Bertrand Puma – Levain Processor




Bertrand Puma by Pavailler  has been a supplier of starter equipment to TMB Baking for over 20 years, with consistent satisfaction from our bakery customers. The PAVAILLER range leaven processors are machines for the making and the conservation of liquid leaven, to be mixed into different dough preparations.  The use of liquid leaven in bread making shortens the dough mixing time and improves the bread crumb structure – Thanks to the use of liquid leaven, the dough better accepts the
mechanization (suppleness, molding) – In function of the amount used, the flavor and savoriness of the product will vary.
