Changes in environmental legislation are imposing ever-increasing emphasis on emission control. The Dalsem Mushroom Projects indoor composting technology for Phase-I fermentation is a guaranteed response to these changes.
Our Phase-I indoor composting combines all the mixing equipment, moisturising, and fermentation in compliance with the most stringent requirements. The closed vessel composting is placed inside a completely enclosed building that is kept under a constant negative air pressure. No air, water, or noise emissions can be emitted without going through a series of scrubbers, filters, and the like.
In order to meet the demand with a lower available budget we also supplies integrated outdoor composting for Phase-I in open-bunker or on aerated floor, both with completely controlled air-distribution.
Concrete grids are available for tunnels 3 and 4m wide. Average opening 40%.
Support option 1: by lateral stub walls.
Support option 2: by support beams.d
Spigot floors are designed for phase I and phase II facilities.
Usual diameter of the PVC pipes is 160 mm. Spigots come as a standard product.
Air volumes: 10 to 15 m3/hr per ton of phase I compost; 200 m3/hr per ton of phase II/III compost. Pressures: 3500-6000 Pa, depending on flling height.
Retaining boards are available in two different designs.
Type 1: for compost tunnels wit a grid floor, max. 4 m. Comes with aluminium posts and aluminium boards. Reinforced and sliders to fix the board to the wall.
Type 2: for compost tunnels with a spigot floor, max. 8.5 m. Similar to type 1, but reinforced and in different parts. A galvanised tube to support the boards at the higher level and with sliders is part of the supply. At the rear of the tunnel the board has a foot plate of heavy duty galvanised steel as backing for discharging the last bit of compost with a front loader.
