Solution to reduce post-harvest loss thanks to freeze-drying technology
In Vietnam’s agriculture, reducing post-harvest losses is always a difficult problem. Every harvest season, millions of tons of agricultural products are lost due to adverse weather, suboptimal preservation processes or outdated processing methods. This reality not only causes economic losses but also directly affects the livelihoods of farmers, the reputation of businesses and the competitiveness of Vietnamese agricultural products in the international market.
Amidst these challenges, freeze-drying technology, especially SUNSAY freeze-dryers, is emerging as an effective solution to preserve the full value of agricultural products, prolong preservation time and minimize post-harvest losses.

The reality of post-harvest agricultural product loss
According to many reports from the agricultural sector, the rate of post-harvest loss of agricultural products in Vietnam ranges from 10 to 20%, even up to 30%. The cause comes from many factors. Firstly, the hot and humid tropical monsoon climate makes vegetables and fruits susceptible to mold and spoilage after only a few days.
Second, traditional preservation methods – such as sun-drying and wind-drying – although simple and inexpensive, are completely dependent on the weather and cannot control quality. Finally, deep processing infrastructure in many localities is lacking, causing products to be consumed mainly fresh, leading to oversupply and waste.
Loss is not just a matter of numbers. It is a waste of effort, investment costs and the nutritional value of agricultural products. For farmers, post-harvest loss means reduced income. For businesses, it is a major barrier when wanting to build a brand and participate in the global supply chain.
Freeze-drying technology – A step forward in preserving agricultural products
In this colorful picture, freeze-drying technology appears as a sustainable direction. Unlike traditional heat drying which uses high temperatures from 60 – 80°C, freeze-drying operates at 25 – 50°C, thereby not changing the color, flavor or destroying nutrients in agricultural products.
The operating principle of the SUNSAY food dryer is based on the heat pump mechanism and closed air circulation. The air is dried, gently heated and then blown through the raw material to absorb moisture. Then, the moist air is passed through the condenser to remove water, reused for the next cycle. This continuous circulation process helps to control stable temperature and humidity, creating an ideal environment for drying agricultural products while still preserving their natural value.
Importantly, thanks to this technology, agricultural products are no longer dependent on the weather, and there is no worry of mold or early spoilage. This is the decisive factor in effectively reducing post-harvest losses.
Economic and nutritional value are preserved
One of the biggest advantages of freeze drying is the ability to retain nutrients. Vitamins that are easily lost when exposed to high temperatures, such as vitamin C in mangoes, oranges or strawberries, are preserved by more than 90%. Antioxidants, enzymes and essential oils in medicinal herbs, mushrooms or herbs remain active. This not only helps the product retain its nutritional value but also improves its competitiveness when entering demanding markets.
In addition, freeze-dried products have bright colors, natural flavors and original textures. For example, freeze-dried bananas still retain their sweet taste, attractive golden mangoes, or shiitake mushrooms still have their characteristic aroma. This difference helps the product become a popular choice for consumers, thereby increasing its commercial value.
SUNSAY – Solution to accompany Vietnamese agricultural products
SUNSAY freeze dryer is designed to suit many production scales, from small households to export processing factories. With anti-rust 304 stainless steel frame, sealed drying chamber and automatic control system by PLC – HMI or PID, SUNSAY brings high durability, easy operation and energy saving.
SUNSAY’s air circulation mechanism not only helps products achieve consistent quality but also saves up to 50 – 70% energy compared to heat drying. With lower operating costs and higher value products, farmers and businesses can recover capital quickly, increasing sustainable profits.
In fact, many agricultural cooperatives and processing enterprises have been successful in applying SUNSAY freeze dryers. Thanks to this technology, they not only reduce post-harvest losses but also create dried products that meet export standards, expanding the international market.
Reduce wastage – Open up new opportunities
When post-harvest losses are reduced, the agricultural value chain is extended and enhanced. Farmers can sell their products at better prices, businesses have a more stable and quality source of raw materials, while consumers have access to safe and nutritious food.
For agriculture, this is also an important step in the transition from quantity production to quality. From only selling fresh agricultural products at low prices, Vietnam can export high-end processed products, increasing the value many times. This is the goal that SUNSAY freeze-drying technology is realizing day by day.
Towards sustainable development
In addition to economic benefits, freeze-drying technology also brings environmental value. The machine operates on electricity, does not use fuel, reduces greenhouse gas emissions and is environmentally friendly. Reducing agricultural waste also means reducing organic waste, contributing to building a green and sustainable agriculture.
In the context of climate change and increasing global demand for environmentally friendly products, freeze-drying technology is the right step for Vietnam to both develop its economy and meet international requirements.
Freeze-drying – The key to reducing loss and improving the quality of Vietnamese agricultural products
Reducing post-harvest loss is not only a desire, but also an urgent need for sustainable development of Vietnamese agriculture. And SUNSAY freeze-drying technology is proving that this is the optimal solution. By preserving the nutritional value, color, flavor and extending the preservation time, freeze-drying helps agricultural products not only avoid waste but also increase commercial value.
From farmers to processing enterprises, from domestic to international markets, freeze-drying technology is opening new doors for Vietnamese agricultural products to conquer global consumers. That is the way for agriculture to not only stop at production, but also step up to a higher level – sustainable and valuable production.
