◆ dry technology is mature
◆ dry quality has assure (accord with Euramerican area quality to ask)
◆ moving cost is low (be like deal: 30 yuan, 50 yuan / M3)
◆ operation is simple, convenient -- " goofy " type
◆ lumber color is controallable
◆ is defatted, become angry, coloring kills the functional ◆ such as bug, sterilization, modified to need vapour heat addition
Furnace of ◆ investment moderate enrages ◆ of indirect dryer need not vapour
◆ equipment is simple
◆ investment is little
◆ dry technology is immature
◆ cannot accurate control temperature, humidity
◆ cannot eliminate lumber (grow, dry, leftover) stress
◆ lumber is easy happen be out of shape, craze
◆ color is deepened extremely easily
◆ is put in fire hidden trouble
◆ is put in factitious error phenomenon
Every kiln needs ◆ a boiler is brought about it is mature to increase dry technology of ◆ of vacuum dryer artificially
◆ dry cycle is short
◆ does not have dry blemish
◆ moving cost is low
◆ does not suffer field to limit ◆ equipment price too tall
◆ uses ◆ of of dryer of miniature production dehumidify only need not steam boiler
Power consumption of ◆ of ◆ free from contamination is too big ◆ equipment maintains, upkeep costs is high
Low ◆ of ◆ dry temperature productivity is small
◆ dry cycle grows ◆ to invest the sources of energy of ◆ of of dryer of moderate solar energy to abound
◆ does not have environmental pollution
◆ runs cost low ◆ to accept natural condition restriction
◆ installation cost is high
◆ part is easy damaged, dry rate of ◆ of of dryer of upkeep costs tall microwave is rapid
◆ does not have craze, be out of shape, maintain power consumption of ◆ of lumber instinctive quality great work ◆ needs special conserve staff
Tall ◆ of complex, investment uses ◆ device at miniature production only
Tall ◆ destroys ◆ facility depreciation cost equipment of ◆ of of dryer of infrared ray of lumber nature quality of a material is simple, investment is little
◆ heats rate is rapid
◆ realizes flow operation easily, manufacturing efficiency is tall
◆ suits thin plate to produce ◆ of of hot pressing dryer only dry rate is rapid
Surface of ◆ dry backboard is flat
The stability after ◆ is dry is good
◆ enhances reduced scale of exterior hardness ◆ serious
◆ surface color is deepened pale, and hair is fragile
◆ equipment complex, investment bigger, moving cost is high
