FR2876017A1 - Food liquidiser has dished cutting disc with radial array of serrated teeth surrounding a central array of larger cutting teeth - Google Patents

Abstract

A liquidiser reduces fruit and vegetables to liquid form. The liquidiser has a reservoir with an inlet, a stopper, and a dished cutting disk. The disc has radially-arranged rows of serrated teeth extending from the outer margin to a zone near but not at the disc centre 'blind spot' circle. The disc 'blind spot' centre point has a number of larger teeth.

KNIFE BLADE OF A PRESS-FRUIT AND VEGETABLES

Prior art

Description of the prior art

  Figures 1 to 4 show a conventional structure of a fruit and vegetable press comprising a pusher 11, a lid 12, a rotating knife blade 13, a machine body 14, a container for residues 15 and a motor 16. The press -fruits cut the fruits and vegetables into small pieces, and the pusher 11 presses the food with the rotating knife blade 13 actuated by the motor 16. The extracted juice is filtered by the filter 132 and is collected. However, because of the variable (hard / soft) consistency of foods, some parts of fruits and vegetables can not be properly or completely crushed, or foods can not be crushed enough to extract juice. In addition, if the pusher 11 is forced down, the motor 16 could be overloaded, or the blind area D of the conventional juicer is produced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS With reference to FIG. 5, a fruit and vegetable squeezer is shown, comprising a pusher 2, a lid 3, a knife blade 4, a machine body 5, a container for residues 6 and a motor 7. The improvement according to the present invention relates to the knife blade 4.

  As shown in Figure 6, the knife blade 4 is conically shaped surrounded by a filter 41, and the crushed food juice flows through the filter 41. The upper end of the filter is mounted at the edge of the filter. upper part of a support 42. The lower base of the filter 41 is placed on the base housing 43, and the blade 44 is placed on the base housing 43 of the base inner part of the filter 41.

  The blade 44 is circular and is made of a metal. The upper portion of the blade 44 is radially disposed as a toothed blade 441 and the toothed blade 441 includes a plurality of small toothed blades 442 having a smaller blade body. The small toothed blade 442 has a semicircular housing section shape 4421 and tapers upwards. The section of the upper part of 4421 is projecting triangular shape. The toothed blade extends from the circumferential edge of the blade 44. The toothed blade 441 defines the central region of the blade 44, which constitutes the blind cutting region D. According to the present invention, the central region is provided with blades. with central teeth 443 having a wider blade body. The teeth blades 443 and the smaller teeth blades 442 have the same shape. But the blade body of the central teeth blades 443 is about 1.5 to 2 times wider than the smaller blade 442. The height of the central teeth blades 443 is about 1.3 to 1.7 times greater than the blade The direction of the teeth blades - 3 central 443 is divided into two groups and the direction of the blade of the group is opposite.

  As shown in FIG. 7, the center-tipped blade 443 is on a horizontal line and the direction of the blade defines two sets of center-tipped blades 443. When the knife blade 4 is actuated by a motor 7 to rotate, the central blade 443 has kinetic energy, which can crush the central part of the food. In practice, the center-tipped blade 443 may be arranged in a star-shaped cross arrangement.

  According to the present invention, the center of the blade-cut blind region D is provided with a plurality of separate center-toothed blades 443. The blade body and the height of the center-tipped blades 443 are wider than the blade. With the installation of the central teeth blades 443, when the knife blade 4 rotates, the center-tipped blade 443 of the central region of the blade 44 still has kinetic energy. The upper portion 4431 of the central teeth 443 crushes the central portion of the food into very small pieces, and by rotating the knife blade 4 to produce centrifugal force, the crushed food is thrown into the waste container 6.

  The height of the center-tipped blade is wider than the tine blade 441, it will crush the central portion of the food, and then contribute to crushing the food by the tine blade 441. The installation of the central teeth blades 443 eliminates the formation of the knife blade. This will improve the crushing efficiency of pressfruits and vegetables. The center-tipped blade 443 is formed from the blade 44 by punching. This will simplify the pressfruit blade module and reduce the manufacturing cost.
