Definitions

  • the invention relates to a device, system and method for filling packages. More specifically, the present invention refers to a device, system and method for filling packages with food particles.
  • Liquids or substances having sufficiently low viscosity may be moved from a product tank to a package using standard pumps, in combination with standard volume measurements in order to control the amount of product being filled.
  • filling packages with food products in the form of food particles such as mushrooms, fruit, peas, or beans is normally made in two steps; first, the solid part of the food product (i.e. the actual mushrooms/fruits/etc.) are filled, before a second step of filling with brine or syrup or similar is performed.
  • the first part has proven to be very difficult to automate due to air pockets occupying an unknown amount of volume between individual food particles.
  • Solid food products are today often filled in volumetric pocket fillers, or manual filling is performed. Even for automatic filling processes, manual adjustment after filling is often necessary. Weight fillers can also be used for some types of solid food, giving better filling accuracy.
  • prior art systems may successfully fill packages with food particles. However, such machines cannot be used to accurately fill particles or pieces of food being sticky, irregularly shaped, to some extent fragile, spongy, or wet, without requiring manual adjustment after filling.
  • the food particles such as sliced mushrooms, are preferably transported on a conveyor into a filling tank.
  • the mushrooms shall contain as little water/moisture as possible when arriving to the filler.
  • the mushrooms are sucked into a piston pump controlled by a servomotor.
  • the stroke of the piston is about 40-80% longer, such as 50% longer than required for the desired filling volume.
  • a retract stroke to the nominal, or desired, filling volume is made before switching the piston pump connection from the tank to the filling nozzle. The retract stroke is compressing the product in the piston and pressing out the air between the food particles.
  • the profile and acceleration of the piston movement can be controlled in order to accurately control the filling process.
  • the piston pump may be emptied through a filling head that can cut food particles when closed if neccesary. Brine/liquid can be added into the package using another filler.
  • a device for filling at least one package with a first volume of solid food product comprises a pump operatively connected to a product tank containing the solid food product, at least one fill head operatively connected to the pump; a valve configured to selectively connect the pump to the product tank or to the fill head; and a control unit configured to control the valve to connect the pump to the product tank or to the fill head, and to control the pump to supply the first volume of solid food product to the fill head, wherein the control unit is further configured to control the pump to draw from the product tank a larger volume of solid food product than the first volume and to output the excess volume back towards the product tank.
  • the flow of product into and out of the pump is advantageous in that it makes the product more homogeneous, meaning that air is pushed out so that volumetric measurements become more standardised and the product is easier to handle.
  • the pump may be a reciprocating pump.
  • the reciprocating pump is advantageous in that it may easily be scaled depending on the first volume to be filled.
  • the pump may comprise a piston.
  • the piston is advantageous in that it increases the efficiency of the pump.
  • the device may comprise a motor for actuating the piston, such as a servo motor.
  • the motor is advantageous in that it allows for an increased speed of the piston and automatic control. This is especially true when using the control unit for controlling movement of the piston according to a software profile adapted for filling of specific food particles. In this way, potentially any solid product which has a corresponding software profile for the movement of the piston stored in the control unit or some external memory accessible by the control unit can be filled accurately into a container described earlier.
  • the software profile has the function of controlling the motion of the motor and thus the piston.
  • the excess volume of solid food product drawn from the product tank may be between 40-80% of the first volume to be filled.
  • This interval is advantageous in that it has been found by the inventors of this application to maximise the air pushed out while maintaining a high speed and efficiency.
  • the first volume to be filled may correspond to the volume of solid food product to be filled in only one package.
  • This volume is advantageous in that it allows for a simpler fill head and a simpler operative connection between the fill heads and the tank, resulting a simpler valve.
  • a system for filling at least one package with solid food product comprises a device according to the first aspect; a product tank containing the solid food product; at least one nozzle for pouring liquid into the at least one package; and a sealer for sealing the at least one package.
  • the system also comprises a heater for retorting the at least one package.
  • the system is advantageous in that it allows for an efficient cooperation of different components and produces a complete, retorted package of food ready to be consumed.
  • the system may comprise at least one liquid tank operatively connected to the at least one nozzle.
  • the liquid tank is advantageous in that it supplies the nozzle(s) in a simple and effective manner.
  • the system may comprise a conveyor belt for stocking the product tank with solid food product.
  • the conveyor belt is advantageous in that it may transport any solid food product in a fast manner.
  • a method for filling at least one package with solid food product comprises the steps of inputting into a pump a larger volume of solid food product than a first volume to be filled; returning the excess volume to a product tank; and supplying a fill head with the first volume of solid food product to be filled.
  • the flow of product into and out of the pump is advantageous in that it makes the product more homogeneous, meaning that air is pushed out so that volumetric measurements become more standardised and the product is easier to handle.
  • the method may comprise a step of stocking the product tank with solid food product.
  • the method may comprise a step of pouring liquid into the at least one package.
  • the method may comprise a step of sealing the at least one package.
  • the method may comprise a step of retorting the at least one package.
  • a device 1 for filling at least one package 10 with a first volume of solid food product, i.e. food particles, is illustrated.
  • the package 10 may be a cardboard box, a metal can, a plastic bottle or any other suitable packaging for food.
  • the package 10 is a retortable carton package designed for shelf-stable products traditionally filled in cans, glass jars or pouches - foods like vegetables, beans, tomatoes, pet food, soups and sauces.
  • Such carton package is commercially available and known as Tetra Recart ® .
  • the food particles may for example comprise mushrooms, pieces of fruit, or pieces of meat.
  • the solid food is heterogeneous and comprises chunks or particles of product with air pockets in between.
  • the solid food product may have some amount of liquid, for example between 0-20%, as long as the result is heterogeneous.
  • the solid food product is usually packaged in brine or another type of liquid, such as syrup, which is added to the at least one package 10 at a later stage as discussed below with reference to Fig. 3 .
  • the device 1 comprises a pump 4 operatively connected to a product tank 2 containing the solid food product, i.e. the solid part of the food product.
  • the pump 4 may be a reciprocating pump capable of drawing the solid food product from the product tank 2.
  • An advantage of a reciprocating pump is that it is very convenient to scale to variations in the filling volume of solid food product.
  • the scaling may e.g. be slave scaling.
  • one device 1 may be used for any number of filling volumes or package volumes. A skilled person will realise that the volume of the package 10 is not necessarily the same or even proportional to the filling volume.
  • the pump 4 preferably pumps at a speed and acceleration that is fast and efficient, but without causing any damage to the product.
  • the pump 4 is preferably operated automatically.
  • the purpose of the pump 4 is to draw solid food product from the product tank 2, and to later deliver the drawn solid food product to the package 10.
  • the fill volume i.e. the volume of solid food product being delivered to the package 10, is from now on denoted a first volume.
  • the pump 4 is made from a material suitable for containing solid food product periodically, such as a plastic, glass or metal and shaped e.g. substantially like a ball, box, cylinder, or tube.
  • the pump 4 is configured to accommodate a volume of solid food product being larger than the first volume, i.e. the volume to be filled in the package 10.
  • a volume of solid food product being larger than the first volume, i.e. the volume to be filled in the package 10.
  • the excess volume i.e. the difference between the drawn volume and the first volume, is then discharged from the pump 4 back towards the product tank 2.
  • the excess volume is consequently the difference between the input/drawn volume and the first volume to be filled. Outputting the excess volume back towards the product tank 2 does not necessarily mean that the product will reach the product tank 2.
  • the excess volume of the output product may instead e.g. be lodged in connection tubes.
  • This process compresses the solid food product to primarily discharge air from air pockets, to achieve a more homogeneous and compact solid food product. This means that by drawing extra volume and then outputting the extra volume, while the resulting volume of product is the same as without the extra steps, the resulting content actually fills the volume efficiently and may be used as a fair measurement.
  • the drawn volume is between 40-60% larger than the first volume to be filled. In another embodiment, the drawn volume is about 50% larger than the first volume to be filled.
  • the device 1 further comprises at least one fill head 8 operatively connected to the pump 4.
  • the fill head 8 is configured to dispense the solid food product supplied by the pump 4 into the at least one package 10.
  • the fill head 8 may e.g. be a nozzle, a funnel, or a pipe opening.
  • the fill head 8 preferably ensures that all solid food product supplied by the pump 4 is filled into the at least one package 10, either by using a feedback system such as sensors or simply by designing the fill head 8 such that spillage and loss is prevented.
  • the device 1 further comprises a valve 7 configured to selectively connect the pump 4 to the product tank 2 or to the fill head 8.
  • the valve 7 is preferably a passive component that does not impact the flow.
  • the valve 7 may for example be a branched pipe with a mechanical switch or a set of plugs that block different pathways depending on their positions.
  • the valve 7 may allow flow into or out of one or more than one pump 4.
  • the valve 7 preferably connects the pump 4 to the product tank 2 to allow for flow of solid food product between the product tank 2 and the pump 4 while the product is drawn into the pump 4 and while the excess volume of product is output back towards the product tank 2 as described previously. This process typically takes around half of a second for modern filling operations.
  • valve 7 allows for flow of product from the product tank 2 to the pump 4 and from the pump 4 to the product tank 2.
  • the valve 7 may be arranged to allow both directions of flow at the same time or to switch between allowing the two directions at different times.
  • valve 7 preferably switches to connect the pump 4 to the fill head 8 to allow for flow between the pump 4 and the fill head 8. This allows for the correct amount of solid food product contained in the pump 4 to be filled into the package 10 by the fill head 8. This process usually takes around half of a second for a modern filling operation.
  • the pump 4 comprises a piston 5 for controlling the flow of solid food product between the product tank 2 and the pump 4.
  • the piston 5 will initially drive the flow of solid food product into the pump 4, and by changing direction thus pushing the piston 5 forward, the product is output from the pump 4, either towards the product tank 2 or to the fill head 8.
  • the piston 5 is preferably moved at a speed and acceleration that is fast and efficient, but without damaging the product.
  • the device 1 may further comprise a motor 6 for driving the piston 5.
  • the motor 6 may be integrated into the piston 5 or arranged in conjunction with it and may be arranged to actuate one or more than one piston 5.
  • the motor 6 may be controlled by hand or automatically.
  • the motor 6 may e.g. be a step motor or an electrical motor and is preferably a servomotor.
  • the device 1 also comprises a control unit 9 configured to control the valve 7 to connect the pump 4 to the product tank 2, to control the pump 4 to draw from the product tank 2 a larger volume of solid food product than the first volume to be filled, and then output the excess volume back towards the product tank 2, to control the valve 7 to connect the pump 4 to the fill head 8, and to control the pump 4 to supply the first volume of solid food product to the fill head 8.
  • a control unit 9 configured to control the valve 7 to connect the pump 4 to the product tank 2, to control the pump 4 to draw from the product tank 2 a larger volume of solid food product than the first volume to be filled, and then output the excess volume back towards the product tank 2, to control the valve 7 to connect the pump 4 to the fill head 8, and to control the pump 4 to supply the first volume of solid food product to the fill head 8.
  • the control unit 9 may further be configured to control the operation of one or more pistons 5 and/or one or more motors 6 in order for the pistons 5 to cooperate with the pumps 4.
  • the control unit 9 may further be configured to control the operation of one or more fill heads 8 in order to activate the filling of the solid food product, to monitor and react to the feedback system, and/or to control the processing means as discussed previously.
  • the control unit 9 may be implemented as one or more processors (CPU) or programmable logic controllers (PLC). It may be a single unit or divided into several parts. One control unit 9 may be configured to control the operation of any number of valves 7, pumps 4, pistons 5, motors 6 and/or fill heads 8.
  • the control unit 9 may be fully automatic using feedback systems to control the device 1 in the most efficient manner.
  • the control unit 9 may have semi-manual control of variations such as package volume control using a user interface such as a control panel.
  • the control unit 9 is preferably configured to accurately control the motion profile of the piston 5; in terms of speed and acceleration, as well as in terms of defining the end positions of the piston 5 (i.e. the end position corresponding to the larger volume, and the intermediate position corresponding to the first volume to be filled).
  • the control unit 9 is communicating with the servomotor to follow a software profile adapted to each type of food particles being filled. Such control will improve the filling operation, in terms of accuracy and speed.
  • Fig. 2 shows another embodiment of the device 1, where two devices 1 are arranged with certain shared components in order to increase efficiency.
  • the skilled person will realise that any number of devices 1 may be arranged with any number of shared components.
  • Fig. 2 shows two pumps 4, each comprising a piston 5. While not shown, two or more pumps 4 may be arranged to share the same piston 5. Only one of the pistons 5 is provided with a motor 6, which in this embodiment is configured to actuate both pistons 5.
  • One fill head 8 is shown, each filling one respective package 10.
  • One fill head 8 may e.g. be arranged with several nozzles or openings, each being configured to fill one package 10.
  • the first volume to be filled corresponds 7to the volume of solid food product to be filled in only one package 10. In this case, it is preferred to use one fill head 8 per package 10 to be filled.
  • each pump 4 does not change between the pump 4 and the corresponding packages 10 to be filled.
  • Each fill head 8 may then be configured to fill exactly one volume to be filled into any number of packages 10, using known methods to ensure that each package 10 receives the same amount of solid food product.
  • Fig. 2 further shows two valves 7, each being connected to one respective pump 4 and one respective fill head 8.
  • Each of the valves 7 is however connected to the same product tank 2 (not shown). The skilled person will realise that more than one valve 7 may share any two or more connections.
  • valves 7 maintain a direct connection between a pump 4 and a corresponding fill head 8 to ensure that the first volume to be filled output by each pump 4 does not change as discussed above.
  • One control unit 9 is shown in Fig. 2 to control two valves 7, and one motor 6. While all of these components may be controlled by one control unit 9 each, the skilled person will realise that it may be more efficient to have one control unit 9 controlling all components as needed.
  • Fig. 3 shows a system 20 for filling at least one package 10 with solid food product.
  • the system 20 comprises a device 1 for filling at least one package 10 with a first volume of solid food product similar to the device 1 of Fig. 1 and will thus not be described further.
