Low-temperature pulse vacuum dryer is a kind of vacuum box-type drying device, belonging to the static vacuum class drying equipment, is working under negative pressure conditions, can be widely used in various industries of material drying, especially suitable for heat-sensitive materials or viscous materials, oxygen-containing working condition of the material drying is relatively harsh. The material is loaded in the drying disc and placed on the plate layer inside the box, so that a vacuum is formed inside the working chamber, which reduces the boiling point of water and speeds up the drying speed. Adopting (low temperature) hot water as the exchange medium, adopting the principle of ‘high vacuum’ laminar flow drying, and adopting the pricked bubble technology, it solves the bottleneck of easy blistering and overflowing, easy coking and carbonisation, easy oxidation and degradation of materials, long drying cycle, etc., and it is a kind of high efficiency and energy-saving drying method with low temperature. At the same time the box can be completed online cleaning or immersion cleaning function, is currently the most advanced, most energy-saving, most efficient one of the equipment.

Equipment features

Solve the bottleneck of low drying efficiency of traditional Chinese medicine extract, the equipment technology compared with the traditional equipment to improve the efficiency of more than 2~10 times;

Solved the problem of conformity between the actual production of materials and drying process, the equipment production process is stable and the process is controllable;

Solve the problem of difficult to clean the equipment, with online cleaning function, within the drying car designed for mobile, the plate layer alone can be detached, with the external car, cleaning is more convenient;

Solve the production of small batch, multi-species drying dilemma, more flexible in the actual production;

Solve the phenomenon of carbonisation and coking in the process of material drying, ensure that the effective ingredients of the material are not damaged, and greatly improve the quality of the product;

Solve the problem of uneven drying of materials, the need for secondary drying, making the material colour inconsistent, performance differences;

Solve the loose nature of the material after drying, the material is honeycomb, to ensure that the product dissolves well;

Solved the drying disc difficult to collect materials, knocking deformation, low yield, metal ions exceeding the standard and other phenomena, the use of FDA-compliant material to lay the bottom.

Solved the phenomenon of foaming and running material in the drying of materials, adopting advanced technology to detect and use technology to deal with;

Solve the problem of high energy consumption of equipment, drying time is too long, compared with the traditional equipment cost reduction of more than 80%;
