Page 13: Operation
OPERATION GENERAL DESCRIPTION The blast chiller is a chilling machine capable of cooling the temperature of a freshly cooked product up to +3°C (positive chilling) and up to -18°C (negative chilling), in order to conserve it for a long period of time without altering the organoleptic characteristics. -
Page 14: Machine Loading
MACHINE LOADING Do not pile up foodstuffs to be cooled. Thickness should be lower than 50mm in negative quick cooling and lower than 80mm in positive quick cooling. 0.5 - 2 cm. Make sure air circulation is not hampered between food trays. The grid-holding frame (included in those models which include trolleys) is to be located at the center of the cabinet. -
Page 15: Temperatures
TEMPERATURES Do not leave the cooked products that are to be chilled/frozen at room temperature. Avoid humidity losses, which will be detrimental to the conserved fragrance of the product. We recommend beginning the chilling/freezing programme as soon as the preparation or cooking phase has ended, being careful to insert the product into the equipment at a temperature no lower than +70°C. -
