  • Patent number: 4967488
    Abstract: The invention relates to a method of picking up, carrying, drying and dry-keeping baled goods, and to a container as well as to a structure replacing a drying-house for carrying out the method. The most important application is the production of dry hay, which is effected by loading the hay bales in containers (1) to be ready for drying, said containers being provided with a meshed floor, high solid walls and removable roof. A structure replacing a drying-house is set up by mounting such loaded containers upon drying-air blowing gutters and, after drying or after temporary storage at the producer's, the same containers together with dried bales are carried to consumers to serve as covered storage spaces from which baled goods is gradually picked up for use. This is to eliminate expensive drying and storage buildings, to ensure high quality for dry hay, and to minimize unloading and loading.
