Traditional paper bag drying equipment technology can not meet the needs of production enterprises, while the new paper bag microwave drying equipment heating fast, uniform, effective evaporation of moisture in paper bags, will not cause local drying, effectively ensure product quality, while saving energy consumption, energy utilization rate can reach 80% or more, improve enterprise efficiency.
Microwave drying equipment uses microwave to heat paper bags as a whole in a non-contact way. Microwave can directly penetrate the material, be absorbed by polar molecules in the material, rapidly raise the temperature, without heat conduction, no heat conduction loss and rapid heating. Microwave heating makes the surface of the material heated uniformly at the same time, without thermal gradient, and will not cause dry cracking of the product due to uneven heating. Deformation and other phenomena to improve product quality.
Microwave drying equipment only uses electric energy to convert microwave energy to heat paper bags. There is no other energy, crucible, furnace body and so on. The energy utilization rate can reach 80% or more, which saves more than 1/3 of energy than infrared heating. The equipment adopts tunnel structure, mainly made of stainless steel plate, with strong heat insulation and insulation performance, less heat overflow, good working environment and energy saving. The equipment has high degree of automation and can be operated continuously by using PLC automatic control. Microwave power adjustable, automatic temperature control, transmission frequency conversion speed regulation, materials can be dried in a few minutes, labor intensity is small, only 2-3 people. Characteristics of kraft paper drying equipment:
1. Conventional drying equipment is heated by steam, which needs heating from inside to outside. Slow heating speed needs to consume a lot of coal. Microwave drying equipment uses electromagnetic wave heating, which does not need heat transfer medium, directly heating to the inside of the object. The heating speed is fast. Microwave energy of 1 kilowatt can be heated at room temperature in 3-5 minutes. Water is heated to 100 C, which avoids the shortcomings mentioned above. Therefore, it has the advantages of high speed, high efficiency, shorter drying period and lower energy consumption. Compared with conventional drying technology, it can increase work efficiency more than four times.
2. Microwave drying equipment is uniformly heated from inside to outside at the same time. The temperature difference between inside and outside of the material is very small, and there will be no inconsistency between inside and outside heating in conventional heating.p>3. Microwave drying equipment is easy to control, which is convenient for continuous production and automation. Because microwave power can be adjusted quickly and without inertia, it is easy to control in real time, and it can adjust temperature arbitrarily between 40 and 100 degrees Celsius. Liwei microwave equipment
4, small size, easy installation and maintenance, do not need to occupy too much space. Microwave drying equipment has the efficacy of disinfection, sterilization and insecticidal eggs, and the product is safe and hygienic. Long shelf life.
6. The economic benefit of microwave drying equipment is remarkable. Traditional drying takes a long time, slow speed, high energy consumption and high processing costs. Microwave heating can save a lot of energy and improve the speed of heating and drying. This is because microwave has penetrability. When heating an object, it does not need any media, and it can heat both inside and outside the material at the same time. According to the data at home and abroad, the speed and efficiency of heating materials with microwave equipment is 4-20 times higher than that of conventional heating methods.
paper bag microwave drying equipment has high utilization rate of heat energy and low operation cost. It provides various types of drying equipment selection schemes and budget quotation. This article is from the microwave drying equipment () network.
