The Neptune Drum Roaster has exceptional quality and functionality, a Neptune drum roaster guar­an­tees ex­quis­ite roasts. It is avail­able with nom­i­nal out­puts of 240, 500, 1,500 and 3,000 kg/h.
The newly de­vel­oped ad­just­ment op­tions to the roast­ing pro­file make the Neptune the ideal roaster for espresso and spe­cial cof­fees with par­tic­u­larly high aroma de­vel­op­ment. Thanks to its solid con­struc­tion and low main­te­nance re­quire­ments, it is also a par­tic­u­larly re­li­able part­ner when it comes to in­stant cof­fee pro­duc­tion. It is not only the Neptune’s im­pres­sive qual­ity that is so con­vinc­ing, also its ex­cep­tional func­tion­al­ity. The vari­able drum ro­ta­tion speed en­ables shorter cycle times, the spe­cial shovel mech­a­nism en­sures gen­tle and op­ti­mal mix­ing, and the ef­fec­tive cool­ing sys­tem pro­vides you with even greater as­sur­ance of con­sis­tent prod­uct qual­ity. On top of all this, the com­bi­na­tion of an in­fi­nitely ad­justable burner, low en­ergy con­sump­tion and max­i­mum ther­mal en­ergy util­i­sa­tion make this the only drum roast­ing sys­tem of its kind in the world.
