[Video] Ninh Binh Rattan & Bamboo Export Drying Process: Save 65% Energy with Daxwell & DeAir

The Solution to the "3 NOs" Problem of Craft Villages

Handicraft workshops (Rattan, Bamboo, Seagrass, Water Hyacinth) in Ninh Binh and the North often face the "3 NOs" situation during the humid season: NOT drying evenly - NOT retaining color - NOT meeting schedule. Relying on sun drying or using old electric resistance/coal kilns causes a very high rate of cracking, breakage, and mold, seriously affecting export orders.

This article will take you on a virtual tour of a production workshop in Ninh Binh that has completely transformed thanks to applying a closed drying and curing process with Daxwell & DeAir technology.

1. [Real Video] Efficiency of Daxwell Heat-Pump Dryer

We invite you to watch the video recording the direct operation of the Daxwell Heat-pump dryer at the customer's factory:

The "speaking numbers" from the project:

Energy Saving: Electricity costs reduced by up to 65% compared to previous resistance kilns.
Superior Quality: Cracking and warping rate reduced to below 1%, easily passing strict export inspection standards.
Processing Speed: Drying time shortened to only 8 - 12 hours/batch.

2. Heat Pump Cold Drying Technology: Why No Cracking?

Unlike direct heating drying (which causes the surface to dry quickly while the inside remains wet, causing cracks), Daxwell Heat-pump dryers operate on the principle of moisture separation at a low temperature range (25°C - 80°C).

COMPARISON OF RATTAN & BAMBOO DRYING TECHNOLOGY

Criteria	Old Kiln (Resistance/Coal)	Daxwell Dryer (Heat Pump)
Temperature	High, hard to control (easy burning/cracking).	Stable, wide range 25-80°C.
Water Removal Mechanism	Forced evaporation (Damages structure).	Slow moisture withdrawal (Retains flexibility).
Color	Easily dull, smoke-stained.	Retains natural bright color.

According to forest product processing research documents from FAO, bamboo and rattan need to be dried under strictly controlled regimes to avoid "case hardening" - the main cause of cracking during processing.

Daxwell Heat-pump dryer installed in the drying room in Ninh Binh — Daxwell drying system with smart HMI screen helps automate the drying process.

3. "Dual" Curing Warehouse: The Secret to Absolute Anti-Rehumidification

After drying, if left in a humid environment, rattan and bamboo will re-absorb moisture within a few hours (Re-humidification). To solve this thoroughly, the Ninh Binh customer invested in an additional Curing Warehouse using the DeAir.RE-H Heat-pump Dryer/Dehumidifier.

DeAir.RE-H heat-resistant dryer/dehumidifier operating in rattan and bamboo curing warehouse — DeAir.RE-H maintains warm temperature and low humidity, preventing mold growth.

Role of DeAir.RE-H:

Maintains warehouse temperature around 45°C - 50°C (Temperature level where mold cannot grow).
Continues to separate residual moisture deep inside the product core.
Ensures goods are always in 100% "bone dry" state before container loading for export.

4. FAQ on Rattan & Bamboo Drying Process

How does the Daxwell Heat-pump dryer save electricity?

Unlike resistance dryers that consume a lot of energy to heat the heating element, the Daxwell Heat-pump dryer operates on the principle of a heat pump (recovering heat energy from the condensation process). As a result, the machine saves up to 65% of operating electricity costs.

Can this machine dry products other than rattan and bamboo?

Yes. With a wide operating temperature range from 25°C to 80°C, the multi-function Daxwell dryer can dry agricultural products, herbs, wood, seagrass, water hyacinth... while ensuring quality.

Is operating the dryer complicated? How many people are needed to watch it?

The operation process is fully automated. The machine is equipped with a smart HMI screen, allowing pre-setting of drying stages. You do not need staff on duty 24/24, significantly reducing labor costs.
