Abstract
The utility model provides an improvement of a vacuum drier for manufacturing vacuum drying type sweet potato slices. A pressure tank is arranged in the vacuum drier. The improvement is characterized in that a circular groove which surrounds the outer wall of the pressure tank in a multiple-ring spiral shape is formed in the outer wall of the pressure tank, a heat supplying coil pipe is contained in the circular groove, an inlet and an outlet of the heat supplying coil pipe are connected with a heat conductance oil heat supply device, and a heat insulation sealing layer made of heat insulation materials is embedded in the annular groove to seal the heat supplying coil pipe in the circular groove. According to the improvement, the heat supplying coil pipe is contained in the circular groove formed in the outer wall of the pressure tank, the heat conductance distance between the heat supplying coil pipe and the inner wall of the pressure tank is reduced, the speed of heat led from the heat supplying coil pipe to the interior of the pressure tank is quickened, the circular groove is sealed by the heat insulation sealing layer so as to enable the heat of the heat supplying coil pipe not to be sent to the outside to be wasted, therefore, the temperature rising speed of the pressure tank is quickened, and the production efficiency is improved.
Description
Technical field
The utility model belongs to a kind of food processing machinery, relates in particular to a kind of structure of vacuum drier.
Background technology
Vacuum drying type dried sweet potato is to carry out vacuum drying and obtain the dried sweet potato of crisp-fried taste put into vacuum drier through additive modulation, boiling, quick-frozen, pretreated ground of the technique sugar-preserved gourd such as thaw.
first the ground sugar-preserved gourd is carried out pretreatment and predrying, (this processing can make the ground sugar-preserved gourd reach a state that is easy to deformation to be dried to moisture and to be 20%～25%, and this one-phase is also the process of a dehydration, saves vacuum drying energy consumption of later stage, after this one-phase drying, what and expansion effect of water content has direct relation), then, the ground sugar-preserved gourd is placed in pressurized tank, the pressurization of heating after sealing, atmospheric pressure 0.2-0.3Mpa outside the tank internal pressure rises to higher than Bulking tank (makes between Bulking tank and vacuum system and produces a pressure differential, this pressure differential is the power of moisture flash evapn in material), when temperature reaches 120-130 ℃, (this temperature makes material place and an overheated and softening state, make material be easy to deformation, be convenient to expanded), stagnate 0-15min (making the temperature on material surface reach the temperature that sets), open rapidly subsequently the relief valve that connects Bulking tank and vacuum tank (vacuum tank vacuumizes in advance), due to moment step-down in pressurized tank, make material internal moisture flash evapn, (material after predrying itself is in the state of a drying shrinkage to cause the pachyrhizus tissue to form uniform alveolate texture, because moment is opened relief valve, moisture moment in material is escaped to the vacuum system direction, the material that drives simultaneously drying shrinkage swells, when having completed the material dewatering process, make material reach a fluffy state).Keep vacuum state (0.098MPa), be to keep thermal dehydration a period of time under 60-80 ℃ of condition in temperature, until reach required water content, (this process can further make material dewatering to stopped heating, material moisture is further descended), make pressurized tank abolish vacuum (this process can make the material after expanded cooling fast, is convenient to the product approval of material after expanded) after cooling 30-60min under 10-20 ℃ of condition, take out product and pack, namely obtain dilated product.
Therefore, in vacuum drying, need to repeatedly heat to pressurized tank, therefore need to carry out Quick uniform to pressurized tank and heat to enhance productivity and guarantee the taste that dried sweet potato has had.
The utility model content
The utility model provides a kind of improvement of the vacuum drier for the making of vacuum drying type dried sweet potato, its objective is and solves the shortcoming that prior art exists, and the pressurized tank that is used in the vacuum drier of vacuum drying type dried sweet potato making heats up faster.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of improvement of the vacuum drier for the making of vacuum drying type dried sweet potato, has pressurized tank in vacuum drier, it is characterized in that: the outer wall of pressurized tank is provided with an annular groove that is on a few outer walls that spirally are looped around pressurized tank, accommodating heating coil pipe in annular groove, the import of heating coil pipe and outlet and thermal conductance oil heating plant are connected, and be embedded with the adiabatic confining bed that heat-insulating material makes on annular groove heating coil pipe is sealed in annular groove.
Usefulness of the present utility model is:
The utility model is due in being contained in heating coil pipe the set groove of pressurized tank outer wall, the heat conduction distance of heating coil pipe and pressurized tank inwall is dwindled, the heat of having strengthened heating coil pipe imports the interior speed of pressurized tank, the insulated confining bed sealing of annular groove makes the heat of heating coil pipe can outwards not distribute and waste, these improve the programming rate that has all improved pressurized tank, and the vacuum drying production efficiency of dried sweet potato is improved.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model structure chart;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model is the improvement to a kind of vacuum drier for the making of vacuum drying type dried sweet potato, have pressurized tank 1 in vacuum drier, vacuum drier also has other equipment such as vacuum extractor, shell etc., with this, improves irrelevant therefore no longer description.The outer wall of pressurized tank 1 is provided with an annular groove 10 that is on a few outer walls that spirally are looped around pressurized tank 1, annular groove 10 is altogether around pressurized tank 1 five circles, be isometric helix shape, the interior accommodating heating coil pipe 2 of annular groove 10, the import 21 of heating coil pipe 2 be connected 22 and be connected with thermal conductance oil heating plant 3, heating coil pipe 2 is metal tubes, being embedded with the adiabatic confining bed 4 that heat-insulating material (for example rubber) makes on annular groove 10 is sealed in heating coil pipe 2 in annular groove 10, adiabatic confining bed 4 can be the rubber of a whole piece, be fastened in annular groove 10 isolated outside the distributing of heat.
Like this, while needing to heat up, start thermal conductance oil heating plant 3, deep fat just enters heating coil pipe 2, and the heat overwhelming majority of sending enters in pressurized tank 1 by the outer wall of pressurized tank 1, and cooperation vacuumizes, and makes the dried sweet potato in pressurized tank 1 carry out vacuum drying.Experiment to the vacuum drier of common model shows, owing to improving heating effect, the time of every pot of crisp-fried dried sweet potato product vacuum drying dehydration in drying machine reduced to 70 minutes by 90 minutes, had improved yield in unit time.And the vacuum drying dewatering time reduces, and the appearance luster of product is better.
