Embodiment 1

[0015] (1) Raw material selection: choose leeks with good color, fresh, mature, non-deteriorating, insect-infested, mildew-free, and pesticide-free, and remove roots and impurities;

[0016] (2) Pretreat leeks in the pretreatment device: clean the surface soil and impurities with clear water, drain, and cut the drained leeks into about 1 cm long;

[0017] (3) Carry out blanching and color protection to the leek in the blanching device: adopt the color protection agent to carry out blanching and color protection, the blanching time is 2min, and the color protection agent is 0.3% NaHCO 3 solution;

[0018] (4) Cooling device: quickly remove the blanched leeks, and immediately put them into cold water to cool;

[0019] (5) Beating device: Beat the cooled leeks with a beater for about 15 minutes;

[0020] (6) Homogenizing device: use the mixed adhesive of sodium carboxymethyl cellulose, sodium alginate and carrageenan and an appropriate amount of plasticizer glycerin to mix with...

Abstract

The invention discloses a preparation device of Chinese chive packaging paper. The device comprises a Chinese chive pretreatment device, a blanching device, a cooling device, a pulping device, a homogenating device, a degassing device, a curtain coating plate and a drying and molding device. The Chinese chive packaging paper produced by adopting the device has the characteristics of bright colors, paper forming property, tackiness, good uncovering performance, and strong tensile tension.

Description

technical field [0001] The invention belongs to the field of papermaking, in particular to a preparation process for leek wrapping paper. Background technique [0002] Present papermaking method is based on chemical method, and its process is that raw material (grass or wood) is cut into the chip (preparation) of certain size earlier, and raw material is boiled into paper pulp. Then rinse the pulp with a large amount of clear water (washing), and remove the coarse flakes and "pulp lumps" in the pulp by screening (screening). According to the requirements of the paper type, the pulp is bleached to a certain degree of whiteness (bleaching) with bleaching agent, then beating (beating) by beating equipment, and finally sent to the paper machine to pass through the screen part for water filtration, press dehydration, drying cylinder, and calendering , into rolls. Generally, large, medium and small paper mills are roughly the same in terms of their technological process, that is...
