Different Types of Food Processing Machines and How They Work


Food crusher

There are a lot of machines that go into preparing our food. When you think of machines involved with food production, some of the most important are crumblers, tumbling drums, and vibratory screeners.


Crumblers, sometimes also known as crackers, are used as part of the process for flour milling, processing oilseed, and crumbling feed pellets. Crumblers are a great cost-effective solution for grinding and milling. Crumblers are especially good at pellet production, using rollers to crush pellets to different sizes depending on need.


Tumbling can be done both wet and dry in a machine using a tumbling drum of varying diameter. The diameter is usually smaller than the length, and the barrel speeds vary from 20 to 38RPM. Tumbling separates one part from all others and can take from 6 hours to 24. The barrel is usually loaded carefully, to no more than 50% of the height, in order to allow freedom of movement.

Food Crusher

Rotary crushers are able to create enormous force. They are designed both for food processing, but also for recycling purposes. Their shaft impactors do the key work, and they can be calibrated for the size reduction desired. Most can be calibrated between 10:1 and 25:1 ratios. Their speed can be as slow as 85 rpm to a typical high of 1,200 rpm. The newest types have different sets of hammers within them, allowing them to work on different materials.

Vibratory Screeners

Screening can also be done either wet or dry. The screens separate materials into two flows according to size. The separated materials then go on to be further processed. The screen itself is on a fixed frame and a drive vibrates the cloth on the screen at a high frequency. Particles from 3mm down to the size of +150 mesh can be processed using these screens.

Extruding Machines

These machines are able to adjust a product by adding fillings or creating interesting shapes. There are the single screw and twin screw machines, and modern machines can extrude the second product onto a first simultaneously.


Mixing is such an important part of any food production that there are many types of mixers available in every conceivable size. There are aerators (whippers), agitators, dough mixers, homogenizers, meat mixers, powder mixers, ribbon mixers, viscous product mixers and many more. These are used through all sector of food production and at every level.

Food processing equipment is essential to keeping our shelves stocked with quality food at affordable prices. From crumblers to the crusher, you always need the right machine for the right job.
