Model ST series Full automatic outside Brushing Machine is affiliated production facility for three&five gallons barrel packing production. ( For 5 gallons: Barrels-barrels are able to brush that particular mineral water suitable for the production, effectively removing the barrels from Mineral internal (mineralization) of water-induced sedimentation and algae material. Barrels in the bottom of the plane, the external and internal-off several parts, significantly enhanced the effectiveness of the cleansing, greater reduction of manual clearing secondary pollution and reduced operating personnel labor intensity. The overall production of a high quality stainless steel, corrosion resistant, Yiqingxian. Siemens major electrical originals are used, Omron products, the introduction of the original import gas Lu AIRTAC products. The construction of the machine is rather compact, the work efficiency is rather high, it is stable and reliable, its automation level is rather high, It is affiliated 3-in-1 equipment integrating machinery, electrical appliance and pneumatic parts for full automatic barrel packing production line. After brushing, it needs disinfection washing and cleaning with pressure of more than 0.2 MPA for more than three seconds.
