Recent health guidelines prohibit the use of colloid mills, waste coolers can be an ideal alternative. Restaurant owners must have a separate refrigerated room for storing waste. A waste cooler is a device used to store all the organic waste generated in the kitchen. The waste must be refrigerated and kept under refrigeration conditions until its final use in order to stop the process of bacterial growth, and thus prevents their decomposition, the release of unpleasant odors. Waste refrigeration equipment is required to maintain proper hygiene.
