Method of obtaining clean drinking water from dehydrated biological products and device for dehydrating such products

Abstract

The subject of the application is a method for obtaining clean drinking water from dehydrated biological products and a device for dewatering such products. The subject of the application is a method for obtaining clean drinking water from dehydrated biological products, which accompanies the dewatering process of these products, carried out in a hermetic dewatering chamber isolated from the ambient atmosphere. This process runs parallel to a process during which the dried products placed on drying trays arranged on at least one rack with shelves equipped with heating surfaces are tightly sealed inside the hermetic dewatering chamber. The products have already undergone an initial phase of exposure to a gaseous medium in the form of nitrogen at a temperature of 30°C to 45°C and a pressure of 1.1 to 1.4 Pa inside the dewatering chamber. The actual dewatering phase begins, initiated by the activation of all components of the device.including the setting and control system, which automatically regulates all parameters of the dewatering process, such as temperature, humidity and the appropriate pressure inside the dewatering chamber, after which the raw material - via the ventilation and heating systems - is subjected to two processes simultaneously, i.e. the process of blowing with a gaseous agent that flows through the biological product bed under overpressure and at a set temperature from 30° to 45°C and the desorption drying process caused by the heating surfaces of the shelves, which consists in heating the product to a temperature of 40 - 45°C by the heat released from the heating system, and the water vapor generated during the product dewatering process, originating from / released from these dewatered products, is continuously removed from the dewatering chamber through the upper opening, escapes through the outlet pipe and passes through the flow (air) channel to the condenser (condenser),located outside, i.e. outside the dewatering chamber, and the condensate is directed to a special tank, also located outside, i.e. outside the dewatering chamber. According to the application, the process of obtaining clean drinking water is carried out outside the dewatering chamber (1), and it takes place in several successive stages, in which: warm water vapor coming from the dewatered products, continuously escaping through the upper opening of the dewatering chamber (1), goes to the outlet pipe (13), which is part of the PP flow channel, located outside, i.e. outside the dewatering chamber (1), flows through wire disinfection grids placed in this PP channel, then the water vapor flows towards the condenser made of acid-resistant steel, which is cooled by a refrigeration unit (18),whereby, as a result of the cooling of the condenser, a "dew point" occurs at the interface between the warm gases leaving the dehydration chamber (1) and the condenser (condenser), at which - at the condenser cooling temperature in the range of +5°C to +15°C, the gas condensation process begins, water vapour condenses on densely arranged lamellas made of acid-resistant steel, located inside the condenser, then the fans (4) pump the water vapour, and the condensate resulting from the condensation of water vapour is directed under sterile conditions from the condenser to the drain pan (21), the condensate flows into the flow conduit (i.e. pipes or hose) and through it, under sterile conditions, flows into a special water storage tank (16).,
