The beer bottle spray rinse method is essential to ensure thorough internal cleaning. The injection pressure and jet size are critical factors. The jet must be fine enough to reach all areas of the bottle's bottom simultaneously, while the amount of liquid sprayed should be moderate—too much can cause air embolism. Typically, the injection pressure should be maintained between 0.20 and 0.25 MPa. However, this method has several drawbacks. First, the basic solution lacks buffers, penetrants, and scale inhibitors, leading to high total alkalinity. At washing temperatures, the label paper can easily corrode and disintegrate, causing blockages in the spray nozzles and scaling on the pipes. Second, strong alkalis can erode glass bottles, resulting in a less shiny appearance after cleaning. Third, the absence of colloidal agents like hair or phosphate reduces its effectiveness in breaking down mineral oil, potentially leaving the residual liquid in the cleaned bottles with a high pH.
In the beer industry, bottle washing agents are generally categorized into three types. The first type uses only sodium hydroxide (NaOH) as the cleaning agent. The second type consists of a mixed powder containing solid detergents, NaOH, sodium carbonate, phosphates, and other additives. The third type employs liquid or solid alkali as the main component, combined with high-performance additives. Comparing these options, the compound solid washing agent offers lower total alkalinity, reduced damage to label paper, easier mechanical descaling, and stronger overall cleaning performance. Bottles washed with this agent tend to be bright, clean, and free from scale, also offering some protection to the equipment. However, it comes with higher costs, more foam during the process, and contains phosphorus, which does not align with current phosphorus-free washing standards. Despite these limitations, it remains a popular choice due to its effectiveness and reliability.
