- A22C: PROCESSING MEAT, POULTRY, OR FISH (preserving A23B; obtaining protein compositions for foodstuffs A23J1/00; fish, meat or poultry preparations A23L; disintegrating, e.g. chopping meat, B02C18/00; preparation of proteins C07K1/00)

## Abstract

A meat processing machine comprises: a movable stand movable on a base stand with a block of meat set on it; a supporting stand provided above the base stand in such a manner as to be vertically movable; needle connecting members coupled to the supporting stand, the needle connecting members being arranged in a direction perpendicular to a direction of movement of the movable stand; a number of needles extended downwardly from each of the needle connecting members; lift drive means provided between the supporting stand and the needle connecting members, for lifting the needle connecting members to predetermined positions separately so that the needles of a selected one or ones of the needle connecting members are inserted into the block of meat; and a reciprocation drive means for moving the supporting stand vertically, for the purpose of cutting the sinews in the block of meat suitably which are not always uniformly distributed in it.

## Claims

### Claim 1

A meat processing machine comprising:
a base stand;
a movable stand movable on said base stand with a block of meat set thereon;
a supporting stand provided above said base stand in such a manner that said supporting stand is vertically movable;
a plurality of needle connecting members coupled to said supporting stand, said needle connecting members being arranged in a direction perpendicular to a direction of movement of said movable stand;
a plurality of needles extended downwardly from each of said needle connecting members;
first reciprocating means for reciprocating at least one of said needle connecting members in a direction perpendicular to a direction of movement of said movable stand;
second reciprocating means for reciprocating said supporting stand in said direction perpendicular to said direction of movement of said movable stand; and
horizontal drive means for selectively driving said movable stand horizontally forwards and backwards, said horizontal drive means provided on a lower surface of said base stand.

### Claim 2 (depends on 1)

A meat processing machine as claimed in claim 1, wherein said first reciprocating means reciprocates said needle connecting member which is selected from at least one of said needle connecting members to position said needle connecting member into a predetermined position, said needle connecting members being individually controllable.

### Claim 3 (depends on 1)

A meat processing machine as claimed in claim 1, wherein said horizontal drive means selectively drives said movable stand back and forth intermittently.

### Claim 4

A method for processing a meat, comprising the steps of:
horizontally moving said meat set on a movable stand selectively back and forth by horizontal driving means;
selectively reciprocating a plurality of needle connecting members each having a plurality of needles in a direction perpendicular to a direction of a movement of said movable stage, said needle connecting member being reciprocated by reciprocating means; and
sticking said needles provided on said needle connecting member which is selected from a plurality of said needle connecting members into a predetermined position of said meat, individually controlling said needle connecting members, to obtain said meat having a constant tenderness.

### Claim 5 (depends on 1)

A meat processing machine according to claim 1, further comprising a plurality of meat retaining boards, each of said meat retaining boards supported on each of said needle connecting members respectively, for holding said meat in place, wherein said needles pass through holes formed in said meat retaining boards, and wherein a height of each of said meat retaining boards is individually adjustable.

### Claim 6 (depends on 1)

A meat processing machine according to claim 1, wherein said needle connecting members are each provided with locking means, for preventing each of said needle connecting members from being moved towards said meat, respectively.
