Definitions

  • the invention relates to a food handling apparatus having locking devices for sealing a door of the food handling apparatus.
  • Food processing is a technology that sets high demands on process hygiene and quality, and typically involves several complex activities such as emulsification, pasteurization and mixing, all performed in large-scale food processing equipment.
  • Paddle mixers are used in food industry due to the combination of high sanitary standards and the need for mixing or dispersing high quantities of e.g. powder and liquid ingredients into a liquid medium to efficiently achieve a smooth, homogenous product with consistent quality.
  • Paddle mixers are large instruments and may be equipped with twin shaft paddles.
  • a food handling apparatus that comprises: a container; a door for allowing access to the container; and at least one locking device for sealing the door against the container.
  • the locking device comprises a stationary sliding pin and a rotational unit arranged to receive the sliding pin, wherein either the sliding pin or the rotational unit is arranged on the door whereas the other is arranged on the container.
  • the rotational unit comprises a base portion and a handle for rotating the base portion in relation to the sliding pin, the base portion comprises an engagement for slidable engagement with the sliding pin, and the engagement surface is inclined such that a force applied on the sliding pin by the engagement surface gradually increases when the base portion is rotated in relation to the sliding pin, to thereby press and seal the door against the container.
  • the food handling apparatus is advantageous in that it provides an ergonomic solution for opening large, heavy doors without using any tool.
  • the food handling apparatus may comprise several, such as at least five, locking devices of the same type for sealingly closing the door to the container.
  • the design of the locking devices may provide for a single operator to quickly open a two meter wide door without the use of any tools.
  • the locking device of the food handling apparatus may be designed with few or no threads within the container. This is advantageous since threads may wear down over time and be a source of contamination.
  • the engagement surface may have a curved shape as seen in the rotational plane of the base portion.
  • the engagement surface may comprise a first part having a first inclination and arranged where the sliding pin enters and slides into the engagement surface
  • the engagement surface may thus be inclined with respect to the rotational plane of the base portion. This facilitates an gradually increased force being applied on the sliding pin by the engagement surface when the base portion is rotated in relation to the sliding pin. With such a shape of the engagement surface, there may be an even pressure applied on a seal that may be used between door and container when the locking device is transferred form an open to a closed position.
  • the engagement surface may comprise a second part having a second inclination and arranged at an end of the engagement surface, after the first part as seen in a rotational direction of the base portion.
  • the second inclination may be opposite the first inclination, such that the force applied on the sliding pin by the engagement surface decreases when the sliding pin enters the second part, thereby providing a self-locking mechanism when the sliding pin has entered the second part.
  • the self-locking mechanism thus provides for the door being firmly in place once the locking device has been transferred to its closed position. Further, with the self-locking mechanism, a certain threshold force is required on the handle when the locking device is in its closed position in order for the sliding pin to slide out of engagement with the engagement surface, i.e. for the locking device to be transferred back to its open position.
  • the sliding pin may comprise a plastic portion, e.g. comprising PEEK (polyether ether ketone) on which the force from the engagement surface is applied.
  • the engagement surface may comprise a metal, such as stainless steel.
  • Using a plastic portion that slides on a stainless steel surface may give rise to a friction that is within a preferred interval, i.e. it may at the same time provide sliding of the pin on the engagement surface and prevent the pin from accidentally sliding out of engagement with the engagement surface.
  • the sliding pin may be of metal whereas the engagement surface, or at least part of the engagement surface, may comprise a plastic, such as PEEK, to provide a desired plastic-to-metal friction coefficient.
  • the food handling apparatus is in this embodiment a paddle mixer 1 having a container 2 and a large door 3 for accessing the container 2 via opening 19.
  • the door 3 and the container 2 are thus arranged to be closable against each other.
  • the paddle mixer further comprises twin paddles 21a, 21b for mixing large amounts of powdery material.
  • the paddle mixer 1 comprises a plurality of locking devices 4 for sealing the door 3 against the container 2. In this case, the paddle mixer 1 comprises nine locking devices 4, more or less evenly distributed around the opening 19 to the container 2.
  • each locking device 4 comprises a stationary sliding pin 5 and a rotational unit 6 for receiving the sliding pin 5 as the locking device 4 seals the door 3 to the container 2.
  • the sliding pins 5 are in this embodiment arranged on the door 3 and the rotational units 6 are arranged on the container 2.
  • the rotational units are arranged on a flange 14 of the container 2 that surrounds the opening 19 of the container 2, whereas the sliding pins 5 are arranged on the outside surface of the door 3.
  • the rotational units 6 locking devices 4 are arranged on the surface 14b of the flange that faces the door 3.
  • the positioning of the rotational elements 6 and the sliding pins 5 could be the other way around, i.e. so that the rotational elements 6 are arranged on the door 3 and the sliding pins 5 are arranged on the container 3, for example on the flange 14.
  • the paddle mixer 1 comprises a seal 12 that surrounds the opening 19 to the container 2 and provides a sealing function as the door 3 is pressed to the container 2 by the locking devices 4.
  • the rotational unit 6 of locking device 4 comprises a base portion 7 that is arranged on the container 2 via a bearing 22 arranged in the flange 14.
  • a handle 8 is welded to the base portion 7 and is used for rotating the base portion 7 in relation to the container 2 via the bearing 22.
  • the base portion 7 and bearing 22 are thus arranged so that the base portion 7 can rotate in a rotational plane parallel to the surface to which the base portion 7 is attached via the plain bearing, i.e. the outer surface 14b of flange 14.
  • the handle 8 allows for rotation of the base portion 7 relative to the sliding pin 5 around rotational axis A perpendicular to the outer surface 14b of the flange 14.
  • the locking device 4 may be transferred from an open position in which the door 3 is not sealed against the container 2 and the sliding pin 5 is not in engagement with an engagement surface 9 of the base portion 7, to a closed position in which the door 3 is sealed against the container 2 and the sliding pin 5 is subjected to a force from the engagement surface 9. Transfer between open and closed position is achieved by rotation of the handle 8 to make the sliding pin 5 enter and engage the engagement surface 9.
  • the sliding pin 5 is arranged on the door 3 close to the outer circumference of the door 3 so that it may be easily received by the rotational unit 6 upon rotation of the handle 8.
  • the sliding pin 5 is held in place on the door 3 by pin housing 5a that surrounds a base of the sliding pin 5.
  • the interaction between sliding pin 5 and the engagement surface 9 is further described in relation to Figs. 4-7 .
  • Fig. 3 illustrates the locking device 4 when it is in its closed position and the door 3 is firmly pressed against the container 2.
  • the locking device 4 comprises a stop pin 10 (see Fig. 2 ) that co-rotates with the base portion 7 upon rotation of the base portion 7.
  • the locking device 4 also comprises a stationary plug 18 that is arranged to engage the stop pin 10 when the locking device 4 is in the open position, thereby preventing further rotation of the base portion 7.
  • the stop pin 10 and the stationary plug 18 provides an "open stop" function so that an operator opening the door 3 becomes aware of when the sliding pin 5 is not longer engaged by the engagement surface 9, i.e. when the locking device 4 has been transferred to its open position.
  • the open stop pin 10 is in this example arranged to extend in a direction other than the direction of the handle 8, such as a direction perpendicular to the handle 8. This may facilitate the function of the stop pin 10, e.g. by allowing the stop pin 10 to engage the stationary plug 18 arranged on the flange 19.
  • the stop pin 10 and the stationary plug 18 are arranged on a first side 14a of the flange 14 and the base portion 7 is arranged on a second side 14b of the flange 14 that is opposite the first side 14a.
  • the door 3 may also be arranged on the second side 14b of the flange via suitable hinges.
  • the first side 14a may be a side not facing the door 3
  • second side 14b may be a side of the flange 14 that faces the door 14. Consequently, the handle 8 is arranged on the outside side 14b of the flange 14, i.e. on the same side of the flange 14 as the door 3.
  • the base portion 7 comprises a shaft 15 extending through the flange 14 for providing co-rotation of the stop pin 10 upon rotation of the base portion 7.
  • the shaft 15 is connected to the base portion 7 and the bearing 22 is formed as a hole in the flange 14, at a position where the shaft 15 extends through the flange 14. This allows for rotation of the base portion 7 relative the flange 14 upon rotation of the handle 8 around rotational axis A extending through the shaft 15.
  • the shaft 15 is surrounded by plastic portions 16, 17 on both sides of the flange 14. These plastic portions 16,17 are arranged to engage the surfaces of the flange 14 upon rotation of the base portion 7.
  • the flange 14 may be made of metal, such as stainless steel, and the plastic portions 16, 17 may reduce the friction against the flange 14 upon rotation of the handle 8.
  • the plastic portion 17 arranged to be on the same side of the flange 19 as the handle 8 is a plastic washer that may have friction reducing agents incorporated in its plastic composition.
  • the plastic portion 16 arranged to be on the same side of the flange 14 as the stop pin 10 may have the principal shape of a washer, also having friction reducing agents incorporated in its plastic composition.
  • the paddle mixer 1 further comprises a seal 12 that is arranged between the container 2 and the door 3 when the locking device 4 is in its closed position.
  • the seal 12 is in this embodiment a lip seal that is pressed between door 3 and container 2 upon closing of the door 2.
  • the seal 12 may be made of silicone.
  • the seal 12 is arranged around the whole circumference of the opening 19 to the container 2 so that a proper seal is formed between the door 3 and the container 2.
  • the seal 12 rests against an outer surface 23 of the container 3 that is located between the second side 14b of the flange 14 and the opening 19 to the container.
  • the seal 12 is held in place by a plurality of seal pins 13 having shoulders 20 that are pressed into the seal 12 to secure the position of the seal 12 when the door 3 is open.
  • the seal pins 13 may be arranged on the outer second surface 14b of the flange 14 so that the shoulders 14 are pressed into the seal 12, to thereby press the seal 12 against the outer surface 23 of the container 2.
  • the outer surface 23 is in this case perpendicular to the second side 14b of the flange 14.
  • the seal 12 may be a lip seal that comprises a base portion 12a and a lip portion 12b.
  • the lip seal 12 may then be arranged such that the lip portion 12b seals between the door 3 and the container 2, and the seal pins 13 are pressed into the base portion 12a of the lip seal.
  • the lip portion 12b may have a tip shaped cross-section, i.e. it may have a cross-section that becomes more and more narrow the further away from the base portion 12a it gets. This may facilitate compression of the seal 12 when closing the door 3.
  • the locking device 4 comprises a stationary sliding pin 5 and a rotational unit 6 arranged to receive the sliding pin 5, and the rotational unit 6 comprises a base portion 7 and a handle 8 for rotating the base portion 7 in relation to the sliding pin 5.
  • the base portion 7 further comprises an engagement surface 9 for slidable engagement with the sliding pin 5, and this engagement with the sliding pin 5 transforms the locking device 4 from an open to a closed position.
  • the engagement surface 9 is located in the base portion 7, which may be rotated in a rotational plane by handle 8.
  • This rotational plane is thus parallel to e.g. the second side of the flange 14b when the rotational unit is arranged on the flange 14, or parallel to the door 3 if the rotational unit is arranged on the door.
  • the rotational unit 6 may thus be rotated around rotational axis A that extends perpendicular to the handle 8 and through the shaft 15 of the base portion 7.
  • the engagement surface 9 is inclined such that a force applied on the sliding pin 5 by the engagement surface 9 gradually increases when the base portion 7 is rotated in relation to the sliding pin 5, to thereby press and seal the door 3 against the container 2. Consequently, the engagement surface 9 is inclined with respect to the rotational plane of the base rotational unit 6. This inclination may at an average be in the order of 3,5 to 6,2 degrees to provide a suitable increase in the pressing force applied to the sliding pin 5 upon transferring the locking device 4 from its open to its closed position.
  • the engagement surface 9 and the sliding pin 5 may further be arranged and/or dimensioned so that a predetermined frictional force is obtained between the sliding pin 5 and the engagement surface 9.
  • the engagement surface 9 may comprise a concave shape as seen along the extension of the engagement surface 9. This may allow for a suitable friction against e.g. a rounded sliding pin 5, i.e. a sliding pin 5 having a convex outer surface that slides and is pressed against a concave engagement surface 9.
  • the engagement surface 9 typically has a curved shape as seen in the rotational plane of the base portion 7.
  • the engagement surface 9 is curved as seen in the projection of the rotational plane of the handle 8. This is for allowing a smooth movement of the sliding pin 5 within the engagement surface 9 when the handle 8 is rotated.
  • the engagement surface 9 may comprise a part that has a partially helical shape that extends a certain number of degrees around the helical axis, such as between 90 and 270 degrees.
  • the engagement surface 9 may thus as a whole be partially helically shaped to extend a certain number of degrees around the helical axis, which in the illustrated embodiment is the rotational axis A.
  • the engagement surface 9 has in the illustrated embodiment a first part 9a having a first inclination ⁇ and arranged where the sliding pin 5 enters and slides into the engagement surface 9.
  • This first part has a partly helical shape with a helical axis that is aligned with the rotational axis A of the rotational unit 6.
  • the first part 9a spirals around rotational axis A.
  • the first inclination ⁇ has an angle of 3,5 to 6,2 degrees.
  • the first inclination angle ⁇ allows for a suitable increase in the pressing force applied to the sliding pin 5 as it enters and slides along the first part 9a of the engagement surface 9.
  • the engagement surface 9 has a second part 9b having a second inclination ⁇ and arranged at an end of the engagement surface 9, after the first part 9a as seen in the rotational direction R of the base portion 7.
  • the second part 9b is arranged about 135 degrees from the beginning of the first part 9a of the engagement surface 9, i.e. a sliding pin 5 will be pressed against the first part 9a of the engagement surface during a 135 degree turn of the handle 8 before entering the second part 9b having the second inclination ⁇ .
  • the second inclination ⁇ is opposite the first inclination ⁇ , such that the force applied on the sliding pin 5 by the engagement surface 9 decreases when the sliding pin 5 enters the second part 9b, thereby providing a self-locking mechanism when the sliding pin 5 has entered the second part 9b.
  • the second inclination ⁇ being "opposite" the first inclination may be understood as second inclination ⁇ having a negative angular value while the first inclination ⁇ has a positive angular value (or the other way around).
  • the absolute value of the second inclination ⁇ may be less than the absolute value of the first inclination ⁇ .
  • the first inclination ⁇ may have an angle of 3,5 to 6,2 degrees
  • the second inclination ⁇ may have an angle of -2,2 to -4,8 degrees.
  • the sliding pin 5 is, as seen along the axis of rotation A of the base portion 7 and when the engagement surface 9 slidably engages the sliding pin 5, located between the base portion 7 and a support member 14 that supports the base portion 7.
  • the support is accomplished by the base portion 7 being, either directly or indirectly via the shaft 15, connected to the support member 14.
  • the support member 14 is in this embodiment the flange 14 that extends around the opening 19 to the container 2.
  • a distance D between the engagement surface 9 and the support member 14 gradually decreases when the sliding pin 5 slides along the first part 9a of the engagement surface 9 upon rotation of the base portion 7, to thereafter increase when the sliding pin 5 enters the second part 9b of the engagement surface 9. This provides the locking mechanism of the device 4.
  • the rotational unit 6 comprises the shaft 15 that defines the axis of rotation A of the base portion 7, and the engagement surface 9 comprises a partially helical shape with an end portion 9b that is, as seen in a longitudinal direction of the handle 8, located between the shaft 15 and the handle 8.
  • the axis of rotation A is thus perpendicular to the extension of the handle 8.
  • the engagement surface 9 has its end portion 9b located at in the base portion 7 close to where the shaft 8 is welded to the base portion, and the engagement surface 9 has its start at least 90 degrees, as seen in the rotational direction R of the base portion 7, from its end portion 9b.
  • the base portion 7 is partly cylindrical and has a circular shape as seen in the rotational plane of the rotational unit 6, with a center line, illustrated by C in Fig. 7 , parallel to the axis of rotation A but shifted relative the axis of rotation A.
  • the center C of the base portion 7 is shifted so that it is not aligned with rotational axis A but instead located between the shaft 15 and the position of the base portion 7 from where the handle 8 extends. This shift makes the rotational unit 6 more compact.
  • Figs 8 and 9 illustrates the sliding pin 5.
  • the sliding pin 5 comprises a plastic portion 11 on which the force from the engagement surface 9 is applied. This plastic portion 11 is thus pressed by the engagement surface 9.
  • the base portion 7, as well as the engagement surface 9, the handle 8 and the shaft 15 of the rotational unit 6, may comprise a metal, such as stainless steel.
  • the plastic portion 11 may thus be pressed against an engagement surface of metal, such as stainless steel, upon opening and closing of the locking device 4.
  • the interface between the plastic portion and the stainless steel may provide a suitable friction coefficient upon rotation of the handle 8 and sliding of the sliding pin 5 against engagement surface 9.
  • the plastic portion 11 may comprises PEEK (polyether ether ketone). This polymer has for the described locking device 4 been found to provide suitable friction against the engagement surface 9.
  • the plastic portion 11 may have a rounded outer surface, as seen in Figs 8 and 9 . This may further facilitate the sliding motion against the engagement surface 9.
  • the rounded surface may have a radius that is from 8 mm to 12 mm.
  • the locking device 4 is free of any threads but may still efficiently be transferred from an open position to a closed position. Being free of threads is advantageous especially when it comes to handling powdery material, since the powder may be stuck on or between small surfaces of threads.
