Abstract

Abstract A method of growing high quality bean sprouts on a mass production basis which consists briefly of placing a relatively large quantity of mung beans in a container, leveling and covering the quantity of beans with a substantially opaque receptacle cover for temporarily holding a quantity of water, the cover being formed with openings for the immediate distributed passage of water therethrough, initially covering the quantity of germinated beans with warm water and immediately draining the water from the container and thereafter periodically wetting said sprouts, draining off all water in the container, injecting warm air at a low pressure in a reverse direction to the drainage flow, and repeating the watering, drainage, and presurizing steps at intervals until the bean sprouts have matured. The apparatus consists briefly of a container having vertical side walls, bottom walls sloping at a slight angle to a central drain and a screen covering the drain area. A substantially opaque receptacle cover with perforations to permit the even distribution of water to the container is slideably mounted within the container to rise as the sprouts develop and fill the container. A pressure pump and an optional vacuum pump are connected to the container through the water drain.

Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 177 words
A method of growing germinated bean sprouts comprising the steps of: a. placing a quantity of germinated beans to a uniform depth in a container having substantially vertical side walls, an open top, a drain opening in the bottom wall and the bottom wall having a gently sloping floor in the direction of the drain; b. placing over said beans a substantially opaque relatively rigid cover having a plurality of openings adapted for admitting water and air therethrough and slideably mounted in said container to rise with the growth of said sprouts; c. periodically introducing a pre-selected amount of water onto said cover for distribution thereby onto said beans; d. draining the water immediately from said beans through said drain opening; and e. periodically flowing air through said growing bean sprouts at a selected pressure which will not disturb the orientation of said sprouts, in a direction opposite to the flow of water through said container, and after each introduction of water for a pre-selected duration until there is a substantial change of air within the container.
Claim 2
Independent Claim 177 words
A method of growing germinated bean sprouts comprising the steps of: a. placing a quantity of germinated beans to a uniform depth in a container having substantially vertical side walls, an open top, a drain opening in the bottom wall and the bottom wall having a gently sloping floor in the direction of the drain; b. placing over said beans a substantially opaque relatively rigid cover having a plurality of openings adapted for admitting water and air therethrough and slideably mounted in said container to rise with the growth of said sprouts; c. periodically introducing a pre-selected amount of water onto said cover for distribution thereby onto said beans; d. draining the water immediately from said beans through said drain opening; and e. periodically flowing air through said growing bean sprouts at a selected pressure which will not disturb the orientation of said sprouts, in a direction opposite to the flow of water through said container, and after each introduction of water for a pre-selected duration until there is a substantial change of air within the container.
Claim 3
Dependent Claim 26 words
A method of growing bean sprouts as described in claim 1 comprising: a. said pressured air has a pressure of less than 1 centimeter of water.
Claim 4
Dependent Claim 29 words
A method of growing bean sprouts as described in claim 1 including: a. injecting ozone into the air used to subject said beans to said low air pressure flow.
Claim 5
Dependent Claim 41 words
A method of growing bean sprouts as described in claim 1 wherein: a. said container is approximately 60 centimeters in height; and b. the bottom of said container is covered with beans to a depth of about 2 to 5 centimeters.
Claim 6
Dependent Claim 29 words
A method of growing bean sprouts as described in claim 1 wherein: a. the temperature of water introduced to said beans varies from about 15° C. to 30° C.
Claim 7
Dependent Claim 30 words
A method as described in claim 1 wherein: a. the cycle of watering, draining, and back pressuring is repeated at regular intervals approximately 4 to 10 times each 24-hour period.
Claim 8
Dependent Claim 48 words
A method as described in claim 1 comprising: a. applying a vacuum through the drain opening in said container of about 40 to 80 centimeters of water pressure for a duration of about 5 to 10 seconds after each watering step to drain excess water from said beans.
Claim 9
Dependent Claim 49 words
A method as described in claim 1 wherein: a. said back pressure has a duration of about 1 to 5 minutes and the pressure is at least sufficient to push upwardly through all of the bean sprouts in said container and is less than 10 centimeters of water pressure.
Claim 10
Independent Claim 106 words
An apparatus for growing bean sprouts comprising: a. at least one container having substantially vertical side walls, an open top, a drain opening in a bottom wall which gently slopes toward said drain opening: b. a container top substantially opaque and being formed with a plurality of openings for admitting water and air therethrough, said top being generally coextensive with the area of said container and mounted for vertical sliding movement therein; c. means for introducing water to the top of said container; and d. means for creating pressure attached to said drain for forcing air upwarldy through the beans and bean sprouts in said container.
Claim 11
Independent Claim 106 words
An apparatus for growing bean sprouts comprising: a. at least one container having substantially vertical side walls, an open top, a drain opening in a bottom wall which gently slopes toward said drain opening: b. a container top substantially opaque and being formed with a plurality of openings for admitting water and air therethrough, said top being generally coextensive with the area of said container and mounted for vertical sliding movement therein; c. means for introducing water to the top of said container; and d. means for creating pressure attached to said drain for forcing air upwarldy through the beans and bean sprouts in said container.
