The aerobic compost tank, also know as organic fertilizer producer, is a specialized facility designed for the process of aerobic composting. It provides an ideal environment for the decomposition of organic materials with the help of oxygen.

It is an important device in the field of organic waste treatment and compost production, playing a significant role in promoting environmental protection and sustainable development.

Working Principle

In an aerobic compost tank, aerobic microorganisms such as bacteria,fungi and actinomycete play a crucial role. They break down organic waste like livestock and poultry manure, kitchen scraps, agricultural residues and wastewater in the presence of oxygen. The tank is designed with oxygen supply systems. This allows fresh air to enter, ensuring that oxygen is constantly available to the microorganisms inside. Aerobic microorganisms thrive in this oxygen - rich environment. These microbes break down the complex organic compounds in the waste materials. The temperature inside the tank can rise significantly, often reaching 45 - 70°C during the active composting phase. This high heat helps to further break down the materials and also kills harmful pathogens, weed seeds, and other unwanted organisms in the waste.

Structure and Design

1) Tank Body

The tank body is the main enclosure of the organic fertilizer producer, which is made of corrosion - resistant stainless steel with high - density polyethylene. It is designed to be airtight to prevent the leakage of odors and harmful gases during the fermentation process. The size of the tank body varies according to the processing capacity, ranging from small - scale units for individual farms to large - scale industrial - sized tanks.
2) Agitation System

An agitation system, including agitation shift, agitation blades and gear, is installed inside the tank. Its function is to mix the organic waste evenly. Regular agitation ensures that all parts of the input are exposed to oxygen, heat, and microorganisms, which promotes uniform fermentation.
3) Heat Recovery System

The waste heat generated during fermentation is recovered by an external heat exchanger and transferred back into the fermentation tank, reducing the pressure of fermentation temperature rise and helping to maintain the fermentation temperature. This system not only helps to shorten the fermentation time but also reduces electricity consumption and saving costs for users.
