It is well known that the technological trends of aquatic product drying dehumidifier and green intelligent drying equipment are greatly affected by the weather and natural environment. The traditional aquatic product drying can only be naturally dried in a dry, windy and sunny weather for 5-7 days. During this period, special personnel are also required to watch over the drying on site. Even so, in the natural environment, it is impossible to completely avoid dust and fly pollution. In case of overcast and rainy days, the moisture in the air is heavy, and the aquatic products cannot be dried in time, they will also face the risk of deterioration, which will bring incalculable losses to fishermen and fishery production enterprises
The drying and dehumidification theory of aquatic products:
2. There is a large amount of dust in the drying room, and the finished product is dark in color
3. The coal needs to be changed in the midway, so the labor intensity is high
4. Sulfur dioxide, carbon dioxide, coal ash, etc. are produced in large quantities during the drying process, and the working environment is harsh
5. The coal flue gas has seriously corroded the equipment in the drying room, and its service life is short
6. It fluctuates greatly, affecting the drying quality
II. Problems to be paid attention to in the drying of aquatic products
2. Humidity - the general water content of aquatic products is relatively large. Therefore, controlling the moisture discharge is an important factor to determine the drying quality
In addition, because the water of aquatic products exists in fats and oils, dehydration is difficult, and the control of dehydration speed is critical
3. Time - the drying cycle of aquatic products is generally long, and rapid drying will generally damage the drying quality
4. Color - it is very important to maintain the color of aquatic products after drying
5. Air volume - the drying of aquatic products generally requires a large circulating air volume, and the wind speed is also relatively high to avoid water vapor staying on the material surface
III. Temperature and humidity control in the drying process of aquatic products
During dehumidification, the drying temperature shall be controlled between 43-45 ℃, the drying shall last 15-20 hours, and the humidity shall be controlled between 60-70% RH
The temperature of the sizing shrinkage section is reduced to 36-38 ℃, and the drying lasts for 10-12 hours. The humidity is controlled at about 50% RH
In the final stage, the temperature shall be controlled between 50-55 ℃, the drying time shall be 7-8 hours, and the humidity shall be controlled at about 20% RH, until the product reaches the best drying effect, the machine shall be shut down, and ventilation and cooling can be used
The whole drying process takes about 48 hours
Used in aquatic product drying room_ G aquatic product drying dehumidifier and Parkoo series heating, drying and dehumidifying integrated machine are not subject to seasonal restrictions and can realize continuous production throughout the year without being affected by the weather; Simulate the principle of natural air drying, and adopt the medium and low temperature drying technology. After drying, the fish products have uniform dryness, excellent color quality, high product grade and no pollution, and can be stored for a long time; The drying system is fully intelligent, automatic and unattended, which can achieve accurate temperature and humidity control; Adopt closed drying mode to save operation cost; No waste gas and heat emission, no noise pollution, energy conservation and environmental protection. At the same time, different drying schemes can be designed according to different capacity and energy structure of users
_ G aquatic product drying dehumidifier and Parkoo series heating, drying and dehumidifying integrated machine can not only quickly remove the moisture in the drying room, effectively control the humidity in the drying room during the whole drying process, but also can select the corresponding power of electric heating to assist the temperature rise, so as to greatly accelerate the drying speed, effectively improve the utilization rate of the drying room and the drying quality! You can inquire the details of aquatic product drying dehumidifier and green intelligent drying equipment_ Technical parameters of G aquatic product drying dehumidifier and Parkoo series heating heating drying dehumidifier:
Project address: Zhanjiang aquatic product
Project name: aquatic product drying
dehumidification area: total indoor area of 30 m2, floor height of 2.6m
Scheme design: 1. Equipment selection: 2 sets_ GS heating type aquatic product drying dehumidifier, with a dehumidification capacity of 10kg/h and a maximum temperature of 50 ℃
2. Design description: The equipment is a movable guide wheel, which does not need to be installed. It can be placed anywhere. It can be connected to a hose for automatic drainage. If space is needed, the equipment can be placed outdoors and connected to the air inlet and outlet for use. (If the ambient temperature is higher than 50 ℃, it is recommended to install it outdoors)
To sum up, the drying of aquatic products requires low temperature and strong wind, such as fish, shrimp, crab, shellfish, turtle, frog, etc. The drying cycle is large to avoid high temperature affecting the product quality after drying. Aquatic products have a large water content. Controlling the moisture discharge is an important factor to determine the drying quality. In order to ensure the good appearance and luster of aquatic products after drying, it is necessary to use_ G aquatic product drying dehumidifier and Parkoo series heating, drying and dehumidifying integrated machine are used for scientific and reasonable dehumidification, so as to avoid water vapor staying on the material surface and prevent bacterial growth. All the technical trends of the above aquatic product drying dehumidifier and green intelligent drying equipment are provided by the electrical appliances for your reference only
