  • Patent number: 5762991
    Abstract: A continuous process of producing beer is described. Starch-containing raw materials are disintegrated and are optionally processed to form malt, a wort is produced from the disintegrated and optionally malted raw materials, and the wort is subjected to alcoholic fermentation. In that process all process steps are performed continuously. The mash is initially heated in a reactor system to a temperature of to C. The grain residue is removed from the mash. The wort is subsequently hopped and is heated to a temperature from to C. This is succeeded by a flash evaporation, a removal of the dregs and a cooling of the wort, which is subsequently fermented at to in the presence of a biocatalyst. The fermenting process may be succeeded by a partial or full continuous de-alcoholization of the beer.

  • Patent number: 5750179
    Abstract: A water-dispersible lipidic hop extract composition, comprising at least 10% by weight of free fatty acid substances derived from hops, is useful to increase the utilization of the hop aroma and flavor components. It may be produced by treatment of an extract of hops with an excess of alkali. The starting hop extract, made conventionally as by extraction with organic solvent or carbon dioxide, preferably has alpha, isoalpha, and beta hop acids removed before treatment with excess alkali. A cosolvent, such as a lower alkanol, polyol, or wetting agent, heat, or high shear may be used to improve mixing of the lipidic organic phase of the hop extract with the excess alkali. The water-dispersible lipidic hop extract imparts an enhanced hop aroma and flavor upon addition to the wort at some point during the brewing process between boiling and the beginning of fermentation. A beer incorporating the dispersible lipidic hop extract has a stronger hop aroma and flavor than beer incorporating the usual hop extract.

  • Patent number: 5744189
    Abstract: The invention relates to a method of ensiling fodder made by combining fresh or wilted silage material with solid carbon dioxide while utilizing the essential conditions for homofermentative lactic acid fermentation, which are known in themselves and the basic parameters of which can be monitored. The solid carbon dioxide is added in an amount of 0.5 to 20 kg per ton, preferably 1 to 3 kg per ton, according to a principle of distribution that gives priority to the zones of the silo most endangered by oxygen in the air, in particular the marginal zones. The fermentation process must take place with an amount of silage material large enough to be little affected by the ambient temperature.

  • Patent number: 5725894
    Abstract: A coccidiosis-relieving agent comprising cashew nut shell oil and/or anacardic acids as an active ingredient and a feed for relieving coccidiosis comprising cashew nut shell oil and/or anacardic acids. Cecal lesions of livestock and poultry, in particular poultry such as fowl, can be relieved by adding cashew nut shell oil and/or anacardic acids to a feed. The coccidiosis-relieving agent according to the present invention does not completely inactivate Coccidium protozoa, but induces slight infection to immunize an animal, thus achieving a so-called "passive immunological effect". The coccidiosis-relieving agent is efficacious in allowing Coccidium protozoa to grow and imparting sufficient immunological stimuli while relieving lesions to thereby lessen damage to poultry such as fowls.

  • Patent number: 5674364
    Abstract: A method and device in the regulation of the headbox of a paper machine/board machine, in which additional flows are introduced into the pulp suspension at different points across the width of the headbox. The concentration of the additional flows is different than the average concentration of the pulp suspension. The additional flows are introduced through additional-flow pipes to the vicinity of inlet openings of turbulence tubes of a turbulence generator. The grammage profile of the web in the direction of width of the web is regulated in the headbox by adjusting the distance of the end of the additional-flow pipe/pipes from the turbulence generator, whereby the amount of the additional flow entering into the additional-flow pipes and, at the same time, the amount of the pulp suspension flow are regulated.

  • Patent number: 5549788
    Abstract: Effluents are minimized from a cellulose pulp mill having a recovery boiler by concentrating liquid effluents from the bleach plant and/or liquid spills from process streams, incinerating the concentrated effluents in the recovery boiler, removing particles present in the flue gases from the recovery boiler to produce an ash including salts containing potassium and chloride, and sulfur compounds, and removing the potassium and chloride from the ash while returning the sulfur containing compounds to the recovery loop, so as to balance the sulfur, chloride and potassium levels in the mill. The sulfur is typically returned directly to a stream of black liquor just before entry into the recovery boiler. Green liquor is produced from the melt, which preferably is treated to remove metals from it prior to caustization (e.g. by sedimentation and/or filtration), and prior to green liquor crystallization to produce sodium hydroxide.

  • Patent number: 5547012
    Abstract: Kraft pulp of increased strength and bleachability may be produced with decreased consumption of effective alkali, and at a lower H factor, by keeping the dissolved organic material (DOM) concentration low substantially through the entire kraft cook, including by extracting high DOM liquid from at least one part of a continuous digester and replacing it with much lower level DOM liquid. Existing pulp mills having two-vessel hydraulic, one-vessel hydraulic, or other systems may be retrofit to provide for extractions and additions of low DOM dilution liquor (including substantially DOM-free white liquor). Also, commercial size batch digesters (8 tons per day of pulp or more) can be operated with low DOM liquor to produce increased strength pulp. Using dilution with low DOM liquor also results in reduced H factor and effective alkali consumption, and increased bleachability.
