The embodiment of the invention provides a tobacco shred flow control method before sublimation of expanded tobacco shreds. The method includes measuring the weight W of the dry ice tobacco shreds andthe preset flow F of the set dry ice tobaccos; substituting into a first preset formula to obtain time T, and substituting the time T into a second preset formula to obtain a frequency FQ, with the preset total frequency FQT being a preset constant; and controlling operation of a quantitative belt through the frequency FQ. According to the embodiment of the method, the frequency FQ is controlledby acquiring the real-time dry ice tobacco weight W, and the operation of the quantitative belt is controlled through the frequency FQ, so that the real-time control on the operation of the quantitative belt is realized. According to the control mode of the quantitative belt through the frequency FQ provided by the embodiment of the invention, the conversion from manual adjustment to automatic control is realized, and the intensity of manual labor is reduced; the flow stability of the dry ice tobacco shreds before sublimation is effectively improved, and the flow and moisture stability of thetobacco shreds after sublimation are also obviously improved.
Description
technical field [0001] The invention belongs to the technical field of carbon dioxide shredded tobacco expansion, and in particular relates to a method and device for controlling the flow rate of shredded tobacco before sublimation of expanded shredded tobacco. Background technique [0002] Carbon dioxide tobacco expansion technology (Dry Ice Expanded Tobacco, referred to as DIET) can be roughly divided into three categories, namely, the A type of the American Elcor Industrial Gas Company (AIRCO), the B type of the British American Tobacco Company (BAT), and the Qinhuangdao Tobacco Machinery Co., Ltd. Form C of the responsible company. The basic process principle of this technology is to soak the shredded tobacco with liquid carbon dioxide, and form dry ice inside and on the surface of the shredded tobacco. The shredded tobacco with dry ice is quickly sucked into the sublimation tube through the Venturi tube, and the dry ice is rapidly sublimated in the hot air at about 330°...
