Abstract
The present invention belongs to food package and dinner set and their forming method. The product contains paper pulp and waterproof and oilproof additive, and the prodn processes includes pulp beating, pulp mixing, pressing moulding, stoving, disinfection and packing. Its paper pulp and additive has no harmful effect on human body, and it is degradable and thus results in no pollution to environment.
Description
The invention belongs to a kind of packaging for foodstuff or tableware, particularly in a kind of hot pressing and vacuum molded paper tableware and forming method thereof.
Present various passenger traffic department and fast food eating and drinking establishment use plastics package and tableware for food, as the foamed plastic lunch box etc.Because plastic tableware is non-degradable, has brought serious " white pollution " to environment.At present, though tableware or packings such as lunch box, dish and bowl that paper is done occur, but all adopt cardboard compression moulding, or cut out paper mold folding bonding on machine and form, because paper fiber plasticity is very little, only be suitable for the shallow papery service plate of die cavity, dish etc., if dark chamber goods such as compacting lunch box, then because the folding pattern and the distortion of paper will appear in the difficult stability of the not plasticity of cardboard and moulding in four jiaos in lunch box.This class carton strength paper for bearing than at the bottom of the big load box, must adopt thicker press polish cardboard, thereby cost is also more expensive simultaneously.In addition, the leftover pieces that stay can't directly utilize, and cause waste.Recently also useful paper pulp molding pressure injection egg pallet, the fruit pallet, and these packings and apparatus all belong to the packaging for foodstuff of non-immediate access, needn't sterilize, bleaching, grease proofing and high temperature resistant etc., shape and specification all are not strict with.
The objective of the invention is at problems of the prior art, propose a kind of packaging for foodstuff or tableware with paper pulp pressure injection type, and the packaging for foodstuff of available immediate access or tableware.
Another object of the present invention is in order to make the tableware with the paper pulp injection-compression molding, to propose the forming method of a kind of hot pressing and vacuum molded paper slurry tableware.
A further object of the present invention is that aforesaid custom-designed mould of paper pulp injection-compression molding tableware and mould are annotated machine.
Hot pressing of the present invention and vacuum molded paper tableware are made up of paper pulp and waterproof and oilproof additive, and the weight of waterproof and oilproof additive wherein is the 0.1-2% of paper pulp weight.Described paper pulp comprises reed straw pulp 50-70%, wood pulp 30-50%.Described waterproof and oilproof additive is an Organic fluoride, aluminum sulfate, alum, cured or rosin, and they can use separately or be used, and wherein the ratio of oil-proofing agent and waterproofing agent is 1: 3.
The method of hot pressing of the present invention and vacuum molded paper tableware comprises and draws together following steps:
1) paper pulp or pulp board are put into disintegrating machine and make paper pulp, put into mixing hollander again and stir, and put into the waterproof and oilproof additive in proportion;
2) paper pulp for preparing is squeezed into vat or passed through the mould that the paper pulp shower nozzle injects the mould shaper with pump;
3) die in the mould shaper is vacuumized with the vacuum machine earlier, get tableware base goods with the hot pressing of hot pressing punch behind the absorption pulp material;
4) tableware base goods in sending into automatic Drying tunnel of controlling of band temperature or drying baker, conveyer belt are dried;
5) again after sterilization, with finished product packing.
Described mould comprises can evacuated die and the punch of hot pressing, and mold inside has meshy surface or ribs.
Described mould notes machine is that multimode is arranged swinging mould notes machine, it comprises vat, the vacuum die, the hot pressing punch, rotate and transfer equipment, vacuum die and hot pressing punch are installed on the rotating polygonal wheel carrier, wherein the vacuum die in rotation, immerse successively hot pressing punch in the vat then with the vacuum die in paper pulp turn on the transfer equipment after being hot pressed into the tableware base.
Described mould notes machine is that single mode multimachine arranged type mould is annotated machine, it comprises the paper pulp shower nozzle, the hot pressing punch, vacuum die, transfer equipment, slew gear, manipulator and cylinder thereof, wherein the paper pulp nozzle is adjacent with the vacuum die, and nozzle can spray into paper pulp in the die, the hot pressing punch is contained in the two ends of the mechanical arm of die and conveyer belt top, and mechanical arm is handled by its manipulator cylinder and slew gear.
Hot pressing of the present invention and vacuum molded paper tableware and a product packing have the following advantages and characteristic:
1, the mixed pulp of the straw pulp of a paper tableware of the present invention and wood pulp can satisfy the structural strength requirement of tableware like this, can reduce the tableware cost again;
2, used mold cavity calculates and design through precision among the present invention, make the paper fiber have different shapes and structure by the requirement of strength of tableware different parts, utilize the molten moving property of paper pulp fully, make the mutual dragline of fiber, and be provided with and strengthen short muscle, save paper and will guarantee enough intensity again, mould is simple simultaneously, for ease of maintenaince.
3, aim at and produce mould that hot pressing of the present invention designs with the vacuum molded paper tableware and annotate machine and be divided into multimode arranged type swinging pattern according to working condition and annotate machine and single mode multimachine arranged type mould notes machine; The former definitely mould commentaries on classics of not stopping transport, can inhale again and send the moulding tableware to send on the drying conveyor, floor space is little, and latter's multimachine is produced simultaneously, the efficient height, it can come the both sides of conveyer belt, produces polytype tableware simultaneously, lunch box, bowl, dish, fast food pallet, ice cream, tablewares such as box, and adopted pneumatic quick absorption manipulator, the low tableware base of moulding is arranged on the conveyer belt.
4, used paper pulp and the additive of tableware all has no adverse effects to human body, and meets the hygienic requirements of food utensil fully through high temperature compacting, oven dry and sterilization;
5, because tableware of the present invention or packaging for foodstuff have waterproof, grease proofing, sterilization, heatproof, indeformable multiple function under 100 ℃ temperature, has the corrosion degradation characteristic again, free from environmental pollution, just degradable in southern area one month, northern area also can be degraded in two months, as in humidity, sleety weather, it is then faster to degrade.
For further specifying the concrete technology and the structure of paper tableware of the present invention, be described with reference to the accompanying drawings and in conjunction with the embodiments, its accompanying drawing has:
