The invention relates to a technology for the production of peanut coated food by variable-temperature pressure-difference puffing technology, which comprises the following steps of: acceptance check, pick-out, baking, cooling, peel-off,
coating, oven
drying, puffing
drying, cooling, pick-out of edible material,
metal detection, weighing and packaging, box sealing and warehousing of the finished product, wherein the ingredients in the process of
coating and the weight parts thereof are as below: 20-50% of peanut kerbel, 10-30% of flour, 10-30% of
modified starch, 0-10% of
rice flour, 0-15 of white
crystal sugar and flavoring additives as the balance; the puffing
drying process is as below: the coated and dried peanuts are put in an puffing tank which is heated up to the puffing temperature of 60 to 120 DEG C, evacuation is performed at the temperature of 70 to 100 DEG C for 120 to 210 minutes after standstill for 5 to 20 minutes; and the puffing
pressure difference is 0.2 to 0.5MPa. The peanut coated food produced according to the technology of the invention is rich in
nutrition, convenient for
digestion and absorption by
human body, long in storage period, less in
nutrient loss, good in crispness, low in
hardness and excellent in taste, thus the peanut coated food meets the demand of massive consumers and includes wide market prospect.
