Abstract: The procedure to prevent the formation of condensation on tools that are heated in use and are cooled by a circulated coolant is particularly relevant to plastic moulding machines. To avoid the build-up of condensation from dampness on the cooled tools a dry air veil, as herein laid down, is produced by direct blowing-on of the tools, through which the cooling water temperature of the circulated coolant in the tools can be further reduced making shorter work cycles possible. By use of a special control equipment, the dew point on the tool surface is picked up which regulates the cooling water temperature accordingly.

Abstract: A storage and aging unit for meat and sausages includes a closed space for the meat and sausages and an air conditioning unit for circulating air in a closed cycle through the closed space. Inlet and outlet openings from the air conditioning unit are in direct communication with the closed space. A sterilizing unit is located within the air conditioning unit in the path of flow of the air between the inlet and outlet openings.
