1. Vacuum System
Vacuum system mainly consists of oil ring vacuum pump and roots vacuum booster, can achieve 10 mbar absolute pressure. Under the state of higher vacuum, vapor in the leather can be largely pumped out in a shorter time, so the machine greatly promotes the productivity.
2. Heating System (Patent No. 201120048545.1)
1) High efficient hot water pump: world famous brand, follow international energy-efficiency standards.
2) Hot water channel : special flow channel design.
3) High efficiency in heat conduction and uniform heating, reduces vacuum time.
3. Vacuum Releasing System (Patent No. 201220269239.5)
Unique Vacuum releasing system employs tailor-made mechanisms to prevent condensate flowing back to working plate to pollute the leather.
4. Safety System (Patent No. 2010200004993)
1) Hydraulic lock and balance valve :avoid descent of working plates.
2) Mechanical safety device : Air cylinder drive safety block to prevent the descent of its upper plates.
3) Emergency stop, working plate tracking device.
4) Electro sensitive protective device : when machine in movement, worker can not approach to machine, when worker is operating, working plate can not move.
5. Condensating System (Patent No. 2010200004989)
1) Double staged condenser in Vacuum system.
Primary condenser : each working plate is equipped with stainless steel condensers inside its front and back sides.
Second condenser : at upstream of roots vacuum booster.
2) Such equipments of condensers speed up the condensation of vapor, enhance the efficiency of the roots vacuum booster and vacuum pump, increase the suction capacity and heighten the vacuum degree.
3) Others: cooler for hydraulic oil, cooler for vacuum pump oil.
6. Working Plate
Smooth surface, sandblasting surface and semi-matt surface also as customer option.
7. Advantages
1) High quality : using this low temperature dryer machine, the leather quality can be raised substantially, because the leather after drying, its grain face highness is flatten and uniform, it’s felt soft and plump.
2) High leather-obtain rate : while vacuum drying with low temperature, only sucks steam out of leather , and the grease oil can not be lost, the leather can be fully spread and not stringer, and to keep leather thickness not changing.
3) High capacity: due to the working table surface temperature can be lower than 45℃,the capacity is 15%-25% higher than other same machine,
