Continuous technological R&D innovation, stable product performance, reliable production capacity, and meticulous service quality assurance have won the unanimous approval and acclaim of industry peers.

The growth of Zhongchen brand would not have been possible without the support and push from our customers.

Coca-Cola and Hahaha are international famous enterprises and national famous brand enterprises respectively. In the past, the high-end customers' equipment was almost dominated by imported goods. They have nearly rigorous requirements for suppliers and equipment. For example, Coca-Cola not only has high requirements for individual machines, but also sets strict evaluation and acceptance standards for the production lines composed of these individual machines. In the production line industry standards of our country, there are only technical indicators such as production capacity, energy consumption, and bottle damage. However, Coca-Cola has set some additional evaluation indicators for production lines, such as the determination of the engineering ability index (Cpk). The engineering ability index is also called the process ability index, which is a statistical parameter that measures the inherent ability characteristics and long-term stable state of a system.

After years of efforts, Hefei Zhongchen has established long-term cooperative alliances with high-end enterprises such as Coca-Cola and Wahaha. Meanwhile, Zhongchen has jointly set up a beverage filling laboratory with Taikoo Coca-Cola to explore and develop new structures and technologies specifically for beverage filling lines. Zhongchen's products not only meet the requirements of Coca-Cola on a standalone basis, but also have passed the test of the overall system effect after the whole line is linked, winning praise from customers.

The progress of product technology cannot be achieved without the encouragement and assistance of customers.

Develop products with technological features that meet market needs.

After years of effort, Hefei Zhongchen Light Machinery Co., Ltd. has accumulated strong technical R&D innovation capabilities. In order to maintain technological leadership, the company has proposed a timely technical leadership strategy of "enterprise independent innovation as the main body, digestion and absorption of foreign technology as the basis, integration of production, learning and research as the driving force, and domestic and foreign market demand as the guide". Through resource integration, the company has successively cooperated with domestic top universities such as the University of Science and Technology of China and Hefei University of Technology, as well as research institutions such as Hefei General Institute of Science and Technology and the Affiliated Hospital of Anhui Medical University, to solve a series of major technical problems; by combining the development directions of domestic and foreign technology and the scientific and technological development trends of the industry, and closely following market demand, the company has developed a series of major achievements in the production of medium-to-high-speed beverage filling production lines.

1. Continuously advancing hybrid technology

Hefei Zhongchen Light Machinery Co. has always attached great importance to technological development and innovation. Since the early 1980s, it has introduced beer and beverage filling technology, and has been following the latest international advanced technology. In recent years, it has broadened its innovative thinking and increased its technological innovation efforts, taking multi-channel and all-around approaches to technological innovation to develop new products with high technological content and high added value that meet customer needs, thus forming a trend of leading the new wave of domestic packaging technology.

The CO2-containing beverage mixer produced by Hefei Zhongchen is the top-selling product in the domestic market, with its advanced technology, product quality and performance at the top level in China. However, Zhongchen people are not satisfied with the status quo and have been exploring and improving new technologies and mechanisms. They have re-examined the old products and used the basic scientific principles of fluid mechanics that they have mastered to conduct bold exploration and innovation in the mixing mechanisms. Through research on the characteristics and laws of the flow of beverage liquids and CO2 gas, as well as the nozzles and outlets, they have established a unique mechanical model of beverage liquids and found a more effective way and approach to achieve gas-liquid mixing. They have successfully applied this to product development and achieved an upgrade of products. This also reflects the pursuit of excellence and achievements of Hefei Zhongchen Light Industry Machinery Co., Ltd., a leading Chinese manufacturer of beverage and beer equipment, in creating fine products. For example, the super clean filling and capping machine specially developed for Wahaha Group and the gas dissolution technology mixing machine, which not only replaced imported equipment but also obtained several national patents for technology; the newly developed "high-efficiency carbonation mixing machine" has reached the leading level of domestic beverage industry in terms of overall technology, and was identified as a scientific and technological achievement by the Anhui Provincial Science and Technology Department in 2009; the subsequent development of the high-precision, high-capacity flowmeter mixing machine successfully made its debut at the 2009 Munich International Drinks and Liquid Food Technology Exhibition, becoming a highlight of the entire Chinese pavilion at the exhibition. Its advanced technology is already on par with European exhibitors and has attracted the attention of exhibitors and trade visitors from all over the world, as well as the industry. It has performed well in both Coca-Cola and Wahaha, and has become the preferred equipment of large and medium-sized beverage equipment manufacturers.

2. New volumetric filling technology

The filling machine is one of the main equipment on the filling line. The current gas-containing liquid filling generally adopts the equal pressure filling technology. The advantage of this technology is simple control, but the capacity of the liquid is affected by the back pressure gas pressure. Hefei Zhongchen Light Machinery Co., Ltd. has recently developed a brand new constant volume filling technology, which abandoned the liquid level control technology of equal pressure filling and adopted the single flowmeter control technology. By controlling the flow of the liquid with a flowmeter, the volume of the filled liquid can be controlled, thus overcoming the shortcomings of traditional filling technology and achieving accurate measurement. For example, for a 600ml bottle of cola, the measurement accuracy of constant volume filling can reach ±1.5g, while the traditional constant liquid level filling technology can only reach ±4g, or even greater errors; filling is stable, effectively avoiding the large foam caused by instant gas discharge, and preventing the loss of beverages to ensure that the net capacity of the filling meets the requirements; the online control of no bottle or burst bottle can be achieved at the same time, and the filling process of other valves is not affected.

3) New flexible capping technology

Due to the diversity of consumer needs, manufacturers have introduced a wide range of PET bottle shapes and correspondingly diverse bottle mouths, such as 28-mouth, 30-mouth, 38-mouth, etc., as well as different numbers of screw cap turns. In order to meet market demand, Hefei Zhongchen Light Machinery Co., Ltd. has developed flexible capping technology that is compatible with different types of caps. It ensures the number of rotations when packaging carbonated liquids, ensuring the airtightness of the cap; it automatically adjusts the number of cap turns when packaging non-carbonated liquids, preventing the cap from being damaged, and the conversion does not require any change parts, which is convenient and reliable, greatly improving production efficiency. This technology has been widely used in the water-gas dual-use line of Wahaha Group and the 1881 short-mouth bottle packaging of Taikoo Cola, greatly reducing the waste of bottles and caps.

The future market for filling equipment will feature green, environmentally-friendly, energy-saving, high-quality, efficient, and branded sales. This also determines that beverage and beer filling equipment must continuously innovate technologically to keep pace with the development of beverages and beer. Innovation is not only the need for enterprises to enhance their own competitiveness, but also the social responsibility that enterprises should bear. Hefei Zhongchen will further strengthen its own equipment's technological R&D efforts to meet market needs and promote the common development and progress of the equipment industry.
