The continuous flow poultry meat system 100 has multiple stages including a supply stage 200, a transfer stage 300, and a feed sage 400, and a product discharge stage 500.

(9) In the supply stage 200, a gravity separation supply tank 202 is provided with a supply tank body 204. The supply tank body 204 includes a supply tank top 206 defining a supply probe aperture 208; a supply pressure aperture 210; and a supply vacuum aperture 212. The supply tank body 204 also includes a supply tank side wall 214 defining a supply infeed aperture 216, and a supply tank bottom 218 defining a supply output aperture 220. In the preferred embodiment, the separation supply tank 202 is thirty two inches tall with a diameter of twenty four inches. The supply probe aperture 208, supply pressure aperture 210, and supply vacuum aperture 212 are two inch sanitary fittings and the supply infeed aperture 216 and supply output aperture 220 are a six inch sanitary fittings. A six to ten inch conversion flange is connected to the supply output aperture 220.

(10) The product infeed 230 includes an infeed pipe 232 connected by an infeed check valve 234 to the supply infeed aperture 216. The infeed check valve 234 is a SAMSON Model No. 3310-07-A351CF8M six inch stainless flange air actuated ball valve available from SAMSON CONTROLS INC. USA, 4111 Cedar Blvd, Baytown, Tex. 77523.

(11) The supply pressure system 240 uses air supply line 12 to feed a supply tank pressure transducer 242 connected by a supply transducer air line 244 to a supply pressure enable solenoid valve 246. The supply pressure enable solenoid valve 246 is connected by a supply pressurizing line 248 to the supply pressure aperture 210.

(12) The supply level probe system 250 uses a probe body 252 with an extending probe rod 254 the drops into the supply tank body 204 to determine the height of meat in the supply tank body 204. The supply level probe 250 is a KEYENCE Model No. FL-S001 guide pulse type level sensor with a probe length of 23 inches. KEYENCE CORPORATION OF AMERICA, 500 Park Boulevard, Suite 200, Itasca, Ill. 60143, U.S.A.

(13) The vacuum draw system 260 uses the vacuum line 14 through a pneumatic valve 262 connected to the supply vacuum aperture 212. The pneumatic valve 262 is connected through vacuum control lines 263 including a vacuum valve input 264 and vacuum valve output 266 to the pneumatic vacuum actuator 267. The pneumatic vacuum actuator 267 is connected by the first solenoid line 268 and second solenoid line 270 to the vacuum solenoid valve 272 that is connected to the air supply line 12. The pneumatic valve 262 is a VLABIA Model No. 82DA1375 two inch actuated ball valve from VALBIA S.r.l., Via Industriale, 30, 25065 Lumezzane S.S. Italy

(14) The transfer stage 300 uses a transfer flow valve 302 connected between the supply output aperture 220 and the feed input aperture 412 on the feed tank 402. The transfer flow valve 302 is connected by transfer control lines 303 to the transfer pneumatic valve actuator 304. The transfer pneumatic valve actuator 304 is connected by the first transfer solenoid line 306 and the second transfer solenoid line 308 to the transfer solenoid valve 310 that is connected to the air supply line 12.

(15) The feed stage 400 includes a feed tank 402 with a feed tank body 404. The feed tank body 404 includes a tank top 406 defining a probe aperture 408, pressure aperture 410, and feed input aperture 412. The feed tank 402 also includes a tank side wall 414 and tank bottom 418 defining a feed output aperture 420. The feed tank 402 is forty six inches tall with a diameter of 36 inches and is mounted on casters for mobility. Note that the feed tank402 is larger than the supply tank 202 so that the feed tank can absorb the material from the supply tank 202 without overfilling, and can also absorb the pressure input moving the meat from the supply tank 202 to the feed tank 402. The feed output aperture 420 is a six inch sanitary fitting.

(16) The feed tank 402 is fed through the feed pressure system 440. The feed pressure system 440 uses the air supply line 12 to feed a feed tank pressure transducer 442 connected by a feed transducer air line 444 to the feed pressure enable solenoid valve 446. The feed pressure enable solenoid valve 446 is connected through the feed pressurizing line 448 to the pressure aperture 410. This maintains the feed tank 402 at a consistent 10 psi.

(17) The feed level probe system 450 uses a probe body 452 mounted to the probe aperture 408 to control the movement of the probe rod 454 to measure the meat level in the feed tank 402. The feed level probe 450 is a KEYENCE Model No. FL-S001 guide pulse type level sensor with a probe length of 40 inches. The prob system 450 provides the knowledge for when to fill the feed tank 402 and when the feed tank 402 gets low on meat.

(18) The product discharge stage 500 uses a discharge line 502 connected to the feed output aperture 420 to provide meat onto a conveyor belt 504 operated by a conveyor drive 506.
