PROBLEM TO BE SOLVED: To provide a gas hydrate pellet molding device by which a gas hydrate pellet is efficiently formed by performing a dehydration step in a gas hydrate-forming plant and a molding step of the GH pellet in a single device. SOLUTION: A compression plunger 21e is disposed in an inner cylinder 21a of a compression chamber 21, a GH slurry supplied to the inner cylinder 21a is squeezed by advancing the compression plunger 21e and water draining is performed from a screen part 21c provided in a part of the inner cylinder 21a. A gate valve 22 is opened after water squeeze, the compression plunger 21e is advanced and passed through the gate valve 22 and the GH pellet P is extruded and moved to a cooling chamber 23. The gate valve 22 is closed to cool the cooling chamber 23, the compression chamber 21e is made to retreat and a next GH slurry is supplied. After cooling in the cooling chamber 23, a valve body 24a is rotated to supply the GH pellet P received in a holding chamber 24c to a supplying passage 25 for supplying the GH pellet P to a depressurizing step.
