Abstract
A biochemical-action vessel accommodates a substrate in which biochemical reactions are caused by microorganisms. A heat-exchange arrangement is provided in the vessel and removes the heat generated in the substrate by such reactions. The substrate is circulated in the vessel advanced by an advancing arrangement in a closed path which passes through the heat-exchange arrangement. Aerating gaseous medium is introduced into the substrate upstream of the advancing arrangement and in the region of suction generated by the same, and entrained by the circulating substrate so as to supply the oxygen necessary for the aerobic growth of the microorganisms.
Claims5
An apparatus for cooling and aerating a substrate in a fermentation process, comprising a substantially cylindrical container elongated in a substantially horizontal direction and accommodating the substrate to be cooled and aerated;
- a plurality of heat-exchange sections located in said container and each including a number of parallel passages;
- means for advancing the substrate in said container in the direction of said passages;
- means for supplying gaseous aerating medium into said passages to be entrained by the substrate advancing through the passages;
- and said heat-exchange sections encircling said advancing means to provide a uniform aerating and cooling of the substrate through said elongated container.
