Title: Method of and apparatus for processing animal material
IPC: A23K1/10
Filed: 1964-10-29
Abstract: Animal fat is processed to separate into meal, fat and stickwater and a portion of the stickwater and the meal are mixed to form pellets having a core of wet sticky meal and a cover of substantially dry meal, the pellets then being dried and granulated.  The separation is effected in an inclined cooker from which the meal is fed to a rotary drum dryer from which substantially dry low protein meal is extracted and fed to a hopper.  Some of the stickwater removed from the cooker is fed to a container attached to the meal containing hopper and is dropped on to meal being discharged from the hopper.  The wet meal is fed to a shaker unit comprising a series of three inclined plates the second and third of which are screened and all of which support transverse baffles which are of varying heights and some of which are perforate.  The mixture fed to the shaker unit works its way round the baffles and due to the continuous vibration they form wetted nuclei coated with dry particles which move through the perforations. The granules formed by this agglomerating process are fed back to the drier for further drying.

Abstract: 1,208,292. Loading a trailer with bales. NATIONAL RESEARCH DEVELOPMENT CORP. 23 Dec., 1968 [28 Sept., 1967], No. 44209/67. Heading B8E. A trailer for collecting and transporting bales comprises a conveyer elevator 5 feeding to the trailer which has a deck 8 raisable and lowerable as each tier of bales is loaded. The elevator is connected to a tractor at its lower end by a tie rod which keeps it a spaced distance away and at its top end by a ball member raisable in a slide on the trailer by an hydraulic ram which engages a socket member 33a. A compacting member 26 mounted at the top of the elevator is actuated by an hydraulic ram 29 to compact a complete file of bales which then engage a yieldable member 44. Endless chains 20, Fig. 3, passing over wheels 22, 22a at each end of the trailer are driven by an hydraulic motor 24 and are connected by an apron consisting of rollers 23 extending the length of the trailer. In use with the right end of the apron, Fig. 3, positioned to receive a first file of bales and the deck 8 fully raised the tractor is driven to pick up bales. When a complete file has reached the trailer the driver pulls a lanyard to operate a valve to actuate the compactor which causes the file to depress the member 44 which operates a further valve to start the motor 24 to advance the apron and with it the file of bales. When the file clears the member 44 the motor 24 stops and the cycle is repeated to feed in the next file of bales. When a complete tier of bales has been formed feed of the apron will not clear the member 44 as the first file has reached the far side of the trailer and thus feed of the apron will continue so that the bales fall on to the deck 8 as the apron clears them to the right and as it travels down the right side of the trailer it will contact a trip lever which causes the deck 8 to drop one bale height in which position it is arrested by cam action. The cycles can then be repeated after the motor 24 has been reversed to restore the apron to its original position.
