Cheap bean roasting equipment, roasting coffee beans in an oven

There are still a few jin of coffee and raw beans on my hands. Recently, it was hot and the range hood was broken. It was so painful to fry beans in a frying pan that I had to put in a new set of bean baking equipment.

The finished product baked first, using Manning's raw beans, a cage of beans baked in two stages, one is the first explosion of light baking, the other is the second explosion of deep baking.

The taste of light-baked beans is already very rich, and generally baked to this level is basically enough.

The deep-baked beans are a little too much and produce a lot of oil. basically, Starbucks beans are baked at this level, peeling off all the flavor, mainly the bitterness of the coffee.

Beat into powder quickly, the newly baked beans are not suitable to drink right away, and should be stored for another day to let it mature, otherwise it will have a very strong smell of fireworks, so it is not suitable to store in large sealed bottles. Bags or jars with one-way valves are the most appropriate.

The baking process, first of all, is called beans, this set of baking equipment capacity is limited, it is difficult to bake evenly.

150 grams, baked out about 100 grams, two cups a day, I can drink for a week, basically in line with the fresh-keeping standards.

Beans on the grill, this set of equipment, worth 26 yuan, including freight 31 yuan.

The iron bar in the middle of the cage turned out to be a fork for roasting chicken. Remove the fork and install it on the cage. In addition to roasting coffee beans, it is usually used for roasting peanuts, melon seeds, ginkgo, or stuffing bare Padan wood into it. It is very convenient for drying or even roasting.

It can also be used to dry dried mushrooms, fungus, dried shrimp and other practical information, which is very convenient.

The theoretical process of roasting coffee:

Preheat to 150 degrees

Put in the coffee beans

Dehydration for 10 minutes

Heat up to 250 degrees

There is an explosion about 180-190 degrees.

There are two explosions at 220 degrees.

Arrange the bean production time according to your needs.

The actual process of roasting coffee:

Preheat to 150 degrees

Put in the coffee beans

Turn on the switch directly to max

The big paper explodes in 15 minutes and 2 in 25 minutes.

After the small oven heats up to 150C, the temperature will become very slow. The marked temperature of 250C can't reach it at all. The highest temperature of my oven is only 220C, which is also the reason why I often failed to make bread before. Later, I all switched to max but succeeded several times, so those who play with the oven must have an oven thermometer and something worth 30 yuan. I received the goods in the morning when I tested the cage, and it just came in handy.

The specific process of baking.

The rotation speed of the baking cage is much slower than that of professional and amateur direct fire roasters with dozens of revolutions per minute. It has only 4 revolutions per minute. Yes, it rotates every 15 seconds, but because the roasting cage is ten times more away from the heating tube than the direct fire roaster, the roasting is quite uniform, but the heating is too slow.

The sound of the first explosion and the second explosion of beans is not like the thunderbolt of Pala, but there is a sound at intervals of a few seconds, and then another sound after a few seconds, do not think that this is not a good time, it is actually OK, the first time I was waiting there, the result baked out a beautiful cage of pure carbon balls.

The thermometer hanging on the stove points to 180 degrees (small print in the circle), which is the sound of an explosion, which took more than ten seconds to explode three times.
