I. Project Background Named for their resemblance to deer antlers, deer antler mushrooms are prized for their crisp texture and rich nutritional content; consequently, demand for them in the edible mushroom market has been steadily rising in recent years. However, due to their high moisture content and delicate tissue structure, these mushrooms are highly sensitive to drying temperature and duration. Improper temperature control can easily lead to issues such as surface scorching, internal dampness, discoloration, or a loss of aroma—factors that directly impact the product’s grade and market price. Therefore, selecting drying equipment that offers precise temperature control, uniform airflow distribution, and consistent batch-to-batch performance is critical to the successful processing of deer antler mushrooms. II. Drying Solution and Equipment Advantages For this drying project, an 8-meter-long, 2-meter-wide, 5-layer mesh-belt dryer manufactured by Jinlu Machinery was utilized, employing an air-source heat pump as the heat source. Compared to traditional coal-fired or electric-resistance heating methods, air-source heat pumps offer distinct advantages, including high temperature control precision, low operating costs, and zero pollutant emissions—making them particularly well-suited for drying edible mushrooms and other materials with stringent quality requirements. Based on the specific drying characteristics of deer antler mushrooms, the technical team at...

A traditional Chinese medicinal herb processing enterprise in Guangdong Province has long specialized in the preliminary processing and sale of rhizomatous herbs, such as Solomon’s Seal (Yuzhu). As order volumes increased, their traditional sun-drying methods could no longer meet the required production capacity and quality standards. The client processes 10–12 tons of fresh Solomon’s Seal daily and requires that the moisture content after drying be ≤12%. Furthermore, the drying process must be uniform—avoiding scorched edges or blackened cores—while preserving the herb’s natural color and medicinal aroma. The equipment also needed to be adapted to Guangdong’s humid climate, featuring strong moisture extraction capabilities, all while maintaining controllable operating costs. Jinlu Machinery designed and customized a 9-meter, 5-layer biomass pellet-fired mesh belt dryer for the client, along with a tailored drying protocol. After being washed, peeled, and sliced ​​into 4–6 mm pieces, the Solomon’s Seal is spread evenly across the mesh belt. Utilizing the five-layer structure, the equipment operates at a constant temperature of 42°C throughout the entire process; the mesh belt’s conveyor speed is slowed down to extend the drying duration. The feeding section features fully open exhaust vents for maximum moisture extraction; the middle section employs moderate ventilation; and the...

Jinlu Machinery custom-engineered a 9-meter biomass-fueled mesh-belt dryer for Mr. Han in Shenyang; the core innovation of this system lies in its “multi-layer airflow” three-dimensional air duct design. Addressing the specific characteristics of waxy corn—namely its high moisture content and the high viscosity of its pectin—this design overcomes the limitations of traditional dryers, which often lead to material clumping and uneven heating. Through a multi-tiered air intake system, the equipment directs hot air upward, penetrating the mesh belt layer by layer. Each layer features independent controls for airflow volume and temperature, effectively preventing the corn kernels from forming a hard surface crust too quickly and ensuring that internal moisture is released uniformly. This approach fundamentally resolves the industry-wide challenge of waxy corn sticking together or scorching during the drying process. In the actual production workflow, this solution meticulously integrates the pre-processing and drying stages. The waxy corn is first processed by specialized threshing equipment to yield intact kernels, which are then spread evenly across the drying channel—a 9-meter-long conveyor system comprising multiple mesh-belt stages. As the mesh belt advances slowly, hot air permeates the layer of kernels sequentially, facilitating distinct stages: intensive moisture extraction, color setting, and gradual cooling. The...

1. Client Requirements Mr. Li, a client based in Guangxi—a region characterized by dense fruit and vegetable cultivation—specializes in processing dehydrated vegetables, primarily cucumbers and green beans. In the past, when utilizing traditional drying rooms to process cucumbers, he faced persistent challenges: the manual tray-loading process was tedious and labor-intensive; drying cycles were excessively long; heat distribution was uneven; the dried products often appeared yellowed or dull; fragmentation rates were high; and batch yields were too small to meet the demands for a stable supply. 2. Jinlu Machinery: Custom-Tailored Equipment Solution Upon installing Jinlu Machinery’s 10-meter multi-layer mesh belt dryer, the advantages became immediately apparent. Constructed entirely from food-grade 304 stainless steel, the machine features variable frequency speed control and intelligent systems for precise temperature and humidity regulation. Integrated with a cross-flow hot air circulation system, it enables a seamless, continuous workflow involving continuous feeding, drying, and discharging. The process is meticulously managed through three stages: rapid initial dehydration at 60–65°C; constant-temperature dehumidification at 50–55°C during the intermediate phase; and a gentle, final drying and shaping stage at 45–50°C. This precise control ensures the final product’s moisture content is maintained within a target range of 8% to 12%. Throughout the...
