Air fryers use hot air circulation to cook food that would otherwise be soaked in oil. The cooking chamber of an Air Fryer radiates heat from heating elements near the food for more efficient cooking. A fan is usually used to circulate hot air around the food. The opening at the top is used to draw in air, while the exhaust at the back controls the temperature by releasing any unwanted hot air. It is also used to offset any increase in internal pressure. Internal temperature may be as high as 230°C (445°F) depending on model. For your safety, do not put oil in the fryer or place flammable items near the fryer. Typically, cooking time in an air fryer is reduced by 20% compared to a conventional oven. This will vary by brand and the amount of food cooked in the air fryer. 1.5L-4.5L Air Fryer,Air Fryers,Air Fryer Digital,Small Air Fryer Guangxi Nanning King Green Smart Co., Ltd. , https://www.smartliferobot.com
The current hot spots in the domestic environmental protection market are: urban sewage treatment equipment, recycled water (recycled water) reuse equipment, coal-fired flue gas desulfurization and denitrification equipment, municipal solid waste treatment equipment, and hazardous waste (including medical waste) treatment equipment. In addition, with the advancement of circular economy, the development of technical resources for comprehensive utilization of resources will accelerate and become a new area with great potential for environmental protection machinery manufacturing. Recycling of waste household appliances and electronic products, control of micro-pollution of drinking water, control of volatile organic pollution, prevention of soil pollution, and many areas of clean production will be new development opportunities for environmental protection machinery.
In the coming period, the chemical environmental protection equipment manufacturing industry should increase the development and promotion of corresponding technical equipment in a targeted manner. This will not only meet the general trend of building green chemicals in China, but also provide a new huge space for the further development of the company itself.
Compared with industrial developed countries, there are still large gaps in China's chemical environmental protection technologies, mainly manifested in high-concentration, hard-to-biochemical organic wastewater treatment technologies, incineration technologies, research and application of high-efficiency strains for biochemical treatment, and monitoring. Instrumentation and so on. Because the pollutants discharged from chemical production vary widely, it is difficult to control them with one or two methods. As an important content of chemical environmental protection technologies, the performance of major domestic chemical environmental protection equipment needs to be further optimized. In addition, the chemical environmental protection equipment manufacturing industry also needs to increase the proportion of high-tech products and complete sets of major technical equipment, advance key technology innovations, and develop urgently needed, high-efficiency and low-cost environmental protection technology and equipment for the chemical industry.
Among the environmental protection equipment encouraged by the government in the future, the major related to the chemical industry are:

It is understood that the chemical industry is one of the major industrial pollution. According to the 2006 Environmental Statistics Annual Report issued by the State Environmental Protection Administration, chemical wastewater discharge accounts for 19% of the total industrial wastewater discharge in the country, ranking first; exhaust emissions account for 7% of total national emissions, ranking No. Three; Solid waste production and emissions accounted for 7% and 1.6% of total solid waste production and emissions, ranking fourth; sulfur dioxide emissions ranked third; dust, dust emissions ranked fourth The number of cyanide, petroleum, sulfide, and arsenic emissions ranked the first; suspended solids and mercury emissions ranked second; volatile phenols and lead emissions ranked third. Environmental issues have, to varying degrees, constrained the sustainable development of the chemical industry.
Environmental protection equipment provides support for green chemicals
In recent years, the domestic demand for environmental pollution prevention and control has increased by a large margin, which has led to the growth of environmental protection machinery manufacturing industry. The average annual industrial output value of the whole industry has increased by more than 15%, and some key enterprises have increased by as high as 37%. Among them, the output of water pollution prevention and control equipment increased by 6 times in 2006 compared with that of the previous year. The output of solid waste treatment equipment increased by 31.18%. The output of environmental monitoring equipment reversed the negative growth in 2005. Only the output of air pollution control equipment was 19.64%. %Negative growth. At the same time, the export of environmental protection equipment maintained rapid growth, but the import amount was still greater than the export value.
