Food machinery product quality design, is in the food machinery design of the product quality requirements, determine the product quality level (or quality level), choose the main performance parameters, the provisions of a variety of performance parameters of the reasonable error range, the development of tolerance standards and other technical conditions, etc.. Whether it is the development of new products, or the improvement of the old products, it must be through the process of product quality design. Food machinery design process of quality management, the key is to do a good job in product quality design. In concept, the quality of food machinery product design is a kind of user driven and quality driven integrated design idea. It is concerned with the quality of the product, it is emphasized that the quality is effectively integrated into the product design, rather than free from the design.
1, product quality characteristics of food machinery product quality characteristics, directly affect the product's applicability or applicable degree.
A more complex food machinery can be composed of many parts, and each part contains many quality characteristics, the quality of the amount of the value of the product quality if beyond the specified limits, will have different effects on product quality. Some quality characteristics, although not meet the requirements of the design, only slightly affect the product function; and other quality characteristics is otherwise, if not meet the requirements, it is likely to cause personal safety and food safety hazards, or to the extent of adverse effects on product function. If these quality characteristics are mastered in the design, the appropriate design method, control method and detection method can be used to solve the risk. Therefore, in the process of production and manufacturing of food machinery, there is a kind of information on the quality of safety, health, function and so on. In addition, through the food machinery product quality characteristics of important degree classification, and pass to the process, manufacturing, inspection and purchasing department, so that these departments in the formulation process plan, manufacturing quality control plan, process quality control plan, preparation of test plan and procurement control plan, the key to take preventive measures, this is the product quality of a preventive control means or method. From the development of food machinery manufacturing industry, the quality of its products has experienced from the product oriented, manufacturing oriented, sales oriented to today's market oriented stage. In order to meet the requirements of the product, the quality of the product is expected to meet the requirements of the functional requirements; in addition to meet specifications, product specifications, product specifications, product specifications, quality assurance, quality assurance, product specifications, quality assurance, product quality: the quality of the product is defined as "a set of quality products, such as" three packs ". The intrinsic properties of the product are the components of the product forming process. Therefore, today said the food machinery product quality, refers to the product function, technical performance, safety and health, reliability, adaptability, economy, etc., to meet the needs of users and other beneficiaries. Can be seen, with the development of industrial technology and productivity improvement, the definition of product quality is constantly expanding.
2, product quality design tasks and steps
2.1 basic tasks of food machinery product quality design of the basic tasks are mainly three: one is to ensure the functional quality of food machinery. The design of food machinery to meet the technical requirements of the functional objectives, to meet the needs of users. Two is to guarantee the quality of food machinery. Make food machinery manufacturing technology to prepare cost, manufacturing cost and the use of the lowest cost, so that the product has a strong market competition ability. Three is to ensure the quality of food machinery technical documents (including drawings). Technical documents should be able to correctly reflect the design ideas and to guide the production of technical requirements. To avoid the poor quality of the product and other loss caused by the design of the drawings. Statistics show that the cost of food machinery products is about 70% of the design decisions, while the proportion of the cost of design work is much less than the cost of manufacturing costs. If the design method of science, the product cost can be greatly reduced.
3, product quality design content
3.1 to collect and analyze the information and quality information is the main basis for the development of new products. It has great influence on the development of new products. Therefore, food machinery manufacturing enterprises should establish the technical information and quality information system, to all kinds of technical information, quality information should be comprehensive, unified management and use.
3.2 to formulate the quality objectives of food machinery product quality objectives should be in full analysis of market dynamics, user requirements, technical level, based on the combination of food machinery manufacturing enterprise quality requirements and strength to develop, and to adhere to the following principles: first, to ensure that in the same class, with its own characteristics. Two is to become the same kind of products, high quality products, with a high level of quality. Three is when can not achieve high-grade products, it should be done in the same grade products in the lowest cost.
