New equipment that has not been subjected to production practices or has technical problems left behind cannot be used blindly; high production stability and no danger to personnel Hazardous substances exceeding the national standards shall not be discharged into the workplace and the atmosphere, and noise, vibration, radiation and other pollutions exceeding the national standards shall not be produced. The service life is long, the equipment has no working time, and the equipment can be repaired if there is a sanitary failure. After using a certain limit, it can not be repaired. Equipment that is not clearly defined is usually considered for a design life of 20 years, and the service life is specified in detail.
Technical and economical rationality: equipment selection is based on domestic products as much as possible. Because the price of domestically produced equipment is cheap, equipment purchase should be considered domestically. If domestic equipment cannot meet the process requirements, production requirements, quality requirements, etc., then consider purchasing foreign equipment; equipment configuration It should be balanced and reasonable, considering the comprehensive economics of the entire production line configuration, requiring equipment configuration and connection to be compact, balanced, coordinated, and improving labor productivity; improving technical and economic value, conducting repeated technical and economic program comparisons, and analyzing the technical and economic benefits of each program. Choose equipment options with small investment, low cost, high profit and reasonable economics.
Equipment selection The main content of the equipment selection program technical parts: the degree of assurance of the equipment program on food processing, mainly including the equipment to the scale of construction, product program satisfaction, the degree of food processing quality and production process requirements; the service life of the equipment , reliability, material consumption index, operation requirements, guarantee degree of spare parts to the project; technical conditions for equipment installation and commissioning, maintenance technical service, and required equipment investment to meet the project; equipment supporting requirements, new Technology and new equipment must pass the technical appraisal and industrial test to prove that it is a mature technology. The equipment combination plan should realize the equipment matching of different production links, the matching of production equipment and auxiliary equipment, the matching of domestic equipment and imported equipment, the original equipment and the newly added equipment. Matching. The production capacity of the equipment shall be set according to the scale of production and appropriate, and shall be compatible with the output of the product; the material requirements of the equipment plan shall be used for food processing areas and equipment and utensils that may come into contact with food, and no toxins or no The manufacture of materials that are odorous or odorous, non-absorbent, corrosion-resistant and can withstand repeated cleaning and disinfection. The materials of the equipment and piping that are in direct contact with the material should not chemically react with the material. The direct contact surface with the material shall be smooth, square, easy to clean and corrosion resistant; the manufacturing requirements of the equipment program shall be such that the structure of the food processing equipment shall prevent product contamination, the contact surface of the product and the inner packaging material are easy to clean, disinfect and repair; food contact The surface should be smooth, free from dents or cracks, so that the growth of microorganisms can be reduced to a low limit, pay attention to the safety protection of equipment configuration; when equipment safety and health measures conflict with economic benefits, safety and health requirements should be given priority.
