Embodiment 1

[0019] This embodiment proposes a method and device for thawing frozen aquatic products with fast thawing speed and good thawing effect.

[0020] The frozen aquatic product thawing method of the present embodiment comprises the steps:

[0021] A. Soak the frozen aquatic products in cold water at 2-8°C, and take the frozen aquatic products out of the cold water after an ice layer forms on the surface of the frozen aquatic products;

[0022] B, the ice layer on the surface of the frozen aquatic product is removed;

[0023] C. Repeat steps A and B until no ice layer appears on the surface of the frozen aquatic product. Finally, take the frozen aquatic product out of the cold water and let it thaw naturally at room temperature.

[0024] The principle of the above thawing method is as follows:

[0025] After putting the frozen aquatic product into cold water, it will absorb the heat in the water and cause an ice layer to appear on the surface, but during the above-mentioned freez...

Abstract

The invention aims to provide a frozen aquatic product unfreezing method and device capable of being high in unfreezing speed and good in unfreezing effect. The frozen aquatic product unfreezing device comprises a plurality of cold water basins and a plurality of vibration tables, wherein the cold water basins are connected with cold water supply equipment; the cold water basins and the vibrationtables are arranged in a spacing manner; an oblique conveyer belt is arranged between each cold water basin and the corresponding adjacent vibration table; one end of each conveyer belt is immersed inthe corresponding cold water basin, and the other end of each conveyer belt extends obliquely upwards to the upper part of a material inlet end of the corresponding vibration table; the table top ofeach vibration table is obliquely arranged; the sloping direction of each table top is gradually lowered from the feeding end to the discharging end of the corresponding vibration table; and each table top extends to a position above the corresponding conveyer belt in the corresponding cold water basin at the discharging end of the corresponding vibration table. According to the frozen aquatic product unfreezing device disclosed by the invention, the principle that cold water freezes and gives off heat, is adopted; the unfreezing device in an assembly line type is adopted, so that the situation that the unfreezing effect can be guaranteed, the unfreezing speed is greatly increased, and the frozen aquatic product unfreezing device has high practicality.

Description

technical field [0001] The invention belongs to the technical field of aquatic product processing, and in particular relates to a method and device for thawing frozen aquatic products. Background technique [0002] In order to prevent rot and deterioration, many aquatic products are frozen for storage and long-distance transportation, and must be thawed before processing. At present, the common thawing methods are generally natural thawing, soaking thawing, microwave thawing, etc. Among them, natural thawing and soaking thawing have the disadvantages of large area and long thawing time. Processing quality and taste. Contents of the invention [0003] The object of the present invention is to propose a method and device for thawing frozen aquatic products with fast thawing speed and good thawing effect. [0004] The frozen aquatic product thawing method of the present invention comprises the following steps: [0005] A. Soak the frozen aquatic products in cold water, and...
