Embodiment 1

[0020] Example 1: The pig hair powder puffing process method of the present invention uses pig hair powder as a raw material, and the pig hair powder is the short hair, broken hair, pig skin scraps and leftovers left after the pig brown hair is removed, and is extruded by extrusion Process method The pig hair powder is extruded.

[0021] Its principle of operation of the extrusion process is as follows:

[0022] The extruder bore of modern extrusion technology can be considered as a relatively special continuous reactor. Feed in the extruder bore, under high temperature and high pressure, undergoes strong extrusion, shearing, friction, mixing and extrusion to gelatinize the starch in the feed and denature the protein, and the components between the materials produce strong The physical and physicochemical changes of the materials have produced great changes in the macroscopic and microscopic structures. At the same time, the feed has high moisture in the extrusion reactor ...

Embodiment 2

[0127] When using:

[0128] 1): Using pig hair as raw material, the pig hair is removed from the pig brown hair, and the remaining short hair, broken hair, pig skin scraps and leftovers are crushed by a crusher with a particle size of 3, 5, 3.5 or 4.5mm ;

[0129] 2): Feed through the feeding device;

[0130] 3): Conditioning through the conditioner, adding steam or adding water for conditioning, when adding steam for conditioning, the amount of steam added is 20%, 30% or 45%, and the working pressure of the boiler is 0.5, 0.6, 0.8 or 0.9 Mpa, the tempering time is 100, 120, 140 or 150s, when adding water for conditioning, the water addition amount is 20%, 30% or 45%, the temperature is 100 or 120°C, and the conditioning time is 100, 120, 140 or 150s;

[0131] 4): Extrusion type puffing technology is adopted. The extrusion type puffing technology uses a single-screw extrusion type puffing system as the processing equipment. The system parameters of the single-screw extrus...

Abstract

The invention discloses a bulking process of a pig hair meal feed, which is mainly applied in the field of bulked drinks. The technical problem to be solved by the invention is to provide the bulking process of the pig hair meal feed having the advantages of stable structure, good quality, easy extrusion and high nutritional value. The bulking process of the pig hair meal feed is characterized by comprising the following process steps of: 1), removing pig palm hair from pig hair serving as a raw material, and crushing short hair, broken hair, pig skin scraps and leftovers with a crusher, wherein the crushing particle size is 3 to 5mm; 2), feeding the crushed material with a feeding device; 3), modifying with a modifer; and 4), adopting extrusion type bulking technology wherein in the extrusion type bulking technology, a single-screw extrusion type bulking system serves as processing equipment.

Description

technical field [0001] The invention relates to an extruding process of feed, in particular to an extruding process of pig hair powder feed. Background technique [0002] To produce a qualified extruded feed, first of all, the selection of feed ingredients, feed ingredients have a great impact on the final product structure, quality, extrusion difficulty, nutritional value, economic benefits and ability to adapt to high levels of fat when needed. big. Therefore, the ability to select raw materials that maintain high-quality standards at the lowest ingredient prices and with the lowest processing costs is a challenge for every technician. Secondly, according to the characteristics of feed raw materials, the selection of appropriate extruding processing technology and the setting of various processing parameters and system parameters during the extruding process play a crucial role in the quality of the output extruded feed product. So far, there is no report on the producti...
