Product Introduction

US20050077029A1 Heat exchanger for fermentation tank

A device which is used to cool fermentation tanks and which can be used essentially in beer production cooling and maturation includes a vertical heat exchanger which comprises single or doublewall concentric cylinders and is positioned internally at the center of a tank The length and capacity of the cylinders differ depending on the size and shape of the tank

The Design of Airlift Fermenters for use in

increases mass and heat transport efficiency Compared to mechanically agitated stirredtank fermenters airlift fermenters are easier to scale up require less energy to operate and are more adaptable to cultures that are shear sensitive As stirredtank systems grow in size

Standard 45 pitched fourblade turbine 4PBT45 with diameter dD3 was tested placed at position h033H and h066H from bottom of the vessel further referred as h033 and h066 Impeller characterized by axial flow with also strong radial fluid flow mixed flow impeller was set work in two modes upwardpumping UP and downwardpumping DOWN mode for each configuration

The baffle width is 110 or 112 of the tank diameter A gap of about 15 of tank diameter is left between the wall and the baffle to prevent stagnation of fluid near the wall The working aspect ratio of the vessel is between 3 and 5 except in animal cell culture applications where aspect ratios do not normally exceed 2
