Food and agricultural product preservation is increasingly high, the use of dryers is more popular than ever. However, the question that many consumers and businesses ask is whether the dryer consumes electricity? This is an important issue, especially when electricity costs are increasing. Investing in a dryer must not only meet the needs of product quality but also ensure savings in operating costs, especially electricity.
SUNSAY freeze dryer is the ideal solution for this problem. With advanced heat pump technology, SUNSAY freeze dryer not only helps save up to 70% of electricity compared to traditional heat dryers, but also ensures the quality of products after drying. So, is SUNSAY dryer the optimal solution to save electricity and improve production efficiency? Let’s explore!

What is SUNSAY freeze dryer?
SUNSAY freeze dryer is a line of machines that use heat pump technology (Heat Pump Drying) to remove moisture from products without using high temperatures. Unlike traditional heat dryers, freeze dryers do not heat the air to dry food. Instead, the heat pump system helps remove moisture through an effective dehumidification process, while preserving the color, flavor and nutritional value of the product.
SUNSAY’s freeze-drying technology is highly appreciated for its ability to save energy and outstanding drying efficiency. With this operating principle, SUNSAY freeze-dryers help products dry quickly and evenly without losing nutrients, especially important vitamins and enzymes in food.
Is the dryer energy-consuming? Discover superior energy-saving technology from SUNSAY
SUNSAY dryers are designed to save energy effectively. SUNSAY’s modern dryer lines, especially the Heat Pump Dryer, use heat pump technology, helping to reduce energy consumption by up to 50-70% compared to traditional heat dryers.
This heat pump technology works by using a refrigerant compressor to remove moisture from food without raising the temperature too high, saving energy while maintaining optimal drying efficiency. At the same time, the automatic control system (PID or PLC) helps optimize electricity usage, avoiding energy waste.
If you are looking for an energy saving solution, SUNSAY dryer is definitely the right choice.

Operating principle of SUNSAY freeze dryer
SUNSAY Food dryer operates on the principle of an effective cooling and dehumidification system. The process begins when cold air from the outside environment is drawn into the machine through the compressor. The compressor will increase the pressure and temperature of the air, then the air is heated and sent to the drying chamber. Here, the hot air will blow through the drying trays containing food, helping to slowly dehumidify without affecting the quality of the product.
Once the air has been dehumidified from the food, it will be sucked back into the system to cool and continue the circulation process. Thanks to this closed circulation system, the SUNSAY freeze dryer can save maximum energy and ensure the drying process is continuous without changing the air source.
Benefits of using SUNSAY freeze dryer
Retains color, flavor and nutrition
SUNSAY freeze dryer helps to preserve the natural color, flavor and nutrients in food. By not using high temperature, freeze dryer helps to preserve vitamins, enzymes and biological active substances in fruits, medicinal herbs, seafood and many other foods. This is especially important for products requiring high quality such as dried fruits, cordyceps, ginseng, or medicinal products.
Freeze-dried products from SUNSAY machines do not change in color, do not lose their natural flavor, and especially retain important nutrients such as vitamin C and antioxidants, helping the product have higher nutritional value.

Save energy and operating costs
With heat pump technology, SUNSAY cold dryers save up to 70% of electricity compared to traditional heat dryers. Reusing energy helps reduce electricity costs for businesses and households. Automatic control systems with advanced technologies such as PID (Proportional Integral Derivative) and PLC (Programmable Logic Controller) help optimize electricity usage and maintain stable drying performance.
This is of great significance to food production facilities, especially in the context of increasing electricity prices. Using SUNSAY freeze dryers not only helps reduce operating costs but also contributes to environmental protection by using less electricity.
Dry evenly and quickly
With intelligent control system and convection drying technology, SUNSAY freeze dryer helps products to be dried evenly without having to turn the trays. This ensures that every product achieves perfect dryness, avoiding the burning or uneven moisture like traditional drying methods.
The drying process is fast, saving time and improving production efficiency. In particular, SUNSAY freeze dryers can operate continuously without reducing performance, ensuring high productivity for large production facilities.
High durability and easy to clean
SUNSAY freeze dryer is made from high-grade 304 stainless steel, ensuring long-term durability and rust resistance, ensuring food hygiene and safety. 304 stainless steel material not only helps the machine operate stably but also makes it easy to clean after each use. The drying trays are designed to be easy to disassemble, making cleaning the machine simple and convenient.
In particular, SUNSAY freeze dryer can be used continuously for a long time without any breakdown, helping users feel secure about product quality throughout the operation process.
