Accordingly, the following description is to be construed as broadly known to those skilled in the art and not as limiting the utility model.

It is noted that relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.

The utility model is more particularly described by way of example in the following paragraphs with reference to the drawings. The advantages and features of the present utility model will become more apparent from the following description. It should be noted that the drawings are in a very simplified form and are all to a non-precise scale, merely for convenience and clarity in aiding in the description of embodiments of the utility model.

The present embodiment provides a screw vibration dryer including: vibration base 1, discharging pipe 3, inlet pipe 7 and spiral shell bucket. The vibration base 1 is used for providing vibration power; the feeding pipe 7 and the discharging pipe 3 are used for feeding materials and outputting the materials. The screw barrel is used for transporting materials inside the screw vibration dryer.

The spiral barrel comprises an inner spiral barrel 8 and an outer spiral barrel 5, wherein the input end of the inner spiral barrel 8 is connected with the feeding pipe 7, and the output end of the inner spiral barrel 8 is connected with the input end of the outer spiral barrel 5; the output end of the outer spiral barrel 5 is connected with the discharging pipe 3; when the material enters from the feeding pipe 7, the material will first arrive at the inner spiral barrel 8, and under the action of the vibration force provided by the vibration base 1, the material is driven to vibrate and move along the set direction in the inner spiral barrel 8, so as to be output to the outer spiral barrel 5, and similarly, the outer spiral barrel 5 vibrates under the action of the vibration force provided by the vibration base 1, so that the material can vibrate and move along the set direction until being output to the discharging pipe 3, and is discharged.

In order to achieve the above purpose, the screw barrel, the discharging pipe 3 and the feeding pipe 7 are all required to be installed on the vibration base 1 to form a sealed space. The inner spiral barrel 8 is arranged around the feeding pipe 7, and the outer spiral barrel 5 is arranged around the inner spiral barrel 8, so that space can be saved, and space utilization rate is improved.

Further, the helical vibration dryer proposed in the present embodiment further includes a bridge 6, and the bridge 6 connects the outer screw tub 5 and the inner screw tub 8.

Specifically, referring to fig. 2, the feeding pipe 7 is vertically disposed in the spiral barrel, the lower end of the feeding pipe is connected with the inner spiral barrel 8, the outer spiral barrel 5 and the inner spiral barrel 8 are connected through a bridge 6, and after the frozen material moves from the feeding pipe 7 to the inner spiral barrel 8 through the bridge 6, the frozen material moves to the outer spiral barrel 5 through the bridge 6, so that the next drying operation can be performed.

Furthermore, the screw barrel temperature is controllable. Specifically, the temperature of the inner part and the outer part of the spiral barrel can be controlled, and in the process of drying materials, as the materials are frozen in advance, a large amount of ice in the frozen materials can sublimate in the drying process, the temperature is not more than the lowest eutectic point, and the temperature of the spiral barrel is usually controlled to be +/-10 ℃ in the stage.

The moisture removed by the material in the re-drying stage as frozen product is combined moisture, and the air pressure of the water vapor is reduced to different degrees at the moment, so that the drying speed is obviously reduced. On the premise of ensuring the product quality, the temperature of the spiral barrel should be properly increased in the stage so as to be beneficial to the evaporation of water.

The actual operation should be adjusted to the desired temperature until the material suitable for freezing has reached dryness.

Further, the screw vibration dryer further comprises a housing 4 and a bellows 2. The corrugated pipe 2 is circumferentially arranged around the vibration base 1; the shell 4 is sleeved on the corrugated pipe 2 and the vibration base 1 to form a sealed space.

Specifically, referring to fig. 2, in this embodiment, the casing 4 is connected to the bottom of the vibration base 1, and surrounds the vibration base 1, the bellows 2, the discharging pipe 3, and the screw barrel in an arch shape, and the feeding pipe 7 is welded to the casing 4, connected to the screw barrel, and disposed above the bellows 2. The tapping pipe 3 is welded to the housing 4.

Other means for securing the feed pipe 7 and the tapping pipe 3 to the shell 4 are also possible by those skilled in the art.

Further, the inside of the housing 4 is a vacuum environment. The vacuum level inside the housing 4 is adjustable.

Specifically, sublimation of frozen materials is performed under high vacuum, in the process of pressure reduction, the frozen state of the articles in the dryer must be maintained, after the pressure in the dryer is reduced to a certain extent, the pressure is reduced to a required value for sublimation, and moisture in the frozen materials can be converted into water vapor in the process of sublimation.

Frozen material falls into interior spiral bucket 8 through inlet pipe 7 and obtains the bottom, and through the vibrations of vibrations base 1, moves frozen material to interior spiral bucket 8 top, gets into outer spiral bucket 5 top through bridging 6 for frozen material moves the bottom along outer spiral bucket 5 owing to frozen material self gravity, falls out by discharging pipe 3.

The continuous production can be realized by controlling the vacuum degree in the shell 4 and the temperature of the spiral barrel to fully dry the materials before the materials reach the discharging pipe 3.

In summary, in the spiral vibration dryer provided by the utility model, frozen materials enter the dryer from the feeding pipe, enter the spiral barrel through vibration of the vibration base, and dry the frozen materials through temperature heating of the spiral barrel and the whole vacuum environment of the dryer, so that the frozen materials finish the step of air drying in the process of rotating and transporting the frozen materials in the spiral barrel. The method effectively shortens the freeze-drying period, increases the productivity, improves the efficiency and realizes continuous production.
