To provide a clathrate production apparatus and production method in which a generated clathrate does not fasten to a cooler and pipe arrangement or the like, and a clathrate can be stably produced.
A clathrate production apparatus 1 in which a host agent of a liquid phase and a guest agent of a gas phase are reacted to produce a clathrate includes: a cooler 4 in which at least one of the host agent and the guest agent is cooled so that a gas-liquid mixed phase fluid in which the host agent and the guest agent are mixed may be made an overcooling state; a venturi tube 6 in which the gas-liquid mixed phase fluid in an overcooling state is circulated; and a transportation apparatus 3 in which the gas-liquid mixed phase fluid is circulated in a contraction part 6B of the venturi tube 6 by acoustic velocity, wherein current velocity of the gas-liquid mixed phase fluid is made super acoustic velocity by an enlarged diameter part 6C of a downstream of the contraction part 6B to generate an impulse wave, thereby an overcooling state of the gas-liquid mixed phase fluid is cancelled to generate a clathrate.
