Description
Technical Field
The utility model relates to a tobacco processing technology field, in particular to mould proof equipment is guaranteed quality to piece cigarette radio frequency.
Background
Tobacco leaves are used as raw materials of the tobacco industry and are subjected to primary baking → threshing and redrying → storage of tobacco flakes → alcoholizing fermentation → cigarette formulation → cigarette filament making → cigarette rolling → cigarette packaging → sale. The tobacco flakes are damaged by mould during the storage, alcoholization and fermentation processes. The mould can reduce the loss of tobacco leaves in the processing period, and the mould can completely prevent the tobacco leaves from being used. The mold is widely present in the air of the nature, and the tobacco leaves and tobacco shreds are mainly provided with aspergillus, mucor and penicillium fungi. After the tobacco leaves go mouldy, the tobacco leaf contents are rapidly decomposed, normal structures and contents are damaged, the appearance color is dark, the original fragrance disappears, strong mouldy acid odor is emitted, the taste is seriously deteriorated, the irritation is increased, the tobacco leaves are bitter and dry when being sucked, the tobacco leaves cannot enter the throat, the toughness and the elasticity of the tobacco leaves are greatly reduced, and when the tobacco leaves are seriously mildewed, the tobacco leaves are completely changed into black, dirty and stinky rottenness substances, the use value is lost, and great loss is caused to producers. According to statistics, the tobacco leaf loss caused by the mould in China is 1.9 percent and can reach 6 percent at most every year, and the mould proof work is the most important factor in the tobacco storage process. The environmental humidity, the temperature and the moisture content of the tobacco lamina are three major factors influencing the mildew of the stored tobacco leaves, wherein the humidity is the leading factor, and the moisture content of the tobacco lamina in a tobacco box or a tobacco bale can be increased due to high environmental humidity. Research shows that under the same temperature condition, the moisture content of tobacco leaves is in the safe storage moisture content range, the tobacco strips can be safely stored without mildewing, and the moisture content exceeds the safe storage moisture content standard, so that the mildews are easily bred, and the tobacco strips are mildewed. Therefore, whether the piece of tobacco can keep the safe moisture content of storing or take off the moisture that surpasss the safe moisture content of storing in the smoke box fast in the smoke box becomes the key that the piece of tobacco keeps the quality, prevents to take place to milden and rot.
In the prior common tobacco leaf quality-guaranteeing and mildew-proof technology, the traditional physical mildew-proof method comprises methods such as ventilation, sealing and oxygen reduction, the ventilation can reduce the temperature and humidity of a tobacco warehouse and prevent the tobacco leaves from mildewing, but in continuous rainy seasons or foggy seasons, the ambient air humidity is high, and the effect is not obvious; the large-scale dehumidification and temperature control equipment is adopted to adjust and control the storage warehouse to keep constant temperature and constant humidity, so that the tobacco flakes can be effectively prevented from mildewing, and the lower temperature is unfavorable for tobacco mellowing due to overhigh construction and operation cost of corresponding storage facilities; the storage space air-conditioned storage technology can also avoid or reduce the mildew of the tobacco flakes, but the sealed oxygen reduction does not utilize tobacco leaf alcoholization fermentation because alcoholization fermentation is carried out during the storage of the tobacco flakes, thereby influencing the quality and subsequent use of the tobacco flakes. The mildew of the stored tobacco flakes can be avoided or reduced by performing mildew-proof treatment on the stored tobacco flakes by using a chemical mildew-proof medicament or a biological agent, but the problems of limited use place and range, weak sterilization capability, residual toxicity and the like exist. Radiation, ozone mildew prevention and other technologies have the defects of being not beneficial to environmental safety, influencing tobacco mellowing, appearance quality and the like to different degrees. In the physical sterilization technology, microwaves have the advantages of certain penetrability, selective heating and the like, the sterilization and anti-mildew effect on the tobacco flakes is obvious, and the processing manufacturability and the quality can be improved.
Therefore, the method for rapidly removing the excessive moisture of the tobacco flakes in the tobacco box and effectively killing the mold becomes the key for preventing the tobacco flakes from mildewing, and the technology for overcoming the defects of the method and effectively preventing the tobacco leaves from mildewing is urgently needed in the storage and production of the tobacco flakes in the tobacco industry.

specifically, the tobacco boxes 1 to be subjected to quality-guaranteeing and mildew-proof treatment are continuously loaded on a conveyor belt of a tobacco sheet conveying system 2 through material loading and unloading equipment, the seals of one layer with higher water content in the tobacco boxes are upwards placed, a tobacco box upper cover 4 sealed on one side (above) with higher water content in the tobacco boxes is opened through tobacco box opening equipment 3, pad paper above the tobacco blocks in the tobacco boxes is taken out, and the tobacco blocks in the tobacco boxes are exposed in the air and then conveyed into a radio frequency quality-guaranteeing dry mildew-proof treatment cavity 5.
After the tobacco box 1 enters the radio frequency quality-guaranteeing dry mildew-proof treatment cavity 5, polar molecules and charged particles in the tobacco flakes generate oscillation and migration after receiving radio frequency electromagnetic wave energy generated by the radio frequency generator 7, electric energy is converted into heat energy, the tobacco flakes are heated to kill mildew in the tobacco flakes, and meanwhile, water exceeding the safe storage water content in the tobacco flakes is vaporized and discharged out of the tobacco box and is discharged out of the radio frequency quality-guaranteeing dry mildew-proof treatment cavity 5 through the moisture discharging system 8. In the radio frequency quality-guaranteeing drying mildew-proof treatment cavity 5, in order that the surface temperature of the smoke box 1 is not too low to influence mildew-proof treatment and drying of the tobacco sheets in the smoke box, auxiliary hot air is blown to the smoke box 1 through the hot air spray pipe 6, so that the smoke box is kept at a proper temperature in the quality-guaranteeing drying mildew-proof treatment process. In the radio frequency quality-guaranteeing drying and mildew-proof treatment cavity 5 of the cigarette box 1, the tobacco flake layer with higher water content is located above and exposed in the air, in order to accelerate mildew-proof treatment and drying and dehydration of the tobacco flake, auxiliary hot air is blown to the tobacco flake layer with higher water content at the opening of the cigarette box through the hot air spray pipe 6, so that surface moisture evaporation is accelerated after the tobacco flake layer is heated, and rapid discharge of internal moisture is facilitated. The temperature of a high water content area of the tobacco slice in the tobacco box 1 reaches the mould death temperature and is kept until the mould death time, and the quality-guaranteeing and mould-proof treatment requirements are met when the water in the high water content area is discharged by heating diffusion and falls within the preset safe storage water content range.
The processed quality-guaranteeing and mildew-proof processed smoke box 13 meeting the quality-guaranteeing and mildew-proof processing requirements is conveyed into a cooling cavity 10, low-temperature air generated by a low-temperature air generator 9 is blown to the quality-guaranteeing and mildew-proof processed smoke box 13 through a low-temperature air spray pipe 11, the temperature of the smoke box and the tobacco sheets in the smoke box is quickly reduced to a specified temperature (safe in storage and beneficial to alcoholization and fermentation), the opened smoke box upper cover 4 is sealed and sealed again through a smoke box sealing device 12, and the smoke box is unloaded by a loading and unloading device and is conveyed to a preset position in a storage warehouse.
Therefore, in the radio frequency quality-guaranteeing and mildew-proof method for the tobacco lamina, radio frequency (electromagnetic wave with the frequency of 3 kHz-300 MHz) can penetrate into the tobacco box, electric energy is converted into heat energy to heat the tobacco lamina to the mildew death temperature, and the mildew-proof treatment effect is achieved; in the radio frequency treatment process, radio frequency energy concentrates on relatively that local water content is higher, easily breed the region that the mould produced and milden and rot, and this region is fast in low water content region because of accepting the relative concentrated heating of radio frequency energy, and the temperature is far above low water content region, and mould selective heating advantage in to the sheet tobacco makes the higher regional water content of water content descend fast to can not take place to milden and rot predetermine safe storage water content scope. In the radio frequency treatment process, the temperature of most of the tobacco flakes with relatively low water content (the water content is in the safe storage water content range) in the controllable tobacco box can not be raised too high, the high temperature which influences the quality of the stored tobacco flakes can not be generated, and the small temperature rise in the reasonable range is favorable for alcoholization and fermentation of the tobacco flakes, so that the quality is improved. The radio frequency treatment process has the advantages of no radiation leakage, small equipment investment, capability of penetrating the tobacco carton packaged by the tobacco sheets into the tobacco sheets, convenience, contribution to production and application and the like.
