The gauge roller is placed in front of the forming machine and laminator. The pre-made dough flan sent from laminator or three-color dough sheet rolling machine is rolled through rolling unit againto dough sheet with the thickness required for the flan. The rolling speed and conveying speed of each mono machine is controlled separately, so that it can be conveniently and easily operate. They are used in the forming process of hard sweet biscuits and crackers. As for its speciality,they are as followings.
First of all，adopt customized chilled alloy roll of exclusively formula to make rollers of high hardness, making it longer working life. Secondly, roller are designed to be able to make super thin biscuit, by getting dough sheet thickness 0.7mm to 0.8mm evenly.Thirdly, Central Control System provides practical and user-friendly operation function, including upstream follow-up joint- control function which make machine trial running and daily operation easier for operators and as well as saving operators.Fourthly, Menu memory and call out function, easy for next time making same product.Fifthly, Machines can be either control flexibly via touch screen or by buttons.
Sixthly, Roller’s gap distance adjustment adopt electricity motor-driven screw lifting, making it longer working life rather than eccentric wheel and easier operation for workers.Sevenly, Adjustment accuracy:0.01mm. Finally, Gauge roll machine’s drive motor is installed vertically suspended which provide most effective power output  to save energy and easy for cleaning an maintenance.
