Description
Technical field
The present invention relates to a kind of vacuum freezing drying device, especially a kind of vacuum freeze drier that is used for tea-drying.
Background technology
Existing tea-leaf withering machine nearly all is a heat baking drying machine, because heat baking drying machine dry tealeaves under normal pressure, high temperature (60～90 ℃) state, tealeaves is in the hot blast and is heated, and a part of organic substance continues oxidation takes place under heating status in the tealeaves, consumes a part of nutriment; Chlorophyll also at high temperature is decomposed destruction and causes tealeaves to darken; Also some leaves with hot blast original aroma substance in the tealeaves.And Vacuum Freezing ﹠ Drying Technology is when dry tealeaves, the temperature of tealeaves remains at below-16 ℃, because the tealeaves temperature is low, chlorophyll changes hardly, the green kingfisher of color and luster and anti-Tibetan, original nutrient contents, various organic substance lose hardly in fragrance and the tealeaves, uniform drying, and water content can be low to moderate below 3%; Firmly be spongiform porous behind the product drying owing on hold before the moisture drying simultaneously, the rehydration of product is good, the easy stripping of content when making tea.Tealeaves through vacuum freeze drying can make the Tea Industry quality improve one to two grade on the traditional handicraft basis.
Generally speaking, when to be dried, its moisture content is about below 30% from collecting for tealeaves, and traditional vacuum freeze drier is to be that about 90% tealeaves is designed by water content, this makes that traditional vacuum freeze drier design is complicated, and structure is huge, and energy consumption is higher.Thereby numerous tea growers and Tea Production merchant can't bear its high equipment investment and operating cost, so the vacuum freeze drier of this quasi-tradition can only use as research equipment in the laboratory, can't apply on a large scale.
The drying box of existing vacuum freezing drying device and radial section shape mainly contain three kinds: the one, and circular, it is believed that generally circular drying box manufacturing is easier to, consumptive material is few, it is believed that generally its shortcoming is that unserviceable space is more, both sides particularly, the 2nd, square, square drying box is made relative difficult, but consumptive material is many, advantage is to have made full use of the space, the 3rd, bell, the manufacturing of this drying box is more difficult than square going back, the few's employing in the present application.
Summary of the invention
Technical problem to be solved by this invention provides a kind of cabinet of novel tea vacuum freeze dryer, by improving this critical piece as tea vacuum freeze dryer, so that whole drying device compact conformation, reduce cost, be suitable between numerous tea growers and Tea Production merchant, promoting the use of.
For solving above technical problem, the cabinet of tea vacuum freeze dryer of the present invention comprises drying box, the radiation heating board component, the cold-trap assembly, be installed on the drying box hermatic door of drying box end, the second heating medium inlet pipe that the radiation heating board component is connected with the cabinet outside, go out pipe, the cold-producing medium inlet pipe that the cold-trap assembly is connected with the cabinet outside, go out to manage the vacuum-pumping tube that has on the drying box, drainpipe; The concrete radial section that is described drying box that improves is circle; Described cabinet also comprises the bearing support that is fixed on the drying box inwall; The radiation heating board component is installed in the middle of the drying box by the axial level of bearing support; The cold-trap assembly places among the bearing support outside and the formed circular arc of the drying box inwall space, and is fixed on the circular arc inwall of drying box.
As another kind of improvement the of the present invention, the width of described radiation heating board component is 30%～60% of a drying box radial section diameter.
As another kind of improvement the of the present invention, described radiation heating board component is made up of two-layer above radiant heating panel.
As another kind of improvement the of the present invention, be positioned at two gap locations between radiant heating panel, apart from the place of next piece radiant heating panel surface distance 0.5～2cm, device has the guide rail that is fixed on the bearing support inboard; Material disc is placed on the described guide rail.
As another kind of improvement the of the present invention, the antiradiation board component is installed in the outside of bearing support.
As another kind of improvement the of the present invention, described drying box hermatic door (14) is two fans, is installed in the two ends of drying box respectively.
After adopting such structure, make the interior space availability ratio of drying box improve greatly, and reduced and made the material that uses, reduced manufacturing cost.The more important thing is to make tea vacuum freeze dryer be convenient to operation, and be suitable for the tea-drying industry, reduced the operating cost of equipment significantly the low characteristics of prefabricated tealeaves water content.
Description of drawings
The present invention is described in further detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structural representation of the radial section of the embodiment of the invention.
Fig. 2 is the axial slices structural representation that the embodiment of the invention does not contain the cold-trap assembly.
Fig. 3 is the axial slices structural representation that the embodiment of the invention does not contain the radiation heating board component.
Fig. 4 is the structural representation of another embodiment of the present invention.
The specific embodiment
As shown in Figure 1 and Figure 2, the cabinet of this tea vacuum freeze dryer, comprise drying box 5, radiation heating board component 1, cold-trap assembly 4 is installed in the drying box hermatic door 14 of drying box end, the second heating medium inlet pipe 8 that radiation heating board component 1 is connected with the cabinet outside and go out pipe 9, the cold-producing medium inlet pipe 10 that the cold-trap assembly is connected with the cabinet outside and go out pipe 11, vacuum-pumping tube 13 that has on the drying box 5 and drainpipe 12; The radial section of drying box 5 is circular; Described cabinet also comprises the bearing support 2 that is fixed on drying box 5 inwalls, and this bearing support is divided into cabinet 3 arc spaces on radial section; Radiation heating board component 1 is installed on the medium position of drying box 5 by bearing support 2 axial levels; Cold-trap assembly 4 places among bearing support 2 outsides and formed two the circular arc spaces of drying box 5 inwalls, and is fixed on the circular arc inwall of drying box 5.Adopt this arrangement mounting structure, make and the compact conformation of cabinet improved its space availability ratio greatly.
The width that Fig. 1 shows radiation heating board component 1 of the present invention is 30%～60% of a drying box radial section diameter, and this radiation heating board component is by the multilayer radiant heating panel.Can utilize the inboard space of circular arc up and down that forms with the box body inwall of bearing support so more fully.
