- 被凍結物に低温液化ガスを接触させて急速凍結させて凍結物とする急速凍結装置において、前記被凍結物を収容する凹部を備えたトレイと、該トレイを支持して水平方向に搬送する搬送手段と、該搬送手段の搬送方向上流側で、前記凹部内に前記被凍結物を収容した前記トレイを前記搬送手段に支持させた状態で前記凹部内に前記低温液化ガスを液体状態で供給する低温液化ガス供給手段と、前記搬送手段の下流側で、前記低温液化ガスによって急速凍結された前記凍結物を前記凹部内から回収する凍結物回収部とを備え、
前記低温液化ガス供給手段は、前記低温液化ガスを前記凹部内に液面を形成するように被凍結物を急速凍結するのに必要十分な量に調節して供給する自動開閉弁を備え、
前記低温液化ガス供給手段の下流側で、かつ、前記凍結物回収部の上流側に、前記搬送手段で搬送される前記トレイの上面を覆う蓋板を備え、前記トレイの上面と前記蓋板の下面との間に低温ガスを保持する隙間を設けている急速凍結装置。 - 前記トレイは、前記凹部を複数個備えている請求項1記載の急速凍結装置。
- 前記トレイは、前記搬送手段に着脱可能に載置される請求項1又は2記載の急速凍結装置。
- 請求項1乃至3の急速凍結装置を用いた急速凍結方法において、
前記自動開閉弁の開弁時間を調整することにより、低温液化ガスの供給量を調節し、被凍結物を急速凍結するのに必要十分な量の低温液化ガスを凹部に液面を形成するように供給することを特徴とする急速凍結方法。
