Description
Technical Field
[0001] The utility model relates to the technical field of freeze drying machines, in particular to a freeze drying machine for washing plastic bottles. Background Art
[0002] After the plastic bottles are formed, the inner cavity of the plastic bottles needs to be cleaned. At present, when cleaning plastic bottles in batches, a freeze dryer is usually used for cleaning. Usually, freeze drying is a method of freezing the water-containing substance into a solid state, and then sublimating the water in it from a solid state into a gaseous state to remove water and preserve the substance. In the compressed air drying process, freeze drying is to lower the temperature of the compressed air so that the water in the compressed air is analyzed out. The working principle of the freeze dryer is the same as that of a refrigerator. After the compressed air passes through the frozen compressed air pipeline, the compressed air temperature drops to the required temperature to achieve the drying requirement.
[0003] When the existing freeze dryer is in use, it is necessary to dissipate heat inside the dryer. Therefore, when the equipment stops, the air will contain some impurities such as dust. These impurities will enter the interior of the dryer through the heat dissipation port and then accumulate on the inner wall of the heat exchanger, thereby affecting the efficiency and effect of the heat exchange. In addition, it is more troublesome to move the equipment. Therefore, a freeze dryer for washing plastic bottles is provided to solve the above problems. Utility Model Content
