The invention provides three special environment-friendly and energy-saving drying machines for finished products formed by food, such as biscuits, milk powder, dried meat and Chinese drug pills, tablets and powder granules formed by traditional Chinese medicine drugs. A second granular material granule food and medicine drying machine which is formed by a clean fuel combustion machine and a granular material drying machine through combination is defined as a second environment-friendly and energy-saving drying machine of three food and medicine environment-friendly and energy-saving drying machines. The second environment-friendly and energy-saving drying machine is suitable for popularization and application of professional production and professional users.

Description

The second environmental protection and energy saving drying machine of food, medicine three kinds of environmental protection and energy saving drying machines

Technical field: division of the present invention provides food, medicine drying machine, especially relates to the second environmental protection and energy saving drying machine of food, medicine three kinds of environmental protection and energy saving drying machines.

Background technology: at present, food as the finished product industries such as pollen, milk powder, biscuit, jerky and medicine as the finished product industries such as tablet, electuary, medicinal powder the modernization drying plant drying machine that uses the mode of heating that adopts except electrical heating be all take heat exchanger burning coal, burn plant faggot transforms by high-pressure boiler the steam that transports or utilize the combustion of fossil fuel such as bavin gasoline, kerosene, coal gas, natural gas the pyrotechnics that produces be converted into high-temperature cleaning air and input drying machine and carry out dry medicine or food.In this course, because steam reaches more than 40% through twice convert fuel energy loss, energy (heat energy) utilization rate of the fossil fuel again changed through heat exchanger also only has about 70%.In addition, in order to solve the environmental air pollution problem that combustion of fossil fuels causes, food and medicine manufacturer must spend writing investment to go to do environmental purification technical equipment, and cumulative production cost is more and more higher according to this, and the profit of corporate earning is just fewer and feweri (low).The present invention is the new equipment in order to solve aforementioned puzzlement manufacturing enterprise's difficult problem and creativity and innovation.

Summary of the invention: in order to realize the environmental protection and energy saving object of food, medicine drying machine, the embodiment that the present invention adopts is: emphasis improves the anti-pollution problem of clean health of the heat source of drying machine, next is the heat utilization rate and the reduction production cost that improve fuel combustion releasing, the focal issues such as recovery waste heat recycling.Specific solving methods has: scheme one, the hydrogen of the clean fuel hydrogen fuel of non-pollution discharge or liquid solid hydrogen fuel is adopted to make main fuel, or employing only has the natural gas of light contamination, fuel made by ethanol (alcohol), coordinate hydrogen, Natural Gas flame projector, Hydrogen fuel combustion device or coordinate fuel liquid combustion machine to use.Lifting gas injection firearm is example, conventional flame projector is by the combustion-supporting burning of natural air, because supplementary combustion oxygen amount is inadequate, burn abundant not, so flame of its ejection takes on a red color and with black smog, now increase a turbocharger or join a comburant oxygen device with the use of, then can stand the cyanic colours flame ejection seen and improve efficiency of combustion, and smoke-free and tasteless, environment protection clean.This improvement project estimates that the clean heat energy that comparable original pulverizing jet and heat exchanger obtain improves more than 40%, and add the Energy-saving of waste heat recovery, both totals can save energy and reach more than 60%.

Detailed description of the invention: concrete structure: comprising key fitment has: gas injection firearm, booster, hydrogen cylinder, wireway, temperature controller, magnetic valve, igniter, flame gas mixing chamber, powder slurry drum mist drying machine, high temperature slurries gas and vapor permeation thick fog pressure spray machine, gas powder separator, nodulizer, shot-like particle drying machine, tablet drying machine, finned comb case waste heat returns device, Split hot bobbin carriage waste-heat recoverer, oxygen cylinder, ethanol liquid combustor, oxygen limitation valve, slurries limitation adder, guide duct.Connection Step is: the gas outlet and the slurries limitation adder discharging opening that connect flame gas mixing chamber at the air entry of the high temperature slurries gas and vapor permeation compression spraying machine of powder slurry spray dryer respectively, the air inlet of flame gas mixing chamber is connected with gas injection firearm bocca, gas injection firearm is first connected with magnetic valve with wireway, then connect hydrogen cylinder, magnetic valve is electrically connected with temperature controller, finally, the dry powder floss hole of powder slurry spray dryer connects gas powder separator, the exhaust outlet connecting fin chip comb case waste-heat recoverer of gas powder separator, the preheated air outlet of finned comb case waste-heat recoverer is connected logical with guide duct with the air inlet of flame gas mixing chamber, the assembly and connection of scheme two basis by scheme one installs additional and exchanges accessory and form, it is characterized in that: powder slurry spray dryer is changed into shot-like particle drying machine, turbocharger is connected to improve the combustion-supporting quantity of air oxygen at gas injection firearm lower body suit, then gas injection firearm etc. are constant by scheme one assembly and connection, but connect Split hot bobbin carriage waste-heat recoverer hypomere at shot-like particle drying machine Waste gas outlet and the shot-like particle that is connected with the epimere air outlet of guide duct and Split hot bobbin carriage waste-heat recoverer, the inlet scoop of drying machine forms the second energy-saving dryer.

Operation principle: environmental protection and energy saving principle of the present invention is, have employed clean burning and join machine use, the heat transfer losses eliminating heat exchanger about reaches the heat-energy losses of 40%.Many heat pipes waste-heat recoverer of all-in-one-piece, the split of the new high-efficiency that have employed recovery waste heat and finned comb case waste-heat recoverer is had to coordinate aforementioned energy-saving dryer to use again, obtain the energy-saving effect of about more than 30% further, both are added and add up to saving energy to reach more than 60%.This is the environmental protection and energy saving general principle of food, medicine three kinds of environmental protection and energy saving drying machines.

Social benefit: due in food, medicine drying field, being applied to of energy-conserving and environment-protective technology is also rarely found at present, as the present invention can promote the use of in oven dry industry, will produce considerable economic benefit and environmental benefit to society.
