TECHNICAL PROPOSAL
" Preferences intensified drying vegetables fruit and low productivity "

1.Assignment. The units are intended for use on farms and small power plants. 2.Targets 1.Zapolnit relative vacuum in the market drying equipment for farms. 2.Establishing obborudovaniya small size, power, and, accordingly, relatively low cost. 3.Sozdanie equipment for the product is much higher quality through the use of intensified methods of drying compared with the classical convective methods. Decrease drying time and decrease the residual moisture of the product significantly (several times) decreases the loss of valuable substances (money!) and increases the shelf life. 3. Methods of drying. 1.Iz a wide range of methods intensified drying materials: 1) Drying in a fluidized bed 2) Spray Drying 3) Air-drying 4) IR-dryer 5) high frequency (UHF) drying 6) Vacuum drying 7) Freeze-drying 8), etc. choose the following methods: 1) Drying in a fluidized bed 2) IR-dryer. 2.Prichiny choice: 1) These methods are universal for different products 2) These methods are simple and small dimensions Construction Equipment 3) The equipment can be developed quickly enough. 4.HARAKTERISTIKA PLANTS. Name of indicators Installing the fluidized bed dryer IR Product 1) Grain, 1) Grain Seeds, Seeds Fruits, vegetables, Vegetables, fruits Berries, 2) Flour Mushroom Pasta, 2) Waste Bread canned biscuits production of yeast 3) Frying Cookies Peanut 3) Meat, Fish, Sausage Performance on raw material Carrot Carrot (Vlazh. 85% - 10%) (Vlazh. 85% - 10%) 8.3 - 42 kg / hr 33 kg / h Onion 10 - 50 kg / h Performance Product Carrot Carrot Humidity. 10% humidity. 10% 1.4 - 7 kg / h 5.5 kg / h Installed Power, kW 75.0 36.0 Energy Source El.napryazhenie El.napryazhenie 380 V, 50 Hz, 220 V, 50 Hz Duration drying 45 min - Carrots 3:00 - Carrots 22 minutes - onions 1.5 hours - Cabbage 5.ISHODNYE data for the calculation. The initial data for calculating the characteristics of plants used the experimental data described in the book, "Drying food plant materials, "GK Filonenko and others," Food Industry ", M, 1971 6. "IR-dryer" Radiation generators: 1) reflector lamps of AP-1 (127V, 500 watts) AP-2 (127V, 250 watts) AP-3 (220, 500 W) 2) quartz halogen spotlights KG220-1000 (1 kW) Lifespan - 5000 hours Wavelength max. radiation (80%) - 1 ... 2 mm Design setting "IR-dryer," we consider the 2 options: 1) Automatic 2) primitive. 6.1. Automatic IR dryer " 1) Area (working) of the grid 10 sq.m. (1 m * 10 m) 2) The load on the grid of 10 kg / m? (Carrot) 3) Energy consumption for drying 1 kg of raw materials 1.8 kWh / kg 4) Performance of carrots (raw) with humidity. 85% to 10% of 100 kg in 3 hours or 33 kg / h 5) Installed power 36 kW 6) Schedule: DRY FRUITS AND VEGETABLES 7) Staff - 1 person. 8) The closest analogue - oven PIC-8 (bread) Bagels, carrots and sticks - 150 ... 400 kg / h N = 135 kW 9) Weight = 7 m 10) Automation: a) 2 zone management process: - Thermostat - Timers b) 5 drives: - Compressor cooling - Conveyor - Fan - Frame with lamps 1 (growth - lowering) - Frame with lamps 2 (growth - lowering) c) The release of the product - automatically d) Loading of raw material - either automatic feeder - Either manually DRY FRUITS AND VEGETABLES - The need for the cooling system must decide at the stage of detailed design. - Under the grid can be installed electric heaters (heating elements) to enhance the capacity of the installation (turning it into a baking oven) - The walls inside must have a mirror finish. 6.2. Primitive IR dryer " DRY FRUITS AND VEGETABLES N = 36 kW Q = 33 kg / hour of raw carrots - Dryer can close the mirror (inside) walls. 7. Dryer "fluidized bed" 1) Effective area S = 0.125 ... 0.625 m 2) The flow velocity v = 1 ... 5 m / sec 3) The performance of raw onions: Q = 10.2 ... 51 kg / h Yield of dry onion 2 ... 10 kg / h 4) Installed power: - Feeder load 0.5 kW - Unloading feeder 0.5 kW - Fan 5.5 kW - Heaters: SFD-25 \ 3T 5.22 kW SFD-25 \ 3T 5.22 kW SFD-25 \ 3T 5.22 kW Total: 74.0 kW 5) Maximum temperature of 130 C 6) Air flow 2250 m? / h Structural scheme of the dryer: DRY FRUITS AND VEGETABLES In the absence of the Customer's electric power capacity, as a generator Heat can be applied steam heaters and heat on liquid fuel.
