Abstract
A technology for manufacturing plant fibre products, belonging to package field, includes such steps as shaping the product with paper pulp, pressing for fixating its shape, baking, fixating shape further, cutting, sterilization and packing. Its advantages are low cost, high automatization level and output, good appearance, and high quality.
Description
The present invention is a kind of production method of plant fiber products, belongs to the packing technique field.
The production of plant fiber products needs just can finish through many procedures such as slurrying, shaping, oven dry, shaping, sterilization and packings.Production technology is selected unreasonable, not only influences its product quality, but also will strengthen investment, waste energy, improve production cost, thereby hindered applying of plant fiber products, slow down the paces of " moulding with paper generation ", become the stumbling-block of elimination " white pollution ".Resemble that present some producers adopt by the modular assembled production line of unit, be difficult to realize large-scale production, its product also can only be an one-sided smooth, another side is rough, do not meet the hygienic requirements of packaging for foodstuff, product specification is difficult to improve, and operator's work situation is abominable, labour intensity is big, is difficult to realize automated production.Also have some producers to adopt the production technology of slurrying → shapings → transfers → oven dry → cross cutting → sterilization → packings, this production technology is owing to being to dry under free state after the product shaping, causes the product after the oven dry to be out of shape seriously the yield rate reduction; If the moisture content inequality of product has brought difficulty again for setting.In addition, also have some other production method, but all have big energy-consuming, automaticity is low, and labour intensity is big, the shortcoming that poor working environment, product quality are difficult to improve.Given this, at present paper pulp moulding product apply very slow.
Purpose of the present invention is exactly the problem at above existence, creates the new technology that a kind of plant fiber products is produced.Use this explained hereafter, its production cost of products is reduced, quality improves, and output is big, and automaticity is higher.
Plant fiber products production technology of the present invention, its concrete grammar is: after the paper pulp of having accomplished fluently is fully stirred with agitator, additive (being applicable to internal sizing) such as add oil resistance, block water, flow to forming machine, after being shaped through forming machine, shift out from forming machine by transfer device, enter press apparatus, with mould pressurization (mould also can be heated in case of necessity), fully squeeze, slough the part moisture content of product, revise the surface of product, the moisture content of product is further reduced, and geometry is rule more, and then the row oven dry.Treat to carry out shaping by special equipment after its oven dry, make after its regulation that meets product standard,, become qualified products through the detoxicating packing.
Adopt the advantage of the production method of plant fiber products of the present invention to be:
1. after shaping, can further reduce the moisture content of product, therefore the requirements at the higher level of equipment vacuum saved the energy, reduce production cost thereby reduced through squeezing.
2. adopt slurrying → shaping → squeezing (can heat) → oven dry → shaping → sterilization wrap technology, reduced the distortion of product when oven dry, can improve the qualification rate of product greatly, guarantee product quality.
3. the product of this explained hereafter can be guaranteed the feature that the two sides is smooth, and the relevant health that meets country detects requirement.
4. this technology can be sloughed the most of moisture content in the product in shaping and transfer process, has shortened drying time.
5. with this explained hereafter automaticity height, output is big, is beneficial in enormous quantities, the large-scale production of tissue.
6. after being shaped and squeezing, can carry out surface spraying oil resistance waterproofing agent (being used for outer applying glue), oven dry then.
The present invention is specially adapted to the production of disposable plant fiber snack container.For the disposable plant fiber snack container, both required profile attractive in appearance, require the energy oil resistance again, block water, certain intensity and deflection are arranged, also must meet the sanitary standard of packaging for foodstuff.The product that this method is produced, the two sides is smooth, and the shape of product and thickness can be by artificial directly controls, and whole process of production can all realize automation.
Specific embodiments of the present invention is as follows:
With pulper and fiberizer, raw material (pulpboard etc.) is smashed, wear into the underflow that concentration is 8-12%, after in stock tank, fully stirring, send into and join stock tank with agitator.In joining stock tank, stir on one side, add auxiliary material (being used for internal sizing) such as oil resistance agent and waterproofing agent on one side.And then send in the pulp storage tank, it is the thin pulp of 1-3% that thin up becomes concentration, delivers to stock pump in the slurries circulatory pool of forming machine, uses for forming machine.Forming machine utilizes the vacuum suction slurries, on its mould, form product, after forming machine dewaters for the first time, shift away from forming machine by transfer device, deliver to press apparatus, pressurization also keeps 1-60 second (when pressurization, can make the press apparatus heating), carries out the dehydration second time and does setting just, make its moisture content below 75%, can carry out surface spraying oil resistance waterproofing agent (being used for outer applying glue) then, deliver to the drying equipment oven dry again, bake out temperature is between 100 ℃～170 ℃.After treating substantially dry (moisture approximately about 15%), by shaping device formalize again, cutting, pass through sterilization wrap at last, finish the production process of its product.
Claims (4)
1. the production method of a plant fiber products, it is characterized in that: the product after will being shaped with forming machine by the paper pulp that raw material (cardboard) made, send into the press apparatus pressurization by transfer device, can heat simultaneously, and kept for 1～60 second, and then deliver to drying plant and dry, make its moisture content below 65%, carry out shaping and cutting by shaping device again.
2. the production method of plant fiber products according to claim 1 is characterized in that moisture content through the product of squeezing is below 75%.
3. the production method of plant fiber products according to claim 1, the temperature that it is characterized in that the press apparatus pressurizing mold is between 30 ℃～180 ℃.
4. the production method of plant fiber products according to claim 1 is characterized in that trimming can finish the setting and the cutting work of product simultaneously.
