CROSS REFERENCE TO RELATED APPLICATIONS
[01] This application claims priority to U.S. Provisional Application No. 61/782,615, filed
on March 14, 2013, entitled "Intermittent Dosing," and is related to U.S. Provisional
Application No. 61/695,135, filed on August 30, 2012, entitled "Intermittent Dosing
of Liquids," and International Application No. PCT/US 13/57015, filed on August 28,
2013, entitled "Intermittent Dosing of Liquids," the entire disclosures of which are
hereby incorporated by reference in their entirety and for all purposes.
FIELD OF THE INVENTION
[02] This disclosure relates generally to a method and beverage dispensing system for the
dispensing of beverages, e.g., for cafeterias, restaurants (including fast food
restaurants), theatres, convenience stores, gas stations, and other entertainment and/or
food service venues.
BACKGROUND
[03] Various beverage dispensers, such as those at cafeterias, restaurants, theatres and
other entertainment and/or food service venues, typically have either a "drop in"
dispenser apparatus or a counter top type dispenser apparatus. In a drop in dispenser
apparatus, the dispenser apparatus is self-contained and may be dropped into an
aperture of a counter top. In a counter top type dispenser apparatus, the dispenser
apparatus is placed on a counter top. In conventional beverage dispensers, a
dispensing head is coupled to a particular drink syrup supply source via a single pipe
dedicated to supply the particular drink syrup to that dispensing head, wherein the
particular drink syrup supply source is typically located near the counter top, i.e.,
directly under the counter top, or directly over the counter top.
[04] A user will typically place a cup under the signage of the selected beverage and either
press a button or press the cup against a dispensing lever to activate the dispenser so
that the selected beverage is delivered from the dispensing head corresponding to the
selected beverage and into the cup until pressure is withdrawn from the button or
lever.
[05] Conventional beverage dispensers are typically limited to dispensing a limited number
of drinks. For example, drinks typically available at a conventional beverage
dispenser are a regular cola beverage, a diet cola beverage, perhaps one or several
non-cola carbonated beverages, such as a lemon-lime flavored carbonated beverage or
some other fruit-flavored drink (e.g., orange flavored carbonated beverage, and/or
root beer), and perhaps one more non-carbonated beverage(s), such as a tea and/or a
lemonade.
[06] Conventional dispensers typically dose simultaneously components of a mixture or
beverage, and the final product is obtained as a result of mixing of two or more
continuous flows of the product components. This conventional approach may work
well when only low concentrated components are used. If, however, one or more of
the components is highly concentrated, the flow rate of such highly concentrated
component(s) required for continuous mixing becomes very small. In order to create
and maintain such very small and stable flows, very precise and thus more expensive
dosing and dispensing equipment is required. Less expensive but less precise
equipment may be able to dose highly concentrated components with required level of
accuracy, but the resulting flow rate of the created flow of such components may be
unacceptably high and thus inappropriate for continuous mixing of flows.
[07] What is needed is a beverage dispensing system that does not have the limitations and
disadvantages of conventional beverage dispensers and methods.
SUMMARY

[30] FIG. 1 shows a system 1200 comprising a dosing control unit 1203. Dosing control
unit 1203 may comprise a controller 1202. Controller 1202 may be operatively
connected to a dosing device 1204. In accordance with an aspect of the disclosure,
controller 1202 may be configured to control dosing by dosing device 1204 so that the
dosing is intermittent dosing of a highly concentrated micro component 1206. As
shown in FIG. 1, two-way communication may be provided between controller 1202
and dosing device 1204 so that controller 1202 can deliver instructions to dosing
device 1204, and dosing device 1204 can deliver to the controller 1202 information
relating to the operation of dosing device 1204. Dosing device 1204 may be a dosing
device configured to dose one or more liquid components of a plurality of sources.
Each source may comprise a cartridge 1201. Each source may comprise a component
of a free flowing product. The free flowing product may comprise a food product.
The food product may comprise a beverage. Thus, each source of the plurality of
sources may comprise a highly concentrated micro component. Each highly
concentrated micro component may comprise, for example, one or more of beverage
ingredients.
[31] As shown in FIG 1, controller 1202 may be configured to control operation of micro
component pump 1208 and micro component valve 1210 via two way communication
between controller 1202 and micro component pump 1208 and micro component
valve 1210, respectively.
[32] Controller 1202 may be configured to control intermittent dosing of one or more other
micro components 1216, in a similar manner as for micro component 1206, e.g.,
controlling via two way communication (not shown) between controller 1202 and a
micro dosing device, a micro component pump, and/or a micro component valve
corresponding to each micro component 1216.
[33] Controller 1202 may be configured to control dosing of a sweetener 1218, in a similar
manner as for micro component 1206, e.g., controlling via two way communication
(not shown) between controller 1202 and a dosing device, a pump, and/or a
component valve corresponding to the sweetener 1218. In accordance with the
present disclosure, dosing of the sweetener may be intermittent or not intermittent. In
accordance with the present disclosure, a dosing device, a pump, and/or a component
valve corresponding to the sweetener 1218 may be a micro dosing device, a micro
component pump, and/or a micro component valve corresponding to sweetener 1218,
respectively.
[34] Controller 1202 may be configured to control operation of water pump 1212 and main
diluent valve 1214 via two way communication between controller 1202 and water
pump 1212 and main diluent valve 1214, respectively.
[35] In accordance with an aspect of the disclosure, a highly concentrated liquid micro
component 1206 is intermittently dosed and dispensed, and the intermittent dose of
micro component 1206 may be mixed with the flow of other components 1216, and or
mixed with a low concentrated and/or macro component(s). By using intermittent
dosing and dispensing of the highly concentrated liquid micro component 1206, less
precise and thus less expensive equipment is required than if the highly concentrated
liquid micro component 1206 was continuously dosed and dispensed so as to mix
with a continuous flow of low concentrated liquid macro component(s). For example,
highly concentrated liquid micro component 1206 may mix with a flow of low
concentrated liquid macro components prior to or at dispensing nozzle 1220. In an
aspect of the present disclosure, highly concentrated liquid micro component 1206
may mix with a flow of low concentrated liquid macro components in cup 1222
placed underneath dispensing nozzle 1220. The mixing of highly concentrated liquid
micro component 1206 and other beverage components results in a finished beverage
1224.
[36] FIG. 1A shows another system 1200A for a dispensing system in accordance with
various aspect of the disclosure that may be used in place of or with various
components shown in FIG. 1. The control unit 1203 (of FIG. 1) may comprise a
controller 1202 that may be operative ly connected to a micro component valve
1204A. In accordance with an aspect of the disclosure, controller 1202 may be
configured to control dosing by micro component valve 1204A so that the dosing is
intermittent dosing of a highly concentrated micro component 1206.
[37] Two-way communication may be provided between controller 1202 and micro
component valve 1204A so that controller 1202 can deliver instructions to micro
component valve 1204A, and micro component valve 1204A can deliver to the
controller 1202 information relating to the operation of micro component valve
1204A. Micro component valve 1204A may be configured to dose one or more liquid
components of a plurality of sources. Each source may comprise a cartridge 1201.
Each source may comprise a component of a free flowing product. The free flowing
product may comprise a food product. The food product may comprise a beverage.
Thus, each source of the plurality of sources may comprise a highly concentrated
micro component. Each highly concentrated micro component may comprise, for
example, one or more of beverage ingredients.
[38] Controller 1202 may be configured to control operation of micro component pump
1208A via two way communication between controller 1202 and micro component
pump 1208A. Controller 1202 may be configured to control intermittent dosing of
one or more other micro components 1216, in a similar manner as for micro
component 1206, e.g., controlling via two way communication (not shown) between
controller 1202 and a micro dosing device, a micro component pump, and/or a micro
component valve corresponding to each micro component 1216.
[39] Controller 1202 may also be configured to control operation of air vent 1103,
accumulator 1105, and regulator 1107. The controller may control set points of each
device to ensure proper dosing of the highly concentrated micro components. In
another embodiment, air vent 1103, accumulator 1105, and regulator 1107 may be
factory set and adjusted at various maintenance cycles.
[40] In an embodiment, controller 1202 may retrieve from memory instructions regarding
the dosing characteristics for a particular micro component. The dosing
characteristics may include a pressure setting and dispensing time for each micro
component. Based on the received dosing characteristics, controller 1202 may control
micro component pump 1208A and micro component value 1204A based on those
characteristics. For instance, in an embodiment, micro component pump 1208A may
pump highly concentrated micro component 1206 from its cartridge 1201 via check
valve 1101. An air vent 1103 may remove any air trapped in the line between the
micro component pump 1208A discharge through to the micro component valve
1204A.
[41] In an aspect of the disclosure, accumulator 1105 may store or keep the highly
concentrated micro component 1206 under a set pressure until instructed by the
controller 1202 to open micro component valve 1204A. The pressure may be
regulated by a regulator 1107 based upon the particular micro component
characteristics and/or other external factors such as ambient temperature or pressure.
In an embodiment, controller 1202 based on the dosing characteristics, including the
pressure setting for each of micro components stored in the accumulator, opens the
micro component value 1204A for a corresponding amount of time to dose a
predetermined amount of micro component. For example, a particular micro
component may have a pressure regular setting of approximately twenty-five psi and
enable its associated micro component value to stay open for approximately eight
milliseconds. In another embodiment, a micro component that that includes a more
viscous product such as a juice may require a higher pressure and/or a longer micro
component value opening time to obtain proper dosing.
[42] Controller 1202 may be configured to control dosing of a sweetener 1218, in a similar
manner as for micro component 1206, e.g., controlling via two way communication
(not shown) between controller 1202 and a micro component valve, a pump, and/or a
component valve corresponding to the sweetener 1218. In accordance with the
present disclosure, dosing of the sweetener may be intermittent or not intermittent. In
accordance with the present disclosure, the sweetener 1218 may be located under a
counter or remotely such as in a back room. The sweetener 1218 may be connected
via a connector to a dual acting diagram pump which extracts the sweetener and
pumps it to the front room having the dispenser. An air vent may be located near the
pump discharge to remove any trapped air. A regulator may be used to regulate the
pressure of the sweetener stream. In an embodiment, the sweetener stream may be
dosed by a micro component valve. In another embodiment, the sweetener stream
may be split into multiple sweetener streams and dosed by multiple micro component
valves to provide a more uniform flow pattern with improved final beverage
characteristics.
[43] In another aspect of the disclosure, controller 1202 may also be configured to control
dosing of a non-nutritive sweetener. The non-nutritive sweetener may be dosed
similar to the sweetener stream 1218, discussed above. The non-nutritive sweetener
may also be split into multiple streams to provide a more uniform flow pattern with
improved final beverage characteristics.
[44] Controller 1202 may be configured to control operation of water pump 1212 and main
diluent valve 1214 via two way communication between controller 1202 and water
pump 1212 and main diluent valve 1214, respectively. In an embodiment, two
independent diluent streams may be utilized such as a carbonated diluent stream and a
non-carbonated diluent stream. Each diluent stream may have its own dilute pump
1212A and 1212B. In an embodiment, the diluent streams may be treated in the back
room with a water treatment package to remove all of the chlorine. Also, the total
alkalinity may also be reduced. The diluent streams may be pumped to the front room
having the dispenser through a recirculating system. In an embodiment, both the
carbonated diluent stream and the non-carbonated diluent stream are recirculated.
The recirculated diluent streams provide increased beverage selections as beverages
having different compositions of carbonated and non-carbonated diluents may be
dosed.
[45] In an alternative embodiment, the dispensing system may include a low volumetric
dosing device. A low volumetric dispensing system may include a pump, an
accumulator, an air vent, and the low volumetric dosing device. The low volumetric
dosing device may include a fillable chamber to hold and dispense precise amounts of
the micro component based on the beverage selection.
[46] FIG. 2 illustrates dispensing of a portion of beverage in accordance with an
embodiment of the present disclosure. As shown in FIG. 2, a highly concentrated
micro component(s) 1308 is intermittently dispensed from time 1310 to time 1312,
from time 1314 to time 1316, from time 1318 to time 1320, from time 1322 to time
1324, from time 1326 to time 1328, and from time 1330 to time 1332. As shown in
FIG. 2, a macro component 1304 is continuously dispensed from time 1302 to time
1306. As shown in FIG. 2, in an aspect of the disclosure, time 1302 may be the same
as time 1310.
[47] The length and frequency of the intermittent dosing times of highly concentrated
micro component 1308 may be selected so that the total amount of micro component
1308 will meet the desirable composition of the dispensed mixture, e.g., the dispensed
mixture 1220.
[48] FIG. 3 illustrates an optional approach, wherein dispensing of a highly concentrated
micro component 1400 is dispensed from time 1410 to time 1412. FIG. 3 illustrates
dispensing of a macro component 1404 from time 1402 to time 1406. Macro
component dispensing time 1402 to time 1406 may be longer than micro component
dispensing time 1410 to time 1412. Time 1402 may be the same as time 1410. The
start of micro component dispensing time 1410 and the start of macro component
dispensing time 1402 may begin when a customer or user activates dispensing, such
as by e.g., activating an actuator, e.g., pressing a start button or otherwise activates the
dispensing.
[49] FIG. 4 illustrates dispensing of a highly concentrated micro component 1400 is
performed sequentially from time 1410 to time 1412, from time 1414 to time 1416,
from time 1418 to time 1420, from time 1422 to time 1424, from time 1426 to time
1428, and from time 1430 to time 1432.
As shown in FIG. 4, macro component 1404 may be dispensed sequentially from time
1402 to time 1444, from time 1446 to time 1448, from time 1450 to time 1452, from
time 1454 to time 1456, from time 1458 to time 1460, and from time 1462 to time
1464.
[51] As shown in FIG. 4, in an aspect of the disclosure, time 1402 may be the same as time
1410, time 1446 may be the same as time 1414, time 1450 may be the same as time
1418, time 1454 may be the same as time 1422, time 1458 may be the same as time
1426, and time 1462 may be the same as time 1430.
[52] As shown in FIG. 4, in an aspect of the disclosure, time 1444 is prior to time 1446 and
time 1414, time 1448 is prior to time 1450 and 1418, time 1452 is prior to time 1454
and 1422, time 1456 is prior to time 1458 and 1426, and time 1460 is prior to time
1462 and time 1430.
[53] As illustrated in FIG. 4, macro component dispensing time 1402 to time 1444 may be
longer than micro component dispensing time 1410 to time 1412, macro component
dispensing time 1446 to time 1448 may be longer than micro component dispensing
time 1414 to time 1416, macro component dispensing time 1450 to time 1452 may be
longer than micro component dispensing time 1418 to time 1420, macro component
dispensing time 1454 to time 1456 may be longer than micro component dispensing
time 1422 to time 1424, macro component dispensing time 1458 to time 1460 may be
longer than micro component dispensing time 1426 to time 1428, and macro
component dispensing time 1462 to time 1464 may be longer than micro component
dispensing time 1430 to time 1432.
[54] The start of micro component dispensing time 1402 and the start of macro component
dispensing time 1406 may begin when a customer or user presses a start button or
otherwise activates the dispensing.
[55] The start of micro component dispensing time 1402 and the start of macro component
dispensing time 1406 may begin when a customer or user presses a start button or
otherwise activates the dispensing. The end of micro component dispensing time 1416
may occur when a customer or user releases a start button or otherwise activates the
end of dispensing of the micro component. As shown in FIG. 4, since macro
component dispensing time 1426 may be longer than micro component dispensing
time 1416, macro component dispensing time 1426 may not end at the same time as
micro component dispensing time 1416 ends.
[56] FIG. 5 illustrates a flow diagram of a method 1500 in accordance with various aspects
of the disclosure. In step 1501, a flow of a diluent is provided during a first period of
time. In step 1502, dosing of a highly concentrated micro component occurs during a
second period of time. The second period of time may be less than the first period of
time. The second period of time may overlap with a portion of the first period of
time. In step 1503, controlling the dosing of the highly concentrated micro
component occurs. In step 1504, mixing of the dosed highly concentrated micro
component and the flow of the diluent to form a mixture occurs. In step 1505,
dispensing of the mixture from a dispenser occurs.
[57] FIG. 6 illustrates an example of a dosing control unit 1203, as shown in FIG. 1.
Dosing control unit 1203 may comprise a controller 1202 as shown in FIG. 1.
Controller 1202 may comprise a processor. Dosing control unit 1203 may further
comprise at least one non-transitory memory 602, a display 604, and a communication
interface 608. Controller 1202 may execute computer-executable instructions present
in non-transitory memory 602 such that, for example, dosing control unit 1203 may
send and receive information via a network (not shown).
[58] Dosing control unit 1203 may further include or be in communication with a system
bus (not shown). A system bus may be any of several types of bus structures
including a memory bus or memory controller, a peripheral bus, and a local bus using
any of a variety of bus architectures. The structure of system non-transitory memory
is well known to those skilled in the art and may include a basic input/output system
(BIOS) stored in a read only memory (ROM) and one or more program modules such
as operating systems, application programs and program data stored in random access
memory (RAM). Dosing control unit 1203 may be configured to allow dosing control
unit 1203 to communicate other devices in system 1200, for example, microcomponent
pump 1208, micro dosing device 1204, micro-component valve 1210,
water pump 1212, and/or main diluent valve 1214. Dosing control unit 1203 may also
include a variety of interface units and drives (not shown) for reading and writing
