straw briquette machine to produce cheap cooking fuels
Straw briquette machine is used to make maize straw, wheat straw, rice straw, barley straw, oat straw, rye straw, and other kinds of straw into fuel briquettes. It also can process peanut shell, sawdust, tree branches or leaves.
The straw briquette machine has high productivity and is easy to operate. It is a kind of environmental friendly and energy saving machine for biomass, which is very helpful to the rural areas. It can help farmers turn waste into wealth and make great profit.
The applications of straw briquettes:
The straw briquettes made by straw briquette machine have 1/30 of original straw volume, high density as 0.9-1.4m3, and 3500-5500kcal/kg heat value. So they can replace firewood, coal or liquefied gas to be used in stoves, heating furnace, hot-water boiler, industrial boiler, biomass powder plant, biomass gasification boiler, etc.| Cotton straw briquettes | Maize straw briquettes |

How to make briquettes with straw briquette machine?
-
Crush your raw straw. We all know that straw is at least 1 foot long, which is not suitable for direct briquetting. So first we need to crush it into much smaller size like several millimeters in diameter with hammer mill.
-
Dry the straw. If your straw is sundried, there is no need to use dryer. If your straw is wet, it’s advised to use a dryer to decrease its powder moisture to about 10-18%.
-
Briquetting. After crushing and drying, the straw powder is conveyed into the straw briquette machine for briquetting. GEMCO straw briquette machine is mechanical stamping type, which means it generates great pressure when operating. So when the briquettes get out from the machine, they have high density and not easy to break.
-
Cooling. After briquetting, the briquettes may have high temperature, so you need to cool them to room temperature.
