Definitions

  • the present invention relates to a machine for emulsifying a food product, to an ejector knife for the machine and to a method for emulsifying a food product.
  • Emulsifying machines are indispensable for reducing and breaking down food ingredients into a finely uniform product. They are typically used for making sauces, purees or sausage mince in industrial scale.
  • Emulsifiers are often very large machines configured for a throughput of several tons of food per hour. In addition to quality of the emulsified food product, noise and safety are important design parameters.
  • the food product is moved across an emulsifier stack by a pressure difference and/or by gravity.
  • the food is entered into a hopper above the machine. From the hopper, the food enters into an upstream section of the emulsifying part. From the upstream section, it moves by gravity and/or by a pressure difference to a downstream section on an opposite side of the emulsifier stack.
  • Variations in the pressure and/or in the structure of the food products may lead to uneven and loud operation and it may, eventually, reduce the quality of the emulsified food product.
  • the disclosure provides a machine comprising a pressure regulating structure configured to control the pressure difference between the upstream section and the downstream section.
  • the pressure difference can be controlled, a more stable pressure difference can be obtained leading to a more uniform and potentially better quality of the emulsified product. Additionally, the flow speed can be controlled by controlling the pressure difference and this inter alia allows control of the temperature of the food product. Accordingly, the ability to control the pressure difference improves the process in several different ways.
  • the pressure regulating structure may comprise a valve configured to control a fluid flow into or out of the conduit.
  • the valve could be a traditional flow control valve, e.g. a ball-valve etc.
  • the valve could be located in the downstream section, e.g. just below the emulsifier stack. This is advantageous since the pressure is low at this location and the pressure difference can therefore be controlled by letting air into the downstream section. This can be done particularly efficiently and simple by a valve arranged to open a passage between ambient space and the downstream section, i.e. simply letting ambient air into the conduit.
  • fluid flow may be provided between the conduit and a pressure source having a reference pressure which is higher or lower than the pressure in the conduit at the location of the valve.
  • the valve could be located anywhere in the conduit, e.g. in the upstream section, in the downstream section or therebetween.
  • the pressure source could be a pressurised bottle, e.g. with nitrogen or it could be a compressor or a suction pump etc.
  • the valve could be electrically controlled, e.g. by a computer. This allows the pressure difference to be controlled based on sensor signals from one or more pressure sensors in the conduit.
  • a controller may communicate with such a pressure sensor and with the electrically controlled valve, and it may control the valve based on the electrical pressure signal.
  • the outlet may be constantly open. This allows a more robust outlet without the risk of obstructing the flow by a closure mechanism which may have become stuck by emulsified food product sticking to the closure mechanism.
  • the constantly open outlet is enabled by the control of the pressure difference which thereby further simplifies the construction and makes the machine more robust and potentially reduces downtime due to a malfunction in a closure for the outlet.
  • the emulsifier stack may comprise at least one hole plate and at least one knife plate arranged towards each other, particularly arranged with a gap between each plate.
  • the food product is allowed to move from the upstream section to the downstream section by penetration of holes in each hole plate and in each knife plate. Since the knife plates rotate relative to the hole plates, the food is emulsified during the passing across the emulsifier stack.
  • An ejector knife may be arranged in the downstream section for ejecting the food product towards the outlet.
  • the ejector knife may generally have the shape of a propel, and it may be driven by the shaft via a connection between the shaft and a hub of the ejector knife.
  • the ejector knife may comprise ejector arms extending from the hub, and the ejector arms may have a shape such that each ejector arm extends radially outwards and defines a backwards projection extending tangentially backwards relative to a rotation direction of the shaft.
  • the backwards projection may particularly be at the tip of the ejector arms, i.e. furthest away from the hub.
  • Each ejector arm may define a radial section and a tangential section.
  • the radial section is located between the hub and the tangential section, i.e. the tangential section is furthest away from the hub.
  • a ratio L R /L T is a ratio between a radial length L R relative to a tangential dimension L T . This ratio is larger for the radial section than for the tangential section.
  • Each ejector arm may have a leading edge and a trailing edge. These edges are defined by the direction of rotation such that the leading edge is ahead of the trailing edge. With this definition, the ejector arms may be shaped such that a thickness in the axial direction is smaller at the trailing edge than at the leading edge.
  • the ejector knife may operate more silently and more efficiently if it has a surface with a roughness R a below 3,5, and even better below 2,5 or 1,5. This may be particularly important on the leading edges and/or near the leading edges.
  • the backwards projection may be radially displaced from the hub to define a gap, i.e. a void space along a radial tangent from the centre of the hub to the backwards projection.
  • the motor may be configured to rotate the shaft at constant speed.
  • the speed can be amended, but once it is specified by the operator, the motor will maintain a constant speed until the speed is amended again.
  • the pressure regulating structure may provide sufficient pressure change to initiate change a flow speed of the food product as a result of the change of the pressure difference between the upstream and downstream pressures. This allows flow control even at constant speed of the motor.
  • the ejector knife may be to create the pressure difference or at least a part of the pressure difference as a result of the rotation of the shaft. Another part of the pressure difference may be caused by the layout of the emulsifier stack.
  • the emulsifier stack may e.g. comprise a propeller arranged right after the upstream section, i.e. at an upstream part of the emulsifier stack.
  • This propeller may propel the food product into the emulsifier stack.
  • the propeller may be driven by the shaft, and it may comprise a propeller hub and propeller blades each extending from the hup towards a blade tip.
  • the blade tip may be located close to a wall of the conduit. Accordingly, a distance smaller than 10 mm between the conduit wall and the tip may be preferable.
  • a housing insert may be releasably received in, or fixedly joined with the housing.
  • the housing insert may extend about the propeller and form a part of the conduit.
  • the housing insert may form the conduit wall at the propeller, and it may thus ensure a short distance between the tip and wall of the conduit.
  • the housing insert may separate an inner chamber from an outer chamber such that the propeller, which is housed in the inner chamber is separated from an outer chamber being radially outside the housing insert.
  • this outer chamber is void, it may be useful for fluid communication between the conduit and an external pressure source such as the ambience since the void space and the housing insert may isolate the food product in the conduit from the valve and thereby reduce the risk of clogging.
  • the valve may provide fluid communication directly with the outer chamber.
  • An inner surface of the housing insert i.e. a surface facing the propeller may be rifled to improve the flow of the food product against the surface of the housing insert.
  • the shaft may enter the conduit via a shaft opening in the bottom of the housing.
  • the shaft may particularly enter directly into the downstream section.
  • the machine may comprise a sealing ring arranged between a shaft opening in the housing and the shaft.
  • the sealing ring serves to seal a gap between the shaft and the housing during rotation of the shaft relative to the housing and thus to ensure a stable pressure, particularly in the downstream section.
  • the sealing ring may comprise a sealing base arranged in contact with the housing, and at least one lip sealing portion extending radially from the base towards the shaft.
  • the lip sealing portion may further extend axially along an outer surface of the shaft in a direction away from the emulsifier stack. A low pressure in the downstream section as compared with ambient pressure will thereby push the lip sealing portion against the surface of the shaft and ensure a tight seal and a more stable low pressure in the downstream section. This may further increase the ability to control the pressure difference between the upstream section and the downstream section, and it may therefore further improve the emulsifying process and increase the ability to control flow speed based on the pressure difference.
  • the sealing ring is attached oppositely and comprises a sealing base arranged in contact with an outer surface of the shaft, and at least one lip sealing portion extending radially from the base towards the housing.
  • the lip sealing portion may extend axially along a surface of the housing in a direction away from the emulsifier stack.
  • the disclosure provides an ejector knife for an emulsifying machine, the ejector knife comprising a hub engageable by a shaft for rotation about an axially extending rotation axis, and ejector arms extending from the hub.
  • Each ejector arm may extend radially outwards and define a backwards projection extending tangentially backwards relative to a rotation direction of the shaft. This shape may reduce pressure fluctuations in the downstream section and reduce noise during operation.
  • Each ejector arm may define a radial section and a tangential section, the radial section located between the hub and the tangential section and a ratio L R /L T between a radial length L R relative to a tangential dimension L T , of the radial section is larger than the same ratio of the tangential section.
  • Each ejector arm may have a leading edge and a trailing edge, and wherein a thickness in the axial direction is smaller at the trailing edge than at the leading edge.
  • the backwards projection may be radially displaced from the hub to define a gap between the hub and the backwards projection.
  • the disclosure provides a method of emulsifying a food product in a machine comprising:
  • the method comprises conveying the food product from the upstream section to the downstream section by use of a pressure difference across the emulsifier, and controlling a flow speed of the food product through the emulsifier by amending the pressure difference.
  • the flow speed may be amended to cause a change in temperature of the food product, and the speed of the shaft may be amended to cause a change in temperature of the food product.
  • the disclosure provides a machine for emulsifying a food product comprising:
  • the specific shape and the backwards projection of the ejector knife provides a more stable pressure in the downstream section and thus potentially improves the process and improves the ability to control a pressure difference between the upstream section and the downstream section.
  • the machine may comprise any of the features mentioned relative to the machine according to the first aspect of the disclosure.
  • Each ejector arm may define a radial section and a tangential section, the radial section located between the hub and the tangential section and a ratio L R /L T between a radial length L R relative to a tangential dimension L T , of the radial section is larger than the same ratio of the tangential section.
  • Each ejector arm may have a leading edge and a trailing edge, and wherein a thickness in the axial direction is smaller at the trailing edge than at the leading edge.
  • the backwards projection may be radially displaced from the hub to define a gap between the hub and the backwards projection.
  • the specific details about the ejector knife improves the ability to provide a stable pressure in the downstream section.
  • Fig. 1 illustrates a machine for emulsifying food products in a perspective view
  • Fig. 2 illustrates the machine in a sideview including an electrical motor for driving the shaft of the machine.
  • the machine comprises a housing 2, e.g. made of stainless steel or a similar durable material.
  • a hopper 3 allows easy loading of food products into the machine, and the shaft 4 is connected to a motor 5 via a belt 6.
  • the emulsified food product leaves the machine via outlet 7.
  • Fig. 3 illustrates the emulsifier unit and Fig. 4 illustrates the emulsifier unit in a crosssectional view.
  • Fig. 5 illustrates the emulsifier unit in an exploded view.
  • the housing 2 is constituted by the upper housing part 31 and the lower housing part 32.
  • the housing defines a conduit illustrated by the dotted line 33 in Fig. 4 .
  • the conduit extends from an inlet 34 to the outlet 7.
  • the conduit 33 receives food products, e.g. lumps of meat (such as a mixture including minced meat) etc. from the hopper 3 ( Figs. 1 and 2 ), such that food product can enter the emulsifier in an efficient manner.
  • the machine is typically, however not necessarily, arranged in an upright orientation such that the gravity supports movement of the food product from the inlet to the outlet.
  • the food product are moved from the inlet to the outlet by a pressure difference between the upstream section and the downstream section.
  • the shaft 4 extends through the housing, and particularly through the lower housing part 32 into the conduit where it drives an emulsifier stack 35 and a ejector knife 36.
  • the shaft 4 rotates about a rotation axis indicated by the dotted line 37 and thereby define an axial direction along the rotation axis.
  • the arrow 38 indicates a radial direction which is perpendicular to the axial direction.
  • the arrow 39 indicates a tangential direction defining a tangent to the rotation direction and thus a tangent to the rotating parts of the machine.
  • the emulsifier stack 35 is driven by the shaft and arranged in the conduit to emulsify the food product when it moves from an upstream section of the conduit to a downstream section of the conduit.
  • upstream and downstream refers to the flow direction of the food product when it passes through the machine.
  • the emulsifier stack 35 comprises a plurality of hole plates 40-41 interleaved between knife plates 42-44. Both the hole plates and the knife plates are circular plates with holes. The hole plates are rotationally fixed by projections of the housing engaging the notch 45 of the hole plates. The knife plates are rotationally locked to the shaft via the hub structure 46 (only indicated on the top knife plate). Accordingly, the knife plates rotate relative to the hole plates, and the food product is emulsified as it moves from the upstream section to the downstream section by penetration of holes in each hole plate and in each knife plate during rotation of the knife plates relative to the hole plates.
  • the hole plates and the knife plates are arranged towards each, however, with a gap between them. Accordingly, the plates do not touch each other and wear of the surface of the plates can be reduced.
  • the emulsifier stack further comprises a propeller 47 urging the food product into the stack.
  • a housing insert 48 is inserted into the upper housing part 31 and encloses circumferentially the propeller 47.
  • the propeller 47 rotates in close vicinity to the wall of the housing insert which may improve the flow of food product.
  • the housing insert creates a void outer chamber between the upper housing part 31 and the housing insert 48.
  • the propeller comprises a propeller hub and propeller blades each extending from the hup towards a blade tip. The blade tip is located against a wall of the housing insert at a distance smaller than 10 mm such as smaller than 3 mm or 2 mm.
  • the pressure difference between the downstream section and the upstream section is inter alia caused by rotation of the knife plates relative to the hole plates and optionally also by the ejector knife 36 which propels the emulsified food product out of the outlet.
  • This propelling of the food product creates a low pressure in the downstream section as compared with the upstream section, and the pressure difference draws food into the emulsifier stack.
  • the machine further comprises a pressure regulating structure configured to control the pressure difference between the upstream section and the downstream section.
  • the pressure regulating structure comprises a valve 49 inserted into a port 50 and thereby controlling a fluid flow into or out of the conduit.
  • the valve could be located at any location in the conduit, however, the illustrated position at the downstream section may provide an advantage. At this section, the pressure is low, at the valve, when opening a passage e.g. to ambience, may reduce the low pressure. At this position, the pressure reduction will occur by letting ambient air into the conduit, and the risk of contaminating the ambience with the emulsified food product is low, or not existing since the fluid flow is inwards into the conduit.
  • Fig. 5 also illustrates that the outlet 7 is constantly open, i.e. there are no control valve arranged to open and close the outlet. This is possible since the flow can be controlled by the pressure regulating structure, e.g. in the form of the valve 49.
  • the lower housing part 32 forms a seal-housing closed by the cover 51.
  • the seal housing houses a seal which will be discussed in further details relative to Fig. 11 .
  • Fig. 6 illustrates an embodiment where the valve 49 is connected to a pressure source having a reference pressure.
  • the pressure source is illustrated by a pressure bottle 60, but it could be a suction pump, a compressor or any similar means for creating a flow out of, or into the conduit, i.e. a pressure which is higher or lower than the pressure in the conduit at the location of the valve.
  • Fig. 6 illustrates that the valve could be electrically controlled by a controller 61.
  • the controller may, additionally, communicate with a pressure sensor (not shown). In this way, the electrically controlled valve can be controlled based on a sensed pressure in the conduit.
  • the functions of the controller may be implemented using standard hardware circuits, using software programs and data in conjunction with a suitably programmed digital microprocessor or general-purpose computer, or a cloud computer, and/or using application specific integrated circuitry, and/or using one or more digital signal processors.
  • Software program instructions and data may be stored on a non-transitory, computer-readable storage medium, or in the cloud, and when the instructions are executed by a computer or other suitable processor control, the computer or processor performs the functions associated with those instructions.
  • the disclosure comprises software readable by computer means for carrying out the method and thereby providing the system for controlling the pressure difference between the upstream pressure and the downstream pressure.
