Differences in Fermentation Between Hydraulic Compost Turning Machines and Windrow Compost Turning M

Both hydraulic compost turning machines and windrow compost turning machines are used for aerobic fermentation and turning of organic fertilizers, but their operating modes, fermentation effects, and process standards are completely different, directly affecting the uniformity of composting, fermentation cycle, and finished product quality. They also have significantly different suitable factory sizes.

First, the operating modes and fermentation environments differ. Hydraulic trench compost turners use a fixed, closed-loop fermentation system within a trough. The equipment operates by reciprocating along a track, keeping the material fixed within the fermentation trough and unaffected by weather conditions. The fermentation environment is stable and controllable, allowing for precise temperature, humidity, and oxygen control. Tracked compost turners use an open-loop fermentation system on the ground, where the equipment moves freely and turns the compost without the need for troughs. This provides greater flexibility in site selection, but outdoor operation is susceptible to weather interference. Rainwater can cause excessive moisture content in the material, leading to cooling and sluggish fermentation, while dry weather can cause dust and rapid water loss from the material.

Second, the uniformity of turning and the oxygen supply effect differ. Hydraulic trough-type composting offers greater depth and more precise, stable trajectory, thoroughly turning over materials, completely breaking up hardened layers, ensuring even oxygen supply between layers, eliminating fermentation dead zones, and rapidly expelling harmful gases such as ammonia and hydrogen sulfide. Tracked composting, however, is affected by ground unevenness, resulting in significant trajectory deviations, inconsistent turning depth, and incomplete turning of materials at the edges and bottom of the pile, easily leading to localized oxygen deficiency, suffocation, souring, and uneven composting.
