Problems solved by technology
The current dryer has a single drying method, often only after the drying gas is heated, the drying gas is continuously circulated in the device to dry the package, and the moisture in the drying gas is not removed, so that the drying effect of the drying gas is getting better and better. The worse it is, it will even affect the dyeing quality of cheese
Some dryers adopt the method of direct row drying, that is, the external air is continuously introduced to dry the materials, and the dried gas is directly discharged out of the device, resulting in a large waste of drying gas.

The invention discloses a package yarn dryer with multiple drying circulation circuits and its control method and control method. Through a valve, it performs preheating drying, condensation dehumidification drying, capacity expansion evaporation dehumidification drying, and direct discharge drying. Switch between four working modes to adapt to different drying situations and drying processes. The invention has multiple drying methods, and can select different drying methods according to different cheeses or different drying gases, or select corresponding drying methods according to the drying effect and drying speed, and has strong practicability and wide applicability , can adapt to different drying conditions and improve the drying effect of cheese.
Description
technical field [0001] The invention relates to the technical field of cheese drying, in particular to a control method of a dryer with multiple drying circulation circuits and the control method thereof. Background technique [0002] In order to ensure the dyeing quality of cheese during the production process, it is often necessary to seal and dry the cheese to avoid the external environment from affecting the dyeing effect of the cheese. The current drying method of the dryer is single, often only after the drying gas is heated, the drying gas is continuously circulated in the device to dry the package, and the moisture in the drying gas is not removed, so that the drying effect of the drying gas is getting better and better. The worse it is, it will even affect the dyeing quality of cheese. Some dryers adopt the method of direct row drying, that is, the external air is continuously introduced to dry the materials, and the dried gas is directly discharged out of the devi...
