Steel Alloy Peanut Frying Line

Peanut Frying Line

500kg/hr fried peanut line begins from raw peanut kernels, finished at vacuum packed fried peanut, the line is complete automatic from beginning to end.

Simple Introduction

Simple flow chart: Roasting-cooling-blanching-frying-oil removing-flavor adding -cooling-metal detecting-packing

Roasting: In this line we match an automatic continuous roaster with multi-layers, the hot air is supplied by hot furnace, which burns wood and coal. The raw peanuts will be baked in low temperature (around 120-140 oC), the baking time is about 20-25 minutes, the moisture content will be reduced to suitable degree for following blanching.

Cooling: Due to the function of high pressure air fan, heat and humidity will bring quickly. The peanuts are ready to be blanched and fall to temporary bin.

Blanching: Light roasted peanuts are feed into blanchers, under the rotating and friction of rollers, the red skin will be taken, collected by the air cyclone. The blanched peanuts will fall down to the selecting conveyors.

Sorting: In order to make the blanched peanuts reach to export grade, we often match color sorter to pick out the imperfect peanuts. This sorting job can be done by manual, it depends on customers request.

Frying: In this line we use batch fryers, the temperature will be fixed between 150-165C, frying time is 4-5min.

Oil removing: The two fryers will work alternately, fried peanuts will be dumped into oil removing machine, under the function of centrifugal rotating of drum, the extra oil on peanut surface will leak out via the bottom outlet.

Flavor adding: the deoiling peanuts will be lifted to the flavor added drum, customer can add salt, powder type spices as their ingredients. The spices will be mixed with the fried peanut evenly.

Cooling: the flavor added peanuts will lie down to the mesh stainless steel conveyor for further cooling and ready to be packed.

Metal detecting: for final detecting in order to avoid any metal impurities will content in the fried peanuts.

Packing: In order to extend the shelf time of fried peanuts, most of customer will adopt vacuum package, or they will add deoxidizer in the bag. The package materials often use BOPP/PE compound film.
