Abstract
The utility model relates to a microwave vacuum drying machine belongs to drying equipment technical field. The sealed enclosure that the lateral wall has chamber door (3) is drawn together to this press packed bale, top installation microwave emitter (1) down of box, a side -mounting vacuum pump interface (8) and rotation driving device (6) of box, support horizontal spindle (11) be connected with the rotation driving device transmission in the box, the both ends of main shaft have carousel (9) that link firmly with it respectively, stock column (10) of the peripheral interval distribution hook charging tray (13) of carousel. This microwave vacuum drying equipment combines together microwave technology and vacuum technique, has had microwave drying and vacuum drying's advantage, has overcome the shortcoming that conventional vacuum drying temperature is high, chronic, the energy consumption is big, has the advantage that dry output is high, the processing cost is low to it is dry under low temperature and low pressure, make to be weakened by dry material oxidation reaction because of the oxygen content is low to slow down, thereby guaranteed flavor, outward appearance and the color and luster of material.
Description
Technical field
This utility model relates to a kind of drying machine, especially a kind of microwave vacuum dryer, belongs to food drying equipment technical field.
Background technology
It is the first that the fruit and vegerable yield of China occupies the whole world, but owing to fruits and vegetables process technology is delayed, there are about 25%～30% can not utilize because rotting, cause tremendous economic to lose after adopting every year.The processing capacity of dehydrated vegetables simultaneously only accounts for about the 10% of total output, and the dry products ratio of fruit is lower.According to the applicant understood, current fruit and vegetable dryness major part uses simple hot air drying, and this drying mode not only energy consumption is high, and the product appearance of processing, nutrition, taste are the most undesirable, cause product quality not good enough, and added value is low.
According to physics, under vacuum, material internal moisture is evaporated under low temperature state, can reach the purpose of cold drying.Microwave heating is made by microwave and directly has an effect object, makes the most heated radiant heating pattern inside and outside it, due to need not be by convection current or transmit heat, so firing rate is fast, the thermal efficiency is high, it is short to process the time, material inside and outside homogeneous temperature, therefore the energy is saved, drying efficiency is high, and dry mass is good.But, prior art fails to organically combine microwave with vacuum, because failing the advantage giving full play to microwave drying in fruit fresh vegetables is processed.
Utility model content
The purpose of this utility model is: propose a kind of microwave vacuum dryer organically combined by microwave with vacuum generation technique, so that fruit fresh vegetables is stored after being able to be dried under the situation keeping local flavor, outward appearance and color and luster.
In order to achieve the above object, microwave vacuum dryer of the present utility model includes that sidewall has the containment housing of chamber door (3), microwave emitter (1) down is installed at the top of described casing, vacuum pump interface (8) and rotating driving device (6) are installed in the side of described casing, the horizontal spindle (11) that described casing inner support is in transmission connection with rotating driving device, the two ends of described main shaft are respectively provided with the rotating disk (9) being connected therewith, the stock column (10) of periphery hook spaced apart charging tray (13) of described rotating disk.
When being spread out in charging tray by the material of fresh fruit vegetable etc, after hanging on stock column by suspension hook, closing chamber door, open vacuum pump evacuation, open rotating driving device simultaneously, mainshaft gear drives rotating disk to rotate, naturally volatilization.When reaching the vacuum set, keep negative pressure and open microwave emitter, utilizing microwave that the material with dial movement is dried, reaching to shut down during predetermined moisture content.
Microwave technology is combined by this micro-wave vacuum equipment with vacuum technique, microwave drying and vacuum drying advantage are had both, overcome conventional vacuum baking temperature height, time length, shortcoming that energy consumption is big, there is the advantage that dry yield is high, processing cost is low, and it is dried under low-temp low-pressure, make to be dried material oxidation reaction to weaken slow down because oxygen content is low, thus ensure that the local flavor of material, outward appearance and color and luster.
It is that two row's microwave emitters are installed at the top of described casing along main axis length direction that this utility model further improves, and the controlled end of each microwave emitter connects the microwave power supply of correspondence respectively.
Further, described rotating disk is regular hexagon.

Detailed description of the invention
Embodiment one
As shown in Figure 1 and Figure 2, generally containment housing, wall box has the chamber door 3 of with handles 4 to the microwave vacuum dryer basic structure of the present embodiment.Two rows, often six microwave emitters 1 down of row are installed in the top of casing along main axis length direction, are controlled to launch by corresponding microwave power supply 7 respectively.Vacuum pump interface 8 and the mainshaft gear 6 as rotating driving device are installed in the side of casing.The horizontal spindle 11 that casing inner support and mainshaft gear are in transmission connection, the two ends of this main shaft 11 are respectively provided with the regular hexagon rotating disk 9 being connected therewith, the stock column 10 of the periphery six roots of sensation spaced apart hook charging tray 13 of rotating disk 6.
When being dried, the rotating disk stock column of main shaft both sides hangs the charging tray spreading material respectively, closes chamber door and opens vacuum pump, and drive shaft motor, drives rotating disk to rotate by mainshaft gear.When vacuum reaches setting value, control vacuum pump and keep this vacuum a number of microwave emitter of on-demand unlatching to be dried, and determine drying time according to weight of material and moisture content.It was verified that the drying machine of the present embodiment has a following notable beneficial effect:
1) owing to using the drying mode that combines with vacuum of microwave, therefore have microwave drying and vacuum drying advantage concurrently, overcome conventional vacuum baking temperature height, time length, shortcoming that energy consumption is big；2) driven by rotary disc rotation of disc is used to make dry materials more rapidly, uniformly；
3) 12 microwave emitters are controlled respectively by 12 air switches, and different combinations of launching can be selected as required to meet different power and dry requirement.
Claims (3)
1. a microwave vacuum dryer, there is the containment housing of chamber door (3) including sidewall, microwave emitter (1) down is installed at the top of described casing, it is characterized in that: vacuum pump interface (8) and rotating driving device (6) are installed in the side of described casing, the horizontal spindle (11) that described casing inner support is in transmission connection with rotating driving device, the two ends of described main shaft are respectively provided with the rotating disk (9) being connected therewith, the stock column (10) of periphery hook spaced apart charging tray (13) of described rotating disk.
