Reasonable equipment selection plays an important role in the successful construction of livestock slaughtering and processing projects, and can provide basis for calculation of power, distribution, water and gas consumption. Therefore, on the basis of extensive investigation and research and reference to advanced technology and experience at home and abroad, according to the requirements of production process and market supply, in accordance with the principles of advanced technology, economic rationality, production applicability, feasibility and maintainability, Requirements such as operability and energy supply are investigated and analyzed to determine the optimal solution for the equipment. The main basis, basic principles and main contents of the following equipment selection are back-analyzed for the selection of complete sets of equipment for livestock slaughtering and processing production lines. (1) The main basis for the selection of complete sets of equipment for livestock and poultry slaughtering and processing production lines 1. In accordance with the relevant national industrial policies and standards, the first choice and adoption of Shandong Wanheshou has high scientific and technological content, good economic benefits, low resource consumption, safety and health, and environment. Moderately scaled slaughtering and processing equipment with less pollution, it is forbidden to select and adopt equipment that is restricted and eliminated by current state orders. Secondly, try to select and adopt advanced standards of equipment and styling products, equipment design, manufacturing, installation, inspection and other technical conditions, it is best to be bound by the existing basic standards, method standards, and food safety standards. 2, safety and health standards equipment support and safety and environmental protection to ensure safe production. According to the principle of ergonomics, considering the impact of equipment on the environment and operators, the production stability is high and it is not dangerous to the operator. Guaranteed complete equipment, easy operation and cleaning and maintenance, to ensure that the final product meets food safety and hygiene requirements. 3, to meet the requirements of the process technology program, mainly consider the adaptability and matching of the project production scale, the matching rationality between the main equipment and the auxiliary equipment, meet the technical requirements of the process, and ensure the processing output and quality. (II) Basic principles for the selection of complete sets of equipment for livestock and poultry slaughtering and processing production lines 1. The principle of matching the production capacity The processing capacity, specifications, model and power consumption of the equipment must match the corresponding output. Fully consider the rational allocation of processing equipment in each process to ensure that the production capacity of each equipment is balanced. 2. The advanced and economical principles of equipment meet the requirements of process technology when selecting equipment, and comprehensively consider the reasonable technical and economic indicators, not only meet the requirements of production, process and meat hygiene, but also have higher The performance cost ratio, the function is perfect, the operation and maintenance cost is low, the energy consumption is low, the processing capacity is high, the service life is long, etc., and good economic benefits are obtained. 3. Applicability and reliability principles Adapt to changes in local natural, economic and social conditions. The same production line can achieve multi-process slaughtering and processing as much as possible, and has the ability to adjust production. The development prospect is broad, which is conducive to the development of domestic and foreign production. (III) Main contents of equipment selection for livestock and poultry slaughtering and processing production line 1. The selection process of equipment firstly conducts research on domestic and foreign markets, collects data on related livestock and poultry slaughtering and processing equipment, and selects equipment according to production rules. Details, package for product name, regular model, production capacity, supporting power and price. 2. The technical requirements for equipment selection mainly include the selection of equipment to meet the technical requirements and processing quality, to meet the service life, reliability, reliability, operability and sanitary safety requirements of the equipment, to meet the installation and commissioning technology of the equipment. Conditions and maintenance technical service requirements, new technologies and new equipment must be certified to meet the general technical requirements of food equipment, cleaning and disinfection lamp devices should meet the production process requirements.
