Vacuum treatment of an input stream without ruining delicate output fractions

A method for detaching apart the membrane and mineral fractions of empty broken egg shells comprising the steps of:

• providing a main processor that operates at a level of vacuum with a pneumatic-carrier admission port, a spaced-away pneumatic-carrier syphon port, and a drain;
• providing the main processor with a through-current of a hot pneumatic carrier admitted in through the admission port and syphoned out the syphon port;
• supplying empty broken egg shells, inclusive of a water content, inherently some of which is presumptively contained in the gas-exchange pores of the egg shells that extend through both the membrane and mineral layers thereof;
• at a relatively elevated pressure, pre-heating the empty broken egg shells in order to elevate the bulk temperature to above what corresponds to the boiling temperature for water within the main processor's vacuum level;
• introducing the pre-heated empty broken egg shells into the main processor, and onto the through-current of the hot pneumatic carrier for mixing therewith, whereby a small percentage of the water content flashes into steam, this presumptively promoting the membrane fraction to eject or detach from attached or adhered shards or powder of the mineral fraction;
• suspending in the current of the hot pneumatic carrier suspension particles from out of the detaching membrane and mineral fractions and carrying such out the syphon port;
• and
• draining non-suspending residuals out the drain.

A method for detaching apart the membrane and mineral fractions of empty broken egg shells comprising the steps of;

• providing a main processor that operates at a level of vacuum with a pneumatic-carrier admission port, a spaced-away pneumatic-carrier syphon port, and a material-introduction passage comprising in series a pressure isolation device for introducing material into the main processor while maintaining the level of vacuum in the main processor and then a grinder for grinding the material outputted by the pressure isolation device within the vacuum level of the main processor;
• providing the main processor with a through-current of a hot pneumatic carrier admitted in through the admission port and syphoned out the syphon port;
• supplying empty broken egg shells, inclusive of a water content, inherently some of which is presumptively contained in the gas-exchange pores of the egg shells that extend through both the membrane and mineral layers thereof;
• at a relatively elevated pressure, pre-heating the empty broken egg shells in order to elevate the bulk temperature to above what corresponds to the boiling temperature for water within the main processor's vacuum level;
• introducing the pre-heated empty broken egg shells into the main processor through said material-introduction passage including said pressure isolation device and grinder for mixing with said through-current of the hot pneumatic carrier, whereby a small percentage of the water content flashes into steam, this presumptively promoting the membrane fraction to eject or detach from attached or adhered shards or powder of the mineral fraction;
• and
• suspending in the current of the hot pneumatic carrier suspension particles from out of the detaching membrane and mineral fractions and carrying such out the syphon port and not non-suspending residuals.
