Mobile Processing Trailer Specifications

Basic 36 ft Trailer

Primary Activity:

On farm USDA inspected slaughter of livestock and transport of dressed carcasses to fixed facility for chilling and subsequent processing.  Skinning and evisceration will take place inside the unit and dressed carcasses are then hung in a refrigerated section of the unit.

General Information:

The trailer is divided into three sections, mechanical/storage, hanging carcass cooler, and processing from front to rear. The design of the unit takes into consideration the need for robust construction while minimizing weight and USDA requirements for fit and finish of materials, which allow for sanitary operations and cleanup. The cooler and processing sections are wet areas and all materials and electrical fittings are rated for use in wet environments.
