<p>The invention relates to technical systems for purifying water using a recrystallization method and for selling portions of meltwater to the public, and can be used in the food industry and in trade. The technical result is the creation of a high-performance, compact combined mini-facility and vending machine for the purification and sale of portions of meltwater. The combined mini-facility and vending machine contains a housing (1), in which are disposed, interconnected with one another, an electronic control unit (2), a water purification system (3) having an end-product dosage dispenser (4) connected to a source-water feed pipe (5), and a payment acceptance device (6). The water purification system (3) includes a plurality of thermostated heat-exchange containers having cooling thermoelements (15) and heating thermoelements (16) positioned on the surface of the walls thereof, a thermostated collecting container (10) for purified water, a means (11) for filtering and feeding source-water for purification, a means (12) for discharging a liquid concentrate of organic and inorganic impurities, a means (19) for feeding purified water to packaging containers, and a means (20) for discharging unused purified water, which are connected to the collecting container (10). Each of the heat-exchange containers (7, 8) is made of a thermally-conductive material and is in the form of a rectangular parallelepiped having a flat slotted inner cavity (21).</p> |
