[0024] Second embodiment: apply the circulating fluidized bed ultraviolet sterilization equipment of the first embodiment to carry out the sterilization method of pine pollen, comprise the steps:
[0025] S1. Adjustment and start-up of the initial state of the equipment: close the discharge valve 5, the air inlet valve 13 and the feeding valve 11, open the circulation cut-off valve 6, start the fan 1, start the ultraviolet sterilization lamp 20, and open the inlet after the fan 1 is started. Air valve 13, adjust the opening of the regulating valve 9 between 5% and 40%, so that the inside of the bag filter 7 and the bag filter 8 are in a positive pressure state, that is, part of the air flow is from the exhaust port of the bag filter 42 discharge;
[0026] S2, feeding: open the feeding valve 11 and add pine pollen with a moisture content of 10%, the amount of pine pollen added is 15% of the volume of the circulation channel, and the pine pollen enters the circulation channel un...

Abstract
The invention discloses circulating fluidized bedultraviolet sterilizing equipment and a sterilizing method of the circulating fluidized bedultraviolet sterilizing equipment on pollen pini. According to the circulating fluidized bedultraviolet sterilizing equipment, a circulating channel is formed through an air blower (1), a circulating pipeline I (2), a cyclonedust collector (3), a circulating pipeline II (4), a circulating stop valve (6), a bag type dust collector (7), a regulating valve (9), an air intake tee joint (10) and a circulating pipeline III (12); the sterilization is realized by enabling a material to continuously approach an ultraviolet sterilizing lamp tube by adopting a method that a fluidized material circularly flows in the circulating channel. The circulating fluidized bed ultraviolet sterilizing equipment disclosed by the invention is simple in structure.
Description
technical field [0001] The invention relates to a circulating fluidized bed ultraviolet sterilization equipment suitable for powder materials and granular materials and a sterilization method for pine pollen. Background technique [0002] Invention patent ZL201010162898.4 discloses an ultraviolet sterilization equipment for powder materials, which is improved on the basis of a boiling dryer and has a complex structure. [0003] Pine pollen is a micron-sized powder. Dried pine pollen is easy to fly, does not agglomerate under normal conditions, and exists in the form of a single cell. At present, pine pollen is generally not sterilized in the raw materialprocessing stage, but pine pollen will inevitably be contaminated by microorganisms during the growth and raw material production stages, and the existence of microorganisms will lead to a decrease in the quality of pine pollen. Contents of the invention [0004] The technical problem to be solved by the present invention...
