With this washing line, tthe required standards of cleanliness and hygiene of the moulds that allow the continuous pressing cycles of ham and shoulder are achieved. Equipped with two sections, washing and rinsing, independent in their operation. Detergent dosing systems, self-cleaning filters and water heating by means of steam or heating resistors make up these machines that are capable of solving the problems of continuous washing of all types of moulds and lids with minimal water consumption by reusing the washing and rinsing with mains water. The equipment has two parallel conveyors, one for the moulds and the other for the lids. The cleaning of the moulds is done with closed circuit washing and rinsing directly from the mains.
