This Sterilizer works automatically on tracks in greenhouses and tunnels, sterilizing soil at different profondity from 10 to 20 cm covering the whole width of the tunnel (usually from 5 up to 8 m).
The working operation starts at the beginning of the greenhouse – first the operator has to set up the machine, then it works automatically with intermittent movements – its plate get stuck to the soil (plate is 1.5 m long, so it moves 1.5 m forward each step).
The time the machine stays in the sterilizing position is adjustable in order to give sterilization at different dephts (i.e. the longer the steam injection lasts, the deeper the soil is sterilized).
 

At the end of the treatment in the first position, the plate lift a few centimetres, moves on 1.5 m and the cycle starts again. There is an electronic system controlling the centiring and movement of the course, it drives the tracks during work by referring to the greenhouse structure.
At the end of the greenhouse the machine stops automatically.
Moreover there is a security system with a frontal barrier which stops the machine in case there are obstacles in the front.
The machine works with gas which is stored under the machine, while the water needed to produce steam is taken trough a pipeline attached to the machine, which has to be connected to the fixed water system.
The real success of this type of machine lies in the fact that it can sterilize soil infected with fungi, nematodes and infesting weed seeds just with steam, which is the most eco friendly way, in the maximum respect for environment.
The working system is very rational in the sense that the machine works on the soil before it is crushed by the machine, thanks to its frontal plate, granting a perfect sterilization homogenity without useless steam leakage in the tracks.
Since the machine compaction is very slight (0.37 kilos/square cm) , the following operation of transplanting does not need further soil preparation.
Steam comes out at 200° c so the soil fairly dry (see the brochure for technical details)
