Oilseed Crushing Machine Introduction

Oilseed crushing machine is for crushing large oilseeds like soybean, peanut, palm kernel, copra, etc. and pre-pressed oil cakes into small size with uniformity and few powders. Crushing process of oilseeds is vital for improvement of flakes quality and processing capacity of flaking machine, thus oilseeds crusher is the key equipment for oil seeds preprocessing workshop; crushing process for prepressed oil cakes is good for extracting edible oil out in oil solvent extraction or second pressing section.

Types of Oilseed Crushing Machine and Applications

Toothed Roll Crusher

Two rolls are padded with polygonal sawtooth to crush oilseeds by impacting and cutting. This oilseeds crusher is fit for oil cakes and large oilseeds.

Glossy Roll Crusher

There are two types of glossy roll crusher: roll crusher and double-roll crusher. Two rolls move towards each other, and oil material is squeezed by friction between the rolls. Glossy roll crushing machine is suitable for small and medium-size oilseeds with low moisture, such as soybean, peanut kernels, oil tea seeds, etc.

Groove Roll Crusher

There is an inclined slot on the roller surface, and the two rolls rotate toward each other at different speeds. Groove roller crusher can crush oilseeds by squeezing and cutting with high efficiency. It is applied to medium and small size oilseeds, such as soybean, peanut kernel and so on.

Oilseeds Hammer Mill

There are outward hammers on the drum, and when the drum is rotating at a high speed, the cake is crushed by strong impacts of hammers. The hammer mill is with high crushing efficiency, but can generate many powders and has big noise when working.

Features of the Crushing Machine

  1. Easy to operate and maintain conveniently
  2. Energy saving and high efficiency
  3. Stable performance and reasonable structure

Factors Affecting the Crushing Effect of Oil Seeds

  1. Properties of oilseed, like moisture content, temperature, and miscellaneous conditions.
  2. Working conditions of equipment like speed, gap, material feeding volume.
  3. Maintenance of equipment, like sealing of baffles on both sides of tooth roll, wear of tooth roll.

Crushing Requirements of Different Oil Seeds

1. The crushed materials are uniform in size and the granular size should meet requirements.
2. The fewer powder the better crushing result.
3. The crushed material cannot be squeezed out of oil when crushing and can not form lumps.
4. The following are the crushing requirements for common oilseeds in edible oil production:

Oilseed Raw material

Water content(%)

Crushing degree(petal) powder
Through Sieve(mesh/cm) No more than(%)
soybean 10-15 4-8 7.87 10
peanut 7-12 6-8 7.87 5
Pre-pressed cake 8-11 maximum angle line 6-10(mm) __ 8

Different oil seeds and different processing techniques have different requirements for crushing.  If you need, we can provide professional guidance for you to choose proper oilseeds crusher machine.
