Steam Explosion Technology
Gas explosion refers to the use of high temperature and high pressure steam explosion technology, the agricultural and forestry waste, wild plants and other unconventional coarse feed raw materials processed into filamentous, coke flavor, good palatability of mature coarse feed.
The core technical link is the wall-breaking "nitrogen addition" process of roughage, which is mainly used to blast the raw materials through steam, cook the fiber raw materials with high temperature steam under high pressure, and realize the component separation and structural change of the raw materials through the instantaneous pressure relief process. In the process of steam explosion, high-pressure hot steam enters the fiber raw material and penetrates into the internal voids of the fiber. Due to the combined effect of water vapor and heat, the acid-like degradation and thermal degradation of the fiber raw material are produced, and the low molecular material dissolves out, and the degree of polymerization of the fiber decreases. When the high-pressure steam is released, the hot steam molecules that have penetrated into the fiber are instantly released from the relatively closed pores at high speed in the form of air flow. The high-speed and instantaneous flow of hot steam inside and around the fiber causes mechanical fracture to some extent, thus breaking the intertwining of lignin, cellulose and hemicellulose in the straw raw material, thus realizing the feed utilization of straw and turning waste into treasure.
The crude fiber in roughage is mainly composed of cellulose, hemicellulose and lignin. Among them, cellulose and hemicellulose can be directly used by ruminants such as cattle and sheep into energy substances, lignin can not be used by ruminants. In the physical structure of roughage, cellulose and hemicellulose are wrapped in lignin and cannot be digested and absorbed by ruminants, usually less than 20%. Through the instantaneous pressure release process of steam explosion technology, the dense fiber structure inside the molecule can be broken, the nutrients wrapped in the lignin can be released, and the utilization efficiency of feed nutrients can be improved.
Interpretation of Characteristics of Gas Explosion Fermented Feed
01
Straw shrub broken “plus nitrogen” feed in the production process by high-temperature steam poisoning, no risk of epidemics, no pesticides, fertilizers, herbicides residues.
02
Straw and shrub broken “nitrogen” feed is a kind of roughage, but the nutritional value is close to that of concentrate feed. The nutritional value of each kilogram of Strawberry Bush “nitrogenated” feed is equivalent to 0.6-0.7 kg of maize. The net milk yield of maize is 1.83 Mcal/kg, while the net milk yield of stover-bush “nitrogenated” feeds produced from maize or rice straw is as high as 1.72 Mcal/kg and 1.78 Mcal/kg, compared to alfalfa's net milk yield of 1.24 Mcal/kg.
03
Straw shrub wall-breaking “plus nitrogen” feed for high-yield dairy farming, can solve the problem of imbalance of the ratio of concentrate to roughage in the diet, to ensure the health of dairy cows, and to improve the yields of dairy cows. It can be used in low and medium yielding dairy cows to reduce the amount of concentrate feed, reduce the cost of breeding and increase the milk fat rate while guaranteeing the yield of cows.
04
Straw and shrub broken “nitrogen” feed is a kind of cooked and puffed feed, puffing effect is much better than extrusion puffing, cattle and sheep digestion and absorption rate of up to 70%. With straw and shrub broken “nitrogen” feed as the main feed for raising cows in the feces, almost can not be seen in the feces of conventional dairy cows in the plant fiber.
05
Straw and shrub broken “plus nitrogen” feed is produced on an industrial scale, with stable and reliable quality, which can guarantee year-round supply. Breeding enterprises do not need to hoard, easy to buy, and occupy less capital. On the other hand, most of the common forage grasses need to be dried manually, which is seasonal and cannot guarantee stable supply.
06
Straw and shrub broken “nitrogen” feed is a real green forage, which can be used for the development of ecological farming, the production of better quality beef and sheep meat, and generate higher economic benefits;. The non-fibrous carbohydrate content of straw and shrub broken “nitrogen added” feed is up to 30-40%, which is suitable for the production of nutritionally balanced full-value fermented feed, which is the direction of development of ruminant feed products, and can greatly reduce the cost of farming and improve the efficiency of farming.
