Abstract

The invention discloses an extruded guar meal and a preparation technology and application thereof and relates to the technical field of feed processing. The preparation technology comprises the following steps of: S1, carrying out impurity removing and screening on guar meal according to production requirements, putting the guar meal into a conditioner for conditioning moisture and temperature until the moisture of the guar meal reaches 20-25% and the temperature reaches 80-90 DEG C; S2 putting the conditioned guar meal into a twin-screw extruder or a single-screw extruder for extruding; andS3, drying the guar meal extruded in the step S2 to obtain extruded guar meal with the moisture content of 9-13%. By adopting a wet extrusion technology, the preparation technology disclosed by the invention has the advantages that the ripening effect is good, beneficial nutrients are kept complete and the antinutritional factor passivation effect is good; the nutrient absorption rate of the guarmeal is increased; and the extruded guar meal has the characteristics of low cost, less pollution, low energy consumption, high production efficiency, high yield and the like and can be widely appliedto feeds for animals, such as livestock, poultry and fish.

Description

technical field [0001] The invention relates to the technical field of feed processing, in particular to puffed guar soybean meal and its preparation process and application. Background technique [0002] Protein feed is one of the important raw materials necessary for the development of animal husbandry. At present, there is a lack of high-quality plant-based protein source feed in my country, and soybean meal is mainly used as the main raw material. However, the price of soybean meal is severely controlled by foreign countries, and the price is too high. Negative Effects. At present, in addition to India, Pakistan, Iran and other countries using guar soybean meal as protein feed, my country is also actively introducing guar beans. [0003] Guar meal is a by-product of extracting guar gum from guar beans at 60°C-70°C. It is very rich in nutrients. As shown in Table 1 below, its crude protein and amino acid levels are basically the same as Soybean meal is equivalent, and g...
