Defrosting of butter

This company defrosts large quantities of butter with a process lasting up to 6 days. See how we helped them to speed up their process with our fast defrosting solutions.

Former process

This company, located in Saudi Arabia, needed a solution to defrost thousands of tons of butter per month before individual packing … Usually, they used a tempering room to thaw the blocks of butter.


However, this defrosting method could take up 5 to 6 days, utilizing a lot of space, energy, and limiting production flexibility.

Customer needs

The customer needed to defrost 25 kg butter blocks, from -18 °C to +5 °C / +10 °C. The capacity requested was about 1500 to 2000 kg per hour.


The main goal was to move from a 6 day process to a solution taking only minutes. The equipment would need to work in shifts of 8 hours, depending on production.

Solution proposed

To help the customer save precious time and gain productivity and flexibility, SAIREM recommended a continuous microwave tempering solution, the TMW75 tunnel.


This equipment greatly accelerates the defrosting process, while preserving all the organoleptic properties of the product being treated.

Key benefits

  • Speed: thanks to the microwave technology the company reduced the defrosting time of its products from 5/6 days to less than 10 minutes.
  • Flexibility: the customer is now able to meet requests for last minute orders.
