How does the jam get into a berlin doughnut or a puff? Different flavors and fillings, e.g. speed can rise to 50 l / min. The barrel strawberry jam, eggnog cream or emptying from ViscoTec can perfectly chocolate pudding make the hearts of fulfill this criterion and supplies the line those with a sweet tooth beat faster. with sufficient filling material. The large bakeries face the challenge of meeting the high demand. Automatic The automated filling, directly from the production lines make it possible to tank into the hopper of the production supply these diverse fillings, which are line, facilitates the production process freshly prepared in boilers, to the pastry and the output of finished pastries is filling plant in a hygienic and highly much higher. efficient manner. As a result, there is no downtime in the The following example shows how this production line and the entire supply can be perfectly implemented: A German runs reliably. In addition, the user has the bakery uses the ViscoTec barrel emptying advantage that filling errors and wastage system ViscoMT-XL. This means that are avoided. fillings for Danish pastry and puff pastry, as well as berlin doughnuts, are By implementing different sensors (e.g. taken from 500 l tank and fed into the level sensors in the tank or pressure production line. The fillings have different sensors) the need to change the tank can viscosities: From liquid chocolate sauce be detected early and no production time to stiff vanilla cream to fillings containing is lost. pieces of up to 15 mm in size (such as cherry pastes). These sweet goods can Since the fillings are not exposed to therefore be filled with anything. their surroundings, there is no risk of contamination. One challenge facing process-reliable feeding is to supply the different fillings At the end of a preparation phase in to the line very quickly and at the same the tank, the fillings are immediately time ensure the output quantity of covered by the follower plate of the barrel pastries. Depending on the filling and the emptying system and are ready to be type of pastry, the demand and the feed filled into the pastry in a closed system. 38 FDPP - www.fdpp.co.uk Endless Piston Principle The progressive cavity pump forms the base of the barrel emptying systems from ViscoTec. It belongs to the group of rotary displacement pumps and is based on a volumetric pump technology. The operation is like an endless piston, which feeds the product from the suction side to the pressure side and thereby builds up a difference in pressure. The interaction of an eccentrically moving rotor and stator results in a feed and dosing characteristic that corresponds to that of an endlessly moving piston. Due to the dosing geometry, a constant volume is always fed proportionally to the rotation angle per revolution. The feed direction is reversible by reversing the direction of rotation. The volume is therefore clearly defined via the degrees of angle. To summarize, it can be said that the barrel or tank emptying from ViscoTec has many advantages. In addition to easy handling, the hygienic emptying of the mixing tanks should be highlighted. ViscoTec emptying systems offer the perfect process-reliable solution for the filling of pastries and doughnuts. [email protected] www.viscotec.de
