[0022] The following are specific embodiments of the present invention, and the technical solution of the present invention is further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments, and the following embodiments do not limit the utility model involved in the claims. In addition, all combinations of the features described in the embodiments are not necessarily required for the solution of the utility model.

[0023] The principle and structure of the present utility model are described in detail below with reference to the accompanying drawings and embodiments.

[0024] Example

[0025] This embodiment is described with a flat plate quick freezer for plasma freezing. Plasma is usually quick frozen by a flat plate quick freezer. The flat plate quick freezer is a device for quick freezing of plasma. The device includes an upper freezing plate 3, a lower freezing plate 4 and a plasma tray 1. The space between the upper and lower freezing plates 4 is a freezing chamber. The plasma tray 1 is placed on the lower freezing plate 4. The plasma tray 1 is used to place a plasma bag 2. When freezing, the two freezing plates move toward each other, and the plasma is squeezed between the two freezing plates. After contacting the freezing plates, heat is directly exchanged to achieve the purpose of quick freezing. In actual application, due to the humidity of the environment or the wet surface of the plasma bag 2 to be frozen, the plasma bag 2 is sometimes adhered to the upper freezing plate 3, making it impossible to perform subsequent plasma quick freezing operations.

[0026] For this reason, Figure 1 , 2 As shown, a flat quick-freezing machine is proposed, comprising an upper freezing plate 3 and a lower freezing plate 4, wherein an anti-adhesive cloth 5 is arranged below the plate surface of the upper freezing plate 3, and the anti-adhesive cloth 5 is controlled by a retracting device to be retracted and released relative to the upper freezing plate 3, so that different areas of the anti-adhesive cloth 5 correspond to the plate surface of the upper freezing plate 3. During quick freezing, the upper and lower freezing plates 4 move toward each other, and the anti-adhesive cloth 5 is spaced between the blood bag and the upper freezing plate 3 to form a spacing layer, so that the blood bag is not in direct contact with the upper freezing plate 3, and the plasma bag 2 is prevented from being adhered to the upper freezing plate 3 due to environmental humidity or the surface of the plasma bag 2 to be frozen is wet. Since the anti-adhesive cloth 5 is thin, it does not affect the heat exchange between the blood bag and the upper freezing plate 3.

[0027] To improve the anti-sticking effect, the anti-sticking cloth 5 can be provided with an anti-sticking coating so that its surface has good anti-sticking properties. This helps prevent frozen food from sticking to the cloth during packaging and processing. To reduce the impact on freezing performance, the anti-sticking cloth 5 is preferably made of cloth with good thermal conductivity.

[0028] The anti-sticking cloth 5 is relatively retracted and released by the retracting and releasing device, that is, the anti-sticking cloth 5 has a longer length. The retracting and releasing device retracts and releases the anti-sticking cloth 5 so that different areas of the anti-sticking cloth 5 correspond to the plate surface of the upper freezing plate 3, so that different parts of the anti-sticking cloth 5 are spaced between the blood bag and the upper freezing plate 3 each time, thereby ensuring the anti-sticking effect of the anti-sticking cloth 5, that is, when one freezing is completed, the upper freezing plate 3 is separated from the lower freezing plate 4, and then the retracting and releasing device moves the anti-sticking cloth 5, so that a section of the anti-sticking cloth 5 that has been in contact with the blood bag and is located under the upper freezing plate 3 is moved away, and the other section of the anti-sticking cloth 5 is moved to the bottom of the upper freezing plate 3 to facilitate the freezing of the next plate of blood bags.

[0029] The retractable device includes a reel 6 for reeling the anti-sticking cloth 5, and the reel 6 rotates to reel the anti-sticking cloth 5 so that the anti-sticking cloth 5 passes under the upper freezing plate 3, that is, the reel 6 is used to control the movement of the anti-sticking cloth 5 relative to the upper freezing plate 3 by reeling the anti-sticking cloth 5. The retractable device of this embodiment includes two reels 6 respectively located on opposite sides of the upper freezing plate 3, and the two reels 6 are respectively used for retracting and releasing the two ends of the anti-sticking cloth 5, one of the reels 6 rotates to reel the anti-sticking cloth 5, and the other reel 6 rotates to release the anti-sticking cloth 5, so that the anti-sticking cloth 5 moves from one reel 6 to another reel 6, and the cloth moves relative to the upper freezing plate 3.

[0030] Also comprise the blowing device that is positioned at the side of described upper freezing plate 3, the blowing device is for example a hair dryer 7, and described blowing device blows air on the described anti-sticking cloth 5 that moves out from described upper freezing plate 3 below, so that described anti-sticking cloth 5 keeps dry, so that use next time.Between each described reel 6 of the present embodiment and described upper freezing plate 3, be provided with the air blowing port of described blowing device.In order to improve air-drying speed, described blowing device can be a hot air hair dryer 7 that can blow hot air.

[0031] The invention also includes a blocking device, which includes a blocking body 8 located on the side between the upper freezing plate 3 and the lower freezing plate 4, and the blocking body 8 is located below the anti-sticking cloth 5. The lower freezing plate 4 can push the blocking body 8 upward, so that the blocking body 8 blocks the lateral gap between the upper freezing plate 3 and the lower freezing plate 4, so as to prevent the cold air in the freezing chamber from leaking out from the gap between the upper freezing plate 3 and the lower freezing plate 4 when the plasma is frozen, thereby improving the freezing efficiency. The blocking body 8 can be, for example, a flexible body with heat preservation performance such as a heat preservation curtain or heat preservation cotton.

[0032] The blocking body 8 is arranged on the supporting body 9, and the supporting body 9 is arranged on the upper freezing plate 3 through a retractable floating supporting structure. When the floating supporting structure is extended, a gap is provided between the blocking body 8 and the upper freezing plate 3 for the anti-adhesion cloth 5 to pass through. The size of the gap is set to allow the anti-adhesion film cloth to pass freely, so that the anti-adhesion cloth 5 can move smoothly, avoiding the blocking restriction of the anti-adhesion cloth 5 by the blocking body 8. The floating supporting structure can be, for example, a spring 10. When the upper freezing plate 3 and the lower freezing plate 4 are close to each other, the blocking body 8 is pressed to overcome the supporting force of the spring 10, so that the blocking body 8 is squeezed between the upper freezing plate 3 and the lower freezing plate 4, so as to achieve the sealing of the side between the upper freezing plate 3 and the lower freezing plate 4.

[0033] Specifically, the support body 9 can be a heat-insulating cotton, which is connected to the bracket 11, and the bracket 11 is connected to the upper freezing plate 3 through the floating support structure, and the floating support structure is a spring 10. The heat-insulating cotton can not only be deformed but also has certain supporting performance, and can be used as a stopper 8 or as a support body 9 connected to the bracket 11.

[0034] After the plasma freezing operation is completed, the upper freezing plate 3 is automatically separated from the lower freezing plate 4. Under the action of the spring 10, the baffle 8 and the upper freezing plate 3 are separated by a certain distance so that there is a gap between the baffle 8 and the upper freezing plate 3 for the anti-sticking cloth 5 to pass through. Then, the reel 6 is rotated to remove a section of the anti-sticking cloth 5 that has just participated in the plasma freezing operation and replace it with an adjacent section of the anti-sticking cloth 5. During the removal process, the fan blows air to the anti-sticking cloth 5 below it to keep its surface dry for next use. The anti-sticking film cloth can move left and right between the lower surface of the upper freezing plate 3 and the upper surface of the heat preservation enclosure to prevent the plasma bag 2 from adhering to the upper freezing plate 3.

[0035] The insulation enclosure is a part of the plate freezer. Its function is to reduce the loss of cooling energy during the freezing process, improve freezing efficiency, and prevent the impact of the external environment on the freezer. The insulation enclosure is usually made of insulation materials, such as polyurethane foam, polystyrene, etc., which have good thermal insulation performance, can effectively reduce the loss of cooling energy during the freezing process and improve energy utilization efficiency. The insulation enclosure can serve as the outer protective layer of the plate freezer to prevent the impact of the external environment on the freezer, thereby protecting the normal operation of the freezer. The insulation enclosure can reduce the frost on the surface of the freezer, help keep the freezer clean, and extend the service life of the freezer. By reducing the loss of cooling energy, the insulation enclosure can improve the freezing efficiency of the plate freezer, shorten the freezing time, and improve production efficiency. The insulation enclosure is usually easy to clean and maintain, and can be cleaned regularly to ensure its good thermal insulation performance and maintain the hygienic state of the freezer.

[0036] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described, or replace them in similar ways, without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
