Embodiment 1

[0014] The invention is a general processing technique of granular feed, which adds an emulsification process after crushing and mixing feed raw materials and before puffing, ripening, drying and granulating. In the emulsification process, add emulsified oil to the component bait powder and / or wetting agent, the total amount added is 15% to 45% of the weight of the bait powder, and then shaped according to the traditional granular bait processing method. The main components of emulsified oil are fat, nonionic surfactant and water. Fats include fin cod liver oil, sardine oil, tallow, lard, soybean oil, rapeseed oil, coconut oil, etc., and one or more of them can be used. Nonionic surfactants include fatty acid sucrose esters, fatty acid esters of glycerin, fatty acid sorbitan esters, fatty acid polyoxyethylene sorbitan esters, fatty acid polyoxyethylene glycerin esters, and the like.

[0015] The added emulsified oil accounts for 15% of the weight of the bait powder, wherein t...

Abstract

The invention relates to a general processing technology of a granular feed. The technology comprises the following steps: crushing and mixing feed raw materials, emulsifying the obtained mixture, puffing the emulsified mixture, slaking the puffed mixture, drying the slaked mixture, and granulating the dried mixture. Emulsified oil is added to a component bait powder and/or a wetting agent in the emulsifying process according to a ratio of the emulsified oil to the bait powder of 15-45:100, and the emulsified oil comprises 5-35wt% of oil, 2-5wt% of a nonionic surfactant and 60-93wt% of water. The use amount of a binder is 1-8% of the weight of the bait powder. A bait made through using the technology has the advantages of good physical properties, moderate viscosity, good sinking property, moderate sedimentation rate and high feeding rate.

Description

technical field [0001] The invention relates to the technical field of feed preparation technology, in particular to a general processing technology for granular feed. Background technique [0002] The processing method of traditional granular feed is generally that the bait powder is mixed with a binder and then sprayed with water to form or the bait powder is sprayed with water dissolved in a binder to form. The disadvantage of this method is that the physical properties of the shaped bait are difficult to control. If the amount of binder is too much, the hardness of the particles will increase, the sedimentation will be too fast during use, and the feeding rate will not be high; if the amount of binder is reduced, the particle size requirement will not be met. Contents of the invention [0003] The purpose of the present invention is to solve the difficult problem of difficult control of the physical properties of feed processing, and to provide a general processing te...
