Embodiment 1

[0034] Tangrenshen Group Xuzhou Xiangda Meat Duck Compound Feed 313T was used as the post-injection test object, and the total amount of feed for a single injection was M tons. In order to verify the test effect, the granulation efficiency of the granulator is set at a stable feeding rate of 9 tons to 10 tons per hour. The fan nozzle uses a 303 stainless steel nozzle with a connection size of 1 / 4 inch, model 1 / 4GSS6520; the conical nozzle uses a connection 303 stainless steel nozzle with a size of 1 / 4 inch, model 1 / 4GGSS6.5, the follow-up examples and comparative examples, except for the change of fuel injection volume and fuel injection temperature, other indicators remain unchanged, and the follow-up will not be repeated.

[0035] Specifically include the following steps:

[0036] (1) After the meat and poultry pellets are granulated from the pellet mill, the feed is lifted to the silo by the elevator, and then the first post-injection is performed; the first injection is 5%...

Embodiment 2

[0047] Tangrenshen Group Xuzhou Xiangda Meat Duck Compound Feed 313T was used as the post-spray test object.

[0048] (1) After the granulation of the meat and poultry pellets is completed, the first oil injection is carried out; the first oil injection is 5% M, the oil injection temperature is 75°C, and the number of oil injection nozzles is 4 fan-shaped nozzles, and the nozzles and the feed are arranged at 90°.

[0049] (2) The feed after the first oil injection is put into the auger for stirring. The length of the auger is 5m, and the feed speed in the auger is controlled at 0.5m / s; the internal temperature of the auger is controlled at 75°C.

[0050] (3) After the feed flows out from the auger, the second injection is carried out; the amount of the second injection is 5% M, the number of nozzles is 4 conical nozzles, the nozzles and the feed are arranged at 135°, and the injection temperature is 75°C .

Embodiment 3

[0056] Tangrenshen Group Xuzhou Xiangda Meat Duck Compound Feed 313T was used as the post-spray test object.

[0057] (1) After the granulation of meat and poultry pellets is completed, the first post-injection is carried out; the first injection volume is 5% M, the injection temperature is 85°C, the number of nozzles is 4 fan-shaped nozzles, and the nozzles and feed are arranged at 90°.

[0058] (2) The feed after the first oil injection is put into the auger for stirring. The length of the auger is 5m, and the forward speed of the feed in the auger is controlled at 1.0m / s; the internal temperature of the auger is controlled at 70°C.

[0059] (3) After the feed flows out from the auger, the second oil injection is carried out; the amount of the second injection is 5% M, the number of nozzles is 4 fan-shaped nozzles, the nozzles and the feed are arranged at 90°, and the injection temperature is 85°C.

Abstract

The invention provides a preparation method of high-efficiency post-oil spraying technology for poultry feed, comprising the following steps: (1) performing the first post-oil injection after the meat and poultry feed is granulated; (2) feeding the feed after the first oil injection into the auger For stirring, the auger uses a frequency conversion motor to control the forward speed of the feed; the outer layer of the auger uses a steam jacket to keep warm, and uses a temperature sensor to control the internal temperature of the auger; (3) After the feed flows out of the auger, the second post-spray is performed. The invention cleverly solves the contradictory relationship between the amount of fuel injection and the uniformity of fuel injection by adopting the secondary post-injection process. At the same time, the whole production process uses a steam jacket to keep warm throughout the whole process, effectively avoiding the problem of feed surface temperature and spray in winter. The oil temperature difference is too large, and the agglomeration problem caused by the instant condensation of oil. Moreover, when the fuel injection amount of the granular feed prepared by the method reaches 15%, the fuel injection of the feed can still be uniform, and the product is not agglomerated, which can effectively improve the growth performance of meat poultry and improve the economic benefits of breeding.

Description

technical field [0001] The invention relates to the technical field of feed production and processing, in particular to a preparation method of poultry feed with high-efficiency post-oil spraying process. Background technique [0002] With the vigorous development of my country's meat and poultry breeding industry, the energy demand for meat and poultry feed is getting higher and higher, and oil is currently the best choice to provide energy for meat and poultry. In the existing meat and poultry feed, the fat content is generally about 5%. Considering the production cost and energy efficiency conversion, most of the animal fats that are easy to solidify and agglomerate, such as lard and duck fat, are the main fat sources. [0003] In the actual production process, due to the limitation of the design requirements of the granulator process, the amount of oil added to the mixer will not exceed 3%, otherwise it will easily cause machine blockage during the production process. In...
