Useful properties of melt water are described in numerous popular science publications. The proposed technology allows for an autonomous preparation and sale of melt water in devices designed for mass consumption in offices, shops, sports facilities and others. The operational principle of the device is very simple: the working tank is filled with raw water; the device automatically analyses its parameters, such as temperature, pollution, salinity, etc., and selects the appropriate mode of preparation of melt water. In the process of freezing the appliance specifies the stage where harmful impurities are separated (to form brine); they have a lower freezing point. They are dispatched into a separate tray for contaminated water. The remaining ice is free of impurities is subjected to soft, gradual defrosting, resulting in meltwater. The device has an automatic washing function, which allows for maintaining the hydraulic system clean. The proposed technology allows for water purification without the use of artificial filters and chemical additives. Technological "know-how" is based on the principle of natural water purification, as a result of freezing and thawing. The company already has an experience in the development and market entry of projects in the sphere of production of melt water. The proposed technology has the following content: 1. Complete set of intellectual property. 2. Complete set of design documentation. 3. Complete set of technical documentation for assembly operations. 4. Specification and a detailed listing of components and parts of the vending machine with prices and suppliers. 5. A set of original software. 6. Test hardware. 7. Operation and maintenance manual. 8. Equipment passport and certificate (declaration of conformity for the customs union ("EAC" mark)) for the vending machine. 9. A working prototype of the vending machine, after the open field trials and laboratory studies. 10. An industrial prototype of the vending machine, after closed field trials and laboratory studies. 11. Official reports and conclusions on the results of laboratory tests. 12. Marketing and promotional video presentation. The company is ready to provide further assistance for the implementation of the project into production, staff training and the transfer of all rights to the technology.
