Okara, also known as soybean pulp, is a byproduct of tofu and soy milk production. Although rich in fiber and protein, fresh okara has a high moisture content (about 80%), making it highly perishable. To extend its shelf life and enhance its usability in animal feed, food products, fertilizers, and even cat litter, industrial okara dryers play a crucial role.
Industrial okara dryers utilize advanced drying technologies to reduce moisture content efficiently. These dryers typically use hot air circulation, rotary drum drying, or flash drying systems. The drying process generally includes pre-dewatering, controlled heating, and moisture removal through evaporation.
Pre-dewatering: Before drying, mechanical dewatering removes excess moisture, reducing energy consumption.
Heating and Drying: Heating and Drying: The okara is fed into a rotary drum or flash dryer where hot air circulates through the drum to extract moisture. The temperature is carefully controlled to prevent nutrient loss.
Final Moisture Adjustment: The drying process continues until okara reaches a stable moisture level (usually below 12%), making it easier to store and transport.
Once dried, okara can be used in various industries, including:
Animal Feed: A nutritious and cost-effective supplement for livestock and poultry feed.
Food Industry: Added to baked goods, snacks, and plant-based protein products.
Fertilizer Production: Used as an organic soil enhancer due to its rich nutrient content.
Cat Litter: Processed into biodegradable and eco-friendly cat litter with excellent absorbency and odor control.
