The raw materials for the processing of high-quality dry grass are mainly high-yield, high-quality soybean pastures and mixed soybean and herbal grass. It is not appropriate to process dry weeds with weeds, higher woody levels (10 per cent or more) and large, rough and hard pastures with a gross fibre content above 33 per cent, and juicy and green grass with a moisture content above 85 per cent. The following are the main categories of good raw materials for the processing of herbide:
The vermin. It suits the north. Selenium powder is one of the most productive and most widely used in the world。
Sandbath. It is one of the high-yielding pastures in the wind and sandlands, which are suitable for sowing on sand, so that we can use them to make dry grass。
Red bean grass. Suitable for planting in semi-arid areas, dry grass is easier to make, and is a good raw material for processing straw powder, which is suitable for use because of its thick base。
Wild pasture. Wild pastures that grow on natural grasses can also be made of dried grass, such as weeds, old mangley, beryllium, etc., provided that they are of good quality, nutritional value and are not mixed with toxic grass。
Processes and methods used for the processing of straw powder are generally harvesting, cutting short, drying, shredding, packaging and storage。
Harvest. The quality of dry straw powder is highly correlated with the period during which the raw materials are harvested, and it is important that it be acquired at the highest nutritional value. The first harvest of the general legume grass should be at the beginning of the pregnancy bud, and subsequent harvests should be at the end of the pregnancy bud; the grasses should be at the end of the precipice and not later than the spiking period。
Cut short. Shortage is the simple processing of harvested grass in the production of herbs, which facilitates full shredding of the reprocess; in some cases, the process is not short-cut, but is followed by direct shredding when the harvested grass is naturally dried。
Dry. It is best to use artificial drying or mixed dehydration drying in herbal powder production. The method of mixed dehydration drying is the drying of fresh pastures from harvesting for a period of time in the field, until the amount of water in the pasture is reduced to a certain level, which is transported directly to the plant for subsequent drying, and the artificial drying is the placement of short pastures in the dryer and rapid dehydration of pastures through high-temperature air。
Crush. Crushing is the last and most important process in the grass-powder process, which has a significant impact on the quality of the grasspowder and therefore requires higher technology. The herds are crushed, increasing the area of the feed exposure surface and facilitating the digestion and absorption of animals。
