Abstract
Blood from a slaughterhouse is gelatinized in a gelatinizer by adding steam and heat thereto. The blood is blown by additional steam pressure from the gelatinizer into an auger press thereby force feeding the press. The gelatinous mass is first squeezed gently to remove the liquids therefrom and during the latter stages is pressed more firmly to remove more of the liquids. The liquids are directed to a filter tank, while the solid gelatinous mass is directed to an offal cooker with offal.
Claims2
A method of preparing blood solids from fresh blood for mixture with raw offal to make meat meal for animal feed comprising:
- a. charging blood and water into a gelatinizer, then
- b. gelatinizing the blood by
- (i) adding live steam, and
- (ii) adding heat, thereafter
- c. closing all outlets on the gelatinizer, then
- d. opening an exit valve of the gelatinizer, then
- e. injecting steam into the gelatinizer, thus increasing pressure in the gelatinizer until the gelatinous mass is forced through a blow pipe and thus force feeding an auger press, therein
- f. augering the gelatinous mass through a perforated cylinder,
- g. squeezing at least 50% of the moisture therefrom,
- h. exerting greater pressure on the gelatinous mass during the latter stages of augering than during the first,
- j. separating the gelatinous mass from the liquid,
- k. removing the gelatinous mass from the press, and
- m. transporting said gelatinous mass from the press to an offal cooker.
A slaughterhouse structure comprising gelatinizer and an auger press for processing blood having
- a. the gelatinizer in the form of closed vessel,
- b. a blood feed line entering into said vessel,
- c. a steam line connected to a source of steam entering into said vessel,
- d. a blow pipe exiting from said vessel,
- e. an exit valve in said blow pipe,
- f. a blood valve in the blood line,
- g. a steam valve in the steam line,
- h. the press having an auger mounted within a
- j. perforated and appertured cylinder,
- k. means for rotating said auger,
- m. said means for rotating said auger includes
- (i) an electric motor connected through a variable speed transmission whereby the speed of rotation of the auger may be varied,
- n. said auger having a mandril with flights thereon,
- o. said blow pipe entering into said auger press at
- p. a feed chamber on a feed end of the auger,
- q. said flights at the feed end being spaced wider apart than at the other end which is the press end of the press,
- r. said mandril having a smaller diameter at the feed end than at the press end,
- s. the feed chamber has a Y therein, and
- t. a gravity pipe entering said Y,
- u. said gravity pipe having a gate valve therein whereby material is gravity fed into said auger.
