Use charcoal machine to carbonized charcoal carbonization furnace gradually replaced by kiln to charcoal, there are many reasons: Tuyao no tar separation device, the tar can not handle, charcoal machine - carbonization furnace is different, with tar separator, carbonized tar produced good time; Tuyao fired kiln of charcoal can not control the temperature inside the machine, charcoal carbonization furnace is different, charcoal machine - carbonization furnace configuration with a temperature display, can be observed at any time - charcoal machine in carbonization furnace temperature; kiln charcoal burning will appear rawish phenomenon, charring furnace carbonization out good quality charcoal, the surface is smooth and bright, also no rawish phenomenon; Tuyao will produce gas in the production process, carbonization furnace configuration of flue gas treatment system for flue gas treatment, can produce very good, does not produce pollution; Kiln carbonization time long, a carbonizing kiln complete need seven or eight days, the carbonization furnace is not the same, the lowest yield a set can be a ton of charcoal production and carbonization time short. Is due to the reasons, is machine made charcoal carbonization furnace is more popular than the kiln, it is also because of this, many users in charcoal usually choose the carbonization furnace, also do not use the kiln.
