Problems solved by technology

In this heating method, since the heat transfer surface of the heat medium sleeve installed around the treatment tank is about half of the treatment tank, the object to be treated that is stirred up to the top of the treatment tank by stirring will adhere to the rotating shaft, Stirring blades (including brackets) will not be in contact with heat for a long time, and the moisture content of the treated material will easily become uneven, and the mixed fertilizer product will also become unstable.
This is because the heat transfer efficiency of the stirring blades and rotating shafts that contact the object to be processed in the inner space of the treatment tank is low. If the heat transfer area of ​​the treatment tank is increased in order to improve this point, the device will be extremely damaged. growing problem

Abstract

In the heating method, the following two heating-methods are selectively applied to a to-be-treated matter by switching set temperatures in conformity with the kind and properties of animals and vegetables contained in the treated matter. That is, in one heating method for oxidative-decomposition treatment, the heating temperature is controlled to 25-130[deg.]C, and in the other heating method, the heating temperature is controlled to 25-250[deg.]C to conduct oxidative-decomposition treatment and low temperature thermal decomposition treatment in combination.

Description

technical field [0001] The present invention relates to a method of heat treatment of biological organic waste and a device used in the method, especially for sludge, excrement, etc., which have a high moisture content and emit a large amount of bad odor, etc., which have been difficult to treat until now. Biological organic waste is used as the object to be processed, and the relatively fresh processed object is converted into feed, the fresh one is composted, or the one rich in fertilizer components is fertilized, etc., according to the orientation of the processed object, etc. Select the treatment method to increase the heat transfer area in the treatment tank to reduce heat loss and improve thermal efficiency, an indirect heating treatment method for biological organic waste that can form stable recycled products in a short period of time and the method used installation. Background technique [0002] As a treatment method of biological organic waste, many methods have ...
