Simple Turning Machine

A trough compost turner is a device specifically designed for fermentation processing. By turning and stirring materials within the fermentation tank, it creates a suitable environment for fermentation. It is widely used in fields such as organic fertilizer production. Its core working principle is to use the turning teeth on the mechanical arm to perform a reciprocating motion within the fermentation tank, turning the accumulated materials, allowing them to fully contact the air. This simultaneously regulates the temperature and humidity of the materials, promotes microbial activity, and accelerates the composting and fermentation of the materials.

This equipment adopts a trough structure design, which can realize continuous fermentation operations. Compared with traditional manual turning or ground composting methods, the fermentation efficiency is greatly improved, the fermentation cycle is significantly shortened, and it can effectively control odor and pollution during the fermentation process. It is one of the key equipment for large-scale organic fertilizer production.

What raw materials can be fermented by the trough compost turning machine?

The trough compost turning machine has strong adaptability to fermentation raw materials and can process a variety of organic wastes, as follows:

Livestock and poultry manure

This includes chicken, pig, cow, and sheep manure, which are rich in organic matter and nutrients like nitrogen, phosphorus, and potassium, making them excellent raw materials for producing organic fertilizer. The trough compost turning machine turns the manure to fully ferment it, killing pathogens, insect eggs, and weed seeds, while also eliminating odor.

Crop straw

Corn straw, wheat straw, rice straw, etc. contain a large amount of cellulose, hemicellulose and lignin, which can be converted into organic matter in organic fertilizer through fermentation. The trough compost turning machine can evenly mix the straw with other raw materials to promote the decomposition and maturity of the straw.

Edible mushroom residue

The residue from mushroom cultivation, rich in mycelium and underutilized nutrients, is a high-quality organic fermentation raw material. After fermentation in a compost turning machine, it can be made into highly effective organic fertilizer.

Industrial organic waste

These wastes include organic by-products generated during industrial production processes, such as wine dregs, vinegar dregs, sugar residues, and oil residues. These wastes contain certain organic matter and nutrients, and can be recycled after fermentation by a trough compost turning machine.

Municipal sludge

Sludge generated by municipal sewage treatment plants contains a large amount of organic matter, but may also contain harmful substances such as heavy metals. It must undergo rigorous testing and treatment before it can be used as fermentation raw material. The trough compost turning machine can fully ferment the sludge, reduce its moisture content, and stabilize its properties.

Equipment composition of trough type compost turning machine

The trough compost turning machine consists of several key components that work together to ensure the smooth progress of the compost turning operation. The specific components are as follows:

frame:The frame is the basic supporting component of the trough compost turner. It is usually made of welded steel sections and has sufficient strength and rigidity to withstand the weight of the equipment and the loads generated during operation. Other components such as the travel mechanism and compost turning mechanism are installed on the frame.

Traveling mechanism:The machine consists of a drive motor, a reducer, and wheels, responsible for driving the equipment along the fermentation tank track. The travel mechanism enables the equipment to move forward, backward, and turn. The travel speed can be adjusted according to the fermentation process requirements, generally 0.5-3 meters per minute.

Compost turning mechanism:The core working component of a trough compost turner consists of a hydraulic system, a mechanical arm, and turning teeth. The hydraulic system powers the arm's lifting and swinging motion, allowing it to adjust up and down according to the material pile height. The turning teeth, arranged in a spiral or comb-like pattern, are used to turn and stir the material. These turning teeth are typically made of high-strength alloy steel, offering excellent wear and impact resistance.

hydraulic system:Composed of a hydraulic pump, hydraulic cylinder, and hydraulic valve, it provides power for the compost turning mechanism. The hydraulic system boasts smooth transmission, high output force, and flexible operation, enabling precise control of the robotic arm's trajectory and compost turning depth.

Electronic control system:The system consists of a control cabinet, operating console, and sensors, responsible for controlling the operation of the equipment. The operator can use the console to control the equipment's movement, turning, and other actions. Sensors monitor the equipment's operating status and parameters such as the temperature and humidity of the materials in the fermentation tank in real time, ensuring safe and stable operation.

fermentation tank:While the fermentation tank itself isn't a moving part of the compost turner, it's the basic infrastructure for its operation. Typically constructed of concrete or steel, it's long and narrow, with tracks at the bottom for the turner to travel on. The length, width, and depth of the fermentation tank are determined by production scale and fermentation process requirements. Typically, the length ranges from 10 to 50 meters, the width from 2 to 5 meters, and the depth from 1 to 2 meters.

How does a trough compost turning machine compost organic fertilizer raw materials?

The process of composting organic fertilizer raw materials with a trough-type compost turning machine is a systematic fermentation process that requires strict control of each link.
The specific steps are as follows:

Raw material pretreatment:The collected organic fertilizer raw materials are crushed and screened to remove impurities (such as rocks and plastic). The particle size is controlled within a certain range (generally 2-5 cm) to facilitate fermentation. The carbon-nitrogen ratio and moisture content are also adjusted based on the raw material's characteristics. The carbon-nitrogen ratio is generally controlled at 25-30:1, and the moisture content is controlled at 50%-60%. If the moisture content is too high, dry materials such as straw and sawdust can be added to adjust the moisture content. If the moisture content is too low, water can be added as needed.

Raw materials into the tank:The pre-treated raw materials are evenly laid in the fermentation tank. The laying thickness is determined by the depth of the fermentation tank and the characteristics of the raw materials, generally 0.8-1.5 meters. During the laying process, equipment such as loaders or conveyors can be used for auxiliary operations.

Turning and fermentation:Start the trough-type compost turner and turn the material at the set speed and depth. The turner's mechanical arm descends into the material, and its turning teeth toss it upward, allowing it to fully contact the air and increase its breathability. Furthermore, the friction and collision between the materials during the turning process uniformly raises their temperature, promoting the growth and activity of microorganisms.

During the fermentation process, the frequency of compost turning should be determined based on the temperature of the material. Generally, the first turning is performed when the material temperature reaches 60-70°C. Thereafter, turning is performed every 1-3 days. The specific turning frequency can be adjusted based on the fermentation progress. The entire fermentation cycle generally lasts 15-30 days.

Maturity judgment:When the temperature of the material gradually drops to close to the ambient temperature and the material becomes dark brown with an earthy smell and no obvious odor, it means that the material is mature. At this time, the mature material can be removed from the fermentation tank for subsequent processing (such as crushing, screening, granulation, etc.).
