw bean trough.

A handle that controls the opening and closing of a boiler.

These two are the data lines for temperature detection.

The new version is equipped with LED lights.

It is also the new version of the four stoves.

Here, there is still room for improvement in the details of workmanship.

Finally received the cooling fan, this is a strong power, I want to replace it with the exhaust fan. But the size doesn't fit.

This is how I cooled the beans before there was no cooling fan.

Finally, a new converter came.

After putting it on, it can finally start working normally. Do not want to make a hole in the wall to make a double screen, can only 2B with two computers a monitoring, a record. It's more convenient to have a double screen when you have a chance.

Finally can see the baking curve, moved me, finally put some beans to everyone, it is not a good bean, I use it for practice.

Summary:

Forgot to go to ID again, take the time to make up. It happens to be the Spring Festival before and after receiving the machine. We all know that we are busy with all kinds of food and drink. I also take time out to test machines, baking and so on. The photos taken are also very messy, taken at different times. At present, it has not fully entered the state, the pressure reducing valve should be changed first. After that, there is an exhaust fan, and the gas is connected to the central gas supply. At present, gas cylinders are used because it is too late to change. How to say, there are still limitations at home, such as exhaust cooling pipe can not go very good, I hope it will be much better with hard pipe. Leave some regrets. I hope you can do it all at once when you enter the new machine next time.

Let's talk about this machine, in fact, in the end, instead of trying to save time and buy mature machines such as Nissan or Taiwan, they have been made in China, not because they can't afford it, but because of the price and function. After I saw this machine, my feeling about the domestic roaster was bright in front of my eyes, because unlike other domestic baking manufacturers, they built machines just for the sake of making machines. But San Douke added some innovations, or what I call gimmicks, to build the roaster, including shaftless inner pots, adjustable boilers, and industrial-grade data output solutions. I don't want to be suspected of helping to sell advertisements here. If you are interested, you can understand it on Taobao. However, there is an obvious gap between the feeling of actual use and the effect of publicity, some functions are flashy, and some places are still not in place. Generally speaking, in terms of price, workmanship and function, this machine is moderate or good.
