Drying Technology of Sea Cucumber and Selection of Sea Cucumber Dryer

- May 07, 2019 -

The nutritive value of sea cucumber is very high, but drying is very important. The traditional drying process can provide better nutrition, but there are certain deviations in color and quality. The most important thing is to rely on the weather. If the weather is bad, the drying efficiency will be greatly reduced. Therefore, sea cucumber dryer plays an important role in the drying process of sea cucumber. The water content of

sea cucumber is very high, generally above 90%, while that of dried sea cucumber is generally 3%, so more than 30 jin of wet sea cucumber can get 1 kg of dried sea cucumber. This makes sea cucumbers particularly expensive. In order to increase the output of sea cucumber after drying, some businesses adopt the process of soaking and drying with sugar or salt, which can double the output, but the quality and nutrition after drying are greatly reduced.

Generally speaking, the nutrient content of salted dried sea cucumber is less than 10%, but the output doubles. Even if the price is reduced a little, the seller can get a higher profit. Sugar-dried sea cucumbers are dark and have beautiful parameters and a sweet taste. The advantage is beautiful, but the disadvantage is more obvious. Sugar-dried sea cucumber is relatively humid and can not be stored for a long time. At the same time, its rising rate and taste are not as good as light-dried sea cucumber. Adding sugar is not conducive to the consumption of diabetic patients. There are many drying methods for

sea cucumbers. The most primitive method is to air-dry, which usually takes 10 days to obtain high quality sea cucumbers. If the weather is bad, the drying time will be longer.

There is also a hot-air oven-type sea cucumber dryer. Hot-air oven is a traditional drying technology, which gradually takes water away from the outside to the inside of sea cucumber through the continuous blowing of hot air. Generally speaking, a drying cycle is about 2-3 days. This is a relatively economical drying method, the drying cycle is not long, the drying effect is good, the most important thing is that the equipment is cheap and easy to start.

Finally is the high-end drying process, hot air+microwave dual-process sea cucumber dryer. Microwave can directly act on the interior of the material, through the role of polar molecules to generate heat from the interior, drying from the interior of sea cucumber, while hot air is the exterior drying, while controlling the temperature and humidity inside the equipment to ensure a perfect drying shape. The advantages of microwave + hot air are quick drying, high output, good quality after drying and no loss of nutrients, but the cost of equipment is high, which is suitable for enterprises with high requirements for products.
