Complete production process of extruded nguồn cấp dữ liệu
Before aquatic feed and pet feed ingredients are processed into finished feed products using a feed extruder machine, they undergo seven primary stages: raw material reception and cleaning, grinding, mixing, extruding, drying, coating, and cooling,screening followed by packaging. The following process analysis uses aquatic feed as an example:
Raw Material Receiving and Cleaning
01
Aquatic feed ingredients include fish meal, soybean meal, corn meal, oils, vitamins, minerals, etc. The receiving and cleaning stage primarily removes impurities such as stones, metal, and dust to ensure equipment safety and feed hygiene.
Mài
02
Aquatic feed demands high precision in particle size. This stage employs hammer mills and ultra-fine grinders to pulverize raw materials into fine powder.
Trộn
03
Ingredient blending ensures the feed is fully enriched with all nutrients required for animal diets. This guarantees uniform distribution of each component, preventing nutritional imbalances caused by inadequate nutrient addition or imprecise formulations.
extruding
04
Aquatic feed demands stringent extruding conditions. First, conditioning enhances material cohesion and achieves sterilization. Subsequently, extruders shape the extruded feed, resulting in lighter particles with superior buoyancy.
Sấy khô
05
Expanded feed contains high moisture levels. A hot-air drying system reduces moisture below 10% to ensure feed stability.
Coating
06
Dried feed undergoes oil coating. The oil penetrates through tiny pores in the feed surface, enriching the final product with nutrients and enhancing palatability.
Cooling and Screening
07
The coated feed is cooled in a cooler to room temperature, preventing mold growth and nutrient loss. It is then screened to remove broken particles that do not meet specifications.
Bao bì
08
An automatic weighing and packaging machine seals the feed according to required specifications. Storage requires a dry, well-ventilated, and light-protected environment to prevent mold growth and nutrient degradation.
Các câu hỏi thường gặp
When purchasing feed extruder machines, you may encounter issues across four dimensions: model selection, technical specifications, after-sales support, and cost. The following questions may help address some of your concerns.
1. Which feed extruder machine is suitable for my feed type?
+
Floating fish feed, sinking shrimp feed, pet food, and livestock feed each have distinct requirements for equipment structure and conditioning methods. Confirm whether the equipment supports your target feed type.
2. Is dry or wet feed extruder machine more suitable?
+
This primarily depends on your specific needs. Dry extrusion suits floating feeds and requires lower investment; wet extrusion is ideal for sinking feeds and delivers higher quality, but necessitates a boiler or steam system.
3. Single-screw or twin-screw feed extruder machine?
+
Twin-screw systems are suitable for high formulation complexity, high output, and frequent feed changes; single-screw systems offer lower costs and are suitable for single formulations.
4. What is the pellet diameter range?
+
Different animals require varying pellet sizes, e.g., 0.6-1.2mm for fry, 2-4mm for adult fish.
5. Does the main unit power match my grid conditions?
+
Confirm factory electrical capacity for feed extruder machines rated at 37kW, 75kW, 132kW.
6. Does it support automatic temperature control and variable frequency speed regulation?
+
Precise temperature control and cutter speed regulation directly impact pellet formation quality and stability in water.
7. Does it include post-processing equipment like drying, cooling, or coating systems?
+
Floating feed requires drying and cooling, while sinking feed may only need cooling; coating systems enhance palatability.
8. Does it support multiple raw material ratios?
+
Yes, but high-fat, high-fiber, or high-fishmeal formulations impose special requirements on feed extruder machine screw structure and heating methods.
9. What is the warranty period? Is spare parts supply timely?
+
RICHI extruders carry a 2-year warranty. Lifespan and replacement cycles for wear parts like screws, dies, and cutters must be confirmed in advance. RICHI guarantees lifetime supply.
10. What is the investment budget for a complete fish feed production line?
+
Máy móc RICHI‘s small-scale feed extruder machine lines using dry single-screw extruders typically cost $10,000–40,000 USD. Medium-scale feed extruder machine lines employing wet twin-screw extruders with steam boilers, dryers, coolers, and coating systems generally range from $40,000–90,000 USD. Large-scale feed extruder machine lines feature fully automated high-specification production, typically costing $110,000–210,000 USD.
