Why bearing health design is crucial to food security

The problem of designing health food machinery plays an important role to control food security. However, without considering the sanitary equipment parts design, rather than broad application of this concept, it could cause bearing inner bacteria breeding ground for the risk of transmission, Davide Zanghi, SKF health design, director of the office said. Health design should consider the specific factors ( Such as corrosion, leakage of lubricants, cleaning and drying) automatically The adverse impact on food safety, and using the suitable design principle to solve the problem. In essence, it is a USES certain principles and design ideas. As with human body engineering design focus on the user's physiological needs, health design is focused on preventing food contamination problem. The European Union for sanitary engineering and design ( EHEDG) Aims to improve the sanitary engineering design standards, in order to promote its members ( Including equipment manufacturers, food enterprises and research institutions) The safety of the food production capacity, SKF join EHEDG since 2006. In November 2016, the alliance held once every two years in Denmark's world congress, SKF at the conference, again emphatically illustrates the application of these design principles of a long tradition. Design principles - Seriously bearing components under normal circumstances, the EHEDG guidelines that easily trapped food particles and water in bearing, therefore, the bearing is seen as a harbor potential a hotbed of bacteria. General advice is to ensure that the bearing from food contact area. This proposal is very much in the health food industry belt conveyor design standards of the latest, EHEDG attention in this field both in the security of food production major challenge: how to avoid contamination of food by improper processing equipment design, and how to don't improve clean production and the health of the operating costs at the same time to improve food safety. In fact, people in the health of the whole system design mainly focuses on the system and the main components ( Such as belt) ； But often the bearing and the bearing unit. However, even if the bearing is not direct contact with food area, they are often near the food, and a high pressure water or dry cleaning system. Thus, if the presence of bacteria, it is possible to spread through the air, and contaminated food. In order to minimize the risk of contamination and health should be fully considered during the design bearing design principles. One of the most important principle and constitution health design is effective cleaning ability. It is easy to understand, but in practice for bearing and the bearing units are often not easy. First of all, the product should be used in the corrosion resistance and non porous materials ( Such as stainless steel) Or composite materials, and appearance is easy to clean, stop moisture can automatic emptying. Bearing unit should have filled the base to avoid leave gaps breeding ground for bacteria. In general, such as elastomer, and grease composite materials should comply with the instructions and regulations on food safety. In all cases, should try to avoid grease leak to food during operation. Is the best way, bearing unit is equipped with high end cover, prevent pollution and clean liquid from entering the bearing inner cavity, at the same time allow visual check regularly. Other related areas including: in the unit components and adherent surface should avoid as far as possible avoid metal to metal contact between supplement lubrication under very strict operation and cleaning systems still achieve long life health design completely suitable for food production and packaging machinery. But the bearing is one of the many problems parts, solve the problem of bearing is the first step to improve overall risk strategy.
