Abstract

A process and equipment for disinfecting bulk foods or animal feeds on a ship are described. According to this process, either before beginning to fill the cargo hold or when beginning the loading operation, a fumigation system is placed in the cargo hold and includes line sections that extend from the loading hatch to the bottom of the hold and are provided with gas passages at least in the vicinity of the bottom of the hold, and after filling the cargo hold, the end of the fumigation system which projects cut of the bulk material is connected to a centrifugal fan and the preparation which releases the gas is placed on in the surface of the bulk material and the fan is turned on and the cargo hold is sealed so that it is airtight. By operating the fan, the gas is pulled out of the gas space above the bulk material and directed into the bulk material from the bottom through the fumigation system. The system according to this invention includes a fan which is connected to a number of line sections that are joined together, in which case the line section in the vicinity of the bottom of the cargo hold is provided with gas passages for the gas to escape into the bulk material.
