Embodiment 1

[0020] see figure 1 , a cold air drying method for aquatic products, the cold air drying method for aquatic products comprises the following steps:

[0021] S1: Baking: Drain the cleaned aquatic products after cleaning and treatment. The draining time is controlled at 4.5 minutes, and then the aquatic products are hung in a heat-insulating and airtight drying room for baking. The temperature of the drying room is controlled at 42 degrees Celsius. Set the water content detection interval of aquatic products;

[0022] S2: Circulation ventilation: adopt high-efficiency fans to force circulation ventilation, and the wind speed of the fans is controlled at 3 m / s, so that convective negative pressure is formed in the drying room;

[0023] S3: Cold air circulation: Imported air cooler is used to feed cold air into the drying room. The total power of the air cooler is 18.7kw / h, the temperature range is 10-35 degrees Celsius, the wind speed range is 0-12m / s, and the air volume is 1000...

Embodiment 2

[0027] see figure 1 , a cold air drying method for aquatic products, the cold air drying method for aquatic products comprises the following steps:

[0028] S1: Baking: Drain the cleaned aquatic products after cleaning and treatment. The draining time is controlled at 4 minutes, and then the aquatic products are hung in a heat-insulating and airtight drying room for baking. The temperature of the drying room is controlled at 35 degrees Celsius. Set the water content detection interval of aquatic products;

[0029] S2: Circulation ventilation: adopt high-efficiency fans to force circulation ventilation, and the wind speed of the fans is controlled at 2 m / s, so that convective negative pressure is formed in the drying room;

[0030] S3: Cold air circulation: Imported air cooler is used to feed cold air into the drying room. The total power of the air cooler is 18.7kw / h, the temperature range is 10-35 degrees Celsius, the wind speed range is 0-12m / s, and the air volume is 1000m ...

Embodiment 3

[0034] see figure 1 , a cold air drying method for aquatic products, the cold air drying method for aquatic products comprises the following steps:

[0035] S1: Baking: Drain the cleaned aquatic products after cleaning and treatment. The draining time is controlled at 5 minutes, and then the aquatic products are hung in an insulated and airtight drying room for baking. The temperature of the drying room is controlled at 50 degrees Celsius. Set the water content detection interval of aquatic products;

[0036] S2: Circulation ventilation: adopt high-efficiency fans to force circulation ventilation, and the wind speed of the fans is controlled at 5 m / s, so that convective negative pressure is formed in the drying room;

[0037] S3: Cold air circulation: Imported air cooler is used to feed cold air into the drying room. The total power of the air cooler is 18.7kw / h, the temperature range is 10-35 degrees Celsius, the wind speed range is 0-12m / s, and the air volume is 1000m 3 , ...

Abstract

The invention discloses an aquatic product cold air drying method in the technical field of aquatic product processing. The aquatic product cold air drying method is characterized by comprising the steps of: (S1) baking; (S2) circular ventilation; (S3) cold wind circulation: cold wind is fed in a baking room by an imported wind cooler; and under a continuous effect of the imported wind cooler and a high-quality control system, the cold and hot wind speeds in the baking room are alternated until the water content of an aquatic product is 30-40%; (S4) drainage; and (S5) tempering and drying. In the insulation closed baking room, the efficient fan is used for forced circular ventilation to form convection negative pressure; under the continuous effect of the imported wind cooler and the high-quality control system, the cold and hot wind speeds in the baking room are alternated; when the cold wind performs circular convection, the surface temperature of the aquatic product rises; and compared with a traditional method, the aquatic product cold air drying method has the advantages of short machining time, low machining efficiency, increment of the average dryness, saving of the energy consumption, simple operation and low cost.

Description

technical field [0001] The invention relates to the technical field of aquatic product processing, in particular to a cold air-drying method for aquatic products. Background technique [0002] Dried aquatic products are a large category of products in the processing of aquatic products. It not only solves the problem of preservation of aquatic products, but also the unique flavor of dried aquatic products is favored by many consumers, such as squid, which contains many essential nutrients necessary for human body. A variety of amino acids, protein and other nutrients, the meat is delicious and tender, often made into dried squid. At present, the drying of aquatic products usually adopts natural drying or boiler steam or electric heating to make the temperature rise and dry at high temperature. Natural drying is limited by the climate, the quality is difficult to control, labor-intensive, low-efficiency, and not convenient for large-scale production. It is easy to be pollute...
