During the construction of facilities for the pasteurization of substrate mycelium and germination in boxes or containers (or portable racks, shelving unit) is primarily determined by the size and the required number of these vessels, as well as how to install them in the foot . Between the rows of feet (piles) leave room 0.5 - 0.8 m, the distance between the top of the stack andoverlapping areas should be at least 1 m . Containers are set so that between them there was little space for air circulation .

Room equipped with a ventilation system provides fresh or recirculated air (or mixtures) - 250 - 300 m3 / h at 1 msubstrate . The minimum pressure of 600 Pa (60 mm of water . v . ) . The ventilation system includes a ventilation shaft with a device for cleaning the air of particles larger than 3 microns, valves for controlling the ratio of fresh and recirculated air, cooler air, (especially important for the southern regions with hot summers) steam supply at the rate of 6 -7kg / (vx Xm), distributing supply air duct and channel sampling of indoor air, mine ventilation . The fan is mounted behind the mixing chamber of fresh and recirculated air.

Fresh air or in admixture with recycle serves to regulate the temperature of the substrate and the substrate microflora oxygen supply . Using recirculated air having a high moisture content avoids excessive drying of the substrate and significantly reduce moisture loss .
