'ZWA’ SERIES AUTOMATIC WAFER BAKING MACHINES

The automatic wafer baking machines of the ZWA series are suitable for the production of first class quality flat wafers. These machines can be Equipped with 12, 18, 24 30 & 36 baking plates(tongs) according to the required output. The machine is built with a steel frame of rigid construction. An endless chain conveys the baking plates on their carriers through the baking chamber driven by a chain drive infinitely variable in speed through its range.
The standard size of the baking plates is 290mm x 460mm (about 11 ½” x 18”). Also, special size of baking plates can be supplied on request. These baking plates can easily be exchanged to produce wafers of different designs. The oven can be heated by L.P.Gas or if preferred by Electricity.

Batter
Wheat flour, Maize starch, Vegetable fat, preservatives etc are mixed with water to form the wafer batter. The batter is discharged onto the baking plates by a cam operated pump. The pump can be very accurately set to give an efficient distribution of batter with maximum economy and minimum wastage. Adjustment, clearing and maintenance of the pump is simple and quick.

Baking Plates	The plates are made of special alloy. The selection of alloy and casting procedure ensures dimensional stability, a homogenous and dense surface, thermal stability, good heat accumulation characteristics and excellent thermal conductivity. Special finishing is done to ensure trouble free release of wafer sheets. The wafer thickness is quickly and easily adjusted by applying spacing shims.
Heating (either by liquified petroleum gas or electricity)	The gas heating system has automatic ignition with safety devices. In the case of gas, air or power failure, a automatic cutout device on the heating system will operate. The oven is equipped with special burners. Precise controls for the mixture of gas and air gives high efficiency combustion. On gas heated machines, the exterior of baking plates have pyramidal shapes cast-on, to give increased surface area and thus better heat exchange.
Feeding and Sheet Take-Off	The batter is discharged onto the baking plates by a cam operated pumps. The precision-built pump gives an efficient distribution of batter. Air blowing facility for simple removal of the wafer sheet from the baking plates.

Drive and Controls

The control panel can be mounted at the discharge end of the oven or at a distance of upto one meter for ease of operation. This provides control for the drive, batter pump, blowers and ignition. The drive is by an electric motor through a gear box and chain drive protected by an overload safety clutch. Baking time is adjustable between 1.5 and 3 minutes by means of potentiometer on the control panel, provided suitable batter is used.

Technical specifications

* It may vary depending on the recipe, batter consistency, cream ratio, etc.

** The above details are approximate figures obtained under working conditions and vary according to the thickness of the wafer sheet and consistency of the batter.

*** Because of the low number of baking plates, longer baking times are necessary.
