Abstract
The present invention discloses a disposable recoverable food packing box made of corn completely, which uses the complete corn as the main raw material. The complete corn is crushed into 130 to 200 meshes of powder, and then, 8 to 15 parts of water by weight is added into the power. Thus, slurry liquid is prepared by uniform agitation and sent into a bulking machine for bulking treatment. Subsequently, the slurry liquid is sent into an extruding machine for extrusion molding. A filming agent which is formed by mixing glucose-mannose glycan, glycerine, calcium hydroxide and water is coated on the molding slurry liquid and dried so as to realize forming. The present invention has the advantages of low production cost, no coating film leakage, heat resistance, water prevention, moisture prevention, freshness preservation and recoverable property. Besides, the present invention can be used as animals' and poultry's fine feed after recovered, and converted into organic fertilizer by the animals' and poultry's egestion. As a result, favorable product circulation is formed. The present invention is a green environment protecting product.
Description
Technical field:
The present invention discloses a kind of once-used recoverable food packing box made of corn completely and coating agent, relates to disposable foodstuff tableware production technical field.
Background technology:
At present, disposable and convenient tableware commonly used is made by wooden, papery or foamed plastic, and the former need consume a large amount of natural resourcess, and the productive costs height is so forbidden by country's order; And the foamed plastic tableware is commonly called as " white pollution ", is nondegradable, recycles very difficult, produce serious pollution for environment, though existing starch based, vegetable fibre kind disposable cutlery box are openly, its cost is about 2～4 times of foam cutlery box, promotes very difficult; Owing to added the colloid more than 30% in its batching, in degradation process, brought the soil pollution problem for the degradable cutlery box again.
Summary of the invention:
The present invention discloses a kind of once-used recoverable food packing box made of corn completely and coating agent, and purpose is intended to overcome a large amount of natural resources and enviroment pollution problems of consumption that existing wooden, papery or foamed plastic tableware exist.
Technical solution of the present invention is as follows: be primary raw material with the corn, be crushed to 130～200 order powder, the water that adds 8～15 parts by weight, stir and make slurries, be expanded under 159～180 ℃ the condition in 1 standard atmosphere, temperature, the temperature with bulking machine transfers to 120～150 ℃ then, is sent in the extruder by the material after expanded, extruder temperature is controlled at 120～150 ℃, and the thickness of basic material is 0.5mm;
Take off the row material by weight and make coating agent:
Glucose mannose glycan 0.8～1.5, glycerine 1.0～1.4,
Calcium hydroxide 0.01～0.05
Three kinds of mixing back water that add 30～50 parts of materials are modulated into viscous liquid to be poured in the coating machine, it is applied on the thick material of 0.5mm, coating thickness is 0.1～0.3mm, and the material that was coated with film enters in the shaping and drying machine, and drying and moulding makes product of the present invention.
The present invention compared with prior art has following good effect: make tableware by the full price corn, reduce production costs, the coated film is non-leakage, heat-resisting, waterproof, protection against the tide, fresh-keeping recyclable, can be used as livestock and poultry feed after the recovery, livestock and poultry are changed organic fertilizer into through draining, thereby forming the benign cycle of product, is a kind of Green Product.
Impervious degree when this product oil, water are molten altogether is to successively decrease after 48 hours, and when filling application vector, the inside face anti-mildew became induction period greater than 96 hours, and normal temperature (+28 ℃) can be preserved 6 months down.
The specific embodiment:
Embodiment 1
Get respectively that glucose mannose glycan 0.8kg, glycerine 1.0kg, calcium hydroxide 0.01kg are mixing to add the thick coating agent of making of 30kg water furnishing after evenly; Get full price corn 10kg and be ground into 150 order fine powders, add water 1kg and be modulated into slurries, put in the bulking machine, expanded condition is 170 ℃ of 1 standard atmospheres, and then with bulking machine temperature modulation to 120 ℃, the material after expanded is sent into extruder and extruded tableware, and send into coating machine, coating agent is applied to the tableware surface, and thickness is 0.1mm, gets product of the present invention.
Embodiment 2
Get respectively that glucose mannose glycan 1.2kg, glycerine 1.0kg, calcium hydroxide 0.03kg are mixing to add the thick coating agent of making of 43kg water furnishing after evenly; Get full price corn 10kg and be ground into 180 order fine powders, add water 1.2kg and be modulated into slurries, put in the bulking machine, expanded condition is 170 ℃ of 1 standard atmospheres, and then with bulking machine temperature modulation to 120 ℃, the material after expanded is sent into extruder and extruded tableware, and send into coating machine, coating agent is applied to the tableware surface, and thickness is 0.1mm, gets product of the present invention.
Claims (2)
1, the production technology of once-used recoverable food packing box made of corn completely comprises:
1), corn flour is broken to 130～200 order powder, the water that adds 8～15 parts by weight, stir and make slurries, be expanded under 159～180 ℃ the condition in 1 standard atmosphere, temperature, temperature with bulking machine transfers to 120～150 ℃ then, sent in the extruder by the material after expanded, extruder temperature is controlled at 120～150 ℃;
2), on the material that coating agent is applied to, coating thickness is 0.1～0.3mm, the dry materials moulding makes product of the present invention.
