Quality of machine-produced peanut crisps (rempeyek)

A prototype machine for production of peanut crisps (rempeyek), a popular traditional snack of Malaysia, has been developed. The function of the machine was to carry out the filling processes of the slurry and peanuts followed by forming and frying of the peanut crisps. The production capacity of the machine and the product quality were evaluated. Results showed that the machine had a production capacity of 640 pieces of peanut crisps per hour. The end product had a round shape with diameter, weight and thickness of 59 mm, 3 g and 2.5 mm respectively. Acceptability of the product was comparable with traditionally prepared rempeyek especially in terms of texture, taste, aroma, colour and overall acceptability. The prototype machine can be scaled up to any desired capacity by increasing the number of depositors and moulding plates and enlarging the size of the frying tank
