Does the convection drying process in SUNSAY freeze dryer ensure quality?
The convection drying process in the freeze dryer is one of the most effective and popular drying methods, widely applied in the preservation and processing of food and agricultural products. SUNSAY freeze dryer not only utilizes the principle of convection heat transfer but also combines with advanced freeze drying technology, helping to maintain product quality at an optimal level.
In SUNSAY’s convection drying system, air is dried and cooled before being blown over the surface of the material. This helps to increase the ability to remove moisture from the product without high heating, minimizing the risk of losing nutrients, natural flavors and colors.

Concept of convection drying
Convection drying is a drying method that uses air to remove moisture from a product. In this process, hot air is blown over the material to be dried, helping to evaporate water and reduce moisture in the product. This process is continuous, helping to ensure that the product is dried evenly and uniformly.
Working principle
SUNSAY freeze dryer works on the principle of convection, in which air is heated and circulated around the product. As a result, the moisture in the product is effectively extracted. This process not only reduces moisture but also retains the flavor, color and nutritional value of the product.
Outstanding advantages of convection drying process in SUNSAY freeze dryer
- SUNSAY freeze dryers operate at low temperatures (usually below 50°C), helping to preserve the maximum flavor, color and nutritional value of food. This is especially suitable for products sensitive to high temperatures such as fruits, herbs, and seafood.
- Compared with traditional drying methods, cold-convection drying technology consumes less energy because it does not require high heating. This not only saves operating costs but is also environmentally friendly.
- The intelligent control system in the SUNSAY machine ensures even air circulation throughout the drying trays, helping the product dry evenly and reach the desired humidity.
Convection drying process in SUNSAY freeze dryer
Step 1: Prepare ingredients
Raw materials are carefully pre-processed, cleaned and classified before drying. Some foods need to be blanched or lightly chemically treated to preserve color and prevent oxidation.
Step 2: Put the ingredients into the dryer
Raw materials are placed on stainless steel drying trays, with suitable thickness (usually 5-8 kg/m²). SUNSAY dryers use high-quality 304 stainless steel, ensuring food safety and equipment durability.
Step 3: Convection drying process
Air dehumidification: Humid air is treated through a drying and cooling system, maintaining low humidity in the drying chamber.
Product drying: Cold dry air blows across the material surface, absorbing water vapor without affecting the structure and chemical composition of the product.
Automatic adjustment: Temperature, humidity and air flow are automatically controlled to optimize drying efficiency.
Step 4: Finish and preserve
When the required humidity is reached (usually 5-15% depending on the product), the raw materials are cooled and packaged in sealed containers for long-term preservation.
Product quality after drying by convection technology
Retains flavor and color
The natural flavor and color of the product are often the first factors to be damaged during the drying process. However, SUNSAY freeze dryer with superior convection drying technology has completely overcome this problem.
The air is heated at a low temperature and maintained at a stable level, helping to protect sensitive flavor compounds and retain the natural color of the product without changing them. The dried product is always fresh and delicious, attracting consumers at first sight.
Preserve nutritional value
A highlight of SUNSAY convection drying technology is the ability to almost completely preserve important nutritional components. Thanks to the application of precise temperature control techniques, essential vitamins and minerals are not destroyed by high temperatures.
As a result, the product not only retains its natural nutritional value but also meets the strict standards of export markets, enhancing the value of Vietnamese agricultural products in the international market.
Food safety
The drying process of SUNSAY food heat pump dryer not only produces high quality products but also meets all food safety requirements. By strictly controlling temperature and time, the drying process eliminates the risk of bacteria and mold growth, ensuring that the product is stored in safe conditions. This not only prolongs the storage time but also enhances consumer confidence in the processed product.
SUNSAY’s convection drying technology is not only a drying solution but also a bridge to help increase the value of agricultural products and food, thereby creating a strong mark in the modern processing industry.
