How is chicken feed processed? How to process chicken feathers as feed

Taking livestock and poultry feed production as an example, a complete set of feed production lines is used to introduce the introduction of various process equipment and production processes of feed mill production.

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.

Processing of green fodder:

Shredding method The shredding method is the simplest processing method of green feed, which is often used in the processing of green feed for rural chicken households. After the green feed is chopped, it is conducive to the swallowing of chickens and also improves the digestibility.

The green feed for chickens should be cut finely, and the length should generally not exceed 1 cm. Drying method Dried grass and leaves are a kind of supplementary feed widely used by some chicken farms and farm chicken farmers in winter and spring. After crushing and processing, it can be used as raw materials for chicken feed.

It has the characteristics of low cost and large benefits. The harvesting period of green fodder is as follows: grass from heading to flowering, legumes from first flowering to full flowering, and leaves in autumn. Its drying methods can be divided into natural drying and artificial drying.

Carbohydrate feed.

It mainly contains starches and sugars, which can make up less than 70% of the ration mixture. Corn is one of the most energy-rich cereal feeds, accounting for 45% to 70% of the mix. The bran has good palatability, more protein and phosphorus content, and can account for 5% to 30% of the mixture.

Barley contains high crude fiber, and the dosage should not be too much, which can account for 15% to 20% of the mixture. Sorghum has an astringent taste, and too much feeding will make chickens constipated, which can account for about 10% of the mixture. Rice bran is often used as an excipient, and should not exceed 8%.

2. Protein feed.

This type of feed contains 30% 65% protein, which can account for 5% to 30% of the mixture. Soybean cake and peanut cake are good plant protein feed, with good palatability and comprehensive nutrition, which can account for 10% to 20% of the mixture. Because of the toxins in cottonseed cake, the dosage should not be too much, generally not more than 7% of the mixture.

Fishmeal is the highest quality animal protein and can make up 5% to 15% of the mixture. The salt content of the fishmeal should be calculated, and the salt content of the fishmeal used should not exceed that of the mixture.

Summary. Hello dear, I am happy to answer for you, chicken feathers as feed how to process chicken feathers can be directly made into powder.

Hello dear, I am happy to answer for you, chicken feathers as feed how to process chicken feathers can be directly made into powder.

Or the feather seepage is dried and powdered can be added to the diet as feed, but the absorption and digestibility of feather powder is very low, so it can not be added more, and the addition of 3 5% is a more reasonable proportion of the bush file.

How to make chicken feathers directly into powder 1, clean and remove impurities The collected waste chicken feathers are washed with clean water to remove impurities, and sold on the cement site to dry. 2. High-pressure steaming Put the sun-dried waste chicken feathers into the pressure cooker, add 2 dilute hydrochloric acid to the pressure cooker according to the ratio of 5 kg of dilute hydrochloric acid per kilogram of waste chicken feathers, stir evenly, heat, make the pressure in the pot reach kilograms, and keep it for 1 hour, stop the fire and simmer in the pot for 4 hours. 3. Squeeze off the glue When the pressure cooker is opened, when you see that the waste chicken feathers maintain their inherent shape and color, and when they are pulled lightly, take out the chicken feathers and send them to the juicer to squeeze off the glue juice.

4. Rinse the acid The waste chicken feathers that have been squeezed out of the gel juice are repeatedly rinsed in clean water until the acid is rinsed clean, drain the water, and then spread on the cement site to dry. 5. Crushing The sun-dried waste chicken feathers are sent to the pulverizer to be crushed into powder, which is the finished product. 6 In addition, waste chicken feathers can also be processed into feather liquid by:

First wash the chicken feathers in clean water, put them in an iron pot (aluminum pot is not available), add 7 kg of water per kilogram of chicken feathers to boil, then add 45 grams of calcium hydroxide, and boil for 10 15 minutes until the chicken feathers are all dissolved into liquid, which is the finished product. The amount is directly mixed into the feed of livestock and poultry, and when the rough amount is large, it is mixed with the feed and dried for preservation.

The simplest recipe is corn, soybean meal, mineral premix (containing health medicines). However, it is difficult for general manufacturers to adopt high **. If you want to reduce food costs, you can replace corn with cheap bran and low-quality flour, and you can also replace soybean meal with cottonseed meal and rapeseed meal, but keep the energy concentration and crude protein content to a minimum.

If synthetic amino acids are added to the formula to balance the amino acids in the diet, the crude fibre protein will be reduced2 in the formula, thereby reducing the use of more expensive protein feeds such as soybean cake (meal), fishmeal, etc., thereby reducing costs.
