Product Description Equipment descriptionTimber coking equipment which is designed by Antai machinery co., LTD can effectively improve the dimensional stability and the anticorrosion property of timbers. Without any chemicals, the process of coking which have no harm to human and environment can make the wood antique color. This equipment solve the relation between coking process parameters and the effect of carbonization by the control of the carbonization temperature and holding time. The process parameters of the equipment play a decisive role to the performance of the coking wood. Our company designed and developed the automatic drying control programs by measuring and analyzing the color, quality, hydroscopicity, wet swelling property, mechanical property and chemical components of the coking wood under different conditions of carbonization. And the rationality of the equipment has reached the world advanced level. Carbonized craft of timbers1. Carbonized temperature and holding time directly affect the wood carbonized effect. Different kinds of timber have different crafts because of the difference properties of the woods. 2. With the increase of carbonized temperature and holding time, the color of wood darker and the uniformity of the color increased, the depth of the carbonization deeper, the hydroscopicity and wet swelling decreased, the dimensional stability increased, the mechanical property decreased, so the carbonized timber is not recommended as load bearing material 3. With the increase of carbonized temperature and holding time, the dimensional stability of the carbonized wood increased obviously because of the number of C=O and -CH3 reduced. The quality of wood will be changed after carbonization and the hemicelluloses will be degraded in the process of heat treatment. Tank type anaerobic carbonization process equipment and features1. Low-pressure superheated steam vacuum carbonization process Mainly consists of three stages: First, vacuum heating drying stage l Second, the vacuum boost carbonization stage l Third, relief cooling stage 2. Feature PLC automatic computer control system to ensure accurate and reliable control, add medium circulation device to ensure uniform heat treatment, carbonization treated wood fineness uniform, no smell. According carbonization needs to maintain an oxygen-free vacuum carbonized in the carbonization process, the temperature is between 160 ~ 230 oC adjustable. Six sets of security system to ensure safe operation of equipment. Stainless steel tank, corrosion resistance, durability, processing and flexible. Suitable for mass production of high-end wood processing enterprises. High temperature depth carbonized wood process:Stage 1: raise and dry stage by high temperature , with high temperaturesteam to raise 100oC, at this time ,the moisture of the wood is closed tozero ,the drying time of high temperature is up to original moisture ofwood ,and variety of trees ,and thickness of wood , if treated wood havehigh moisture ,it should be put into Kiln drying. Stage 2: heat treatment stage ,the heat treatment is under lowoxygen airtight furnace ,according to treatment requirement , after hightemperature dry ,when the temperature of furnace get 200 oC ,we canbegin to treat, the time of heat treatment is up to original moisture ofwood ,and variety of trees ,and thickness of wood Stage 3: cool and moisture mediation treatment stage ,after heat treatedwood become cool within controlled condition ,at this time use spraysystem to cool down the temperature ,then to process moisture mediationtreatment .Pay more attention at this time ,after heat treatment wood is inhigh temperature stage , and have big temperature difference withoutside .it will make wood crack ,this treated time is related to variety oftrees and treated time.Technology processes: dry in the drying kiln with normal temperature---- high temperature steam dry in the carbonization tank----- high temperature heat treatment in the carbonization tank------spray cooling-----Pressure and cooling the tank---- the environment stable balance-----Finish Advantages of the equipment1. Full automatic control by computer2. The frame of the equipment is made of stainless steel to prevent corrosion.3. High precision and better effect of treatment.4. Easy to operate, energy saving and environmental protection. The main configuration Introduction1. The ways to open the door: Open door manually, open the door by electricity, open the door by hydraulic. Advanced open door method ,only one young girl can open the door easily. 2. The sealing way: With the gas-filled silica gel seal ring, the air filled style sealing effect of the equipment is significantly better than others'. And the life of the equipment is more than one year.3. Safety interlocking methods of the door of the tank: Automatic pressure safety interlocking method and Manual safety interlocking method, it solved the safety problem of wrong operation.4. Vacuum control: After setting a vacuum table, vacuum reaches a predetermined value, close the valve to stop the vacuum.5. Condenser: steam condensate systems, automatic water system6. Pressure Control: Using two pressure gauges, pressure tank through a valve control, reaches a predetermined pressure value after closing the valve and stop the boost and maintain pressure after a certain time relief. Design 2 flange open safety valves, after reaching the design pressure relief valve automatically opens, ensure the safety of the tank.7. Load: Two rail tank, using the 9th road rail. Good bearing, long life, safe and convenient.FAQ
