The 70 wet twin-screw extruder is a large aspect ratio extruder designed and manufactured by Jinan Datong Company by combining the advantages of similar products at home and abroad and the company's various advantages. High output, low energy consumption, energy saving and high efficiency. The machine adopts a large gearbox to change speed, runs very smoothly and has an extremely low failure rate. After the screw is lengthened, the material adaptability is wider. At the same time, because the material remains in the machine cavity for a long time, it can be better matured and mixed. At the same time, the screw speed is accelerated accordingly, which not only improves product quality, but also achieves the purpose of increasing output. Use variable frequency speed regulation to achieve low-speed start and smooth operation. Suitable for all kinds of pet feed, aquatic feed, mink and fox feed, snack food, cereal puffing, abalone feed, etc. It is suitable for a wide range of raw materials and is a multi-functional large-scale puffing processing equipment.
Jinan Datong Extrusion Machinery Equipment Co., Ltd. Twin-screw extruder features:
1. The host adopts advanced frequency converter speed regulation technology to make the equipment more powerful, run more smoothly and save energy;
2. The screw is made of alloy steel and nitrided, so that the screw has a longer life. Some equipment adopts a building block structure, which can be arbitrarily combined according to different needs;
3. Forced lubrication system to ensure longer life of the transmission part of the equipment;
4. Visual fully automatic temperature control system to make temperature control more intuitive and parameters more accurate;
5. The screw has a self-cleaning function, and there is no need to disassemble the screw for cleaning when the machine is shut down;
6. Different screws and aspect ratios can meet different production processes;
7. The main components of the extruder assembly line are the company’s heavy-duty precision processing equipment, with stable quality, low cost and discounted accessories;
8. The company provides: mature formula, equipment process installation and debugging, and after-sales service one-stop service system.
Advantages of Datong Machinery large feed equipment:
(1) All models of host machines can be equipped with an optional computer automatic control system and touch screen operation, which is convenient, simple and safe.
(2) The main machine, feeder and cutting device all adopt frequency conversion speed control, which ensures uniform feeding, strong power and smooth operation.
(3) The main machine gearbox is equipped with a gear oil pump forced cooling and an automatic lubrication system, a twin-screw extrusion pumping mechanism and a double-axis lengthened differential modulator (optional for the wet method main machine) to ensure sufficient maturation of the material and gelatinization of the material. The degree is over 98%.
(4) A wide range of raw materials can be used, and the feed formula can contain more than 12% oil. After adding a double-spiral steam conditioner, the amount of fresh meat added reaches 35%, which satisfies the customer's need to manufacture products with high fresh meat content.
(5) The screw has excellent self-cleaning ability. There is no need to clean the machine bore and screw when restarting the machine or changing material types. The main machine adopts frequency conversion speed control to adapt to different types of raw materials, and the discharging cutter adopts frequency conversion speed control to adjust the length, thickness and shape of the materials.
(6) The screw is made of special high-alloy steel, the wear-resistant sleeve is made of bimetal alloy (the material is optional), and the cavity is made of No. 45 steel with a high-hardness spiral, which is wear-resistant, has a long life, and has a large pressure bearing capacity.
(7) Pet food/aquatic feed is sterilized by high temperature and high pressure during processing, ensuring the hygiene and safety of the feed products.
(8) The cylindrical hole diameter of the discharging die is d=1mm-10mm, and other special shapes of die holes (can be customized according to customer requirements).
(9) Suitable for processing dry pet food pellets, ornamental fish feed/aquaculture puffed feed (floating, sinking, slow-sinking feed). The stability of floating feed in water is more than 24 hours.
