Description

A kind of Semen Castaneae acanthosphere is dried removing device
Technical field
The present invention relates to a kind of Semen Castaneae acanthosphere and be dried removing device.
Background technology
Semen Castaneae is the arbor in Fagaceae Castanea or shrub general name, about 7-9 kind.Primary in ground, temperate zone, the Northern Hemisphere District, major part kind chesnut be all the deciduous tree that 20-40 rice is high, only minority be shrub.Various chesnuts fruit all may be used With edible;Dan Ye, oval or long ellipticity, 10-30 centimeter length, 4-10 centimetre wide, and there is setiform tooth at edge.Hermaphroditism, male Flower is upright catkin, and independent or several of female flower is born in involucre.Nut contains in close raw spine ground involucre, thus Semen Castaneae Involucre also challenges chestnut acanthosphere, a diameter of 5-11 centimetre of Chinese chestnut involucre, has 1-7 nut in an involucre.
In order to obtain the nut in involucre, present stage mainly uses the method for natural drying manually to shell, but natural drying The method the most manually shelled not only efficiency is low, and is unfavorable for very much the development of world chestnut industry.If able to provide a kind of mental retardation Consumption and the high mechanization Semen Castaneae acanthosphere of efficiency are dried removing device, then the industrialized development for Semen Castaneae will benefit, and energy Effectively alleviate human labour, it is achieved energy-saving and emission-reduction.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art exactly, it is provided that a kind of heating by heat-pump-type Make moisture in Chinese chestnut involucre discharge with the form of aqueous water, energy loss can be reduced in dry run to greatest extent and remove shell side The simple Semen Castaneae acanthosphere of formula is dried removing device.
For overcoming the deficiencies in the prior art, the present invention takes techniques below scheme:
A kind of Semen Castaneae acanthosphere is dried removing device, goes along with sb. to guard him including insulation, it is characterised in that;Interior composition dry environment is gone along with sb. to guard him in insulation, Wherein there is water tank, inject water logging in water tank and do not have spiral coil A therein and spiral coil B;Compressor A, spiral coil A, capillary In pipe A, refrigeration air-conditioner, machine and associated conduit constitute A group heat pump cycle dehumidification system;Machine in cooling/heating air conditioner outer machine, cooling/heating air conditioner, Capillary tube B, spiral coil B and associated conduit constitute B group heat pump cycle heating system;A system realize insulation go along with sb. to guard him interior cooling and The condensate drainage of vaporous water, and by the heat storage of cooling and vaporous water condensation release in water tank;B system realizes insulation and goes along with sb. to guard him In moisture vaporization is gone along with sb. to guard him to insulation in interior intensification and Semen Castaneae, and absorb the heat that A system is stored in water tank;AB system replaces work Make to realize insulation to go along with sb. to guard him the evaporation of interior Semen Castaneae moisture, condense and discharge, and in water tank, the storage of heat utilizes;In heat preservation maintenance It is provided with the sieve aperture rotating cylinder holding Chinese chestnut involucre, is disposed with ribbon in it, below sieve aperture rotating cylinder, is provided with vibratory conveyer, vibrating transportation The blanking port of device connects Castanea mollissima Nut receiving hopper, and vibratory conveyer blanking port connects hair-dryer through blowing bucket.
In described refrigeration air-conditioner, machine connects drain pipe, it is simple to the discharge of condensed water.
Described water tank is external attemperater or built-in non-attemperater.
During equipment work, first by B group heat pump cycle heating system, interior Semen Castaneae is gone along with sb. to guard him in insulation and heat, now plate In moisture in chestnut can gasify due to heating to insulation and goes along with sb. to guard him, in Semen Castaneae, needed for moisture vaporization, energy major part derives from water tank The heat of middle storage, is realized with the water heat exchange in water tank by spiral coil B;Then A group heat pump cycle dehumidification system is restarted, Now insulation is gone along with sb. to guard him interior saturated vaporous water and can be condensate in due to cooling in refrigeration air-conditioner on machine, drain pipe discharge, it is achieved Being dried of interior Semen Castaneae is gone along with sb. to guard him in insulation, and the heat of vaporous water condensation release is stored up with the water heat exchange in water tank again by spiral coil A Exist in water tank.AB system alternation realizes insulation and goes along with sb. to guard him the evaporation of interior Semen Castaneae moisture, condenses and discharge, and heat in water tank The storage of amount utilizes, and owing to being heat pump work, its Energy Efficiency Ratio is up to more than 3.
Chinese chestnut involucre adding sieve aperture rotating cylinder, controls sieve aperture rotating cylinder positive and negative alternate and rotate, wherein ribbon not only can stir, turn over Dynamic Chinese chestnut involucre, and the axially-movable of Chinese chestnut involucre left and right can be realized, add quick, efficient, the low energy consumption dehydration of Chinese chestnut involucre, make Castanea mollissima Nut is particularly easy in Chinese chestnut involucre abjection, falls on vibratory conveyer, it is achieved the dry of Chinese chestnut involucre shells.
Chinese chestnut involucre is dried a small amount of burr produced during shelling and is blown away through blowing bucket by hair-dryer, obtains more clean Castanea mollissima Nut.
Compared with prior art, beneficial effects of the present invention also resides in:
1, in Semen Castaneae, the discharge of moisture is entirely the form discharge with condensed water, does not has other dehumidifying, heat extraction mouth, due to vaporous water Enthalpy be significantly larger than condensed water and temperature is higher.Therefore, compared with existing gaseous state dehumidifying drying mode, energy loss is greatly Reduce, it is possible to achieve refrigerated dehumidification heat zero-emission.
2, inject water logging in water tank and do not have spiral coil A therein and spiral coil B, be evaporated to insulation at Semen Castaneae moisture and go along with sb. to guard him The heat stored in water tank can be discharged time interior, can with the heat of absorption condensation release also when the condensation of interior vaporous water is gone along with sb. to guard him in insulation It is stored in water tank, it is achieved the storage of moisture evaporation and condenser heat uses, and reduces energy consumption for drying to greatest extent.
3, water tank and external environment atmospheric heat can be carried out cascade evaporation absorption when intensification is gone along with sb. to guard him in insulation, then input insulation Going along with sb. to guard him interior release, promoting to heat up is dried, and be particularly suitable for Cold Winter heats dry cycle.
4, water tank is in addition to Collaborative Control accumulation of heat, controlling thermal output buffering, heat accumulation function, goes along with sb. to guard him interior temperature height when insulation simultaneously When water tank temperature, tank outer wall can absorb heat and make moisture in gas phase separate out discharge, environmental dehumidification in promoting;When going along with sb. to guard him, interior temperature is low When water tank temperature, tank outer wall meeting heat release makes to go along with sb. to guard him interior environment and is easier to heat up, and makes to go along with sb. to guard him interior environment and can be brought rapidly up promoting Semen Castaneae is dried.
The sieve aperture rotating cylinder of built-in ribbon shells extremely simple ingenious.
