The reporter learned from the Nanjing Agriculture Commission and the Nanjing Power Supply Company on the 11th that Nanjing is vigorously promoting air source heat pump drying technology to improve the quality of grain drying and reduce production safety risks.
Reporters learned that China’s grain has two drying methods: artificial drying and machine drying. The former is limited by the site, weather and other factors, it is easy to cause food waste, drying on the road for the safety of passing vehicles, pedestrians; and in the existing grain dryer, most of the use of coal, diesel, straw, etc. as fuel, There are also disadvantages such as heavy environmental pollution, large potential safety risks, low drying efficiency, low grain drying quality, and high labor costs.
According to the person in charge of the Nanjing Power Supply Company, compared with the above two methods, the use of air source heat pump to dry food costs about 60% of the traditional fuel such as coal; 24 hours operation can effectively guarantee the timely drying of food, guarantee Food production and supply; due to the lack of open fire, safety hazards have also greatly reduced.
Taking the Hewang Agricultural Machinery Service Cooperative in Luhe District of Nanjing City as an example, the five air source heat pump dryers put into operation in 2016 have an annual grain drying capacity of about 8550 tons and a grain drying cost of about 35 yuan per ton. The cost of coal-fired drying equipment is about 21 yuan, and annual savings are about 120,000 yuan; the use of air-source heat pump technology to replace coal-fired hot blast stoves, reduce carbon dioxide emissions by about 4,200 tons, reduce emissions of sulfur dioxide by about 10 tons, and reduce nitrogen emissions. About 12 tons of oxides and dust.
Since last year, Jiangsu Province has piloted the use of air source heat pump electric drying equipment in Nanjing to replace the original coal-fired hot blast stove. Up to now, Jiangsu has cumulatively promoted about 300 sets of air-source heat pump food and electric drying equipment, and the daily grain drying capacity reached more than 6,000 tons. As the autumn harvest is approaching this year, Nanjing will further promote air source heat pump technology and comprehensively promote the replacement of electrical energy in the agricultural production field.
The ion exchange resin works through a process known as ion exchange, where it replaces undesired ions in the water with more desirable ones. This resin is typically made up of small, porous beads that contain charged functional groups.
When water passes through the pressure tank containing the ion exchange resin, the resin beads attract and retain the unwanted anions and cations present in the water. These unwanted ions, such as calcium, magnesium, iron, and sulfates, are exchanged with more desirable ions like sodium or potassium.
The exchange process occurs as the water flows through the resin bed, allowing the resin beads to selectively trap the unwanted ions and release the desired ions. This effectively removes the minerals responsible for water hardness and replaces them with softer ions, resulting in softened water.
Softened water offers various benefits, including preventing scale buildup in pipes and appliances, improving the efficiency of water heaters, reducing soap scum and residue on surfaces, and providing better lathering and cleaning capabilities.
It is understood that Nanjing is vigorously promoting air source heat pump drying technology to improve the quality of grain drying and reduce production safety risks. Up to now, Jiangsu has cumulatively promoted about 300 sets of air-source heat pump food and electric drying equipment, and the daily grain drying capacity reached more than 6,000 tons.
