The present invention provides a nursing bottle cooling device capable of cooling milk accommodated in a nursing bottle down to a proper temperature without using hands, in which the original temperature of the milk is higher than the proper temperature. The nursing bottle cooling device includes: a cooling tank which accommodates a cooling medium for cooling the nursing bottle； a rotary supporting device which rotatably supports the nursing bottle by an angle relative to horizontal direction in such a way that at least a pacifier of the nursing bottle does not contact the cooling medium in the cooling tank； and a rotary driving device which allows the nursing bottle rotatably supported by the rotary supporting device to rotate about a longitudinal axis thereof.本發明提供一種哺乳瓶冷卻裝置，其不藉由人手便可將收容於哺乳瓶中之比合適之溫度高之溫度的奶冷卻至合適之溫度。該哺乳瓶冷卻裝置包括：冷卻槽，其用以收容將哺乳瓶冷卻之冷卻介質；旋轉支持器件，其以哺乳瓶之至少奶嘴部分不與冷卻槽內之冷卻介質接觸之方式，將哺乳瓶在相對於水平形成角度之狀態下可旋轉地加以支持；以及旋轉驅動器件，其用以使由旋轉支持器件可旋轉地支持之哺乳瓶繞其縱軸線旋轉。
