Description
Technical field
This patent relates to food drying energy-saving equipment, is specially a kind of double-source heat pump vermicelli drying dehumidification recuperation of heat unit, is applicable to the drying of slice based food or other product dryings.
Background technology
China is the cradle of vermicelli technology, has the history of more than 2000 year, in history the multiplex manual production of vermicelli, and daylight airing, yields poorly, of poor quality.Until the twenties in 20th century starts just to adopt mechanization production.Vermicelli be add salt by wheat flour, noodles that alkali, water are made, after loft dried, cut into the dried noodles of certain length.It is a most important ring during vermicelli are produced that vermicelli are dried, and baking room, as controlled bad easy generation noodle rupture or turning sour, causes vermicelli defective work.Thus select rational noodle drying process and thermal source control mode extremely important.Current vermicelli drying room can be divided into low temperature drying room, middle temperature drying room, high temperature drying room by bake out temperature, and high temperature drying room controls because of difficulty or ease, and thus the most common is at present low temperature drying room and middle temperature drying room.Cableway-type drying room and tunnel type drying room can be divided into again by drying room structure.The heat source way that current vermicelli are dried is mainly from several as follows: natural gas boiler, coal-burning boiler, bavin boiler, oil burning boiler, electric boiler.Heat transfer type in drying room has warm-air pipe heat radiation, heat-conducting oil pipes heat radiation, hot-water line heat radiation.The heat source way energy consumption cost of electric boiler is the highest, and operating cost is generally 2-4 times of other heat source way, general little employing.The raw material problem of oil burning boiler and bavin boiler and firewood too high because of fuel cost respectively again, adopts also relatively less.Because the unit price of coal is relatively low, the heat source way of current vermicelli oven dry more than 90% all adopts coal-burning boiler, also has small part to adopt natural gas boiler.How vermicelli are at drying course in economize energy expense simultaneously of improving the quality of products, and are difficult problems for vermicelli industry always.The heat source way of traditional burning type such as combustion gas, fire coal is adopted to expose all deficiencies gradually: the mode 1, obtaining thermal source by burning coal, combustion gas, burning bavin etc., consume a large amount of primary energy, effectively utilizing of the energy is low, heat energy is wasted greatly, produce CO2 isothermal chamber gas simultaneously, be the arch-criminal of greenhouse effects, generation nitride and sulfide cause the disaster such as haze, acid rain.The firing equipments such as 2, traditional coal-burning boiler, gas fired-boiler, electric boiler, have strict instructions for use, boiler plant all needs annual test every year.The service life of equipment is relatively short in addition, and general 3-6 replacing service life once, causes equipment overlapping investment.3, input drying room after the thermal source produced by modes such as fire coal, combustion gas, burning materials carries out secondary heat exchange by conduction oil or recirculated water to use, the stability of drying room temperature derives from the stability of thermal source.Heat source way that is coal-fired and burning material is very large by the rate of fuel combustion, and the temperature fluctuation of thermal source directly causes the warm and humid control difficulty of drying room to strengthen, and in drying course, temperature contrast is comparatively large, and vermicelli oven dry quality stability is poor.The crisp bar that noodles stoving easily produces and the defective work such as to turn sour.The labour intensity of operating personnel is quite large simultaneously.4, all need hydrofuge in vermicelli drying course, traditional hydrofuge mode be by the damp-heat air in drying room by outside the direct discharge chamber of wet-emitting blower, cause a large amount of heat loss, add the energy consumption of vermicelli baking needed.5, in drying course, without the consumption primary energy of cut-off, cause resource transition to exploit, some place is when coal resources anxiety, and felling mountain forest causes landslide, causes significant impact to the productive life of people.The drying plants such as traditional fire coal, burning material to be not suitable with the policy of national sustainable development, need reliable energy-conserving product to substitute in drying course.
