We have successfully processed oats for multiple customers, for many years now. Our machines have decreased the roasting time traditionally expected by our customers, and astonished them with excellent time saving and efficiency! One of our customers was convinced that it needs 40 minutes, but found it was successfully roasted in 8 minutes! A great increase to his expected capacity. Some perspective about oats processing: Raw, un-hulled oats have lipase enzymes that get released when the seeds are damaged or handled aggressively. When this enzyme is released, the oats develop a bitter taste over time. The bitter taste intensifies over time. It is thus very important to handle the oats carefully and do the de-hulling just prior to further processing. We recommend that clients do not store the de-hulled oats for too long before it is processed. Oats lipase enzymes are particularly stubborn and have to be in-activated properly during processing, otherwise you will have product shelf life problems and possible claims from your clients. These enzymes have to be in-activated by a combination of steam and heat treatment, over a certain time period.

We start with clean, de-hulled oats (groats).

The groats are then exposed to live steam, which is condensing onto the whole surface area of the groat particles.

(Condensing steam is the highest heat transfer medium available in food processing.)

Two things happens to the groat particle:

The temperature rise from 10 ᵒC to 98 ᵒC in a few seconds, and the moisture content increase due to the steam that has condensed onto it.

Then the groats should be kept in this condition, to kill the enzymes.

This is done in the steeper bin.

After the steeping process, the groats goes into the roaster where it is exposed to a higher temperature.

The roaster removes some of the moisture that has been added by the steam process and

also assist in killing the enzymes.

Leaving the roaster, the groats should have about 10-12% moisture content.

Lower moisture content causes more fines production during flaking.

The hot oats is passed through a roller – flaker, and is then cooled and goes to the storage bin.

Roastech also has multiple peanut processing customers, for many successful years now. Groundnuts or Peanuts can be roasted to perfection in the Roastech Roaster due to the variable speed drive options and temperature setting options. Darker roasting is required for a more intense flavor when making peanut butter whilst a lighter color is preferred when preparing cocktail peanuts. All of this is possible with our Roastech roaster. Many commercial businesses have full peanut roasting and processing lines, but also in particular, our very special Project Peanut Butter! They welcome any inquiries and Zoom videos. They have helped over a million malnourished children and mothers get healthy and strong again!!
