Heat balance of the unit for grass meal production

Abstract

Grass meal is as good as the grain components by its nutritional value, but excels them in nutritional value of protein and vitamins. One kilogram of the grass meal contains 0.7–0.8 feed units, 16–18% of the digestible protein, and up to 30 mg of carotene. During the high-temperature drying of the green material of the perennial grasses, these indices can be increased 1.5–2 times. The heat balance of the unit AVM-0.4 is represented permitting to analyze the possibility to reduce the heat carrier consumption of some processes. The line of the high-temperature drying of the grass in the pseudo-fluidized bed is offered where the optimal conditions of heat transfer and yield of the finished product and its separation into fine and coarse fractions are provided.
