Provided is a conveying device used under a condition having a large pressure difference which is observed during a process such as a depressurizing process in an operation of manufacturing gas hydrate pellets and a method of controlling the same, the conveying device requiring less ancillary facilities, being small in size, and achieving high-speed processing while achieving secure blockage of pressure. The conveying device 1 includes: a casing 15 including a spherically-formed valve chamber in a center portion thereof which has one side connected to a high-pressure pipe 21 on a high-pressure side and another side connected to a low-pressure pipe 22 on a low-pressure side; a spherical valve 11 rotatably supported inside the casing 15; a gap section 16 which is a gap formed between the casing 15 and the spherical valve 11; a high-pressure-side seal 13 which seals the high-pressure pipe and the gap section 16 from each other; and a low-pressure-side seal 14 which seals the low-pressure pipe 22 and the gap section 16 from each other, the conveying device 1 conveying, with rotation of the spherical valve 11, an object to be conveyed which is housed in a conveying chamber 12 formed by boring a portion of the spherical valve 11, the conveying chamber 12 including an opening 23 which corresponds to the high-pressure pipe 21 or the low-pressure pipe 22.
