With the improvement of people's living standard, broiler breeding industry in the vast rural areas have been greatly popularized and developed, the number of large and medium-sized farms with more than 10,000 in the developed areas of agriculture has been commonplace. Broiler slaughter, and then sent to the Rou Lian Han for slaughtering, division and packaging, the rest of the skeleton is processed into a rich protein, fat and calcium elements of the fine feed, waste to treasure.

recently produced by my company rotary drum dryer after crushing the broiler skeleton drying, the test run results to the user is very satisfied. The skeleton of the chicken was crushed to less than ten mm, and some particles adhered to each other, the moisture content was 60% and the treatment amount was 500kg/h. Drying, the requirements of water content less than 15%, loose particles basically no adhesion phenomenon, the appearance of brown yellow.

Dry Production of rotary drum dryer is a large-scale continuous drying equipment, the complete set of equipment from coal-fired hot air stove, in and out of the material equipment, rotary drum dryer, dust removal system, lifting conveyor system, finished goods warehouse and electronic control system and other institutions. the process parameters of the production line and the selection of the technical parameters and structure of the equipment are based on the careful analysis and production practice of the physical and chemical properties of the material, and a series of original new technology, new technology and equipment are adopted in the design .

In order to make feed non-polluted and maintain the appearance of the original ecological color, drying process using high-temperature flue gas Indirect drying form. The heat source is a chain grate coal-fired furnace with an output power of 48.6 KW. The rotary drum dryer cylinder has an axial inclination of 1.5 degrees and a rotation of 3 r/min. The dwell time of the material in the barrel is about 40-50 min. The hot air inlet temperature is 750 ℃ and the outlet temperature is 165 ℃. Product moisture is 14%, fat 8%, protein 15%, element calcium 19%, the product appearance of brown yellow.

Commissioning site, under the guidance of our technical staff, by the operation of 4 workers, according to operating procedures, turn on the flue gas induction fan, rotary drum dryer drive motor, out of the material twisted cage, feed twisted cage, feeding machine and coal-fired hot air stove. After the temperature reaches the process requirements, the prepared kg wet material in 3 h evenly with the feeder and feed stranded cage to the dryer for drying operations. Rotary Cylinder Dryer hot air import and export set temperature display instrument, and import temperature display instrument and furnace bottom blower interlock, use blower to adjust flue gas output temperature.

Test run results tested, product moisture content 14%, fat 8%, protein 15%, calcium element 19%, yield 4000 kg/8h, the appearance of brown yellow, fully meet the user requirements.
