Abstract: The invention relates to a method for rearing animals and in particular poultry or pigs that comprises supplying the animals with drinking water in order to water the animals, injecting oxygen and CO2 into the drinking water, before the drinking water reaches the animals, according to one of the following modes: two injections, one of CO2 and one of oxygen, are carried out simultaneously into the drinking water, or one injection, a mixture of oxygen and CO2, is carried out into the drinking water.

Abstract: Equipment for manufacturing pellets of liquid or pasty products, comprising a tunnel and comprising a conveyor belt capable of transporting the product to be processed in the equipment along a processing path that passes through the various zones of the equipment, wherein the conveyor belt is equipped with unitary moulds, or else unitary moulds are formed in the structure of the conveyor belt, wherein the equipment comprises a pellet demoulding zone situated at the outlet of the tunnel or immediately downstream of the outlet of the tunnel, the demoulding zone operating in a rotation zone of the conveyor, and wherein the structure of the belt allows each pellet to be automatically demoulded by ejection, the ejection being effected by a given element of the structure of the conveyor belt on account of opposing forces being applied to the walls of the mould in the demoulding zone.

Abstract: An installation for rearing animals includes an injector; a water inlet line and a gas inlet line arriving in the injector; a source of oxygen or a gas mixture including oxygen, capable of delivering oxygen into the gas line; and a water recirculation loop including: a water tank, at atmospheric pressure, to supply the injector with fresh water; a coil capable of receiving water charged with dissolved oxygen from the injector through a pump, wherein the coil creates a water/oxygen contact time; and an overflow valve, to have the water resulting from the coil passed in order to be able to direct the water entirely to the animals' watering or partially to the animals' watering and partially back to the water tank. A method for rearing animals includes boosting water with dissolved oxygen up to saturation for animals' watering.

Abstract: The invention relates to a method for anaesthetizing animals before slaughter, by the anesthetic action of gases or gas mixtures, operated in “batch” mode, in which the live animals, preferably put together in one or more cages, are placed in a lock chamber for treatment where the animals are brought into contact with anesthetic gas, following a cycle comprising several steps characterized by different contents of anesthetic gas, characterized in that at least one of the steps is carried out using gas recovered from the lock chamber and stored in at least one capacity (2, No. 1, No. 2 etc.) for temporary storage having a variable volume.

Abstract: The invention relates to a process for cooling the neck of bottles, wherein the neck of the bottle, positioned in the inverted position, is submerged in a mass of a solid heat-transfer medium, for example copper shot, which mass is cooled using a cryogenic fluid, for example liquid nitrogen, or else liquid CO2 or else a mixture of such fluids.

Abstract: Method for cooling a product, all or part of the cooling being carried out by contact of the product with a mixture of carbon dioxide snow (CO2) and liquid nitrogen.

Abstract: The invention relates to a preferably continuous method for precooking the surface of food products, characterized in that all or part of the surface of the product makes contact with the flame produced by a burner, the flame employed being an oxyhydrogen flame, preferably a hydrogen/oxygen flame.

Abstract: The subject of the invention is a method for shaping at least one food product by cryoextrusion, the extruder being provided with a double-walled jacket surrounding the extrusion screw and through which jacket a coolant flows, this jacket consisting of a single module or several independent modules, the cryoextrusion being temperature-regulated on the basis of a curve, determined for said product to be cryoextruded, representing, plotted on the X-axis, the difference D between the actual temperature of the product and the desired temperature setting for the product at the exit and, plotted on the Y-axis, the setting to be applied for the gas temperature at the exit of the module or modules, the curve being split into three linear zones: an abrupt (steep-slope) zone, around a difference D close to 0, surrounded by two quasi-plateau zones.

Abstract: The invention relates to a method for cooling materials, in particular food, in a cooling apparatus, the cooling being completely or partially carried out by contacting the materials with a cryogenic liquid. Said method is characterized in that the contacting is carried out by means of the injection of two cryogenic liquids, nitrogen and CO2. The liquid nitrogen and the liquid CO2 are injected either separately, into at least two injection points of the apparatus, or by mixing both cryogenic fluids at the injection point. The invention is of use if the apparatus being utilized is a mixing, batch mixing, or grinding chamber, with the injection being carried out into the body of the material in the bottom portion of the chamber.
