秸秆制作一次性餐盒的制作

The softened wheat straw will be cleaned and separated in a hydraulic straw crusher. When the straw enters the hydraulic straw crusher, add circulating water at the same time to control the concentration of straw water mixture at about 10%. After treatment, the sediment, leaves, ears, broken grass nodes and other sundries in the straw are broken and discharged with water. Stones, iron blocks and other heavy objects are discharged from the surrounding stone discharge pipe under the action of centrifugal force, and finally leave clean straw fragments.

秸秆分解器分解后，秸秆-水混合物被送到洗涤系统进行清洗和浓缩，只留下纤维素、半纤维素和反式木质素。清洗后的浆料需要通过挤出机进一步浓缩，以获得秸秆一次性餐盒的原料。

After the straw decomposer decomposes, the straw water mixture is sent to the washing system for cleaning and concentration, leaving only cellulose, hemicellulose and trans lignin. The cleaned slurry needs to be further concentrated by extruder to obtain the raw material of straw disposable lunch box.

一次性餐具有个较为重要的质量要求，即盛的汤汤水水不能漏、有油的食物不能漏，因此需要在其中加适量防油剂和防水剂，但须是食品类添加剂方可。配制好的浆料经过管道输送到一次性餐具定型成型机。定型时，需将金属网制出的食品盘模具放于机器上，而后将设备落下，待浆液均匀的放到容器里后，打开真空抽吸泵开关，容器中浆液会缓慢下落，这种生产方式叫抽漏法。此法可清理掉浆液中多余的水分，使浆料中的固体成分均匀附着在模具内壁上。当关闭开关将金属网模具拿出来时，便可取出湿浆胚。而后，将湿浆胚转移到凝结机。定型机的顶部和底部有一个模具。当上下模具扣在一起时，它们通过170℃到180℃的蒸汽，经过热压榨的方法使一次性餐盒含水量达8%左右，这时餐具便初具雏形。

There is an important quality requirement for disposable tableware, that is, the soup can not leak, and the food with oil can not leak. Therefore, it is necessary to add an appropriate amount of oil and water repellent, but it must be food additives. The prepared slurry is transported to the disposable tableware shaping machine through pipeline. During finalization, the food tray mold made of metal mesh shall be placed on the machine, and then the equipment shall be dropped. After the slurry is evenly placed in the container, turn on the vacuum suction pump switch, and the slurry in the container will fall slowly. This production method is called leakage pumping method. This method can remove the excess water in the slurry and make the solid components in the slurry adhere to the inner wall of the mold evenly. When the switch is turned off to take out the metal mesh mold, the wet slurry embryo can be taken out. Then, the wet slurry embryo is transferred to the coagulator. There is a mold at the top and bottom of the setting machine. When the upper and lower molds are buckled together, they make the water content of the disposable lunch box reach about 8% by hot pressing through the steam of 170 ℃ to 180 ℃, and then the tableware begins to take shape.

成型餐具边缘不平，影响美观，因此，有需要通过切边工艺来生产出美观的餐具。切边机上使用的模具与定型机和成型机上使用的模具整体相同。固定好餐具后，打开机器，餐具多余的边缘会被压平，成为可以使用的一次性餐具。

The edge of the formed tableware is uneven, which affects the beauty. Therefore, it is necessary to produce beautiful tableware through the edge cutting process. The molds used on the trimming machine are the same as those used on the setting machine and forming machine. After fixing the tableware, turn on the machine, and the excess edges of the tableware will be flattened to become disposable tableware.

稻草餐具出厂前应进行检查、消毒和包装。在检验过程中，须检查外观质量；并对每批餐具进行抽样检验，包括物理力学性能和微生物指标。虽然稻草餐具在生产中有严格的卫生控制标准，但在出厂前应进行臭氧消毒和紫外线消毒，以杀灭一次性餐盒表面的细菌繁殖体，如孢子和其他菌类。

Straw tableware shall be inspected, disinfected and packaged before leaving the factory. During the inspection, the appearance quality must be checked; Sampling inspection shall be conducted for each batch of tableware, including physical and mechanical properties and microbial indicators. Although there are strict hygiene control standards in the production of straw tableware, ozone disinfection and ultraviolet disinfection should be carried out before leaving the factory to kill the bacterial propagules on the surface of disposable lunch boxes, such as spores and other fungi.
