Definitions

  • This invention relates to apparatus for continously and automatically drying alimentary paste products, and more particularly to apparatus for automatically and continously drying long goods spaghetti as it feeds from a spaghetti press and then delivering th-at spaghetti in its dried state to a stripper for subsequent Weighing and packaging operations.
  • Spaghetti extruded from a spreader press normally has a moisture content-of about 31% by weight (wet basis). This spaghetti must be dried to a moisture content of about 11% before it is packaged or else it will develop mold in the package.
  • the novel transfer means devised to smoothly accomplish this transfer and change of flow pattern is an important aspect of our invention.
  • From the finishing drier the dried spaghetti moves on into an accumulator which provides a temporary storage area for the dried spaghetti.
  • a second transfer means similar to the first, carries the spaghetti on to the stripper wihch strips the spaghetti from the rods and cuts it into convenient lengths for packaging.
  • This transfer mechanism changes the multi-tiered ow back to single tier ow for passage to the stripper.
  • Another important aspect of our invention is the rack rod return system. After the dried spaghetti is removed from the return the empty rods to the spreader press for the next cycle through the drier.
  • Our apparatus is designed to run on a twenty-four hour day, five days a week continuous cycle.
  • the components are arranged to perform those operations which require the closest supervision, namely the stripping and packaging, during an eight hour normal work day period.
  • the extruding and drying operation can then continue through the night with little supervision., and the dried product is stored in the accumulator for stripping on the following workday.
  • the principal object of this invention therefore is to provide a means for continuously and uniformly drying production quantities of spaghetti inexpensively for eX- tended periods of time with a minimum amount of supervision.
  • Another object of our invention is to achieve uniformity of drying by using a plurality of tiered drying chains which carry groups of rack rods loaded with spaghetti through the drying line, each group moving through .the drier line in substantially the same vertical relationship until finally dried, thus assuring uniform drying for each member of each group.
  • Another object of our invention is to provide a continuous drier conveying mechanism and arrangement which carry the loaded rack rods in multi-tier advance through the sequential drying stages with a minimum number of transfer linkages to avoid jamming problems and thus assure smooth rack rod feed and flow.
  • Another object of this invention is to provide a drying apparatus which can be used in a fully automated spaghetti processing operation wherein semolina and water are mixed at one end and spaghetti ready to be packaged exists at the other end.
  • Another object of our invention is to provide a uniquely designed rack rod that is especially adapted for use in continuous drying equipment of the type herein described.
  • a further object of our invention is to provide in an automated spaghetti processing line a mechanism for automatically returning the empty rack rods from the stripper rack to the spreader press for continued passes through the processing line.

  • Rack rod return mechanism 17 automatically returns empty rods ⁇ from stripper 16 to press 10 -and stores them there for re-use through the line. Also essential to the operation of the complete drier line are rack rod transfer apparatus 18, which serve to connect each of the above stages and components to the other.
  • Finishing drier 13 first stage is maintained at about 115 and 85% relative humidity and transit time is approximately six hours.
  • the temperature is 100 F., relative humidity is 80%, and transit time is eight hours.
  • temperature is 100 F., relative humidity is 60%, and transit time is eight hours.
  • the spaghetti is in its fully dried condition 11% moisture by weight.
  • the dried spaghetti proceeds into accumulator 14 which stores the spaghetti temporarily until stripper 16 is put into operation.
  • the dried spaghetti is transferred from accumulator 14 to stripper 16 ⁇ by discharge elevator 15.
  • the necessity for Ithe storage space of accumulator 14 becomes readily apparent when the operating cycle of the complete spaghetti line is considered.
  • the extruder 10 is run at -full capacity twenty-four hours a day.
  • the extrusion, drying and accumul-ating operations run continuously day and night. This is economically justifiable because these operations need only minimal supervision.
  • the stripping and packaging operations on the other hand require close supervision and a large number of operators, and they 'are therefore performed during the normal eight hour Working day.
  • the stripping and packaging operations can be automated to the point where they can run in an eight hour period what the extruder and drier run in a twenty-four hour period. In order to synchronize the output rate of the extruder 10 and the driers 11 and 13 with ⁇ the output of the stripper 16 and the packaging equipment storage space must be provided, and this is the function of the accumulator 14.

  • preliminary drier 11 which also is of a conventional type as disclosed in Ambretti Patent 2,515,684.
  • spaghetti is extruded by press 10, cut to length by knife 10' and draped on rods 20 in the conventional manner.
  • the spaghetti is preliminarily dried on rods 20 by drier 11 and then proceeds to input elevator 12 (FIIG. 1).
  • rack rods 20 bearing the partially dried spaghetti are received from preliminary drier 11 on a pair of endless conveyor chains 21 driven by conventional motor means not shown.
  • Rods 20 approach input yelevator 12 in a single tier substantially horizontal ow.
  • Input elevator 12 receives rods 20 and transfers them to finishing drier 13 and in so doing changes the single tier flow to multi-tier flow. The means and manner by which this is accomplished will now be described.
  • Input elevator 12 comprises a pair of endless conveyor chains 22 driven by a pair of power sprockets 23 and tracked on three pairs of idler sprockets 24.
  • Sprockets 23 and 24 are mounted on shafts 23A and 24A respectively which are suitably journaled in bearings carried by framework 25.
  • Sprockets 23 and 24 are positioned to track chains 22 on a generally rectangular, clockwise path as viewed in FIGURE 3 bordering the interior of compartment panelling 26.
  • Power is supplied to power sprocket 23 by means of drive shaft 30 driven by a conventional motor 31 (FIG. 4). Power is transmitted through pulleys 32 and 33, timing belt 34, speed reducer 3S and sprocket 35A, and chain drive 36.
  • Chain 22 Operation of chain 22 is intermittent. Power is supplied to sprocket 23 only when the leading rack rod 20 from preliminary drier 11 is aligned transverse to chains 21 and 22 andadjacent to chain 22.
  • Controls utilized to insure this operation are a pair of normally open start switches 37, each having a trigger 38 adjacent each chain 21 and 22 that is actuated by each corresponding end of the leading rack rod 20 when fed to the correct transfer position along chains 21 and 22.
  • triggers 38 When both ends engage triggers 38, the electrical circuit supplying power to motor 31 for power shaft 30 is closed causing it to rotate sprocket 23 and thus advance chain 22 to move one of the rack rod support lugs (27A-D, 28A-D) into position so as to pick up and convey rack rod 20 upwardly.
  • Motor 31 continues to supply power to drive shaft 30 until its feed circuit is broken which occurs when the next advancing rack rod support lug engages trigger 40 of normally closed stop switch 41 which temporarily opens theholding circuit for motor 31 and thereby stops it. Motor 31 will be restarted and power supplied through sprocket 23 when the next following rack rod 20 reaches correct transfer position adjacent and transverse to chain 21 and 22 and triggers start switches 37 for another cycle. Switches 37 and 41 may be conveniently mounted on framework 25. Operation and placement of these switches for this purpose is described in greater detail in De Francisci Patent 2,724,482.
  • Lift off arm 42A isA supported from framework 25 by suitably journaled bearing block 43 and actuated about pivot pin 44 by linkage arm d5.
  • Linkage arm 45 is actuated by rocker 46 pivoted to suitably journaled bearing block 47 and moved by cam follower 48 driven by cam 50 on sprocket 51.
  • Sprocket 51 is mounted on shaft 51 which rotates freely in bearings in frame work 25 and is driven lby power sprocket 23 through intermediate idler sprocket 52 and chains 53 and 54,.
  • lift off arms 42.(A-D) are normally raised free and clear of descending rack rods 2@ carried by chain 21 (position shown in dash line).
  • cam follower 48 travels on the circular portion of cam 5d.
  • cam 50 is in a position shown such that cam follower 4S reaches the recessed cam surface causing lift off arms 4.2(A-D) to drop so as to intercept descending rack rods 29, carried by lugs 27(A-D) (position shown in solid line).
  • the loaded rack rods 2@ are carried through the finishing drier 13 by a series of conveyor chains of the same type as chains 55tA-D), all of which are driven by power drive shaft 39 through a corresponding series of transmissions.
  • a series of conveyor chains of the same type as chains 55tA-D are driven by power drive shaft 39 through a corresponding series of transmissions.
  • drive shaft 3i supplies power through belt 55 and speed reducer 57 mounted on framework 25.
  • drive shaft 30 also powers chain 22 in input elevator 12, thus causing rods 2d tol advance simultaneously from preliminary drier 11 to and through elevator 412 and through finishing drier 13.
  • Speed reducer sprocket 58 drives chain et? which drives sprocket 61.
  • 'Sprocket 61 is mounted on shaft 61A suitably journalled in pillow blocks 62 mounted on framework 25.
  • sprocket 63 Coaxially mounted on shaft 61A is sprocket 63 which engages chain 64A and 64B which drive sprocket 65A and 65B similarly mounted on pillow blocks 66A and 66B tothe framework 25.
  • Sprockets 65A and 65B drive sprockets 6](AD) by means of chains 68A and 68B and sprockets 69(A-D) mounted coaxial with sprockets 67(AD).

  • Conveying and driving mechanisms for each stage of finishing drier 13 and accumulator 14 are essentially the same as that described above. Gear ratios and chain pitches are selected to give the desired rack rod transit times specified above. Additionally, accumulator 14 is provided with an overrunning drive described hereinafter to accelerate transit of the dried product while stripper 16 is in use.
  • the next component in the line is the discharge elevator 15.

  • motor 80 Simultaneously with advancing of chain '79 around sprockets 84 and 55, motor 80 also drives sprocket 95 through sprocket 82 and chain 96. Attached to sprocket 95 about eccentric pin 97 is crank 9S which is pivoted about ⁇ bearing block 109 to framework 25 through suitable bearings. Supporting motor 80 and its appurtenant chains and sprockets is movable carriage 191.
  • Carriage 101 is .a rigid separable framework which supports thel framework of discharge elevator 15, motor and its appurtenant power transmission arrangement and is movably mounted on wheels 152 which are guided by rails 103. As sprocket rotates, the eccentric mounting of crank 97 causes carriage 101 to shift horozontally to the right (as seen in Fig. 6) away from the accumulator discharge sprockets 75(A-D) and chains WMA-D) so as to prevent their interference with the ascending spaghetti laden rack rods 2@ carried by chain 7 9.

  • Rack rod return chain 106 runs continuously while the drier is in operation to return empty rack rods 20 to press 10. We have found it desirable to provide a two speed drive for chain 106, high speed for day time operation when stripper 16 is in operation rapidly removing rods 20 from accumulator 14 and low speed when stripper 16 is off and only a low steady feed to press is required.
  • Chain 106 returns empty rods to the front end of the dried .adjacent press 10 where they are collected between the horizontal section of guide rail 112 positioned above the chain 106 at a distance which permits free slippage of chain 106 under the stored rods 20 beneath guide rail 112 without allowing rods 20 to bridge one another and jam up.
  • Rods are halted so yas to slip on chain 106 by a pair of spring retained pivoted stops 113, each one being pivotally mounted about frame work so as to engage the opposite ends of the first advancing empty rack rod 20. In normal operation a number of empty rack rods 20 are stored against stops 113.
  • Each stop 113 is provided with an arcuate recess 114 sized -to house the lead rack rod 20 snugly to prevent its riding up and jamming. Stop 113 is pivoted about pin 115 mounted to framework 25 and provided with suitable bearings to permit free movement. At the opposite end of each stop 113 is carn roller 116 which bears against cam 117 mounted coaxially on shaft 11S with sprocket 120. The force of rack rods 20 bearing against stop 113 holds cam roller 116 in contact with cam 117.
  • Sprocket 120 is driven intermittently by a conventional motor (not shown) through sprocket 121 and chain 122.
  • a group of equidistantly spaced rod support lugs 123A-E are mounted on and moved counterclockwise by chain 122 (as view in FIG. 2) so as to pick up empty rods 20 from where they bear against stops 113.

  • Spreader rack rod magazine 124 is similar to a'conventional rod delivery chute in that it extends downwardly and ends with a hook 127 which holds the leading rod 20 in position to be pickedup by chain 128 which supplies empty rods to press 10. Additionally, in our apparatus we have a spring retained rod metering arrangement to take the load of the stored rods ofi the leading rod 20 held by hook 127.
  • This arrangement comprises fixed lower chute 130, pivoted lower chute 131, fixed upper guide 132 and pivoted upper guide 133 terminating with partial hook 134. Chute 130 and guide 132 are fixed to framework 25, and chute 131 and guide 133 are pivoted about pins 131A and 133A respectively which are fixed to framework 25.
  • Tension in spring 135 is selected to provide a holding force between guide 133 and chute 130 just short of that required to hold back rods 20 when the lead rod 20 is lifted away from hook 127 by chain 128.
