1. Food preservation: Nigeria’s food market, especially seafood, meat and agricultural products, requires ice to prolong the freshness of food and prevent spoilage.
2. Fisheries: Fisheries is one of the important industries in Nigeria, and the caught seafood needs to be preserved with ice for transportation and storage.
3. Beverage industry: In hot climates, beverages are consumed in large quantities, and ice is used to make cold drinks, such as iced juice, soda, etc.
4. Hotels and catering: Restaurants and hotels need ice when providing customers with cold drinks and refrigerated food.
5. Medical use: Some medical facilities may need ice to preserve medicines or perform cold compress treatments.
6. Agriculture: Some agricultural activities may require ice to preserve agricultural product samples or perform special agricultural treatments.

However, the application of ice block machines in Nigeria may be limited by factors such as unstable power supply and insufficient maintenance and repair services.
