Reduced-pressure fermenting and drying apparatus

Abstract

The invention provides a reduced-pressure fermenting and drying apparatus, which can effectively remove odor generated by processed materials, prevent odor from spreading outside and further prevent degradation caused by rotten parts of the processed materials. The reduced-pressure fermenting and drying apparatus comprises a drying machine having a processing chamber where organic processed materials with microorganisms are input; a heating sleeve pipe arranged on the drying machine and heating the processed materials; a heating stirring part configured inside the processing chamber of the drying machine in a way to be capable of rotating and applied for heating and stirring processed materials; a condensing part condensing moistures generated from organic wastes to generate condensed water; a gas-liquid separation device guiding the mixture of the condensed water in the condensing part and the air in the processing chamber and further separating the guided mixture into condensed water and air; and an absorption pump connected with the downstream side of the gas-liquid separation device and absorbing condensed water in the condensing part and the air in the processing chamber towards the gas-liquid separation device.

Description

technical field [0001] The present invention relates to a reduced-pressure fermentation drying device for heating and fermenting an object to be processed under reduced pressure. Background technique [0002] As a device for drying organic treated objects with high water content such as excess sludge or water-containing garbage produced in sewage treatment plants, it is known to heat the processed objects under a reduced pressure environment and make them dry. A vacuum fermentation and drying device for fermentation and drying. In such a reduced-pressure fermentation and drying apparatus, various deodorization measures are taken because the object to be processed has a relatively strong odor. [0003] The applicant has previously proposed a vacuum fermentation and drying device that implements odor countermeasures, such as Figure 9 As shown, it is equipped with: a processing chamber 111 that utilizes a vacuum pump 104 to decompress the inside; a condensing unit 115 that is...

Problems solved by technology

[0009] However, in the above-mentioned conventional vacuum fermentation and drying apparatus, the condensed water or air from the treatment chamber 111 is guided to the cooling tower 105 and mixed with the cooling water, so there are many objects to be deodorized, and there is a problem that the deodorization treatment efficiency is low.

In addition, there is a problem that the cond...
