CONSTRUCTION AND EQUIPMENT| OF MODERN COMPOST YARD
PRODUCTION OF THE COMPOST FOR MUSHROOM CULTIVATION
The first stage of the compost production process takes place outdoors, in the open air.Raw materials such as straw, dung manure, gypsum are used.They are laid in prisms on a concrete slab and moistened with technological water.All raw materials are machine-blended and re-wetted during this process.So prepared material is laid in prisms.It is important that this is done on a ventilated floor, as it uses air through the ventilation system to feed directly to the prism so that the fermentation takes place.Prisms are regularly overturned using the harvester.After a dozen or so days the material turns into a phase 1 compost.
Compost 1 must be transported to the tunnels.For this purpose a loader and conveyor with a special device for uniform distribution of material is used.Tunnels are aligned, heated, pasteurized and conditioned.In this way, the phase 1 compost is transformed after a one-week process into phase 2. The second phase substrate after addition of the mycelium can already be sent to customers.The part that is subjected to further processing and is incubated into phase 3 by incubation.
Phase 2 compost is transported from the tunnel by means of a conveyor to inoculate the mushroom mycelium.This process must be carried out with an acute hygienic regime.An infection from the outside can ruin the whole job.After this operation, the compost is transported to the next tunnel.Here it is re-aerated using fans.The incubation process takes about 2-3 weeks, when the mycelium is over the whole compost.Its color changes from brown to reddish.You see mycelium.In this form, the compost of phase 3 may already hit the mushrooms.
The entire construction process begins with the design of the investment, taking into account all the parameters that must be met to ensure the final effect of the amount of compost produced.The following figure shows an example of the construction of the composting plant.
Parameters Phase I
Total capacity of phase I - 5300 tons per week.
Boot weight silo - 6600 tons per week.
The total number of bunkers - 18 pieces.
The length of each of the bunkers - 45 m.
The width of each bunker - 8.8 m.
Parameters of phase II and III
Total yield of phase III - 3200 tons per week.
Total Phase II yield - 3600 tons per week.
Total number of tunnels - 68 pcs.
Each tunnel section - 43 m.
Width of each tunnel - 4 m.
Discharge of tunnel mass - 200 tons of phase III.
Communication lines providing the best logistics. Tunnels are designed in such a way as to maintain a good level of hygiene.
