The invention presents a covered cavity kiln pyrolyzer with modulated means of rotation, to promote mixing and exposure of the biomass to heat, thereby allowing complete and efficient pyrolysis of biomass therein. The invention has a portal arrangement for simultaneous entry of fuel and air alongside the exit of emissions and flames to a separate hood structure. In addition to rotational modulation for mixing, the rotational capabilities of the kiln also permit the removal of processed charcoal when the portal is turned downward. The invention also has a system of internal prongs for mixing and sifting removal of char, as well as automated fuel delivery mechanisms and a system of openings to allow insertion of pipes and sensors into the kiln for monitoring and for additional delivery of reagents for better modulation and efficiency by a user during the pyrolyzation process.

A hermetic compressor assembly is disclosed including a motor compressor disposed within a hermetically sealed housing, wherein the housing has an oil sump in the bottom thereof from which oil is drawn to lubricate the compressor mechanism. An electric drive motor includes a vertical rotor having a lower axial end ring with rotor counterweight die cast therein, whereby turbulence and resulting agitation of the oil in the oil sump is prevented during rotation of the rotor. By die casting the counterweight within the end ring additional attachment parts and manufacturing steps are eliminated.
