How To Control The Temperature In Organic Fertilizer Compost

The temperature, humidity, PH value and C/N ratio of the compost during the fermentation process are important factors affecting the effect of the compost. The temperature during the fermentation process of organic fertilizer can be summarized as follows: the temperature rises steadily in the early stage, the high temperature in the middle part remains moderate, and the temperature decreases slowly in the later stage, and the temperature control directly affects the maturity of organic fertilizer in the later stage.

Today, mainly explain how to control the temperature in the organic fertilizer fermentation

The compost temperature of organic fertilizers is mainly controlled by pile turning and forced ventilation. Here, SX can provide you with processional compost turner. In the early stage of fermentation, even if the temperature of the fermentation is slow or even does not rise, the pile must be turned or ventilated after 48 hours to avoid the formation of an anaerobic environment in the high temperature stage. When the pile temperature is lower than 50°C, the pile should be turned in time (the reduction of oxygen will cause the reaction in the pile to gradually decrease, thereby reducing the temperature), increase the pile temperature, promote the decomposition of organic matter and kill harmful microorganisms. In the late stage of fermentation, once the temperature exceeds 65°C, The pile must be turned in time to prevent carbonization and ammoniation of organic matter. Click here to learn more.

During aerobic fermentation, temperature control is very important. If the temperature is too low, the maturity standard will not be met. If the temperature is too high, the nutrients in the compost will be easily lost. The temperature in the compost is within 30 cm from the outside to the inside. Therefore, the metal rod of the thermometer used to measure the temperature must be longer than 30 cm. When measuring, it must be inserted into the compost for more than 30 cm to correctly reflect the fermentation temperature of the compost. In SX, we also have compost machine with temperature monitor on sale, It is in-vessel fermentation tank.

How to read the compost temperature
1. When reading the temperature, make sure the thermometer goes deep into the pile, leave the thermometer for a while to allow the temperature to stabilize before taking the reading, then move it to a new location (including several locations at different depths from the top edge ).
2. The temperature of the pile depends mainly on the moisture content and chemical composition of the raw material components.
3. There is a certain gradient in the change of fermentation temperature. For the system with bottom ventilation, the highest temperature is about 2/3 of the bottom or higher.

Groove Type Compost Machine For Small Scale Fertilizer Fermentation

The small fermentation equipment turner is a mechanical equipment developed and produced based on dynamic composting. The early composting process was static composting, which was often converted into anaerobic fermentation due to insufficient oxygen supply, which would produce a large amount of odors such as hydrogen sulfide, and have Explosion risk, later in the middle of the last century, the German BACKHUS (Bakus) company developed a mechanical device to improve the oxygen supply and material shape in aerobic fermentation compost, called the fertilizer turning machine.

Groove type compost turner is an ideal small scale compost turner, which is often called the guide rail turner. It can be used to ferment and turn over organic wastes such as livestock and poultry manure, sludge garbage, sugar mill filter mud, slag cake and straw sawdust, etc. It is widely used in fermentation and dehydration of organic fertilizer plants, compound fertilizer plants, sludge waste plants,  horticultural farms,etc. Click here for details
