Description

Technical Field

[0001] This utility model relates to the field of slaughtering and processing technology, and in particular to an operating table for processing high-quality large intestines in slaughterhouses. Background Technology

[0002] Pig intestines, a product of pig slaughter, are delicious after cooking and are enjoyed by many; however, cleaning them has always been a major challenge. Conventional cleaning mainly involves removing feces and odorous mucus. Due to the characteristics of pig intestines, such as their softness, slipperiness, and numerous folds, cleaning them thoroughly, especially to remove all traces, is extremely difficult. Although there are some specialized cleaning machines for pig intestines, such as patent document CN112841094A (publication date May 28, 2021, invention title: An Automatic Pig Intestine Cleaning Machine), the cleaning is not thorough. For example, the folds are often not cleaned, and the high-speed rotating brushes can easily damage the mucous membrane, causing further fecal contamination. Therefore, currently, manual cleaning of pig intestines is still the most common method.

[0003] As people's demand for healthy eating increases, and given the growing concern about obesity, some who used to enjoy pig intestines are gradually avoiding them. This is because the intestinal fat wasn't properly removed during cleaning, making the intestines too greasy after cooking. Therefore, to improve the flavor of pig intestines and satisfy people's appetites, we've added a step of removing the intestinal fat after cleaning, providing the market with premium pig intestines.

Detailed Implementation

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of the present invention.

[0028] like Figures 1-5 As shown in the figure, this embodiment provides an operating table for processing high-quality large intestines in a slaughterhouse. It can be used for the industrialized, efficient, assembly-line cleaning of large intestines from animals such as pigs, cattle, and sheep. The operating table 1 includes a manure cleaning station 2 and an intestinal oil removal station 3. The manure cleaning station 2 includes a drain trough 21, and the intestinal oil removal station 3 includes a drainage trough 31. Both the drain trough 21 and the drainage trough 31 are located inside the operating table 1, facilitating quick and convenient transfer to the intestinal oil removal station 3 after cleaning. Supporting flanges are provided on the four walls of both the drain trough 21 and the drainage trough 31. A grid plate 5 is placed on each of the drain troughs 21 and the drainage trough 31 based on these supporting flanges. The grid plate 5 can be used to hold containers for large intestines or intestinal oil, or directly as a worktable for holding large intestines.

[0029] The drain outlet at the bottom of the drain tank 31 is equipped with a filter screen 311 to prevent intestinal oil from flowing into the wastewater pipe and causing blockage.

[0030] The workshop may be equipped with multiple operating tables 1. Above each operating table 1 is a high-pressure water main pipe 22 and a negative pressure main pipe 32. Below the high-pressure water main pipe 22 is a water cannon horizontal pipe 23 connected by a water pipe. The water cannon horizontal pipe 23 is located above the sewage trough 21. Below the negative pressure main pipe 32 is a negative pressure horizontal pipe 33 connected by a pipe. The negative pressure horizontal pipe 33 is located above the drainage trough 31. The water pressure inside the high-pressure water main pipe 22 and the negative pressure inside the negative pressure main pipe 32 are both adjustable.

[0031] To facilitate cleaning the large intestine when removing intestinal fat, a faucet 4 is installed above the negative pressure horizontal tube 33, and a flexible hose 41 is connected below the faucet 4.

[0032] To facilitate the insertion of the large intestine into the horizontal pipe 23 of the water cannon, and to increase water pressure and change the direction of water jet for better flushing of fecal matter from the intestinal wall, the inlet of the horizontal pipe 23 is equipped with a nozzle 24 to enhance the pressure of the sprayed water and change the direction of the water jet. The front end of the nozzle 24 is conical, with water jet holes densely distributed on both the top and circumferential surfaces. The rear end of the nozzle 24 is cylindrical, and a protruding retaining ring 241 is provided on the outer circumference of the cylinder. The retaining ring 241 has a cross-section of less than or equal to a semicircle, and is used to prevent the large intestine from falling off when it is turned inside out and secured.

[0033] The negative pressure horizontal tube 33 is designed to facilitate the removal of intestinal fat. Its front end is equipped with a stop sleeve 34 to prevent the large intestine from being sucked in. The stop sleeve 34 is open from front to back, and its front end is a bowl-shaped cavity 341 that can accommodate the large intestine. The bottom of the bowl-shaped cavity 341 is equipped with an air suction hole 342.

[0034] The nozzle 24 and the stop sleeve 34 are both made of polyurethane and are fixedly connected to the inlets of the water cannon horizontal pipe 23 and the negative pressure horizontal pipe 33, respectively.

[0035] In addition, in order to prevent the water flow from the horizontal pipe 23 of the water cannon from washing the sewage outside the sewage trough 21, the sewage trough 21 is provided with a detachable baffle 6 opposite to the pipe opening of the horizontal pipe 23 of the water cannon.

[0036] The operation process of the control panel in this embodiment is as follows:

[0037] 1. Slide one end of the large intestine, from which feces have been squeezed out, onto the water cannon tube 23 through the nozzle 24. At this time, the large intestine is not turned inside out. During the sliding process, the water valve of the water cannon tube 23 is opened. While sliding, the large intestine is squeezed and pushed downwards, so that the fecal matter inside the large intestine is flushed down by the high-pressure water flow until the entire large intestine is covered by the water cannon tube 23. Then, the water valve is closed. The process of sliding and pushing the large intestine while rinsing with water can be repeated multiple times to completely clean the fecal matter inside the large intestine.

[0038] 2. On the inside of the retaining ring 241 of the nozzle 24 (near the side of the water cannon horizontal pipe 23), tie the tail of the large intestine to the nozzle 24 with a cable tie or rubber band, and then pull the large intestine outward to detach it from the water cannon horizontal pipe 23. Because the tail of the large intestine is fixed to the nozzle 24 and cannot be detached, the large intestine will be turned inside out during the process of pulling it off, so that the inner wall of the large intestine with intestinal fat is exposed.

[0039] 3. The cleaned and turned large intestine is placed onto the negative pressure horizontal tube 33, and the tail of the large intestine is inserted into the bowl-shaped cavity 341 of the stop sleeve 34. The negative pressure inside the negative pressure horizontal tube 33 is used to suck the tail of the large intestine.

[0040] 4. Starting from the tail end of the large intestine (the part fitted into the opening of the negative pressure horizontal tube 33), cut off the intestinal fat. Place the cut-off fat in a basin. Slide the large intestine, now free of fat, downwards out of the negative pressure horizontal tube 33 and into the basin placed below it. Continue cutting off the fat while sliding the large intestine downwards. Once all the fat has been removed, slide the large intestine off the negative pressure horizontal tube 33. Finally, pull the tail end of the large intestine out of the bowl-shaped cavity 341. The large intestine, now free of fat, has been turned inside out again.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model, and for the convenience of describing the technical solution, the front, back, left, right, top, middle, and bottom orientations are based on the accompanying drawings and are not a limitation on the protection scope of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the essence and scope of the technical solution of this utility model.
