Process procedure
- filling by containers with lifting tipping station1
- suction during opening the hopper through prefilter h9 and sterile filter H1411
- crushing with single shaft shredder2
- filling the distribution screw und bunker3
- filling of the autoclaves by screws inside6 7
- reversing movement of the autoclave screws throughout the process
- heating with steam up to 138 ° C / 3.5 bar abs.
- holding time in saturated steam at 138 ° C / 3.5 bar abs. 15 min.
- drain pressure and dry
- emptying the waste via process screw and conveyor belt10
Sterilization of the hopper, shredder room, distribution screw, bunker and filters
1. steam through-flow at 104 °C / 1.15 bar abs.
2. holding time in saturated steam at 104 °C / 1.15 bar abs.
Behavior of the system in case of failure of media and components
In the event of a failure of electricity, steam and compressed air as well as in the event of a failure of the control, the machine goes into a safe operating state; valves and covers remain closed until the machine is ready for operation again and the processes can be completed.
