Continuous microwave paper straw rolling drying and sterilizing equipment and working method thereof

Abstract

The invention discloses continuous microwave paper straw rolling drying and sterilizing equipment and a working method thereof. A box body includes a drying cavity, a paper straw conveying device is arranged in the drying cavity, one or more microwave transmitting devices are arranged on the upper part of the drying cavity, and the paper straw conveying device drives single paper straws to advancein a rolling mode; microwave outlets of the microwave transmitting devices communicate with microwave pipes, the microwave pipes are connected with transitional turning waveguides, the transitional turning waveguides are connected with slot antenna waveguides parallel to the sections of conveying chains, and microwave energy is evenly fed into the paper straws on the conveying chains located below the slot antenna waveguides; and the continuous microwave paper straw rolling drying and sterilizing equipment further comprises a sensing system and a controller system, and the controller system controls the start-stop states and adjustment of the microwave transmitters, the paper straw conveying device and the sensor system. Comprehensive and oppression-free all-dimensional even drying of thepaper straws is better achieved, the phenomena that the paper straws have drying dead angles, and drying is uneven and not thorough are reduced, and the problems of deforming and cracking of the paper straws due to stacked drying are reduced.

Description

technical field [0001] The invention relates to the field of paper straw drying equipment, in particular to a continuous microwave paper straw rolling drying and sterilization equipment and working method specially for paper straws. Background technique [0002] Due to the paper straw rolling process, water-based environmental protection latex must be coated on the paper, and its water content is relatively high. The 8-10% moisture content of the paper before rolling the tube will become 16-18% after the glue is coated on the tube. If it is not dried evenly, the paper and the tube are easy to crack, degumming and deformation. After a long period of storage or closed transportation, there will be problems such as discoloration and mold. After the paper tube is formed, it has a hollow structure and is stacked. The traditional heat conduction drying method is very slow, the internal and external temperatures are inconsistent, the external moisture evaporates quickly, and the i...

AI Technical Summary

Problems solved by technology

After the paper tube is formed, it has a hollow structure and is stacked. The traditional heat conduction drying method is very slow, the internal and external temperatures are inconsistent, the external moisture evaporates quickly, and the internal evaporation is slow. In addition, in mass production, it is easier to cause dead corners, unevenness, and incomplete phenomenon

If it is dried at high temperature for a long time, the paper straw will be deformed and cracked, and energy and manpower will be wasted.
