Clams are popular, how can heat pump dryers help the development of the industry?

With the continuous improvement of the national economic level, seafood and aquatic products have gradually become frequent customers on consumers' tables, and the consumption has been rising. In this context, the shellfish aquatic products represented by clams provide a new path for the revitalization of local villages and the increase of villagers' income. Large-scale clams industries have emerged in various places, and the industrial chains of clams breeding, fishing, and processing have been accelerated. In order to meet the needs of mass production, we can also see that machinery such as drying equipment is gradually put into use in production.

There are four major sea areas in my country, which are rich in various seafood and aquatic products such as sea cucumber, abalone, squid, blue crab and mussels. Thanks to the improvement of people's consumption level in recent years and the accelerated construction of infrastructure such as cold chain logistics, the residents in coastal areas and inland cities have undergone quantitative and qualitative changes in seafood consumption. The variety of seafood is becoming more and more abundant, and the quality is getting better and better.

With the increasing consumption of seafood, in addition to the harvest brought by fishing at sea, my country's seafood aquaculture industry has also grown rapidly. Among them, the aquatic products represented by razor clams have become a fragrant pastry with their own "different" attributes, and the scale of razor clams farming in Ninghai, Zhejiang, Fuqing, Fujian and other places is growing day by day.

To say that razor clams are "different", their shells are narrow and slender, razor-shaped, and known as "Xishi tongue", which is very different from the conventional shellfish in people's impressions. Liang Shiqiu once said in his collection of essays that "Xishi tongue belongs to shellfish, it is small and small like a clam, but not a mussel; the water pipe is long and white, often sticking out of the shell, and its shape is like a tongue; taste the tongue of Xishi. , don’t be surprised to be delicious” and so on.

When razor clams enter the consumer market, in addition to fresh food, dried razor clams are also a major form of consumption. It is said that the dried razor clams are egg yolk in color, thick in flesh, and rich in nutrients such as protein and vitamins, making them delicious. At the same time, after postpartum processing and polishing, the price of dried razor clams can reach market performance ranging from tens of yuan to hundreds of yuan per catty, which is also of great significance to increase its added value and increase industrial income.

It is worth mentioning that in the context of consumption upgrades, razor clams have gradually begun to transform into mechanized processing in large-scale farming in recent years. For example, the introduction of dryers has replaced traditional sun drying and air-drying, bringing a kind of Brand new production mode. It is understood that heat pump dryers are currently used for razor razor drying.

As we all know, heat pump drying adopts closed cycle drying, and parameters such as temperature, humidity and drying time can be adjusted according to material processing requirements. It has the advantages of good drying quality, high efficiency and energy saving, and is not easy to produce pollution. There are many applications. When heat pump drying equipment is applied to the processing of clams, clams are often first dried at about 50 and 60 °C in the first pass to reduce their moisture content to a certain level, and then refrigerated (or natural environment) to store them to regain moisture. After that, dry it again. After layers of drying, the finished dried razor clams can also change the disadvantages of traditional drying such as rough texture and poor appearance, and have been upgraded in terms of color and fragrance.

In recent years, the consumption of seafood and aquatic products has shown a good development trend, which is a big opportunity for the upstream industry. Through the upgrading of production and processing, driving the quality and efficiency of products to improve is the key to promoting razor razor products to seize the market. The upstream production entities should pay attention to the development trend of applicable machinery and equipment in a timely manner, accelerate the conversion of new and old kinetic energy, and enhance the market competitiveness of products. .
