Peanut butter processing equipment
PROCESSING: De-stoner---Roaster---Split peanut blancher---first grinding---second grinding---Mixing---cooling---degassing---packing
Roasting: batch nut roaster working temperature 200-220C, roast time 30-40 minutes.
Peeling: Remove the red skin by the frication of two rubber rollers and sucked by the cyclone system. Most of Peanut will be split in half-piece or much small, the bitter germ will be separated by the vibrating sieve at bottom of blancher, finally blanched peanuts will falll to the selecting conveyor.
Primary Grinding: Use Disc grinder to make the first grinding, the blanched peanut will be feed into the primary grinder’s first ,then they will be put by a kind of screw force, peanut will fall to limited gauge between two disc and be grinded by sand disc in high speed. The primary butter will flow to the tank and pumped into the second grinder. The fineness grinding is reach to 60-100mesh. It must able to run 24 hours without stop because of heat.
Second grinding: the purpose of second grinder is for fine grinding. the fineness grinding is reach to 150-160mesh. Water cooling system should be supplied in order to reduce the grinders chamber temperature (both primary and second grinder).its must not over heat, provide sensitive part and easy part to be replace. Time or life spent of part, like seal, cleaning method, assembling method.
Blending : This tank has two layers, with two functions, mixing and Make the butter more homogeneous. Moreover, it can also decrease the butter’s temperature with large extent. this tank must have gauge temperature to measure how hot.
Cooling: The butter is pumped into cooling machine, through pipes twisted inside of cooler, the ideal temperature will obtain. It must have control temperature from cooling Temperature to 45-60C adjustable.
Refrigerator: it’s the key part of the whole plant, the butter’s temperature from second grinder can reach to 90-95C,in order to reduce the temperature of 30C and make it prepared to be packed ,we have to build a cooling system.
The refrigerator work and produce cooling water (water temperature can be set on),cooling water
