First, prepare the ingredients of compressed biscuits: 5 kg of puffed powder, 1 kg of sugar, 1 kg of peanut oil, 5 g of salt, 25 g of sesame seeds and 53 g of water. Test the moisture content of puffed powder before batching, so as to master the water quantity, and then adjust the powder.
add oil first and mix well, then add water and mix well. When mixing powder, the temperature should not be too low, otherwise it is easy to agglomerate. The powder temperature is preferably 145 ~ 145℃. After the powder is mixed, the mold is pressed. The size of the mold is 4×8 cm, the height is 7.5 cm, the pressure is 9 kg/cm2, each piece weighs 62.5 g, and every two pieces are packed in a bag, with a standard weight of 125 g. The water content of finished products shall not exceed 6%.
and it should be paid special attention to that: the puffed powder particles should not be too fine. If they are too fine and the temperature is too low, they are easy to agglomerate when mixing powder. The volume of all kinds of grain puffed powder is different, and the pressure should be different when pressing. The pressure should be such that the volume and weight of the product remain unchanged. The variety of oil used should also be selected for better storage.
