Description

Carcass surface subtracts even spraying device of fungus liquid on line is slaughtered to livestock

Technical Field

The invention relates to a device for uniformly spraying a surface bacteria-reducing liquid on a carcass on a livestock slaughtering line, which is particularly suitable for uniformly spraying the surface bacteria-reducing liquid on the carcasses of large animals such as pigs and cattle and belongs to the field of livestock product processing.

Background

Modern livestock slaughtering enterprises can not only generate a large amount of bone chips, minced meat and bloodstain on the surface of the carcass in livestock slaughtering and subsequent head and half removing operations, but also easily pollute the carcass in production equipment, slaughtering tools, operating personnel, production environment and the like, especially in summer high-temperature seasons, the carcass is easier to breed microorganisms, and the food safety and sanitation problems are very easily generated while the shelf life is greatly shortened. Relevant experimental research shows that the liquid-passing covering mode is adopted to cover a layer of edible organic acid on the surface of the carcass, so that the growth of microorganisms can be inhibited, the total number of bacterial colonies can be reduced, and the shelf life of the carcass can be effectively prolonged. However, if the method is adopted to carry out liquid covering on a plurality of batches of carcasses in the same batch of organic acid, secondary pollution is easily caused, and if different batches of carcasses are subjected to liquid covering by adopting different batches of organic acid, resource waste is easily caused.

Detailed Description

The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the principles of the invention.

As shown in the figure, the utility model provides an even spraying device of carcass surface subtracts fungus liquid on livestock slaughtering line comprises spray assembly, actuating mechanism and control system, and wherein spray assembly includes nozzle 3, spray lance 4, and actuating mechanism is pneumatic type piston pump, including the pump body 16, piston 13, piston rod 6, and control system includes PLC controller 12, travel switch 8, limit switch 7, its characterized in that: in the spraying component, a limiting rod 9 for limiting the ascending height of a nozzle is welded on a spray rod, a cylinder at the bottom of the nozzle and at the top of a piston rod is of an external thread structure, a hole in the spray rod, which is connected with the nozzle and the piston rod, is of an internal thread structure, the spray rod, the nozzle and the piston rod are all connected through threads, in a driving mechanism, a piston divides a pump body into an upper bacteria liquid cavity 5 and a lower air cavity 14, the spray rod and the piston rod are hollow round tubes with communicated inner holes, a plurality of piston rod liquid inlet holes 11 communicated with the bacteria liquid cavity are arranged at the bottom of the piston rod, the driving mechanism is obliquely arranged below a body, the initial position of the spray rod is slightly lower than the body, and the oblique installation angle theta of, wherein l is the perpendicular component of cylinder push rod stroke, and a is the minimum interval of adjacent trunk on slaughtering line, and among the control system, the PLC controller passes through the wire and is connected with travel switch and limit switch respectively. When the carcass enters a spraying area along with the hanging frame 2 on the guide rail 1, the hanging frame extrudes and is connected with the travel switch 8 to send a spraying operation signal to the PLC controller, the PLC controller controls the air cavity 14 of the driver to intake air from the air cavity air inlet 15 to push the piston, the piston rod, the spray rod and the spray nozzle to obliquely move upwards, and the bacteria liquid in the bacteria liquid cavity 5 of the driver is compressed and then enters the piston rod and the spray rod through the liquid inlet hole 11 of the piston rod to be uniformly sprayed on the surface of the carcass through the spray nozzle. When the spray rod rises to a certain height, the upper limit rod 9 is connected with the limit switch and gives a spraying stop signal to the PLC controller, the PLC controller controls the air cavity of the driver to release pressure, the nozzle, the spray rod and the piston rod move downwards under the action of self weight, and the bacteria liquid cavity sucks new bacteria liquid under the action of negative pressure. The process is repeated in this way, and the operation of uniformly spraying the sterilization liquid on the surface of the moving carcass on the slaughtering line is completed.

The above embodiments do not limit the present invention in any way, and all technical solutions obtained by taking equivalent substitutions or equivalent changes fall within the scope of the present invention.
