It is understood that the material drying process is a huge energy-consuming process. According to statistics, the energy consumed for drying in most developed countries accounts for 7%-15% of the national total energy consumption, while the thermal efficiency is only 25%. -50%, and most drying processes, especially heat-sensitive materials (such as food and biological materials), have an impact on their color, nutrition, flavor and texture. The heat pump drying technology has the advantages of low energy consumption, small environmental pollution, high drying quality and wide application range, and its excellent energy-saving effect has been proved by various domestic and foreign research institutes.
Conventional drying oven drying uses electricity or steam to heat the air to reduce the relative humidity of the air. After the heated air absorbs the moisture of the dried material, a small part flows back in the box, and most of the air is drawn directly by the exhaust fan. Going to the environment, obviously a lot of heat energy is lost in the exhaust process. If the water vapor in the exhausted air can be condensed to below its saturation temperature, it can be condensed into water and drained, and its latent heat and dry air can be recycled, the drying efficiency will be greatly improved. Heat pump technology for drying.
The use of heat pump technology to dry materials is a new drying method that has been developed in recent years with significant and effective energy savings. The use of a heat pump drying box has the advantages of high efficiency and energy saving, and the power consumption thereof is only one fourth to one third of the power consumption of a general electric drying oven. The drying temperature of the heat pump drying box in the drying process is relatively low, which is particularly beneficial to the drying of materials that cannot withstand high temperatures, such as the drying of materials such as fungus, shiitake mushrooms, Chinese medicinal materials, and some heat-sensitive chemical raw materials.
In the drying process of the heat pump drying box, since circulating air circulates only in the drying box, there is no need to pump gas to the outside of the drying box, so the pollution to the surrounding environment during the drying process is greatly reduced. The experimental results show that in the drying process of the heat pump drying oven, the difference between the temperature and the relative humidity in the drying chamber is the maximum between 1 and 2.5 hours of drying. At this time, the heat pump drying box also has the largest amount of water removal.
As an important material basis for the national economy, energy directly affects the sustainable development of the country. At present, almost all industries including agriculture, chemical industry, medicine, and wood processing include drying processes. Drying has become a key link in improving product quantity and quality during the production process. However, the drying process is also a process of high energy consumption. Therefore, the development of new dry methods, new products, and new processes with low energy consumption, environmental friendliness, and guaranteed quantity and quality of products is of great significance for today's energy scarcity.
A heat pump is a heat energy device that absorbs heat from a low-temperature heat source and uses it as effective heat energy at a relatively high temperature. Compared with other drying devices, the heat pump has high thermal efficiency, energy saving, low drying temperature, and high dewatering efficiency. Features such as hygiene and safety have a broad market space.
It is reported that the heat pump dryer of Changzhou's unified drying R&D production has the advantages of high efficiency, environmental protection, environmental protection and non-pollution, and safe and reliable operation. According to reports, the device consumes only a small amount of electric energy and can absorb a large amount of heat in the air. The power consumption is only 1/3-1/4 of that of the electric heater. Compared with coal-fired, oil and gas water heaters, Can save about 75% of operating costs. 1 kWh equals 4 kWh. This device is a sustainable and environmentally friendly product without any burning or emissions during use. In addition, the entire system operates without the danger of flammable, explosive, poisoning, short circuit, etc. that may exist in conventional dryers (fuel, gas, or electric heating), and is an absolutely safe and reliable semi-closed drying system. The equipment is highly automated and intelligent and can be continuously dried for 24 hours. Widely used in food, chemical, pharmaceutical, paper products, leather, wood, agricultural and sideline products processing and other industries heating and drying operations.
