(US4909825-A)      Drying and conditioning pasty material, such as chicken manure strands, chips, granules, pellets, fibres, involves treatment in closable vessel contg. elements carrying selective microorganisms.    With the vessel closed to reduce NH3 escape a mixt. of air and CO2 is forced into the loosely piled material, so that temp. rise to about 80 deg C provides optimal conditions for the microorganism. At the end of treatment a greater amt. fo air is injected for drying, beginning with pile temp. redn. to below 60 deg C as a signal of treatment ended. Pref. the CO2 is flue gas.    ADVANTAGE -   Large scale process is of energy costs. @(6pp)@    (EP210196-B)      A process for drying and conditioning pasty substances such as chicken manure which are at least partly organic and are in the form of strands, chips, granules, pellets or fibres, which, when mixed with organic or inorganic moulded stable materials, result in a loose, air permeable pile of material, characterised in that the process is carried out in one and the same apparatus and in two phases, a microbiological phase immediately followed by a flow-through drying phase, such that, in the microbiological phase, a mixture of air and carbon dioxide is passed through said pile to reduce the pH and to provide optimal environmental conditions for selective microorganisms that have been settled on moulded, stable carrier elements and populate the pile of material so as to enable all or part of the organic fractions of the respective substances to be processed aerobically, the resulting carbon dioxide being carried along by the flow of air, the air being heated by the heat released from the process, water vapour is carried off from the pile of material and the temp. in the pile of material being allowed to rise to approximately 80 deg. C, the quantity of the controlled and conditioned air being controlled, for example, by means of temp. sensors and/or humidity indicators disposed in the pile of material, so that water vapour saturation does not occur, nor does the temp. of the pile of material approach the cooling limit temp. whereupon the microbiological phase is changed to the flow-through drying phase when the temp. in the pile of material has dropped, for example to below 60 deg. C, in that the quantity of not-moisture-saturated air flowing through the pile of material is increased to a multiple of the quantity of air used in the microbiological phase and the flow-through drying phase is terminated when the desired degree of desiccation is reached in the pile of material.    (SU1709902-A3)      Poultry droppings or similar pasty materials are dried and conditioned in two stages in the same vessel. In the first microbiological stage, the droppings are placed on elements carrying selective aerobic microorganisms to create optimum conditions. When the temp. drops, the second (flow-through) stage uses as many times greater air flow rate to dry out the material.    ADVANTAGE -   This saves energy costs and removes all evil smells so that the resulting manure can be sold, e.g. in supermarkets.
