Cao Yaoling: A brief description of the pretreatment process of raw materials in the teaching material

September 06, 2020

The teaching material is the first kind of feed for suckling pigs. From liquid breast milk to solid food, how to make suckling pigs eat as soon as possible is an important factor in formulating and producing teaching materials. In addition to the formulation, the quality of raw materials, production management, etc. are all aspects that need to be considered. The production process accounts for a relatively large proportion, especially the pretreatment process of raw materials in the teaching materials. The following is a brief explanation: tJs China Feed Industry Information Network - based on feed, serving animal husbandry

1 puffing process tJs China feed industry information network - based on feed, service animal husbandry

Corn is the most commonly used raw material for pig feed. The quality of the corn used in the feed is higher than the quality of the corn in other stages. Puffed corn is a form of corn that is often added to the trough. The puffing process is divided into wet puffing and dry puffing. Wet puffing refers to the process of producing fluffy materials by steam pre-tempering, extrusion, puffing, shearing, etc., while dry puffing The biggest difference is that no steam conditioning process is required. It is not correct to distinguish whether it is wet or dry by adding water during the expansion process. The difference between the two is steam. For corn, both dry and wet puffing can make the puffed corn have a sweet taste and promote the feeding of suckling pigs. However, comprehensive consideration, dry expansion is better than wet expansion, mainly because (1) dry bulk of corn bulk density of 160-180g / L, gelatinization degree can reach more than 95%, quality is stable; (2) dry method The temperature of puffing is higher, the shearing and protein denaturation of starch are more thorough, and the suckling pig is easier to digest and absorb; (3) the dry puffed corn has lower moisture content and is conducive to preservation; (4) there is no steam in dry puffing. Therefore, there is no need for a boiler and the energy consumption is low. tJs China Feed Industry Information Network - based on feed, serving animal husbandry

2 micro-powder process tJs China feed industry information network - based on feed, service animal husbandry

The suckling pig's mouth is delicate, and the hard feed affects the feeding of the suckling pig. Therefore, in the production, the large-grain raw material must be crushed before it can be used to prepare the teaching material. Smashing is a process in which a raw material is struck and broken into granules or powder by a hammer type or a roll mill. The pulverization process is divided into ordinary pulverization, fine powder and fine powder. Different pulverization sizes can be selected according to different animal feeding stages. For suckling pigs, micro powder is the first choice. The micropowder here refers to a powdery substance having a raw material pulverized particle size of 80 mesh or more. Among the raw materials used in the suckling pig feed, corn and soybean meal are large granules or flake-shaped raw materials, and micropowder is required, and the purpose of the micropowder is to make The nutrients in the raw materials have the largest contact area with the enzyme preparations in the intestinal tract of the animal, thereby improving the digestion and utilization rate of the raw materials. In addition, from the feeding characteristics of suckling pigs, the finer the raw materials, the more the suckling pigs like to eat. In addition, there are other large-sized raw materials in the formulation, which can be used to make a fine powder and require a 60 mesh screen. Only in this way can we make a product with even particles. tJs China Feed Industry Information Network - based on feed, serving animal husbandry

3 emulsification process tJs China feed industry information network - based on feed, service animal husbandry

For pig farms, adding liquid grease to the formulation is a headache, as additional grease addition equipment is required and the cleaning process of the production line is cumbersome. Oil powder just happens to solve this problem. Commonly used raw materials for producing oil powder are coconut oil, palm oil, fish oil, soybean oil, animal fat, etc. Phospholipid oil is generally used as an emulsifier. Coconut oil, palm oil, and animal fats contain more saturated fatty acids, while fish oil and soybean oil contain more unsaturated fatty acids. Different fats and oils can be selected according to the different feeding stages of pigs and the types of fatty acids contained in feed ingredients. Formulated in a certain ratio to meet the pig's need for fat. The oil powder production process is the process of homogenizing and emulsifying oil. Some kinds of oils, such as coconut oil and animal fats, have lower freezing points. When the weather is cold, they tend to agglomerate. They must be heated and melted before use. Different oils and fats According to the formula content, the ingredients are mixed by the automatic batching scale, and the adsorption carrier is uniformly mixed. In order to prevent the mixing and agglomeration phenomenon, the mixing and pulverization and remixing process are carried out to ensure the uniform distribution of the oil in the carrier. tJs China Feed Industry Information Network - based on feed, serving animal husbandry

4 package process tJs China feed industry information network - based on feed, service animal husbandry

Palatability is the key to determining whether a suckling pig is eating. The suckling pig prefers sweetness and is sensitive to bitterness. Even in large pigs, bitterness is unwelcome. For mineral elements with a small proportion of added, it will react with vitamins, and chemical reactions will also occur between different mineral elements, thus reducing the raw material potency. For example, choline is a relatively active vitamin that often destroys the structure of other substances and reduces the value of use. So we can use the coating process for raw material processing. The key to the coating process is the packaging material. The suitable packaging material can separate the different molecules of the raw materials, reduce the chance of reaction between each other, ensure the content of the product to the greatest extent, and reduce the amount of coated raw materials to save the formula. cost. tJs China Feed Industry Information Network - based on feed, serving animal husbandry
