Description

Water-saving preserved meat salt water injection device

Technical Field

The invention relates to the technical field of food processing, in particular to a water-saving type preserved meat brine injection device.

Background

When the preserved meat is produced, saline water needs to be injected inwards and the preserved meat needs to be rolled and kneaded, so that the quality and the taste of the preserved meat are improved. The traditional preserved meat is a two-step separated process in the steps of injecting saline water and rolling. The existing injection mode is roughly divided into two types, one type is to realize the up-and-down injection of the needle head through a hydraulic cylinder, the other type is to inject through manual operation, but two types all exist not enough, mainly embodied:

1. the conventional saline water injection equipment is provided with a plurality of needle heads, and in the injection process, due to the insertion angle and the meat quality, a part of needles are not really inserted into meat blocks, most of saline water sprayed by the needle heads runs off, so that waste is caused, and for this reason, the conventional equipment is specially provided with a collecting tank which is used for collecting the saline water for recycling; therefore, the phenomenon of salty taste inside out and light taste inside out of the preserved meat is caused, and the taste is influenced.

2. The traditional saline for injection can only be injected from the tail end of the needle, the needle is easy to block in the inserting process, and in the injecting process, the saline is deposited and expanded at the needle firstly and then is sprayed out along the path of the needle, most of the saline is lost, and only a small amount of the saline is retained in the meat block.

3. In the prior art, the mechanical injection and the manual injection are both performed only one surface and only once, which is not beneficial to the penetration of the surface spice into the meat block.

4. After the injection is finished, the meat blocks need to be put into a rolling and kneading machine for rolling and kneading, or the meat blocks are repeatedly flapped by utilizing equipment, so that the seasonings on the surfaces can permeate into the meat blocks, two steps are needed, and the cost is increased.

swing rods 8 are hinged to the left end and the right end of the flat plate 3, the lower ends of the swing rods 8 are close to each other and are in a V shape, a tension spring is connected between the lower ends of the two swing rods 8, a U-shaped plate 9 with a downward opening is fixed to the lower end of each swing rod 8, a cylindrical shell 10 arranged in the U-shaped plate 9 in the front-back direction is arranged, the two ends of the cylindrical shell 10 are hinged to the U-shaped plates 9, and a plurality of injection needles are fixed to the outer side wall of the cylindrical shell 10; the upper end of the frame 1 is provided with a water tank 12 with a water pump 11, and the water pump 11 can send saline water in the water tank 12 into the cylindrical shell 10 and spray out through an injection needle.

In order to prevent the saline waste and realize the injection of most saline into the meat, the injection needle comprises a needle main body 13, the end part of the needle main body 13 is blocked, a semicircular groove is arranged on the middle part of the needle main body 13, a rotating block 14 is hinged in the groove through a torsion spring, the rotating block 14 is in a semicircular shape matched with the groove, and a through hole corresponding to the cavity of the needle main body 13 is arranged on the rotating block 14; the rotating block 14 blocks the needle main body 13 without external force; when the groove is completely filled by the rotating block 14 due to external force, the through hole corresponds to the inner cavity of the needle head main body 13, and saline can flow through the through hole; the half part of the needle head main body 13 far away from the liquid storage box is provided with a fine liquid outlet hole.

In order to realize evenly patting, injecting all around the meat piece, 2 lower extremes of lead screw be fixed with rather than coaxial cam 15, cam 15 is located 5 upsides of harmonic speed reducer ware, lead screw 2 rotates and enables the swinging arms 8 of both sides round the pin joint rotation through cam 15, realizes patting the meat piece, also makes the meat piece can rotate along with couple 7 is smooth.

The upper end of the screw rod 2 is connected with a motor 16, and the motor 16 is fixed on the upper side plate of the frame 1.

It is noted that at the end of the cylindrical housing 10, an overflow valve is provided through which the brine can flow back into the tank 12 when the water pressure is excessive.

When the device is used, meat blocks are hung on the hook 7, the two cylindrical shells 10 approach to the middle under the action of the tension spring at the lower end of the oscillating rod 8 and clamp the meat blocks, then the motor 16 is started, the motor 16 rotates to drive the screw rod 2 to rotate, the screw rod 2 rotates to drive the flat plate 3 to move up and down through the nut on the screw rod, the flat plate 3 moves up and down to drive the oscillating rods 8 at two sides to move up and down, the oscillating rod 8 drives the cylindrical shells 10 to roll up and down on the meat blocks, in the rolling process, the rotating block 14 on the injection needle inserted into the meat blocks is pressed by the meat blocks, the rotating block 14 rotates for an angle and perfectly fills the grooves in the rotating block, at the moment, the through holes in the rotating block 14 are communicated with the cavity of the needle main body 13, salt water can flow through the through holes in the rotating block 14 and is finally discharged from a plurality of liquid outlets on the side wall of the needle main body 13 to inject the interior of the meat blocks until the injection needle head is separated from the meat blocks; the injection needle is drawn out from the inside of the meat block, the external pressure on the rotating block 14 disappears, and the rotating block 14 seals the needle main body 13 under the action of the upper torsion spring, so that the waste is avoided.

In the foregoing, lead screw 2 drives cam 15 and rotates, and cam 15 makes the continuous repeated injection extrusion to the meat piece of cylinder shell 10 of two swinging arms 8 lower extremes, also plays the effect of patting simultaneously, does benefit to later stage air-drying fermentation.

When the injection device is used for injection, the meat blocks slowly rotate at a constant speed, and the cylindrical shell 10 rolls up and down, so that the meat blocks are uniformly injected around.

According to the invention, the meat blocks can be flapped and punctured by the needle head at all angles, so that the meat blocks become soft; secondly, the more and more uniform the meat pieces are pricked, the easier and faster the spice on the surface of the meat pieces can permeate.

The injection needle of the present invention is specially designed wherein the position and angle of the rotor 14 relative to the needle body 13 is such as to control whether the needle is open to fluid. When the needle head is not inserted into the meat block or the needle head does not reach the depth of an expected value, the rotating block 14 seals the needle head; when the needle is inserted into the meat and reaches a certain depth, the rotating block 14 rotates a certain angle under the extrusion of the meat, and the needle is filled with liquid. In this way, a large amount of brine can be saved, leaving only the inside of the meat mass; the diffusion and the seepage of the saline water from inside to outside are realized in the true sense, and the brackish water outside and the bland water inside are avoided.

In the invention, the fine liquid outlet on the needle head main body 13 can discharge liquid, so that the blocking risk is reduced; the saline is evenly distributed along the path of needle insertion.

The invention realizes the combination of the injection and the rolling and kneading, reduces the enterprise cost and reduces the production difficulty.
