In recent years, the demand for zongzi in the national market has increased by 35% every year, but the production of zongzi is almost purely manual, with backward production methods and low efficiency, and food hygiene and safety cannot keep up with the development needs of the times. The scale production level of Zongzi industry with glutinous rice, red beans, pork and other agricultural products as the main raw materials is low, and the development speed of Zongzi industry is slow due to the shortage of skilled labor (such as the need to train a skilled Zongzi wrapping worker 1 year). Since 2006, "Real Old Man" has taken scientific and technological innovation as an important work content of enterprise development and devoted himself to changing the way of pure manual production. At the beginning of 2007, the first mechanized assembly line in the history of zongzi industry was successfully developed-automatic filling assembly line for dumplings. The success of the automatic filling line for dumplings has changed the defects of traditional manual cleaning of dumplings, such as difficulty, low work efficiency, poor consistency, easy cross-contamination and high proficiency requirements. The experimental data show that after the automatic filling line of zongzi is put into use, the average skilled worker can pack 280 zongzi from the original 200 packages per hour, and the labor efficiency is improved by nearly 40%. At the same time, the stability of product quality is ensured, the weight and size of zongzi are consistent, and the position of stuffing in the middle of zongzi is accurate, which makes zongzi taste better. At present, the project has obtained a national patent.

In order to further realize the automation of zongzi wrapping, Zhen Zhen Lao Lao developed an automatic zongzi wrapping machine, which replaced the manual winding process with machinery. The successful development of this project will improve the efficiency of zongzi package by 200%, which will have a far-reaching impact on the whole zongzi industry.

In 2007, the government issued special food recall regulations, which put forward new requirements for the food industry. "Pearl Krabs Lao" has strengthened control in food hygiene management, reformed various facilities and trained employees in quality and professional knowledge, so as to improve the hygiene concept of all employees and implement the policy of quality first.

"Grandma Pearl Krabs" brand has successively won famous trademarks in Nanhu District, Nanhu District and Jiaxing City. "True Old" Zongzi was named "China Famous Snack", and won the gold medal of previous China Zongzi Culture Festival and the quality product award of Jiaxing Agricultural Products Fair in 2008.
