Dog food production equipment
The feed extruder series consists of feeding, extrusion, rotary cutting, heating, transmission, lubrication, and control systems. The feeding, driving, and rotary cutting all adopt variable frequency speed regulation, ensuring stable operation and strong power. Automatic lubrication and forced cooling ensure safe operation. Depending on different raw materials, single or twin-screw feeding systems can be selected for uniform and reliable feeding. The screw is processed with special technology, offering wear resistance, fatigue resistance, and a long service life. Different length-to-diameter ratio structures meet diverse process requirements.
Maintenance points: Replace the grease after 500 hours of bearing operation; regularly lubricate other bearings. Do not strike vulnerable parts such as threaded sleeves with heavy hammers. Raw materials must be cleaned to prevent metal foreign objects from entering. When shutting down for extended periods or changing materials, empty the puffing chamber to prevent clumping, mold, or cross-contamination. Wear parts at the discharge end wear out quickly; when replacing, proceed sequentially from the discharge end and avoid replacing multiple components at once. The machine is easy to operate and clean, and the company provides technical guidance and support.
Characteristics to note in daily operation and maintenance of extruders in pet food production lines, feed extrusion machinery, and fish feed production lines
1. The series of feed extruders mainly consist of a feeding system, an extrusion system, a rotary cutting system, a heating system, a transmission system, a lubrication system, and a control system.
2. The feeding system, drive system, and rotary cutting system of the extrusion equipment all adopt variable frequency speed regulation, with high power and stable operation.
3. Automatic lubrication and forced cooling ensure the safe operation of the extruder.
4. Depending on different raw materials, single-screw or twin-screw feeding systems are selected, providing uniform, stable, and reliable feeding.
5. The screw is processed with special technology, offering wear resistance, fatigue resistance, and a long service life.
6. Different screw length-to-diameter ratio structures can meet the requirements of various processes.

Maintenance and Care of Feed Extrusion Machinery
(1) The box bearings should be lubricated with grease in a timely manner. After 500 hours of operation, all grease should be replaced. (Before initial operation, add an appropriate amount of grease; after 200 hours of operation, replace the lubricating oil.)
(2) Other bearing parts should be regularly lubricated with grease.
(3) During disassembly and assembly, it is strictly prohibited to use heavy hammers or other tools that may damage screws and threaded sleeves. Do not place heavy objects or supports on the extruder.
(4) The raw materials for extrusion should be cleaned to prevent foreign objects such as metal from entering the machine and damaging parts.
(5) Regularly inspect the quality of the feed extrusion machinery and replace worn parts as needed.
Keep the equipment clean.
(1) When the feed extrusion machine is not used for a long time or when changing the extruded material, the material inside the extrusion chamber should be thoroughly cleaned to prevent caking, mold, or cross-contamination between materials.
(2) Since the wear parts near the discharge port wear out relatively quickly, while those near the feed inlet wear less, when replacing wear parts, they should be replaced sequentially starting from the discharge end, and it is not advisable to replace multiple parts at once.
The fish feed production line and pet feed production equipment manufactured by Jinan Datong Machinery Equipment Co., Ltd. are easy to operate and clean. Technical guidance can be provided for the first cleaning, and guidance can also be provided for subsequent cleanings.
