Description
Technical field
This utility model relates to cabo technical field of processing equipment, especially relates to a kind of raising Microwave expansion tobacco stem yield
Device with quality.
Background technology
Cabo accounts for the 25%~30% of tobacco leaf weight, owing to cabo has a similar component to Nicotiana tabacum L., and has and improves cigarette knot
Structure, reduction cost and the function of lowering harm and decreasing coking, be therefore the important component part of raw material of cigarette.Research shows, at microwave expansion
Reason can promote the decomposition of cell wall substance in cabo and the increase of aroma component, significantly improves the volume of cabo and changes cabo
Internal organizational structure, when applying as raw material of cigarette, its suction quality and feed liquid absorbability are all substantially improved, this be thread,
The granular exploitation application waiting cabo goods and production and processing, it is provided that good basic material.But, due to towards commercial production
Low cost cabo microwave bulking processing equipment technology Shortcomings, seriously constrain Microwave expansion tobacco stem scale application.
The utility model patent of Application No. 03233590.3, discloses many wave source multi-feed port microwave tobacco stem expansion devices,
The suppression on power supply, heating compartment, feed inlet and outlet and feed inlet and outlet is driven including what microwave magnetron was connected with microwave magnetron
Section, is provided with multiple microwave magnetron being connected with excitation cavity in the bottom of heating compartment, after cabo charging aperture suppression section
End is provided with preheating section;Meanwhile, the front end in cabo discharging opening suppression section is provided with soaking zone.This device is actually in belt
Increase microwave radiation cavity on the basis of feeder equipment, utilize microwave radiation that the cabo on belt feeder equipment is expanded, merit
Rate density is low and uneven, and expansion effect is poor.
The utility model patent of Application No. 201210119828.X discloses a kind of microwave expansion using gas heating agent
The method of cabo, it is proposed that increase microwave radiation cavity on foraminous conveyer, and be passed through 90 DEG C~300 DEG C in microwave cavity
Gas heating agent, implements gas, the method for microwave combined expansion to cabo.This patent there is a problem in that 1. foraminous conveyer
Employing polytetrafluoroethylmaterial material is made, owing to politef heat-resisting quantity is poor, in gas heating agent and microwave radiation synergy

Static by microwave radiation cavity so that it is uneven and cause cabo expansion lack of homogeneity that cabo accepts microwave radiation;3. paving
Have between the guipure of cabo and microwave source and devise the stainless steel cage having bar seam, cause and easily occur that microwave leakage is unmanageable
Problem.
The utility model patent of Application No. 201110138821.8, discloses a kind of roller type tobacco stalk continuous microwave expansion
Equipment, it is proposed that rotate at one and increase the device of microwave radiation cavity outside material conveying cylinder, by this device is tilted cloth
Put, drive the internal cabo passed through constantly to move when cylinder rotates, and in cylinder, accept microwave radiation, thus it is micro-to improve cabo
Ripple expands uniformity and swelling degree.This patent there is a problem in that 1. owing to wave is good, machining intensity high and becomes
This most relatively low material is less, large scale can rotate material conveying cylinder and manufactures difficulty in applied microwave radiating enclosures, cause equipment
Yield (below 1000k/h) is relatively low;2. in formula cabo microwave expansion production process, by length, form (stalk turns) etc.
Impact, different tobacco stalk raw material density variations are bigger so that formula cabo stirs uneven in rotating cylinder, the microwave spoke of acceptance
Penetrate uneven, often lead under equal-wattage, easily occur expanding lack of homogeneity with a collection of formula stalk and carbonization occurs in part cabo
Phenomenon;3. large scale rotates sealing and the microwave leakage control relative difficult of cylinder.
The utility model patent of Application No. 201510500823.5, discloses a kind of microwave continuous, quick, safe cigarette
Stalk bulking equipment, including microwave bulking device housings, microwave emitter, microwave bulking equipment inner chamber, feeding screw, microwave bulking
The entrance point of equipment inner chamber connects feeding seal cabin, and the port of export connects discharging sealed compartment, is provided with spark and visits in microwave cavity
Surveying device and carbon dioxide extinguisher, microwave emitter connects outer circulation cooling water system.This patent there is a problem in that

Low, poor rigidity, causes and is difficult to manufacture and relatively costly with large scale polytetrafluoroethylene wave-permeation supporting body, in turn result in microwave expansion
The production capacity of equipment is relatively low (below 1000kg/h);Even if 2. producing large scale polytetrafluoroethylene material by modes such as splicings
The microwave bulking equipment inner chamber of material preparation and feeding screw, owing to the maximum operation (service) temperature of politef is 260 DEG C, at cabo
In microwave expansion continuous flow procedure, bigger microwave power and the inevitable accumulated temperature effect of microwave bulking device interior are often made
Forming apparatus cavity temperature is more than 260 DEG C, and microwave bulking equipment inner chamber and feeding screw component there will be thermal deformation phenomenon and with holding
The increase thermal deformation phenomenon loading with lotus can be accelerated, and microwave bulking equipment cavity collapse phenomenon even occurs time serious, affects safety
Produce.
Currently, in cabo microwave expansion production process, due to wave transparent, high temperature resistant and uniform stirring effect can be realized
The technical deficiency of material transfer equipment, causes Microwave expansion tobacco stem production capacity the highest, in addition the inhomogeneities of cabo moisture content,
Cause cabo microwave expansion uniformity poor;Meanwhile, single microwave expansion processes the shrivelled gas of expanded cabo often leading to obtain
Breath is relatively big, affects expansion stem suction quality.
