Bolang just finished the equipment installation and commissioning for ZhenzhenLaolao Company, one of the most famous food factories in China

ZhenzhenLaolao Company has advanced zongzi (traditional Chinese rice-pudding) production line in China, with a daily production capacity of more than 1.5 million. Quick freezing ensures that the zongzi retains its original flavor, texture, and nutritional value.
A quick freezing production line is an efficient and effective way to produce high-quality zongzi that can be sold and distributed to supermarkets and retail stores, ensuring that customers have access to healthy and delicious zongzi all year round.


The function of the quick-frozen cold storage is to quickly freeze the food at constant temperature (such as fresh meat, fresh fish and shrimp, fresh vegetables and fruits, frozen pasta) or unfrozen cold drinks to the cold storage temperature (generally -15 ~ -18 ℃), so that it can be stored in the cold storage.


Food frozen by quick freezing cold storage, its nutritional content broken less, high fresh degree, can be stored in cold storage for a long time. There are many ways to improve the efficiency of cold storage refrigeration system and reduce its energy consumption. But the first thought, more limited to daily use management, such as through timely defrosting, improve the evaporator heat transfer efficiency; Reduce the number of cold storage door opening, add air curtain machine in the door to reduce cold escape; Do a good job of cold storage enclosure structure maintenance. All this is effective for improving the efficiency of cold storage transportation and reducing energy consumption.


There is still a lot of work to be done in the technical management rules of the cold loading and installation process. There is no technical difficulty and it can be realized through short-term training and intensive management of operators.
