Fresh pork blood (can be stored in fresh citric acid first) and wheat bran (rice bran) in a certain proportion, and then mixed with 1 gold and golden baby type 2 starter (which can be diluted with 5 times rice bran), after fermentation The dried feed has crude protein up to 45 and crude protein digestibility can reach over 90%. The method of fermentation of pig blood into feed is:
The pig's blood protein content is very high and should not be fermented separately. It should be mixed with energy feeds (such as cornmeal, wheat bran, etc.) and generally added in corn flour at a ratio of 30% to 40% (ie corn flour: blood meal = 70%: 30 %--60%: 40%). After adding well-mixed ingredients, add the golden bacon feed starter (first diluted with 5 times rice bran) according to one-thousandth to two-tenths of the total amount of feed. Mix well with the material. Depending on the situation, add water and mix well. The moisture content of the material is generally controlled at about 65%. The judgement method is: grab the fermented material tightly and grab a hand. The watermark can be seen through the fingers but not dripping. It is advisable to loosen the floor and release it. If the juice can be squeezed out and the floor does not spread out, the moisture content is too high, too dry and too wet, and it should be adjusted. After the material is adjusted, it is immediately loaded into pots, jars, pools, plastic bags, and other containers. It is sealed and fermented at natural temperatures for 2-3 days. It can be fed when it is fragrant, sweet, and alcoholic. When large-scale fermentation can be directly stacked in a clean concrete floor or fermentation tank, sealed plastic film can be sealed and fermented.
At present, to promote energy saving and emission reduction, the development of low-carbon economy has become the main theme of the development of the world economy, especially for China which is a relative shortage of resources per capita, serious ecological damage power development, in the huge pressure of energy and environment, promote energy-saving emission reduction, it is imperative to develop low carbon economy. In the Copenhagen world climate conference held in December 2009, the Chinese government commitment to the 2020 unit of GDP carbon emissions than in 2005 decreased by 40% ~ 45%. In the future, all walks of life will move towards low energy consumption, low pollution and low emission direction, the development of flexible packaging industry can not be contrarian. Soft packaging industry as one of the more serious energy consumption and pollution, in the face of increasingly prominent energy and environmental problems, should assume more social responsibility, to contribute to energy saving and emission reduction.
In China to use a large number of organic solvents, emissions of a large number of high concentration of organic waste gas is an important cause of environmental pollution caused by the soft packaging industry. At the same time, the evaporation of organic solvent in the process of use also caused the problem of indoor pollution and safety. With the increase of people's awareness of environmental protection and national environmental protection, organic emission problem of the soft packaging industry has aroused social attention, soft packaging enterprises also obviously feel the increasing pressure of environmental protection, high discharge mode used by now has been difficult to project eia. Moreover, the future of national legislation in the field of environmental protection will be more stringent, flexible packaging enterprises must be a pressing matter of the moment to take effective measures to reduce emissions and energy consumption of organic waste gas, in accordance with the national energy-saving emission reduction targets
