Situation paper tube manufacturer of high temperature heat pump is used in paper tube drying aspect is developed in recent years, has been carried out before drying with traditional electric heating, boiler, microwave or high-frequency equipment, however, all of these are is the traditional way of drying or high energy consumption and high pollution, to respond to the trend of energy saving and environmental protection, it is clear, after all, will be eliminated, although the current situation is difficult to change the existing dry state, but in this increasingly fierce market environment , reduce production costs, enhance their market competitiveness, is in urgent need of every business faces, and high temperature heat pump drying equipment used in paper tube packaging enterprise, greatly reducing the cost of doing business in the production of paper tube. Second, the high-temperature heat pump dryer drying principle is the use of reverse Carnot principle, absorbing heat from air and transfer it to the room, drying room temperature to achieve improved, with the appropriate equipment to achieve dry materials. Compressor heat pump dryer - heat exchangers (machine) - Chokes - heat sink (outside the machine) - Compressor and other devices constitute a circulatory system. Under the action of the compressor in the refrigerant circulating in the system flow. It is done in the compressor gaseous boost heating process (temperature up to 100 ℃), releasing it into the machine dry in room temperature air heated by the heat, while they have been cooled and converted to liquid flow, when it runs to the outside of the machine After the liquid evaporates quickly transformed into gaseous again, while the temperature dropped to minus 20 ℃ --30 ℃, then the air around the heat sink will continuously transfer heat to the refrigerant. Refrigerant continuous cycle to achieve the heat in the air transport to the drying room heating room air temperature. Three: paper tube heat pump drying unit Model: four: Comparison of various energy heating equipment: five, heat pump drying characteristics: high temperature heat pump dryer is an environmentally friendly energy-saving drying equipment, drying process does not produce any harmful substances, will not produce a fire, the unit is running at normal temperature and pressure, the biggest feature is reflected in energy efficiency, energy saving 60% energy saving compared with infrared heating pipes, etc., than burning oil saving 40% energy saving than coal 20% to 30%, and the cold air generated in the drying process, improve the workshop working environment. Drying methods can be made in the form of tunnel drying line, pipeline drying method can also be made, but can be made in the form of drying room, depending on the specific needs of enterprises to customize. The drying models by industrial plants and chemical fiber paper tube paper tube manufacturers repeatedly drying practices and test data, and accumulated a wealth of experience in drying, combined with theoretical calculations based on a complete and practical, to ensure that the paper tube drying The precise shape during hardness, perpendicularity, roundness, moisture content, so that each hot air circulation through the internal part of the internal heat evenly, and the drying process can be set according to a suitable temperature different thicknesses of paper Paper different specifications and running speed drying. Which models have been tested by thousands of times and proved, in environmental protection, energy conservation, safety, intelligent control has been a strong verification. The company will continue to improve through continuous efforts constantly updated, and strive for enterprises to design the most perfect, the most practical industrial drying equipment.
