1.Customer Demand Dalian Xiangzong is engaged in seafood processing enterprises. It processes more than 500 tons of prawns and other aquatic products annually, and its products are mainly exported to high-end markets in Europe and the United States. With the increase in orders, traditional drying equipment has exposed three major pain points:   Low efficiency: drying takes 8-12 hours, and the production capacity bottleneck is prominent; unstable quality: temperature fluctuations result in a finished product rate of only 85%, and the shrimp body is prone to color difference or excessive dehydration; high energy consumption cost: coal-fired thermal efficiency is less than 40%, and manual drying is labor-intensive. Customers urgently need an intelligent drying solution that can take into account efficiency, quality and energy saving.   2.Design plan After field research, the technical team of Jinlu Machinery tailored a solution for it; Equipment selection: Use a rotary dryer with a 10-layer flip structure to simulate manual drying to ensure uniform heating; Equipped with electric heating, the thermal efficiency is increased to 75%, energy-saving and environmentally friendly; Process optimization: Set 90℃ constant temperature drying for 4 hours, and dynamically adjust the hot air circulation through the humidity sensor; The intelligent control system...

In a major pepper production area in Shaanxi, a local professional pepper processing factory faced many problems caused by traditional drying methods. Due to the changeable climate in Shaanxi, peppers that are dried naturally often encounter rainy weather, resulting in serious mold losses. At the same time, manual drying is inefficient, and only 500 kilograms of fresh peppers can be processed per day. The finished product has uneven color and serious aroma loss, which seriously affects product quality and market competitiveness.   In response to these problems, the Jinlu Machinery technical team customized a heat pump drying solution for the customer after a field investigation. The solution uses the RHP-1000 air-energy heat pump drying room, which uses an intelligent control system that can accurately adjust temperature and humidity. The drying process is divided into three stages: first, preheat at 40℃ for 1 hour to protect the oil cells on the pepper’s epidermis from damage; then dry at a constant temperature of 50-55℃ for 8-10 hours to ensure uniform evaporation of moisture; finally, return to 40℃ for 1 hour to make the pepper dry uniformly inside and outside.   After this drying system was put into use, the effect was immediate....

Polygonatum odoratum is a common Chinese medicinal material with the effects of nourishing yin, moistening dryness, promoting body fluid and quenching thirst. Fresh Polygonatum odoratum has a high water content and is not easy to preserve, so it needs to be dried and processed into Polygonatum odoratum slices for long-term storage and transportation. Jinlu Machinery takes the drying process of Polygonatum odoratum slices in a Chinese medicinal material processing plant as an example to introduce its process flow and key control points. 1.Processing process Raw material pretreatment Cleaning: Fresh Polygonatum odoratum is rinsed with running water to remove mud and impurities. Slicing: Use a slicer to cut Polygonatum odoratum into uniform slices of 3-5mm to ensure uniform drying. Drying process Drying equipment: Use air energy heat pump drying room, which has controllable temperature and is energy-saving and efficient. Drying parameters: First stage (low temperature dehydration): set the temperature to 50℃, humidity to 60%, and bake for 2 hours to remove surface moisture. Second stage (medium temperature drying): raise the temperature to 60℃, humidity to 40%, and bake for 4 hours to further evaporate the moisture. The third stage (high temperature setting): the temperature rises to 65℃, the humidity is 20%,...
