Recently, Changzhou Jinwang Drying has launched a new closed-loop boiling dryer to address the drying pain points of heat sensitive, easily oxidizable, and high-value materials. This device combines the core requirements of "low consumption, cleanliness, and controllability" with the drying process. By optimizing the airflow circulation and temperature control design, it has formed characteristics in energy consumption control, material protection, and environmental protection. Currently, it has completed pilot applications in the fields of pharmaceutical intermediates, fine chemicals, food additives, etc., and has received positive feedback from users.
1、 Focus on the pain points of dryness and optimize the core design
The design of a closed-loop boiling dryer revolves around material characteristics and production needs. In response to the problem of high heat loss in traditional drying equipment, the equipment adopts a fully enclosed circulating airflow system. After the hot air is used in the drying chamber, it is recovered by a heat exchanger and sent back into the chamber to reduce heat discharge and energy consumption; In response to the problem of easy deactivation of heat sensitive materials (such as enzyme preparations and probiotics) during drying, the equipment is equipped with a precise temperature control module, which can stably control the drying temperature at 30-80 ℃ (error ≤± 2 ℃), combined with low-speed boiling airflow, to avoid local overheating of the material and ensure its activity.
In terms of environmental protection and material recycling, the equipment breaks through the traditional open drying mode and is equipped with efficient filtering devices, which can intercept the material dust generated during the drying process (interception rate ≥ 99.5%), reducing material loss and avoiding dust overflow and environmental pollution; At the same time, the solvent in the circulating airflow can be collected through a condensation recovery device, which is suitable for the drying needs of solvent containing materials (such as certain chemical intermediates) and meets the requirements of green production.
2、 Supported by stable performance and adaptable to multiple industry standards
The equipment pays attention to details in terms of performance stability and compliance: all parts in contact with the material are made of 316L stainless steel, with surface polishing treatment (roughness Ra ≤ 0.8 μ m), in compliance with GMP and food grade hygiene standards, and suitable for the strict hygiene requirements in the pharmaceutical and food fields; The airflow distribution inside the drying chamber is uniform, and the boiling state of the material can be controlled by adjusting the airflow speed to avoid material agglomeration and ensure uniform moisture content of the dried product (deviation ≤± 0.5%); In addition, the equipment is equipped with safety devices such as over temperature alarm, over pressure protection, and abnormal airflow reminder, which automatically shut down in case of abnormalities to ensure production safety.
According to different production capacity requirements, the equipment provides various drying chamber volume options ranging from 0.5-5m ³, and supports adjusting the internal flow guide structure based on material characteristics (such as particle size and density) to ensure seamless integration with existing production lines and reduce renovation investment.
3、 Effective implementation and customer recognition
In the field of pharmaceutical intermediates, a pharmaceutical company uses this equipment to dry cephalosporin intermediates. The closed loop system avoids material contact with the outside world, and the product purity remains stable. At the same time, energy consumption is reduced by 25% compared to traditional equipment; In the food additive industry, a certain enterprise focuses on drying probiotic powder and precise temperature control to increase the survival rate of probiotics to over 85%, meeting product quality requirements.
Since the equipment has been running for two months, the drying efficiency has been stable, dust loss is almost negligible, and the workshop environment is cleaner. The production manager of a fine chemical enterprise said that the practicality and environmental friendliness of the equipment have brought practical help to the production of the enterprise.
4、 Improve service guarantee and assist in long-term operation
Changzhou Jinwang Drying synchronously builds a full cycle service system: In the pre-sales stage, the technical team provides customized solutions based on material characteristics and production capacity requirements, including drying parameter settings and suggestions for auxiliary equipment matching; During the mid sales phase, arrange professional personnel to come on-site for installation and debugging, and guide operators to master equipment operation and daily maintenance skills; Establish a 24-hour response mechanism during the after-sales stage, providing regular inspections and parts replacement services to ensure the long-term stable operation of the equipment.
The person in charge of Jinwang Drying in Changzhou City stated that in the future, they will continue to optimize equipment performance based on market feedback, develop specialized modules suitable for high viscosity and easily agglomerated materials, and provide drying solutions that meet the needs of more industries.
