At present, the productivity of feed processing machinery commonly used in China is not very high. For example, the maximum output of domestic extruders is 3 to 5 tons per hour, which is a certain gap compared with foreign countries. In the development of feed processing machinery, advanced countries in the United States and Europe are undoubtedly in the forefront, and their stand-alone equipment automation and complete sets of equipment are automatically controlled to a higher degree. In order to reduce the impact of this gap, China's feed machinery industry should develop in the direction of scale and intensification, and reduce production costs and management costs through the expansion of sales volume, thereby improving efficiency.
The rapid development of China's feed industry has greatly promoted the development and progress of feed machinery. In recent years, the development of China's feed machinery industry has been changing with each passing day, and it has also made breakthroughs in technology. Feed processing enterprises have further improved the requirements for mechanization and automation procedures of feed processing equipment. This paper mainly discusses the development status and trends of China's feed machinery industry, in order to find the future development direction of this industry.
China's feed processing machinery intelligent development of the road is still very long
First, the status quo of feed machinery industry
At present, feed processing enterprises are developing towards group and large-scale development, and large-scale feed processing equipment will be developed, mechanized, and the degree of automation will be further improved. Feed machinery manufacturing enterprises are also developing towards grouping and scale. For example, Jiangsu Zhengchang Group and Jiangsu Muyang Group were established in 1995 and 1996 respectively. They are large-scale feed machinery production groups that combine feed machinery production, grain and oil complete projects, dust removal projects, steel silo engineering and electrical engineering, agriculture, animal husbandry and feed, and biotechnology. Some state-owned, private, joint venture and wholly-owned feed machinery manufacturers integrate machine, electricity, technology and civil engineering into one, undertake turnkey projects and realize one-stop service.
According to China's national conditions, the breeding industry will show a combination of large-scale breeding and scattered breeding. The scale of feed processing will also be large, and small and medium-sized coexistence. Therefore, large, medium and small feed processing machinery will have a certain market. For existing feed machinery, it is necessary to further improve product quality, increase variety and scale, and meet the needs of different users. At the same time, appropriate introduction of the necessary foreign advanced technology and equipment, digestion and absorption, and development of new products. Strengthen exchanges with relevant industries, transplant relevant equipment from other industries, and improve applications to meet the evolving needs of the feed industry. For the new feed processing technology and equipment, feed resource development and pet feed, aquatic animal feed and economic animal feed processing equipment should be properly invested in research and development, and technical reserves to meet future needs.
Second, the lack of feed machinery development
Some aspects of China's feed technology and equipment have reached the advanced level in foreign countries. However, there are some shortcomings in the development of feed machinery in :
1 There is a shortage of some urgently needed feed machinery, which is difficult to meet market demand. In the absence of suitable and stable use, suitable for farmers, simple operation, low power consumption, single or supporting simple and flexible processing equipment; high-efficiency, fully automated processing equipment required by large-scale feed processing plants; suitable for scale farming Large, medium and small-scale cooked feed equipment used by the field for self-use or professional feed mills. Solve the problem of various heat-sensitive trace elements and microbial loss in the hot processing of feed, after the quenching and tempering, excessive addition before extrusion, the technical problems of adding inaccuracy and the post-spraying facilities of liquid and recycled elements; enzyme preparation and microorganism Fermented feed production equipment; aquaculture feed puffing and granulating facilities with stable performance and moderate price.
2 The overall technical level of feed machinery is low. The first is poor reliability and short life. The second is that China's feed machinery has many small and medium-sized manufacturers, with low serialization, generalization, and low standardization. There are fewer professional factories and chaotic mechanical models. The developed countries have better after-sales service, and the standardization and standardization of parts are high. The third is the poor quality of the mechanical appearance and surface protection. When many products arrive at the destination, the paint peels off and is rusty. This is a major problem with domestic equipment. The fourth is the lack of high-tech applications, the low degree of feedback control of mechanical operation and automatic monitoring of work quality, and the ease of use and comfort.
3 The ability to innovate is weak, and the development and development of new products are slow. Throughout the domestic feed machinery, due to the low profits and funds of various enterprises and research units, the development, development and innovation of new technologies and new equipment are slow and cannot meet the needs of market development.
4 Insufficient testing and inspection, production units are messy, and many manufacturers who do not have production conditions substitute materials, lower prices and lower quality. The phenomenon of unqualified feed products is common, especially the feed conversion rate produced by small feed producers is low, waste is serious, and the phenomenon of abuse of additives is serious, resulting in unsafe factors.
5 There are hidden dangers in feed safety work. Feed safety is not only related to the vital interests of farmers, but also related to the health of the people.
Third, the development trend of feed processing machinery
1 Mechanical equipment tends to develop in a large-scale direction. At present, due to the development of feed processing enterprises in the direction of grouping and large-scale, large-scale feed processing equipment will be developed, and the degree of mechanization and self-motivation will be further improved. Feed machinery manufacturing enterprises are also developing towards grouping and scale. In addition to the construction of new production workshops, it is also a feasible solution to transform the old feed production line and increase the output per shift.
2 heat treatment processing technology is the development trend of feed processing. From the current development of the feed industry, the maturation processing technology represented by puffing/expansion is gradually becoming a new development trend. Puffing/expansion can improve the hygienic safety of the product, passivate the anti-nutritional factors in the feed, enhance the palatability of the feed, increase the feed capacity of the feed, and improve the feed utilization rate. Abroad, technology has begun to spread in the feed processing industry, bringing revolutionary changes in the fields of pet feed, aquatic feed, early weaned pig feed, ruminant supplement protein production and feed resource development. The application of puffing/expansion technology in China's feed industry is still in its infancy, but with the in-depth study of related processes and equipment, it has become more and more important to people, and has become the most promising feed processing technology.
3 liquid spraying technology is an important measure to improve the quality of feed. Due to the increasing use of thermal processing equipment in feed mill equipment, such as extruders, expanders, granulators or other types of acclimatized equipment and high temperature short-term processing equipment, the feed is in the process of granulation, extrusion and expansion. It is strongly affected by temperature, pressure and moisture, and destroys most of the effects of heat-sensitive nutrients such as vitamins, enzyme preparations and other additives. The post-spraying technology is a new technology to solve this problem, adding heat-sensitive nutrients (such as vitamins, amino acids, enzymes, microorganisms and drugs), and the equipment is behind the thermal processing. To ensure the non-distortion of the feed formula, reduce the heat-sensitive trace element pre-mixing and excessive addition, the inaccuracy of heat loss during the heat-regulating pressure granulation process, reduce the feed cost increase and the addition of added ingredients after the excessive addition of the mixture before mixing The uncertainty of quantity makes feed production meet the higher requirements of safety and hygiene. Liquid post-spraying technology is a new technology that has been recognized in recent years to solve the loss of heat-sensitive micro-ecological preparations and nutrient elements such as trace elements and enzyme preparations. Due to its incomparable superiority, it will be rapidly developed.
