Benefits of technology

This patented technology describes an improved way to prevent damage caused when handling food products such as chickens or fishes while they are being shipped over long distances due to excessive temperatures that may cause them' s own body tissue to break down faster. By utilising this new approach, the inventors have developed a special type called Spray Ventilage System that uses compressed gas instead of liquid nitrogen to efficiently circulating cold gases throughout the entire shipment area. It also includes a mechanism to control humidity levels within specific ranges based upon factors like weather conditions. Overall, these systems aimed to provide effective measures against heat stresses associated with transportation processes involving animal carcasses.

Problems solved by technology

This patented technology describes various techniques aimed towards reducing thermal stresses experienced by birds while being shipped or stored outside over winter temperatures. One technique involves mistling warm liquid onto surfaces inside the bird' s chickens through pipes attached to them. Another approach uses atomized coolant instead of regular water but still has limitations like slow cooldown times and limited space availability. Additionally, there have been attempts to combine these two approaches together to improve upon each others outcomes.
