Genom föreliggande uppfinning åstadkommes en snabb hydrolys under helt driftsäkra betingelser och under iakttagande av arbetsmilj öproblemen.The present invention provides rapid hydrolysis under completely reliable conditions and while observing the working environment problems.
Uppflnningen kommer nedan att närmare beskrivas med hänvisning till ett föredraget utföringsexempel, utan att dock vara begränsad därtill, och med hänvisning till bifogade ritning, vari FIG. l visar en blandningsanordning enligt uppfinning i en schematisk sidovy.The invention will be described in more detail below with reference to a preferred embodiment, without being limited thereto, and with reference to the accompanying drawing, in which FIG. 1 shows a mixing device according to the invention in a schematic side view.
Med l betecknas en matarskruv, som transporterar mjöl av vete, råg, kom, havre, majs, ris, sorghum och/eller annan cerealieråvara från en silo (ej visad) till en doserare 2 omfattande en fläkt 3, en vibrator 4 och en mjuk anslutning 5 till en tillförselstuds 6 i ett reaktionskärl 7.Denoted by 1 is a feed screw which transports flour of wheat, rye, grain, oats, maize, rice, sorghum and / or other cereal raw material from a silo (not shown) to a dispenser 2 comprising a fan 3, a vibrator 4 and a soft connection 5 to a supply spout 6 in a reaction vessel 7.
Reaktionskärlet 7 innehåller en omrörare 8 som styrs av en motor (visad schematiskt) placerad över reaktionskärlet 7. Ett tilltörselrör 9 för vatten är placerat på reaktoms 7 nedre del, medan ett tillförselrör lO för enzymlösning är placerat i reaktoms 7 övre del. I reaktoms §1 f. 10 15 20 25 30 512 559i 3 7 botten föreligger ett utlopp 11 för uttag av i reaktorn 7 framställd reaktionsblandning.The reaction vessel 7 contains a stirrer 8 which is controlled by a motor (shown schematically) placed over the reaction vessel 7. A supply pipe 9 for water is placed on the lower part of the reactor 7, while a supply pipe 10 for enzyme solution is placed on the upper part of the reactor 7. In the bottom of the reactor §1 f. 10 15 20 25 30 512 559i 3 7 there is an outlet 11 for withdrawing the reaction mixture produced in the reactor 7.
Omröraren 8 i reaktionskärlet 7 omfattar ett bladpaket 12 för blandning och en propeller 13 vid utloppet 11, vilken propeller 13 omfattar vingar parallella med axeln, vilka vingar slutar strax innanför en perforerad ring genom vilken reaktionsblandningen är avsett att lämna reaktionskärlet. Ringen medför att inga väsentliga mjölklumpar kan lämna reaktionskärlet 7.The agitator 8 in the reaction vessel 7 comprises a blade package 12 for mixing and a propeller 13 at the outlet 11, which propeller 13 comprises wings parallel to the shaft, which wings end just inside a perforated ring through which the reaction mixture is intended to leave the reaction vessel. The ring means that no significant lumps of milk can leave the reaction vessel 7.
Bladpaketet 12 omfattar tre propellrar 14, av vilka de två översta är större och verkar genom att pumpa produkten nedåt intill axeln och den tredje, som är mindre, har omvänd fiinktion.The blade package 12 comprises three propellers 14, of which the top two are larger and act by pumping the product downwards next to the shaft and the third, which is smaller, has a reverse function.
Därmed åstadkommes en intensiv omrörning i den övre delen av reaktionskärlet 7 innan reaktionsblandningen kommer i närheten av utloppet. Reaktionskärlet 7 innehåller vidare i sin cylindriska del längsgående bafflar för att öka omblandningen.Thereby an intense stirring is effected in the upper part of the reaction vessel 7 before the reaction mixture comes close to the outlet. The reaction vessel 7 further contains in its cylindrical part longitudinal baffles to increase the mixing.
Blandaren är avsedd för en kontinuerlig beredning av reaktionsblandning. Härvid tillföres mjöl från silo (ej visad) genom doseraren , lämpligen med flera parallella matarskruvar 1 som arbetar med volumetrisk dosering. För att säkerställa mjöltillförseln till matarskruven 1 kontrolleras med kännare kontinuerligt att utrymmet i inloppet till doseraren 2 är fyllt. Om så inte är fallet åstadkommes nedskakning av mjöl medelst i silon anordnad vibrator. Från matarskruvens ände faller mjölet medelst kontinuerlig vibration 4 genom schaktet till reaktionskärlet 7. För att förhindra att fuktig luft kommer upp i schaktet och därmed riskera att mjölet hänger sig i schaktet blåses via en fläkt 3 med ett lågt flöde, lufi ned genom schaktet. Denna luft lämnar reaktionskärlet 7 via ett ventilationsrör (ej visat).The mixer is intended for a continuous preparation of reaction mixture. In this case, flour from the silo (not shown) is supplied through the dispenser, suitably with fl your parallel feed screws 1 which work with volumetric dosing. To ensure the flour supply to the feed screw 1, it is continuously checked with sensors that the space in the inlet to the dispenser 2 is filled. If this is not the case, shaking of flour is effected by means of a vibrator arranged in a silo. From the end of the auger, the flour falls by continuous vibration 4 through the shaft to the reaction vessel 7. To prevent moist air from entering the shaft and thereby risk the flour hanging in the shaft, it is blown via a fan 3 with a low fate, lu fi down through the shaft. This air leaves the reaction vessel 7 via a ventilation pipe (not shown).
Vatten med en temperatur av 80-l00°C, lämpligen 90°C, tillíöres med reglerad mängd till reaktionskärlet 7 genom att injiceras under reaktionskärlets 7 produktnívå genom tillförselröret 9. Härigenom minimeras värme och vattenförlust via schaktventilationen, liksom med sådan vattenförlust buret enzymmaterial.Water with a temperature of 80-100 ° C, preferably 90 ° C, is supplied in a controlled amount to the reaction vessel 7 by being injected below the product level of the reaction vessel 7 through the supply pipe 9. This minimizes heat and water loss via the shaft ventilation, as well as with such water loss carried enzyme material.
En med doseringspump (ej visad) tillsats av enzymlösning sker över produktnivån i reaktionskärlet 7 via ett tillförselrör 10.An addition of enzyme solution with dosing pump (not shown) takes place above the product level in the reaction vessel 7 via a supply pipe 10.
I reaktionskärlet 7 åstadkommes därefter en intensiv omblandning som redovisats ovan, varvid gelatinisering initieras liksom stärkelsehydrolysen. Gelatinisering och fullständig hydrolys, eller hydrolys till önskad grad sker därefier i lämpligt slutreaktionskärl. Sådan ' 'lll l ll' l llllllllll ll l“"| .a iii i liíxñh 512 559 4 slutreaktion, före deaktivering av ingående enzymer, tar i föreliggande process normalt c:a 1 timme. Deaktivering sker genom uppvärmning av reaktionsprodukten till 97-98°C under 2 min.In the reaction vessel 7, an intensive mixing as described above is then effected, whereby gelatinization is initiated as well as the starch hydrolysis. Gelatinization and complete hydrolysis, or hydrolysis to the desired degree, take place in a suitable final reaction vessel. Such a '' lll l ll 'l llllllllll ll l "" | .a iii in liíxñh 512 559 4 final reaction, before deactivation of the constituent enzymes, normally takes about 1 hour in the present process. Deactivation takes place by heating the reaction product to 97- 98 ° C for 2 min.
