Zheng Chang introduces new innovations for broiler and layer feed equipment and technology
The company has developed new broiler feed and layer feed equipment and technologies throughout its history to improve livestock feed production and enhance animal health safety.

Broiler Feed - Innovations for products
From 1973 when developing China's first-generation particle feed pellet mill to 1990, Zheng Chang used pellet mill with one conditioner to process common particle feed to meet the lower feed requirements of most feed factories in China's feed industry at that time.

In 1998, Zheng Chang introduced the large-scale pellet mills(160-250kW) and technologies from CPM US, and developed the second-generation pellet mill and jacket conditioner, which improved the efficiency of 15-25t broiler feed per single line.

In 2005, Zheng Changinnovated and improved the main transmission structure of the original CPM pellet mill and developed the third-generation pellet mill and differential conditioner, which further improved the capacity.

In 2015-2019, Zhang Chang developed the fifth-generation broiler feed technology and key equipment, creating a leading international level of broiler feed processing technology.

Broiler Feed - Innovations for technologies
The first-/second-generation broiler feed systems: Lower pelleting capacity and feed quality.
The third-/fourth-generation broiler feed systems: Based on the premise of pursuing pelleting capacity, the technologies such as improving the effect of conditioning (equipped with differential conditioner, double-layer conditioner or hygienic conditioner) and increasing the compression ratio of ring die are used to improve particle hardness and reduce pulverization rate.

The fifth-generation broiler feed system: Unlike traditional conditioning technology, it has an innovated intelligent combination of temperature controlling, moisture controlling and smooth gelatinization, etc. Controllable conditioning time(3-10min) and temperature(75- 95℃). Pelleting capacity is increased by 20% compared with the traditional process. Hardness of particles is 4kg, pulverization rate is less than 2%, and formula cost is reduced by 5%.All of the above four key technical indicators can be achieved at the same time, which can benefit feed enterprises and thoroughly solve the problems in the industry.

Layer Feed - Innovations for products
Zheng Chang,like most other feed factories in China, used its first-generationlayer feed technology with the combination of grinding and mixing to producecommonpowder layer feed before 2010.
From 2016 to 2019,the third-generation layer feed coating technology and equipment were developed to produce high-grade, hygienic and sterile particle layer feed.

Layer Feed - Innovations for technologies
Feed produced by the first-generation layer feed technology contained harmful bacteria like Salmonella, E. coli. High segregation, low feed intake, and high feed conversion ratio.

Feed produced by the second-generation layer feed technology achieved certain sterilization effect, but high segregation, low feed intake, and high feed conversion ratio still existed.

The third-generation layer feed coating technology has realized the transformation from powdered feed to particle feed. Less loss of heat sensitive elements such as vitamins, higher feed intake, and lower feed conversion ratio.
