The changes made recently in the processing of agricultural food products and the choice of users to increasingly focus on organic products or products that are particularly treated against bacteria, have brought out a truth always known: all the products of the earth carry with them bacteria environmental and dangerous pathogenic bacteria for which treatment is increasingly required..
However, the treatment can not be chemical in order not to fall from the pan into the embers, it must be bio and therefore things get complicated as the solutions are not many and heavily affect the processing and the relative costs.
We are being contacted by a major asparagus producer to tackle this problem: it is an important production (over 100,000 square meters of greenhouses) and the business is based on forced production, in greenhouses covered and ground heated with coils of plastic pipes that carry hot water, all to get products already in the first days of February.l treatment can not be chemical so as not to fall from the pan into the embers, must be bio and then things get complicated as the solutions are not many and affect heavily processing and related costs.
To study the intervention, we started from the analysis of the washing water and we immediately realized that the bacterial load was not the desired one, it was necessary a radical intervention of the processing.
At that point the property decided a radical change of the plant and passing from the proposals to the practice has modified the system by clearly subdividing the two phases: collection and cleaning of the product on one side, processing and washing on the other and in this phase installation of a bactericidal appliance on the rinse water supply pipe
