Wet extrusion feed machinery equipment
The large aspect ratio extrusion equipment of the 70 wet-type twin-screw extruder adopts a large gearbox and variable frequency speed regulation technology, ensuring stable operation, energy saving, and high efficiency.The screw is made of alloy steel with nitriding treatment, offering long wear life and self-cleaning function, allowing material change and cleaning without disassembly.The extended screw ensures more thorough material cooking, with a gelatinization degree of over 98%, suitable for various raw materials such as pet feed, aquatic feed, mink and fox feed, and snack foods. The feed formula can contain over 12% fat, and with the twin-screw conditioner, the fresh meat addition can reach up to 35%.The discharge mold aperture of 1-10mm and special shapes can be customized, with the finished product maintaining stability in water for over 24 hours.The whole machine is equipped with a forced lubrication and fully automatic temperature control system, paired with the company's formula, installation, commissioning, and after-sales one-stop service, making it an ideal equipment for large-scale extrusion processing.
The 70 wet-type twin-screw extruder is a large aspect ratio extruder designed and manufactured by Jinan Datong Company, combining the advantages of similar domestic and international products with the company's multiple strengths.High output, low energy consumption, energy-saving and efficient. This machine adopts a large gearbox for speed change, operates very smoothly, and has an extremely low failure rate.After the screw is extended, the material adaptability becomes broader. At the same time, due to the longer retention time of the material in the machine cavity, it can be better cooked and mixed. Meanwhile, the screw speed is correspondingly increased, achieving the goal of improving product quality while increasing output.Using variable frequency speed regulation to achieve smooth low-speed start and operation.Suitable for various pet feeds, aquatic feeds, mink and fox feeds, leisure foods, grain puffs, abalone feeds, etc.The raw material has wide adaptability and is a multifunctional large-scale puffing processing equipment.
Jinan Datong Puffed Food Machinery Co., Ltd. Twin-Screw Extruder Features:
1. The main drive adopts advanced inverter speed control technology, providing strong power and smoother, more energy-efficient operation.
2. The screw is made of alloy steel with nitriding treatment for longer life; certain models use modular assembly structures that can be freely combined according to different needs.
3. A forced lubrication system ensures a longer service life for the transmission parts of the equipment.
4. A visible fully automatic temperature control system makes temperature adjustment more intuitive and parameters more precise.
5. The screw has a self-cleaning function, eliminating the need to disassemble and clean it when stopping.
6. Different screws and length-to-diameter ratios are available to meet various requirements.
7. Main components of the extruder production line, company's heavy equipment precision machining equipment, stable quality, low cost, and favorable accessories;
8. The company provides: mature formulas, equipment process installation and commissioning, and a one-stop after-sales service system.
Advantages of Datong Machinery's large-scale feed equipment:
(1) All models of the main machine can be equipped with a computer automatic control system, with touch screen operation, convenient, simple, and safe.
(2) The main machine, feeder, and cutting device are all controlled by variable frequency speed regulation, ensuring uniform feeding, strong power, and stable operation.
(3) The main machine gearbox is equipped with a forced cooling gear oil pump and an automatic lubrication system, a twin-screw extrusion pumping mechanism, and a dual-shaft extended differential conditioner (optional for wet-type main machine), ensuring thorough material gelatinization with a gelatinization degree of over 98%.
(4) A wide variety of raw materials can be used, and the feed formula can contain over 12% oil. After adding a twin-screw steam conditioner, the amount of fresh meat added reaches 35%, meeting customers' needs for high fresh meat content products.
(5) The screw has excellent self-cleaning ability. There is no need to clean the barrel and screw when restarting the machine or changing material types. The main machine adopts variable frequency speed control to adapt to different raw materials, and the discharge cutter adopts variable frequency speed control to adjust the length, thickness, and shape of the material.
(6) The screw is made of special high-alloy steel, the wear-resistant sleeve is made of bimetallic alloy (material can be customized), and the cavity is made of 45# steel, used in conjunction with a high-hardness screw, offering wear resistance, long service life, and high pressure-bearing capacity.
(7) Pet food/aquatic feed undergoes high-temperature and high-pressure sterilization during processing, ensuring the hygiene and safety of the feed product.
(8) The discharge die has cylindrical apertures with diameters ranging from 1mm to 10mm, as well as other special-shaped die holes (customizable according to customer requirements).
(9) Suitable for processing pet food pellets, ornamental fish feed/aquaculture extruded feed (floating, sinking, slow-sinking types), where the floating feed maintains stability in water for over 24 hours.
