10results about How to "Reduce drying speed" patented technology

This invention relates to the field of natto processing, and more particularly to a multifunctional drying device for natto processing. It includes a shell, an attachment plate, a scraper, and a drive assembly; the attachment plate is fixedly connected to the shell; the drive assembly is connected to the shell; and the scraper is connected to the drive assembly. This invention dries natto fermentation liquid by heating it onto the shell, attachment plate, and rotating plate, avoiding the problem of incomplete drying of some natto fermentation liquid, which leads to poor atomization drying effect. Furthermore, the sliding plate moves back and forth, constantly changing the position of the atomizing nozzle, preventing the nozzle from remaining in the same position and causing uneven application of the natto fermentation liquid to the shell or attachment plate, resulting in uneven drying speeds. It also avoids the problem of significant heat loss caused by hot air leakage from the natto fermentation liquid outlet in existing technologies that use hot air for drying.
