Double-belt press

A double-belt press that applies pressure to a product by means of a pressurizing fluid contained in a pressurizing chamber while conveying the product sandwiched between a pair of belts, the double-belt press comprising:

• a sealer that is provided along an outer edge of the pressurizing chamber and seals the pressurizing chamber,
• wherein the sealer includes
• an inner seal that is contained in an inner sealing groove and accommodates an inner seal flow passage having an intake port via which a sealing fluid supplied into the inner sealing groove is taken in and a jet port via which the sealing fluid taken in via the intake port jets toward the belts, the intake port and the jet port being formed at opposite ends of the inner seal flow passage,
• an outer seal that is contained in an outer sealing groove provided at a position farther from the pressurizing chamber than the inner sealing groove and accommodates an outer seal flow passage having an intake port via which the sealing fluid supplied into the outer sealing groove is taken in and a jet port via which the sealing fluid taken in via the intake port jets toward the belts, the intake port and the jet port being formed at opposite ends of the outer seal flow passage, and
• a partition wall that is formed between the inner sealing groove and the outer sealing groove and has a plurality of fluid supply passages that supply each of the inner sealing groove and the outer sealing groove with the sealing fluid and a plurality of fluid recovery passages that recover the sealing fluid accumulating in a space formed between the inner seal and the outer seal, the fluid supply passages and the fluid recovery passages being provided in positions different from one another in a direction along the outer edge of the pressurizing chamber.
