In 2003, the new baking machine and cooling machine were successfully trial produced at Qiaqia Food Co., Ltd;

In 2004, the three-layer dual side hot air circulation mesh belt dryer was successfully tested in Shandong Sandy Soil Food Co., Ltd; The three-layer dual side hot air circulation mesh belt dryer, due to its unique structural design, saves more than 40% of electricity compared to the previous year. It has the advantages of small footprint, energy saving, uniform drying, and a crispy and fragrant taste;

In 2005, the fully automatic continuous melon seed automatic frying pan, which had been developed for many years, was successfully tested in Qiaqia, Anhui. Its appearance completely ended the history of manual and semi mechanical frying in the frying industry, promoting the rapid development of the entire industry;

In 2005, our factory designed and produced a large automatic frying pan - a heat transfer oil type automatic frying pan for melon seeds (peanuts). It was successfully tested in Qiaqia, Anhui in the same year, and the automatic continuous frying was carried out. Large yield, wide range of frying time, low temperature slow frying makes the quality and taste of nuts more crispy and fragrant than high temperature frying, effectively extending the shelf life of finished nuts;

The natural gas automatic frying pan developed and produced in 2007 can be produced in a double layer stacked continuous mode, designed for nuts that require long-term frying. It was successfully tested in Qiaqia, Anhui in the same year;

In 2009, the direct fired nut automatic frying pan (patented product) increased production by 20%, reduced energy consumption by 20%, and had a more crispy and fragrant taste due to the unique combustion mode and material circulation mode of the equipment;

The successful development of a fully automatic dipping machine (patented product) in 2010 completely changed the history of manual and semi-automatic dipping water in the frying industry, truly achieving streamlined production from ripening to packaging;

In 2011, the production line for stir frying melon seeds (nuts) with thermal oil and natural gas (patented product) changed the production of nuts that require long-term frying, such as peeled melon seeds, watermelon seeds, peeled pumpkin seeds, apricot kernels, and wheat, from intermittent production to continuous production. This effectively saves labor, achieves energy conservation, and is easy to operate during the frying process;

In 2011, the multi-layer mesh belt dryer was successfully developed (patented product). The design of the multi-layer mesh belt and the unique hot air circulation method enable the material to be heated up, down, left, and right simultaneously, resulting in a more uniform drying and crispy taste; Energy consumption has decreased by 20% year-on-year and electricity consumption has been saved by 40%. It is widely used in the national frying industry and has received widespread praise;

In 2012, the spiral reflux automatic frying pan was successfully developed (patented product), effectively solving the fatal defects of the double tube heat transfer oil frying pan. The operation and maintenance were simpler, and the yield increased by 20% compared to the same period last year. It effectively saved energy and reduced consumption, and the fried nuts had a crispy and fragrant taste. Currently, it has been widely praised by many manufacturers for its use;

In 2013, the direct fired fryer was improved to reduce combustion costs by 20%, achieving high energy consumption and low energy consumption for the same production;

In 2014, he wrote the industry standards for nut food drying equipment and nut food frying equipment of the Ministry of Light Industry of China;

In 2014, the natural gas direct combustion dual side hot air circulation belt dryer was used for direct combustion heating of natural gas, resulting in pure exhaust emissions. The natural gas utilization rate was close to 100%, energy-saving, fast heating, and precise temperature control. The thermal energy consumption has been effectively reduced by 25% year-on-year, and the energy consumption is lower than that of similar equipment both domestically and internationally; 30% -40% higher production than similar products;

In 2015, the intermittent hot air circulation dryer saved 30% -40% energy compared to ordinary intermittent dryers;

In 2016, we successfully developed a natural gas direct combustion hot air dual circulation belt dryer, which has dual sided and bidirectional hot air circulation, zone temperature control, wide range of temperature and drying time adjustment, simple regulation, and multiple uses for one machine;

In 2016, we successfully developed a fully automated nut production line, enabling automated and continuous production of tree nut drying;

In 2017, a multifunctional belt dryer (patented product) was successfully developed, which can switch between dynamic and static drying modes according to different drying materials, suitable for drying any material.

In 2018, we successfully developed a nut direct fired automatic fryer and a daily nut production line, mainly used for nut frying and daily nut flavor and drying.

In 2018, it was awarded the title of High tech Enterprise.

Received the title of technology-based small and medium-sized enterprise in 2019.

In 2019, it won the title of Kaifeng Food Processing Automation Engineering Technology Research Center.

Obtained the certificate of evaluation for the integrated management system of industrialization and industrialization in 2019 

In 2020, Langrui Intelligent Manufacturing System was developed to assist users in achieving remote equipment control and digitalization of operating parameters.

In 2020, a new 1000 pound peeled melon seed production line was developed, and the improved peeled fryer had excellent cleaning efficiency and glossiness. The new dust removal system was equipped to filter and empty the dust to 1 micron (12500 mesh), which can be directly discharged and meet strict environmental requirements.
