Abstract
The present invention relates to PLA processing technique field, in particular a kind of method that the processing of PLA dixie cup is dehumidified with PLA crystallizing and drying.In the present invention, it is 50 DEG C -60 DEG C by using drying temperature to dry PLA crystallization, and the PLA crystallization after drying is subjected to cooling treatment, during cooling treatment, dust catcher and cyclone dust collectors are utilized to remove dust after blowing afloat the dust carried in PLA crystallization using cooling cold wind, this method, it is dehumidified using the method that low temperature drying dehumidifies, entire dehumidification process is completed in a circulation, closed environment, dust can stay in separator, without dust pollution and electricity consumption is small has the advantages that environmental protection, energy saving.
Description
Technical field
The present invention relates to PLA processing technique field, specially a kind of side that the processing of PLA dixie cup is dehumidified with PLA crystallizing and drying
Method.
Background technique
Currently there are most of method to PLA crystallization dehumidifying, mostly selection high temperature drying, and a series of
It is easy to produce dust in treatment process, therefore, proposes that a kind of PLA dixie cup processing is dehumidified with PLA crystallizing and drying regarding to the issue above
Method.
Summary of the invention
The purpose of the present invention is to provide the methods that a kind of processing of PLA dixie cup is dehumidified with PLA crystallizing and drying, by using baking
Dry temperature, which is 50 DEG C -60 DEG C, dries PLA crystallization, and the PLA crystallization after drying is carried out cooling treatment, in cooling treatment
In the process, dust is removed using dust catcher and cyclone dust collectors after the dust carried in PLA crystallization is blown afloat using cooling cold wind,
This method is dehumidified using the method that low temperature drying dehumidifies, and entire dehumidification process is complete in a circulation, closed environment
Separator can be stayed at, dust, and without dust pollution and electricity consumption is small has the advantages that environmental protection, energy saving, above-mentioned to solve
The problem of being proposed in background technique.
To achieve the above object, the invention provides the following technical scheme:
A kind of method that the processing of PLA dixie cup is dehumidified with PLA crystallizing and drying, the method for PLA crystallizing and drying dehumidifying include as follows
Step:
1) PLA is crystallized and is transmitted in drying box by conveyer, PLA is crystallized and carries out drying and processing, wherein drying temperature
Degree is 50 DEG C -60 DEG C, and drying market is 30-60 minutes；
2) the PLA crystallization after drying is poured into cooler bin, carries out air-cooled processing, during which, air-cooled taken up fugitive dust will
Cooler bin is sucked out by dust catcher, is imported in cyclone dust collectors, wherein the cooling duration of PLA crystallization was at 20-30 minutes；
3) the cooling PLA crystallization completed is imported in packing case, it is clear that the moisture inside the packing case passes through desiccant in advance
It removes, posts the drying for completing PLA crystallization.
Preferably, equipment used in method includes drying box, cooler bin, dust catcher, cyclone dust collectors and packing case,
Wherein, drying means used in drying box is low temperature drying, and the type of cooling used in cooler bin is air-cooled, air-cooled cooling
Temperature is 0 DEG C.
Compared with prior art, PLA is tied the beneficial effects of the present invention are: being 50 DEG C -60 DEG C by using drying temperature
Crystalline substance is dried, and the PLA crystallization after drying is carried out cooling treatment, during cooling treatment, is blown afloat using cooling cold wind
Dust is removed using dust catcher and cyclone dust collectors after the dust carried in PLA crystallization, this method is dehumidified using low temperature drying
Method dehumidify, for entire dehumidification process in a circulation, complete in closed environment, dust can stay in separator, no powder
Dustiness contaminates and electricity consumption is small, has the advantages that environmentally friendly, energy saving.

2) the PLA crystallization after drying is poured into cooler bin, carries out air-cooled processing, during which, air-cooled taken up fugitive dust will
Cooler bin is sucked out by dust catcher, is imported in cyclone dust collectors, wherein the cooling duration of PLA crystallization was at 20-30 minutes；
3) the cooling PLA crystallization completed is imported in packing case, it is clear that the moisture inside the packing case passes through desiccant in advance
It removes, posts the drying for completing PLA crystallization.
Wherein, equipment used in method includes drying box, cooler bin, dust catcher, cyclone dust collectors and packing case,
In, drying means used in drying box is low temperature drying, and the type of cooling used in cooler bin is air-cooled, air-cooled cooling temperature
Degree is 0 DEG C.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
