P/00/0 11 Regulation 3.2 AUSTRALIA Patents Act 1990 COMPLETE SPECIFICATION INNOVATION PATENT A FOOD GRADE EDIBLE OIL DISPENSING SYSTEM AND A MULTI FOOD GRADE EDIBLE OIL DISPENSING APPARATUS The following statement is a full description of this invention, including the best method of performing it known to us: 1 Field of the Invention The present invention relates to the bulk handling of edible oil. More specifically, it pertains to a food grade edible oil dispensing system and a multi food grade edible oil dispensing apparatus for dispensing of an edible oil to a cooking apparatus. 5 The invention has been developed primarily for use with the storage and dispensing edible oil in the restaurant, fast food or food manufacturing businesses and will be described hereinafter with reference to this application. However, it will be appreciated that the invention is not limited to this particular field of use. Background of the Invention 0 Large amounts of edible oil are used during the preparation of food in, for example, the restaurant business, especially in fast food restaurants. In some cases, large amounts of different types of edible oil may also be required. In the example of deep fat frying, a bath of hot oil is used for cooking the food. In these cases, the edible oil is usually used for only a predetermined amount of time and replaced with fresh edible oil periodically. 5 Given the large number of fast food restaurants and the quantity of edible oil they require, the supplying of edible oil to these facilities has become a focus of many businesses. Edible oil is typically delivered and stored within the restaurant until required. There have been arrangements by which the fresh edible oil is stored in portable drums, occupying significant amounts of valuable space at the premises. Such portable drums are usually bulky and 0 heavy, requiring restaurant personnel handling the drums to be strong enough to manually lift the drums to pour oil from the drums into cooking apparatuses. Incidents such as oil spillage and the handling of heavy drums raise occupational health and safety issues. Such drums are also usually disposable, resulting in wastage of material. Other arrangements for the storage and dispensing edible oil include situations where a 25 refillable fresh edible oil tank is located on the restaurant premises. Appropriate infrastructure such as piping and taps are required in such cases for refilling of the cooking apparatuses with fresh oil from the fresh edible oil tank. Alternatively, appropriate hosing may be connected to the fresh edible oil tank to dispense fresh edible oil from the fresh oil tank to the cooking apparatus. This alternative approach is rather cumbersome since it 30 requires the frequent connection and disconnection of the hose. Incidents such as oil dripping from the connection points of the hose could result in an oil spillage thereby raising occupational health and safety issues. Such tanks may also be overfilled during refilling, 2 which raises further safety issues such as those associated with pressurised or cracked and leaking tanks. Another arrangement which has been developed to reduce the amount of manual handling of the edible oil and amount of space required to store the fresh edible oil involves the use of 5 wheeled tanks which can fit underneath kitchen workbenches. Such tanks are usually fitted with a pump that pumps fresh oil from the tank to the cooking apparatus through a hose. Refilling of such tanks can be done by wheeling the tank to a remote tank or delivery vehicle from which the fresh edible oil can be transferred. While this system reduces the risk of oil spills when handling the edible oil, concerns have been raised about the cleanliness of the 10 non-food grade pump and corresponding food safety issues. The present invention seeks to provide a food grade edible oil dispensing system for dispensing of an edible oil to a cooking apparatus and a multi food grade edible oil dispensing apparatus comprising two or more food grade edible oil dispensing systems, such that one or more different edible oils can be readily dispensed to one or more cooking 15 apparatuses, which will overcome or substantially ameliorate at least some of the deficiencies of the prior art, or to at least provide an alternative. It is to be understood that, if any prior art information is referred to herein, such reference does not constitute an admission that the information forms part of the common general knowledge in the art, in Australia or any other country. 20 Summary of the Invention According to a first aspect of the present invention, there is provided a food grade edible oil dispensing system for dispensing an edible oil to a cooking apparatus, comprising: - an edible oil storage container; - a food grade pump; 25 - an edible oil conduit fluidly interconnecting the edible oil storage container and the food grade pump such that the edible oil can be selectively communicated by the food grade pump from the edible oil storage container to the cooking apparatus; and - a hose assembly operably connected to an outlet of the food grade pump and adapted to dispense the edible oil into the cooking apparatus. 30 Advantageously, the use of food grade materials in the food grade edible oil dispensing system reduces contamination of the edible oil. This is beneficial in circumstances where, for 3 example, the edible oil may take the form of a salad oil dressing which is not required to be subject to high temperatures after being dispensed and before being consumed by an individual. Advantageously, the edible oil contained in the edible oil storage container can only be 5 removed from the edible oil storage container by means of the food grade pump. This further reduces contamination of the edible oil since the edible oil stored in the edible oil storage container is not unnecessarily exposed to the atmosphere, for example, during manual dispensing such as pouring or ladling of the edible oil. Advantageously, the edible oil can be dispensed without the need for the edible oil storage 10 container to be lifted. This increases efficiency by preventing incidents such as spillage of oil and other occupational health and safety issues related to, for example, requirements for personnel to handle heavy drums when pouring the edible oil into the cooking apparatus. Advantageously, as the hose assembly is operably connected to the food grade edible oil dispensing system at all times, this precludes problems associated with the edible oil 15 dripping from the point of connection with the outlet of the food grade pump, as may be seen with other edible oil dispensing systems which require frequent connection and disconnection of the hose assembly from the edible oil dispensing system. Preferably, the food grade pump is a displacement pump or a velocity pump. Advantageously, the food grade pump is any pump suitable for pumping fluids that is 20 equipped with food grade pumping gear to prevent the edible oil from becoming contaminated during pumping. Preferably, the food grade pump complies with the regulations of the Australia New Zealand Food Standards Code (Standard 3.2.3), or the US 3A-Sanitary Standards, Inc. (3-ASSI) or the European Hygienic Engineering and Design Group (EHEDG) directives. For example, the food grade pump may be a food grade 25 displacement pump, such as a gear pump, a progressing cavity pump, a roots-type pump, a peristaltic pump or a reciprocating type pump, or may be a food grade velocity pump, such as a centrifugal pump, a radial flow pump, an axial flow pump, or a mixed flow pump. Advantageously, the food grade pump is manufactured using materials such as, for example, stainless steel, or a food grade polymer that comply with, for example, the 30 Australia New 4 systems, each as described in the first aspect of the present invention, such that two different edible oils can be readily dispensed to one or more cooking apparatuses. Advantageously, the multi food grade edible oil dispensing apparatus is able to dispense one or more different edible oils. This is beneficial in situations where, for example, a 5 restaurant business operates two cooking apparatuses - one for edible vegetable oil and one for another edible oil, or in situations where the restaurant business requires edible oil for a fryer and a lighter edible oil, for instances other than those required for cooking, such as an edible oil for salad dressings. Other aspects of the invention are also disclosed. 0 Brief Description of the Drawings Notwithstanding any other forms which may fall within the scope of the present invention, a preferred embodiment of the invention will now be described, by way of example only, with reference to the accompanying drawings in which: Fig. 1 is a front view schematic representation of a food grade edible oil dispensing 5 system for dispensing of an edible oil to a cooking apparatus in accordance with a preferred embodiment of the present invention; and Fig. 2 is a side view schematic representation of a multi food grade edible oil dispensing apparatus comprising two or more food grade edible oil dispensing systems, each as shown in Fig. 1, for dispensing two different edible oils to one or more cooking 0 apparatuses in accordance with another preferred embodiment of the present invention.

The food grade edible oil dispensing system for dispensing of an edible oil to a cooking 35 apparatus provides a number of advantages, including: 11 1. The use of food grade material in the food grade edible oil dispensing system reduces contamination of the edible oil. This is beneficial in circumstances where, for example, one of the one or more different edible oils takes the form of a salad oil dressing which is not required to be subject to high temperatures after being 5 dispensed and before being consumed by an individual, while another of the one or more edible oils takes the form of an edible oil for use in a cooking apparatus such as a deep fat fryer. 2. The edible oil contained in the edible oil storage container can only be removed from the edible oil storage container by means of the pump. This further reduces 0 contamination of the edible oil since the edible oil stored in the edible oil storage container is not unnecessarily exposed to the atmosphere, for example, during manual dispensing such as pouring or ladling of the edible oil. 3. The edible oil can be dispensed without the need for the edible oil storage container to be lifted. This increases efficiency by preventing incidents such as spillage of oil and 5 occupational health and safety issues related to, for example, requirements for personnel to handle heavy drums when pouring the edible oil into the cooking apparatus. 4. As the hose assembly is operably connected to an outlet of the food grade pump at all times, this precludes problems associated with the edible oil dripping from the point 0 of connection with the outlet of the food grade pump, as may be seen with other edible oil dispensing apparatuses which require frequent connection and disconnection of the hose assembly from the outlet of the food grade pump. 5. The food grade pump is any pump suitable for pumping fluids that is equipped with food grade pumping gear to prevent the edible oil from becoming contaminated during 25 pumping. Preferably, the food grade pump complies with the regulations of the Australia New Zealand Food Standards Code (Standard 3.2.3), or the US 3A-Sanitary Standards, Inc. (3-ASSI) or the European Hygienic Engineering and Design Group (EHEDG) directives.

In this second embodiment, the multi food grade edible oil dispensing apparatus 100 further comprises one or more control units 80A, 80B for controlling the corresponding food grade pumps 30A, 30B to selectively communicate the edible oil from the corresponding edible oil storage container 20A, 20B to the desired cooking apparatus. As described in the first 30 embodiment, the control units 80A, 80B in this second embodiment comprise an ON/OFF switch (not shown) to switch the corresponding food grade pump 30A, 30B ON and OFF, respectively. In other embodiments, the multi food grade edible oil dispensing apparatus 100 may comprise just a single control unit for controlling the one or more food grade pumps 30A, 30B to selectively communicate the edible oil from the corresponding edible oil storage 35 container 20A, 20B to the desired cooking apparatus. 14 As described in the first embodiment, the multi food grade edible oil dispensing apparatus 100 in this second embodiment further comprises three or more castor wheels 90 spatially distributed about the underside of the multi food grade edible oil dispensing apparatus 100 to provide the multi food grade edible oil dispensing apparatus 100 with both stability and 5 maneuverability. Preferably, the three or more castor wheels 90 are four or more castor wheels 90, the four or more castor wheels 90 being adapted to swivel 360 degrees around their respective vertical axes to enable the multi food grade edible oil dispensing apparatus 100 to be maneuvered across a surface upon which the multi food grade edible oil dispensing apparatus 100 rests in any direction within the horizontal plane. 0 In other embodiments, the multi food grade edible oil dispensing apparatus 100 may comprise just one food grade pump (not shown) to dispense the one or more different edible oils to, for example, one or more cooking apparatuses. In these other embodiments, the one food grade pump will be fluidly interconnected with the two edible oil storage containers 20A, 20B via the corresponding edible oil conduits 40A, 40B such that the one or more different 5 edible oils can be selectively communicated by the food grade pump from the edible oil storage containers 20A, 20B to the one or more cooking apparatuses. It will be appreciated that control of the flow of the one or more different edible oils from the corresponding edible storage containers 20A, 20B to the food grade pump may be implemented by the use of one or more valves (not shown) located in the edible oil conduit 40A, 40B, preferably, one way 0 valves, to prevent backflow of the one or more different edible oils from the food grade pump to the edible oil storage containers 20A, 20B. The multi food grade edible oil dispensing apparatus comprising two or more food grade edible oil dispensing systems, each as described in the first embodiment, such that different edible oils can be readily dispensed to one or more cooking apparatuses, provides a number 25 of advantages, including: 1. The multi food grade edible oil dispensing apparatus is able to dispense more than one type of edible oil. This is beneficial in circumstances where, for example, one of the one or more different edible oils takes the form of a salad oil dressing which is not required to be subject to high temperatures after being dispensed and before being 30 consumed by an individual, while another of the one or more edible oils takes the form of an edible oil for use in a cooking apparatus such as a deep fat fryer. 2. The use of food grade materials in the multi food grade edible oil dispensing apparatus and in the two or more food grade edible oil dispensing systems helps to reduce contamination of the one or more different edible oils stored in the 35 corresponding edible oil storage containers, and residual edible oil within the other 15 parts of the multi food grade edible oil dispensing apparatus, for example, edible oil conduits or the oil inlet conduits. 3. The edible oil contained in the edible oil storage containers can only be removed from the edible oil storage container by means of the food grade pump. This further 5 reduces contamination of the edible oil since the edible oil stored in the edible oil storage container is not unnecessarily exposed to the atmosphere, for example, during manual dispensing such as pouring or ladling of the one or more different edible oils. 4. The edible oil can be dispensed from the multi food grade edible oil dispensing apparatus without the need for the edible oil storage container to be lifted. This 0 increases efficiency by preventing incidents such as spillage of oil and occupational health and safety issues related to, for example, requirements for personnel to handle heavy drums when pouring the one or more different edible oils into the one or more cooking apparatuses. 5. As the hose assemblies are operably connected to the outlets of the corresponding 5 food grade pumps at all times, this precludes problems associated with the edible oil dripping from the point of connection with the outlets of the food grade pumps, as may be seen with other edible oil dispensing apparatuses which require frequent connection and disconnection of the hose assembly from the outlet of the food grade pump. 0 6. The food grade pump is any pump suitable for pumping fluids that is equipped with food grade pumping gear to prevent the one or more different edible oils from becoming contaminated during pumping. Preferably, the food grade pump complies with the regulations of the Australia New Zealand Food Standards Code (Standard 3.2.3), or the US 3A-Sanitary Standards, Inc. (3-ASSI) or the European Hygienic 25 Engineering and Design Group (EHEDG) directives. For example, the food grade pump may be a food grade displacement pump, such as a gear pump, a progressing cavity pump, a roots-type pump, a peristaltic pump or a reciprocating type pump, or may be a food grade velocity pump, such as a centrifugal pump, a radial flow pump, an axial flow pump, or a mixed flow pump. 30 7. The food grade pump is manufactured using materials such as, for example, stainless steel, or a food grade polymer that comply with, for example, the Australia New Zealand Food Standards Code (Standard 3.2.3) or the US Food and Drug Administration (FDA) regulations. 16 Interpretation Embodiments: Reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment 5 is included in at least one embodiment of the present invention.
