Analysis on the healthy use of stainless steel kitchenware and chromium release

Since the environmental inspection is very strict now, many catering companies and canteens have installed oil fume purifiers. It was thought that after installing the oil fume purifier, the oil fume purification rate could be improved and the environmental impact assessment could be passed smoothly. However, some users found that after installing the oil fume purifier, the kitchen fumes were still not purified and still could not pass the environmental impact assessment. So, what is the reason for the unsatisfactory purification effect after installing the oil fume purifier? As a professional manufacturer of commercial kitchen utensils and kitchen equipment, we have many years of experience in the installation and sales of oil fume purifiers, and now we will share the relevant knowledge with you. As a professional manufacturer of commercial kitchen utensils and kitchen equipment, we believe that the main reason for the poor effect of the oil fume purifier is the following: 1. The quality of the purification equipment itself is not up to standard. The oil fume purification equipment market is mixed, and the oil fume purifier can be purchased for a few hundred yuan. Take this type of oil fume purifier as an example. It is low-cost and simple in materials, not to mention the technology. It may have some effect when it is just installed, but it will be scrapped in a few days. Therefore, when buying an oil fume purifier, don't be greedy for cheapness, and choose products tested by environmental protection testing agencies. If you decide to buy, you must have a detailed and comprehensive understanding of the supplier of the oil fume purifier. Here is a reminder that oil fume purifiers are generally divided into low-altitude emissions and high-altitude emissions. Among them, the purification efficiency of oil fume purifiers with high-altitude emissions is often low, only about 20%-40%. According to the existing national standards, the removal rate of oil fume purifiers installed by catering companies must be at least 80%! When purchasing, you must choose according to local environmental protection emission standards. 2. Inadequate cleaning and maintenance or equipment failure. Due to the harsh working environment of the oil fume purifier itself, if it is not cleaned and maintained for a long time, the purification efficiency is bound to decrease, and more seriously, there will be failures, damage to the machine, and even fire hazards. Therefore, everyone should clean and maintain the oil fume purifier regularly, and ensure that the cleaning cycle is not too long. If the equipment fails, you should find a supplier or a professional master to check and repair it to avoid safety accidents. 3. The air volume does not match. The size of the restaurant kitchen, the number of stoves used, and the main cooking cuisine are also different. These will affect the actual amount of oil fume generated. For example, some large-scale restaurants use oil fume purifiers that can only handle 4000m3/h of air volume. The result of oil fume emission can be imagined. Therefore, the specific specifications of oil fume purifiers to be used need to be determined based on the actual exhaust volume of the restaurant. If you are not sure, you can consult the purifier supplier before purchasing, and try to ask them to visit the site to provide more professional and efficient oil fume purification solutions.
