Vacuum rake dryer is mainly used for drying explosive, easily oxidized and paste materials. Under vacuum conditions, the boiling point of the solvent is reduced, and the air is isolated, so it avoids oxidation, overheating and deterioration of material during the drying process. The heating medium (hot water, heat transfer oil or steam) is introduced into the jacket. A certain amount of wet materials are added into the drying chamber. The rake shaft stirs the materials to heat them evenly. After the materials meet the drying requirements, open the discharge valve at the lower part of the drying chamber to allow the materials to move to the middle under the stirring of the rake shaft for discharging.

Three scientific research achievements of Suzhou Metrology and Testing Institute won the utility model patent certificate
[ Instrument network instrument research and development ] Recently, three research results of Suzhou Metrology and Testing Institute "a weight picking device", "a small gas flow meter calibration device", "a positioning for standard ball roundness measurement" The fixture has obtained the utility model patent certificate issued by the State Intellectual Property Office.
“A weight picking device†is derived from the scientific research results of the weighing instrument testing room of the Metrology and Testing Institute of Suzhou. The device can realize automatic clamping and handling of weights of different types, different sizes and different grades, and solves the problems of low manual handling efficiency and potential safety hazards in the prior art, and improves the efficiency of weight verification.
“A micro gas flowmeter calibration device†is derived from the scientific research results of the flow test room of the Metrology and Testing Institute of Suzhou. The device can be connected to medium and high pressure gas, and has the advantages of reliable operation, convenient operation, adjustable pressure and short verification time, and greatly improves the calibration precision of the minute gas.
“A positioning fixture for standard ball roundness measurement†is derived from the scientific research results of the National Flat Panel Display Industry Measurement and Testing Center of Suzhou Metrology and Testing Institute. The positioning fixture can automatically center and position the standard ball to be tested, and has the advantages of simple structure, convenient operation and good repeatability, and greatly improves the measurement efficiency and precision of the standard ball.
