Definitions

  • the present invention relates to a vertical batch freezer.
  • this batch freezer is of removable tub type and is specifically used to produce pasty food products such as, for example, ice creams and similar products.
  • vertical batch freezers comprise a tub open on top and provided with a base on which a through hole is obtained, a refrigeration cylinder provided with a cavity inside which the tub is removably housed, a pair of paddles, or scraping blades, to stir the food product, and actuating means to rotate the two paddles within the tub.
  • the actuating means comprise a motor equipped with a drive shaft for transmitting the rotary motion to the two stirring paddles.
  • the removable tubs of such batch freezers once introduced in the housing of the refrigeration cylinder, are locked to the frame of the batch freezer so that during the rotation of the paddles, or scraping blades, inside the tray, the latter does not start rotating or may accidentally lift axially from the housing in which it is located.
  • Patent US4583863A in the name of Brevetti Gaggia Spa describes a batch freezer comprising a frame, a tub open on top for containing the food product to be batch frozen, at least one refrigeration cylinder provided with a cavity inside which said tub can be removably housed, a pair of grip elements to remove/introduce the tub into the cavity and transport it, and fastening means to reversibly prevent the rotation and/or translation of the tub with respect to the frame of the batch freezer, at least when the tub is housed in the cavity of the refrigeration cylinder.
  • These locking means comprise two pins integral with the frame of the batch freezer and two slots obtained on the upper perimetrical edge of the tub. This slot is made with a shape such as to allow, on one side, the head of the respective pin to enter therein and, on the other side, to prevent the exit of the pin head once the tub is slightly rotated with respect to the cavity.
  • Patent US4538427A in the name of Cavalli describes a batch freezer in which the fastening means comprise four first radial projections integral with the tub and likewise four second radial projections integral with the frame of the batch freezer but at greater height with respect to the first radial projections integral with the tub.

  • the batch freezer 1 further comprises fastening means 6 to reversibly prevent the rotation and/or translation of the tub 3 with respect to both the frame 2 of the batch freezer 1 and, as a result, the refrigeration cylinder 4, at least when the tub 3 is housed inside the cavity 4a of the refrigeration cylinder 4.
  • the reversible fastening means 6 comprise two retaining elements 7 and two hooking elements 8 for the two retaining elements 7. These two hooking elements 8 are integrally constrained to the plane 2a of the frame 2 and project upwards therefrom.
  • each retaining element 7 is movably constrained with respect to the tub 3 between a position PI (see Figures 2 and 5) of disengagement from the respective hooking element 8, in which the tub 3 is removable, or removed, from the cavity 4a, and a position P2 (see Figures 3 and 5) of engagement with the respective hooking element 8, in which the tub 3 is locked to the frame 2.
  • the two retaining elements 7, in particular, are arranged in diametrically opposite parts of the tub 3. In practice, these two retaining elements 7 are located at a longitudinal radial plane of the tub 3 on which the longitudinal axis Y of the tub 3 lies.
  • the tub 3 is further provided both with a base 3b on which a through hole 3c is obtained and, at the through hole 3c, with a tubular sleeve 20 sealingly connected to the base 3b of the tub 3. Furthermore, the tub 3 is provided with a pair of stirring paddles or scraping blades 21 to stir the food product by rotating inside the tub 2 around the sleeve 20.
  • the actuating means for the two paddles 21 comprise not only an electric motor not shown in figures though known to the field technician, but also a drive shaft 22 for transmitting the rotary motion to the two stirring paddles 21. Furthermore, the batch freezer 1 also comprises means 23 for the integral and removable connection of the two paddles 21 to the drive shaft 22. It should be noted that the two paddles 21 mentioned above are not further described here since they are known to the field technician. They can be made in very different geometries and sizes without thereby departing from the protection scope of the present invention.
  • the tub 3, in order to be introduced/removed into/from the cavity 4a of the refrigeration cylinder 4, has substantially frustoconical shape.
  • the angle between the side walls 3d and the base 3b of the tub 3, with respect to the longitudinal axis Y, is between 0.5 and 3°, where the area of the base 3b is smaller than the area of the top opening 3e of the tub 3.
  • the batch freezer 1 also comprises heat adjusting means arranged inside the refrigeration cylinder 4 and near the tub 3, in order to adjust the temperature of the food product being processed.
  • These temperature adjusting means comprise refrigeration means 101 and controlling means 102 to control the temperature in the containing tub 3.
  • the cooling means comprise, in a known manner, a tube bundle 101 traveled by a coolant and arranged on the outer surface 4b of the cavity 4a of the refrigeration cylinder 4 such that, at least when the tub 3 is housed in the cavity 4a, these tubes of such tube bundle 101 are in front of both the outer surface 3d of the tub 2 and the base 3b thereof.
  • the retaining elements 7 comprise a grip element 5 for moving also the retaining element 7 between the engagement position P2 and the disengagement position P 1 , and vice versa.
  • the grip element 5 is intended not only to introduce and remove the tub 3 into/from the cavity 4a, but also to actuate the two retaining elements 7 and move them to the two engagement P2 and disengagement PI positions, and vice versa.
  • each retaining element 7 is rotatably constrained to the tub 3 to rotate around a horizontal pivot 60 integral with the upper edge 3 a of the tub 3.
  • the pivot 60 rotates around the horizontal axis X. Since there are two retaining elements 7, there are also two pivots 60 sharing the same axis of rotation X.
  • each retaining element 7 can be engaged with the respective hooking element 8 in a position outside the tub 3.
  • the retaining element 7 rotates around the pivot 60, therefore around the axis X, outside the tub 3.
  • the upper edge 3 a of the tub 3 is also shaped to abut against the upper plane 2a of the frame 2 when the tub 3 is housed inside the cavity 4a.
  • each retaining element 7 comprises a first hook 7a and each hooking element 8 comprises a second hook 8a to couple to the respective first hook 7a.
  • This first hook 7a and this second hook 8 a cooperate with each other along a direction T substantially tangential to the upper opening 4c of the cavity 4a of the refrigeration cylinder 4. This allows the tub 3 to better resist possible moments which it could be subjected to during the operation of the batch freezer 1.
  • each retaining element 7 has at least one main body 7b having a curvilinear surface 7c shaped to eccentrically rotate with respect to the center C of the horizontal pivot 60 so that, at least for part of the rotation of the first retaining element 7 from the engagement position P2 to the disengagement position PI, this curvilinear surface 7c is in contact with the upper plane 2a of the frame 2 to raise the tub 3 upward with respect to the cavity 4a, at least when the first hook 7a is not engaged with the second hook 7b.
  • Figures 5 and 6 show the axial displacement E of the tub 3 with respect to the upper bearing plane 2a of the frame 2 and, therefore, of the cavity 4a, when the retaining element 7 is rotated from the engagement position P2 to the disengagement position PI.
  • the grip element 5 comprises a handle.
  • This handle 5 is constrained to the two retaining elements 7 at its own two ends 5 a.
  • this handle 5 has a substantially semicircular shape and, moreover, is made in one piece with the two retaining elements 7.
  • the handle 5 is in a substantially horizontal position, i.e. parallel to the bearing plane 2a of the frame 2, outside the tub 3 itself.
  • the handle 5 when the retaining elements 7 are in their disengagement position PI, the handle 5 is on a plane on which the longitudinal axis Y of the tub 3 lies. In practice, therefore, the handle 5 is in a substantially vertical position, i.e. rotated by 90° with respect to its position when the retaining elements 7 are in their engagement position P2.
