Drum-type thermal-insulation fermentation device used for production of bio-organic fertilizer

Abstract

The invention discloses a drum-type thermal-insulation fermentation device used for production of a bio-organic fertilizer. The device comprises a drum-type stirring component and a temperature control component; the drum-type stirring component comprises a roll cylinder, the bio-organic fertilizer is placed in the roll cylinder, and the drum-type stirring component is used for periodically turning the bio-organic fertilizer in the roll cylinder; and the temperature control component is arranged outside the roll cylinder and used for real-time temperature control treatment of the bio-organic fertilizer in the roll cylinder at each stage. According to the device provided by the invention, a temperature control cylinder sleeves the exterior of the roll cylinder, a water temperature is controlled to control a temperature of the organic fertilizer in the roll cylinder, so that the quality of the material fermentation product is ensured; stirring rods are arranged in the roll cylinder, thestirring rods can fully stir materials in the fermentation process of the materials, so that contact of the materials with air is accelerated, and a sufficient fermentation reaction is ensured; and aflow guiding plate in the device is arranged on the inner wall of the roll cylinder in an annular spiral manner, so that guiding of the materials is facilitated.

Description

technical field [0001] The invention relates to the technical field of organic fertilizer fermentation, in particular to a drum-type heat preservation and fermentation device for the production of biological organic fertilizer. Background technique [0002] Organic fertilizer fermentation can quickly decompose organic matter, and at the same time strongly degrade protein, and the fermentation time is short. It can effectively kill harmful bacteria, insects, insect eggs, grass seeds and degrade antibiotic residues in the fermented product. [0003] Composting is a common method of organic fertilizer fermentation. In fact, organic fertilizer fermentation is divided into several stages, including the heating stage, high temperature stage, cooling stage and decomposing fertilizer preservation stage. In the heating stage, the microorganisms in the compost generate a large amount of heat. , continuously increase the compost temperature from about 20 degrees to 40 degrees, and then...

AI Technical Summary

Problems solved by technology

[0006] 1. The existing fermentation drum device has poor temperature control effect, and it often only focuses on heating treatment, while ignoring cooling treatment, which greatly affects the quality of the overall organic fertilizer

[0007] 2. The existing fermentation drum device cannot provide sufficient and uniform stirring for the material during the fermentation process of the material, or the drum is designed as a closed type, resulting in insufficient contact with the air during the fermentation reaction process, thereby affecting the fermentation effect
