Abstract
Abstract For the purposes of saving flour and removing flour from the air for the safety of workers, large quantities of dusting flour used during the transfer of rolls from a standard dough dividing and rounding machine to a standard aging and panning machine is allowed to gravitate within an enclosure onto a screen covered flour chute which communicates at its lower end with a vacuum nozzle. The vacuum nozzle is connected by means of a hose with an overhead suction device on a flour holding tank having a flour sifting means at its lower end for delivering the dusting flour onto rolls while they are passing through a transfer chute between the two standard machines.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
218 words
In bakery product manufacturing apparatus of the type in which bakery products are transferred from a dough dividing and rounding machine to a dough ball aging and panning machine by means of an inclined transfer chute disposed between the two machines, and said apparatus further including a dusting flour holding tank having a lower end flour sifting means above said transfer chute, the improvement comprising a pair of enclosure side walls bridging the transfer zone between said two machines and being disposed on opposite sides of said transfer chute, said enclosure side walls having inclined lower edges below the transfer chute, a correspondingly inclined dusting flour chute immediately below the enclosure side walls and substantially abutting said inclined lower edges, said dusting flour chute extending somewhat above and below the upper and lower ends of said transfer chute, a sifting screen substantially covering the top of the dusting flour chute in spaced relation to the bottom wall thereof, the dusting flour chute being open at its lower end, a vacuum nozzle mounted immediately below the bottom wall of the dusting flour chute and having a lower end intake disposed in direct communication with the lower open end of the dusting flour chute, and excess dusting flour recycling means interconnecting said vacuum nozzle with said dusting flour holding tank.

In bakery product manufacturing apparatus of the type in which bakery products are transferred from a dough dividing and rounding machine to a dough ball aging and panning machine by means of an inclined transfer chute disposed between the two machines, and said apparatus further including a dusting flour holding tank having a lower end flour sifting means above said transfer chute, the improvement comprising a pair of enclosure side walls bridging the transfer zone between said two machines and being disposed on opposite sides of said transfer chute, said enclosure side walls having inclined lower edges below the transfer chute, a correspondingly inclined dusting flour chute immediately below the enclosure side walls and substantially abutting said inclined lower edges, said dusting flour chute extending somewhat above and below the upper and lower ends of said transfer chute, a sifting screen substantially covering the top of the dusting flour chute in spaced relation to the bottom wall thereof, the dusting flour chute being open at its lower end, a vacuum nozzle mounted immediately below the bottom wall of the dusting flour chute and having a lower end intake disposed in direct communication with the lower open end of the dusting flour chute, and excess dusting flour recycling means interconnecting said vacuum nozzle with said dusting flour holding tank.
Claim 3
Dependent Claim
65 words
In bakery product manufacturing apparatus as defined in claim 1, and said lower end intake of the vacuum nozzle comprising an arcuate wall extension on the lower end of the vacuum nozzle disposed in communicating relationship with the open lower end of said dusting flour chute and providing a reverse flow passage for dusting flour passing from the dusting flour chute to said vacuum nozzle.
Claim 4
Dependent Claim
56 words
In bakery product manufacturing apparatus as defined in claim 2, and an upper flange plate carried by the top of said arcuate wall extension and overlying the bottom wall of said dusting flour chute near the lower end portion thereof and defining with such bottom wall a dusting flour entrance slot for said reverse flow passage.
Claim 5
Dependent Claim
84 words
In bakery product manufacturing apparatus as defined in claim 3, and said sifting screen resting on said upper flange plate, a first holding bar for the lower end of said sifting screen secured to said arcuate wall extension, a second holding bar for the upper end of said sifting screen near the upper end of the dusting flour chute, and screw-threaded means on the dusting flour chute coupled with said second holding bar and operable to stretch said sifting screen to a taut condition.
Claim 6
Dependent Claim
48 words
In bakery product manufacturing apparatus as defined in claim 4, and spacer rod means on the dusting flour chute near the longitudinal center thereof and underlying the center region of the sifting screen to prevent sagging of the screen toward the bottom wall of the dusting flour chute.
Claim 7
Dependent Claim
36 words
In bakery product manufacturing apparatus as defined in claim 5, and a vibrator unit connected with the bottom wall of the dusting flour chute to assist the passage of flour downwardly thereon toward said vacuum nozzle.
