The trend toward healthier water is being driven by consumer demand for less sugar, as well as reports of lead contamination and other scary news about city water supplies that have led consumers to pay more attention to the safety of their water sources.
High-quality bottled water
Mineral water is uncontaminated underground spring water that naturally gushes out from deep underground or is artificially exposed; it contains a certain amount of minerals, trace elements or carbon dioxide gas; under normal circumstances, its chemical, flow, water temperature and other dynamics are relatively stable within the natural fluctuation range. From this concept, it can be seen that natural drinking mineral water is a kind of earth resource formed under special natural geological conditions. Because it is pollution-free and has a long growth cycle, it is an ideal drink in nature that is natural, nutritious, hygienic and safe.
Factors that affect the quality of mineral water
- The selection of water source is the basis of process control
1) The overall structure of mineral water quality is excellent. Not only should we look at the content of trace elements in mineral water, but we should also pay attention to the content of macro elements in mineral water.
2) Environmental control around the water source is very important. When building a factory, a protection zone must be established first. First, residential areas must be eliminated within the water source protection zone. Second, any type of production factory must be eliminated to prevent the environment of the protection zone from being damaged.
- Solutions to green algae in bottled mineral water
1) Use ozone sterilization. Long-term production experiments have shown that when the concentration is 0.4-0.6mg/L, combined with an oxidation tower equivalent to the water treatment volume, green algae spores can be effectively killed. At the same time, ozone is dissolved in water and then filled into the bottle and sealed, which can also play a certain post-sterilization role. Ozone can be completely decomposed within two to three days and will not affect water quality and drinking.
2) Install ultraviolet lamps in the water treatment workshop. When not in production, ultraviolet lamps can be used to irradiate the production environment to assist in purification.
- The role of equipment selection in process control
The purpose of mineral water treatment equipment is mainly to remove impurities, colloidal particles and bacteria in mineral water. Therefore, mineral water treatment is easy to simplify in the process arrangement. Commonly used equipment includes: multi-media filter, precision filter, microporous filter, sterilization device, but due to the different quality of mineral water, when selecting equipment, it is necessary to configure it according to the characteristics of your own mineral water. It should be noted that the water pump, pipeline and water storage tank should be made of non-toxic, odorless, corrosion-resistant, easy to clean and non-leakage materials, preferably stainless steel.
- The selection of filling equipment includes all equipment from bottle sorting to boxing. Here we only analyze the main equipment selected.
1) Selection of bottle washing machine. The bottle rinsing process is an important link to ensure the cleanliness of the bottle cavity. The pressure of the rinse water, the rinse time, the dripping time after the rinse, and the discharge method of the rinse water are important parameters for the washer to meet the process requirements.
2) Selection of filling machine. How to fill the mineral water into the bottle smoothly, instantly, accurately and without leakage is the core of this equipment. In addition, the loss during continuous operation, equipment stability and energy consumption are all important factors in the selection of filling machines.
3) Selection of capping machine. The capping machine is a key equipment to ensure product quality and yield. The capping efficiency of the unit capping head, the capping method and the adjustment range of the capping torque are the main indicators for measuring the capping machine.
The production of high-quality bottled mineral water requires not only high-quality water sources and advanced production technology, but also, like other products, requires the full coordination of people, machines, objects, materials and methods.
