System principle and application scope

This equipment is a vacuum drying device optimized and upgraded for the common defects of conventional vacuum drying ovens, including large internal temperature difference, low drying speed, inconsistent drying degree of upper and lower materials, material foaming and overflow, and prolonged drying cycle. It is widely applied for low-temperature drying in pharmaceutical, food, light industry, chemical and other industries.
Equipped with heating radiators and internal heating plates, the equipment can rapidly break material bubbles after heating. It features uniform internal temperature, fast drying speed, low pollution, energy conservation and high production efficiency, without damaging the internal quality of dried products.
The equipment heats and dries materials through internal plates and cabinet jackets under vacuum conditions. A vacuum pump exhausts air and moisture to form a vacuum working environment and lower the boiling point of water, realizing high-efficiency drying at low temperature with full heat utilization and zero impurity contamination during operation.
Adopting static vacuum drying, it causes no damage to material shapes. Clean air can quickly eliminate material bubbles, fully complying with GMP standards. A high-performance PLC realizes full-process detection and automatic adjustment of working pressure and temperature, and outputs operation reports in real time for filing and traceability.
General process flow (custom programs available according to user requirements)
Preparation → Heating up → Drying → Pressure relief → Completion
Note: Standard one-piece molding drying plates are recommended with no cleaning dead angles.

Product introduction

The equipment adopts the "pulse" laminar flow vacuum drying principle and it is a high efficient low-temperature drying method. The equipment can use steam, hot water and electricity as heat source. At the same time, it can be equipped with saturated and circulating steam for sterilization, with ozone for disinfection. It also have on-line cleaning or soaking cleaning function.

Product advantages

1. The bottleneck of low drying efficiency of traditional Chinese medicine extract is solved, and the efficiency of this equipment technology is 2-10 times higher than that of traditional equipment;
2. The conformity between the actual production of materials and the drying process is solved, and the equipment production process is stable and the process is controllable;
3. It realizes sterilization and drying of materials in the same container, saving process steps, production space, equipment investment, energy consumption and labor cost;
4. It solves the problem of difficult equipment cleaning and is equipped with an on-line cleaning function. The internal drying car is designed to be movable with independently detachable plate layers, and matched with an external trolley for more convenient cleaning;
5. It addresses the drying difficulties of small and medium-batch and multi-variety materials, delivering higher flexibility in actual production;
6. It avoids carbonization and coking during material drying, ensures no degradation of effective material components, and greatly improves product quality;
7. It solves the problem of uneven material drying that requires secondary drying, which easily causes inconsistent color and unstable properties of materials;
8. It optimizes the porosity of dried materials. The finished materials present a honeycomb structure with excellent dissolution performance;
9. It solves common problems including difficult material collection, knocking deformation, low yield and excessive metal ions. The equipment adopts FDA-compliant materials to guarantee product safety;
10. It eliminates foaming and material loss during the drying process via innovative detection methods and patented technologies;
11. It reduces high energy consumption and long drying cycle of traditional equipment, cutting the production cost by more than 80%;
12. The equipment supports automatic material feeding and discharging, as well as in-box automatic cooling, which greatly reduces labor consumption and labor intensity, and shortens operation and cooling time.
