Groove‑Type Compost Turner

The OFEC Groove‑Type Compost Turner is one of the most widely used aerobic fermentation units at the front end of organic fertilizer production lines. Available in two models – the trough-type compost turner and the trough-type hydraulic compost turner – it is specifically designed for slot-type composting processes. By turning the compost pile, the material is fully exposed to oxygen, effectively resolving issues such as oxygen deficiency, uneven temperature distribution, and prolonged fermentation cycles. When combined with a transfer trolley, a single machine can serve multiple troughs, significantly improving compost quality and yield.

Product Overview

The groove‑type compost turner (including both trough-type and trough-type hydraulic versions) is one of the most widely used aerobic fermentation and compost turning equipment currently available. Employing a trough-type fermentation process, the machine uses mechanical turning to thoroughly mix and aerate the material within the trough, accelerating organic matter degradation and maturation. The equipment can be used with a transfer trolley to switch between multiple troughs, enabling a highly efficient “one machine, multiple troughs” production model.

The OFEC groove‑type compost turner offers convenient operation, short fermentation cycles, thorough turning, and minimal pollution. It is easy to scale up and expand, making it the ideal choice for slot-type fermentation systems in medium to large-scale organic fertilizer plants.

Equipment Components

The groove‑type compost turner mainly consists of the following components:

● Frame: Supports the entire equipment

● Rail Travel Mechanism: Moves along the trough rails

● Turning Device: Core turning component that turns and mixes the material

● Hydraulic System: Controls turning depth and lifting (hydraulic model)

● Drive System: Drives the turning device

● Control Cabinet: Manual/automatic control of equipment operation

● Transfer Trolley: Enables one machine to serve multiple troughs

Working Principle

The groove‑type compost turner adopts a trough fermentation structure, where composting material is placed in fixed fermentation troughs. The machine travels along rails on the trough, using the turning device to turn and mix the material, ensuring thorough oxygen exposure throughout the pile and promoting successful aerobic fermentation.

Transfer Trolley Integration: A single turner can be paired with a transfer trolley to switch between multiple fermentation troughs, significantly improving equipment utilization and production efficiency while reducing equipment investment costs.

Control System: Equipped with a centralized control cabinet, the machine supports both manual and automatic control modes, offering flexible and convenient operation.
