Introduction to the production equipment and production process of the feed mill

According to the physiological characteristics, nutritional needs and raw material characteristics of livestock and poultry (pig feed), combined with engineering construction and production practice experience, we will provide you with excellent production technology and engineering design services.

Specialized production technology ensures the freshness of raw materials and the efficient balance of nutrition; High-performance equipment and accessories to reduce operating costs, reduce carryover and avoid cross-contamination; Excellent control technology realizes the automation, intelligence and traceability of production to ensure feed safety. The storage design of raw materials, the automatic warehousing of bagged raw materials, the automatic design of the small material system, the automatic control of stand-alone equipment, the use of automatic packaging and palletizing devices have reduced the use of labor.

Raw material. Raw materials are the source of feed production. Mainly: corn, wheat bran, secondary meal, fish meal, cake meal after oil extraction of various oil crops (such as soybean meal, rapeseed meal, etc.). All food processing by-products can be used as feed.

Clean. Bulk grains received from farms typically include grain by-products and impurities such as straw, stones, metal, paper, wood chips, small animal carcasses, and powder. The cleaning operation is to remove these impurities with equipment and systems such as magnets, screens, dust collectors, etc., to ensure that the stored grain is of good quality and to protect the machine during the subsequent processing steps.

Smash. Crushing is an operation to reduce the particle size of the feed and increase its specific surface area, which can enhance the digestion capacity of the animal, improve the utilization rate of the feed, and also improve the processing quality and work efficiency of the subsequent process steps such as batching, mixing, and pelleting.

Ingredient. The batching and mixing process refers to the combination of bulk dry raw materials and liquid raw materials into a homogeneous mixture with added value.

Mix. <>

Molasses added. Refers to the scale-up, addition and mixing of dry and/or liquid trace elements and premixes to form a complete feed mixture, i.e. a formulated diet.

Granulation. Extrusion refers to the process by which moist, expandable starch or protein material is plasticized in a tube by a combination of moisture, pressure, heat, and machinery. This results in an increase in the temperature of the product inside the tube, gelatinization of the starch components, denaturation of the proteins, stretching or recombination of the tactile components, and exothermic expansion of the extruds.

In the submersible feed process, the treated feed pellets enter the pelleting equipment and are compressed into pellets by means of rollers and dies in the pelleting chamber.

Cooling. In the feed pelleting process, the cooling of the feed pellets is essential. When leaving the pellet mill, the feed pellets are very hot, soft and rich in moisture, and the cooling process cools them to just over room temperature of 3 - 5 and reduces their moisture content to safe standards for easy transport and storage.

Screening. After cooling and drying, the whole pellet or extrudate is sieved to remove fines and spills so that the pellets reach a qualified size.

Wrap. The packaging operation starts from the finished feed enters the ** box above the packager and ends when the bagged feed is placed in the warehouse. The procedure includes weighing each bag of feed, placing the weighed items in the bag, closing the bag mouth, labeling the bag, coding the bag, palletizing the bag, and moving the bag to the warehouse for storage.

Fodder.

First of all, the equipment is introduced, there are several major mechanical equipment such as elevators, pulverizers, mixers, batching scales, granulators, coolers, balers, etc., there are many small points in it, but it can not be said in detail, the production process is that the raw materials are transferred from the underground silo through the auger to the pulverizer for crushing, and then after the elevator is lifted and then mixed with various raw materials in the mixer, after mixing (there are two processes of mixing first, then crushing and first crushing in the mixing) to the batching system, mixed according to a certain proportion and then granulated by the granulator, and then cooled by the cooler, Finally, the finished product is weighed and packed.

There is a lot of information on feed processing methods in the China Animal Lu Jing Mu Manuscript Sen Street Forum.
