Ideal storage conditions for the dried product

In the processing of agricultural products, food and medicinal materials, drying raw materials is an important step to extend the shelf life, reduce storage costs and increase the commercial value of the product. However, for the dried product to truly achieve high efficiency in quality and shelf life, a key factor that many businesses still overlook is: ideal storage conditions for the dried product

So what are the ideal storage conditions? How can dried products always retain their color, flavor, nutrients and not get moldy during storage or transportation? The answer starts with the drying technology you use – and SUNSAY freeze dryer is a comprehensive optimal solution.

Maintaining ideal storage conditions for dried products is a key factor in extending shelf life and maintaining the quality of the finished product after processing.

Dried products – Value lies in preservation quality

When food, medicinal herbs or agricultural products are properly dried, the moisture content in the product is usually reduced to 5 – 12%. This is the ideal humidity range where microorganisms cannot grow, enzymes stop working and oxidation is inhibited.

However, if the post-drying storage process is not well controlled – just a few unfavorable factors such as high environmental humidity, fluctuating temperatures, or poorly sealed packaging – the product will quickly absorb moisture back, leading to mold, discoloration, loss of flavor and loss of use value.

Many businesses have invested in modern production lines but have left their dried products in unstable conditions, causing great economic losses. Therefore, it is necessary to clearly understand and fully prepare the ideal storage conditions for dried products, to ensure a closed value chain from processing to consumption.

What are the ideal storage conditions for dried products?

To maintain maximum quality for dried products, it is necessary to ensure 4 core factors in the preservation stage:

Dried products are very sensitive to environmental humidity. If the air in the warehouse is too humid (over 70%), the product is prone to reverse moisture absorption, leading to mold or softening. The ideal humidity is between 40 – 60%. You can use an industrial dehumidifier in the warehouse or store it in a sealed, vacuum-sealed package.
Temperature stability helps limit oxidation and prevent microbial growth. If stored at too high a temperature or in direct sunlight, the product may change color or lose quality. Ideally, the warehouse should be cool, dry, well-insulated, with storage temperature: 15 – 25°C.

Strong light, especially ultraviolet light, can destroy vitamins and change the color of dried products. Packaging should be UV-resistant or dark-colored, and products should be stored in a dark warehouse.
The packaging layer acts as a “shield” to protect the dried product from all environmental factors. The packaging should be resistant to water vapor, oxygen, bacteria and light. For high-end products, vacuum bags or bags with accompanying desiccant packets should be used.

SUNSAY freeze-drying technology – The foundation for optimal product preservation quality

If you want dried products to be preserved for a long time while still maintaining their original quality, you need to not only focus on the storage stage but also choose the drying technology right from the start. And this is when the SUNSAY Food heat pump dryer plays its outstanding role.

Dry at low temperature – preserve nutrients

SUNSAY freeze dryer operates at a temperature of 25 – 50°C, helping to preserve the maximum enzymes, vitamins and natural flavors in the product. This is a prerequisite to prevent the product from deteriorating during storage.

Effective moisture separation – reduces the risk of reverse osmosis

Freeze-drying technology uses dry air to gently and evenly separate moisture. After drying, the product reaches a stable humidity level (below 10%), helping to minimize the phenomenon of reverse osmosis if the packaging accidentally leaks.

Does not change product structure

For sensitive products such as bird’s nest, cordyceps, and precious medicinal herbs, preserving the fiber structure, color, and aroma is a vital requirement. SUNSAY freeze dryer meets this requirement, surpassing traditional heat drying technologies.

SUNSAY freeze-dried products – Meet long-term preservation standards

Freeze-dried fruits (mango, pineapple, jackfruit, blueberries, etc.): Freeze-drying helps preserve bright colors, natural sweetness, and no additives are needed. Proper packaging can preserve for up to 12 months without refrigeration.

Medicinal herbs – herbal teas (chrysanthemum, lingzhi, panax notoginseng…): Active ingredients are not destroyed by low-temperature drying. If vacuum packaging is used, the product will retain its value after 1 – 2 years.

Freeze-dried seafood (shrimp, squid, salmon, etc.): No fishy smell, keeps the meat structure intact, easy to preserve and packaged according to export standards.

High-end products such as bird’s nest and cordyceps: After drying, the fibers remain intact, clear white, not broken, and can be easily preserved with specialized vacuum bags.

Notes to optimize storage conditions after drying

Do not open the package frequently, unless using immediately – this can easily cause the product to absorb moisture back.
Do not place the product near heat sources, water or damp places such as toilets or kitchens.
Use high shelves to store goods in the warehouse, avoid storing directly on the ground – where humidity is often high.
Mark drying date, packing date, shipment for easy product life cycle control.
