Tofu Drying
With the development of the soy product industry towards automation and standardization, traditional drying methods are no longer able to meet modern production needs. Recently, a soy product enterprise in Wugang, Hunan Province purchased 20 electric heating intelligent drying rooms from Jinlu Machinery, achieving efficient drying of tofu jerky and significantly improving product quality and production capacity, becoming a typical case of industry technological upgrading.
1.Customer background: Traditional drying restricts development and urgently needs automated drying solutions
The enterprise is one of the key enterprises in Wugang Bean Products Industrial Park, mainly producing characteristic products such as dried tofu stewed, tiger skin dried tofu, with an annual output of more than 1000 tons, and the products are sold at home and abroad. In the past, enterprises relied on natural drying, which was greatly affected by weather conditions. High temperatures in summer could easily cause tofu to spoil, while rainy and cloudy winters extended the production cycle. In addition, manual drying was labor-intensive and hygiene conditions were difficult to guarantee. With the increase in order volume, traditional methods are no longer able to meet market demand, and enterprises urgently need a stable and efficient drying solution.
2.Customized design solution: intelligent temperature control+multi-layer drying, accurately matching production needs
After market research, the company ultimately chose a 20 plate electric heating intelligent drying room, which was customized by a professional drying equipment manufacturer. The core advantages include: ① Multi layer drying design: using 20 layer stainless steel trays, it can dry 500 kilograms of dried tofu at a time, which is 5 times more efficient than traditional drying. ② Precise temperature control system: equipped with PLC intelligent control, the temperature can be adjusted between 40 ℃ -80 ℃, avoiding high temperature damage to tofu taste and ensuring even evaporation of moisture. ③ Energy saving and environmental protection: Adopting electric heating and heat recovery technology, it saves 30% energy compared to coal-fired drying and meets food safety production standards. ④ Automated management: supports remote monitoring through mobile apps, adjusts drying parameters in real-time, reduces manual intervention, and lowers operating costs.
After the equipment was put into production, the drying time of dried tofu was shortened from 24 hours to 8 hours, the product qualification rate was increased to more than 98%, and the color and taste were more stable, providing high-quality raw materials for the subsequent brine processing process.
3.Customer review: “High drying efficiency, more stable product quality”
The production manager of the enterprise said, “In the past, we relied on the weather to make a living, but now we are completely unaffected by the environment. The drying room runs stably, the moisture control of tofu is precise, and the flavor after braising is more uniform.” In addition, the equipment has helped the enterprise pass the export food certification, further opening up the Southeast Asian market.
As the soy product industry develops towards intensification and intelligence, automation equipment such as electric heating and drying rooms will become the preferred upgrade for small and medium-sized enterprises. In the future, intelligent drying systems combined with IoT technology are expected to be further popularized, promoting the traditional soy product industry towards high-quality development.
