Claims17
An installation for drying a biodegradable pot with thin walls for the growing of plants, which installation comprises a drying mold, a wall of which has a shape adapted to a corresponding shape of a wall of a molded pot to be dried, and means for heating the wall of the drying mold at a temperature above 160° C., and preferably between 180 and 240° C.
An installation for manufacturing a biodegradable pot with thin walls for growing plants, which installation comprises:
- a molding die, a wall of which has a shape adapted to a corresponding shape of a pot to be manufactured, the wall of the molding die being made of a mesh material, and a suction means for sucking and pressing a liquid clay against the wall of the molding die,
- a transfer counter-mold, a wall of which has a shape adapted to a corresponding shape of a pot to be manufactured,
- a drying installation according to one of the preceding claims, wherein the wall of the drying mold is made of a solid material or an openwork material, a percentage of open area of which is at least twice smaller than a corresponding percentage of open area of the mesh material forming the wall of the molding die.
