Back-tilting and bed waste removal

In most tilt-cake systems the cake is autoclaved in the vertical position. The HESS plants have combined the advantages of the tilt-cake and flat-cake system.

After the cutting is completed, the cake is tilted back by 90° onto a cooking frame. In the HESS system no part of the mould or platform used for cutting goes into the autoclaves. After the cake has been tilted back into the horizontal orientation, the bottom/bed waste will be removed before autoclaving. Autoclaving the cake while lying horizontally on the cooking frames allows efficient autoclave loading and most importantly, will prevent most of the sticking of the layers, which is a typical disadvantage of the traditional tilt-cake systems.

HESS SYSTEMS PRODUCE NO PROCESS RELATED WASTE!
