A pasteurization tunnel and a method for pasteurizing beverage packs are described, wherein the beverage packs are conveyed on at least two decks lying one upon the other and sprayed with a heated spraying liquid from spraying pipes extending each transversely to the conveying direction of the beverage packs. According to the invention, the spraying liquid is guided through the spraying pipes of the one deck into the spraying pipes of the other deck. Thereby, the maintenance efforts for removing deposits in sections of the spraying pipes where the flow is weak can be reduced.

A method for regulating a transport velocity in a pasteurizer comprises regulating of the transport velocity by changing, such as reducing or increasing, the transport velocity, making a corresponding first change, such as reducing or increasing, of a first number of pasteurization zones by a second number, and making a corresponding second change, such as increasing or reducing, of a third number of cooling zones by the second number. A device for carrying out the method comprises: a pasteurizer having a first number of pasteurization zones and a third number of cooling zones, a transport device for transporting containers at a transport velocity, a control device configured for the changing of the transport velocity, making the corresponding first change, and making the corresponding second change.

The disclosure relates to a method for regulating a velocity of a conveyor belt of a container treatment machine, such as a pasteurizer, in a filling line having a plurality of machines, wherein the method comprises: monitoring a current output of the filling line; when it is determined that the current output falls below a predefined nominal output, operating the conveyor belt at an effective velocity by a timed operation of the conveyor belt at a nominal velocity for a first time period and with stoppage of the conveyor belt for a second time period. The disclosure further relates to a device for carrying out the method, wherein the device comprises a container treatment machine with a conveyor belt.

The disclosure relates to methods for operating a pasteurizing device for pasteurizing foods filled into sealed containers. The foods are treated in treatment zones by applying a tempered, aqueous treatment liquid to an exterior of the containers. The treatment liquid is re-supplied to at least one treatment zone for reuse via circulation circuit pipes of a circulation circuit. A partial flow of the treatment liquid is continuously removed from the circulation circuit and filtered by means of a membrane filtration means. Furthermore, a biocide is apportioned to the treatment liquid as process chemical, such that a concentration of the biocide does not exceed 0.4 mmol/L. In addition, a pH-regulating agent comprising at least one inorganic or organic acid is apportioned to the treatment liquid as process chemical, such that a pH value of the treatment liquid is set to a range from 3.5 to 7.0.

Apparatus and method for pasteurizing food products and ready meals in hermetically sealed packages (22) by means of microwaves, comprising a microwave chamber (14); a lower conveyor belt (20) for the packages (22); an upper conveyor belt (18), extending substantially horizontally and vertically movable, and a microwave source (16) located below the lower conveyor belt (20), the microwave chamber (14) being under atmospheric ambient pressure. The apparatus comprises a cooling plate (10) in close contact with the upper conveyor belt (18) so that during microwave heating the top of the package (22) is cooled to below the condensation point of water vapor and overpressure in the package is avoided.

A retort rice meal producing system includes a pressurized steamer mechanism performing a steam heating process on raw rice under pressurizing, a steamed-rice single granulation mechanism removing surface-layer moisture from the steamed rice processed for single granulation as being conveyed by a conveyer, a quantitative filling mechanism of measuring the steamed rice subjected to single granulation for each pack and filling a container with the steamed rice, a packing mechanism further filling the steamed-rice-filled container filled with the steamed rice with at least an amount of a liquid such as a rice-cooking liquid required for soaking and moisture absorption and air for allocating a head space, and sealing the container, a soaking/moisture-absorbing mechanism reversing a package of the sealed container a plurality of times and causing the rice-cooking liquid to be absorbed into the steamed rice, and a retort sterilizing apparatus.
