RTB Hygenizers

RTB Hygienizer is a patented solution to thermal treatment of powder feed for hygienic purposes. Before pelleting and after the homogeneous mixing of steam in a conditioner, the raw materials are suspended to balanced heat diffusion for a regular period across a hot and insulated housing named Retention Time Barrel. After the RTB, the product can be treated in a pellet mill, extruder or meal cooler. Consequently, the thermal treatment of the product causes easier operation in the pellet mill, which simultaneously results in graceful pellet quality.

The time period of thermal treatment usually varies between 2.5-4 minutes. RTB hygienizer designed according to “first in first out” principle. Before the pelleting, the RTB hygienizer neutralizes the unwanted microorganisms in the feed. The housing is made of stainless steel. Also, it is wrapped with long-life heat cables which keep the product warm for a long period.
