Solar fish dryer

Drying is a very widely used process in the food and agricultural product processing industry. Currently, solar energy is being applied and developed strongly in life. The reason is that solar energy is a clean and never-ending source of energy.

There are many industries that have used solar energy such as solar electricity, agricultural dryers, solar seafood dryers. Below, SUNSAY dryer will introduce you to the solar fish dryer .

SUNSAY’s solar fish dryer can dry a variety of dried fish, solar dried fish in a delicious, nutritious, and beautiful color. Solar fish dryer is also one of the drying methods that are being used a lot today.

Dried fish has long been a favorite specialty dish in the country, dried fish has a strong rustic flavor in the countryside. Dried fish dishes have a delicious, fatty taste of fish meat. The processing and drying of fish, which has been applied for many generations, is usually sun-dried.

To overcome the disadvantages of hygiene and food safety when drying fish in the sun. SUNSAY dryer has researched and launched a new and more modern drying method. It’s a solar fish dryer.

Structure of solar drying fish dryer

The solar dryer consists of the following main parts:

Heat collector

The heat collector has the function of collecting radiant heat from the sun, this heat is collected and used by the drying fan to circulate throughout the drying chambers. The solar dryer heat collector is made from a good heat capture/collector material.

The frame uses metal materials that are curved in a wavy shape to increase the contact area to help absorb more heat from the sun.

Drying chamber

The solar drying chamber is the area for storing the drying products. Contrary to the heat-collecting chamber, the drying chamber is made of good insulation to avoid heat loss through the housing.

In the drying chamber containing the trolley and on the body of the trolley, there will be drying trays, the dried products are arranged on the trays. The car and drying tray are made of durable 304 stainless steel and especially ensure food safety and hygiene.

Drying air convection system

Air convection system uses axial type industrial blower. This drying fan will help the heat source circulate evenly throughout the drying chamber and help the fish or agricultural products in the chamber dry evenly and faster. The blower draws in the soy air and brings the moist air from the product to the outside.

Heating system

The solar dryer heating system is made of resistive rods with fins. The heating system only uses auxiliary heating in cases where there is insufficient sunlight for drying.

The principle of solar fish drying machine

Solar drying technology uses heat from the sun’s radiant energy to dry fish and other drying materials such as agricultural products and fruits in the drying chamber. In addition, the solar dryer also uses extra electricity to run the drying fan and heat it up in the hours or days with little sunshine.

When sunlight hits the collector, the radiant heat enters the drying chamber and heats up the panels. This heat source will be retained in the drying chamber so that the air in the drying chamber also heats up and does not escape under the greenhouse effect.

Hot air will be circulated by the convection fan throughout the drying chamber and circulated through the drying trays containing fresh fish. The moist air after being removed from the product will be sucked out through the outlet channel on the drying chamber.

Advantages of solar dryers

• The advantage of this method is that it is environmentally friendly, taking advantage of natural clean energy sources.
• Saving energy consumption, thanks to the use of energy from the sun.

Disadvantages of solar dryers

• The disadvantage of the solar drying method is that it must be placed outdoors in a sunny place.
• Large size, bulky compared to other dryers using solar collectors.
• Depends heavily on the weather, only good sunny hours can dry well.
• The operator must enter the drying chamber with high temperature, affecting health.

What is the temperature of the solar fish dryer?

When the weather is good, clear and sunny, the dryer’s thermal efficiency is the highest and the drying of fish with a solar fish dryer is the best, most beautiful and most effective. At that time, the average temperature in the dryer can be up to 60 – 70 degrees Celsius.

Depending on the simple or complex design of solar fish dryers, solar fish dryers will be fitted with more or less solar heat collectors. Due to price competition, solar fish dryers usually only install enough heat collection area according to the basic capacity. You can request additional options to increase the efficiency of heat collection.

Dry fish by traditional methods

In recent years, customers’ demand for dried fish is increasing and the requirements are higher for quality and production capacity. Meanwhile, the production capacity of the facilities has not been improved, supply is not enough demand. The facilities have expanded the area of ​​​​the drying yard, increased working hours, but still cannot meet the needs of customers.

On the other hand, the drying stage of dried fish processing facilities is highly dependent on the weather. In rainy days, facilities stop production, even damage the fish that are drying because of mold. That causes great economic damage and affects the reputation and business. Limitations of the traditional method of drying fish:

• Long drying time, hard fish meat, loss of sweetness, tough. Thereby, reducing the quality and nutrient content of the fish.
• At night or when it rains, it becomes more difficult to dry fish, leading to products that are prone to mold and spoilage.
• Traditional drying requires a large drying yard space.
• It takes a lot of labor because it has to be rotated frequently to dry evenly on both sides.
• Failure to ensure food hygiene and safety due to the effects of rainy weather or dusty, insectivorous environments.
• Inhomogeneity in fish quality after sun exposure.

Besides, exposure to direct sunlight is prone to dust, flies, and flies clinging to. Affecting product quality and food safety and hygiene is not guaranteed. At the same time, it takes a lot of labor due to frequent turning to get the batches of dried fish first.

Dried fish has many different types. Therefore, the fish dryer needs to be qualified to be able to dry a variety of fish when needed. But at present, the dried fish is mainly dried by the sun drying method.
This is the typical way of drying fish.

Just prepare and add spices to the fish and then bring it to dry in the sun in a large area, the surface exposed to the sun is wide. This method is generally simple and inexpensive.
