APPARATUS FOR THE PRODUCTION OF BACTERIALLY SYNTHESIZED CELLULOSE OR CELLULOSE-CONTAINING PLANAR MATERIAL

摘要

The invention relates to an apparatus for producing bacterially synthesized cellulose or cellulose-containing planar material, comprising a tub-type reaction vessel for holding a nutrient solution, and means for feeding nutrient solution and controlling the temperature of the reaction vessel and for supplying oxygen. According to the invention, the reaction vessel includes an elongate tub member that has a first and a second end. An inlet for a rich nutrient solution is provided at the first end, while an outlet for a weak nutrient solution is provided at the second, opposite end. Furthermore, an inclined slide for the planar material that is to be withdrawn is formed at the second end of the tub member. A withdrawing and conveying module which is located outside the second end of the tub member accommodates at least one motor-driven belt and a rinsing and cleaning tub for the withdrawn planar material. Preferably, the at least one inlet for the rich nutrient solution is disposed below the filling level of the nutrient solution in the tub member.
