Abstract
Description
- This invention relates to apparatus for sizing a mix of randomly sized food pieces into pieces of a predetermined maximum length. More particularly, the invention relates to apparatus for separating elongated pieces of a food product from a mix of randomly sized pieces and cutting the elongated pieces to a desired maximum length.
- In recent years procedures have been developed for producing food products which resemble chunks of natural meat in appearance and texture. Such simulated meat chunks, which typically are formed of meat material and/or vegetable protein are desirable in both human and animal foods from the standpoint of aesthetic quality and consumer appeal as replacement for more costly natural meat chunks. Such simulated meat chunks may be produced by procedures, such as extrusion through a die orifice, which result in the formation of pieces having a relatively uniform size. Recently procedures have been developed for producing simulated chunks of natural meat having a random size distribution, that is, the chunks may range in size from about 1.25 cm or less to about 10 cm or more in length. While such randomly sized chunks are advantageous in that they more nearly simulate chunks of natural meat, the production of elongated chunks, this is, chunks having a length of more than about 5 cm makes it difficult to accurately fill the chunks into conventional packaging, such as cans, in a high speed commercial packaging operation. Thus, the elongated chunks are difficult to process in conventional filling equipment, and the presence of such elongated chunks makes accurate weight control of filled cans very difficult.
- An apparatus for sorting items into items of a predetermined maximum length according to the preamble of claim 1 is known from BE-A-434395.
- The present invention is directed to an apparatus for separating elongated simulated meat chunks from a mixture of smaller randomly sized chunks and cutting the elongated chunks into pieces of a predetermined maximum length, in a high speed commercial production operation, by providing for an apparatus according to the features of claim 1. Rotation of the cylindrical members brings each cutting blade into close proximity to, but not in contact with, a longitudinal bar of the first cylindrical member.
- A mix of randomly sized meat chunks is deposited onto the surface of the first cylindrical member from a feed conveyor mounted above the first cylindrical member. Meat chunks having a length smaller than the spacing between adjacent longitudinal bars of the first cylindrical member fall between the longitudinal bars. Elongated meat chunks that is, pieces which have a length greater than the spacing between adjacent bars, are retained on the outer surface of the longitudinal bars of the carrier drum, with the chunks extending across two or more adjacent bars. The elongated chunks are carried into the nip between the drums where they are cut to a desired maximum length by a cutting blade in cooperation with a longitudinal bar. When cut to the desired length, the pieces fall through the bars.
- Preferably the alignment means comprise a number of longitudinal partitions at the discharge end of the conveyor means so that the longitudinal axes of elongated meat chunks are aligned substantially parallel to their direction of travel.
- Preferably the meat chunks which fall through the bars, fall onto a take-away conveyor mounted below the first cylindrical member.
- The drawings represent embodiments of the invention, in which
- Fig. 1 is a top plan view of the sizing apparatus of the present invention.
- Fig. 2 is a front elevational view of the apparatus of Fig. 1.
- Fig. 3 is a side elevational view, partly in section, of the apparatus of Fig. 1.
- Referring now to the drawing, the sizing apparatus includes a
support frame 10 having mounted thereon a carrier drum 11 and acutting drum 12, which are journaled on parallelhorizontal shafts side plate 13 the frame. Carrier drum 11 has a plurality oflongitudinal bars 16 mounted in spaced relation around the periphery of a pair of opposedcircular end plates shaft 14. The bars 11 are mounted equidistant around the periphery of the end plates, with the bars being spaced apart a distance equal to the maximum desired length of the food chunks to be sized. For example, if the maximum length of the meat chunks is 5 cm, longitudinal bars are spaced apart 5 cm, on center, around the periphery of the end plates. The radius A of carrier drum 11 is such that an even number ofbars 16 are provided around the drum, with the specific number of bars depending on the desired capacity and throughput of the apparatus. - Carrier drum 11 is driven by
motor 19 throughsprocket 20, keyed to driveshaft 21, and sprocket 22, keyed toshaft 14, with the sprockets being connected bydrive chain 23.Motor 19 is provided with a standardvariable speed reducer 24 to rotate the carrier drum at a desired operating speed. - Cutting
drum 12 which is mounted vertically above carrier drum 11, has a plurality ofequidistant cutting blades 25 mounted around the periphery ofcircular end plates central support plate 28, all of which have the same radius, with the cutting edges ofblades 25 being spaced apart the same distance aslongitudinal bars 16 on the carrier drum. Thecutting blades 25 are mounted innotches 29 spaced around the periphery ofsupport plates wedges 30 and countersunk screws (not shown), with the cutting edges of the blades extending beyond the peripheral surface of the plates. The radius of the imaginary cylinder which is formed by the cutting edges of the blades is indicated at B. -
Blades 25 are mounted parallel toshaft 15 over substantially the entire length ofbars 16, with theblades 25 being aligned to cooperate with thebars 16 upon rotation of the drums in opposite directions (as shown by the arrows in Fig. 3) to cut elongated chunks carried on the upper surface of the bars into the nip between the drums. Preferably the cutting edge of each of theblades 25 is slightly inclined, with reference to the axis of theshaft 15, in the direction of rotation of the cutting drum. Thecutting drum 12 is aligned with the carrier drum 11 in a manner such that upon rotation of the drums in opposite directions, the cutting blades do not strike against the longitudinal bars. Rather, the leading edge of each cutting blade passes slightly behind the trading edge of a corresponding longitudinal bar, such as by about .0375 to .155 cm. -
Cutting drum 12 is rotated by means of drive chain 32 which extends aroundsprocket 33 mounted onshaft 14 of the carrier drum,idler sprockets shaft 15, so that cuttingdrum 12 will be rotated in a direction opposite to that of the carrier drum 11. According to a preferred embodiment, the circumference ofsupport plates cutting drum 12 being driven at a peripheral speed of two times that of the carrier drum 11. -
Vibratory conveyor 40 is mounted adjacent the upper section of carrier drum 11 with the longitudinal axis of the conveyor being perpendicular to the longitudinal axes of thebars 16 on the carrier drum, to deposit a mix of random sized meat chunks carried from a hopper (not shown) onto the upwardly rotating section of the carrier drum.Vibratory conveyor 40 includes a plurality oflongitudinal divider members 41 at the discharge end of the conveyor which are spaced apart a distance equal to the maximum desired length of the meat chunks in the mix to be sized, to align such elongated chunks with their longitudinal axes in parallel alignment with their direction of travel on the conveyor, as shown by the arrow in Fig. 1. In this manner, the aligned elongated chunks discharged fromconveyor 40 are deposited on the surface of the rotating carrier with the longitudinal axes of the elongated chunks being perpendicular to the axis of the longitudinal bars, so that the elongated chunk extend across two or more adjacent bars. Smaller sized chunks in the mix fall through the space between adjacent bars and through the carrier drum. Preferably, the upstream ends ofdivider members 41 are staggered in length to prevent bridging of the elongated chunks across adjacent dividers as the random sized mix is carried along the conveyor. - A take-
away conveyor 42, such as a conventional endlers belt or other suitable collection means, is mounted beneath the carrier drum 11 to receive small sized chunks which fall through the longitudinal bars, as well as elongated chunks which are cut to the desired maximum length by the action of cuttingdrum 12. The chunks deposited on theconveyor 42 are carried to suitable processing equipment, such as conventional fillers, or to storage.
