PLG Series Vacuum Continuous Plate Drying machine (Vacuum continuous plate dryer) (continuous Plate dryer ) (continuous Plate drying Equipment )
is a kind of high efficiency conducting and continuous drying equipment. Its unique structure and operating principle provide advantages of high heat efficiency, low energy consumption, less occupying area, simple configuration, easy operation and control as well as good operating environment etc. It is widely used in drying process in the fields of chemical, pharmaceuticals, agricultural chemicals, foodstuff, fodder, process of agricultural and by-products etc., and is well received by various industries. Now there are three big categories, normal pressure, closed and vacuum styles and four specifications of 1200, 1500, 2200 and 2500; and three kinds of constructions A (carbon steel), B(stainless steel for contact parts) and C (on the basis of B to add stainless steel for steam pipes, main shaft and support, and stainless steel linings for cylinder body and top cover). With a drying area of 4 to 180 square meters, now we have hundreds of models of series products and various kinds of auxiliary devices available to meet requirements of various products.
It is an innovation horizontal batch-type vacuum dryer . The moister of wet material will be evaporated by heat transmission. The stirrer with squeegee will remove material on hot surface and move in the container to form cycle flow. The evaporated moisture will be pumped by vacuum pump.
Wet materials are fed continuously to the top drying layer in the dryer. They will be turned and stirred continuously by harrows when the harrow's arm rotates, the material flows through the surface of the drying plate along the exponential helical line. On the small drying plate the material will be moved to its exterior edge and drop down to the exterior edge of the large drying plate underneath, and will then be moved inward and drop down from its central hole to the small drying plate on the next layer. Both small and large drying plates are arranged alternately so as materials can go through the whole dryer continuously. The heating media, which could be saturated steam, hot water or thermal oil will be led into hollow drying plates from one end to other end of the dryer. The dried product will drop from the last layer of the drying plate to the bottom layer of the smell body, and will be moved by harrows to the discharge port. The moisture exhausts from materials and will be removed from the moist discharge port on the top cover, or sucked out by the vacuum pump on the top cover for vacuum-type plate dryer. The dried product discharged from the bottom layer can be packed directly. The drying capability can be raised up if equipped with supplementary devices such as finned heater, condenser for solvent recovery, bag dust filter, return and mix mechanism for dried materials and suction fan etc. solvent in those paste state and heat sensitive materials can be easily recovered, and thermal decomposition and reaction can be also carried out.
80 square meters, now we have hundreds of models of series products and various kinds of auxiliary devices available to meet requirements of various products.
|Type||Diameter(mm)||Height(mm)||Drying Area(m2)||Power (kw)|
1. Easy control,wide application
(1). Through adjusting the thickness of materials layer,rotating speed of main shaft,the number of harrow’s arm,harrow’s model and size,the best drying process can be set.
(2) Each layer of drying plate can be fed with hot or cold medium individually to heat or cold materials and make temperature control accurate and easy.
(3) Material’s residence time can be adjusted accurately.
(4) Single flowing direction of materials without return flowing and mixing,uniform drying and stable quality,no remixing is required.
2. Easy and simple operation
(1) Easy to switch on and off
(2) After material feeding stops,harrows can quickly discharge material out of the dryer.
(3) Through a large viewing lens,detailed cleaning and check up can be done inside of the machine.
3. Low energy consumption
(1) Thin Layer of material,low speed of main shaft,small power and energy required for conveying system of material.
(2) Dry by conducting heat so it has high heating efficiency and low energy consumption.
4. Good operation environment,solvent can be recovery and powder discharging meets the emission regulation.
(1)Normal pressure type:As air flow keeps low speed inside the equipment and moisture density is much higher in upper part that lower part,dust is not able to float up.Therefore,no dust powder mixes with exhausted air discharge from the outlet at the top.
(2)Closed type:Equipment with solvent recovery device that can recycle organic solvent easily from moist-carrier gas in closed circulation for those subject to burning,explosion and oxidation,and poisonous materials in order for safe operation.Especially suitable for drying of flammable,explosive and poisonous material.
(3)Vacuum type:This model is particularly suitable for drying heat sensitive material since the drying process is under the vacuum state.
5.Easy installation and small space occupancy.
(1)The machine is delivered in an integral,it is easy to install by hoist only.
(2)Due to the multi-layer design,the drying capacity is large with a small space occupancy.
