Problems solved by technology

As a traditional and classic detection method, its measurement results are stable and high-precision, and it can be used for calibration of other moisture content detection methods, but it takes a long time to detect, damages the sample, and the detection site is far away from the production machine and equipment. Large volume and other shortcomings, so it is difficult to adapt to the requirements of industrial production for rapid detection of sample moisture content
At present, many manufacturers use infrared measurement technology to quickly detect the moisture content of tobacco products, but the infrared wavelength is short and the penetration depth is shallow, so it can only detect the moisture of the surface product, and the stability of the measurement results is affected by the product color and formula changes. Large impact, need to be checked frequently

Embodiment 1

[0021] In order to test the optimum drying temperature of the flat paper dryer for fast and efficient measurement of the moisture content of the finished product, during the stable production period of a certain type of reconstituted tobacco leaf product by the papermaking method, the slit products are transported to the drying cylinder for drying. By adjusting the rotation speed of the drying cylinder and The steam pressure controls the moisture of the product, and then the product is transported to the cabinet. Under the joint action of the temperature and humidity of the external environment and its own moisture, the moisture of the product reaches a natural balance, and the samples to be tested (40mm×40mm diamond-shaped thin slices, 5 pieces One group, 8 groups in total); set the working temperature of the PL7-C flat paper sample dryer to 110°C, 115°C, 120°C and 125°C respectively, and set the working temperature of the digital display blast drying oven to 105°C; 8 groups o...

Embodiment 2

[0032] According to Example 1, it can be known that the moisture content of the sample can be quickly measured by using a flat paper-like dryer at 120 ° C. In order to find the best drying time at this temperature, the same sample as in Example 1 (40mm * 40mm diamond-shaped finished sheet, 5 pieces) One group, 12 groups in total); set the control temperature of the PL7-C flat paper sample dryer to 120°C (±1°C); number the 12 groups of samples and weigh their mass m 0 (accurate to 0.001g), at a working temperature of 120°C, use a flat paper dryer to dry the sample at different drying times (1min, 2min, 4min, 6min, 8min, 10min), in order to ensure the accuracy of the experimental data , take two groups of samples at each drying temperature for parallel experiments, and use an analytical balance to quickly measure the mass of the dried samples m 1 (accurate to 0.001g); the test results are calculated according to the following formula:

Embodiment 3

[0039] In order to verify that the invention is effective for the rapid measurement of moisture content of different types of reconstituted tobacco products, five different types of reconstituted tobacco products (40mm× 40mm rhombus sample, 5 pieces in a group), in order to ensure the accuracy of the experimental data, two groups of each sample were used for rapid detection of moisture content using a flat paper sample dryer; the working temperature of the PL7-C flat paper sample dryer was set to 120 °C (±1 °C), the working temperature of the digital display blast drying oven equipment is set to 105 °C; number the 10 groups of samples, and weigh their masses respectively m 0 (accurate to 0.001g), put the samples on the drying plate of a flat paper dryer and dry them for 2 minutes, and use an analytical balance to quickly measure the mass of the dried samples m 1 (accurate to 0.001g); In addition, take 2 samples (2-3g, accurate to 0.001g) of 5 different types of products and we...

Abstract

The invention provides a rapid determination method for moisture content in the production of papermaking-process reconstituted tobaccos. The rapid determination method comprises the following steps: taking reconstituted tobacco rhombus-shaped sample slices which subjected to cutting, drying, and naturally moisture balancing in a cupboard; stacking 5 pieces of samples and weighing the mass; setting the control temperature of a flat plate paper sample dryer to be 120+ / -1 DEG C; putting the samples on a drying plane of the flat plate paper sample dryer and drying for 2min; taking out the dried samples and weighing the mass; calculating the moisture content by utilizing a set formula. According to the method provided by the invention, detection equipment can be arranged on a production field and is used for rapidly detecting the moisture content of a product; the rapid determination method has the advantages of simplicity and convenience for operation, short detection time, less demanding quantity of the samples, relatively small errors of detection data and detection results of a traditional drying oven method and high repeatability of measurement results.

Description

technical field [0001] The invention belongs to the technical field of reconstituted tobacco leaf production by papermaking method, and in particular relates to a method for measuring the moisture content of reconstituted tobacco leaf in the production process of reconstituted tobacco leaf by papermaking method. Background technique [0002] The papermaking method reconstituted tobacco leaves is to separate tobacco by-products and tobacco waste into soluble and insoluble substances after soaking and extracting the raw materials according to certain formula requirements. Concentrated and flavored soluble substances are backfilled, and finally dried to make kraft-like reconstituted tobacco products. As a reconstituted tobacco product, the moisture content of paper-making reconstituted tobacco leaves directly affects the product’s inherent smoking quality, filling performance, and storage quality. Many companies regard moisture content as an extremely important quality control ...
