Does the convection drying technology of SUNSAY freeze dryer ensure even drying quality?

Convection drying technology is one of the important methods used in the drying process of food, medicinal herbs and other agricultural products. With the strong development of technology, SUNSAY has launched a line of freeze dryers applying advanced convection drying technology, helping to effectively improve the quality of dried products.

But does convection drying technology really ensure even drying quality? In this article, we will learn about the convection drying technology of SUNSAY freeze dryer and consider the factors that affect the even drying quality of the product.

What is the convection drying technology of the freeze dryer?

Convection drying is a process that uses circulating air to remove moisture from food or other products. In this system, cold or low temperature air is evenly distributed throughout the drying chamber, allowing moisture to evaporate from the surface of the product. This technology helps ensure that the air does not condense and maintains a dry drying environment, thereby ensuring drying quality.

One of the great advantages of the convection drying technology of the freeze dryer is that it helps save energy and maintain temperature stability during the drying process. This is very important for temperature-sensitive products such as medicinal herbs, fruits and other foods, ensuring that the product does not change in color, flavor or nutrients.

SUNSAY freeze dryer uses advanced convection drying technology

SUNSAY’s convection drying technology uses a multi-directional air circulation system, which helps distribute cold air evenly throughout the drying chamber. This ensures that every position in the drying chamber receives the necessary amount of air to remove moisture, helping the product dry evenly and not burn or retain unwanted moisture.

SUNSAY is equipped with a modern temperature sensor and control system, which helps to adjust the drying temperature accurately. This is very important in preserving product quality, especially for sensitive materials such as medicinal herbs and fruits. The food heat pump dryer  can maintain the ideal temperature and humidity throughout the drying process, thereby ensuring the quality of the final product.

One of the outstanding advantages of convection drying technology is its ability to save energy. With an effective air circulation mechanism, the machine does not need to consume too much energy to maintain stable temperature and humidity, helping to minimize operating costs while still achieving high efficiency.

SUNSAY’s advanced convection drying technology helps dried products retain most of the essential nutrients, such as vitamins and minerals. At the same time, the natural color and flavor of the product are also maintained, creating high-quality dried products that meet consumer needs.

Why does SUNSAY’s convection drying technology ensure even drying?

Multi-directional air distribution

SUNSAY’s convection drying system is designed with multi-directional airflow, meaning that cold air or drying air is circulated from multiple directions in the drying chamber. This ensures that the air comes into contact with the entire surface of the product, allowing the evaporation of water to occur evenly. As a result, no area in the drying chamber is underheated or lacks air circulation, allowing the product to dry evenly from all sides.

Powerful and stable air circulation system

SUNSAY freeze dryer is equipped with a powerful fan system, ensuring that the air flow is continuously and strongly circulated through the dried products. The stable air circulation system helps maintain a steady flow, avoiding the accumulation of moisture at a certain point or area, thereby drying the products more evenly.

Precise temperature and humidity control

One of the important factors that determine the uniformity of the drying process is the control of temperature and humidity. SUNSAY freeze dryers are equipped with extremely precise temperature sensors and controls. This ensures that the temperature in the drying chamber is always maintained at a level suitable for each type of product, thereby avoiding drying too quickly or too slowly, affecting the quality and uniformity of the product.

Design of airy drying tray

The drying trays of the SUNSAY machine are designed to optimize ventilation, allowing air to easily move through each product layer. The distance between the trays is reasonably calculated so that air can circulate without being obstructed, allowing all product layers to be exposed to the drying air, thereby ensuring uniform drying.

Automatically adjusts the drying process

SUNSAY’s convection drying technology allows the machine to automatically adjust the drying process based on information from temperature and humidity sensors. When changes in drying conditions are detected, the system will automatically readjust the temperature or air flow to maintain ideal drying conditions. This helps ensure that the product does not over-dry in one area and still maintains a balanced humidity level.

Ability to store and apply different drying programs

SUNSAY freeze dryers have the ability to store multiple drying programs suitable for each type of product, helping to optimize the drying process based on specific requirements. This helps to improve the uniformity of products when dried in the same batch, especially when there are many types of raw materials with different properties.

Ability to adjust fan speed and airflow

For each type of product, SUNSAY provides the option to adjust the fan speed and airflow direction in the drying chamber. The appropriate fan speed will help the air not be too strong (causing small products to fly away) or too weak (causing uneven drying), thereby optimizing the drying process for each type of food or medicinal material.

Thanks to technical factors such as multi-directional air system, precise temperature and humidity control, along with airy design and automatic adjustment, the convection drying technology of SUNSAY freeze dryer ensures even drying for all types of products. This not only helps to maintain product quality but also brings high efficiency in the production process.
