The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
By Fig. 9, Figure 10 as seen, traditional edible film Compound Machining generally all adopts the metal tape curtain coating; The method of tunnel type temperature classification steam drying, its starch size 8 coat operate on the copper coin material-conveying belt 16 by extrusion coating paper 19 time, be subjected to scraper plate 5 to its of granting frictional force backward, and granted by extrusion coating paper 19 one frictional force forward, this two power forms a pair of shear stress that acts on slurry 8, make slurry 8 that the slippage of intermolecular layer phase take place, slurry 8 is by thick attenuation.
Yet this shear stress only acts on once in slurry 8 forming processes, and on the one hand this shear stress is not a constant force, in case slurry 8 leaves the position of scraper plate 5, shear stress just disappears, and 8 in slurry is subjected to the frictional force forward of being granted by extrusion coating paper 19.On the other hand because copper coin material-conveying belt 16 coefficients of heat conduction are big, under the vapor (steam) temperature condition that exists together, with the oven dry of being gone ahead of the rest by extrusion coating paper 19 contacted slurry 8 one sides, and slurry 8 another sides are still uncured, after shear stress disappeared, slurry 8 meeting deformation: thickness increased, upwards arch bending (seeing Fig. 5, Fig. 7).
The utility model has adopted the calendering complex method of constant voltage, lapse of temperature, and good thermograde can make glucose molecule ratio of briquetting, degree of preserving moisture obtain maximization; Good calenderability can make the glucose molecule chain maximize to arriving of the uniformity in length and breadth; The cleanliness of converted starch film increases, and with more fine and close by extrusion coating paper 19 adhesions, the mechanical performance after compound also will strengthen thereupon.
The utility model places a good forming temperature interval in order to ensure laminated film, designed one group of classification calender device of forming by N hot roll (seeing Fig. 1, Fig. 3), each hot roll 4 is hollow body, comprise cylinder, two cover plates, hollow shape axis 10, the outer surface of cylinder is not stained with coating for poly-tetrafluoro; The cover plate is connected with power chain; Hollow shape axis 10, one side concentric is cover one hollow input pipe 9 mutually, the opposite side concentric is cover one hollow delivery hose 11 mutually, input pipe 9 one side axis 10 and input pipe 9 radially respectively have a long groove milling, it is trapezoidal that groove milling is, delivery hose 11 1 side axis radially have a through hole, and delivery hose 11 inserts this hole can reach inner wall of rotary drum.
When power chain drives hot roll 4 runnings, input pipe 9 and delivery hose 11 with axis 10 mutual covers, be in relative static conditions, the relative angle between axis 10 and input pipe 9 long groove milling is radially regulated in rotation, thermal medium is under the effect of compression pump, be injected into inner wall of rotary drum one side of slurry 8 contact-making surfaces, regulate the effective angle and the temperature of all hot rolls 4, then form one from high to low (temperature province of A → H), the upper cold and lower heat non-uniform phenomenon (seeing Fig. 1, Fig. 3) that has not had general hot roll liquid heat medium to produce owing to gravity factor.
By Fig. 6, Fig. 8 as seen, slurry 8 enters slurry through compression pump and leaks bucket 6, driven by motor feeding spiro rod 12, regulate slurry and leak bucket switching baffle plate 7, slurry 8 is flow on the hot roll 4 by extrusion coating paper 19 surfaces by gravity, at scraper plate 5 with under by the effect of two frictional force of extrusion coating paper 19, formation acts on a pair of shear stress of slurry 8, make slurry 8 that the slippage of intermolecular layer phase take place, slurry 8 is by thick attenuation, evenly coat the poly-tetrafluoro of band and be not stained with on the coating drum, enter into another tangent with it hot roll 4 surfaces, 4 pairs of slurries 8 of two hot rolls and rolled by extrusion coating paper 19 by the surface of extrusion coating paper 19, this moment slurry 8 be subjected to hot roll 4 simultaneously and by extrusion coating paper 19 to its frictional force that applies, two contact top layers and heart portions are equally under the shear stress effect about in the of 8 for slurry, and intermolecular layer of phase slippage takes place slurry 8 once more, and slurry 8 is once more by thick attenuation, regulate the gap of 4 of every pair of hot rolls, the rest may be inferred, and through the repeatedly layer phase slippage between heart parton, slurry 8 thickness are progressively rolled attenuation.
Equally, slurry 8 is when progressively rolling, hot roll 4 also progressively gos deep into slurry 8 heart portions to its fuel factor, until slurry 8 complete film forming, because slurry 8 is two heating simultaneously up and down, not only film forming speed is accelerated, and two face the title moulding up and down, the glucose molecule chain is in length and breadth to evenly, and with the fashion superfluous water molecule in the heart portion slurry 8 of film forming not, the fuel factor during evaporation all occurs in slurry 8 zones (seeing Fig. 8 dash area), can not produce fracture phenomena to 8 one-tenth diaphragm areas of slurry, the cleanliness of slurry 8 form films increases, not only surface smoothness, transparency improves greatly, and the mechanical performance after compound also will strengthen thereupon.
Consider the influence that is intercepted by the 19 pairs of temperature of extrusion coating paper, can with heightened by hot roll 4 temperature of extrusion coating paper 19 phase-contact surfaces, and slightly turn down, to guarantee the harmony of being heated of 8 two in slurry with hot roll 4 temperature of slurry 8 phase-contact surfaces.
Because the exclusive temperature control mode of successively decreasing step by step of the utility model, thermal medium is back to second level hot roll 4 by connecting pipe in the cooled hot roll 4 of the first order, circulate successively until final stage hot roll 4, input to hot heat insulated tank and be circulated again in the first order hot roll 4 with after the heating source heating.Compared with the hot-working means of traditional open type, the utility model has not only been saved a large amount of energy consumptions, and workman's production environment, labour intensity are improved greatly.
In addition; original tunnel type steam drying method; in case run into the generation of disconnected film, adhesion, shutdown, not only each workman stay-warm case 15 of must slinging, and also percent defective is very high; the far-infrared sensor of the utility model configuration connects Control System of Microcomputer; can carry out online high slowdown monitoring to the multiple film streamline of whole piece, in case make mistakes, report to the police, shut down, show make mistakes reason and position automatically; save the manufacturing cost of enterprise in a large number, improved production efficiency.
Converted starch of a great variety, the series of deriving after the grafting is more huge, and the height of glucose, graft molecular weight will directly influence the molding parameter of its film.In addition, by the material of extrusion coating paper, thickness, heat conductivity, also all exist uncertain, the utility model can carry out gas, liquid, liquid gas mixture, oily substance thereupon and do selectively changing on the thermal medium of temperature control, on the number combinations of the stepwise gradient of N hot roll 4, all can do corresponding adjusting, stepwise gradient is long more, thermograde is then thin more, and filming performance is also just good more.Difference at each starch film product requires and characteristics, to parameters such as streamline line length, temperature, thermal medium, pressure, linear velocities, makes reasonable integration, and is equipped with computer control system, will help the efficient composite molding of starch film.
Through multistage hot roll 4 calenderings, combing and drying, composite membrane after the moulding, the also corresponding increase of fragility of composite membrane when mechanical performance strengthens, one air curtain, 17 device (see figure 1)s are set before the terminal recovery volume of streamline, pour into the gas of moisture content, its objective is in order to eliminate the stress in the composite membrane, strengthen the toughness of composite membrane.
