What are the shortcomings of the traditional moisture measurement method for waste paper bags? What measurement methods can be substituted?

Sampling, drying and weighing method is a traditional method to measure the moisture content of waste paper bags. In this method, one to two kilograms of samples are taken from a ton of waste paper bag, then put into a drying room for drying, and finally the weight after drying is divided by the weight before drying. Get the moisture content. Used to indicate the moisture value of all batches of paper. This sampling, drying and weighing method has many disadvantages:

1, the drying room needs to consume a lot of electricity every year (the annual power loss is as high as one million yuan).

2, need a lot of manpower to participate in sampling inspection.

3. It takes as long as six to eight hours to get the moisture value.

4. It is easy to be manipulated by human beings, resulting in a black hole in purchasing.

5, a small amount of sampling, can not represent the overall moisture.

2. Hand-held instrument contact measurement. This method uses plug-in or flat measurement to measure the part of paper packaging.

MS-590 is a multi-spectral microwave water meter, which is specially designed for paper mills and packaging stations to measure the moisture content of waste paper vehicles and packages. It adopts electromagnetic wave penetration measurement mechanism. It can realize non-contact and unmanned on-line real-time measurement of the average moisture content of waste paper in the whole car and package. MOSEY multi-spectral microwave water meter can realize the following functions:

1. You can measure the average water content of the whole vehicle's waste paper in real time without stopping. There is no need to unload, stop, extract or open the package.

2. Without manual participation, the whole water measurement process is automatically completed and the water measurement result is automatically obtained. Minimize human interference and realize unmanned settlement.

3. Fair, just, transparent and fast measurement greatly improves the collection efficiency.

4. When measuring a single bag, you can find the location of the wet bag with water in the single bag, so that those who seep and inject water have nowhere to hide.

5. Have a complete set of waste paper acquisition management system, which can provide a complete set of acquisition management system for paper mills, including weighing, water withholding, impurity deduction, grading and automatic settlement.
