This case study details the implementation of a customized racking system designed to optimize a 30-meter by 10-meter cultivation space for the production of both Shiitake and King Oyster mushrooms. The project required distinct racking solutions tailored to the specific growth needs and cultivation methods of each mushroom variety.
The Challenge: Dual-Crop Cultivation Space
The client needed to equip a 30m x 10m growing room to efficiently cultivate two different types of mushrooms: Shiitake and King Oyster. This presented the challenge of designing and integrating two separate racking systems within the same facility, each optimized for the particular mushroom species while maximizing the overall capacity and operational workflow.
Our Tailored Technical Solution
We developed a specialized racking plan that divides the cultivation space to accommodate the unique requirements of Shiitake and King Oyster mushrooms, utilizing steel-plastic pipe construction for durability and hygiene.
Shiitake Mushroom Racking (Rmushroom)
For Shiitake cultivation, a multi-tiered racking system was designed with specific dimensions and layout to support the growth substrate and facilitate harvesting.
· Dimensions: Racks are 30 meters long and 2 meters high.
· Configuration: The layout includes:
o Three rows of middle racks, each 1.2 meters wide.
o Two rows of side racks, each 0.6 meters wide.
· Layer Structure: The racks feature 6 layers, with approximately 0.3 meters of vertical space per layer, suitable for Shiitake substrate bags.
· Support: Longitudinal bars are strategically placed on each layer to provide a stable surface for the mushroom bags. The specific number of longitudinal bars per layer was a point of discussion to optimize support based on bag size and weight.
· Layout: The arrangement of these racks within the 10-meter width of the room includes designated aisle spaces to allow for access and management (as illustrated in the technical diagrams).
King Oyster Mushroom Racking (Mrprack)
The King Oyster cultivation required a different approach, utilizing a grid rack system to support individual mushroom bags or blocks.
· Dimensions: Grid rack units are designed to be 30 meters long and 2 meters high.
· Configuration: The system utilizes 0.3-meter wide grid rack sections that can be combined, for example, to create wider 0.6-meter sections.
· Grid Design: The core of the King Oyster system is a grid mesh with cell dimensions of 0.2 meters by 0.2 meters. These individual cells provide dedicated placement points for King Oyster substrate units.
· Capacity: The proposed layout provides for approximately 13,500 grid positions, offering significant cultivation capacity for King Oyster mushrooms within the designated area.
· Layout and Access: The grid racks are arranged with aisles allowing workers access for monitoring and harvesting from the front face of the racks (as depicted in the technical diagrams). The aisle widths are planned to facilitate efficient operations.
Integrated Facility Design
The overall plan integrates both the Shiitake and King Oyster racking systems within the 30m x 10m room. The layout considers optimal spacing for airflow, operational access via planned aisles, and structural stability for the full length and height of the racks.
Materials and Construction
Both racking systems are constructed using durable steel-plastic pipes and components, chosen for their longevity, resistance to the humid conditions of mushroom cultivation, and ease of cleaning.
