Problems solved by technology

If the "rot pulp" problem cannot be effectively controlled, it will seriously affect normal production, reduce the recycling rate of white water, and increase the amount of clean water and sewage discharge in the papermaking process
It also cannot meet the water requirements for the production of reconstituted tobacco leaves, thereby reducing the number of white water cycles, cleaning frequency, and increasing the water consumption per ton of the product. It does not meet the requirements of the State Tobacco Monopoly Administration that the water consumption per ton is less than 45 tons and energy consumption is reduced. It is also not conducive to the stability of product quality
[0005] There is no report on the anti-corrosion technology of white water in the paper-making reconstituted tobacco production system. Many reconstituted tobacco production enterprises recycle the white water several times and then discharge it directly, and then replenish it by adding fresh water, which increases the water consumption per ton of product.
However, most of the fungicides used in paper mills in the traditional pulping technology are mostly organometallic compounds, organic bromine and oxidizing fungicides. The use of organometallic compounds has been banned due to their high toxicity and difficulty in decomposing. Organic bromine compounds Irritant, not an ideal choice, and oxidized compounds are easy to corrode equipment, and will consume other papermaking additives, etc. have their own shortcomings
For the special food industry of reconstituted tobacco leaves, the safety requirements are very strict, so it is not feasible to use the traditional pulping and papermaking technology to produce white water deterioration treatment technology for reconstituted tobacco leaves

Embodiment 1

[0017] The white water of the reconstituted tobacco leaf production line by the papermaking method was taken, and the total number of colonies was determined to be 1.0E+07-1.0E+08 cfu / ml through detection. Divide the white water samples into 7 groups, 600mL in each group, and pour them into 7 1000mL sterilized beakers, numbered 1#, 2#, 3#, 4#, 5#, 6#, 7#. Group A was used as a control and placed in a refrigerator at 4°C. Put 2#, 3#, 4#, 5#, 6#, and 7# into the constant temperature magnetic stirrer, and set the temperature at 30°C, 40°C, 50°C, 60°C, 70°C, 80°C ℃, add the rotor (after scrubbing with 75wt% alcohol) and stir evenly. Every once in a while, take out the 1# group sample and compare the smell with the 2#, 3#, 4#, 5#, 6#, 7# group samples, and record whether the sample has deteriorated. After the 1# group sample completes the smell comparison Must be quickly placed in the refrigerator. The above 7 groups of samples were placed with their mouths open. If the water in...

Embodiment 2

[0026] Get the white water identical to embodiment 1, be divided into three parts, each 500ml. The first part is the original white water, and the second part is added with 1ml of diluted bacteriostatic agent (bacteriostatic agent dilution method: take 5ml of bacteriostatic agent with a pipette, add it to a 500ml volumetric flask, and use distilled water to make up the volume. The concentration of antibacterial agent in white water is 1%, that is, 10000ppm), and the concentration of antibacterial agent in white water is 20ppm at this time. In the third part of white water, add 2ml of the diluted bacteriostat, and the concentration of the bacteriostat in the white water is 40ppm. Place three white water samples on a shaker (120rpm, room temperature 20°C) for 4 hours and then take samples to detect the total number of colonies in them respectively. The results are shown in Table 2 below:

...

Embodiment 3

[0031] Take the same white water as in Example 1, and place it in a system environment with a temperature of 60° C., and add 40 ppm of bacteriostatic agent according to the concentration in Example 2. The critical value of the total number of white water metamorphic colonies is used as a node to investigate the time of white water storage in the system environment. The test results are shown in Table 3.

[0032] Table 3 Temperature bacteriostasis and antibacterial agent integration to investigate the deterioration of white water

[0033]

[0034] The investigation results show that the combination of temperature inhibition and antibacterial agent antibacterial method is used to treat the deterioration of white water in production. According to the critical value of the total number of white water deterioration colonies, the treated white water is recycled for more than 20 days, and the total number of colonies is not higher than 5.8. E+07, indicating that the white water d...

Abstract

The invention discloses a corrosion-prevention method for a paper-making process reconstituted tobacco production white water system. The method includes the steps of temperature-control corrosion prevention and bacteriostat corrosion prevention. According to temperature-control corrosion prevention, white water is heated and kept to be 60-100 DEG C, bacteriostats are added into the white water, and the adding amount of the bacteriostats is 20-80 ppm. According to the corrosion-prevention method for the paper-making process reconstituted tobacco production white water system, the method of combining the temperature-control corrosion prevention technology with the bacteriostats is adopted in the paper-making process reconstituted tobacco production process, namely the technology of the combination of controlling the temperature of the white water system to be larger than 60 DEG C and adding bacteriostats to the white water is used as the control means for processing and analyzing microorganisms in the system and is feasible.
