Steam Heating Extruder
- Corn flake steam heating extruder improves starch gelatinization: using steam heating can fully gelatinize the starch in corn, improve the digestibility of starch, make it easier for animals to absorb nutrients, and thus improve the utilization rate of feed.
- Corn flake steam heating extruder preserves nutrients well: Steam heating is relatively gentle, which can better preserve the vitamins, minerals and other nutrients in the corn during the extrusion process, reduce nutrient loss, and make the nutritional value of the feed higher.
- Corn flake steam heating extruder has stable product quality: the steam heating system can accurately control the temperature and pressure to ensure that each batch of corn flakes can be treated stably and consistently during the extrusion process, thus ensuring the stability and consistency of product quality.
- Corn flake steam-heating extruder has strong material adaptability: For corns with different moisture content and varieties, the steam-heating extruder can achieve good extrusion effects by adjusting steam parameters and process conditions, and has strong material adaptability.
- The corn flake steam-heated extruder has a long service life: the steam heating method is relatively mild, causing less wear and tear on the equipment, which helps to extend the service life of the equipment and reduce the cost of equipment maintenance and replacement.
- Safe operation of corn flake steam heating extruder: The steam heating system is usually equipped with complete safety protection devices, such as pressure safety valves, temperature controllers, etc., which can effectively prevent safety accidents caused by improper operation or equipment failure, and ensure the safety of operators and equipment.
How it works
The corn is cooked and softened by steam heat treatment, and the heat and pressure of steam are used to gelatinize the starch in the corn, breaking the hydrogen bonds of the starch. Then, through mechanical action, the rollers of the corn flaking steam extruder process the corn into flakes of specific thickness and bulk density.
Processing technology of corn flake steam extruder
The raw materials are first cleaned of impurities and then soaked to allow water to penetrate into the corn. They are then sent into a vertical stainless steel steamer and heated with 110℃-140℃ steam for 40-60 minutes. They are then rolled with preheated rollers and finally dried and cooled.
Product Specifications of Corn Flake Steam Extruder
The degree of gelatinization is usually adjustable between 65% and 75%, the bulk density is 380-400g/L, and the moisture content of the finished product is adjustable between 13% and 16%.
Corn flake steam extruder equipment material
The parts that come into contact with corn, such as cooking tanks and rollers, are mostly made of stainless steel, which is corrosion-resistant and ensures food hygiene and safety.
Energy consumption of corn flake steam extruder
Taking a corn flaking workshop with an hourly output of 10 tons (daily output of 200 tons) as an example, the total power is about 260kW, and the steam demand is 5-6 tons/saturated steam/pressure 0.8MPa.
Application fields of corn flake steam extruder
It is mainly used for ruminant breeding, such as beef cattle, dairy cows, sheep, etc. It can also be used in horse feed. It is also widely used in chicken feed and pig feed in Europe.
Equipment advantages of corn flake steam extruder
It can improve the digestibility of corn starch, making animals absorb nutrients better; it can kill harmful microorganisms and insect eggs, improving the sanitary quality of feed; it can improve the palatability of feed and increase animal feed intake; gentle steam heating can better preserve nutrients; precise control of temperature and pressure ensures stable product quality.
