Quality control is also called quality management. It mainly refers to on-site management within the feed mill. The main purpose is to ensure product quality, improve work efficiency and reduce production costs. Spg China Feed Industry Information Network - based on feed, serving animal husbandry

1. The same formula, why is the quality different? Spg China Feed Industry Information Network - based on feed, serving animal husbandry

A good suckling pig teaches the formula, in addition to the need for good raw materials, but also requires good quality control measures and equipment, processing technology to ensure that good piglet products can be made. Recipe, raw materials, quality control, and equipment processing are closely combined to produce a good teaching and maintenance product.

2, the function of quality control changes Spg China feed industry information network - based on feed, service animal husbandry

With the improvement of the overall quality of feed mill procurement personnel and first-line production workers, the on-site supervision of the quality control department is showing a weakening trend, including Zhengda system has reduced part of the on-site supervision of the quality control department. While the duties of the Quality Control Department are weakened, the quality training for procurement personnel and production frontline employees should be placed in an important position. According to the general requirements of the “Good Manufacturing Safety and Quality Management Regulations”, the quality management of all employees should be implemented. The daily inspection work of the laboratory is fully coordinated with the technical department and the purchasing department to do a good job.

3, teaching materials control points Spg China feed industry information network - based on feed, service animal husbandry

(1) Raw material freshness Spg China feed industry information network - based on feed, service animal husbandry

In terms of raw materials, it is important to ensure the freshness and best stock time of raw materials in order to ensure the raw material freshness, corn starch gelatinization, fish meal freshness, oil acidity and health indicators. Mycotoxins (such as Aspergillus flavus B1, vomiting toxin, gibberellin and ergot toxin), harmful bacteria (such as Salmonella, Escherichia coli) and other important indicators, in line with the requirements for the production of clean feed.

Ring mold quality defects lead to uneven grain size Spg China Feed Industry Information Network - based on feed, service animal husbandry

(2) Process fineness Spg China feed industry information network - based on feed, service animal husbandry

The management of the quality control and processing of suckling pigs should be strictly controlled. For example, some heat-sensitive raw materials are used. In the production process, special attention should be paid to controlling the granulation temperature and quenching time; the temperature and time of quenching and tempering have starch gelatinization. Significant influence, the greater the temperature difference between the granulator inlet powder and the outlet pellet, the higher the gelatinization degree.

The suckling pig pellets can't be made too hard, too hard to seriously affect the palatability. In addition to the feed formula, factors affecting the hardness of the feed pellets include: the pulverization process of the raw materials, the expansion and expansion process of the raw materials, the mixing of raw materials, the addition of water, the fuel injection process, the steam pre-conditioning process, the ring-forming material during the granulation process, and The selection of compression ratio, post-maturing, post-spraying process, drying and cooling process, etc., especially the steam quenching and tempering process, the quenching and tempering effect directly affects the internal structure and appearance quality of the particles. The longer the quenching and tempering time, the higher the starch gelatinization degree, the denser the grain structure and the greater the hardness. Suckling pig feed requires high starch gelatinization but low hardness. Therefore, it is especially important to choose a suitable compression ratio ring mold. Generally speaking, the granulation ring mold compression ratio is 3~5, and the pellets are so Crispy, good palatability, but the powder rate is higher.

In terms of raw material pulverization, after the pulverized corn and soybean are pulverized, the particle size generally has no problem. Other commonly used raw materials are mainly corn and soybean meal. The particle size after pulverization has a great influence on the digestion and absorption of suckling pigs. For suckling pigs, the smaller the crushing size, the lower the diarrhea rate and the higher the digestion and absorption rate. The current research results show that it is suitable to pulverize the particle size from 400 μm to 600 μm from all aspects. If powder is used, attention should be paid to mixing uniformity. The coefficient of variation is not more than 10% according to the requirements of China's compound feed standard, so as to ensure that the feed is fully mixed and the nutrient composition is evenly distributed.
