Recently, Hanneng Technology’s online rice cooling system (Guleng Fresh Locking Tower) has been successfully implemented by a leading domestic grain and oil processing company. As the first domestic online rice cooling system to be put into industrial-scale application, the equipment has been running stably for half a year, successfully achieving the expected cooling target, and successfully solving the industry pain points in the rice cooling process during rice processing.
Promote the transformation of the rice processing industry towards continuity, efficiency and energy conservation, and provide a new technical solution for the grain processing industry to save grain and reduce losses.
As we all know, food security is a fundamental issue related to human survival, and reducing food loss is an important way to ensure food security.
In the rice processing process, cooling the rice after milling is a necessary process in the processing industry. However, the traditional cooling rice method has long-term problems of low efficiency and high losses, which restricts the high-quality development of the industry.
It is understood that when rice is processed into rice, the temperature will rise rapidly by 20 –
25°C, if the temperature is not cooled down in time, the excessive temperature difference between the inside and outside will cause cracks in the rice waist. Such cracked rice will be easily broken in the subsequent polishing process, directly increasing the breakage rate and affecting the economic benefits of the company. At the same time, the surface of high-temperature rice softens and is easily gelatinized after being polished with water, making it difficult to achieve ideal brightness and whiteness, affecting the rice grade. In addition, high temperatures will also cause gelatinized rice to adhere to the polishing equipment, which not only increases equipment maintenance and cleaning pressure, but also poses food safety risks.
Although the low-temperature rising rice milling process has been developed in the industry, and methods such as air cooling and natural cooling of rice in cooling rice warehouses are commonly used, there are obvious limitations: First, the low-temperature rising rice milling process cannot achieve the best cooling effect. The rice will still heat up significantly in the rice mill, and it needs to continue to cool down. In addition, low-temperature rising rice milling requires a fan to continuously flow cold air, which consumes a lot of energy; second, it takes up to 12 –
24 hours a day, not only takes up a lot of factory space, but also cannot realize the seamless connection between rice milling and polishing, seriously affecting production efficiency; third, the rice is inefficient when it is left to cool in the cold rice warehouse, and it is difficult to reduce it to its optimal state. Rice is stored at high temperatures for a long time, resulting in nutrient loss and poor taste; fourth, cleaning the cold rice warehouse is also a problem, which increases the company’s operating costs and food safety risks.
As the requirements of the rice processing industry continue to increase, the backward productivity of the industry is constantly being eliminated.
In order to continue to maintain a leading position in the industry, all aspects of rice processing need to improve quality and efficiency, and the cold rice link is a very important part of it.
As an enterprise deeply engaged in the field of energy-saving technology and focusing on industrial equipment innovation, Hanneng Technology relied on its strong scientific research strength and technical advantages to develop a targeted online rice cooling system (Guleng Cooling Tower), successfully solving the above-mentioned industry pain points.
The system adopts an indirect water-cooling cooling design, and the operating principle is scientific and efficient: first, after the rice comes out of the rice mill, it directly enters the Hanneng Technology online cooling system. The rice and cold water exchange heat indirectly through the plates to achieve continuous step cooling, which can not only minimize the temperature difference, effectively prevent the broken rice phenomenon caused by sudden cooling, but also achieve online instant cooling of the rice after milling; second, the entire system operates automatically to cool the rice to the set temperature.
The cooled rice can directly enter the polishing machine or finished product warehouse, completely breaking the bottleneck of the traditional rice cooling process and greatly improving production continuity.
Compared with traditional air-cooling systems and cold rice warehouses, Hanneng Technology’s online rice-cooling system has six core advantages: First, indirect heat exchange can better maintain the moisture content of rice compared to air cooling, effectively reducing weight loss and increasing corporate profit margins; second, the stepped cooling design avoids rice bursting caused by sudden cooling and ensures rice quality.
The third is that the cooling is efficient and the rate is controllable, which better meets the actual needs of the enterprise; the fourth is low energy consumption, which greatly reduces the operating costs of the enterprise; the fifth is the fully automated operation, which reduces the human resource cost of the cold rice process; the sixth is that it occupies a small area, and the required building area is only about 1/12 of the cold rice warehouse with the same processing capacity.
In terms of product details, this system fully meets the food safety needs of the rice processing industry. It adopts an anti-material accumulation and no dead space design. The interior is made of stainless steel. It has high cleanliness and is easy for daily maintenance. It fully complies with the hygiene standards of the food processing industry.
This application by the leading domestic grain and oil processing enterprise is the first time that this system has been put into industrial scale application, and is also a strong confirmation of Hanneng Technology’s technical strength and product reliability.
As a leading company in the rice processing industry, the company has always been committed to promoting digital and intelligent transformation to improve production efficiency and product quality. This time, it chose Hanneng Technology’s online rice cooling system because of its technological innovation and practical feasibility.
After half a year of continuous operation, the system has performed extremely well, not only stably achieving the expected cooling target and accurately reducing the rice temperature to normal temperature, but also performing outstandingly in controlling the broken rice rate and cracked waist rate.
At the same time, the rice cooling time has been significantly shortened from the original 12-24 hours to 1 hour, completely realizing the continuous operation of rice processing, greatly reducing the demand for factory space in the rice cooling process, effectively reducing the construction area, reducing the company’s construction costs, easing space pressure, and significantly improving production efficiency, bringing considerable economic benefits to the company.
The relevant person in charge of the company revealed that the rice is quickly cooled through the online cooling system, which can also preserve the nutrition and flavor of the rice to the maximum extent, and avoid the damage to the quality of the rice caused by long-term high temperature. This is also a topic they need to further study in the future – how to better combine the efficiency and quality of rice processing to make the rice more delicious and nutritious.
As the first online rice cooling system in the industry that has been put into industrial-scale application, this innovative achievement of Hanneng Technology not only fills the relevant technical gaps in the industry, but also provides a replicable and scalable solution for the rice processing industry to save grain, reduce losses, and improve quality and efficiency.
Relying on years of technological accumulation in the fields of heat transfer and energy conservation, Hanneng Technology has always been driven by innovation. The successful application of the online cooling rice system further demonstrates the company’s strength and responsibility in the field of industrial equipment innovation.
In the future, Hanneng Technology will continue to delve deeply into the field of rice processing equipment, focus on industry needs, continuously optimize product performance, promote technology iterative upgrades, provide more rice processing companies with efficient, energy-saving, and safe cool rice solutions, assist the transformation and upgrading of the grain processing industry, protect food security with technological innovation, and inject strong impetus into the high-quality development of the industry.
