Simple Compost Turning Machine

The simple compost turning machine is a lightweight piece of equipment designed specifically for small- to medium-scale organic fertilizer fermentation. Featuring a streamlined channel-based design, it combines the key advantages of low cost, ease of operation, efficient turning, and a compact footprint. It enables uniform turning and oxygenation of organic materials——significantly shortening the fermentation cycle——without the need for complex civil engineering or specialized technical expertise.

Working Principle of the Simple Compost Turning Machine

The working principle of the simple compost turning machine relies on two key technical mechanisms: mechanical transmission and aerobic fermentation. Upon startup, the motor transmits power directly to a cycloidal pin-wheel reducer, which then drives the rotation of the turning drum via a sprocket-and-chain system. Turning blades (or rake teeth)——arranged in rows or a spiral pattern on the drum——turn, mix, and break up the material within the fermentation channel while simultaneously throwing it backward.

Specifically, the equipment travels at a constant speed along rails on both sides of the fermentation channel; the turning drum rotates at a low speed, allowing the rake teeth to penetrate deep into the material layer. This process turns anaerobic material from the bottom to the surface and moves surface material downward, ensuring thorough contact between the material and oxygen. This oxygenation through turning allows the pile temperature to rapidly rise to the optimal fermentation range of 55-70℃, effectively eliminating pathogens and insect eggs. While traditional composting methods require a 30-day fermentation cycle, the use of this equipment reduces the time to just 7-15 days.

Suitable Materials and Application Scenarios for Simple Compost Turning Machines

Suitable Materials

The simple compost turner can process livestock and poultry manures (such as chicken, pig, cattle, and sheep manure) as well as organic solid wastes like straw powder, spent mushroom substrate, distillers' grains, municipal sludge, and decomposed kitchen waste. Its structure has been optimized for high-moisture, high-fiber, and slightly viscous materials, ensuring smooth operation without tangling or clogging.

Application Scenarios

Small and medium-sized organic fertilizer plants: Centralized decomposition of organic raw materials

Family farms: Processing on-site waste such as straw and manure

Livestock cooperatives: Handling manure and waste from nearby livestock farmers

Horticultural nurseries and button mushroom farms: Fermentation, decomposition, and moisture reduction operations

What are the advantages of the simple compost turning machine?

Controllable costs and low investment threshold

The purchase cost of the simple compost turner is only 30%–50% that of large-scale models. It requires no custom civil engineering or complex electrical control systems; it can be installed and used directly with standard prefabricated fermentation troughs. Installation and commissioning can be completed by just 1-2 people, significantly reducing infrastructure and equipment budgets for small and medium-sized enterprises.

Easy operation; no specialized training required

The control system features simple push-button controls, supporting manual start/stop and speed adjustment. General workers can master the operation after brief training, requiring no specialized technical background. A soft-start design minimizes startup impact. A single operator can manage the entire process, from feeding to turning.

Uniform fermentation and excellent decomposition results

The rake-style turning mechanism ensures deep penetration with no "dead zones" in the fermentation mass. With a turning uniformity of over 90%, it effectively improves pile aeration, preventing issues such as incomplete decomposition or strong odors caused by localized anaerobic conditions. The fermentation cycle is shortened by 25%-40%, resulting in more thorough decomposition of organic raw materials.

High adaptability and versatile application

The equipment handles various organic fermentation materials with moisture content ranging from 38% to 58%, allowing for flexible material switching without equipment modification. It can be installed and operated without the need for paved or hardened ground. It can also be paired with a transfer carriage to serve multiple troughs with a single unit, greatly enhancing equipment utilization.

With “simplicity, cost-effectiveness, and ease of use” as its core strengths, the simplecompost turning machine is precisely tailored to the fermentation and processing needs of small- and medium-scale organic waste operations. Offering a low barrier to entry, straightforward operation, and reliable turning performance, it solves practical challenges faced by small-to-medium livestock farms and organic fertilizer plants——namely, the inability to afford large-scale equipment and the inefficiency of manual pile turning.

Whether for processing livestock manure in rural areas, standardized mass production at small organic fertilizer plants, or on-farm fertilizer production for family farms, this simple trough type compost turner represents a highly cost-effective choice that balances economy with practicality.
