The oven can be used if you are not afraid of smoke in the kitchen world maker of smoke in the kitchen. If you only want toaster, but it does not smoke mega much. If you would rather grates outside, or have more control over toasting. So I can tell how I have done.
I bought a popcorn machine. It can actually be adjusted quite easily, so it can be used as a coffee roaster. There are many who toaster in a popcorn machine. The clerk Coffee Mecca told me that he also used a. It also works on the same principle as the popular I-Roast, which costs around 2000kr.
A popcorn machine, which is based on hot air, that is to say it consists of a blower and a heater is actually excellent for roasting coffee world maker on. It also makes it easy to roast out on the balcony, garage, where smoke is not a problem. The temperature can be a challenge for the winter, but it's there for advice. Now it is summer so we take later.
Just be sure that the slats where the hot air coming into the popcorn machine sits in the side, and not at the bottom, otherwise there can be residues from the coffee down to the heating element and catch fire. When using a popcorn machine for toasting coffee on, then you have to change it a little bit for it to be warmer. This means that the plastic can melt and there is if you roast the beans too long risk of going to fire. So leave it never sight, now you advareret.
I have bought a Severin popcorn machine for 200kr. If you want to do it cheaper then look on a pocket market. The first engravings were not good, since the temperature did not go above 170 gC. The reason for this is a relay that sits inside it which cuts out. I have therefore opened it and bypass the relay with a wire. Be aware that you can not solder one wire as it becomes so hot that the solder to melt again during use. I just took a cord and twisted around on both sides of the relay. This is not something that stops the heat supply. It lets you get up high enough in temperature to roast coffee beans,
Now I can take coffee roaster with out onto the balcony, and avoid smoke in the kitchen. It provides most times really good coffee. Better world maker than the whole beans from the supermarket. Professionally roasted beans, it is not. I have not enough control over the process, since I can only control the timing where I stop toasting and cools them down. The temperature on the balcony, and especially on the fan makes a big difference in how long it takes to roast. I have therefore further plans on changing the toaster so I can both control the fan speed and heater.
Just one thing. Once you have roasted, then wait for about One day before the beans are degassed world maker and is ready for use. Beans develops CO2 in the period following and many recommend putting them in the coffee items with a valve in. However, I have not experienced any problems getting them in a freezer bag, and get a clip on, and then placing them in the refrigerator until needed.
When toaster will follow two phenomena happens world maker when you roaster. The first crack and second crack. Just like popcorn, so break coffee beans also with a popping sound when they are warmed up. First crack happening around 200gC, later in toasting comes a knock more. Typically stop toasting between 1st and 2nd crack.
