In 2002, the three-layer and single-layer net band drying machine was successfully tested in baotou.

In 2003, the new baking machine and cooling machine were successfully trial-produced by qiqia food co., LTD.

In 2004, the three-layer two-side hot air circulation belt dryer was successfully tested in shandong sand food co., LTD. The three-layer two-side hot air circulating network belt dryer, with a unique structure design, can save more than 40% electricity year on year, and has the advantages of small area, high efficiency, energy saving, even drying and more crisp taste.

In 2005, China's first automatic continuous sunflower seed frying pan developed for many years was successfully tested in anhui, and obtained the national patent. It has the significance of mileage brand.

In 2005, our factory designed and produced a large automatic frying pan --- heat-conducting oil type sunflower seeds (peanut) automatic frying pan, which was the first of its kind in China. Large output, large time range of frying, low temperature and slow frying make the quality and taste of nuts better than high temperature, effectively prolong the shelf life of finished nuts.

Natural gas automatic frying pan developed and produced in 2007, which can be double-layered and continuously produced, is designed for nuts that need to be cooked for a long time. In the same year, it was successfully tested in anhui province.

In 2009, the first direct-fired nut automatic frying pan (patented product) was invented in China. Due to the unique combustion mode of the equipment and the change of material circulation mode, the output was raised by 20%, energy consumption was reduced by 20%, and the taste was more crisp.

In 2010, the development of automatic dipping machine (patented product) was successful, which completely changed the history of manual and semi-automatic dipping water in the stir-frying industry, and achieved the streamlined production from cooked system to packaging.

2011 domestic initiative seeds (nuts) heat conduction oil, natural gas making production line (patent products), the peeling melon seeds, watermelon seeds, pumpkin seeds, almond, nuts, wheat and so on need to long time making by intermittent production into a continuous production, and in the process of making artificial, achieve saving energy and reducing consumption, saving the purpose of easy operation;

In 2011, the multi-layer mesh belt dryer was successfully developed (patented product), which was first invented in China. The design of multi-layer mesh belt and unique hot air circulation mode made the material heated up and down at the same time, resulting in more uniform drying and crisper taste. Energy consumption was reduced by 20 percent year-on-year, and electricity consumption was reduced by 40 percent.

In 2012, the spiral recirculation automatic frying pan was successfully developed (patented product), which effectively solved the fatal defect of double-drum heat conducting oil frying pan, made the operation and maintenance easier, increased the output by 20% year on year, effectively saved energy and reduced consumption, and made nuts taste crisper. At present, it has been widely used in many manufacturers.

In 2013, the direct combustion frying pan was improved to reduce the combustion cost by 20%, achieving the highest energy consumption and the lowest energy consumption of the same output.

In 2014, I wrote the industrial standards of nut food drying equipment and nut food frying equipment of the ministry of light industry of China.

In 2014, China pioneered the dual-side hot air circulation belt dryer of natural gas direct combustion (patented product), the heating of natural gas direct combustion, clean exhaust emission, the utilization rate of natural gas is close to 100%, efficient and energy-saving, fast heating and accurate temperature control. The thermal energy consumption is reduced by 25%, which is lower than the same kind of equipment at home and abroad. The output is 30-40% higher than that of similar products;

In 2015, the intermittent hot air circulation dryer (patented product) was invented, which is 30%-40% more energy saving than the normal intermittent dryer.

The first liquid jacket type natural gas boiler, natural gas direct combustion type hot air stove. Advanced heating method, more efficient energy saving.

In 2016, the natural gas direct combustion hot air double-circulation belt dryer was successfully developed, with wide adjustment range of two-way hot air circulation, zonal temperature control, temperature and drying time, simple regulation and multi-use.

In 2016, the first fully automatic nut production line in China was successfully developed, enabling automatic and continuous production of tree nuts drying.

In 2017, the first multi-functional belt dryer (patented product) was successfully developed in China. According to the different drying materials, the dynamic and static drying mode can be arbitrarily converted, which is suitable for drying any materials.

       In 2018, the company developed nut direct fired automatic  Roaster and daily nut production line, which is mainly used for roasting nuts and flavoring & drying daily nut.
