What are the seafood drying problems?

  At present, there are many kinds of seafood drying, and the market demand for seafood is increasing. Therefore, the quality of seafood drying is the top priority. The following is several important issues in the drying of seafood: 

• Temperature-The drying of seafood is generally required to be carried out at a relatively low temperature to avoid high temperature affecting the quality of the product after drying.
• Humidity-Generally the moisture content of seafood is relatively large. Therefore, controlling the amount of moisture discharged is an important factor in determining the drying quality. In addition, since the moisture of seafood is contained in fats and oils, dehydration is difficult, and it is critical to control the speed of dehydration. 
• Drying time-Generally seafood drying takes a long time, and fast-drying normally destroys the quality of drying control;
• Color--Maintaining the color of seafood after drying is very important;
• Circulating wind-The drying of seafood generally requires a larger circulating air volume, and the wind speed is also relatively high to avoid water vapor staying on the surface of the material.

What are seafood drying methods? 

  There are two drying methods: sun drying and mechanical drying. Each method has its advantages and weaknesses. Mechanical drying is widely used, and production is fast.
  Sun drying is a method of drying by using the sun and wind. The low drying cost is its biggest advantage. However, in addition to a larger drying area, the drying is easily restricted by meteorological conditions, which is its disadvantage. When the weather is bad, it is not easy to dry. Even if it is dried, the quality of the product will be affected, and the fish may even become spoiled. Therefore, the seasons with dry air and low temperature are the ideal conditions for sun exposure. The processing cost of the ordinary mechanical processing method is relatively high, but if the high-temperature heat pump dryer is used, the energy input can be effectively saved, and the market competitiveness of the product can be greatly improved. The high-temperature heat dryer is a hot air dryer, which can quickly dry the fish and increase the output per unit time. The drying process can be divided into the initial drying of the removal of water from the surface of the fish and the latter drying of the removal of the internal water of the fish. The initial drying should be controlled faster in the initial stage, and the drying process should not be too fast in the later stage, so that good quality products can be obtained by processing.

The principle of seafood dryer machine working:

    Baixin seafood dryer is composed of air energy high temperature heat pump dryer, which is suitable for drying all kinds of products. It can automatically control temperature and humidity. The structure of the drying room and the use of hot air are scientific and reasonable. The heating area of the materials in the drying room is even and the heat preservation effect is good. , The unit consumes less electricity, has lower operating costs, and does not require a large amount of labor input.

  Baixin air energy heat pump dryer uses the reverse Carnot principle. The refrigerant is compressed by the compressor to become high-temperature and high-pressure gas, enters into the heat exchanger through the pipeline, and then passes through the fan to remove the heat generated by the heat exchanger send it to the drying room to heat and dry the seafood products and other materials, so that the seafood products are dried, and the moisture is discharged from the moisture outlet. The dehumidification system has a heat recovery device, and the recovered heat is used to heat the fresh air, which can save 60%-70% of the fresh air preheating energy consumption.

The seafood heat pump dryer machine structure: 
 
Advantages of high-temperature heat pump seafood drying room:
1. The drying process fully meets the food hygiene requirements;
2. The cleanliness and sanitation in the cabinet are in good condition, and the finished product is bright and lustrous;
3. Fully automatic control, reducing labor and labor intensity;
4. No wastewater/exhaust gas/waste residue is generated during the drying process, which is green and environmentally friendly; the working environment is comfortable and good.
5. Long service life, low operating cost, and good economy;
6. The temperature and humidity are controlled automatically; the temperature and humidity fluctuate little during the drying process, and the drying quality is stable and reliable.
