I.Project Background Longan, a specialty fruit of southern China, demands extremely high quality and taste during drying. Traditional drying methods, such as air drying or coal-fired drying, are susceptible to weather conditions, consume high energy, and cause significant pollution. To improve longan drying efficiency and reduce energy consumption, a food processing company introduced an air-energy heat pump drying system equipped with a 7-meter multi-layer mesh belt dryer, achieving intelligent, energy-saving drying.   II.Customer Requirements Energy saving and environmental protection: Avoiding highly polluting heat sources such as coal and oil, complying with environmental protection policies. Efficient and stable: Ensures even drying of longan, achieving a golden color, plump flesh, and a moisture content that meets standards (≤18%). Automated control: Reduces manual intervention, precisely controls temperature and humidity, and improves production efficiency.   III. Solution 1.Equipment Configuration Heat Source System: 25P Air-to-Air Heat Pump Unit (Heating Capacity ≥ 75kW, COP ≥ 3.5) Drying Unit: 7-meter multi-layer mesh belt drying room (304 stainless steel mesh) Control System: PLC intelligent temperature and humidity control, supporting staged adjustment (preheating → high-temperature drying → uniform humidity distribution → cooling)   2.Drying Process Phase 1 (Preheating): Temperature set to 50°C ± 2°C for 1 hour to remove...

1.Customer Needs The Guangxi Nanning Papaya Processing Company is a key local agricultural product deep-processing enterprise, specializing in papaya shreds and preserved fruit. With growing market demand, traditional drying methods face significant challenges: Insufficient production capacity: Relying on natural drying, the daily processing capacity is less than 5 tons, unable to meet order demand. Unstable quality: Manual turning and drying results in uneven papaya shreds, which are prone to oxidation and discoloration, resulting in a low pass rate of only 70%. High energy consumption and pollution: Traditional coal-fired drying is costly and does not comply with environmental regulations.   2.Jinlu Machinery Customized Drying Equipment To meet customer needs, we customized a six-layer, 18-meter-long, 2.3-meter-wide, fully automatic electric heated mesh belt dryer. Key highlights include: Ultra-large capacity design: The six-layer mesh belt structure provides an effective drying area of 248 square meters, capable of processing 2.5 tons of fresh papaya shreds per batch, increasing daily production capacity to 15-18 tons of dried product. Precision Electric Heating System: Utilizing intelligent PID temperature control (adjustable from 30-85°C) and independent zone control, this system ensures uniform heating and color of the shredded papaya, while reducing nutrient loss by 40%. Energy-saving and environmentally friendly: Compared...

1.Customer Needs: Addressing the Three Pain Points of Traditional Drying   A large chili pepper processing company in Guizhou faced three core challenges: Capacity Bottleneck: Traditional coal-fired drying rooms can only process 5 tons per day, resulting in a significant backlog of orders during peak season. Environmental Pressure: Coal-fired drying produces excessive SO₂ emissions, leading to rectification requirements from environmental protection authorities. Quality Fluctuation: Manual temperature control results in uneven color in finished products, leading to customer complaints regarding export orders. Special Requirements:   Needs to adapt to Guizhou’s rainy climate (average annual humidity above 80%) and process chili peppers such as shiitake mushrooms and string peppers. Local Specialty Varieties   2.Customized Solutions: Precisely Matched in Four Key Elements Jinlu Machinery provides a comprehensive solution combining “equipment + process + energy + service”: ① Structural Innovation 13-meter Ultra-Long, Six-Layer Design: A “wave-like” mesh belt layout extends the pepper turning path by 30% Anti-Condensation Design: A 5cm insulation layer is installed on the top of the drying chamber to address condensation issues in Guizhou’s high humidity environment   ② Intelligent Control System Equipped with an AI moisture prediction model, it automatically adjusts drying parameters through real-time image analysis Mobile app allows...

1.Project Background Apricots are nutritious, but fresh fruit is perishable. Traditional drying methods are significantly affected by weather, resulting in inconsistent quality. An agricultural cooperative in Xinjiang produces 50 tons of fresh apricots annually. Previously, low drying efficiency and high energy consumption led to high processing costs. In 2025, the cooperative introduced Jinlu Machinery’s high-efficiency heat pump dryer, significantly improving the quality and production capacity of dried apricots and enabling large-scale production.   2.Core Advantages of Jinlu Machinery Dryers ① Precision Temperature Control System Utilizing PLC intelligent control, the three-stage temperature control with an accuracy of ±1°C avoids the “burnt outside, wet inside” problem associated with temperature fluctuations in traditional equipment. Application Case: During the drying of dried apricots, the temperature automatically switches from 50°C to 60°C to 55°C, evenly removing moisture and resulting in a golden, soft, and chewy finished product. ② High-Efficiency and Energy-Saving Design Heat recovery technology reduces energy consumption by 30%, reducing drying costs by 200 yuan per batch (based on a 500kg batch) compared to traditional electric heating. Data Comparison: Processing 1 ton of dried apricots costs only 150 yuan in electricity (the industry average is 250 yuan). ③ Large-Capacity Layered Drying Customized tray layout...

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....
