English to Portuguese Science Food & Drink Pasteurizacao

O tema geral do texto é a fabricacao de queijo, e este item trata mais especificamente da pasteurizacao do leite. A seguir o texto original:

Application example: mozzarella
Regular cheesemilk pasteurisation is performed at
75°C for a duration of 20 seconds using a plate heat
exchanger with a tubular holding cell. Following
pasteurisation, cheesemilk is cooled to 37°C and
pre-incubated with a regular mozzarella starter
culture for 60 minutes, followed by the addition of
calcium chloride (CaCl2) and rennet. (...)

Pelo o que eu pesquisei, plate heat exchanger seria intercambiador/ trocador de calor a placas (por favor, corrijam-me se estou errada). Qual seria a traducao correta de tubular holding cell?
