Solid High-Temperature Fermentation Drum with Labyrinth Seals

The fermentation system is divided into multiple independent fermentation chambers within a single reactor unit, allowing parallel processing of multiple batches simultaneously. This segmentation enables continuous operation without requiring large land area, as each chamber can be independently filled and fermented while others are in different stages of the process.

The patent transitions from horizontal ground-level composting to vertical three-dimensional reactor structure. The reactor utilizes vertical space with multiple stacked chambers, dramatically reducing the ground footprint while maintaining or increasing total fermentation capacity. This dimensional change allows high-density fermentation units to be placed in urban environments.

The fermentation chambers are designed to be self-aerating through natural convection currents generated by temperature differences and density variations within the chamber. The system does not require external blowers, motors, or complex ventilation infrastructure, as the fermentation process itself generates the necessary air circulation patterns for oxygen distribution.

The patent removes the complex mechanical ventilation system, turning devices, and automated control infrastructure from traditional trough composting. Only simple manual filling and covering operations remain, eliminating the need for expensive motors, sensors, and control systems while maintaining effective fermentation.

Instead of one long drum, the system uses multiple short cylindrical chambers stacked vertically. Each chamber is a complete fermentation unit with its own filling and discharge capabilities. This segmentation allows each drum to be much shorter (comparable to its diameter) while the stack configuration provides the necessary total volume, dramatically reducing manufacturing cost.

The patent stacks multiple short drums vertically rather than using one long horizontal drum. This vertical arrangement achieves the required total fermentation volume without increasing individual drum length, making each drum easier and cheaper to manufacture while maintaining high fermentation efficiency through the multi-chamber configuration.

The patent completely removes the shoveling plate attachment from the drum inner wall, eliminating the adhesion problem and the additional energy required to drive the plates. Instead, the system relies on natural material movement during filling and discharge operations, plus convection currents for air mixing, achieving effective fermentation without mechanical stirring components.

The fermentation mixture itself generates convection currents through temperature and density differences that provide sufficient air circulation and material mixing without mechanical assistance. The system uses the fermentation process's own thermal energy to drive air flow and material movement, eliminating the need for powered shoveling plates.

The system uses the high temperature generated during active fermentation (reaching 60-70°C) to thermally treat and sanitize the odor gases before they are discharged. The fermentation heat, which would otherwise be wasted, is redirected through the odor treatment system to destroy harmful compounds and reduce odor intensity, converting a harmful byproduct into a beneficial sanitizing agent.

A simple thermal processing chamber serves as an intermediary between the fermentation reactor and the atmosphere. Odor gases pass through this chamber where they are heated by the fermentation process temperature, causing thermal decomposition of harmful compounds and condensation of moisture, before the treated gas is discharged to the environment.
