What is the loss rate when drying 50kg of mango using SUNSAY freeze dryer?

During the process of processing and preserving agricultural products, one of the questions that many producers and businesses are particularly interested in is the loss rate during drying. Understanding the loss rate not only helps to accurately predict output, but also directly affects product cost, supply plan and business efficiency.

So when drying 50kg of fresh mango with SUNSAY freeze dryer, what is the loss rate? What are the factors that help SUNSAY achieve optimal drying efficiency? This article will help you explain in detail.

Loss rate when drying mangoes – The number that determines production efficiency

Drying is a method of removing water from food to extend its shelf life. However, during the drying process, the product weight will be significantly reduced, because most of the water is evaporated. That is the rate of loss during drying – an important factor that needs to be carefully calculated.

For mangoes – a fruit with a high moisture content of 75-85% – the drying process will significantly reduce the weight. On average, to produce 1kg of finished dried mango, about 10-12kg of fresh mango is needed, depending on the ripeness, mango variety, and drying method. Thus, when drying 50kg of fresh mangoes with a SUNSAY freeze dryer, the finished dried mango yield can reach 4.5-5.5kg, which means the loss rate is about 89-91% by weight.

Although this number may sound high, it is actually the standard loss for juicy tropical fruits like mangoes. More importantly: the SUNSAY freeze dryer does not cause any loss of nutrients – which is very likely to happen when using traditional heat drying technology.

What makes SUNSAY freeze dryer different?

At the same physical loss rate, what makes the dried product more valuable is the output quality. SUNSAY not only ensures standard dryness, but also retains color, aroma and nutritional value almost intact.

Freeze drying – Technology to preserve the value of mangoes

Unlike the convection drying method (which uses temperatures of 60–80°C), the SUNSAY food dryer operates at low temperatures of 25–50°C, preventing the mango from being over-ripe, from changing color, and from losing its natural flavor.

Thanks to heat pump technology and dry air circulation, the dehumidification process takes place slowly, helping to preserve enzymes, vitamins A, C and antioxidants that are easily decomposed at high temperatures. As a result, the dried mango is still supple, does not turn black, and does not require preservatives – a huge advantage if you are aiming for the export market or the high-end segment.

Optimize loss rate through smart control

SUNSAY freeze dryer integrates PID controller and PLC – HMI touch screen, allowing users to precisely set each parameter of temperature, humidity, drying time, helping to optimize each individual drying batch.

There is no phenomenon of burnt edges, hardening or darkening – common errors when using manual drying or conventional heat drying. Thanks to that, the physical loss rate, although unavoidable, is converted into dried products with high economic value.

Flexible operation, suitable for many scales

SUNSAY offers a wide range of freeze dryers with diverse capacities, from mini 12-tray models (30-40kg of raw materials/batch) to industrial 40-tray models (180-200kg/batch). This flexibility makes it easy for users to choose the right equipment for their specific needs: from households, small production facilities, to large-scale food processing factories for export.

With the requirement of drying 50kg of fresh mango, model SS-5712HP3D – 12 trays is the optimal choice. The machine is designed to operate a single batch, without the need to divide into 2-3 drying times as when using smaller capacity models.

Detailed analysis: Drying 50kg of mangoes – What is the efficiency?

Suppose you use 50kg of grade 1 Cat Chu mango, moderate ripeness, clean the skin and cut into thin slices (3-5mm), dry with SUNSAY cold dryer under standard conditions:

• Drying temperature: 40°C
• Drying time: 20–24 hours
• Moisture after drying: Below 15% (meets preservation standards)
• Average conversion ratio: 9:1 to 11:1

Once completed, you will get about 5 – 5.5kg of finished dried mango, depending on the mango variety and preparation method.

If overripe mangoes are used, the loss rate can be as high as 92%. But with the SUNSAY machine – the temperature and humidity control process is always stable – the output is always highly consistent.

Compared with heat drying: Same loss, different quality

Drying mangoes at high temperatures (gas drying, firewood drying, traditional electric drying) can help reduce time, but can easily cause discoloration, burn the edges of mango slices, reduce sensory value, and even cause the product to not meet export standards.

At the same time, many nutrients are easily evaporated or destroyed when drying at 60–80°C. Therefore, although the physical loss rate may be equivalent, the commercial value of the product after drying is much lower than that of SUNSAY freeze drying.

Long-term benefits of investing in SUNSAY freeze dryer

When analyzing investment efficiency, do not just stop at the loss figure, but also consider the whole:

• Save up to 70% electricity compared to heat drying thanks to heat pump technology
• No need for fuel (gas, firewood), environmentally friendly
• Dried products meet export standards
• Increase economic output value: 1kg of dried mango can be sold at 8-10 times the price of fresh ingredients.
• The machine is durable for over 20 years, made entirely of 304 POSCO stainless steel, rust-free, easy to clean.

Attrition Rate – Don’t Just Look at the Numbers

Drying 50kg of mango to get 5kg of finished product is not a loss – if the nutritional value, sensory value and output selling price increase many times.

With SUNSAY freeze dryer, you can not only control the loss rate during drying, but also master the quality, color, flavor and food safety – a prerequisite to compete in the modern market.

The loss rate when drying 50kg of mango using SUNSAY freeze dryer ranges from 89 – 91%, which means about 5 – 5.5kg of high-quality dried product is obtained. Although this rate is typical of a juicy fruit like mango, thanks to SUNSAY’s advanced freeze drying technology, the output product still achieves high uniformity, preserves nutrients and meets the standards of demanding markets.

If you are considering investing in mango drying technology, SUNSAY is a worthy choice to start or expand production. Not only is it equipment – ​​SUNSAY is also a solution to increase the value of Vietnamese agricultural products.
