Filed:

Dec 12, 1977

Appl. No.:

5/859276

Inventors:

Douglas R. Hanson - Anoka MN

International Classification:

F26B 504

US Classification:

34 15

Abstract:

A dryer for automated washing and drying of mesh or perforated bottom trays such as those used for bakery goods, which includes a source of air under relatively low pressure and has a means to direct air at a relatively high velocity through the mesh or open bottom tray as it is carried on a perforated or open conveyor, and vacuum means connected to the suction side of the same fan to collect and receive moisture laden air and water droplets that pass through the tray and the conveyor. The fan includes a water-air separator on the inlet side so that the inlet air carrying the water is processed to remove water droplets and the like.

Appl. No.:

6/833087

Inventors:

Douglas R. Hanson - Coon Rapids MN

International Classification:

A21C 900

US Classification:

15306B

Abstract:

A vacuum hood for removing flour, dust, and other small particles from bakery products (dough pieces), including baffling which provides desired airflow paths adjacent leading and trailing edges of the hood. The hood overlies bakery products as the products are carried in pans on a conveyor belt moving in a path prior to baking. The hood has conduits for directing jets of air under pressure through orifices against the bakery products tending to lift the products at the same time that a vacuum is drawing particles of material inwardly under the edges of the hood to insure that excess flour, and other light particulate materials are drawn up into the hood efficiently without creating regions where the flour and particles may fall back onto the pans that are holding the bakery products. The air jets from above tends to circulate around the pockets in the bakery pans for the product causing currents that tend to lift the bakery products, so that crumbs, baking residues, and flour and any other dust particles are removed.

Appl. No.:

8/096710

Inventors:

Douglas R. Hanson - Anoka MN

Assignee:

Bake Star, Inc. - Anoka MN

International Classification:

A47L 1539
A46B 1302

US Classification:

15246

Abstract:

An apparatus dislodges material from a rotating brush having a brush axis and elongated bristles extending outwardly therefrom. The apparatus includes an obstruction device for temporarily obstructing free rotation of the bristles about the brush axis such that the bristles are placed in spring tension as the brush rotates. The obstruction device releases the bristles when sufficient spring tension exists therein.

Appl. No.:

6/306215

Inventors:

Douglas R. Hanson - Anoka MN

International Classification:

A47L 1539
A46B 1302

US Classification:

15 56

Abstract:

A brush assembly is utilized for cleaning pans in which loaves of bread are baked after the pans have been emptied of the bread. The brush assembly is mounted above a conveyor carrying the pans, and includes long bristle brushes rotating about axes oblique with respect to the direction of travel of the pans, and generally parallel to the plane of movement of the pans. The brush assemblies are oscillated up and down as they are rotated so that the brush tips tend to be repeatedly jabbed longitudinally into the corners of the pans to loosen seed, crumbs and other materials left in the pans.

Appl. No.:

5/601352

Inventors:

Douglas R. Hanson - Anoka MN

International Classification:

B65G 4722

US Classification:

198432

Abstract:

In a dough panning device, the dough piece orienter and intermediate guide sheet are mounted to permit longitudinal sliding movement along guide bars so that when the delivery end of the conveyor belt is moved to tension the belt these apparatus will maintain a proper relationship thereto. Also provided are adjustable side guides for the baking pans which may be individually adjusted laterally by means of parallel mounting links which are maintained in adjusted positions by friction clutches.

Appl. No.:

5/817435

Inventors:

Douglas R. Hanson - Anoka MN

International Classification:

A47L 1538
B08B 908

US Classification:

15304

Abstract:

A pan cleaning apparatus for use with bun and roll pans in bakeries which will use a combined air blast and vacuum action to loosen seeds, crumbs or the like as well as other foreign material which may be lodged in a bun pan after use. The device may include brushes arranged to brush all of the corners and recesses of the pan adequately for loosening material with the air blast-vacuum hood which removes debris from the pan used as a final cleaning stage.
