Recommendations for Building a Rice Milling Warehouse, Rice Factory, or Coffee Roasting Warehouse
Constructing agricultural processing facilities like rice mills or coffee roasting warehouses requires careful consideration in terms of structure, ventilation, electrical systems, and food safety. Below are key factors to consider:

Things to Consider:
Proper Ventilation
Rice milling and coffee roasting machines generate heat and dust. Ensure good airflow to prevent overheating and dust accumulation.
Strong Foundation and Floor Design
Heavy machinery requires reinforced concrete flooring. Leave space for material handling and product logistics.
Electrical Safety System
Install proper grounding and standard-compliant electrical systems, especially in dusty environments to prevent fire hazards.
Pest and Insect Control
Since these are food-related facilities, implement measures to prevent pests, rodents, and insects.
Separate Storage Areas
It's recommended to separate raw material and finished product zones — such as paddy rice, milled rice, raw coffee, and roasted coffee — to ensure safety and product quality.
