The three processes are continuously carried out. The moisture (solvent) inside the material penetrates, evaporates, and drains from time to time to the surface. The material reaches the goal of drying in a short time. The equipment mainly consists of barrel and frame, size hollow heating plate, main shaft, cross arm and spur leaf, disc feeder, blanking plate and finished product outlet, exhaust gas inlet, heat carrier inlet and outlet pipe, Check the door, worm gear reducer, continuously variable transmission and motor. The main component of the equipment is a hollow heating plate. The hollow section is welded with a baffle plate to strengthen it. It not only increases the stiffness and strength, but also improves the heat transfer effect, and it has the advantage of high utilization of conduction drying heat energy. Continuous vacuum dryer The substance to be dried is rapidly frozen at a low temperature, and the freeze-drying is a technique for drying using the principle of sublimation. Then, under a suitable vacuum environment, the frozen water molecules are directly sublimated into a process in which water vapor escapes. The product obtained by freeze-drying is called lyophilization. This process is called lyophilization and the sublimation process does not cause concentration due to dehydration, preventing the Water vapor produces side effects such as foam and oxidation. The dry substance is dry porous sponge, the volume is basically the same, easily soluble in water and restore the original state. It prevents physicochemical and biological degeneration of dry substances to a maximum extent. The substance is always at a low temperature (freezing state) before it is dried, while the ice crystals are evenly distributed in the substance. Generally, the upper layers are heated by low-pressure saturated steam or hot water, hot oil in series, parallel or serial and parallel input heating, and each layer of the heating plate has a heat carrier inlet and outlet pipe. Control the temperature of each layer; and in the bottom two layers of cooling water, to reduce the product temperature, heat recovery, to ensure quality. The heating plate is fixed on the cylinder frame with a certain distance and is placed horizontally. The cross arm frame is installed on each floor. The upper and lower two layers are staggered at an angle of 45° and are fixed on the center spindle. The worm gear reducer and continuously variable transmission are used. Driven by a motor, etc., slowly rotates at 0.6 to 3.7 r/min. Each arm rack is equipped with multiple detachable jaw plow blades or flat screeds arranged in a equidistant manner. The hinge adopts the hinge and the reed swing structure so that the bottom edge floats on the surface of the disk, and the angle of the loaf can be arbitrarily adjusted according to the properties of the material to ensure that the material continuously advances on the surface of the disk. Under the mechanical action of the rotary lobe, the dried material is continuously supplied from the top disc feeder to the inner ring surface of the uppermost first layer of the small heating plate in the apparatus. While tumbling and stirring, moving continuously from the inside to the outside, the surface of the disk is covered with zigzag and heated and dried. Then the material is dropped from the outer edge to the underside of the second large heating plate. Under the action of the loquat leaves, it moves from the outside to the inside and moves to the inner edge in order, and falls on the inner surface of the third heating plate. By analogy, the material is moved layer by layer from top to bottom and continuously heated and dried. The final dry material falls on the lower plate, and the evaporated moisture is naturally discharged from the upper outlet by mixing with the exhaust gas inside the equipment. Scrape from the loquat leaves to the discharge port at the bottom for continuous discharge to obtain qualified dry waste. According to the product performance, drying requirements and the amount of processing, the plate dryer adopts a series of measures such as stepless speed regulation of the spindle, manual adjustment of the height of the disc feeder adjustment sleeve, control of the temperature distribution of the heating plate in each layer, and cooling and cooling in the final stage. Plate dryer superior performance. Vacuum Dryer - Mechanical Use Microwave vacuum dryer Then, under vacuum conditions, the solid water (ice) in the article is directly sublimated into water vapor. The vacuum dryer is composed of a refrigeration system, a vacuum system, a heating system, and an electrical instrument control system. The main components are drying ovens, condensers, refrigeration units, vacuum pumps, heating/cooling units, etc. The principle of operation is to freeze the items to be dried below the triple point temperature. Remove from the article and allow the article to dry. After the material is pre-treated, it is sent to a quick-freezing chamber for freezing, then sent to a drying warehouse for sublimation and dehydration, and then packaged in a post-processing workshop. The vacuum system establishes a low pressure condition for the sublimation drying chamber, the heating system provides the sublimation latent heat to the material, and the refrigeration system provides the required coldness to the cold trap and the drying chamber. The material is heated evenly; the trap is trapped efficiently and the equipment is heated with high efficiency radiation. It can realize rapid defrosting; adopts high-efficiency vacuum unit and can realize oil-water separation; adopts parallel centralized refrigeration system, multi-channel on-demand cooling, stable working conditions, and favorable energy-saving; artificial intelligence control is adopted to achieve high control accuracy and convenient operation. The quality requirements for the freeze-dried products are the same in terms of biological activity, uniform color appearance, full shape, firm structure, fast dissolution rate, and low residual moisture. To obtain high-quality products, there should be a more comprehensive solution to the theory and process of lyophilization. The tank body is rotated slowly. The lyophilization vacuum drying process includes pre-freezing, sublimation and re-freeze drying in three stages. Reasonably and effectively shortening the cycle of lyophilization has obvious economic value in industrial production. The vacuum dryer passes a heat energy source (such as hot water, low pressure steam or heat transfer oil) into the sealed interlayer and heat is transferred from the inner shell to the material to be dried. Driven by power. The materials in the tank are continuously mixed so as to achieve the purpose of strengthening and drying the material in a vacuum state. The atmospheric pressure drops to saturate the water (solvent) on the surface of the material and evaporate, and is discharged by the vacuum pump in time.
