The trough type turning machine is an indispensable key equipment in modern organic fertilizer production, especially suitable for large-scale industrial organic waste fermentation treatment. Its main function is to accelerate the aerobic fermentation process of organic matter under controlled environment, and convert biomass waste into high-quality organic fertilizers. The following is the working principle and significant advantages of the trough type flipping machine:

working principle

Loading materials: Mix the organic waste to be fermented (such as livestock manure, crop straw, kitchen waste, etc.) with necessary auxiliary materials (such as sawdust, straw) and fermentation agents in proportion, and fill them into the pre prepared fermentation tank. Ventilation and flipping:

The trough type stacker uses a bucket or screw propulsion device installed on it to periodically flip the materials in the trough while introducing fresh air.

This can ensure sufficient oxygen inside and outside the reactor, maintain aerobic conditions, promote the active reproduction of beneficial microorganisms (such as bacteria and fungi), and accelerate the decomposition of organic matter.

Temperature control:

Microbial activity generates a large amount of heat, and the trough type turning machine can evenly distribute the generated heat through the turning action, prevent local overheating, and help maintain a suitable fermentation temperature range (usually between 50 ℃ and 65 ℃), accelerating the fermentation rate.

Moisture and pH management:

The air introduced during the flipping process can help regulate the moisture content of the materials, avoiding anaerobic environments caused by excessive humidity, and adjusting the pH value to create an environment conducive to microbial activity.

advantage

Improve efficiency: The trough type stacker has a high degree of automation, which can significantly shorten the fermentation cycle. Compared with traditional natural stacking fermentation, it can shorten the fermentation time from several months to several weeks or even shorter.

Uniform fermentation: Due to regular flipping and aeration, the material is heated and subjected to microbial action more evenly, avoiding local decay and odor production, and improving fermentation quality.

Controllable environment: The equipment can provide a stable fermentation environment that is not affected by weather changes, and fermentation operations can be carried out throughout the year.

High space utilization: Compared to flat stacking, trough fermentation saves space and is suitable for large cities with limited land resources and industrial farms.

Reduce pathogens and pests: High temperature and aerobic conditions can kill most harmful pathogens and parasite eggs, ensuring safety and hygiene.

Energy conservation and environmental protection: reduce greenhouse gas emissions, avoid methane and ammonia emissions caused by open-air storage, and comply with sustainable development and environmental protection requirements.

The application of trough type turning machines makes the management and utilization of organic waste more efficient, controllable, and environmentally friendly, which is of great significance for promoting the development of agricultural circular economy and green ecological agriculture.

Sheep manure is a high-quality organic fertilizer source, rich in various nutrients such as nitrogen, phosphorus, potassium, etc., and is very suitable for making organic fertilizers. The process flow for processing it into powdered organic fertilizer is roughly as follows:

1. Raw material preparation

Sheep manure collection: Collect fresh or slightly dried sheep manure from the pasture, paying attention to removing impurities such as stones, plastic sheets, and other non organic matter.

Pre treatment: If the moisture content of sheep manure is high, it may be necessary to use a solid-liquid separator for dehydration treatment to reduce the moisture content to about 40% to 50%.

2. Fermentation treatment

Mixed composting: Mixing sheep manure with other organic waste (such as rice straw, corn stover, legume crop residues, etc.) in a certain proportion to help regulate the carbon nitrogen ratio and initiate the fermentation process.

Inoculation strain: In order to accelerate fermentation, specialized fermentation agents such as EM bacteria, Bacillus subtilis, etc. can be added.

Pile flipping and ventilation: Regular flipping and ventilation are carried out through an organic fertilizer flipping machine to ensure sufficient oxygen supply, maintain a suitable fermentation temperature (50 ℃~60 ℃), and promote organic matter decomposition.

3. Drying

Natural drying: Spread out the fermented organic fertilizer and let it air dry naturally for a few days to further reduce the moisture content to 10% to 15%.

Alternatively, an organic fertilizer dryer can be used for manual drying, especially in adverse weather conditions, to achieve the desired moisture content more quickly.

4. Crushing

Use an organic fertilizer grinder to grind the dried organic fertilizer raw materials into finer powder for subsequent processing.

5. Mixing and sieving

Secondary mixing: If necessary, other elements (such as trace elements, biological agents, etc.) can be added for secondary mixing to ensure uniform composition.
