METHOD FOR PRODUCTION OF NATURAL WATER AND CONCENTRATED JUICE Russian patent published in 2011 - IPC A23L2/08 

FIELD: food industry.

SUBSTANCE: invention is related to food industry, in particular - to technological processes for production of natural water and concentrated juices from fruit-and-berry raw material and may be used for development of functional products and beverages for children, dietary and special alimentation, production of reconstituted juice in wine making. The method is characterisation is as follows: directly squeezed juice is distilled under working pressure 10-1 Pa and at a temperature up to 50°C, the vapour is condensed and chilled to produce the distillate represented by natural water. The distillate is collected into the main sump and heating is discontinued in the process of evaporation when the distillate delivery rate decreases. Concentrated juice is discharged from the evaporator into the receptacle vessel and the following cycle is implemented. In this cycle the distillate is collected into the additional sump. Water is delivered into the receptacle vessel and the main sump for pressure therein to be increased to reach the atmospheric pressure level. Concentrated juice and natural water are discharged from the receptacle vessel and the main sump accordingly. Then juice is delivered into the feed vessel from the directly squeezed juice vessel; one reduces pressure in the feed vessel, the receptacle vessel and the main sump to the working pressure level and implements. The following distillation cycle. In this cycle directly squeezed juice is heated in the feed vessel to the working temperature of juice in the evaporator.

EFFECT: invention allows to reduce duration of the process of concentrated juice and natural water production.
