Embodiment 1

[0019] The bamboo fiber lunch box of the present embodiment comprises the following steps with the environmental protection leak-proof sealing method:

[0020] The bamboo fiber lunch box includes a box body processed from bamboo and a lid matched with the box body;

[0021] Step 1. Mix and stir the potato starch and water to form a starch emulsion, then add the starch emulsion into the gelatinization tank, and then feed steam into the gelatinization tank to heat the starch emulsion to a temperature of 60°C, and keep it warm while stirring 2.5h to obtain starch slurry; the mass content of potato starch in the starch emulsion is 40%;

[0022] Step 2, apply the starch slurry obtained in step 1 on the surrounding edges of the inner surface of the lid, the thickness of the coated starch slurry is 0.15mm, and then the lid is processed under the condition of 165 ° C. The drying process of 2min forms the pregelatinized starch film on the inner surface of lid then;

[0023] Step 3. A...

Abstract

The invention discloses an environmentally friendly leak-proof sealing method for a bamboo fiber lunch box. The method comprises: mixing and stirring potato starch and water to form a starch emulsion, and obtaining starch slurry after gelatinization; and then coating the starch slurry on the box cover Then dry the inner surface of the pre-gelatinized starch film to obtain a pre-gelatinized starch film; then spray water on the pre-gelatinized starch film, wait until the pre-gelatinized starch film is completely dissolved, and then fasten the lid to the box body containing the food , the dissolved pregelatinized starch film is in contact with the upper edge of the box body, and the fastened bamboo fiber lunch box is sealed after the pregelatinized starch film is dried. The present invention utilizes the cohesive properties of potato starch after gelatinization to seal and connect the box cover with the box body, solve the problem of food liquid leakage during the transportation of the lunch box, and solve the problem of serious pollution of the environment by disposable lunch box waste. Satisfying the leak-proof demand in the actual use of bamboo fiber lunch boxes is conducive to realizing the large-scale promotion and use of bamboo fiber lunch boxes.

Description

technical field [0001] The invention belongs to the technical field of meal sealing, and in particular relates to an environmentally friendly leak-proof sealing method for a bamboo fiber lunch box. Background technique [0002] At present, disposable plastic lunch boxes are still commonly used in the catering industry, causing more pollution. A small number of bamboo fiber lunch boxes prepared by steam explosion technology have good environmental protection and economic benefits and can be used as substitute materials for plastic lunch boxes. However, due to the fact that a reasonable and environmentally friendly anti-spill sealing measure has not been developed yet, the plastic sealing method is still used for sealing. Although this plastic sealing method can solve the problem of sealing, when the lunch box is opened for dinner, the plastic sealing film material will be broken. Produce plastic waste, cause environmental protection problem, for some areas that prohibit plas...
