Inner Mongolia Bean Drying Project
1.Customer Needs
The Xing’an League region of Inner Mongolia boasts a vast acreage of bean cultivation, but traditional natural drying methods present numerous drawbacks:
Low processing efficiency: Traditional drying relies entirely on weather conditions. Drying a batch requires 2-3 days on clear days, while rainy weather can easily lead to mold and loss, limiting annual processing capacity.
Difficulty in ensuring quality: Open-air drying easily introduces impurities such as dust and mosquitoes, resulting in substandard hygiene, a dull color, and a lower product grade, significantly impacting sales prices.
Limited production capacity: Manual operations are labor-intensive, making large-scale production impossible and hindering further growth and development of the industry.
Local processors urgently need a mechanized drying solution that enables continuous production, is weather-independent, and is energy-efficient and efficient to meet the growing market demand for high-quality dried beans.

3. Bean Drying Process
Pre-treatment Steps
Raw Material Selection: Select fresh, pest-free, and mechanically undamaged beans.
Cleaning and Finishing: Thoroughly clean beans using a bubble washer to remove impurities.
Cutting: Beans can be cut into segments or shreds according to customer needs.
Drying Parameter Settings
Breading Thickness: 3-5 cm, evenly spread.
Temperature Control: Utilizes temperature control. Control
Initial Stage: 60-65°C (1-2 hours) to quickly remove surface moisture
Mid-Stage: 55-60°C (3-4 hours) for uniform dehydration
Late Stage: 50-55°C (2-3 hours) to ensure product quality
Drying Time: 6-8 hours per batch
Moisture Control: Reduce initial moisture content from 85%-90% to a final moisture content of 10%-12%
4.Process Features
Uniform Drying: The mesh-belt structure allows hot air to penetrate the material layer for uniform drying, avoiding overheating or under-drying.
Color Preservation: A systematic temperature curve effectively maintains the beans’ natural green color and excellent appearance.
Nutrient Retention Low-temperature, slow-drying technology maximizes the preservation of beans’ nutrients and flavor.
Hygiene and Safety: The enclosed drying environment eliminates secondary contamination and complies with food hygiene standards.
Post-harvest Processing: Cooling and Softening: After drying, beans are naturally cooled to room temperature to ensure even moisture distribution.
Sorting and Packaging: Beans are sorted by grade and sealed using food-grade packaging materials.
Storage: Store in a dry, cool, well-ventilated warehouse, away from direct sunlight.
Jinlu Machinery’s mesh belt dryers, with their superior performance and adaptability, provide reliable technical support for Inner Mongolia’s bean processing industry, promoting technological advancement and industrial upgrading in the local agricultural product processing industry.
