Drying of Leaf Eating Grass

Leafy grass is a high protein, high nutrient forage and edible plant widely used in animal husbandry feed, health food and other fields. The traditional drying method is greatly affected by weather and is prone to nutrient loss and mold growth. To meet the demand for large-scale production, this case adopts a biomass pellet heat source drying equipment (specification: 12 meters x 2.3 meters x 6 layers), which can quickly complete drying within 4-5 hours through precise temperature control (70-80 ℃), with an hourly output of 200 kilograms, achieving efficient, energy-saving, and high-quality industrial production.

1. Customer requirements (The customer is a medium-sized forage processing enterprise, and the core requirements include:)

Efficient mass production: It is required to produce more than 200 kilograms per hour to meet the demand for continuous production.

Quality assurance: The finished product has a green color, a retention rate of protein and other nutrients of ≥ 85%, and a moisture content of ≤ 12%.

Energy saving and environmental protection: using biomass pellet fuel to reduce energy consumption costs and meet environmental protection requirements.

Stable operation: The equipment needs to adapt to the high moisture characteristics of leafy grass (fresh grass moisture content is about 75% -80%), and dry evenly without burning.

2. Analysis of process advantages

① Accurate temperature control: drying at 80 ℃ for 4 hours: rapid dehydration, suitable for orders in urgent need of delivery. Drying at 70 ℃ for 5 hours: A milder drying method with better nutrient retention, suitable for high-quality needs.

② Biomass heat source: 30% more energy-efficient than coal-fired, with lower carbon emissions, in line with the trend of green production.

③ Multi layer drying design: 6-layer design, uniform hot air circulation, avoiding local over drying or wet core.

④ High production capacity: stable output of 200 kilograms per hour, significantly improving production efficiency.

3. Application suggestions

Feed processing: After drying, it can be directly used as high protein forage or processed into grass powder or grass granules.

Food field: deep processing and extraction of proteins, chlorophyll, etc., used for health food or additives.

Storage and transportation: Sealed packaging after drying, moisture-proof and mildew proof, and long-term storage without deterioration.

This solution achieves a balance between efficiency, quality, and environmental protection through biomass heat source and layered drying technology, providing customers with a cost-effective solution for processing leafy grass. Similar equipment can be used for drying forage such as alfalfa and oak, and can be adapted by adjusting the temperature and time.
