Abstract

Sposób uzdatniania skroplin powstalych z procesów zatezania soków i przetworów owocowo-warzywnych w tym proszków owocowych i warzywnych wykorzystywanych na cele produkcji wody procesowej charakteryzuje sie tym, ze skropliny z wyparki po wstepnym schlodzeniu w wymienniku ciepla (1) do temperatury od 40 do 20°C korzystnie od 30 do25°C wprowadza sie na wieze desorpcyjna wypelniona pierscieniami (2) i w przeciwpradzie przepuszcza sie powietrze, przy czym stosunek strumienia przeplywu wody w stosunku do strumienia przeplywajacego powietrza wynosi od 1:12 do 1:2 korzystnie od 1:5 do 1:7 a czas poddawania skroplin procesowi desorpcji wynosi od 20 do 480 s, po czym skropliny za pomoca pompy RO (3) pod cisnieniem od 8 do 22 barów kieruje sie jako nadawe na instalacje odwróconej osmozy RO (4) skad permeat w ilosci powyzej 75% nadawy przetlaczany jest na kolumne z sorbentem jonowymiennym (5) stanowiacym makroporowata zywice na bazie polistyrenu i poliakrylu sieciowanego dwuwinylobenzenem z predkoscia liniowa do 30 m/h po czym jako woda procesowa wplywa do zbiornika retencyjnego (6) a koncentrat w ilosci do 25% nadawy kierowany jest do transportu hydraulicznego owoców i warzyw. Sorbent jonowymienny stanowiacy makroporowata zywice na bazie polistyrenu i poliakrylu sieciowanego dwuwinylobenzenem po calkowitym podstawieniu jest utylizowany w miejscach do tego przeznaczonych lub tez jest regenerowany za pomoca od 1 do 4% roztworu wodorotlenku sodu lub potasu. W przypadku wykorzystania wody procesowej na cele chlodnicze stabilizuje sie ja mikrobiologicznie poprzez dodatek biocydu stanowiacego mieszanine zwiazków 5-chloro-2-metylo-2H-izotiazol-3-onu i 2-metylo-2H-izotiazol-3-onu podawanych w stosunku 2:1 w ilosci od 0,05 do 1mg/l.The method of treating condensate resulting from the processes of concentrating juices and fruit and vegetable preserves, including fruit and vegetable powders used for the production of process water, is characterized by the fact that condensate from the evaporator after initial cooling in a heat exchanger (1) to a temperature of 40 to 20 ° C preferably from 30 to 25 ° C is introduced onto the desorption tower filled with rings (2) and air is passed through the counter-current, the ratio of the water flow stream to the air flow being from 1:12 to 1: 2 preferably from 1: 5 to 1 : 7 and the time of condensation process for desorption is from 20 to 480 s, after which the condensate by means of the RO pump (3) under pressure from 8 to 22 bar is sent as feed to the RO osmosis system RO (4) with permeate in excess of 75 % of the feed is transferred to a column with ion exchange sorbent (5) constituting a macroporous resin based on polystyrene and polyvinyl cross-linked divinylbenzene with a linear speed of up to 30 m / h, then as process water it flows into the retention tank (6) and the concentrate in the amount of up to 25% of the feed is directed to the hydraulic transport of fruit and vegetables. The ion exchange sorbent, which is a macroporous resin based on polystyrene and polyvinyl crosslinked with divinylbenzene, after complete substitution is utilized in designated places or it is regenerated with a solution of 1 to 4% sodium or potassium hydroxide. In the case of using process water for cooling purposes, it is microbiologically stabilized by the addition of a biocide which is a mixture of 5-chloro-2-methyl-2H-isothiazol-3-one and 2-methyl-2H-isothiazol-3-one compounds in a ratio of 2: 1 in an amount of 0.05 to 1mg / l.
