Judging from the weather conditions in recent years, the "El Ni ñ o" phenomenon has become increasingly serious, which calls for our daily life and work to be more from the perspective of energy conservation and environmental protection. With the development of the economy, enterprises pay more attention to how to use the least resources to create more value, which is what all industries need to achieve urgently. The development of the printing industry also follows the trend of energy conservation, recycling and other production links, so the hot-air dryer came into being.

The hot-air dryer, also known as the printing heat pump, works in the same principle as the refrigerator, and works according to the reverse Carnot cycle. The only difference is that the operating temperature range is different. The hot air dryer is a new type of high temperature heat pump developed by using heat pump during product printing and combining the production process characteristics of the printing industry. The unit can realize the combined supply of cold and heat while working, that is, the cold air generated by the heat pump system is recovered while heating, and sent to the workshop to reduce the ambient temperature of the workshop. In this way, the waste heat loss of the printing press can be reduced, and the cooling loss of the workshop can also be reduced. We can kill two birds with one stone and create more value for the enterprise at a lower cost.

The hot air dryer is essentially a heat lifting device, which absorbs part of the heat in the gas discharged from the printing machine, transfers the absorbed heat to the heated object, and re-supplies the working fresh air to the printing machine. The heating heat of the hot-air dryer mainly comes from the sensible heat and latent heat contained in the exhaust of the printing machine. The energy needed to be input is only the power consumption of the drying compressor, and the dryer has the advantage of consuming a small amount of power to produce a large amount of heat. It can automatically adjust the drying temperature of each color group of the printing machine. Therefore, the hot-air dryer is applicable to the drying of printing machines, gravure printing machines, composite machines, coating machines, and the production of products in the curing room; At the same time, it is also applicable to the integrated cold and heat source solution of GMP plants.

Conforming to the green printing recently advocated by the state, the newly planned plants can not use high emission equipment. The hot-air dryer is undoubtedly the best choice for the printing industry. The unit only needs a small amount of electric energy to drive it to achieve a large output of high temperature heat energy and cold air. During the use process, there is little emission and almost no emission. The hot-air dryer is undoubtedly a new type of environmental protection and energy saving weapon in the printing industry in 2016, reducing energy consumption, improving energy value, and greatly improving the market competitiveness of enterprises!
