Abstract: The disclosure relates to a three-stage reciprocating compressor comprising pistons and suction and compression chambers in which a medium is compressed for each separate stage, which stages are connected in series and where a first stage is fluidly connected to an inlet for inlet of uncompressed or pre-compressed gas where the three-stage pistons move synchronously along a common axis in one connected unit such that the first and second stage suction and compression chambers share piston as well as cylinder wall, and having separate cylinder heads, a top headpiece and a bottom headpiece on each side of the piston, the third stage piston extending from a center of the first and second stage common piston and is passed through an opening in the cylinder head of the first stage suction and compression chamber, in extension of which is placed a third stage cylinder tube with a smaller diameter than a diameter of the cylinder for stage one and two, each stage fluidly separated by one or more one way valves, where

Abstract: A continuous flow pasteurization apparatus for a liquid product includes a pasteurization area divided into plural pasteurization zones, each with a connection for heating and/or cooling the product, so that if production stops, it is possible to hold the temperature below the pasteurizing temperature. Upon restarting, the product is reheated to a temperature close to the pasteurizing temperature. The apparatus provides for the control and monitoring of pasteurization units (PU's).

Abstract: A tunnel pasteurizer having a tunnel, through which the material to be pasteurized is conducted and sprayed or sprinkled with water, and with a trap region for the draining water arranged on the bottom of the tunnel, pasteurizer and a plurality of temperature zones arranged in the transport direction, and the trap region is divided into separate trap zones which correspond to the temperature zones, from which the water is re-supplied to the respective tunnel zones, and comprising a control means for controlling the water temperature in the temperature zones. To improve control of the temperature in the individual temperature zones, the control and the tubing of the trap zones is adapted such that water can selectively be taken from the individual trap zones for temperature control and can selectively be returned to other temperature zones, wherein water is buffered in the individual temperature zones separate from other temperature zones in a respective zone buffer.
