Method for antioxidant safe processing of feed and high-grease feed prepared with method

Abstract

The invention relates to the field of feed processing and discloses a method for antioxidant safe processing of feed and high-grease feed prepared with the method. The method comprises the steps of 1, matching whey powder, grease and protein to obtain a mixture; 2, adding the mixture to water, adding emulgator, transferring the new mixture into a homogenizer for homogenization, and then transferring the product into an emulsifying machine for emulsification; 3, drying the processed material obtained from the step 2 to obtain the antioxidant high-grease feed. By conducting emulsification after homogenization on raw materials, grease oxidation can be avoided, and storage time can be prolonged; meanwhile, feed production safety is improved. Besides, by the adoption of the method, the adding amount of antioxidant can be reduced, cost can be reduced, and the palatability of the feed can be improved.

Description

technical field

[0001] The invention relates to the field of feed processing, in particular to an anti-oxidation safe processing method of feed and a high-fat feed prepared therefrom. Background technique

[0002] Protein, whey powder, and oil are commonly used nutrient raw materials, and are commonly used raw materials for feed. The preparation methods of these feeds are generally mixed and emulsified first, followed by homogenization, and then spray-dried to obtain powdered feed.

[0003] For example, the Chinese patent with the application number 201310304934.X previously applied by the applicant discloses a method for preparing a powdered oil feed with whey powder. In this invention, whey powder, vegetable protein, animal protein, animal oil, and vegetable oil are mixed in proportion and then added to water. After heating, an emulsifier is added, fully stirred, and then entered into an emulsifier for processing. The emulsified product is passed through a homogeneous Mac...

Examples

Embodiment 1

[0039] Embodiment 1: 150kg whey powder, 500kg soybean protein concentrate, 250kg lard, 150kg soybean oil are added to 2000kg water, the temperature is controlled between 35-100°C, 5kg lecithin is added, stirred, and homogenized finely by a homogenizer. The pressure can be freely adjusted below 400MPa, and then enter the emulsification machine for processing. The rotor speed of the emulsification machine can be freely adjusted below 14000r / min, forming a strong and reciprocating hydraulic force in the reasonably narrow gap between the static grinding plate, moving grinding plate and propeller blades. After the comprehensive effects of shearing, friction, centrifugal extrusion, and liquid flow collision, the semi-finished material is spray-dried through the spray drying tower to become powder, and the dried product is sieved, measured, and packaged.

Embodiment 2

[0040] Embodiment two: 50kg of whey powder, 160kg of coconut oil, 240kg of palm oil, and 450kg of soybean meal are placed in 2000kg of water, the temperature is controlled at about 35-100°C, 10kg of polyethylene ricinoleic acid ester is added, stirred, and passed through The homogenization and refinement of the homogenization machine, the free adjustment of the pressure below 400MPa, and then into the emulsification machine for processing, the rotor speed of the emulsification machine is free adjustment below 14000r / min, forming a strong , reciprocating hydraulic shearing, friction, centrifugal extrusion, liquid flow collision and other comprehensive effects, the semi-finished material is spray-dried through the spray drying tower to become powder, and the dried product is sieved, measured and packaged.

Embodiment 3

[0041] Embodiment three: 150kg whey powder, 195kg coconut oil, 200kg palm oil, 450kg wheat protein are put into the water of 2000kg, temperature is controlled at about 40-99 ℃, adds 5kg bile acid, 5kg sorbitan fatty acid fat, stirs, Through homogenization and refinement, the pressure can be freely adjusted below 400MPa, and then enter the emulsification machine for processing. The rotor speed of the emulsification machine can be freely adjusted below 14000r / min. After forming strong, reciprocating hydraulic shearing, friction, centrifugal extrusion, liquid flow collision and other comprehensive effects, the semi-finished material is spray-dried through the spray drying tower to become powder, and the dried product is sieved, measured, and packaged.
