Abstract
A method for applying an air suspension of minute solid particles of CIPC to a potato storage facility at ambient temperatures. The minute solid particles are produced from larger solid particles of solid CIPC by micronizing the larger particles.
Claims12
A method of providing a cold aerosol of substantially pure solid particles of CIPC for treatment of a vegetable storage facility comprising:
- micronizing solid CIPC at a temperature below about 105° F. in a micronizer to form a cloud of cold micronized solid particles of CIPC;
- directing an air stream into said cloud of micronized solid particles of CIPC, said air stream having a temperature less than the melting point of said CIPC to form an expanded cloud of solid particles of CIPC maintained at a temperature of less than about 105° F.;
- separating larger solid particles of CIPC from smaller particles of CIPC in said expanded cloud of CIPC while maintaining temperatures of solid particles of CIPC less than the melting point of CIPC to form a stable aerosol of said smaller particles of CIPC;
- and
- directing said aerosol to the internal space of a vegetable storage facility to deposit small solid CIPC particles upon the contents of said facility.
A method for comminution of larger particles of solid CIPC to micron-sized particles of CIPC comprising:
- feeding particles of solid CIPC into a micronizing device having rapidly moving fragmentation elements;
- feeding frozen particles of another chemical into said micronizing device wherein said frozen particles have a melting point significantly below the melting point of CIPC to maintain the interior surfaces of said micronizing device at temperatures less than melting point of CIPC
- introducing a carrier gas stream into said micronizing device.
A method for micronizing larger particles of CIPC in a micronizing device having fragmentation elements to form micron-sized particles of CIPC comprising:
- feeding a slurry of CIPC particles in a liquid carrier (including water) into the fragmentation elements of said micronizing devices, said CIPC being substantially insoluble in said liquid carrier and maintaining the temperature within said micronized device below about 105° F.;
- feeding a carrier air stream into said micronizing device in sufficient volume to carry minute liquid droplets of said liquid carrier and micron-sized particles of CIPC as a stable suspension from said micronizing devices for application to stored potatoes.
