An integrated system of technology applications and methods to provide comprehensive management of poultry waste improves the productivity of poultry housing facilities while reducing the environmental and public health impacts of poultry production. The method utilizes a plurality of housing units, each including plenum flooring and ventilation to improve the health of birds as they grow from hatchlings to market size adults. After the birds are removed from the housing units, manure is immediately removed from the flooring system and preferably transported to a processing facility. The units are cleaned and fumigated with ozone so that they are ready to receive a new flock within approximately 48 hours from removal of the preceding flock.

A food processing and/or packaging device comprises at least one food chamber. Via a conduit system, the at least one food chamber is connected to a vacuum pump for generating vacuum in the at least one food chamber. For sterilizing the conduit system and/or the food chamber, a sterilization device is provided. The sterilization device comprises e.g. spray nozzles for introducing cleaning liquid into the conduit system. The cleaning liquid is separated by a liquid separator arranged upstream of the vacuum pump in flow direction.

A UV microorganism inhibiting device that includes a housing having an interior, and a front and back that defines a length; at least one UV light source located within the interior of the housing; a pressurized air source to produce pressurized air; an inlet for introducing pressurized air into the interior of the housing; a reflective surface within the interior of the housing; and an outlet opening for allowing UV light and an air and ozone mixture to pass from the interior of the housing to outside the housing.

The present disclosure is directed to a method for reducing bacteria in a precipitated calcium carbonate (CaCO.sub.3) slurry, the method including: adding water to calcium oxide (CaO) to form Ca(OH).sub.2; treating the Ca(OH).sub.2 with CO.sub.2 gas to form a slurry including precipitated CaCO.sub.3; neutralizing the slurry; and exposing the slurry that was neutralized to ozone in an amount sufficient to reduce bacteria in the precipitated calcium carbonate slurry. Oral care compositions including the precipitated calcium carbonate of the disclosed process are also described.

A ventilation system includes a line system which is designed to guide an air stream and to provide the air stream during normal operation via an outlet of the line system for supplying a space. The ventilation system includes a generating unit which is designed to produce reactive oxygen species during a cleaning operation and to feed the same to the air stream conducted in the line system. Also disclosed are methods for operating such a ventilation system and a generating unit for such a ventilation system.

The present disclosure provides a method for preparing an amino acid composition using an animal byproduct, particularly a method for obtaining an amino acid composition of high quality using an animal byproduct more effectively in short time. Because an amino acid composition can be obtained from an animal byproduct more effectively and quickly using the method of the present disclosure, utilization of livestock waste, etc. can be enhanced and application as various products can be expected.

A swab canister (101) is provided which includes a container (103) equipped with a first opening (105) and having a removable sample collector (117) disposed therein. A membrane (111) which is permeable to both moisture and a sanitizing agent such as ethylene oxide is disposed between the sample collector and the first opening. A desiccant (113) disposed between the membrane and the first opening.

A sanitizing device used to sanitize a bulb syringe. The device preferably includes a base, a bulb receiver, and a sanitization system. The sanitization system produces a sanitizing gas that is propelled into and possibly around a bulb syringe in order to sanitize the surfaces of the syringe. The sanitization system preferably includes an ionization module, a fan, electrodes, and a power supply. Preferably, the sanitization system is housed in a conical housing which includes a central nozzle and an array of openings centered around the nozzle exit. The sanitization device preferably includes an automatic switch that is activated by the presence of a bulb syringe or upon placing a cover over the device.

Systems and methods for detecting presence of a thing, the thing treated with a descenter, one method including in an area in which it is possible that a thing treated with a descenter is present, using a detector to detect a descenter level in the area, producing a detected descenter level, comparing the detected descenter level to a normal descenter level for the area, determining that the detected descenter level is different from the normal descenter level, said determining indicating the possible presence of a thing treated with a descenter; and using a trained service animal to facilitate such a method.

A system for sanitizing and deodorizing garbage chutes using methane sensors in the trash chute that includes an ozone generating unit at the bottom of the trash chute. The system can include an ozone sensor as a safety device to ensure that ozone levels do not surpass a predetermined amount. The present invention works with a controller that controls the ozone generator based on a schedule program for a predetermined time of day. The present invention in an embodiment can include a plurality of additional sensors such as airflow detectors, occupancy detectors and the like.
