Product description
Functions
Designed to improve the “deficient” dry-charging process, making it more efficient, especially for the negative plates of lead-acid batteries. More traditional methods, such as soaking acetic acid, are no longer necessary. It can also reduce nonessential manpower, and help improve both quality and efficiency.

Machine operation
The negative plates are taken out of the forming tank and put on the drying machine’s stainless steel basket. The operator controls the electric crane, submerging the stand in water several times to clean the plates so that they approach neutrality, and then proceeds with the drying. After cleaning them, the electric crane hangs out the plate basket, and then puts them into the drying chamber of the drying machine. Once the machine starts, the plates can be dried directly. It is suggested that the user provides an electric crane which can bear over 3 tons.
Product features
  • PLC electric machinery control system and air compressor system
  • High quality gas burner system for better safety, stability and efficiency
  • Gas safety device uses world-class brands like Honeywell or Yamatake to control burner safety and stabilize its performance.
  • Drying capacity: approx. 3000-5000 panels in 2.5-3 hours (the lesser the panel quantity, the shorter the drying time).
  • The drying chamber can load 4 trays of stainless steel baskets; drying degree and quality depend on the basket quantity.
  • After drying, the water content of the plates shall be less than 0.1%, and the lead oxidation (PbO) increase rate shall be less than 1%.
  • BIGO-10 can also dry positive plates (under customer request), keeping their temperature between 60 °C-80 °C to assure their quality.
  • Available in natural gas (methane) and LPG powered versions
  • Hot water cooling system:
    • Hot water discarded by this machine must be cooled in a cooling tower before returning to the drying machine for circulation.
    • The user has to provide a cooling tower with at least 10 tons/h capacity.
    • It is suggested that the circulation volume of the tower be 20 tons/h, to make sure that it will still be able to supply sufficient water if water consumption increases.
