Abstract
Description
- This invention relates to cutting blade assemblies for hydraulic food cutting apparatus. More particularly it relates to a cutter blade assembly which defines a core area and a peripheral scrap area wherein the core area of the food product is cut into a recognizable decorative form.
- Many food products, and particularly vegetables and fruits are processed prior to sale either by canning or freezing. Unless the product involved is of a naturally occurring edible size, for example peas, the product is usually trimmed and sliced, or diced, to edible size prior to preservation processing such as canning or freezing.
- These slicing, dicing and other cutting operations have traditionally been accomplished with mechanical cutters. However, relatively recent advances in food product cutting technologies has resulted in the common use of hydraulic cutting apparatus which can be used to cut relatively huge quantities of food product at very high speeds. Cutting capacities of 13.600 kg to 22.700 kg per hour are not unusual.
- In a typical hydraulic cutting apparatus wherein potatoes are to be cut, they are dropped into a tank filled with water and then pumped through conduit into an alignment chute wherein the potatoes are aligned and accelerated to high speed before impinging upon a cutter blade assembly where the potato core is cut into a plurality of smaller pieces. Hydraulic cutting apparatus, or as they are known in the trade, hydroknives, can be utilized to cut extremely high volumes of potatoes if the potatoes can be properly aligned and accelerated to high speed immediately prior to impact with the cutter blade assembly.
- FISHER, ET AL., Patent No. 4,372,184, discloses a cutter blade assembly for use in coring a potato.
- Quite obviously there are a variety of applications for hydraulic cutter knives other than just for potatoes. Some of these would include beets, pickles, carrots, apples, pineapples and literally a host of other edible food products.
- None of the prior art discloses or teaches a method of utilizing a hydroknife apparatus for cutting the core of a potato into a decorative form so as to enhance the marketing value of the processed food product, such as fish-shaped french fries for fast food seafood restaurants. Or, to enhance the edible appeal of the product in relationship to a particular market group such as alphabet french fries for small children.
- Decorative shaped food products have been developed and successfully marketed for many years. However, as a universal rule, they are formed products as opposed to directly cut from food product in original cellular form. Examples include cookie and pasta dough which is then either extruded and then cross sliced or sheet cut by cookie cutter type apparatus. The direct cutting of a decorative shape of a product core, which can then be cross sliced has not been attempted before.
- Accordingly, it is an object of this invention to produce a cutter blade assembly which can be utilized in a hydraulic cutting apparatus to cut the core of food product passing through the cutter blade assembly into a decorative, recognizable shape.
- This object is achieved by use of a cutter blade assembly wherein a plurality of strip knives are utilized to define peripheral segments of the longitudinal passageway which result in a residual cross sectional core area having a particular decorative shape.
- Because of the dynamic forces associated with the impact of the product against the strip knives, and the need to frequently sharpen the strip knives, it is not practical to fabricate the complete form from a single strip knife in cookie cutter fashion. Instead, the perimeter frame is subdivided into a number of parallel sequential planes, each containing strip knives which define particular segments of the peripheral area.
- End tabs on the strip knives are inserted into notches in the perimeter frame and are held firmly in position to minimize wobble by compression of said tabs inserted into the perimeter frame from the strip knives when the various sections of the perimeter frame are bolted together.

Potatoes 17 are dumped into the water filled receivingtank 20.Food pump 21, usually a single impeller centrifugal pump, draws its suction from receivingtank 20, and pumps water and the suspendedpotatoes 17 from the tank intonozzle gun 22. -
Nozzle gun 22 functions as a venturi which is used to accelerate and alignpotatoes 17 immediately prior to impinging upon the knife blades ofcutter blade assembly 10. Depending upon the product being cut, its size, core density arid physical characteristics, normal speeds at the point of impingment upon the knife blades ofcutter blade assembly 10 range from 12,2 metres per second to 18,3 metres per second. - The cut product, which in this case is a decoratively shaped
potato core 18, and theperipheral scrap 19 exitcutter blade assembly 10 intodeceleration loop 23 which in effect is the second half of the venturi. The deceleration loop returns to a point above receivingtank 20 where the water, cutcores 18 andscrap 19 are deposited ontochain separator 24. The water passes throughchain separator 24 and returns to receivingtank 20.Chain separator 24 is typically an endless loop chain or dewatering shaker which is used to mechanically remove the potatoes from the hydraulic cutting apparatus assembly. Thedecorative cores 18 andscrap 19 are then usually mechanically separated by means of a sizer conveyor, not shown. Thecores 18 are then sliced, again usually mechanically, into appropriate thicknesses for further processing by blanching, freezing and packaging for sale. - The cutter blade assemblies in use today normally run at capacities of 13.600 kg per hour to 22.700 kg per hour, and can be operated at capacities of up to 45.360 kg of product per hour. During the course of an eight hour work shift, that represents a relatively huge amount of food product passing through the cutter blade assembly, and as a result, strip knives are removed for reshar- pening about once per eight hour work shift.
- Referring to Figs. 2, 4 and 5, my cutter blade assembly, in an embodiment designed to produce a potato core in the shape of an M, as shown in Fig. 3, is disclosed. In order to produce the decorative M, as is shown in Figs. 2 and 3, a plurality of strip knives must be utilized to cut away peripheral segments of the potato in order to define an M in the core area of the potato. The end tabs of
strip knives 15 as is shown in Figs. 4 and 5 are inserted intonotches 14 ofrings strip knives 15 to define various segments of the longitudinal passageway, the residual cross sectional core area can be shaped into a variety of recognizable decorative forms. In the case of a decorative M as shown in Figs. 2, 3, and 4, six strip knives are required, and result in a core in the form of a decorative M and up to twelve separate peripheral areas. Referring to Fig. 2,whole potato 17 is schematically represented at the point where it is just about to impinge upon thecutter blade assembly 10. It can be seen thatpotato 17 will be cut into a potato core having a cross sectional shape of an M and twelve separate peripheral scraps. - Fig. 5 is a representational side view which shows a feature of my invention which results in a minimization of wobble of the strip knives in the cutter blade assembly. The end tab sections of
strip knife 15 are slightly elevated above the plane surface ofring 13 so that when all of the rings containing the strip knives are bolted together by use of bolts passing throughholes 10,strip knives 15 will be tightly clamped into place. - This design, as is shown in Figs. 4 and 5 results in a cutter blade assembly which can be quickly disassembled for purposes of removing and sharpening
strip knives 15. - Figs. 6 through 10 show other configurations of the strip knives which are designed to produce decorative shaped cores in a variety of different configurations. Figs. 6 and 7 disclose strip knife configurations which result in a decorative core in the shape of fish. Fig. 6 uses six strip knives to configure the core in the shape of a single fish. It requires the use of three sectional rings to hold six strip knives. Fig. 7 discloses a strip knife configuration which results in the product core being cut into two decorative fish sections, and requires the use of eight strip knives and four ring sections. Figs. 8, 9 and 10 disclose other configurations of strip knives which result in core shapes in the forms of an A, X and K. In practice it has been found that virtually all of the letters of the alphabet as well as decorative geometric shapes such as stars and triangles can be easily produced by varying the configurations of the strip knives.
