Claims

[Scope of utility model registration request]

A rotary plate provided horizontally, a lower cooling means for cooling the rotary plate from the lower surface, an upper cooling means disposed on the upper surface facing the rotary plate, and a drive device for rotating the rotary plate. In the freezing device, the item to be frozen is placed on the rotary plate and frozen from both upper and lower surfaces, and a step is provided on the upper surface of the rotary plate at a freezing effective limit position in the radial direction along the circumferential direction. A freezing device characterized in that a freezing effective limit position surface is held at a level difference lower than the upper surface of other rotary plates.
