TH697B - A continuous alcohol fermentation process using fixed yeast - Google Patents

Abstract

The alcohol fermentation process continues with yeast. For the production of alcohol, it is carried out by continuously passing a carbohydrate-containing liquid substrate into a container filled with a thin film. Which has frozen yeast The surface of the thin film part extends in the direction of It flows inside the container creating a long, parallel channel, while the thin film is 10 to 65% of the container volume. The thickness of 0.1 to 3 mm should be appropriate. The thin film was obtained by mixing the yeast-containing suspension. With light crosslinkable rechin, the mixture is then exposed to light to make the resin cross-linked by light.

Claims (7)

1. Continuous alcohol fermentation process for ethan production using a fermentation vessel in which the liquid flows in one direction, comprising the process of packing thin film parts with The thickness is from 0.1 to 3 mm and the live immobilized yeast is added to the fermentation vessel in the manner where the surface of the thin film portion extends in the direction of the fluid flow. In the container, the thin films take up 10 to 65% of the volume of the fermentation vessel. And the opposite surfaces of the lateral parts on the sides of such thin films are somewhat parallel. And away from each other to form a parallel channel in the middle The funnel extends in the direction of the fluid flow and is parallel to the surface of the thin film. The aforementioned thin films consist of an important part. The living yeast is immobilized in a resin carrier formed by optical crosslinking. Which are organic substances and which form a thin film, the thin film was prepared by Mixing of aqueous yeast suspension with light cross-linked resin The resulting mixture is then irradiated with a wavelength of 150 to 60000 A to make the resin cross-linked by light. Such yeast can ferment a liquid that is A carbohydrate-containing substrate, and which can be obtained to form a fermented liquid containing ethanol by means of a carbohydrate-containing substrate liquid, and which The fermentation flows through the fermentation container. And through such a channel in the fluid flow direction so that the liquid substrate is parallel and in contact with the surface of the said thin film under conditions and for a period of time that the liquid substrate Titrate is fermented into a fermented liquid that contains ethanol. And to allow impurities and carbon dioxide from fermentation to flow with the liquid in the direction of Flow of that liquid Removing the fermented liquid from the removal opening and the removal of ethanol from the fermented liquid 2. Process according to claim 1, where the thin film portion occupies 20 to 6% of the volume of the fermentation vessel. 3. Process according to claim 1, where the thin films are a number of films that are parallel and transverse apart, are placed in the fermentation vessel. 4. Process according to claim 1, where the film section is a number of tubes that are parallel to each other. Have the same center and open ends Contained in the above fermentation container 5. Process according to claim 1, in which the optical cross-linked resin is selected from the group containing unsaturated polyester. Unsaturated and non-ionic acrylic resin Unsaturated and anion-carrying acrylic resin, unsaturated acrylic resin holds anion. Unsaturated polyvinyl resin, unsaturated cellulose Unsaturated polyamide Unsaturated epoxy resin with an acid value of 40-200. 6. Process according to claim 1, where such optical resins cross-linked It is a hydrophilic type unsaturated resin. It has an average molecular weight of 300 to 80000, and two or more photometric unsaturated rhinoceroses in one molecule. 7. Process according to claim 1, where the light cross-linked resin It is a mixture of urethane esterate pre-polymers prepared from polyethylene glycol isoforon diisocyanate and 2-hydroxyl. C-ethyl methacrylate And stimulants to the light
