How To Choose Peanut Peeling Machine?

About peanut peeling machine, we have roasted peanut peeling machine and wet peanut peeling machine. Today introduced roasted peanut peeling machine. Dry peeling machine peeling rate of not less than 96%; broken rate of not more than 2%; blowing rate of not less than 99%; motor power of 0.96kW; productivity of 500kg / h.

1. Dry peeling machine
The use of two rubber roller reverse rotation to rub peanuts to red peach peanut peeling off. The peeling part is made by a motor, driven by a connecting device such as a belt and a gear, etc. The purge part is composed of a blower and a duct.

 

2. Peeling treatment

The binding force between ripe peanut red peels and peanuts is related to the moisture content of peanuts. When the water reaches a certain value, the binding force to a minimum, this time the peanut by a small force of the role of red skin can peel off from the seed.

Drying off the red is to dry the peanut to a certain extent, the use of glial asynchronous two-roll device will be red peel from the seed kernel, and then according to the difference between the weight of red and seed kernel to separate them.

 

3. Drying test

Peanut stripping is a pre-treatment of peanut processing and comprehensive utilization. In order to ensure product quality, requires drying process does not make protein denaturation, for this drying temperature should not be too high. The study was carried out by oven drying, temperature control at about 60 ℃, drying time of 3h ~ 4h, measured peanut moisture content and peanut peeling rate. Practice shows that the water at 3% to 4%, the peeling rate is high, up to 96%.

 

4. Effect of roller hardness on seedling breaking rate

Peanuts dry after the plasticity is small and easy to crack, therefore, the harder the roll, the higher the seedling break rate. The study began with a pair of rubber hardness of 60 degrees of rubber roller, seed kernel break rate of more than 5%, and then switch to a hardness of 40 degrees of the roller, the crushing rate decreased significantly. This increases the rate of peeling (above 96%) and reduces the rate of breakage (less than 2%).

 

5. Double roller speed selection

Peanuts as long as a small friction by the role of the red will be able to peel off from the seed kernel. So the speed of choice depends on the production capacity and seed kernel break rate (if the speed is too fast, the broken rate increases). The study selected fast roll speed of 490r / min, two roll ratio of 0.33.
