Closed algae powder cooling storage system

The utility model relates to a mechanical technical field of spirulina preparation especially relates to a closed algae powder cooling storage system, including two spray drier, pipeline, pulse bag dust collector ware, storage tank and draught fans, two spray drier install respectively pipeline is last, pipeline is connected to the upper portion of pulse bag dust collector ware, the sack cleaner lower part with the storage tank is connected, the draught fan with the pulse bag dust collector ware is connected. The utility model discloses realize the closed collection and quick cooling of algae powder, reduce on the one hand and collect in -process algae powder and external contact, reduce the microbiological contamination probability, on the other hand is algae powder from 80 DEG C of quick reductions to below 10 DEG C, the breeding of pollution abatement fungus. It is lower to below the critical point with algae powder temperature fast, reduced high temperature dwell time, reduce the heat collapse degree of biological activity compositions such as spirulina algae lan su, increase spirulina active ingredient content, improve product quality.
