Apparatus for producing feeds comprising dried and fermented animal and plant residues and dried and fermented fertilizers

Abstract

In organic waste treatment, initial investment and running costs are suppressed, and inexpensive and good-quality dried and fermented feeds and fertilizers are manufactured from animal and plant residues. The animal and plant residues having been reserved / accumulated in a fermentation tank and generated fermentation heat is emitted / sprayed with air into a space in the fermentation tank and repeatedly circulated within the apparatus so that an evapotranspiration action is efficiently performed, oxygen required for fermentation is uniformly supplied so as to keep a favorable fermentation environment, and an apparatus for producing good-quality dried and fermented feeds and fertilizers is provided.

Description

technical field [0001] The invention relates to a device for producing dried fermented feed, dried fermented fertilizer and the like by using animal and plant residues with the functions of turning organic waste into feed and fertilizer. Background technique [0002] In the past, there were many plans for organic waste treatment systems, but due to the high initial investment and operating costs, the reuse of organic waste could not fully play a role. [0003] In addition, there are many proposals on fermentation and drying methods and their devices, which can be roughly divided into three categories. The first category is natural fermentation by switching operations in a flat state, the second category is fermentation and drying using a heating and stirring device, and the third category is fermentation and drying methods using a reduced-pressure drying device. [0004] In the past, it took a long time and a large workplace to realize feed and fertilizer through natural fe...

AI Technical Summary

Problems solved by technology

[0005] In terms of heating and stirring devices, due to the high cost of heating and the small contact area and chance of the treatment object contacting the air through stirring, it is not easy to evaporate outwards, resulting in waste of energy.

[0006] In terms of decompression drying devices, there are also problems of high heating costs and large initial investment, and it is also difficult to manage the temperature in the device to adapt to the fermentation state
