Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a freezing device that continuously freezes products to be frozen.

[Conventional technology]

Fig. 3 shows a conventional freezing device. In the figure, 1 is a hollow cylindrical rotary plate that is installed horizontally and has a cold brine 2 sealed inside. An annular tube 3 formed of a flexible sheet in which brine 2 is enclosed; 4 a shaft rotated by a drive device 5; 8 is a frozen product, and 9 is a bolt that fixes the divided rotary plate 1 together.

Next, the operation will be explained. A cold brine 2 cooled by a heat exchanger (not shown) is introduced into the rotating plate 1 and the annular tube 3. The rotary plate 1 and the annular tube 3 whose inner peripheral portions are fixed to the shaft 4 rotate simultaneously as the shaft 4 rotates. The guide 6 curves upward at one point on the circumference and lifts up the outer edge of the annular tube 3 to form an opening.

The product 8 to be frozen is placed on the rotary plate 1 through this opening, frozen from both sides by the cold brine 2 in the rotary plate 1 and the annular tube 3, and taken out from the opening by one rotation of the rotary plate 1.

[Problem that the invention attempts to solve]

Conventional freezing equipment is configured as described above, so when placing the items to be frozen on the rotary plate, the location where the cold brine is enclosed is unknown, resulting in insufficient freezing depending on the placement position. It was hot.

This invention was made in order to solve the above-mentioned problems, and the purpose is to obtain a freezing device that can clearly indicate the placement position of the items to be frozen and freeze them sufficiently.

[Means for solving problems]

The freezing device according to this invention has a step provided on the upper surface of the rotary plate along the circumferential direction at the freezing effective limit position in the radial direction.

[Effect]

In the freezing device according to this invention, a step is provided on the surface on which the products to be frozen are placed at approximately the same position as the position where the cold brine is enclosed, thereby clearly indicating the effective freezing surface of the products to be frozen.

[Example of idea]

An embodiment of this invention will be described below with reference to the drawings. In FIGS. 1 and 2, reference numeral 10 denotes a step 11 provided on the upper surface of the rotating plate 1 in a radial direction along the circumferential direction at approximately the same position as the sealing position of the internal cold brine 2.
is the freezing effective surface. Note that the other configurations are the same as the conventional one, so explanations will be omitted.

Next, the operation will be explained. The product 8 to be frozen is placed on the effective freezing surface 11 on the rotary plate 1, which rotates in the same manner as in the prior art. The rotary plate 1 has a step 10 indicating the effective freezing limit position to distinguish the outer edge and the inner edge, which are insufficiently frozen, so that the mounting location becomes clear.

In the above embodiment, the annular tube 3 in which the cold brine 2 is enclosed is used as the upper cooling means, but cooling means such as cold air blowing may be used, and the same effects as in the above embodiment can be obtained.

[Effect of idea]

As described above, according to this invention, since a step is provided on the surface of the rotary plate on which the items to be frozen are placed so as to clearly indicate the effective freezing surface, there is an effect that the items to be frozen can be frozen evenly and sufficiently.

[Brief explanation of the drawing]
