Bjni Technology

“Bjni” mineral water bottling technology meets the basic requirements of hygiene for bottling and consists of the following steps:

  • mineral water extraction from the well and carbon filtering,
  • mineral water transportation from the spring to the plant through a pipeline,
  • water storage and decantation,
  • water processing (filtration,  cooling, carbon dioxide enrichment),
  • water container washing/rinsing,
  • bottling,
  • cap sealing,
  • defect elimination,
  • coding,
  • labeling,
  • packing,
  • warehousing,
  • water quality control in laboratory during the whole technological process.

It should be noted that the pipeline and the water storage containers are made of stainless metal, and regularly undergo sanitary treatment. The water filtration mechanisms are the best products of the German major company “Pall Corporation”. Before bottling the filtered mineral water is enriched with pre-filtered and purified carbon dioxide obtained from the natural carbon dioxide mine. Bottling is done in properly washed and rinsed glass containers or rinsed polyethylene terephthalate (PET) bottles. The cleaning of glass bottles is done with 1-4% sodium hydroxide solution; the rinsing is done in multiple steps with final rinsing with 1-5 mg/l hydrogen peroxide solution and purified water. PET bottles are blown directly during the manufacturing process. Rinsing is done with hydrogen peroxide of 1-5 mg/l solution. Bottles are automatically transferred from washing/rinsing machine to the bottling machine. Bottling is done in automatic pouring cameras by isobar method. Cap sealing is also done with automatic system, under the permanent control of operators of production and quality control. Cap sealing machine is placed in bottling machine - this guarantees bottled product sterility during the period of shelf-life. Sealed bottles are coded by the coding laser machine. Manufacturing date, time and batch are marked on every bottle. Finished product is labeled by attractively designed labels glued on the cylindrical part of the bottle. After labeling the product is packed with thermal shrink film by the automatic packing machine. Packed products are stored in special dry and protected from direct sunlight warehouse premises with 5-20°C temperature, on pedestals that are buffering the bottles from contacts with the walls or the floor. Bottled mineral water is recommended to keep in a dark and cold place, in horizontal position and away from direct sunlight. Shelf-life period of product is 12 months from the manufacturing date. During this period insignificant amount of sediment mineral salts may occur, which is fully acceptable.
