The present invention provides for an apparatus for converting an organic liquor into a mixture of hydrocarbons and carbon solids, comprising: a heater for heating the organic liquor, thereby producing a mixture of liquid and vaporized oil; a reactor for converting the mixture of liquid and vaporized oil into carbon solids, and a mixture of hydrocarbons and gases; a first cooler for accepting the carbon solids; and a second cooler for accepting the mixture of hydrocarbons and gases. The apparatus of the present invention finds application in the processing of waste and low-value products to produce useful materials in reliable purities and compositions, at acceptable cost, without producing malodorous emissions, and with high energy efficiency. In particular, the organic liquor derives from feedstocks such as offal, animal manures, municipal sewage sludge, tires, and plastics, that otherwise have little commercial value, and are thereby converted into useful materials including gas, oil, specialty chemicals, and carbon solids.

A method and apparatus for implementing pathogen reduction within a poultry processing or food processing plant that uses water that has been treated with chloramines at an advantageous dosage before being introduced to the production process at processing steps. The water treated with chloramines may be from a fresh water source or reclaimed water from the processing plant. The reintroduction of the treated reclaimed water advantageously causes a dramatic reduction in the levels of microorganisms associated with poultry processing, while substantially conserving water use.

In the processing of poultry, equipment, instruments, apparatus and / or water used in such processing, and / or carcasses and / or parts of poultry resulting from the processing of poultry, are disinfected with aqueous solutions of certain halogen-based microbiocides, especially certain bromine-based microbiocides. Described are the particular microbiocides used and the substantial advantages of using such materials, in some cases as concentrated solutions and in other cases as dilute solutions.

An antimicrobial, anti-bacterial processing aid, food additive and food ingredient is provided to inhibit cellular growth of known pathogenic, indicator and spoilage organisms, such as salmonella, stahphylococcus, listeria, e coli, and the like. The antimicrobial agent of the present invention is useful as a treatment for animal feed, a treatment for pre-harvest and post-harvest processing of foodstuffs, a treatment for cooked food subject to airborne contaminants and many other conditions in need of disinfectants and sanitizers. One of the primary benefits of the antimicrobial agent is that it inhibits the growth of bacteria that have become antibiotic resistant.

The invention discloses a biological modified straw adsorbent, and a preparation method and application thereof. The method comprises the steps of: crushing the straw to prepare a straw powder; mixing the straw powder with a synergistic agent and water, and inoculating microbial strain for modification to conduct fermentation; and after the fermentation, taking out the modified straw powder and drying to prepare the adsorbent. The microbial strain is Trichoderma viride CGMCC3.5455, Trichoderma koningii CGMCC3.2774, Aspergillus niger CGMCC3.4309, Rhizopus stolonifer CICC40317, and Trichoderma koningii CICC 40108. The invention uses straw powder as a carbon source to conduct solid fermentation, so as to produce the adsorbent. The production process does not produce wastewater, waste gas or waste residue, and is energy-saving and environment-friendly. The prepared adsorbent has strong capacity, and can be used for treatment of tanning wastewater and dyeing wastewater.

A method of controlling microbial contamination of poultry carcasses in the processing of poultry as food products is described. The method comprises contacting the carcasses with an aqueous medium containing an effective microbial inhibiting amount of active bromine resulting from the addition to the medium of (i) at least one 1,3-dibromo-5,5-dialkylhydantoinin which one of the alkyl groups is a methyl group and the other alkyl group contains in the range of 1 to about 4 carbon atoms or (ii) a solution thereof, or (iii) both of (i) and (ii). Such contacting inhibits contamination of the carcasses by microorganisms, even at least some bacteria that are resistant to antibiotics or antibacterials. Also described are improvements in a poultry chill tank containing an aqueous medium and a plurality of poultry carcasses in contact with the medium. Such improvements result from the presence in the medium of an effective microbial inhibiting amount of active bromine in the medium, which amount results from the addition to water before it enters the tank or while it is in the tank, or both, of (i) at least one of the above 1,3-dibromo-5,5-dialkylhydantoins, and / or a solution thereof.

The inventions of the present disclosure are directed to processes designed to recover water used in certain aspects of the processing of poultry, treat the recovered water to remove solids, fats, oils and greases, animal proteins and pathogenic organisms and to reuse the treated water for poultry processing operations. The processes described herein reduce bacteria and microorganisms associated with the poultry and reuse water. The present disclosure can be employed with an approach that includes unexpected positive results of reacting ozone and chlorine with water being treated for reuse to generate hypochlorous acid and / or other effective biocides. Ozone reacts with fats, oils, and greases, dissolved in the reuse water, to produce specific surface-active agents and surfactants which reduce the surface tension of the water which it is dissolved. The combination of these surface-active agents and surfactants and the biocides cause an extraordinary release and destruction of bacteria from the poultry carcass as well as the reuse water.
